Work Text:
Kenny was all but eating his mate alive from across the room. They were at a college party, Kenny wasn’t partaking in any of the drinking or smoking, but it didn’t mean he couldn’t be there. Cartman was across the room, a little tipsy and talking with some of their friends. Kenny left when they all started smoking; he didn’t mind, but he knew inhaling that much smoke wasn’t doing their baby any favours.
His hand rubbed just below his bellybutton. He was in loose sweatpants and a shirt that didn’t cover his belly. It was one of his pre-pregnancy shirts that only covered until his bellybutton now that he was 5 months along. His skin was as tight and taught as it could be before his muscles gave way and let his belly form more of a teardrop shape instead of a melon-like protrusion.
But god he was horny. Ever since he’d entered the second trimester he couldn’t keep it in his pants. More so than usual. He jumped Cartman three times a day minimum. He woke up hard and dripping slick, he had to be sated when he came back from class and the only way he could fall asleep was if Cartman fucked his cunt until he screamed.
“And then I swear to god- Jesus. You aren’t even paying attention are you?” Stan complained. He was complaining about something someone had said in his class. Apparently it was wrong, and politically incorrect in some way, but the person was so insistent they were correct oh god it was so boring!
It was all too hard for Kenny to pay attention to Stan’s story when his boyfriend was teasing him from across the room looking like that,
“Hm? No, sorry, what?” Kenny hummed. He couldn’t exactly say what he was thinking, he may have been pregnant, but he was a few months away from having snide comments be excused due to hormones,
“Jesus you have pregnancy brain…” Stan muttered, “You and Cartman get into a fight or something? You’ve been staring at him for like twenty minutes.”
Kenny bit his lip, shaking his head, “No no- we’re still fuckin’ peaches and creme…” He grinned, god he wanted to be eaten out,
“Then?” Stan asked, “I’m bothered by this man, if you’re too distracted about something else spill,”
He shook his head, putting his hands behind his hips, shit his back hurt, “Jesus- sorry man it’s just hormones. Can’t pay attention to anything,” He sighed, Stan gave him a sympathetic nod,
“Don’t worry about it,” He said. As an Alpha, Stan was understandably uncomfortable around Kenny. He was a bonded pregnant Omega, so even talking to him could be seen as trying to sniff him out, “Do you need me to uh, leave? Or do you need to like go be with Cartman or something?”
Again, Kenny shook his head, “No, no, I’m not an animal Stan- I’m just, fuck, scatterbrained,” He was horny. Stan nodded, again looking uncomfortable with the situation. He took a sip of his drink. Kenny didn’t realize it but he was oozing pheromones. All Stan could smell was thick arousal and it made talking to him harder than necessary,
“Alright then- I think I see, Kyle, I’m gonna go say hi,”
“Yeah, of course man,” Kenny muttered, Stan walking away. He took a place leaning against the wall. It took a bit of the load off his feet. Shit he needed to get laid. And now. He couldn’t talk to anyone he was so horny. All he was thinking about was being plowed from behind in Tolkien’s apartment. He was the only one of them who could afford to live off-campus so he had the parties. He wanted to feel his boyfriend plow into him, to have his head rock against the wall. Cartman joined a gym halfway through high school and was now somewhat of a chubby strongman. While he was still notably fat before anything else, under a layer or two was pure muscle. He threw Kenny around like he was nothing. Kenny swore their size difference alone was half the reason they were together. Cartman really knew how to treat him, his dainty little princess.
Kenny was rubbing his thighs together, he found a seat and was sitting in a corner near the bathroom. He could feel how slick he was, and Cartman was only getting hotter. The whole floor reeked of weed, he hoped he hadn’t inhaled anything, but fuck he felt like he was going out of his mind. And then the party got louder and his boyfriend was hotter and then he was walking over to Kenny and talking to him,
“Hey babe, you good over here?” Cartman grinned knowingly, he wasn’t blind to his mate’s pheromones or the bulge in his pants, “My princess doing okay?”
Kenny huffed playfully, “You know,” He intertwined his fingers with Cartman’s, “I’m in one of my moods again,”
Go on, entice him.
“I could use your help? It’ll only take a few minutes, I promise?” He looked up at Cartman with lustful eyes, he knew it was working, Cartman’s crotch was in his face, he was hard as a rock,
Cartman grabbed Kenny by the forearm and quickly hoisted him up. Again, helping him to his feet like he was nothing. Any baby weight he gained Cartman was oblivious to, and when he commented on Kenny’s pudgy belly he praised the swell and called Kenny his special princess,
“Anything for my good girl,”
Kenny squealed and shuffled into Tolkien’s bathroom. Cartman’s hand on his side as he did. They quickly fell in and Cartman was against the door, locking it. Kenny pushed him back, rough, even if it just gently swayed the man to lean against the door. Kenny pushed up against him, grabbing his face and kissing him. He grabbed his hand, making Cartman grab his bulge. He moaned, Cartman squeezing his cock. Kenny pulled off, dropping his sweatpants and taking a little jump, hopping onto the sink. His slick squirted onto the marble and Cartman’s hands were on his thighs. He shimmied his jeans down and pumped his cock with Kenny’s slick,
“You’re so wet honey, so hard for me already, my cock got you acting like this?”
Kenny ground his hips on the sink, “Yeah,” He groaned, his belly inflated and crashed with his breathing, “Its your damn baby- always having me so horny, your fat cock did this to me,”
“Oh yeah?” Cartman rubbed his dick against Kenny’s, the friction making him moan,
“Fuck me, baby c’mon,” Kenny moaned, whining loudly when Cartman pushed in. He fucked in and out of his boyfriend. His cunt was sopping wet and he was so easy to fuck. He was in a state of constant arousal and now he was dripping.
Cartman kept fucking him. Holding him by his waist, cupping the side of his belly and hopping him up on his dick. He felt Kenny’s belly against his own stomach, fuck he loved how tight it was, and the pudge around Kenny’s thighs and ass, even the swell of his tits was amazing. He was so fucking thankful he knocked Kenny up, his mom bod would fit him so well.
“You look hot,” Cartman groaned out, “So fucking messy for me,” Kenny was gasping and choking in breath, he was whining non-stop and his eyes were watering,
“Only for you, fuck deeper!” Kenny ground down as much as he could, rubbing his g-spot, he was going to cum at this rate. His sex drive was so high and he was so sensitive, “My mark! Bite it!” He moaned out and cried when Cartman bit him, making him cum and wrap his arms around his neck,
The good thing about Cartman when it came to sex is that his game was long. He loved edging himself and always made Kenny cum first. He was excellent at fucking Kenny. He could fuck hard while making him aroused and not just shocking his nerves.
He slowed down, drawing in and out with purpose. Tears dripped down Kenny’s face and his nose was all red,
“Fuck, babe, you look so hot right now,” Cartman grunted out. One of Kenny’s arms held him up and the other rested over the bulge of his belly. Each time Cartman thrust he knocked Kenny’s weight back and it made his new body jiggle. Cartman grabbed one of his tits, squeezing it and massaging it firmly, Kenny groaned. His chest caving in as Cartman groped him. He switched to the other one, only making Kenny groan more. His breath quivering and his eyes squeezing shut.
His tits were engorged now. While small they were full and looked so swollen. He didn’t have breasts, but it more looked like his pecs were fully rounded and had a small weight to them. Kenny groaned again when Cartman pinched his nipple. It was warm-
“Holy shit,” Cartman muttered, Kenny opened his eyes, his tits had started leaking milk,
“Fuck!” He cursed and quickly pushed himself off Cartman’s cock, he pushed himself back as quickly as he could against the wall on the sink, his hands were in front of his chest, covering the milk that was leaking out of him and soaking through his shirt, “No-no!”
Cartman quickly overpowered him and lifted his shirt off, stopping it from getting any more soaked. Kenny’s hands were right over his chest again, covering his tits and breathing heavily. He was crying.
“Shit babe, you overstimulated?”
Kenny shook his head, “They’ve never done that before,” His eyes were wide,
“What- oh your tits?”
Kenny took his hands off them. Leaning back and pushing his chest up a little. They were still leaking a creamy white milk,
“Holy shit,”
“Yeah,”
Kenny raised one of his hands and cupped his chest, brushing his thumb over his nipple and then squeezing his breast, the pressure in it released and more milk dripped down his belly. He was lactating. He blushed. Noticing the heat still in between his legs.
“Hey man, babe,” Kenny said quickly, “Was that like, a total turn off or not?”
Cartman grabbed him by the jaw and kissed him, “Total turn on,”
Cartman thrust back into his cunt, Kenny squeezing his tit and relieving the pressure of his chest. He moaned as Cartman fucked him ruthlessly. It was hot. Fuck. Cartman grabbed his other tit, milking him while he fucked him. Kenny ground on his cock. Feeling himself come to another orgasm. He his chest was heaving and he was so close to the edge.
He looked up to the ceiling and shut his eyes. Biting his lip as he moaned and helped Cartman fuck him. He thrust his chest up forwards and Cartman ducked down, taking one of his nipples in his mouth and sucking. Kenny moaned and cried out through his orgasm. Humping Cartman desperately as his entire body pulsed and he came rubbing cum between their stomachs. He felt Cartman cum inside him again, filling him with more of his sperm. He couldn’t get Kenny pregnant again but Cartman would try.
They both came down and Kenny slumped against the wall. Cartman grabbed a towel off Tolkien’s wall and thew it at Kenny for him to clean himself up,
“What if this is the towel Tolkien uses?” Kenny smirked, cleaning the cum and milk off him, he threw the towel to Cartman,
“So what? He gets our sweet love fluids,”
“Disgusting man, you gotta stop calling them that,”
“Love fluids,” Cartman teased,
“Shut up, gimme your sweater,”
Kenny put on Cartman’s sweater. Even if he was male, he thought it would be a little unexpected if he went back to the party shirtless and pregnant with his swollen tits out.
“I looove our love fluids,” Cartman teased, slapping Kenny’s ass as he walked out of the bathroom, leaving his shirt in Tolkiens trash can.
