Work Text:

It happened because Renjun wasn’t careful the night before.

Every Wednesday morning, Renjun woke up with a vagina. That was how it had always been. His parents never questioned it, so Renjun didn’t either.

They warned him that most people wouldn’t be welcoming of the idea, therefore Renjun learned not to show anyone this bit of himself on Wednesdays.

But like all rules, there came a time for them to be broken. Like all virgins, there came a day for them to be deflowered.

Renjun’s first mistake was allowing Mark to sleep over. He liked squeezing himself in between people when awake but valued his space during sleep. Mark had always been good at persuasion, so it was understandable that he managed to stutter his way into Renjun’s sheets.

His second mistake was not wearing shorts. Usually, he donned a plain shirt and shorts to sleep, but again, Mark convinced him to wear just a top and underwear. 

“For easier access,” he’d joked, even though he’d never touched Renjun down there before.

That was the thing about Mark. It was very apparent that he wanted Renjun. There was attraction there, but he never acted upon it sexually. “I’m not gay,” Renjun heard him say before, but it was clear he was not straight for Renjun either.

His third mistake was not hurrying to cover himself as soon as he woke up. Upon rousing, Renjun felt at his crotch and realized it was V-Day after his palm failed to find his usual morning wood.

Shit, Renjun mentally cursed. He hopped off the bed and surveyed himself in the full body mirror. It was definitely Wednesday. His cock was gone and was replaced with a vagina. He was on his way to the closet to grab some loose shorts when he got interrupted.

“Renjun,” Mark groaned and sat up. How long had he been awake? “What-”

Renjun tried to cover himself, pulling down at the ends of his shirt, but it was no use. Mark had already seen Renjun’s front. The flatness of it. The lack of anything that bulged. There was no way he didn’t know.

Heat rose up Renjun’s cheeks. “This isn’t what it looks like.”

He’d tried to sound assertive, but the embarrassment of being seen had Renjun scatterbrained.

“You-” Mark gulped. “Where is your-” Mark gestured vaguely at Renjun’s crotch. “-thing?”

“It’s complicated,” Renjun said, grabbing a worn shirt from some nights ago to further cover himself. “Can you give- hyung!”

To Renjun’s surprise, Mark had stalked closer and ripped the dirty shirt from Renjun’s grip, leaving him exposed. Looking manic, Mark wrestled Renjun’s clothes up to reveal his midriff and underwear.

“Renjun,” Mark said, eyes locked on Renjun’s lower area. “Junnie…”

“I know already, stop looking at it.” Renjun grasped at Mark’s wrist, but the latter was too strong. He was already feeling Renjun up through his underwear, fingers rubbing against the clothed folds.

“You got a pussy, baby?” Mark squeaked out. He circled Renjun’s vagina through his soaked underwear with a practiced finger. Renjun bit his lips to stop the moan that tried to leave. “Why didn’t you tell me?”

I don’t need to tell you everything, Renjun wanted to say, but it refused to come out when Mark manhandled him into the bed, held him down, and began removing his underwear. “Hyung, wait- the door-”

Too late. Mark’s hand started working him open. A finger breached his pussy while a thumb rubbed at his clit. A bitten moan came out of Renjun’s lips. He didn’t want to sound like the girls from porn videos he’d heard playing from Jeno’s room, but the way Mark fondled him was much too heavenly for any other noise.

Being fingered from the front was both similar and so unlike the back entrance. He felt the same feeling of fullness, being shaped into whatever bore into him. But the clitoris? Renjun was shook. Having a clit played with made the ultimate difference.

Soft brushes and harsh touches made him feel so much. Both made his toes curl, persuaded his crotch to push forward to find more pressure.

Mark was relaxed and unbothered. It was obvious this was not his first time at the rodeo. Just the thought that Mark had done this before, had probably done this plenty of times, made Renjun feel like a common whore.

How many women had Mark been with? How many pussies had he eaten, then fucked, then eaten again?

A rush of total envy overtook Renjun. Envious of the women who got to taste Mark’s cock and his wonderful cum. Envious of the women who Mark fucked to Sunday and back, some of which he’d probably fucked bare and came inside.

It was totally irrational. Renjun felt wrong for even thinking about it, for wanting it for himself, but he couldn’t help it when he’d spent half of his teenage years yearning for the unreachable.

But now that Mark was within grasp, Renjun wasn’t sure how to act.

Mark, however, was taking everything in stride.

“Holy fuck, Junnie,” Mark gasped. He used his elbows to pull Renjun apart until Renjun’s knees were pressed on each side. Until his new sex was put wholly on display.

Mark retracted his fingers from Renjun’s hole then peeled back the hood of his clit before rubbing it round and round. The pressure was too much. Renjun was so sensitive, he was sure he felt the exact roughness of Mark’s fingertips.

“Even your pussy is cute as fuck.”

Staring at Mark stare at his pussy awakened something in him, and Renjun quivered at how intently Mark looked.

“Hyung, please!” Renjun begged, attempting to cover himself with no success. He tried cupping his pussy, but Mark grabbed his wrists and pinned them to the side. It warmed his loins. He knew Mark was strong, but knowing something and experiencing it firsthand felt totally different.

Renjun didn’t know what he was begging for. Hyung, please stop. Hyung, please keep going. Hyung, please eat me out the way I’d daydreamed a million times now.

“Please what, Junnie?” Mark croaked, voice cracking at the edges. It was nice to know he had a similar effect on Mark as Mark had on him.

“Please,” Renjun began, pussy clenching at nothingness after Mark withdrew his fingers. He wanted, no, he needed to be filled again. “Please… Lock the doors before you play with my pussy.”

Mark smirked. “All you needed to do was ask, babygirl.”

He hopped off the bed long enough to do as requested, and then he was on Renjun again. He nosed at Renjun’s pussy, the tip grazing his clit just so, as his fingers rubbed the wet opening.

“You smell wonderful,” Mark said after inhaling Renjun’s scent with closed eyes. “Delicious and natural. Totally ripe.”

Renjun didn’t know how vaginas are supposed to smell like, but he figured Mark must know what he was talking about with the confidence he commented with. Mark took a few more whiffs, tongue flicking out to have a quick taste, an appetizer before devouring a five-course meal.

After Mark was done with testing the flavor, he went straight to Renjun’s vagina with a wet tongue and refused to let him get away.

“M-Mark-hyung-”

Goodness gracious. Renjun had heard accounts of how good it was to be eaten out. Renjun read tales of how mind-blowing cunnilingus could be. He already experienced getting rimmed, but this was different. This was a slice of heaven.

Mark slurped at his clit while his fingers dove in and out of Renjun’s pussy. His tongue was wet and forceful and flicked at the little nub with speed. Eating pussies must be Mark’s specialty because Renjun was reduced to glossy eyes and half-formed thoughts in just a few seconds.

“Hyung,” Renjun panted. “Wait-”

It was insane how being eaten out made him tingle everywhere, on his stomach, the tips of fingers, at the ends of his ears. His hands tried pushing Mark off to relieve some pressure because he felt too much, felt too good, as if he was going to reach an orgasm too quickly. But Mark hadn’t budged, merely grappled him by his ass cheeks to lock himself on Renjun’s cunt and restrain him from nudging Mark back or escaping away.

Realizing he could do nothing but take it, Renjun let himself lay pliant and focused on not cumming prematurely. He wanted to savor this moment, keep this in his memory so that he could use it to get off when nights get cold and lonely.

Renjun watched Mark’s actions, recording it in his head like a video on PornHub.

Mark looked exactly where he belonged, settled between Renjun’s milky thighs, dark hair covering his eyes as he twisted Renjun’s clit in his tongue. His mouth jutted out, lapping at Renjun’s cunt in some sort of rhythm. The sounds Renjun’s pussy made was obscene, wet and sloppy as if thick liquids pooled between the folds of his channel.

“So fucking creamy, baby,” Mark said, his bottom lip glistening with pussy juice as he came up for air. “Wanna eat you out all day.”

Mark continued opening him up with an expert tongue, glancing at Renjun every now and then as if to check for his reaction.

Uneven breaths, twitchy fingers, a clenching pussy. These were the reactions Renjun gave him, between moans and grunts and high-pitched calls of Mark’s name.

“Eat it, hyung,” Renjun requested. He squeezed his thighs and settled a hand on Mark’s head as he fucked himself on Mark’s tongue.

It felt unreal being opened up like this. Slowly, meticulously, like Mark was taking his precious time to savor the flavor of his pussy.

Too soon, Renjun felt an orgasm coming. Soft thrumming circled his tummy. Electricity coated his skin.

“Hyung,” Renjun said, pushing Mark’s head away. It only made Mark increase the speed of his lips and tongue. “Take it slow- I’m gonna cum, if you don’t… It’s too early, it’s-”

Renjun was interrupted by his first high. It rippled through him in waves, locking his limbs and keeping his throat closed as his back arched off the bed.

Through it all, Mark stayed consistent, slurping obediently at Renjun’s cunt. He felt slick spurt out of him, not a lot, but it was just enough to cover half of Mark’s face in pussy juice.

“You gotta taste yourself, babygirl,” Mark said, looking delighted at being squirted at, eyes large and lips red and glossy. His tongue kept flicking out, as if he couldn’t resist not having Renjun’s taste on his tongue.

Mark crawled closer until their faces were only inches apart. He kissed Renjun the way he ate cunt, with sucks and slurps until spit and cum mixed between them. Renjun swallowed it all, the moans, the liquids, Mark’s flavor along his own.

Mark reached down their middle, jerking his cock to full length then feeling around for Renjun’s folds. Once Mark found it, Renjun couldn’t stop himself.

“Please fuck it,” Renjun begged. “Please fuck my pussy until it’s sore and battered. Give me your cum. Want to carry your sperm in my cunt everyday, pump it inside until you knock me up, so I can carry your baby.”

“Fuck, Junnie,” said Mark, breathless. The tip of his cock was just at Renjun’s flaps, threatening to infiltrate at any second should Mark so please. “You really want that? You want me to get you pregnant, babygirl? Carry our child in your flat, little stomach?”

“Yes, please, hyung. Don’t you wanna see my tiny tummy bulging from your cock and cum?” Renjun accentuated this by caressing his stomach in a circle. “Don’t you wanna see me all round with your baby? My tits leaking with mommy milk?”

“More than anything, baby.”

Grunting, Mark pushed in and kept pushing. And kept pushing. And kept pushing. It was like there was no end to his cock. Mark growled like an animal as the head finally found Renjun’s cervix. His cock was too big, Renjun couldn’t breathe. He felt so, so full.

“That’s what I’ve been thinking of since I saw your cute, little pussy. Wanna knock you up so I can have you all to myself. Keep you baby-locked to me and me only.”

Renjun’s cunt clenched at Mark’s words. 

“Holy shit, Renjun,” Mark said, amused. He looked down at where he was inserted to the base. The contrast of Mark’s untrimmed pubes against his hairless pussy made Renjun dizzy. “You should feel how tight you get when I say that. You really do want to be pregnant with my child, don’t you?”

Renjun couldn’t lie anymore. His pussy would just twitch again and signal his dishonesty. “Yes, of course I want that. It’d be my pleasure, it’d be my honor, to carry your children.”

Mark smirked. “Then let's fill you up and put some babies in you.”

Mark grabbed him by the waist and slowly withdrew until only the tip was inside before plowing in. They moaned together.

“Hyung,” Renjun said, breathing heavily as he tried to widen his legs and relieve some of the initial sting. “You’re so big, I think I need a moment.”

“No.” He grinned, fingers clutching Renjun’s hipbones as he began his heavy pounding. “You wanted this. You wanted my cock.”

Mark didn’t relent even when Renjun tried to push at his pelvis. He kept fucking into Renjun, abs going taut as his cock slid in deep and hit the wall of Renjun’s cervix every time. 

“You said you wanted to get pregnant with my child. I’m just giving you what you asked for, princess.”

Renjun shuddered at the nickname. This seemed to spur Mark to go faster.

“See? You love it,” Mark laughed. “You love my cock. You love being speared on it. Bet your cunt gets all tight at the thought of me fucking my cum into you.”

Renjun didn’t deny it because it was true. He enjoyed being full despite the dull pain in the beginning. It always ended in pleasure. It always ended with Renjun mewling and pawing at the shoulder of whoever was fucking their cock into him because if he was being honest he liked it when it hurt a little.

“I love it,” Renjun agreed mindlessly. “Fuck my pussy harder.”

Mark held a satisfied smirk as if he knew Renjun would give in sooner rather than later. He fucked Renjun with loud grunts. Renjun met him at every thrust, moaning when Mark’s pubic bone would hit and stimulate his clit.

“My favorite cumslut.”

Renjun bit his lip, hips still working to match Mark’s rhythm. “You mean that, hyung? I’m your favorite cumslut?”

“Haven’t I made it obvious that you’re my favorite everything?”

Mark attached his lips to Renjun’s neck, licking and sucking at the sensitive skin there. Renjun clutched a hand on Mark’s back and an arm around his nape. He needed to touch Mark everywhere, even if he was sweating profusely, especially since he was sweating profusely, from the harsh fucking.

He wanted Mark’s scent to cling to his skin, seep into his pores and find dwelling there. He wanted everyone to know what they were doing in this room, how they were defiling it, how they’ll keep on defiling it.

That Mark and Renjun are Mark-and-Renjun.

Mark continued his fast fucking. Renjun felt each hit in his throat. The stench of sex lingered in the air like fog.

“It stinks of pussy juice and sweat in here,” Mark commented, every other word punctuated with a thrust. “If anyone comes in, they’d be able to tell what we were doing.”

“Don’t you want that?” Renjun said, gasping every time they rocked together. “Don’t you want everyone to know I’m your personal pocket pussy?”

“I do, babygirl. You really want to be on my cock everyday, huh?”

Renjun didn’t answer. He showed it instead. With a harsh grunt, he flipped them over until Mark was on his back. Renjun began to ride him like a cowboy, hips moving deliriously fast. He wanted Mark to cum soon. He needed him to spill his manmilk inside so they could have a baby together.

“Shit. That feels so good, Renjun.”

Mark grabbed a handful of ass and began jackhammering into Renjun’s pussy. It was rapid. Shallow but felt so deep.

It was too much at once. Renjun’s whole body convulsed as he experienced an orgasm.

“Fuck, Junnie. That’s it! Milk my cock just like that.”

Renjun felt his pussy clenching as he came, his cunt creaming all of Mark’s cock until all of Mark’s pelvic area was wet and shiny with his pussy juice.

Exhausted, he dropped down and let himself be used.

“So fucking messy. You’re gonna clean my cock later.”

Renjun gave a slight nod, brain totally overrun with nothing but sex and cumming and getting pregnant.

“Fuck, babygirl,” Mark blurted through his thrusts. “I’m gonna cum in your cunt soon.”

Mark flipped them over again and continued to pound Renjun’s pussy into the bed.

This position re-energized Renjun. “Shit, yes, that’s it, hyung. Knock me up.”

“Gonna get you pregnant, babygirl.” Mark hissed every time his hips met Renjun’s. “Gonna cum inside you again and again, then plug you up so it catches. Get a baby in that oven.”

“Yes, yeah- fuck yes, hyung, please-”

The wet sound of Mark fucking into Renjun’s creamy cunt echoed on the ceiling. The bed creaked against the wall at each move. His neighbors could tell what was happening for sure.

“Here it comes,” Mark said, face scrunched. Then he shuddered, releasing days-old cum inside Renjun’s hole, pushing himself deep so that his sperm could swim past Renjun’s cervix. “Fuck, babygirl. Do you feel that? Do you feel my cock knocking you up?”

Impossibly, Renjun could. If he focused enough, he could feel Mark’s cock pumping cum in huge spurts, the frothy sperm sloshing into his womb, accumulating there as if waiting to clutch on to one of Renjun’s unsuspecting eggs. Renjun tried to close his legs, tighten his hole so that none of Mark’s cum leaked out of him.

“I feel it, hyung. It’s inside. It’s gonna knock me up, I know it. If it doesn’t, you have to cum in my pussy again, hyung, please.”

“That’s the plan, baby.”

Mark stayed inside, doing shallow thrusts into Renjun’s cunt throughout the whole mess, and even when he softened, Renjun’s pussy shrunk with it, as if not wanting to spill any of Mark’s cum.

They spent the whole day locked in Renjun’s room, only getting off the bed to eat, drink water, or go to the bathroom. Renjun didn’t shower, and neither did Mark. They used up all their available time chastising every corner of Renjun’s room.

After explaining that Renjun only had his pussy on Wednesdays, Mark had the idea of using him all evening. It seemed if his pussy was in use, it wouldn’t turn back into his usual cocklet.

Renjun warmed his cock through the night, pussy clenching at each tiny movement in their sleep.

Accidentally, he was shaken awake in the middle of the evening to Mark whispering filthy things into his ears as he used and abused Renjun’s cunt with some rough sex. Renjun fell asleep to the sound of his creamy pussy squelching at each thrust and Mark’s chants of, “My personal fuckhole. My cute cocksleeve. Renjun, baby, you’re mine.”

It was already morning when Renjun came to again. Mark was snoring lightly, his soft cock had almost dislodged from Renjun’s hole. A mixture of sweat, cum, and pussy juice was smeared all over Renjun’s cunt.

With a moan, Renjun reached behind him to get Mark going again. He was hard in less than a minute, talking quietly in his sleep like he was dreaming of fucking Renjun still.

Renjun popped Mark’s hard cock further into his pussy, and with an elongated groan, he pushed his little cunt back until Mark was lodged all the way inside again, exactly where he was supposed to be. As the head of Mark’s cock was stopped by Renjun’s walls once more, Mark woke up.

“This is the best way to wake up, babygirl. Inside a tight hole,” Mark said, voice rough and grainy from sleep. “I was dreaming that I was fucking you while you were pregnant. You up for that, baby?”

Renjun moaned at the image.

“I’d let you hit it even when I’m in my second trimester.”

“Yeah?”

“Yeah, but no later.”

Renjun’s pussy became forever.

Mark fucked him all day again and again and again until, weeks later, Renjun surprised him with a positive pregnancy test, which they celebrated with more fucking.

No room was spared from their sex. Renjun was pregnant. Mark had him baby-locked. Mark gave Renjun his cum every day and night like it was a part of his daily meal.

Life was good.
