Sweaty and tired, Suguru dragged himself back to Jujutsu Tech. He was sent on a mission to collect and consume a grade 1 curse and the taste weighed on his tongue and sat in his throat, clawing at his esophagus to ensure he always felt like he was choking. He was more than happy to be done with it and he was a weekend devoid of missions. Yaga finally let him have a breath of fresh air, and he planned to do absolutely nothing.
But a nagging feeling found its way under his skin the moment he walked into the dorms.
Where was Satoru?
Not to call him clingy, but the man was usually pacing by the window waiting for him to come back. He would ask Suguru how his mission was, poke fun at him if he was injured, and tell him the newest stupid thing he’d discovered that day. But silence rang through the dorms. Well, not entirely. Haibara was on the couch, watching TV at a low volume, lying under a blanket, if the TV wasn’t on, Suguru wouldn’t have seen him.
“Hey, Haibara, did something happen around here?”
Uncharacteristically quiet, Haibara responded, “Oh, hey, Geto.” He took a second, clearing his throat, “You could say that?”
He furrowed his eyebrows, he was too tired for games, “What are you talking about, Haibara? Where’s Satoru?”
“He has… uh… ‘baby fever’.”
Suguru scoffed, he found that hard to believe. Satoru, with all he stood for, had ‘baby fever’? No, that couldn’t be it. Satoru never once desired to carry children nor did he want to have them.
Thankfully, Nanami walked into the room, and Suguru spoke again, “Hey, Nanami, where’s Satoru?”
Suguru got a few paces closer and Nanami smelt… different. Sweet like fruit and somewhat tangy, like a cocktail, a delicious syrup with the bitter tang of alcohol. His nostrils flared.
Satoru.
“He went into heat while you were gone,”
Heat?
“We had to manhandle him into his room,”
Manhandle him?
“He’s been crying for you.”
Crying?
Suguru was off without another word to either man. He dropped everything knowing what state Satoru was in. He could smell his scent getting stronger the further down the hallway he went. Satoru’s thick, sweet, tangy smell seeped into the curtains and the floorboards and let everyone know how his day was going.
His Omega didn’t handle heat well. They were too long and too uncomfortable, and an abrupt change from what Satoru was used to. They might be an uncharacteristic couple, but heat and rut aside, Satoru was on top. Suguru liked the way his Omega handled him; his touch was rough and unforgiving, and even though he didn’t have the same pressure points and nerve endings as Satoru, Suguru loved it when Satoru tried to scruff him, grabbing him by the neck, or when he came inside him and shoved a knotting dildo in his ass.
Satoru was a dominant Omega and a heat that reduced him into a begging, snivelling mess made him feel terrible.
Suguru knocked on Satoru’s door and heard a long whine, “Shokoooo, leave me alone, I have enough water.”
“It’s me, Satoru.” He spoke softly and Satoru fell silent.
Suguru pushed the door open, closing it gently behind him. The room was dark and damp. The cloying smell of heat was deep in every fabric. The fan was on full blast pointing at the bed and that’s where Satoru lay, panting heavily, flushed with slick practically pooling around him. His cock was red and angry, had he even managed to cum once?
He walked closer to bed, “Satoru, how long have you been like this?” He brushed the sticky hair out of his face, looking into his glossy, watering eyes,
“Hours.” He panted, “It’s too much, Suguru- it’s too hot, it’s not enough, I’m frustrated and it hurts.”
Suguru sighed, “I know, I know. What can I do?”
Satoru pawed at his uniform, whining higher. Suguru stripped down until he was naked. His own cock was still mostly soft, but the smell of his Omega’s pheromones got him half-hard. Satoru had been fucking him consistently every night of the week, he was likely in pre-heat and neither of them noticed. Suguru was still stretched from last night so they didn’t have to waste any time satisfying Satoru’s heat.
Suguru shimmied into the nest and laid on his back, his legs spread and his hole suddenly wet when Satoru opened him with his slick. Suguru whimpered, Satoru’s cock teasing his ass, really, their roles should be switched. He would never understand why the world made Satoru an Omega and him an Alpha when these were their preferred sexual dynamics.
Even if Satoru’s cock wasn’t as big as an Alpha’s, Suguru groaned at the intrusion. He wasn’t built to take it like this, his insides rang alarm bells in his brain that made his Alpha thrash to not be violated, but once Satoru was fully inside him he loved it.
Satoru fucked him sloppily and he moaned obscenely. Dragging in and out of his hole against the resistance. Even if he lubed Suguru’s hole he was still dry inside. He felt slick drip down his thighs. God, why couldn’t it be coming out of Suguru? It would be so hot. But Suguru wasn’t an Omega, his thick, Alpha cock weighed hard against his stomach, red and desperate for release. Satoru wrapped a hand around it and his Alpha whimpered, gasping and back arching as Satoru fucked him.
“Don’t stop- Satoru-“ Suguru panted,
Fuck, he didn’t want to. He wanted to keep fucking him forever, he wanted to fuck him full until he came but his heat wanted otherwise. Satoru fucked him relentlessly, fast, hard, and slow and steady, but nothing. He got absolutely no relief. No matter how deep he fucked Suguru he couldn’t cum. His hole ached to be filled and he kept oozing shameful amounts of slick. He jerked Suguru off while fucking him until the Alpha came, his knot swelling slightly and Satoru tightened his fist around it, simulating what it would feel like to be clenched down on by Satoru’s pussy.
As Suguru rode the afterglow of his orgasm he felt a pang in his chest watching as Satoru kept trying to fuck him. It felt amazing, but he could tell it was wearing on his mate. Satoru was sniffling and gasping for air. Suguru propped himself up on an elbow and gently held Satoru by the jaw.
“C’mon, talk to me, Satoru.” He needed to be uncharacteristically nice to Satoru during his heats, he was so emotional he couldn’t handle anything less.
“It’s not working, Suguru!” He whined, trying to fuck the Alpha harder.
“You’re hurting yourself,” He scolded, “Come on, come on, slow down,”
Satoru’s hips staggered still as he panted for air. Suguru spoke again.
“Tell me what you need,”
Pitifully, he croaked out an answer, “Switch?” Suguru nodded and Satoru pulled out, his cock hanging hard between his legs, “Please?”
“Of course, c’mon, lay down,” Suguru instructed and Satoru listened. They switched positions and he lay where his Alpha was, trembling on his back with his legs nervously spread. Like usual when they were like this, Satoru showed an absurd insecurity, his hands timidly covering his genitals the best he could.
Suguru knew better than to comment on it. His cock was smaller than he wanted it to be. Satoru’s measly few inches were far from what an Alpha’s cock looked like. Suguru’s dwarfed his in every measurement, and it was a huge point of shame. However, what was more shameful was what was below his cock. Instead of testicles, Satoru had a pretty, pink pussy that Suguru absolutely loved. He’d only been able to eat him out a few times, and while penetration wasn’t his preferred method of sex, he couldn’t say he didn’t love Satoru’s cunt.
But suddenly he hiccuped and Suguru’s face twisted with worry, “Suguru, please, it hurts.”
He plunged into Satoru’s warm heat, moaning at the hot slick pussy that engulfed his cock. He shut his eyes hard as Satoru clenched around him instinctually. He felt Satoru’s weak hand on his bicep, squeezing gently and wordlessly asking for more.
Suguru obliged, fucking him long and hard. Satoru whimpered and moaned the entire time. Sterile cum dribbled out of his cock and onto his tummy. Fuck, Satoru was hot. Sweating and whimpering, begging to be filled. While their sex life was typically reversed that didn’t mean Suguru didn’t have the same urges any Alpha did. He couldn’t help but imagine filling Satoru with cum until he was bloated, his tummy sticking out just the slightest bit from it all. He knew it wasn’t something the Omega wanted, but he could fantasize, couldn’t he?
Satoru nearly screamed and clenched hard around him, milking him from his first orgasm. Satoru’s breath spasmed and he came on his stomach, instinct taking over as he babbled for Suguru’s cock,
“Knot me, Suguru, Suguru, please-“ He gasped, “It hurts so much, everywhere, I can’t take it anymore please keep going-”
Suguru grinned and nodded, fucking in him harder as his knot began to swell again, “Good boy,” Suguru growled out between his teeth and Satoru moaned lewdly,
“Yeah?”
“Yeah-“ He panted, “You’re so good for me, Satoru, so perfect, you’re my good boy,”
The words were fuel to his fire. Satoru grabbed Suguru’s shoulders, clawing his nails into the skin and dragging down so the Alpha moaned obscenely.
“Fuck- I- I love you,” Satoru moaned,
“I love you so much,”
“So much,”
But it hurt too much. Satoru whimpered and squirmed with his Alpha’s dick in his pussy. It wasn’t enough. He wanted to be full, stuffed and almost exploding from how much cum was in him. It wasn’t even a want, it was a need. It was a deep, primal part of him that screamed to be bred and stuffed forever. He could tell Suguru was about to cum from how his hips staggered as he fucked him. Suguru got a specific look to him just before he was going to cum. It was beautiful, truly. His hands were tight, digging into Satoru’s hips and his eyes were screwed shut as he looked up, praying to some unknown god.
Suguru whispered praises and compliments to his Omega as he lost himself, and just as he was about to cum, his head dropped down and his hair covered his face so Satoru couldn’t see him anymore and that’s when he knew to-
“Inside, inside, please, Suguru,” He began to cry, big, fat tears running down his face. He needed this. He needed the stretch, the heat, the warmth of being filled with Suguru’s seed.
“You sure?” Suguru panted, lost in pleasure,
“I need it,” Satoru panted out, “Please, please, I’ll fucking kill you if you pull out,”
Suguru heard the tearful cadence of his words and it only made him hornier. Satoru’s face with pretty, wet tears, all red and sniffing. He was so fucking hot. His hips staggered again and he came inside the Omega, moaning and filling him up. Satoru came again, milking Suguru’s cock and sucking all of it inside him.
He sobbed loudly and unapologetically.
Fuck.
Suguru’s knot filled his pussy and he nearly screamed. How something so lewd could make him feel so whole he didn’t know, but it was incredible. He so rarely longed to be knotted. It wasn’t something they pursued in their usual sex life, usually, he was only knotted in heat so when it happened he went crazy.
“Thank you- fuck- yes-“
Suguru slumped down on top of him as Satoru babbled, completely dwarfing him despite their similar heights. After a few minutes, Satoru caught his breath, panting while Suguru wiped his tears away. Suguru looked at the Omega, flushed and eyes still glossy.
They were going to be like this for days.
