When Rui entered 6th grade in school, he knew one thing for certain:

He needs to protect Tsukasa’s innocence.

Having read plenty of books above his recommended age rating and his mother’s biology books, he already knew everything he needed and more about puberty. To even elevate his research, he did look up some unsightly stuff on the internet, but it was only for research. He didn’t even get hard. It’s a biological transition of a human body to reproduce. The sudden uprise in hormones causes drastic changes to the body and mind, from basic testicular and penile growth to mood swings and the so-called “rebellious phase."

Some children are surprised by their changes, but he was well prepared for it. It’s still only 6th grade, so there’s barely any really noticeable changes, besides his growth spurt and some girls’ already grown breasts. But the boys in their class have seemingly acquired sexual attraction, and sex quickly became the hot topic between 6th graders. He didn’t care, but…

Tsukasa was too innocent for this kind of talk yet.

Tsukasa was his one best friend for forever. Having met in a playground when Rui transferred from another school due to his family move, the blonde boy quickly got close to him when he saw Rui reading a book of a show Tsukasa saw, and ever since then they've been attached at the hip. Rui and Tsukasa had play dates every weekend, after class they did homework together, and every other free time they had, one of them would find the other, and they’d spend it talking away. At first the very extraordinary personality Tsukasa had pushed him off a bit, but he quickly grew fascinated with him. Tsukasa was scared of bugs to the point of crying when seeing them (even though after he would deny it, saying boys never cry), he could cook basic dishes, and most importantly, he loved shows.

Tsukasa loved shows, and Rui loved directing them. Tsukasa was the second-ever person so far who was willing to play along with his ideas, who wasn’t scared. He would do it so passionately and with effort too, and it wasn’t long before Rui’s cheeks would grow warm thinking of him.

But Tsukasa had one serious problem—he was seriously clueless about everything. While he knew some trivia from shows and books, his grades could be better, he struggled with the multiplication table and with English tenses, but he always tried to learn more and begged Rui to teach him. In one word, he was cute.

Which is why, obviously, Tsukasa had no idea what puberty, sex, a vagina, or a penis was. For God's sake, Tsukasa thought babies are delivered through birds to their chosen parents. Tenma didn’t start his puberty yet, a fact that Rui verified himself in the P.E. changing rooms. His penis was so tiny he couldn’t even see it properly from the side, there was no hair on him, and the way his skin was shiny could make a newborn envious. When their classmates would start discussing who between their girls has the bigger boobs, Tsukasa would tilt his head before Rui would drag him away somewhere and distract him.

“Rui, how did you grow tall if you don’t eat vegetables? ”Tsukasa would ask while they were coloring their next show props together. They were over at his house, and Rui was guilty of sneaking a few glances at the way Tsukasa’s butt looked in his shorts. Tsukasa can’t know at all.

“Well, that’s obviously because grown-ups lied and we don’t need to eat vegetables.”

“No way! My mom said so, and she wouldn’t lie to me! You’re lying!” Tsukasa turned to him, putting down a crayon and scooching closer to his friend. “Tell me the truth!”

Ah, Tsukasa-kun is so innocent. I want him to stay like this for as long as possible.

And Rui succeeded somehow. When boys in class started showing each other photos of what they found online, Rui would quickly catch Tsukasa’s shows with a new show playing next week, or when others started showing signs of acne, he told Tsukasa it’s because of a poor diet (which is true technically!).

But Rui couldn’t control what Tsukasa did or heard while they were in their own homes, separated from each other.

Or what Tsukasa’s parents kept in their house, for that matter.

…It was supposed to be a normal sleepover.

“Rui!” A loud voice rang out through the whole classroom as Tsukasa plopped on a seat next to him with his usual sparkling eyes. He was fidgeting with his fingers as he spoke. “You won’t believe what I found!”

“If it got Tsukasa-kun this excited, it must be fun." Rui replied, not lifting his eyes off his new robot creation.

“I found so many movie DVDs in our house’s storage! Movies I’ve never watched or heard about! I’m sure even Rui never saw them!" he proclaimed, talking so fast that he’s sure Tsukasa isn’t breathing. “Which is why, Rui, you must absolutely come by my house tonight! Tell your parents and come over after 4 o’clock!!!!”

“Did your parents agree to that? ”he asked back, already knowing his parents will only be happy to send him to a sleepover with his best friend.

“Yeah. They’re out of town again for a day or two, so they told me, "I can bring you over." Tsukasa nodded before pulling out his pegasus-shaped pouch from his pocket. He opens it before Rui’s eyes and sees an appropriate amount of bills in it. “They gave me this money so we can order pizza and buy ice cream! We will be all alone!”

Tsukasa was smiling from ear to ear, and something about how one of his baby teeth fell out recently and he had a cute gap made Rui want to pet him like a puppy. He smiled back, reaching out to zip up his pouch. “You should keep it safe, not show me, Tsukasa-kun. But, of course, I’ll be there today. Let’s just stop before my house so I can grab a change of clothes.”

Tsukasa nodded with enthusiasm before the school bell rang, and Tsukasa hurriedly ran off to his seat. Watching him from the side, the idea of a sleepover had him so excited that his feet were swinging. Tenma was still too short to reach the floor. Rui smiled, feeling his face warm up.

After class, both of them made a quick stop to Rui’s house first, with Rui’s mom excitedly packing a mini bag for him and sending him off with a little bit of money. Rui also packed his favorite toys and books, just in case. They obviously didn’t tell her that there won’t be any parental supervision, but it’s not like she asked them anyway. Tsukasa waited for him outside, for some reason embarrassed to talk with Mom due to “not being prepared” and “looking unsightly right now." Rui just poked his side and laughed when Tsukasa jumped away.

“Let’s buy ice cream and snacks here!” They stopped in front of a convenience store in Tenma’s neighborhood. Walking in, they stormed the candies section, with Tsukasa visibly holding back from getting everything they wanted, because “a true star shouldn’t eat too many sweets or his teeth will hurt!”Rui didn’t really listen as he put down another bottle of Ramune in their basket.

“I’m home!”

“Pardon the intrusion.”

Tsukasa barely had time to step out of the entryway before Rui slipped off his shoes and padded inside, hugging his bag to his chest like he already belonged there.

Tsukasa turned on his heel and hit one of his many theatrical poses, his hand on his heart. “Ahem! Then, as the host, I shall personally guide you to the grand chambers of tonight’s event!”

Rui grinned. “You mean your room?”

“W-Well, yes, but don’t ruin the mood! And it’s not a room - it’s my chambers!” Tsukasa’s face turned pink.

Rui laughed and followed him upstairs. Tsukasa’s room was the way it always was, and somehow each time Rui would be a bit surprised at how tidy and neat it would be. Toys would always be cleaned up and be in their designated boxes, books would be carefully stacked on his table, and his bed would be perfectly folded. What a perfectionist.

He busied himself immediately by setting down the shopping bag from the convenience store on the low table. “We should order pizza first before it gets late!”

They sat shoulder to shoulder on the floor, leaning over Tsukasa’s phone and a pizza-store booklet they kept home as they chose their favorites.

“Corn is good.”

“Ew. Corn does not belong on pizza, Tsukasa-kun.”

“It does. You just have no taste.”

“Isn’t there anything that has no vegetables?”

Tsukasa gasped. “Pizza with no vegetables isn’t real! The paste is tomato!”

Rui just shrugged, pointing to a pepperoni. “It doesn’t matter because it’s been processed and isn’t a tomato anymore.” Tsukasa stared at him while Rui held back a giggle. In the end, they compromised on half pepperoni, half cheese, and an extra side of fries that Tsukasa claimed they absolutely did not need but ordered anyway after Rui gave him a look.

Once the order was placed, the anticipation of actually spending the night together seemed to hit both of them at once. Rui was unloading his bag with toys and pajamas while Tsukasa was fiddling with the little TV that his parents bought for him and Saki to watch cartoons together, instead of taking up the family TV downstairs. While Rui was distracted, Tsukasa opened his closet and pulled out an extra blanket and pillow, carefully placing them. Pushing chairs together and hanging a blanket over them gave him the perfect pillow house for the cozy-movie-watching experience they needed! Rui helped him bring in some pillows until just settling in them, watching Tsukasa run around the room picking up pillows, toys, and blankets.

When Tsukasa came back and hesitantly gave Rui a pink bunny plushie, pretending like it was no big deal, he saw right through him. He remembers seeing Tsukasa sleep with it.

“You’re giving me your favorite?”

“W-what?! I’m already 12 years old, I don’t have favorite plushies!”

“But you do.”

"No, I don’t! I-it’s just… as a host, it’s only natural to give the guest the best treatment!” Tsukasa crossed his arms and looked away. Rui smiled softly, hugging the bunny and mouthing a thank you.

The pizza arrived not long after, and the two of them hurried downstairs when the intercom buzzed, trying not to look too suspicious even though there was nobody there to suspect them in the first place. After paying the delivery man, they carried them back to his room.

A few minutes later, Tsukasa came back upstairs with much more noise than Rui expected.

There was a loud thump in the hallway, followed by Tsukasa’s strained voice.

“I-I found them!”

He appeared in the doorway, dragging a huge cardboard box that looked almost as big as he was. Dust clung to his sleeves, and his hair was slightly messy from apparently digging through storage.

Rui blinked. “That many?”

Tsukasa puffed out his chest proudly, despite clearly being out of breath. “My family kept so many old DVDs! We can watch anything we want tonight!”

He shoved the box onto the floor between them with a triumphant grin.

Rui leaned over, curious, and pushed aside the flaps. Inside were dozens of DVD cases, stacked haphazardly. Some had handwritten labels, some had old movie covers, and some were in plain sleeves with no titles at all.

“Whoa…” Rui murmured, reaching in.

Tsukasa sat beside him, already excitedly digging through the pile. “There should be some action movies, and maybe old stage recordings too! Or maybe something with scary monsters—"

Rui pulled out one random case.

Then another.

Then his expression changed.

He stared at the covers for a second, eyes widening, and losing all color in his face. He quickly flipped one over, then another, as if hoping he was mistaken.

He was not.

Rui went completely still.

The whole box was a collection of porn.

Tsukasa, meanwhile, had already pulled out three discs and was happily holding them up. “Look! I found one! We can start with this one, and then— Rui? What’s wrong?”

Rui slowly looked up at him. Tsukasa was smiling innocently, completely unaware. Usually he would admire his smile, but his eyes were focused on the fact that Tsukasa was holding a DVD sleeve that had a woman with big breasts sit in a bikini as two men held her up by the hair.

Rui glanced back at the box and at Tsukasa. He immediately shoved the ones in his hands and Tsukasa’s hands back into the box.

“R-Rui?! What are you doing?!”

“Uh… Tsukasa-kun.”

“Yes?”

“These aren’t… movies.”

Tsukasa tilted his head. “What do you mean? They’re DVDs.”

Rui rubbed his face. How was he supposed to explain this? He lowered his voice. “I think some of these are your parents’ private DVDs.”

Tsukasa blinked. Then blinked again, tilting his head to the side.

“…Private?”

Rui nodded awkwardly, not meeting his eyes. “Like. Grown-up stuff. Not for us.”

Tsukasa frowned immediately, clearly offended. “What? No, they were in the storage room. My parents probably just forgot about them. They don’t really watch movies like me and Saki anyway.”

“No, Tsukasa-kun, seriously. We shouldn’t watch them.”

“You’re making things up.” Tsukasa crossed his arms, brows furrowing.

“What? I’m not!”

“You didn’t even look at all of them!”

“I looked at enough.” Rui argued back.

Tsukasa’s cheeks puffed up in irritation. “How would you even know what they are supposed to be if you didn’t watch them?”

The question hit a little too directly.

Rui looked away, suddenly very interested in the pizza box. “I just know, okay?”

Tsukasa stared at him, upset and angry, but also confused in that way only eleven-year-olds could be when they felt left out of something.

“Rui is a liar! You just don’t want to watch my DVDs with me!”

Rui sighed. He didn’t want Tsukasa to be upset, but he also absolutely did not want him putting one of those discs into the player. He needed to protect his innocence for as long as he could! So before Tsukasa could grab another case, Rui reached out and shut the box.

Firmly.

“We are not watching anything from this box.”

Tsukasa gasped like he had been personally betrayed. He tried pushing him away.

“You can’t decide that! I’m the host!”

“I can if it saves us both from being traumatized.”

Tsukasa stared.

"What does 'traumatized' even mean!?”

Rui immediately regretted everything. Tsukasa’s eyes narrowed suspiciously, but then his gaze dropped to the box again. For the first time, he seemed a little uncertain.

“…Are you serious?”

Rui nodded once.

Tsukasa’s expression slowly shifted from annoyance to sadness as the possibility started to sink in, definitely, he still didn’t understand, but Rui was so serious that it had to be bad.

Tsukasa froze with his hands still on the box, then slowly turned away. His face was red, but not from embarrassment anymore.

“You’re lying.”

“I’m not,” Rui said quietly, still keeping one hand on the lid.

Tsukasa’s brows furrowed. “How can you even know just from looking at them? You picked up two! You know, you can’t judge a book by its cover!”

“W-well yes, but this is a special case!” Rui blurted out, then immediately regretted how harsh that sounded.

Tsukasa stiffened. For a second, he just stood there, clutching the side of the box. Then his mouth pressed into a stubborn line Rui knew all too well.

“You’re just saying that because you don’t want to watch movies with me...”

“That’s not—"

“It is!” Tsukasa snapped, louder than before. “Rui always acts like he knows everything! I’m actually the older one! Maybe they’re just normal DVDs and you’re making fun of me because I never watched them before!”

Rui blinked. Tsukasa rarely got genuinely mad at him, and it caught him off guard enough that he didn’t answer right away. His brain was still processing it. His Tsukasa-kun is mad? At him?

That silence only made Tsukasa more upset.

He hugged the box protectively, as if Rui had insulted something personal. “Fine! If you don’t want to watch them with me, then don’t.”

He grabbed one of the plain cases from inside and held it tightly.

“I’ll just watch them by myself!!

Rui’s stomach dropped.

No, no, absolutely not.

He could already picture Tsukasa proudly shoving one into the player, all alone, completely unaware, and then—

Rui squeezed his eyes shut. That would be catastrophic. For Tsukasa’s healthy mind and for Rui’s heart. He absolutely has to stop this, even if it costs upsetting Tsukasa. It’s for his own good!

Now that he is thinking all his options out… At least if he stayed there, he could stop it before anything got too far. Some kind of control over the situation. Maybe he could make up some excuse to turn it off midway. Or usually, stuff like that has a long and low-quality acting before anything starts, so maybe Tsukasa will get bored. Or he can pretend the DVD player is broken. Spill Ramune on the remote. Break it into two and ask his mom to pay his parents the damage later. Something.

But more than that—

Tsukasa looked genuinely upset at him.

Not just annoyed and mad. Was he this hurt overthinking that Rui was making fun of him? Tsukasa has complained before about how Rui is smarter than him, but he didn’t think he was insecure about it. And Tsukasa’s grip on the DVD case was so tight his knuckles were white. He really… wanted to watch this.

Rui hated that look. One where Tsukasa was upset and would purse his lips and stare at the ground. He always gave in too fast when Tsukasa looked like that. A smile fit his face much more.

“…Wait,” Rui said, quieter this time.

Tsukasa didn’t answer, but he stopped moving. Tsukasa didn’t even look at him.

“Tsukasa-kun, I didn’t mean it like that... I didn’t want to make fun of you.” Rui looked away, rubbing the back of his neck.

Tsukasa stayed silent, and Rui sighed. It’s fine. He can… think of something. And explain it later to Tsukasa.

“If you really want to check one, then… fine.”

Tsukasa blinked and lifted his face up. Rui’s face immediately twisted like he already knew this was the worst decision he had made all week. But he tried smiling to cheer up his friend.

“We can watch one,” he said carefully, holding up a finger. “Just one. Together. Don’t watch these on your own.”

Tsukasa’s expression shifted at once. He was clearly happy but quickly remembered he had to act tough and lifted his chin up.

“…Very well. I forgive you, Rui! I’m sorry for calling Rui a liar too…” Tsukasa added, with a blush in his face. “But we can finally watch now!”

Rui swallowed, watching Tsukasa look back into the box and seemingly starting to pick. I am absolutely going to regret this afterward.

Tsukasa dug through the box before something caught his eye. He pulled out a DVD that made Rui swallow. A high school girl was on the cover, visibly sweaty and undoing her tie. The writing was covered with white tape, with something barely readable on it. Why would Tsukasa’s parents even keep so much porn in their house?? And why would they sign each one? What, did they try archiving them by genres and tropes? Maybe he shouldn’t imagine his best friends’ parents’ sexual life, but how can he when it’s right in front of him? He can only imagine what else they’re keeping in that storage, he has to somehow get Tsukasa to stop snooping there until he finds something phallic-shaped. He only nodded back to Tsukasa, and he excitedly put the DVD in, careful not to scratch it. He wishes he would scratch it.

Rui sat beside him, very stiff, already preparing himself to lunge for the stop button the second anything weird happened. Tsukasa, still a little pouty, inserted the disc into the player.

The screen flickered. The DVD menu loaded slowly, old and grainy. Both of them stared at the TV in complete silence. Rui realized he was praying to gods that the DVD was busted and didn't work anymore.

The screen flickered to life. At first, it looked completely normal.

Soft music played over a shot of a city at night. Then a woman appeared, walking from school wearing a too-short skirt that barely covered anything and thigh-high socks that no high school would allow. The video quality was old and grainy, but it really did look like some random romance movie.

“See? It’s just a movie.” Tsukasa crossed his arms, still clearly offended, but proud of himself. “Rui is a scaredy cat sometimes.”

Rui didn’t answer. He was staring at the screen with deep suspicion. His hands were clenched in his lap.

The girl met a grown-up man in a suit at a train station, and Rui mentally started judging Mr. and Mrs. Tenma in his head. He saw this plot several times during research. They’re going to get together in one really packed train, and the man will harass the woman until they get off together and have intercourse somewhere, like the toilet or a love hotel.

Tsukasa relaxed almost instantly. It was just a regular romance movie. Makes sense - his parents love each other, so why wouldn’t they watch romance movies together?

“Hmph. You got scared over this? It’s just romance.” He grabbed another slice of pizza, looking smug. “Honestly, Rui, you’re too dramatic sometimes.”

Rui frowned. There was no title screen. No opening credits, the director, or the actors. And the camera angles felt… super weird. Like someone had skipped the actual start of the movie and was instead trying to make the viewer look at the woman’s big breasts and behind.

His suspicions played out truthfully, of course, they ended up squeezed in a train, and we saw the man rub against the girl.

Rui’s entire body went rigid.

“Oh no.”

Tsukasa blinked. “What?”

The music changed. The train was quiet, but they could hear the girl gasping. The girl is acting confused, even when the man’s hands start holding her hips, and Tsukasa just stares at the TV, chewing casually.

“…Why are they doing?” he asked. “This is kind of boring.”

“Then how about we watch something else?" Rui suggested, praying it works.

“Since we started, we need to finish it, Rui! Starts don’t quit!" and that’s exactly when the AMV started getting hot.

The scene shifted in a way that made Rui instantly flinch like there was a jump scare. It was still not something Tsukasa would fully understand, but it was very obviously not a normal movie for kids.

The man on TV unzipped his zipper and pulled down the girl's panties, and before Rui could reach and stop it, it was on full screen. He hurriedly, falling over himself and their pizza, grabbed the remote, but that only made the situation worse, as the screen was now paused exactly on the man’s black and pretty gross penis.

“A~ah!”

"C-crap…!" Rui couldn’t think before looking back at Tsukasa’s reaction.

Tsukasa blinked once.

Then twice.

His slice of pizza slowly lowered.

The room went dead silent except for the TV.

Tsukasa tilted his head, confused. “What is that-?”

Rui lunged for the remote and hit pause so hard the battery cover nearly flew off. The frozen frame made everything ten times worse.

Rui scrambled and hit stop instead, ejecting the disc with a loud mechanical whir, and the TV shut down.

Neither of them moved.

Tsukasa was staring at the blank TV screen, his expression caught somewhere between confusion and trying very hard to understand something that made absolutely no sense.

“…Rui.”

Rui wished he could evaporate.

“…Yeah?”

Tsukasa looked at him slowly.

“What was that?”

Rui made a sound that was somewhere between a cough and his soul leaving his body. What is this question?!

“It’s— it’s not…” He pressed both hands over his face before going through his hair with them. “I told you we shouldn’t watch it.”

Tsukasa frowned, still not really upset anymore, just bewildered. “But what kind of movie even is that? Ignoring the girl making weird noises, the man pulled out something weird from his pants.”

Rui’s ears were burning so badly he thought he might actually pass out. Tsukasa turned fully toward him, eyes wide with genuine curiosity now.

“You know, right? "Tell me!" Tsukasa pulled on his sleeve, not noticing that Rui is overheating.

“…Tell you w-what?" Rui mumbled, trying to breathe. There’s no getting out now. Tsukasa saw it and won’t calm down until he finds the answer. And if he doesn't, Tsukasa will for sure stop being friends with him, tell his parents and other students that he’s a weirdo, and he’ll never be happy again.

“What was that?”

“W-what was what?”

“You know!" Tsukasa frowned, probably thinking that Rui is messing with him. “That rod! The long thingy the man pulled out? What did he want to do with that?”

Rui is going to die today for sure. Wait, what? He knew Tsukasa was pretty stupid and sheltered, but he doesn’t know what a penis is? Does he not look down at himself when showering or going to the toilet?

“We should watch further.” Tsukasa suddenly suggested, making Rui gasp and stare at him as Tsukasa reached out back to the DVD. “I want to know what happens next!”

“W-wait! I’ll tell you! Don’t watch," Rui stopped his arms, holding him.

Tsukasa blinked at him and titled his head like a puppy, expecting Rui to do so. To explain what that was.

“…I-it was a penis. You know. The peepee…" Rui explained, not being able to hold eye contact with Tsukasa. “How does Tsukasa-kun not know it? He has it too.”

Before Tsukasa could process what a "penis" is, he made a super confused face. “That was a peepee?”

“…yes?”

Tsukasa furrowed his brows.

“Rui’s lying again!" he accused, breaking his arms out. “My peepee does not look like that at all!”

“Huh…?”

“Even if that was a peepee, why would he pee on a train? That’s prohibited! "You pee in a toilet!" Tsukasa complained. “Rui really thinks I'm that stupid?!”

“I’m not lying! It is a peepee!" Rui argued back, now genuinely confused. “Y-you know, everyone has different types of peepees! That’s why it doesn’t like yours, Tsukasa-kun.”

The only thing he doesn’t want to do is give Tsukasa an insecurity about his size at 11. He heard that a lot of teenage boys feel embarrassed that their penises are too small, but countless research studies showed that a smaller size is more comfortable and is more favored by ladies anyway.

"…Is that so?" Tsukasa mumbled, quieting down and sitting next to Rui, leaning his body weight. “But why was he going to peepee in front of the girl?”

“…He wasn’t going to pee-pee, Tsukasa-kun." Kamishiro explained slowly. He needed to come around this in a very careful way. “It’s called a penis anyway by grown-ups. Boys have penises and girls have vaginas, okay?”

Tsukasa nodded to his words but was visibly still confused.

“You see… girls and boys use these to pee, you’re right. But there’s also another purpose. Touching your penis makes you feel good, and touching it with the girl’s vagina even better.” Rui gulped down. “It’s sort of like a game for grown-ups. You know how massage makes your body feel good?”

“Yeah… so it’s like a massage?” Tsukasa mumbled, staring up at Rui with his big, innocent eyes.

“…Kinda.” Rui bit his tongue. It was not like that at all!

It became quiet for a second. Rui pondered if coming over today was a mistake after all.

“Rui?”

“Yes, Tsukasa-kun?”

Tsukasa awkwardly rubbed his hands.

“Can we continue watching that?”

There was a really loud sound of something breaking in Rui’s mind. Before he could object, Tenma opened his mouth again.

“It’s something that grown-ups don’t tell us, right, Rui? But since I am a future world star and, after all, a big brother… I have to know that kind of stuff first before my siblings or someone younger than me, like Rui," he explained, his cheeks tainted pink. What is happening? Why is this Rui’s life?

“Rui, were you worried that I won’t like this? "That's so silly," he continued, grabbing Rui’s one hand and squeezing it. “I’m a world future star! I can take on anything!”

And that’s how he ended up here.

Two 6th graders, best friends, are sitting shoulder to shoulder watching porn together. Tsukasa’s puppy eyes and begging worked their magic quickly, and Rui gave in, telling Tsukasa that he shouldn’t tell anyone though.

I mean, it’s kind of like in character for boys in puberty like them, right? At least they’re doing it in private, unlike their classmates in school, right?!

Throughout the whole thing, Tsukasa would ask, like, a few questions, like, "What is happening?" or furrow his brows sometimes, but he stayed silent most of the time. The plot of the so-called movie progressed in a regular form: after the man and the girl rubbed each other out on the train, they went to a love hotel. They took a bath together, and Rui noticed the silent “ew” that Tsukasa whispered when the blowjob section started.

“Is he going to put it inside…?" Tsukasa mumbled, almost to himself. Rui nodded back, fidgeting with his sleeves.

“Yeah. That’s the main part of the… process…," he mumbled, as both of them visibly flinched when the screen showed it roughly going inside the girl and her screaming out loud. Tsukasa squeezed his friend with his hand.

“T-That looks painful!”

“…It is, I think,” Rui replied, cringing at himself and the way his face felt disgustingly warm. “But supposedly, the pain is momentary, and after that it feels good.” He hesitated before continuing. “We wouldn’t know, anyway.”

Despite what was happening on screen, Rui really has to applaud Tsukasa on his impressive instance of not getting hard at all. Usually boys their age seeing this would get hard instinctively, even if they don’t understand what is happening, but when Rui looked down at the boy’s shorts, nothing at all peeked out. I respect you, Tsukasa-kun.

The following was quite mundane for Rui and probably shocking for Tsukasa. Nothing really exceptional followed after that, as it was clearly coming to an end (finally). The characters dirty-talked with each other, the girl would scream loudly a little too on purpose, and he wishes he could freely critique their acting if it weren't for the fact that he’s watching porn…

“N-no~ ♡ You can’t, can’t come inside! You’ll get me pregnant!"

“A naughty high school girl like you should get pregnant!”

“N~noo ♡!”

Rui could obviously see the guy was wearing a condom. Who were they trying to fool with that angle? After that, the AMV quickly ended, with a shot of the girl’s vagina in cum. Pretty gross if you asked him, ignoring that he did feel something twitch down there. He desperately ignored it. As the screen faded to black, the only thing in the room was their muted breathing.

He turned to look at Tsukasa, wondering what kind of face he had right now. Maybe ask him what he thought or reply to whatever question he had. But before he could Tsukasa sprung up and quickly got the DVD out of the reader, stretching in the meantime.

“It got so dark already!" Tsukasa exclaimed, his hands at his sides as he smiled his usual wide smile. “We should get ready for bed now, Rui!”

“Huh?” But he was already pulled up as Tsukasa pulled out toiletries from somewhere quickly and handed them to Rui.

“You brought your own pajamas, right?” Kamishiro nodded promptly. “Okay then! I will go prepare the bath, I’ll call you when it’s done!”

Tsukasa disappeared down the hallway before Rui could even gather his thoughts. The bathroom door slid shut, and then Kamishiro was left alone in the pillow fort, clutching his neatly folded pajamas and staring at the blank TV screen like it had personally betrayed him. The screen reflected how unsightly he looked right now.

His face was still warm.

No, burning.

He pressed both hands to his face and groaned quietly into his palms. Why had they watched that of all things? Why did he agree to Tsukasa’s begging? He should’ve said no, and while Tsukasa complained, he promptly set the box on fire and saved him and Tsukasa from the hassle. And more importantly,

Why was Tsukasa acting like absolutely nothing had happened?!

Rui could still picture how close they’d been sitting. He could clearly see or hear that during the watching, Tenma was clearly impressed! The silence afterward. Rui was certain his own expression had looked strange, but Tsukasa had simply jumped up with that bright smile as if nothing unusual had happened at all. Was he not embarrassed at all?? Did Rui underestimate Tsukasa, and he’s like completely resilient to puberty?! Could Tsukasa’s genes be the secret to eternal youth?!

Rui sat down inside the pillow fort and buried his face in one of the blankets.

“This is a nightmare…,” he muttered.

From down the hall came the sound of running water, followed by Tsukasa humming loudly—and completely carefree, apparently. Rui almost felt offended by how unaffected he seemed.

Several minutes passed before the bathroom door slid open.

“Rui!” Tsukasa called cheerfully. “The bath is ready!”

Rui took a deep breath, trying to compose himself. It was just a bath. He would wash up, go to bed, maybe they’d discuss shows with Tsukasa, and this mortifying evening would be over.

He stood, picked up his pajamas, and stepped into the hallway.

Tsukasa was waiting there in a towel draped around his hips, hair slightly damp from steam curling around him. He smiled and grabbed Rui’s wrist before he could say anything.

“Come on, before it gets cold!”

Rui stumbled after him as he connected the dots. His face is definitely red again. “Wait, wait!! Tsukasa-kun, I can go after you, it’s fine—”

“Hm?” Tsukasa blinked, stopping before the bath. “After me? But we’re going in together.”

“…What?”

Tsukasa tilted his head, as if Rui had said something deeply confusing. “Together? That’s normal, isn’t it? The bath is already filled, so it’s more efficient that way! I want us to quickly be done with it—plus, I’ll help you wash your hair! I always take baths with Saki together!”

Rui’s entire body went rigid. He stared at Tsukasa, then at the softly steaming bathroom beyond him, then back at Tsukasa’s completely innocent face. Tsukasa looked genuinely puzzled as to why Rui had suddenly turned bright red. Maybe Rui was too much of an only child to comprehend this.

Rui opened his mouth. Closed it. Opened it again.

“T-Together?!”

Tsukasa laughed, reaching out to tug him inside. “Why are you so surprised? We’re both boys!”

That did not help. That made it infinitely worse.

Rui’s heart was pounding so loudly he was sure Tsukasa could hear it. His mind immediately betrayed him by recalling the scene from the "movie," and he nearly choked on air.

Tsukasa, meanwhile, had already turned back toward the bath, kneeling to test the water temperature with his hand.

“It’s perfect!” he announced proudly. Then he looked over his shoulder at Rui, who was still standing like a statue.

“Rui? Are you coming?”

Rui could only stare at him, completely speechless. Because somehow, impossibly, Tsukasa really was pretending nothing had happened.

And somehow even more impossibly, he seemed to have no idea that Rui was currently one second away from combusting on the spot. Especially when Tsukasa suddenly decided to take off his towel and get in ahead of him. Rui felt his already gaping jaw drop harder before he hurriedly tried to act normal, closing the door of the bathroom.

Tsukasa’s little dick growth finally made sense.

HE DOESN’T HAVE ONE?!!????

“Hurry up, Rui! The water will get cold!” Tsukasa said, splashing the surface lightly with his hand. He was already neck-deep in the water, his cheeks tinted red and a little bit of sweat on his face. Okay, Rui, calm down. So what if he has a vagina? It was wrong of him to assume anyway, so it’s completely his fault. Be normal now.

With a quiet sigh and wobbly hands, he set his clothes aside and carefully stepped into the bath, trying very hard not to make eye contact. He didn’t notice Tsukasa sneaking in a glance.

The water was pleasantly warm, and the moment he sank down in front of his friend, he felt some of the tension leave his shoulders and body. He relaxed his posture and sank further down.

“There, see?” Tsukasa said proudly, as if he had personally invented hot water baths. “Isn’t this nice?”

Rui glanced over. Tsukasa was sitting across from him with his knees pulled up slightly, chin resting on them, looking completely content. His damp hair stuck messily to his forehead, and his cheeks were pink from the heat.

For a moment, Rui forgot all his embarrassment.

“…It is nice,” he admitted quietly.

Tsukasa grinned. “But of course!”

Tsukasa reached out to the corner of the bathtub before pulling out a few rubber duckies.

“These are our rubber duckies! You can choose any to play as - I allow it!”

Rui relaxed, he’s glad Tsukasa is his normal self. Maybe he was worrying about nothing. He reached out to one of the pink-colored ducks, but before he could grab it, the duck’s beak splashed water right in his face.

Tsukasa’s laughter erupted through the bathroom as soon as he saw Rui’s bewildered look. It was so sudden and genuine that Rui could only stare. Tsukasa laughed so hard he nearly slipped, and when he grabbed the side of the tub to steady himself, that only made Rui laugh too.

Soon both of them were giggling, the quiet of the evening completely broken by splashing water and Tsukasa’s dramatic complaints that Rui had “retaliated against a star” after flicking water at him. Of course, as Tsukasa is very notorious about being clean, he volunteered to wash Rui’s hair, back, everything really, himself. At least Rui had the opportunity to nap a bit in the bathtub before his friend’s loud voice pierced through his ears again.

By the time they climbed out, Rui’s earlier awkwardness had faded entirely. As he dried his hair with a towel, Tsukasa looked over and smiled that bright, uncomplicated smile again.

“Next time I’m over at Rui’s house we should take a bath together again! Or I went with my parents and Saki to hot springs once, we should go there too! It’s very relaxing!”

Rui paused, then smiled a little to himself.

Maybe Tsukasa really hadn’t been pretending earlier. Maybe he just had a strange talent for turning even the most embarrassing situations into something simple and warm.

“…Since you’re desperate, sure,” Rui said.

Tsukasa gasped dramatically. “Rude! After I so graciously shared my bath with you!”

And just like that, Rui found himself laughing again as Tsukasa bared his teeth at him while putting on pajamas with a Pegasus design.

~~

“Are you all tucked in, Rui?” Tsukasa whispered as he turned on his night lamp and ran back to their pillow fort. Rui was graciously helped to bed by Tsukasa, accommodating him with two pillows, a plushie, and a blanket.

They were reading a book together that Tsukasa’s parents recently bought him, looking for the main character on each page when Tsukasa realized that it had hit 11 PM, which is dangerously too late for his growing organism, and forced both of them to go to bed.

“Yes, I’m only missing one thing, though.”

“What is it? I’ll bring it! ”Tsukasa sat down next to him.

“Tsukasa-kun.” Rui grinned as he grabbed Tsukasa by the waist and pulled him down into their makeshift bed and hugged him tight-tight.

“Rui, seriously!” Tsukasa whispered, trying to sound stern despite the obvious laughter in his voice. “You can’t just ambush a star like that before bedtime!”

“And yet I did,” Rui murmured, not loosening his grip in the slightest. He buried his face into Tsukasa’s shoulder, warm from the blankets. “Now my final bedtime requirement has been fulfilled.”

Tsukasa huffed, though it came out more like an embarrassed little laugh. “That doesn’t even make sense!”

“It does to me.”

For a moment, Tsukasa stopped wriggling. Rui could feel him go still, probably because he hadn’t expected such a simple answer. The small lamp beside them cast a golden glow inside the fort, making the blankets overhead look like a tiny tent. Outside, the rest of the room was dark and quiet, but inside their little hiding place, everything felt soft and warm. Tsukasa shifted carefully until he was lying properly beside Rui instead of awkwardly half on top of him. He still looked flustered, cheeks faintly pink, but he didn’t move away.

Instead, he crossed his arms and turned his face aside dramatically.

“Well. Since you insisted so much, I suppose I can allow this just for tonight.”

Rui smiled to himself. “How generous.”

“I know.”

They stayed like that, squeezed together under the blanket, the plushie trapped somewhere between them. Tsukasa kept pretending to be annoyed, but after a few minutes his voice grew quieter and sleepier.

“Rui?”

“Hm?”

“Your feet are cold.”

“That’s what you’re worried about?” Rui blinked.

“Yes!” Tsukasa whispered indignantly, shivering. “It’s unpleasant! Why are they so cold?”

Without waiting for an answer, Tsukasa reached down with his own feet and nudged Rui’s, as if trying to warm them up. Rui almost laughed out loud.

“You’re so funny Tsukasa-kun,” Rui said softly.

“Good night,” Tsukasa said quickly, like he suddenly had something else on his mind. Rui smiled in the dark, tightening his arms just a little.

“Good night, Tsukasa-kun.”

Usually, Tsukasa would be dead asleep in under a few minutes, even snoring sometimes if he’s seeing a good dream. But as Rui desperately tries to fall asleep himself, he just can't.

He doesn’t know how long it has been when Tsukasa speaks up again.

“Are you sleeping, Rui?" he whispered quietly, almost as if he were afraid that someone would hear them, even if they were all alone in the house. Rui contemplated his actions before talking back and opening his eyes to see that Tsukasa had been staring at him and his face.

“No.”

Tsukasa blinked, clearly not expecting Rui to answer so quickly.

For a second, neither of them said anything. The pillow fort around them was silent except for the soft rustle of blankets whenever one of them shifted. In the dark, Rui could just barely make out Tsukasa’s eyes, wide and reflective in the moonlight seeping through the cracks.

“…Oh,” Tsukasa said at last, almost awkwardly. “I thought you were asleep already.”

“You were staring rather intensely for someone who thought that.” Rui's smile was faint.

“I was not!” Tsukasa whispered back immediately, then seemed to realize denying it made him sound guiltier. He turned onto his back and pulled the blanket up to his chin. “I was just… making sure you were comfortable.”

Rui hummed, unconvinced but unwilling to tease him too much.

“And? Am I?”

Tsukasa turned his head back toward him. Even in the dim light, Rui could tell he was pouting.

“Yes. You looked comfortable.”

“Then what’s wrong?”

Tsukasa was quiet for a moment.

Rui expected him to brush it off, maybe say nothing was wrong and go back to pretending to sleep. But instead, Tsukasa’s hand fidgeted with the edge of the plushie between them.

“…Nothing’s wrong,” he said softly, then after another pause, “I just had something on my mind…”

That made Rui blink.

“And what is it that’s troubling, world future star?”

Tsukasa was silent so long that Rui thought he might not answer at all. Then he spoke so quietly Rui almost missed it.

“Rui has a penis like that man in the DVD…”

I should’ve pretended to be asleep.

Rui’s breath caught in his own throat, really wanting to be home right now, maybe to do some math, be anywhere but discussing this with Tsukasa. Hearing him even say the word "penis" felt so wrong! How does he even reply?!

Tsukasa laughed softly, like he was embarrassed by his own self and wanted to cover the silence up.

“I thought Rui was lying when he said it’s a peepee." He shifted under the blanket, face half-hidden in the pillow. But you were right. I didn’t know some have them different… so, I’m sorry for calling you a liar, Rui…”

The blanket rustled as Rui moved one hand out from under it, reaching for Tsukasa’s. Their fingers brushed, and Tsukasa froze.

“It’s okay,” Rui said, just as quietly. “I wasn’t mad or upset.”

Tsukasa turned sharply toward him. “Really?”

Rui gave a small nod.

The silence that followed felt different now, lighter somehow, and somehow it made Rui feel cozier as he felt himself relax. Tsukasa’s fingers curled around Rui’s hand hesitantly, as if testing whether he’d pull away. When Rui didn’t, his grip tightened.

Then Tsukasa scooted a little closer.

And then a little more.

Until there was barely any space left between them at all.

Tsukasa’s breathing had almost evened out when, suddenly, he shifted again.

“Rui?” he whispered.

Rui had been just on the edge of sleep, and the sound of his name pulled him right back. He opened one eye to find Tsukasa still awake after all, staring at him from impossibly close in the dark.

“Hm?”

Tsukasa hesitated.

Rui could feel the slight tension in the hand still holding his, like Tsukasa was debating whether to say anything at all. That alone made Rui more awake. Tsukasa was rarely this uncertain.

“…Can I ask you something?”

Rui nodded, though he immediately regretted it when Tsukasa scooted even closer, until their foreheads were nearly touching.

“You can ask.”

Tsukasa looked strangely serious for a moment, his voice dropping to the tiniest whisper.

“About that movie we watched earlier…”

Rui’s entire body went stiff.

He already knew exactly what that meant, and the heat that had faded hours ago came rushing back to his face all at once. He was suddenly very grateful for the darkness hiding his expression.

Tsukasa noticed instantly.

“Wait,” he whispered, sounding startled. “Rui, are you blushing?”

“I’m not.”

“You are! Even in the dark, I can tell!”

Rui turned his face into the pillow, mortified. “Please continue your question or go to sleep.”

Tsukasa made a tiny sound like he was trying not to laugh, which only made Rui more embarrassed.

“I just wanted to ask…” Tsukasa’s voice softened again, and Rui felt the mattress shift as he propped himself up slightly on one elbow.

“Can I see your penis?”

Rui is going to die before even graduating school from a heart attack with this boy. Trapped in a blanket fort at midnight with Tsukasa staring at him and waiting for an answer, it felt a hundred times worse.

“W-why would you want that?!" Rui replied, blushing furiously, and he felt his hands sweat. He only hoped Tsukasa didn’t mind sweaty arms.

“I never saw one before. And today I saw two. One on TV and yours," the words coming out of his mouth felt like absolute nonsense of words tied together. “I didn’t really get to see Rui’s while we were bathing….”

“So, I’m really curious, Rui…”

Tsukasa moved closer to Rui, dangerously close. His breath was gone.

Rui’s brain was still trying to catch up.

“Show… you?”

Tsukasa made a muffled, mortified noise from inside the blanket. Tsukasa didn’t even know about this kind of stuff, or that a penis exists, until a few hours ago. And somehow, Tsukasa had asked it with such startling sincerity that Rui could tell he wasn’t joking.

Rui was suddenly very aware of how close they already were, sharing one pillow fort, one blanket, one tiny pocket of warm air.

Rui swallowed.

“Tsukasa-kun, you know, that’s not something that you go around showing to everyone…”

He immediately nodded in agreement to his words. “But Rui and I are best friends, right? You can trust me!”

“And, if you do it, I'll show my pe-v-vagina too!” Tsukasa whispered in a panic. “So it’s fair!!! To both of us!!”

Tsukasa was staring at him, eyes wide in the dark, looking almost as shocked as Rui felt, like he hadn’t meant to say it out loud, but he did. His face was bright red. See Tsukasa’s pussy? His head is going around in circles, please slow down!

Another silence fell, thick and fluttering and impossible to escape. Then the blonde slowly brought the blanket to his face and looked at his knees. His expression had lost some of its panic, replaced by something hesitant but earnest.

“It’s okay if you don’t want to,” he whispered. “I just…that, maybe…Mnm…"

Rui’s chest tightened.

His second weakness after vegetables is Tsukasa being obviously upset and wanting something but pretending he’s not. It happens too often, like when Rui brings sweets from home and Tsukasa is pretending to not care, or when they’re reading a book by roles and Rui gets the “better role to read." Tsukasa won’t say it out loud, but his face is so obvious that Rui has to suggest switching or sharing himself.

He stared at Tsukasa for a long moment, at his nervous eyes and pink cheeks and the way he was trying to act brave even though he was clearly one second away from hiding under the blanket forever.

Rui let out the softest sigh.

“You ask impossible things so casually.”

Tsukasa opened his mouth to apologize again, but Rui gently got out of the covers, and his hands went to his pajama pants. That shut him up instantly.

Rui was blushing just as badly, if not worse, but he pulled down his shorts as fast as he could think too hard about it. He paused only for a second, enough time for Tsukasa to take the tossed-aside shorts and quickly fold them before Kamishiro’s fingers would grip his underpants and pull them down too. The whole time he could feel Tsukasa burn a hole in him, or more specifically, in the spot between his legs.

Rui wouldn’t say his dick is big, considering it’s still going to grow. Especially compared to the man from the movie they watched, but to be honest, even that guy’s wasn’t even that big. He saw bigger things. But he guessed, to Tsukasa, seeing something like that would be impressive, anyway. Plus, he’s not going to discredit himself fully, his penis did start growing a bit of time ago, with him taking measurements every few months to keep track.

The way cold air suddenly hit his lower part made him blush more. Looking at it himself like this is embarrassing, no matter how much he saw it before.

As his parents are both very knowledgeable, they had him circumcised when he was still a baby, so unlike the majority of boys their age, his glans is fully visible. There was some hair starting to grow in down there, but not a full-on bush yet.

“So it looks like that…" Tsukasa said, in some kind of amusement, looking down at it. He wonders what Tsukasa thinks. As far as he knows, girls find penises to be a bit freaky and scary at the first stages of puberty. Tsukasa is not a girl, but considering he, who grew up with his sister only, never saw a dick before, he may have a similar reaction.

“Can I touch it?”

Rui flinched like an abuse victim. Before he could reply, Tsukasa had already moved closer, and his finger experimentally touched it. Rui’s penis, embarrassingly, twitched in reply to him.

“W-wait, Tsukasa-kun…!”

“I think she did this…" Tsukasa mumbled to himself, ignoring how much of an embarrassing mess his friend has become. Tsukasa poked the head a few more times before he wrapped his tiny palm around it.

“T-tsukasa-kun!”

“Rui?” He looked up, his left palm still holding it. “Does it not feel good?”

“Tsukasa-kun, we shouldn't—" He choked on his words when he gave it an experimental jerk. “Tsukasa-kun, please!”

“I just want to see something, okay, Rui?”

There was another jerk that wasn’t experimental anymore. Rui bit his tongue. Great, he’s going to get hard in front of his best friend and embarrass himself. It was dry, sort of uncomfortable, but that was stimulating him even more. And then, Tsukasa’s face was dangerously close to it.

He swallows deep. He admits that one time, or maybe a few more, he had this kind of fantasy of Tsukasa’s chubby cheeks and big eyes on the same level as his dick, but that is something you take to your grave, not actually recreate! Even then, it’s not like he’s some pervert like other boys, he only thought of things like these when nature called him! This is the worst-

“A-ah! I did it!”

He heard a happy voice and finally opened his eyes. Tsukasa was smiling proudly to himself because he got Rui erect.

“T-Tsukasa-kun….”

“I’m sorry, Rui! I wanted to see how that girl got the penis to stand up,” Tsukasa explained, pushing himself up on his elbows. “Why does it even do that? Mine doesn’t stand up like this.”

Of course, he thinks. Of course Tsukasa would rile him up and then leave him hanging like that. It’s part of his charm, kinda. Rui needs to gather his breath first before replying. Tsukasa patiently waited for him. He nodded.

"It's…it's called an e-erection. The penis hardens and enlarges due to… sexual arousal. Excited Rui figured that explaining in full detail that your muscles relax, allowing the blood flow to increase in the penis.

“Oh, it did get hard and big too, not just standing!” Tsukasa said, making Rui hold on with a whimper because he decided to touch it again. The dick twitches in response to Tsukasa, making him smile a little bit. Sadist.

“Well, thanks, Rui!" Tsukasa sat back up straight, pulling the blanket up. “We can go back to sleep now. Thanks again!”

Rui didn’t even have time to react before Tsukasa fell into the pillows again, closing his eyes with a satisfied smile. What? This is it? Tsukasa is just going to leave him like that, half naked and his dick hard?

Rui may have been able to think better when he had a clear head. But now that his best friend had jerked him off and just left him to deal with an erection himself… it may have influenced his thinking a bit.

“Tsukasa-kun…” He furrowed his brows, and Tsukasa only hummed in reply while there was some shuffling.

“Rui?”

With Kamishiro's both hands beside his head, he held himself above him, leaving only a sliver of space between their bodies. He felt like he was caged in right now.

“Tsukasa-kun is so cruel." Rui was breathing heavily, and Tsukasa swears he never saw his classmate like that, even after the hardest exercises during P.E. class.

“Didn’t Tsukasa-kun promise me something back if I showed him my penis?”

Tsukasa visibly got nervous. He thought Rui forgot about it. He brought one hand to fiddle with his star-printed pajamas.

“World future stars don’t lie to their friends, right?”

Tsukasa’s face tensed up.

“Right?”

~~

“Rui, t-this is…a bit."

“Didn’t Tsukasa-kun do the same to me?”

After Rui had graciously helped Tsukasa with the task of taking off his pants and panties, he was blessed with a beautiful sight of a pussy. The boy, who was sitting like a museum exhibition, was propped against many of the pillows so he was in a sort of lying down-but-still-sitting position so he could both see what Rui’s doing and Rui could have easier access.

“I’ve never seen a vagina up close either, you know,” Rui whispered, placing both of his hands on the sides of his thighs and pushing them to the sides. “I’m curious.”

There was a loud gulp, but Tsukasa nodded. After all, he promised. And his mom said that if you lie, your nose grows, so he shouldn’t do that ever. He remembers his mom telling him to never show this side of him to anyone, but he can always trust his bestest friend ever, right?

Rui took in every detail of the sight in front of him. Tsukasa visibly hasn’t started physical puberty changes, like his period starting or pubic hair or something like that, but looking at the wet discharge in Tsukasa’s panties after jerking him off, he’s not that far behind if he feels sexual attraction, even if it’s subconscious.

Letting go of his right thigh, Kamishiro brought his palm to the pussy. Even just putting his hand close, he could feel warmth radiating from it.

"Wow…" he mumbled to himself and pulled apart the outer labia to reveal the main star of the show.

“Hghn…”

His vulva was a pretty, pinkish color. Pulling apart the lips like that made a little wet sound, and Rui could feel something sticky on himself, either discharge or just Tsukasa’s wetness after watching that movie or seeing Rui’s dick. His clitoris was pretty big considering the fact none of the other major factors appeared yet. However, he hasn’t checked one thing…

“Tsukasa-kun, can I ask you to do something else too?" he asked, bringing his head up to meet with his eyes.

“W-what is it?”

“Can I take off your shirt too? Or, if you think you’ll get cold, just lift it up to your head?”

“My shirt? "Why?" Tsukasa asked, more confused than embarrassed. Tsukasa usually wore undershirts with his uniform, so Rui needed to prove something.

“I want to see your chest. Nipples, for that matter, is that okay? Rui explained, pointing to where they are supposed to be. “They can feel good too. You know, when mommies get babies, they feed them with their milk, through the chest?”

“I know that," he replied, making an offensive face, probably ready to complain about why Rui thinks he’s stupid but deciding to bite his tongue. “Okay, you can look. But I don’t have any milk there, just so you know!”

Tsukasa obliged, hurriedly undoing the buttons on his pajamas and then letting it fall to his arms at his sides.

“Pink too…”

“Hm?!”

Tsukasa had some sort of boob growth too, he makes notice. It’s barely visible, but compared to others, you can see Tsukasa’s nipples sticking out a bit and hardening, probably due to suddenly being exposed to cold air.

“Cute… Tsukasa-kun, I can touch them, right?” He asked, but his right palm was already brushing over the nipple.

"S-sure—Mngh!"

Tsukasa whimpered too loudly for his own standards as he felt Rui’s soft hands grab his right nipple. He gave it a couple experimental squeezes and pulls.

“It feels weird…” His face contorted in a weird expression as Rui opted to instead cup the tit.

“Makes sense. Feeling good from the nipples is said to be more of a thing you need to develop, rather than something natural…”

“What?”

“Well, anyway,” he let go of it as his hand travels further down slowly as Tsukasa squirms in embarrassment.

A faint flush creeps up his neck, the usual confident grin wavering as he stammers, fingers fidgeting. Rui spreads his labia again, and this time doesn’t wait to touch it with his fingers, sliding it down slowly.

Distantly, Rui thinks that he should stop. That after this Tsukasa is going to be traumatized, scared, or hate him forever, or that at very least it’s too soon for both of them to be doing this, that he and Tsukasa are both not ready, but his thoughts are cut short when Tsukasa whimpers from his arms and he can feel the wetness of it.

“Mnghm…”

“Tsukasa-kun, did you know there are two holes in your pussy? ”His voice rang out in the room, and Tsukasa wanted to question him, but the really weird feeling of frequency between his parts and Rui’s fingers had his mouth closed against his will.

“This one,” Tsukasa gasped when he pressed down somewhere in the middle, feeling his breath quicken. A pleased smirk spreads across Rui's face, going unseen by Tsukasa. “This one is where you pee out of.”

“R-rui…” He breathes out and brings a plushie to hold onto. His legs twitch.

“And this is the one,”

Tsukasa felt something down there, something that felt completely foreign, probing at something that shouldn’t be probed. He shuddered, not knowing what to hold on to.

“A-Aah!!”

Rui slipped a fingertip right inside the virginal heat of his pussy. Tsukasa cries and doesn’t know how to react, feeling something foreign in him, moving and stimulating him. “This is where a cock does in, okay? But before putting it in, I have to stretch it out with my finger so it won’t be too painful for Tsukasa-kun.”

Rui’s voice tickles something inside him. When did it get like that? He swears Rui didn’t sound like that before, but he remembers someone telling him that when you grow up, your voice gets lower. Tsukasa can only whimper and shift uncomfortably.

“Can I continue, Tsukasa-kun?" he asks a meaningless question as he already pushes in his pointer deeper, and Tsukasa reels from it, it felt uncomfortable, tingly, and like something was pressing on him all at once. Choked-out moans are all he can manage.

“Rui… T-too much… hah… Stop….”

Something inside of him whispers for Rui to ignore him and shove a second finger in. Million scenarios of them recreating the movie they saw fly through his head.

“…Okay… Sorry.”

He knows better. Slowly, his finger is free of the tight embrace of his pussy, and Rui stares at the wet slick on his finger before wiping it off on his leg. He reaches out to hold Tsukasa by his shoulders. “Are you okay?”

Tsukasa breathes heavily, not meeting his eyes. His still exposed chest goes up and down, and Rui can’t think of anything better than going to brush away his wet bangs and pet him. Tsukasa finally looks up, striking a weak smile and wiping away drool with a fist.

“I’m okay!” He breathed out, showing his teeth to Rui. He smiled faintly before removing himself.

“I’m sorry for doing that,” Rui added quickly, the words tumbling out before Tsukasa could say anything.

He shifted back a little, finally putting some space between them, but the heat of his body still lingered, it being close enough that Tsukasa could swear he felt it pressed against his skin even after Rui moved away. Rui’s gaze dropped to the floor, usually so steady and unreadable, now strangely uncharacteristic in its avoidance.

Tsukasa sat frozen where he was, chest still rising and falling hard from the surprise of it all. The image of Rui above him: hands braced on either side of his head, trapping him so easily… It refused to leave his mind and probably won’t anytime soon. His face burned hotter at the memory, and something inside of him twisted. Rui let out a nervous laugh, though it sounded thin.

“I didn’t mean to do that… I acted without thinking…” He trailed off, fingers tightening against his own sleeve until his knuckles went white. “It’s fine if you don’t want to be friends anymore…”

For a moment, Tsukasa could only stare.

The words hit him so unexpectedly that his mind blanked. Of all the things Rui could have said, that was the last thing he had imagined. His chest, already pounding from the hot moments before, twisted sharply.

“W-What?” Tsukasa blurted out, moving closer to him without realizing it. “Why would you even say that?!”

Rui looked away, his smile faint and brittle, like he was trying to make it seem like a joke and failing. “I made you uncomfortable, didn’t I? You looked frightened. I thought… perhaps I crossed a line.”

Tsukasa’s mouth opened, then shut. He thought back to how he must have looked… Did his face burn back then? Was he really that unable to say anything of importance? From the outside, it probably had looked awful. Like he wanted Rui gone… But that wasn’t it. That wasn’t it at all! It felt good!

His face turned even redder as the realization settled in, but the thought of Rui actually believing he’d throw away their friendship over that made something in him lurch.

“Don’t be ridiculous!” Tsukasa snapped, louder than he intended, grabbing his friend’s hands.

Rui blinked, clearly startled. Tsukasa immediately regretted how harsh it sounded, but he pushed through, words spilling out in a rush.

“I was surprised, that’s all! You just… you suddenly got so close, and anyone would’ve been caught off guard! That doesn’t mean I hate you!”

Rui stared at him in silence, and Tsukasa could feel his ears burning. He hated how flustered he sounded, but he couldn’t stop now.

“You’re my best friend,” Tsukasa said, his voice dropping, softer this time. “So don’t say stupid things like that.”

For the first time since pulling away, Rui looked genuinely taken aback. His fingers loosened around his sleeve, and the tense line of his shoulders eased ever so slightly.

Then he smiled.

“…I’m glad,” Rui said softly.

And somehow, hearing those simple words made Tsukasa’s heart beat even harder than before. Now that they’re being honest, Tsukasa has to be completely honest! Completely means…

"A-and!" Tsukasa started, ignoring how both of them were having this very serious conversation half naked, Rui’s cock still in full view and his pussy too.

“I-It actually felt really good, Rui!!!”

That was definitely too loud for the time it was and what situation they were in. His friend’s eyes widened, color spreading everywhere, from his face to his ears.

“W-when Rui pulled out of my… Pussy…” Tsukasa had shifted to almost being in his lap, and the continued hand-holding was making him dizzy.

Tsukasa’s small hands took his hand and guided it to the star’s stomach.

“It feels empty here now without Rui.”

“So can we continue?”

Rui didn’t reply with anything back before Rui’s lips came in contact with Tsukasa’s. Surprised at first but slowly melting in and opening his mouth for Rui to explore with his mouth, Tsukasa moaned into it, wrapping his arms around his neck and trying his best to learn on the spot and kiss him back.

Tsukasa barely had time to breathe before Rui pulled him closer again, one hand gripping the back of his pajamas tight enough to wrinkle the fabric. Every time they parted, it only lasted a second before one of them closed the distance again. It was messy and clumsy and overwhelming in a way Tsukasa couldn’t untangle. His face felt hot. Rui’s breathing was uneven against his skin. He never felt like this, nor did he know he even could feel like this.

“You’re unfair,” Rui whispered, sounding almost frustrated, before kissing him again.

“Mmghn! ♡”

He broke away with a moan when he felt hands explore his pussy again, this time teasing his clit as Tsukasa arched his back into it. Rui doesn’t wait for any kind of word from him before he slips in two fingers at once, setting a pace and pressing down on the clit.

“R-Rui?!”

“Tsukasa-kun, sh-shh!” His mouth flew over his, breath warm against his. His face was burning, and Tenma could only mewl into the kiss as the friction down there burned hot against him. He felt overwhelmed, so overwhelmed, and the way Rui was handling him made it all the harder to think. Tsukasa could hear his heart pounding in his ears, and he hoped his friend didn’t.

“J-just trust me, okay?”

Rui felt his head fill with blood. Tsukasa’s tight walls were clenching down hard on his fingers, and his mouth salivated thinking about putting his cock inside. Tsukasa broke away for his head to roll back, his mouth wide but not making any meaningful sounds but pretty squeals, drool dripping down his chin and getting all over the blankets. Rui settled on instead kissing down his chin to the neckbones, carefully sucking on the skin when he felt Tsukasa grab his wrist.

“R-rui, Rui-Rui-Rui… I-I’m… I’m going to pee myself, stop-st…!" The blond boy stared up at him with tear-clouded eyes, sparkling against the dim light of the moonlight outside and the still-turned-on warm light of a night light. He was shaking, tongue lolling out on its own.

“I-it’s okay!" Rui replied, a little too excitedly, smiling wide at him. He only quickened his moves, not even realizing how sore he’s gotten or that his hand is soaked in various fluids.

“N-no, R-rui! I-I really got to…!" He shook his head desperately, but the words died down in his throat as his orgasm washed over him, opting instead to squeal, his eyes rolling back, vision burning white, and something leaking out of him. Seeing the beautiful sight in front of him, Rui only continued to leisurely pump into him, who was still clenching around his fingers and shaking from the aftermath. He’d love to sit here and overstimulate him until he’s nothing but a short mess of whines and cries, like some kind of obsessive maniac, but when Tsukasa completely stops moving, he decides that it’s good enough. He’ll do it next time.

As he pulled out, he saw Tsukasa’s velvety walls were left clenching around nothing, completely empty. He had to hold back the urge to shove himself in, much deeper than he could ever be.

“Are you okay, Tsukasa-kun?”

A teary-eyed, sinful, and warped face of his best friend replied to him. He barely lifted his head up to reply, and Rui felt a seed plant in his head that will probably impact his life forever now. He was the first person ever to see the world's future like that, and something greedy inside of him hoped he was the first one and the last one.

“M-mhm… L-Lui…” His relaxed smile shone at him. He was going to ask or suggest to Tsukasa if he would like a drink of water or something else, but Tenma had other plans.

"So good…♡”

It felt so good. Tsukasa felt an itch burning deep inside of him, one he wanted to scratch so badly, and only Rui could help him with it. With his corrupted mind, he couldn’t think of anything but wanting more, to beg for more. His legs are spread wider, and he sighs.

“M-more… Rui. ♡ I want, I want more…♡”

He grabs clumsily at his hands, trying to pull him back into a sloppy kiss, and Rui doesn't protest much - only for a second is he shocked before he props himself right in between him again and gives him what he wants. He doesn’t have to be asked twice, especially when his cock is throbbing for it too.

“Tsukasa-kun… Tsukasa-kun, Tsukasa-kun, Tsukasa-kun…!" he repeats his name like a prayer in between their kisses, which at this point look more like sucking and hitting their tongues together. A long line of saliva connected them as Rui pulled back to help Tsukasa lay down properly and pull away the hanging sides of his shirt.

“R-Rui, M-more…!” He shuddered underneath him, the cold air of the night not having any effect on him anymore. It was unbearably hot, too hot, and only Rui could help him get rid of it. Rui lavished in biting down on his collarbones, slowly going down to suck his nipples and then lick a stripe down his soft stomach.

“Tsukasa-kun,” he whispered against his hot pussy, the boy shivering from the feeling of Rui’s hot breath against him. He whines in dissatisfaction, reaching desperately for Rui, ignoring whatever concepts shame and embarrassment are.

“I want to put it in. Please-please-please? Kamishiro was at his limit himself, grabbing Tsukasa’s thighs with a too-rough and hungry desire. He swiftly lines himself up against Tsukasa’s pussy, almost as if showing off his size to Tsukasa. Like a warning as to what is to come, one last chance to stop this and never speak of this again. Rui would move schools, never leave his house again, and spend the rest of his miserable life recreating this moment.

"Yes♡…"

He hears a gasp as something starts rubbing against him. Supporting himself on his elbows, Tsukasa is desperately trying to rub one out, coating Rui’s cock in his generous amounts of slick shaking.

“R-Rui, I told you before to not tease me…♡” He tries bucking in, catching the tip where it burns inside, but ultimately, he doesn’t know how to. His pathetic attempts for it to slip in, or to grab Rui’s hands and kiss him, fail miserably, and he can only whine about it. He pauses.

“L-Lui… I need you… in-inside, please!”

Rui felt something inside of him blow up, followed by countless pieces of confetti blowing through everywhere and water effects splashing everywhere. Tsukasa was begging him to fuck him. His restraint is nonexistent now, gulping audibly with a crazed look. How can a director like him deny his star?

It takes a lot more than just willpower for you to just barge in, take what he wants, and fuck the living soul out of him, holding himself back with all the knowledge he read online that the first time is very painful for the receiver and that in the future, when they’re older, he will be able to take him as rough as he wants. But for now, he supports himself as he slowly stills, Tsukasa biting down on his lips as he tries to grow used to the intrusion.

“T-Tsukasa-kun… Ngh…" He’s barely breathing with how hot it is, sweating through his shirt. It feels good, impossibly so. Tsukasa’s pussy was nothing short of amazing, his walls hugging his cock in a perfect way that he never felt before just jerking off - it was so tight. It makes sense with their age. A sick part of Rui wanted to grin and laugh with the knowledge that he’s the first person ever to be inside of this world future star quality of a pussy. Another part of him was screaming at him for tainting the World Future Star with his own dirty self, with no condom too, but when the boy moans and mewls under him he quickly forgets.

He holds his thighs in a bruising grip as he bottoms out. “Ngh… That’s… That’s good, Tsukasa-kun."

Tsukasa sobs and nods in response to his words. It hurt, unbearably so, but something about being full again and being full of Rui made the pain bearable - the pain felt good. He tenses up when he feels that Rui’s fully inside of him, and every little movement makes his cock drag against his walls and hit every possible nerve there is.

When Rui takes his silence and evened-out breathing as a sign that it’s okay now, he starts moving. Tsukasa’s eyes shot open, and he had to bite onto the animal plushie that was nearby to hold in a scream as Rui’s cock travels all the way back, the head stopping at the edge. His screams are muffled before Rui decides to move back in, much deeper this time. The tip of his cock was kissing his cervix, knocking on his womb, and he was so, so deep. Rui’s eyes are clouded as he observes every face expression Tsukasa graces him with, trying to imprint each one in his mind for a lifetime.

“Hah… Tsukasa-kun…”

When he thrusts again, this time faster and harder, Tsukasa can’t hold back a moan as his head falls back again. It hit a particular sensitive spot, one that made Tsukasa see white flashes in front of his eyes. Rui gasps in amazement and bewilderment. He knows which way to angle his moves now.

“Tsu-Tsukasa-kun is so amazing."

The compliments fly past his head as the warmth in his stomach starts to grow when Rui begins to move his hips faster. He’s an incoherent mess of moans, all kinds of bodily fluids and tears, his mouth hanging open, wanting to tell his partner something, but nothing comes out. He can’t do anything but lie there and take whatever Rui gives him, which is otherworldly ecstasy.

“Ah~ ♡! Mgh... so good…! Ru… Rui! P-please, keep doing it~ ♡ There ♡!!”

Rui keeps fucking Tsukasa desperately, caressing the bruises his hands left on his hips, moving him up and down on his cock as he hits the entrance of his womb. He groans, the absolutely fucked-out expression that Tsukasa had driving him insane. His thrusts become messy and crazed as he smiles at the delicate tears escaping his eyes.

“Ts-tsukasa-kun ♡..."

Both of their breaths come out in short parts. Rui loses control and any kind of rhythm fucking away into him, growing greedy like he’s a spoiled child as he feels his own climax approach him. And the way Tsukasa’s warm walls clench around him can only mean that he’s close too.

Tsukasa squeals and mewls, and when Rui notices that his fingers are fidgety, like he doesn’t know what to do with them, he leans down for him to grab his neck. Tsukasa does so immediately, pulling him closer to lick at Rui’s lips with his kittenish licks, still unsure of how to kiss properly. Rui laughs with that crazed look, licking Tsukasa’s escaped drool before kissing him.

“L-Lui! Ha-Nghm ♡!! M-more!! I’m… I’m gonna…!" Kamishiro grins, licking his lips one more time before diving to lick Tsukasa’s ears, speeding up at the same time.

“Hey, Tsukasa-kun, it’s okay if I come inside of you, r-right?” The words come out before he thinks about them, but his own words make him shiver in delight. And his dick twitched in interest too.

“It’s o-okay, right? I’ll put a baby in Tsukasa-kun here, and we’ll get married. We’ll be a fa-family!" Tsukasa reels loudly at that, and it almost pushes him over the limit, but he holds himself back. Thought of getting Tsukasa pregnant with his own cum, and his baby got his head going in circles. Tsukasa seems to have the same reaction.

“I-it’s okay~ ♡!…. Please, please, please…♡! I—wuv you, R-Rui ~♡!!”

He screams when he feels the thread snap inside of him, pulling Rui alongside him as his walls clamp down tightly. A gushing wave of cum spurts deep inside.

making him moan and shiver from the feeling. Both barely can breathe. His mind is peacefully blank, eyes unfocused on the ceiling, and he can hear his heartbeat and Rui’s heartbeat beat in unison at the satisfaction.

When Rui catches his breath finally, he can finally admire Tsukasa’s blissed-out face. Not taking his eyes off him, Rui begrudgingly pulls his dick out of Tsukasa, something going off in his mind again when a mix of slickness, blood, and cum spills out of his pink pussy. He wants to be like the cool grown-ups who take care of everything, but there’s only so much his small body can do, and he collapses over Tsukasa's body, tired. They both lay like that for a few minutes.

When Tsukasa evens out his breath, he decides to pet Rui’s hair, brushing his wet bangs back, to offer some comfort.

“Are you okay, Rui?" he asks, with such a concerned tone that Rui feels bad.

“Y-yes, I’m okay. But you—T-Tsukasa-kun, are you okay?”

Rui finally pushes himself off the boy and quickly looks over his face, searching for any sign of injury. Sitting beside him now, he uses his clean hand to inspect the damage more carefully, panic written all over his expression.

“That must’ve hurt, right?! I-I’m sorry, Tsukasa—let's get you into a bath—!”

“Rui!”

Tsukasa practically shouts his name just to stop him. Propping himself up onto his elbows, he reaches over and flicks Rui on the forehead. Rui lets out a startled gasp, immediately bringing a hand up to the spot with an offended frown.

“Rui is stupid,” Tsukasa says with a laugh. Rui stares at him blankly for a second, clearly caught off guard by the reaction.

“That’s very rude after I hurt you.”

“You did not hurt me!” Tsukasa shoots back immediately. “You’re acting like I’ve suffered some life-ending injury!”

“But you were bleeding…” Rui mutters, eyes dropping guiltily. Even now, he still looks shaken, shoulders tense and stiff with worry. “I did my research before, everyone said that it’s very painful the first time, especially with a guy who sucks. I didn’t mean to hurt you... I got distracted…”

The irritation in Tsukasa’s face softens almost instantly. With a small sigh, he reaches up and grabs Rui’s wrist before he can retreat any further into himself.

“You’re way too dramatic sometimes.”

Rui blinks at him. “Sometimes?”

“Okay, all the time.”

A weak laugh finally slips out of Rui, and Tsukasa grins in victory at the sound. The heavy tension from moments ago starts to melt away.

“There,” Tsukasa says proudly. “That’s better. You looked like you were about to attend my funeral.”

“I was considering what flowers to bring.”

“Rui!”

This time Rui laughs properly, shoulders shaking as Tsukasa groans in disbelief beside him. Even so, Tsukasa doesn’t let go of his wrist. His thumb absentmindedly brushes against Rui’s skin, grounding him there.

“Then,” Rui speaks after a moment, his voice quieter now. “Did it feel good?”

Tsukasa pauses, caught off guard by how sincere he sounds. His face warms a little before he looks away with a huff.

“…Yes. It did.”

“I see,” he murmurs back softly.

The room falls quiet after that. The earlier panic had faded completely now, leaving only the sound of their breathing.

Tsukasa risks glancing over at him, only to find Rui already looking. Their eyes meet for a brief second before Rui smiles, small and relieved, so different from his usual mischievous grin that it catches Tsukasa completely off guard.

“…What?” Tsukasa mutters, suddenly self-conscious, cheeks red.

“Nothing,” Rui says, though the smile on his face says otherwise. “I’m simply happy.”

“H-Happy about what?”

“That Tsukasa-kun enjoyed having sex with me. He even allowed me to put a baby in him.”

“A-ARGH?! R-Rui, are you serious that there’s a baby inside of me now?! But what about school?!?!?” Tsukasa panics, getting up to grab at Rui’s shoulders as the latter is laughing. He felt the cum inside of him move with his movements and shuddered.

“I’m joking. The chances that it catches are very low. Plus, Tsukasa-kun hasn’t had his period yet, right?” Rui calms him down, letting him by the head.

“My what?”

“Forget anything I said." Rui shook his arm in front of his face and yawned. “Anyway, Tsukasa-kun, we should really take a bath again. As much as sex is fun, sexual acts without protection and such can be dangerous if not washed and disinfected right after…”

"Dangerous?" Tsukasa tilts his head before noticing something that catches his eyes.

“Yeah, like, Tsukasa-kun could get sick. You wouldn’t want to get sick and infect your parents or sister, right—AURGHG?" Rui jumps in his place.

Tsukasa has gone down on him, ass up in the air, as he carefully pressed a kiss to Rui’s soft tip. Still leaking the leftovers after his orgasm, the next lock was much more bold, licking off all of the leftover fluid off of him.

"Ts-Ts-Tsukasa-kun!" By the time Rui can pull him back up, Tsukasa is already mouth-full of whatever he licked. “Y-you shouldn’t do that! I-it’s disgusting and tastes bad—"

"Ah~♡"

Tsukasa opens his mouth with a pop of the lips, showing Rui that his mouth is empty.

“Rui, I drank it all♡." Tsukasa was smiling at him, with the most evil, erotic, debauched, and perverted face expression he ever saw in his life. “That woman in the movie drank the man’s cum too, so I thought I should- R-Rui?!”

His heart lurched hard enough to hurt. Dangerous, he thought immediately. That expression was genuinely dangerous.

Rui looked away for a second, pinching the bridge of his nose as though that would somehow help him recover. It didn’t. Every time he looked back, Tsukasa was still there, still unbearably adorable and erotic at the same time.

“I need you to understand,” Rui muttered, voice strained, “that I am currently exercising tremendous self-control.”

“Huh? What is Rui talking about?”

“L-let’s just go get a bath, Tsukasa-kun!”

~~

That night, after finally managing to clean themselves up properly (and, unfortunately, having to wash a few pillows and blankets along the way), the two of them collapsed back into bed completely exhausted. Neither of them had the energy left to talk or do anything anymore. Tsukasa barely made it under the covers before Rui wrapped an arm around his waist and pulled him close again, as though letting go for too long had already been unbearable.

“Rui, you’re hot,” Tsukasa mumbled sleepily, though there was no real protest behind it.

“Mhm,” Rui answered without shame, burying his face into Tsukasa’s shoulder. His damp hair brushed softly against Tsukasa’s neck, earning a tired shiver from him. “Tsukasa-kun is soft."

Tsukasa let out a weak groan but shifted closer anyway until their legs tangled together beneath the blankets. For a while, Rui simply held him there, thumb lazily tracing circles against Tsukasa’s side. Tsukasa’s breathing evened out first. Rui noticed immediately, of course.

A small smile tugged at his lips as he looked down at the boy curled against him, half-hidden beneath the blankets with messy hair falling into his eyes. Even asleep, Tsukasa unconsciously leaned closer whenever Rui loosened his hold, chasing warmth without realizing it.

So cute, he pulled him closer, pressing one last sleepy kiss against his forehead before finally letting his own eyes fall shut too.
