“Megs, do you need a drink? Do you need me to put sunscreen on your back?” Megumi brushes Yuuji off every time. It’s not like he’s annoying him, god, no. But when Nobara invited him over, he didn’t think Yuuji would be practically glued to his side all day. He sometimes goes off on his own to talk with Hakari and whoever else he finds in his path, but he and Kirara are good at the edge of the pool, dipping their feet into the warm water.
The sun is really burning today, even though he made sure to put generous amounts of sunscreen on his body, his arm is still itching. Nobara left them some snacks at the pool and went off to talk with her guests. Surprisingly enough, even Gojo and Geto bothered to show up, an event that occurs once every blue moon just because Gojo likes showing off, dragging Geto along.
Megumi is thankful he’s currently too busy parading his new fancy baby blue bikini to bother Megumi. His straw hat and his sunglasses completely block his view so he can’t see inside Nobara’s house. To his side, Kirara keeps on complaining that her boyfriend spilled his drink over his matching swim trunks and had to change them. What a shame, Megumi thinks.
All is relatively well, until the worst man alive arrives. His relationship with Sukuna is so complicated, that Megumi just refuses to give it a name. Call it an ex-situationship, an ex with benefits, whatever.
As soon as he comes through the door, Sukuna doesn’t even bother to entertain anyone inside. He just moves all the way to the back yard, his eyes darting towards Megumi immediately, as if he could smell him from miles away.
“Did that brat abandon you? What a shame sweetheart, y’know I would never.” Sukuna sees Kirara right next to Megumi, but he doesn’t care enough to acknowledge her presence. Instead, he sits down next to Megumi, his arm wrapping around his waist. “Especially not when you’re almost fucking naked. Is he really that stupid?” Sukuna chuckles deeply in his ear and Megumi hates to admit that makes his pussy leak out a drop of slick.
“Stop it, Sukuna. I told you it’s over. And don’t touch me.” Megumi pushes his arm away, silently hoping Sukuna will just leave before he embarrasses him any further to Kirara, who is definitely uncomfortable with this.
“Uh- I’ll give you guys some space to, y’know, talk..” Kirara announces as she walks away, mouthing a ‘good luck’ to Megumi. He really doesn’t have the energy left to battle with Sukuna again. Especially since Yuuji will probably be back any time soon. In their early relationship days, Yuuji and Sukuna used to have their way with him, threesomes weren’t anything new to Megumi, but fuck, he had to call it off before he’d find himself addicted to Sukuna again.
“C’mon Megs, nobody’s here anymore. Why don’t you just…” Megumi growls when Sukuna’s hand approaches forbidden territory, inching closer to his barely covered cunt. Because of this, Megumi finally gets to take a look at Sukuna, turning his head to scold him but instead he bumps into his muscular chest, his tanned skin and his tattoos portraying a lustful image, it tempts Megumi to forget about everything he stands for, to just do it, reason be damned.
Not only does his body look like sin on legs, but his sunglasses and the silver chain around his neck, paired with the pink swim trunks make him look straight out of a shitty porno. Megumi thinks he might be the co-star in it.
Yuuji is still nowhere to be seen, probably chatting with Nobara.
“Why should I let you fuck me, Sukuna? You know, your brother really filled me up so much yesterday, I’m surprised I’m not still bloated. I don’t know if you’d even fit..” Megumi whispers, humming when he hears Sukuna’s sharp inhale. If he’s going to do this, he might as well go big or go home. Megumi stands up, knowing Sukuna is staring, and he bends over to whisper in his ear one last time. “Come find me tonight, if you can steal me from under Yuuji’s nose, that is.”
Sukuna is never one to back down from a challenge. Especially not when his prize has a soaking wet cunt that’s always ready to use.
————
By nightfall, everyone is barely alive. Some are either falling asleep, some too drunk. But Megumi doesn’t feel like either. Not when someone has a promise to uphold. In fact, he feels electricity coursing through his veins, excitement builds in his gut.
On the couch, Gojo refuses to leave Geto’s lap. He doesn’t move an inch, wrapping his arms around his neck, arching his back in such an obscene manner that Megumi has to look away, finding it inappropriate to stare at his father figure like that. Geto isn’t any more of a saint, his hands squeezing Gojo’s butt. Megumi is thankful that he at least gave Gojo his hoodie a few hours ago just so he won’t be almost naked the entire day. Geto said it’s so he doesn’t get cold, but Megumi knows it’s just a facade and he’s just jealous that other people have been staring at his husband inappropriately.
But Megumi is a hypocrite to judge them, when he’s also been sitting on Yuuji’s lap for an hour now. He doesn’t like when there are so many people around him, it makes him really overwhelmed so he’d rather just stick with Yuuji and his parent figures who keep groping each other right next to them.
That is until he spots something. Or rather, someone. Sukuna is talking with some girl, clearly flirting, and just as Megumi is about to find an excuse and go up to them, Sukuna leads her into the pool. Well fuck you too asshole! Megumi won’t lose to him, that’s for sure. Before he can think this through, he snatches Yuuji’s hand and drags him outside to the pool, confusing Gojo, Geto and even Yuuji, who was still making small talk with them.
Megumi watches as Sukuna gropes her ass under the water, ‘teaching her how to swim’ for sure. He doesn’t hesitate, throwing himself against the wall and kissing Yuuji, hot and hard enough to draw everyone’s eyes on them. Megumi lets out an embarrassingly loud moan when Yuuji slips his tongue inside his mouth, his hands gripping his waist firmly, keeping him pressed against the wall. Megumi wraps a leg around Yuuji’s waist, humping against him.
Sukuna is fuming, Megumi is sure. He opens his eyes to look at some point into the kiss, and sure enough, Sukuna already dipped the girl, disappearing from his sight entirely. Megumi feels his heart racing with pride. Sukuna never stood a chance against him. Thankfully, Megumi is well acquainted with Sukuna’s thought process, and he knows exactly where to find the older man. He pulls back from the kiss, giving Yuuji one last peck on the lips before excusing himself. “Mm, I need to refresh my eyeliner, I’ll be back in a sec!” That’s the last thing Yuuji hears before Megumi disappears too.
Megumi barely manages to close the bathroom door behind him before Sukuna cages him in, gripping his jaw with one hand. “What the fuck was that about Megumi?” He really wants to punch Sukuna for having the audacity to ask this.
“What? You were two minutes away from fucking that girl in Nobara’s pool, don’t give me that attitude.” Megumi rolls his eyes, pushing Sukuna who naturally doesn’t budge an inch, clearly angry. His eyes dart at Megumi’s lips, they were bitten. Of course, Yuuji loves marking him after all.
Sukuna shakes his head in disapproval, no emotion behind his eyes. Megumi should be scared, but Sukuna is nothing but another challenge for him to face, a very thick one at that.
“Fine. If you wanna roll your eyes at me, I’ll make sure you do it properly.” Sukuna sits him down on the sink counter, his hands grabbing the small top piece and ripping it off. Megumi gasps, wanting to scold Sukuna for his carelessness but before he has the chance to do so, Sukuna buries his face in his tits, mouthing at his pink nipples.
His body trembles under Sukuna’s expert, warm tongue. It’s been a few months since he last felt Sukuna this close, no wonder his pussy leaks in his bottom piece, soaking it in his slick. Megumi mewls when Sukuna bites his nipple, massaging his other breast with his free hand.
“You slut, acting as if you don’t want this, don’t want me, but your cunt immediately starts leaking the moment i look at you. Poor Yuuji, having such a slut as his boyfriend.” Megumi bites his already bruised lip at the mention of his boyfriend, but he can’t really deny anything, can he? Not when his boyfriend’s brother is caressing his pussy, pushing his bottom piece to the side, teasing his folds.
Megumi can just barely hear the loud music from outside the door. He can’t be bothered with it though, not when Sukuna taps on his clit like it’s a fucking toy, and just as Megumi grabs his hair to push him away from his chest, Sukuna presses on his clit, hard. “Mngh, why don’t you hurry up? Yuuji will definitely catch up soon!”
Sukuna lets his nipple go with a wet pop, his eyes burning with desire and desperation. “So? Let him. In fact, he can join us if he wishes. Though, I’d rather have you for myself tonight. That selfish bastard already claimed you once.” Sukuna gathers some of his slick on his fingers and forces two inside his throbbing,sticky hole. Megumi throws his head back, his manicured nails scratching his tattooed biceps.
“ ‘Kuna, I need your fucking cock, p-please!” Megumi begs, something that he really doesn’t enjoy doing but Sukuna won’t accept anything else. He loves torturing Megumi. His nails scratch his walls so well his brain turns to mush, eyes watering. The two brothers are almost identical when it comes to sex, they both love to torture Megumi and force out as many orgasms as they can out of him.
Sukuna’s fingers find his sweet spot easily, milking an orgasm out of a trembling Megumi. Sukuna doesn’t say anything about Megumi scratching him, not even when he draws blood. Megumi finds that hot.
His free hand grips his jaw, forcing Megumi to open his mouth. He doesn’t know what he wants at first, until Sukuna spits directly in his mouth, speeding up his fingers. Megumi’s ears are ringing, whimpers keep on pouring out of him. “Swallow it.” Megumi can’t do anything but obey. He closes his mouth, his throat bobbing as he swallows.
“Mm, your hole is so excited baby. Look how it’s winking at me.” Megumi makes the fatal mistake of looking down between his legs, where Sukuna’s fingers are still pistoning in and out of his hole, but more than that, he’s leaking slick all over the counter. His hole squeezes around Sukuna’s fingers, keeping them trapped inside.
Sukuna wants him to cum.
“No blessing, want you to squirt on my fingers, yeah? Go on. You wouldn’t want to disappoint me, no?” Megumi squeezes his eyes shut, tears drying on his cheeks. His hips move on their own, chasing his orgasm while Sukuna curls his fingers inside, completely breaking Megumi with one simple move.
Megumi, like the good boy he is, does exactly as he’s told. His face scrunches up as he squirts, forcing Sukuna’s fingers out. He wets Sukuna’s chest, his abdomen, and even his trunks. He’s embarrassed, but he can’t stop. Once he’s done, he tries to close his legs just for Sukuna to slap his thigh, glaring at him. “W-What? Don’t you see I’m exhausted?” Megumi tries to jump down, but Sukuna catches his wrists, pinning them to the mirror behind.
“You think I’ll just let you leave? I made you squirt like some hungry for dick whore, and now you think you can just leave me like this?” Sukuna looks like he wants to continue, but instead he shuts up. Probably an idea creeping up in his head. “Fine by me then. I’m sure that hot chick would love to fill in for you.” Sukuna backs away, heading for the door. Unfortunately for him, Megumi doesn’t like sharing his things, that includes his stupidly hot ex who keeps fucking the living daylights out of him. No matter how fast he runs, Sukuna will always catch up.
Just as Sukuna is about to reach the doorknob, Megumi throws himself in his arms. Sukuna smirks, watching him pull down his trunks. Megumi blushes at the sight of his naked cock, standing up and proud. He’s clearly been hard the entire day, leaking pre cum and the tip is an angry red. He needs release, and only Megumi can give it to him.
“I’ll make you swallow your words, asshole.” Megumi lifts his leg, despite the awkward position, he manages to position his cock at his entrance. He rubs it over his clit, allowing it to slide between his folds but not putting it in. Sukuna knows he’s trying to punish him, but after all he’s only delaying the inevitable. He could definitely just bend him over the counter and fuck his brains out, but what’s the fun in that? His ego needs to know if Megumi still craves him as much as before. If he’d do anything to keep him here.
A gasp leaves his mouth when the tip pushes inside, just enough to drive him insane. He doesn’t want just the tip, he wants the whole thing in his womb! Maybe Megumi lost his mind, but he has to force it inside all the way. This way, he’ll prove himself to Sukuna. He’ll prove it to himself that he’s the only one who can get Sukuna off.
“How many others did you fuck?” Megumi grits his teeth, his pussy clenching around the head, trying to force more of it inside.
Sukuna isn’t having any of it, his hips rolling and once Megumi pulls away again, Sukuna loses it. He growls, grabbing his waist harshly and bending him over the counter, much to Megumi’s surprise. Like this, Sukuna has complete control over his trembling and sensitive body.
“I fail to see how that’s any of your business, blessing.” Sukuna bites his ear, his hand wrapping around his neck, forcing his head to loll back and his eyes to focus on the mirror, where Sukuna sadistically stares back at him.
Megumi really hopes no one hears them, he prays the music is loud enough to mask what is going on here.
Sukuna’s now fully inside him, his hole stretching to accommodate the intruder. He really hopes Sukuna will come inside him.
“You dirty bitch, you’re getting off on being treated like a toy. I should’ve known that’s what you wanted. Sluts like you are only satisfied by being humiliated.” Sukuna scoffs, slapping the meat of his ass, admiring the way his spine arches, it must be painful.
Sukuna’s cock feels heavy in his loose pussy, but it’s finally back where it belongs. Nobody else deserves this but Megumi. His cunt was moulded specifically to take Sukuna.
His eyes are watering, eyeliner mixed with tears paints his face, making for a sinful image, one straight out of a porno. ‘Twink gets his pussy bred in a party bathroom while his boyfriend is in the next room’ Yeah, Megumi loves it. He doesn’t care if he’s a slut, a whore, anything. Sukuna and Yuuji love that about him, so there’s no need for change.
“Look in the mirror, slut. Don’t make me repeat myself. Look how I’m destroying your pretty cunt. It’s all mine ain’t it?” Megumi shakes his head, but he still obeys, looking in the mirror to see Sukuna’s sadistic grin. “Oh?”
“Y-Yuuji!” Megumi moans, hips rolling to meet his rough thrusts. The sounds of skin clapping on skin is so loud, he’s surprised they weren’t interrupted. He can’t believe no one even tried to come in all this time.
“I don’t see Yuuji anywhere baby, I think he wants me to fill up your pussy for him. Wanna be a sweetheart and do what he asks?” Megumi nods eagerly, his pussy throbbing as Sukuna gets closer to an orgasm. He can feel it, the way it makes him feel so warm inside. It has to be.
“Yes, yes baby- fuck!! Watch me knock you up bitch.” Sukuna bites into his neck, closing his eyes as he empties himself into Megumi’s welcoming womb. His whimpers are so loud he thinks the entire house heard them, but he finds himself unable to care as he squirts for the second time tonight, eyes rolling in the back of his head, tongue lolling out.
Megumi loves how warm it makes him feel, and he especially loves how it leaks out of him when Sukuna pulls out, a groan leaving his throat at the sight. It looks so hot, his cum dripping out of Megumi.
“Hey, let’s get you back on your feet before that brat notices.” Megumi is too out of it to hear him, and if he does he can’t really understand what he’s saying. He nods, eyes closing for a moment. He hears Sukuna swear and the world blacks out around him.
Sukuna now regrets breaking him.
——
Yuuji can’t help but gulp at the noises. He tried to peek inside, but he didn’t want to risk them finding him out. So, noises will have to do. He can hear Megumi’s sweet moans, his begging, the way Sukuna thrusts inside his baby boy. Fuck, he’s so hard. He bites his lip in an attempt to silence himself.
If anyone happens to see him peek through the door, they don’t say anything. What could they? Ever since his mother married Sukuna’s father, she kept begging him to share everything with Sukuna as if they were twin brothers. Candy, toys, homework, everything was for the two of them. Though his mother is dead, he makes sure to keep his promise. Even if that means sharing his boyfriend with his step brother. Yuuji is a good brother.
