Summary
“You’re always so nice to me, and I wanted to make it up to you, so I filled the apartment with stuff you love. It’s Yuchi day!” Kyo threw his hands up, motioning to the decor with a smile.
[...] Yuchi walked past a printed-out photo of sukekiyo taped to the wall, dodging the dogs dancing around his feet, and stared at one of Kyo’s old exhibition photoshoot pictures pasted near it. Kyo had also printed and delicately cut out a photo of Yuchi’s favorite bass and stuck it up with washi tape and heart stickers. “Things I love, huh?”
Or: Kyo surprises Yuchi with a special day just for him.

Summary
He lost himself in the pushing and pulling inside her, forgetting for a while that the tattooed body he was inside was his own. As she flipped her pigtails over her shoulder and looked at him, he saw straight into his own pleasure-drunk face, and he saw how much he loved to be fucked like this: eyes rolled, mouth open and panting, sweat slicked and pink. He clapped a hand over her mouth when she started to moan, only for her to start squealing against his palm in delight.
With every cry, with every touch of herself over her bra, every feminine utterance of their name, each time she spread her legs and whined submissively for him, he grew more disgusted, thrusting into her harder. He wanted her to hate it, the way he hated it, but she only smiled at him and begged for more.

Summary
The hall of people were bound together by a love of decadent perversion, a shared understanding passing between performer and viewer that this was something intimate and debauched. The audience were sometimes an unthinking mass to him, mannequins set up just so to watch and not interact. But as he looked on at them today, a strange aura of sin whirled in the air, and there was a choking miasma of sex as they sat in wait.
He bent low to the stage, flashing the audience his tight shorts beneath his skirt. He wished he were wearing his leather detailed panties, showing off the stiffness that distorted the corseted design on the front in such a pretty way. He wished they knew, he wished they would see the evidence of his arousal, spurred on by their quiet watchfulness. He wished they knew all of his sinfulness, and all of Yuchi’s as well. As he sang to them his debased words about sex and death and love, he felt the self-indulgence swell within him.
Or: For Kyo's birthday, Kyo and Yuchi decide to live out an exhibitionist fantasy they have during the second day of the Yume Otogi Kyou lives.

Summary
Yuchi never knew if she ever believed in their marriage or not. He did, at least at first. She would laugh in his face and say she never would be so stupid, that she knew all along, but he wondered if she was just as devastated when she realized it was always a sham.
Yuchi felt lucky that the woman he married was also his best friend. Everyone said that’s how it should be. But as they lived like roommates, something felt viscerally wrong.
He knew he should have felt something more when they made love. That phrase—“making love”—felt so odd to him. He loved her without ever touching her, and yet as they laid bare for each other, it all felt hollow.
Or: Between a failed marriage, an obsession with his bandmate, and the beginning acceptance of his sexuality, Yuchi faces difficult realizations in the wake of Sukekiyo releasing Anima.

Summary
Neither were chasing their climaxes, only wanting to continue feeling each other in an endless, pleasant wash of pleasure. They took turns moving into each other, lazily rolling their hips to keep the friction up enough to prolong what they knew they could achieve within seconds if either really wanted. But this is what they wanted: to feel each other, for the adrenaline to build up enough for the words they were too self conscious of to speak at any other time to come to the surface, to keep collapsing on each other in exhaustion and feeling their hearts beating against one another. Years of repression sloughed away as they moved, coaxing out the gentleness they always wished they had afforded themselves for years.

Summary
They were alike in so many ways. They were both committed to living their truth, even if the realization of what that meant came a little later than either of them wanted. Maybe both of them could benefit from having a bit more of a filter sometimes; it would keep them out of trouble. Both knew how to help others before helping themselves, offering too much of themselves and putting up a strong front so no one would know that they also needed someone to cling to.
Kyo needed someone like Yuchi: shameless in his squishier, more emotional parts, the type to burst into tears as he watched a sad movie, the kind to tell his friends they were his soul mates and cry over the love he spread so easily but never thinly among them. He needed someone sweet, someone sincere and honest, someone who let the emotions Kyo was feeling deep inside himself out into the world so Kyo could follow with his own.
Or: Kyo and Yuchi take Punchuma for walkies! Also, they talk in depth about repression, dysphoria, shame, love, and past relationships.

Summary
Desire, not muddied by depression, felt overwhelming and terrifying. New desires— or rather, old desires that had gone stymied for years— came to the surface in teeth-gnashing ferocity. It wasn't the same at all. It was a need not just to fuck, but to be loved and given the compassion he had been denying himself, and even more terrifying, to be fucked.
He thought it was just a phase he had shaken off, left in the self indulgence of his idiotic and impulsive youth. The asexual misery he had felt since then was what he had resigned himself to being.
Or: Kyo and Die explore long held feelings they've had for each other only to discover that sometimes loving someone is harder than letting them go.

Summary
Die protested uselessly by moaning Taro’s name. “I don't think I can even get hard…”
“We'll see.” His finger twisted Die’s nipple, and he smiled at how Die’s cock twitched in his panties. Taro hoisted Die up to lay his back against him. “Did they cum inside of you?”
Die pushed aside the panties, holding the base of a large plug he had inside of him. “Yes…”
Taro’s eyes flashed with excitement. “Both of them?”
Die nodded slowly. He had started to wear a plug after his threesomes for Taro, knowing how much he liked to see the aftermath of him being fucked. After Die had cleaned up and was saying goodbye to Kyo and Yuchi at the door, he admittedly became excited as he thought of it: how they had no idea he had plugged himself, how they would never know of the games he and Taro would play once he got home.
Or: Die comes home to let his husband have fun with him after his threesome with Kyo and Yuchi.
Set immediately post-"Sanpii", the previous work in the series. Best read as a continuation of that.

Summary
３Ｐ
さんピー
sanpii
noun
threesome (sexual activity)“Oh?” Kyo’s hands gripped tighter, and he ran his fingers up Die’s arm until it rested on his shoulder. “It’s been a long time since I touched you, huh? You missed it?” Kyo ran his lips over Die’s mouth, barely touching him as Die’s lips parted to take him. Kyo instead moved higher up, biting Die’s ear and blowing cold air to tickle him as he asked, “Kiss Yuchi for me?”
Die turned his head to feel Kyo’s lips brush against his cheek, sighing softly. His eyes drifted from Kyo to Yuchi, and he shuddered as Kyo’s hands slipped away. Hesitantly, Die turned to fold his hand over Yuchi’s face, his large palm covering the rouged cheek. He handled Yuchi with concern, running his long, thick fingers through Yuchi’s hair as he tried to come down from the feeling of Kyo’s lips on his, even if it lasted only a moment. He longed to feel Kyo’s touch again, to feel just a spark of what they used to have and see how it changed, that it felt like torture to be touching Yuchi instead.

Summary
“Have you thought of what it would feel like? Die’s mouth, those lips, running down you like this?” Kyo traced Yuchi’s cock from tip to base, licking lower, flicking over his balls, down his taint, lapping over the skin, spreading his tongue over his rim, sucking deeper, deeper, deeper.
Yuchi quivered and moaned, whispering, “Yes… I’ve thought about it…”
“And? Would he be good for you?”
Yuchi’s eyes squeezed tightly shut and he gasped, “Not like you… Not as good as you, but… different…”
Or: Yuchi wants to know if Kyo has ever fantasized about his bandmates before, and gets an interesting answer.

Summary
Kyo didn’t want mercy: he wanted it to be agony. There were only so many ways to feel pleasure but oh so many ways to feel pain, and pain brought so many wonderful sensations. The burning of a wide paddle made his cock throb slowly, and the sharp licks of a flogger radiated to his clenching hole as he bore down with set teeth. The slap of a palm against his skin was as intimate as a kiss, and the piercing pain from the violet wand so impersonal and distracting that he sometimes would be halfway through his orgasm before he even knew it. Kyo dug his nails into his palms as he thought of it, throwing his face down to the floor as he started to beg.
Or: Yuchi feels brave enough to actually rough Kyo up this time.

Summary
“You look gorgeous…” Kyo kissed Yuchi’s lips, licking them slightly, “So sexy…” He dipped to kiss the length of his neck, sucking where Yuchi arched backwards. “Always.” He lowered his voice to a whisper, “I want to fuck you…”
“I thought we’d be doing this tonight, at my place—” Yuchi gasped softly as Kyo bit his ear, “—not now… Fuck…” Kyo manipulated Yuchi’s chest through his shirt, feeling the soft lace of his hidden bra. “Kyo, someone will hear us…”
“I don’t fucking care,” Kyo licked his mouth, parting Yuchi’s lips to suck on his tongue. “Let them see. Let them hear. I don’t care. I want you.”Or: Yuchi gets backstage access to a Petit Brabancon show and utilizes his VIP privileges to the fullest.

Summary
“God, Miya, they’re trying to get laid, not providing you your own little private lessons on how to fuck.” At this, Kyo’s eyes flashed and his mouth twitched a little. Kyo grabbed the back of his neck, eyes searching the room as his face got ruddy and contorted with nervousness. “I, um…” He started to rub the nape of his neck, eyes meeting Miya’s for a second before fluttering away again, [...] “I’ve been in your position, and I know how desperate you can feel. It can make you do some stupid things,” Kyo rubbed his head and growled in frustration as he fought against his next words, “and I don’t want you to do anything you can’t come back from. Just… let me help you.”
“Like… finding me a good guy?”
“If I knew how to do that, I wouldn’t be single. I mean…” Kyo threw his head forward and groaned, “Don’t you get what I’m saying?” He lifted his face to see Miya, still puzzled, and he continued, “No? God dammit.” Kyo paused momentarily. “Let me be your first. That’s what I’m saying.”Or: Miya is sent down a rabbithole of enemas, buttplugs, hookup apps, prepping, and finding his prostate when he accepts Kyo's proposal to be his first.

Summary
“Kyo…” Yuchi bent over to tease his lips over Kyo’s mouth. By now, Kyo had learned the rules of their game, and he allowed to Yuchi manipulate his mouth open to suck over Kyo’s tongue. He remained still, not struggling in his restraints and trying not to moan as Yuchi’s tongue prodded into his throat, wrapping around his own tongue and licking him. Kyo felt a smile grow on Yuchi’s face as he broke their kiss. He removed a glove from his hand and slowly caressed over Kyo’s cheek. Without meaning to, a needy whimper fell from Kyo’s lips, and he apologized immediately.
“You’re such a good girl, Kyo.” Yuchi pet the side of his face as Kyo hesitantly leaned into his touch, rubbing his cheek against Yuchi’s palm. “I thought I’d give you something for being so good.”
Or: Kyo lets the BDSM-inexperienced Yuchi do whatever he wants to him for the night without knowing what he is capable of. In the end, he may regret underestimating him.
Or: Yuchi, the world's most kawaii-est domme.
Sequel to like a girl.

Summary
“My sweet little femboy…” Kyo pressed himself into Yuchi’s back, letting the dress fall and hitching his hands into his ass to spread him. His nose flattened against Yuchi’s shoulder blades as he looked down at the grip he held on him, and he huffed into his skin as his desire grew animalistic. He pushed harder into Yuchi with his hips, mindlessly grinding himself into him, “Or did you want to try being a girl tonight, like me?”
“Only if I get to be fucked like a girl.”
Or: Yuchi finally gets to live out what he's been wanting for years from Kyo.
Sequel to Pampered.
