Work Text:
Ichimatsu wanted to try something during sex again. He was good at getting worked up and running his mouth, something that always ended up happening whether he wanted it to or not. Normally Karamatsu didn’t respond to any of it, something he was too scared to ask whether or not he actually liked what he was saying. But last time they’d fucked, Ichimatsu said something that had Karamatsu tightening up so hard around his dick it almost hurt.
‘I’m gonna breed up your slutty pussy’ or something to that effect. It sounded so bad outside of sex, Ichimatsu would rather set himself on fire than to repeat the stupid shit he said while he was balls deep in Karamatsu’s pussy. He could deal with the cringe this time, however. Especially when he needed to formulate how to get Karamatsu to do what he did again.
An enthusiastic Karamatsu actually acting like he was enjoying what they doing would be a dream come true. For someone so loud and annoying normally it was always a little unnerving that he was so quiet when Ichimatsu himself could never shut the fuck up. Had he really never said about breeding Karamatsu before now...?
Wait.
Of course.
Karamatsu had talked about wanting a son a few times when they were all together. Ichimatsu never paid much attention to those kinds of conversations. Having a kid was the last thing on his mind, but it clearly wasn’t for Karamatsu. He’d somehow never put two and two together that his brother had a fertile womb to go with his nice, tight pussy. Karamatsu would be the one giving birth to that son, and if Ichimatsu was lucky, he’d be the father.
So many questions ran through his mind. Did Karamatsu just have a breeding kink, or was he having that so-called ‘baby fever’? Was he even on birth control? They used condoms, but there was always that risk. Did that turn him on? Why couldn’t he just ask Karamatsu these things himself?!
He needed to experiment.
He wanted to experiment so badly. But he was still himself; unable to say what he wanted and not brave enough to say it even if he could. It pissed him off, he needed to act, not daydream about it.
Lying slumped over on the table pretending to be asleep was definitely not helping him achieve his goal. Ichimatsu usually watched Karamatsu like this when they were all together, since talking to him casually would be extremely weird and out of the ordinary to the rest of them. Karamatsu was always by himself, admiring himself in the mirror or pretending to read, and Ichimatsu could watch him do either forever.
He couldn’t stop staring at Karamatsu’s slim waist and toned stomach this time. He was wearing his tank top today, showing off his arms and his pretty neck that Ichimatsu wanted to litter with love bites.
That tank top wouldn’t fit anymore when Karamatsu was 8 months pregnant with his child. His lithe body would fill out, his thin waist replaced by thick hips that Ichimatsu could sink his fingers into. He’d have to throw away his current persona and become a dad, all because of Ichimatsu. Karamatsu had to have thought at least that far if he really wanted a child, or at least Ichimatsu hoped. If he was ready to completely change his life then Ichimatsu could plant the seed in his head.
Normally they didn’t do anything in their shared futon, but Ichimatsu was desperate. Every attempt at even speaking to Karamatsu had failed today, and now Karamatsu was slow getting to bed. He was giving Ichimatsu way too much time to overthink everything and freak out over every single detail. To the point that he didn’t notice Karamatsu had walked in the room until he sat down beside him on the futon.
“Good night ‘my brother’! May you have wonderful dreams tonight...!” Karamatsu said, and Ichimatsu socked him with his pillow in response. They smiled at each other for a second before Ichimatsu turned around grumpily and Karamatsu shuffled under the blanket. He just needed to wait a little longer until the rest of his brothers went to sleep...
He finally turned over hours later, and nervously slotted himself against Karamatsu’s back, wrapping his free arm around his waist. He was fast asleep, a stream of drool leaking from his mouth onto the pillow. Ichimatsu wished Karamatsu was facing him so he could lick it directly from his mouth, but it wasn’t the time for that. No, he needed to wake him up gently.
He kissed a line along Karamatsu’s neck, stopping at his ear to nip and suck on it. Karamatsu stirred then, a soft noise of pleasure leaving his lips before he came to his senses. He didn’t say anything, letting Ichimatsu play with his ear. As much as he loved it when he licked a particularly sensitive spot that made Karamatsu tense and wrap his leg around his, it wasn’t what he came here to do.
“You know what I wanna do to you?” Ichimatsu whispered hotly against his ear, and Karamatsu shivered.
“We can’t have sex here. The others...” Karamatsu protested. There was no bite to it.
“Yeah, I wanna breed you properly, get you nice and pregnant with my baby,” Ichimatsu blurted out before he could stop himself. He didn’t mean to say it like that! Or at all!!!
Karamatsu groaned, his body tensing and shaking in Ichimatsu’s grasp. His telltale sign of an impending orgasm. If that’s all it took to get him to cum, then what was stopping Ichimatsu from saying more? Doing more?
“I’m gonna bend you over and fuck you without a condom next time we go to a hotel. I’ll make sure you’re pregnant by the time we leave the next morning,” Ichimatsu said, biting the crest of the Karamatsu’s ear.
“We can’t...” Karamatsu said weakly. His body said otherwise, sweat dripping down his temple as he fought to keep himself from cumming.
“Why not? You clearly want it,” Ichimatsu said, snaking his hand down to caress Karamatsu’s stomach. It fluttered under his touch, Karamatsu groaning as he grasped at Ichimatsu’s hand with his own. “How many do you wanna give me? One? Two?”
“Four,” Karamatsu said, squirming in Ichimatsu’s grasp. He had answered that question suspiciously fast, and God did it turn him on to know that Karamatsu had already thought this whole scenario out beforehand.
“Four?”
“Quadruplets. I need you to fill me up so everyone knows I’m yours,” Karamatsu groaned out, burying his face in his pillow to hide his embarrassment.
Ichimatsu’s brain stalled for a moment. This was the first time Karamatsu had ever reciprocated his terrible dirty talk! Maybe there was a god after all!
“I- I could fuck you right here, knock you up right next to our brothers,” Ichimatsu said, planting kisses along the back of Karamatsu’s neck. “They won’t know how much of a slut you’ve been until you start showing.”
“I’m not... a slut...” Karamatsu said, voice muffled against the pillow. His entire body was shaking, his hand gripping the one Ichimatsu had on his stomach so hard it hurt.
“Yeah you are. I’m not even touching you and you’re this close to cumming from the thought of carrying my baby,” Ichimatsu said, reveling in the way Karamatsu’s body quaked against his. He was so hard it hurt. It would be so easy to pull Karamatsu’s pajama bottoms down and bury himself in that warm, wet pussy of his right now, so easy to spill his seed inside his willing womb in front of all their brothers.
He wouldn’t. He couldn’t even when every fiber of his being was telling him to claim Karamatsu and make him his. It wasn’t a noble decision; Ichimatsu was petrified of the consequences. Being disowned by their family was one thing, but actually ruining Karamatsu’s life was another thing entirely—
“Ichimatsuuu... Don’t stop. I’m so close,” Karamatsu slurred, voice thick with lust. Ichimatsu hadn’t realized he’d frozen completely, lost in his own thoughts for a moment. He didn’t even know what to say! He had to think of something, anything...
“Maybe I’ll keep you pregnant. I’ll pump you so full of cum you’ll never be empty for longer than a month. You’ll be my personal baby factory, won’t you, Kara?” Ichimatsu said, biting Karamatsu hard on his neck.
Karamatsu made a strangled moan in response, body tensing and jerking uncontrollably as he came untouched. He was shuddering and gasping, trying hard to stay quiet. Ichimatsu held him close, in shock at how well this had all worked out. Maybe he was actually good at something after all!
“Ichimatsu,” Karamatsu said a few minutes after his orgasm had faded. Ichimatsu squeezed him affectionately.
“Yeah?”
“Let’s go to a hotel right now. I need you to get me pregnant tonight.”
