Chapter Text
For all 21 years of his life, Lu Guang thought he was a beta. When his peers presented between the ages of 14 and 16, he remained the same. He didn’t develop a smell and was unable to smell others; he never had a rut or a heat. He was most definitely a beta who did not possess any of the secondary gender characteristics, but…why was he having symptoms so similar to heat at the ripe age of 21?
It started a week ago. While he and Cheng Xiaoshi were cuddling on the bottom bunk, the older boy suddenly put his nose into his neck, inhaling deeply.
“What’s wrong? Do I smell something?” Lu Guang asked.
Cheng Xiaoshi spoke from where he was buried in Lu Guang’s neck. “I don't know, it’s so faint, but I think you smell different than usual. You smell a little bit sweeter and flowery. It soothes me. Did you change your body wash or something?”
Lu Guang was confused. “No? We always used the same one. If I smell like something, I should be smelling exactly like you.”
Cheng Xiaoshi mischievously smirked at Lu Guang's neck. “No, you don’t smell like me, but I have a way to make it so everyone who smells you knows that you’re mine.” Then he started kissing and licking every inch of pale skin he could reach on Lu Guang’s neck playfully.
Lu Guang took a sharp breath when Xiaoshi bit his collarbone a little bit harshly. “Ah, Xiaoshi. It’s still daytime, what if Qiao Ling Jie comes?”
“Guang Guang, please, I missed you. I need you now. I can’t wait until night, huh? Please, please, it’ll be quick,” he pleaded, pecking Lu Guang’s face with every word he uttered. He was so used to acting like a spoiled puppy, knowing Lu Guang would never deny him anything.
And he was right. Lu Guang was ready to give his life with just a word from Xiaoshi, let alone his mere body. He could take whatever he wanted from him, Lu Guang was ready to offer everything he had on a silver platter to him: his body, his soul, his love.
So he did.
After a long preparation session that felt like hours, his trembling legs wrapped around Xiaoshi’s waist, while the other boy finally bottomed out. Both of them sighed in unison when they finally connected.
While waiting for Lu Guang to get adjusted to his size, Cheng Xiaoshi’s hands roamed around Lu Guang’s bare chest, pinching his naturally inward nipples, making them hard and pink until they became protruding, inviting to be eaten. And Cheng Xiaoshi was a man who took invitations seriously.
He started sucking one of the nipples as if he was hungry. He was licking and circling his tongue around the areola, taking the nub between his teeth, and nibbling it lightly from time to time. His hands were also not idle; one of them played with the other nipple while the other one caressed every inch of Lu Guang’s body from his waist to plump ass.
“Ngh, Xiaoshi, it’s enough, don’t play with them anymore, it feels weird.”
“Ssshh, Lu Guang, don't interrupt me, I’m trying to drink some milk.”
“Idiot, ah, I'm not pregnant and I’m not even an omega.”
“You’re wrong, I’ll get you pregnant one day if I try hard enough,” he said with a stupid grin.
Cheng Xiaoshi had been inside of that tight heat for more than he could count but he could never get enough of the way it wrapped around his dick deliciously, twitching with every ministration he performed on Lu Guang’s body.
He especially loved reaching deep inside the other boy. Watching his stomach swell in the shape of his dick every time he pushed inside. Oh, how he wished he could knock him up with lots of pups, so he could see his stomach swell for a different reason.
One of his hands reached Lu Guang’s stomach where his dick inside created a bulge on his lower belly, pressing it lightly. The man under him whined at the action.
“Xiaoshi, don’t play around, I’m ready, move, please.” Lu Guang moved his hips, trying to get any friction, when he saw Cheng Xiaoshi had no intention of moving.
“Oho?” Cheng Xiaoshi was amused. It was so rare to see Lu Guang being this desperate. “You’re so impatient today, Guang Guang. Look at you trying to fuck yourself with my dick.”
Lu Guang looked at Cheng Xiaoshi, challenge prominent in his eyes. “ If you shut up and fucked me properly, I wouldn’t have to do it myself”
That, immediately got him bigger inside. “God, Lu Guang, you seriously drive me crazy.” Maybe he had some kind of humiliation kink because, with those words, Lu Guang turned him on so much he almost popped a knot right then and there.
Cheng Xiaoshi decided not to tease his boyfriend further so as not to make him more annoyed. He put one of the pale, porcelain-like legs on his shoulder, setting a quick, powerful rhythm and searching for that spot he knew made Lu Guang lose his mind. But even before he had a chance to make his planned attack on his weak spot, the white-haired boy came only a few thrusts after, moaning in ecstasy.
Cheng Xiaoshi watched Lu Guang’s beautiful face having the most blissed-out expression as he came. Lu Guang's nails trailed down from his biceps, leaving faint red marks there.
Cheng Xiaoshi fucked him through his orgasm until he heard Lu Guang whining from overstimulation.
He stopped moving and stayed still after hearing that, scared of overstimulating Lu Guang further. He kissed Lu Guang’s face tenderly, not pulling out of the warm hole but also not moving as he waited for him to come down from his high.
It took everything inside of him not to have his way with Lu Guang though. His instincts told him to fuck Lu Guang until he can't form a sentence, until he forgot his own name; he wanted to claim him, own him but he didn't.
Lu Guang was a beta, his body was not suitable to take something as big as Cheng Xiaoshi’s cock to begin with let alone to be fucked roughly by that after he just came. He’d rather have blue balls than hurt Lu Guang.
But, controlling himself proved harder than he thought, because Lu Guang’s face had the most beautiful fucked out expression ever. That's why, to control himself, he had to close his eyes and repeat the national anthem a few times inside until he calmed down enough.
“Guang Guang, was I really that good? You came so fast.” He teased when he saw Lu Guang come down from his high.
“Shut up, I’m just-” he turned sideways, trying to hide his red face. “-a little bit more sensitive than usual today”. He was always thin-skinned, ejaculating prematurely, and even untouched made him embarrassed.
“I can see that,” Cheng Xiaoshi smirked, fully showing his fangs. “But we didn't even get to the good part, now you have to help gege to get his release right?” He pulled out his dick which was still buried deep inside Lu Guang until only the tip remained inside and thrust in suddenly to get his point across.
Lu Guang screamed at the sudden action “Ahh, fuck, Xiaoshi don’t move so suddenly”
“Sorry, Lu Guang, I can't take it anymore, you’re so enticing for me to resist.”
He took Lu Guang’s legs on his shoulder, folding the smaller man in half. Despite his declaration, he was still gentle in his actions. He pulled out unhurriedly, savoring the way Lu Guang’s walls shaped around him, and slammed back rather hard, knocking the wind out of Lu Guang’s lungs. Making him scream in pleasure.
Indeed, Lu Guang was much more sensitive than usual today. He was a mewling mess under Xioashi, tears of pleasure clung to his impossibly long lashes, and behind those lashes hid a pair of lust-clouded eyes resembling the sky on a stormy day.
Cheng Xiaoshi lowered himself, stretching the boy under him even more, reaching the deepest parts of him at the same time he mouthed his Adam's apple. Lu Guang’s body arched to the touch, head falling back, granting more access to his neck for Cheng Xiaoshi.
The black-haired boy took this opportunity to leave more marks on Lu Guang’s pale skin. He looked at the bite mark he had given Lu Guang just a few minutes ago. It pained him to know this mark wouldn't last, that he wouldn't be able to claim Lu Guang even if he wanted it so badly, that they could never be mates officially.
His inner Alpha screamed at him. It told him to claim his mate and give him a mating mark so he could show the whole world who Lu Guang belonged to. But being unable to do so made him delirious.
He licked the scar sloppily, overlapped the slight dents he left before with his teeth, and bit him with a little bit more force than before, still careful not to hurt Lu Guang so much but enough to taste his lover’s blood on his tongue.
He also angled his hips so he could pound directly into just where Lu Guang’s prostate was.
Lu Guang cried at the act, calling Cheng Xiaoshi’s name in a broken sob. He was ruthlessly being attacked at the bottom now. Cheng Xiaoshi set a frantic pace, reaching deep inside the other boy, instincts slowly taking control of him.
Their room was filled with unholy sounds of slapping skin, sinful moans, and wet sounds that came from where they were connected.
“Lu Guang,” Cheng Xiaoshi grunted between his relentless thrusts. Hungry eyes drinking the man beneath him. “Why are you wetter than usual? If I didn't know you were a beta, I’d think that it was your slick.”
“Xiao- Xiaoshi, ah, don’t speak nonsense. It's because you used so much lube”
“But I used the normal amou-” Lu Guang grabbed and kissed the man whose mouth didn't stop saying stupid things even when he had his dick buried deep in his lover’s hole.
The kiss was both to stop him from talking more shit and to feel his lips on him. Even if he had the said man’s cock inside him, carving his insides to his own shape, it wasn't enough, he had to be more connected to him, he had to feel him everywhere.
So, he kissed him, desperately, as if not to forget how he tasted, as if he needed Xiaoshi as much as he needed air.
Far from the sweet kisses they give each other daily, this one carried a longing so intense that it turned into a messy one; their teeth clashed while they kissed, saliva dripped down from Lu Guang’s chin, dampening the pillow under his head.
He gasped into Xiaoshi’s mouth after a thrust reached somewhere so deep he saw stars behind his eyes; toes curling at where they were suspended, hands pulling at the long black locks caught between his fingers.
“Xiaoshi, ah, I'm going to come, I need to come.”
Cheng Xiaoshi growled deep within his chest. “Lu Guang, just a little bit, I’m almost there too” One of his hands reached for Lu Guang’s ignored dick and blocked the entrance.
Lu Guang was so close to coming that being denied release made him cry out in frustration. “Why? Please, let me Xiaoshi, let me come,” he begged, eyes gleaming with tears. He squirmed under Cheng Xiaoshi, trying to move his hand away from blocking his release.
Pink dusted Lu Guang’s cheeks, nose, and even his neck, contrasting with the paleness of his skin. Half-lidded eyes looked at Xiaoshi with want akin to devotion, his face was wet with tears and saliva, his mouth open to let out the most bewitching sounds as he begged him to get his release. He looked sinful, otherworldly; A beauty that can throw nations into war.
Cheng Xiaoshi’s last thread of sanity was about to be snapped at this sight of Lu Guang. He grabbed the hands of the man who was trying to get the alpha’s hands off of his dick. He intertwined their fingers while pressing the naughty hands above the white-haired man’s head.
He looked at steely gray eyes from above before kissing pinkish lips he was very much addicted to. His tongue searched inside the other's mouth, tasting the sweetness of him while he pumped in and out of him at the same time.
Despite his instincts telling him otherwise, he slowed his movements for a moment, trying to distract Lu Guang from coming.
“Don’t be impatient, baobei, ah, I don’t wanna hurt you but I don't wanna be edged again, so let’s come together okay?” he asked, his breath caressing Lu Guang’s still open lips.
“Okay, be quick, my patience is running out.”
“So assertive,” the alpha grinned. “Your wish is my command, my love.” He left a chaste kiss on Lu Guang’s lips before taking a pillow from the side of their bed and placing it under his hips. The new angle made him reach all of Lu Guang’s weak points.
Cheng Xiaoshi took hold of Lu Guang’s thighs, stretching them as much as they would go. Lu Guang moaned wantonly at every brush of Xiaoshi’s dick against his sensitive spots.
“You’re so shameless, Lu Guang? Weren't you worried about someone hearing you? You’re making such beautiful sounds now I’m worried that someone might hear your sweet moans beside me.”
“Shut up, ah, you talk too much”
“I can't help it Lu Guang, my Lu Guang, I can’t bear the thought of you disappearing from my life, I constantly fear that someone or something is going to take you away from me” he whispered between grunts, mouth close to Lu Guangs ears, his breath caressed Lu Guang’s sensitive neck and ears making goosebumps appear on his white skin.
His movements become more powerful, purposefully aiming to hit the deepest part of Lu Guang. Every thrust was getting harder than before as if he wanted to bury himself in the heat of his lover. If possible, he wanted them to be one, melting into one entity. Maybe that way he could keep Lu Guang by his side forever.
“I- I won't disappear, I promised you, ah Xiaoshi be gentler”
“I know but, you are so beautiful, so smart, I can’t help but worry.” his grip on Lu Guang’s open thighs got tighter, sure to leave fingerprints to witness their affairs after they are done.
Lu Guang saw the delirious desire in Cheng Xiaoshi’s eyes and his heartbeat quickened in response. His body was hot and on the brink of coming untouched for the second time. He reached one of his hands and cupped the Alpha's cheek, eyes locked to the pool of Xiaoshi’s eyes. He used the last of his sanity to reassure him, “You don’t have to worry, Xiaoshi, I love you, I’d never leave you”
Cheng Xiaoshi felt too many emotions at the same time. His Lu Guang, the light of his life, looked like a wreck under him from the long hours of their lovemaking, and declared his love to him with so much sincerity in his eyes.
He wanted to wrap him up in softness, to tuck him away somewhere safe where no harm could reach him but also he wanted to fuck him senseless until they see the sunlight, maybe even after they see the sunlight. He wanted to make him scream his name in pleasure until he lost his voice or someone filed a complaint.
“I also love you, Lu Guang, I love you so much” he stood up on his knees without slipping out of Lu Guang, letting go of one of Lu Guang’s legs off his shoulders, grabbing the other ankle on his shoulder before lightly biting it.
He set on a powerful rhythm again, brushing Lu Guang’s prostate with every thrust. His mind was also a mess from pleasure, he started chanting in tandem with his thrusts, half rambling into the skin of Lu Guang’s calf.
“God, I love every inch of your skin” his lips found the place he bit at Lu Guang’s ankle before and kissed the faint teeth mark there. “You have no idea what you do to me”
“Xiaoshi, ah-” Tears of pleasure trailed down from the corner of his cat-like eyes, he was unable to form sentences anymore.
“I love how you feel around me” He trailed his hand along Lu Guang’s white legs, to the place where they were connected. ”you take me so well, as if you were made for me” He watched as his engorged penis went in to the hilt and draw back while his thumb touched Lu Guang’s reddened rim.
It made the other boy whine in protest but it fell on deaf ears as Xiaoshi was almost in a trance.
“I can’t get enough of you, I want to fuck you on every piece of furniture we have” Cheng Xiaoshi took his hand away from Lu Guang’s bottom to set it on his hip. “I don't ever wanna leave between your legs”
Lu Guang's face flashed red because of Cheng Xiaoshi’s shameful remarks, his dick weeped on his stomach pitifully, he was so close to coming.
Powerful thrusts turned into desperate ones, Cheng Xiaoshi got faster and faster until he also felt on edge. His movements became erratic, chasing after his high desperately.
“Ngh, Xiaoshi I’m so close”
“I’m also close” They both felt the base of Alpha’s knot start swelling. “Oh god, I’m about to knot” Cheng Xiaoshi wanted to pull out before his knot formed inside Lu Guang but the white haired boy wrapped his free leg around Xiaoshi, locking him inside before he slipped out.
“Don’t! Don't pull out, I need you to knot me”
Cheng Xiaoshi knotted inside his lover, spilling inside him with a grunt. Lu Guang also came on his stomach with the sensation of Cheng Xiaoshi’s knot growing inside.
He fell on top of Lu Guang. They were both breathless, sweat trickled down Xiaoshi’s face as they tried to catch their breath.
“Are you okay? Does it hurt? It’s been a long time since knotted inside you, does it feel uncomfortable?” Cheng Xiaoshi’s worried gaze trailed Lu Guang’s face.
“Mhm, it’s not uncomfortable it’s-”
“It’s what?”
“It’s nice,” he said, throwing his shyness away.
Cheng Xiaoshi smiled like an idiot, obviously happy at the praise. He maneuvered Lu Guang on top of him so they could be more comfortable while they waited for his knot to deflate.
The white-haired boy started playing with the curls on the nape of Cheng Xiaoshi. “You know, I meant everything I said before. I’m not saying just for the sake of saying it. I love you, and I’ll never leave you”
Cheng Xiaoshi smiled at him brighter than the sun itself. He cupped Lu Guang’s face and kissed him, different than the kisses they shared during sex, it was charged with emotion, slow and sweet.
“I know, and I’m so happy to have you with me. I won’t let you go anywhere; you’re stuck with me forever. Even if you nag me daily to leave you alone, I won’t. I’ll stick to you like gum.” He wrapped his arm around Lu Guang, rubbing his face against Lu Guang's like he always did. Lu Guang let out a small giggle at the gesture, and Xiaoshi felt that he had truly won in this life.
