Sukuna smirks when he notices your eyes almost bulging out of their sockets as they drop to his defined abs. 

And the moment he pulls his shirt up to reveal his chest, you turn almost pink as you snap your head to the side so you’re not staring. 

Cute. 

“We have guests, Sukuna, jeez!”

You turn to your father berating his brother for his indecency, especially when your younger brother’s friends are running amok at home. Not to mention their parents mingling and chatting outside. 

You take a peek at your uncle to see him glancing at you, his eyes dancing with mischief. 

“I’m your guest too, you know,” he mutters. “And your child was the one that soiled my shirt.”

“Just wear the fucking shirt.” Your father slaps a dress shirt on his chest. 

“Cursing in front of the children,” Sukuna clicks his tongue mockingly. 

At this point, your father has already left the room. You turn to your uncle and see him pulling the shirt off the hanger and unbuttoning it. He glances up at you, his eyes searing hot as they land on you. 

“You’re fine with Uncle Kuna being shirtless, right?” 

You blush, not sure if it’s because he used the childish name you used to give him when you were eight, or because of what he said. Or maybe even because he’s topless and so damn handsome even as he fits his muscular tattooed arm into the sleeve of your father’s shirt. 

Understanding that he’s looking for an answer, you nod your head meekly, still gaping at him as he gets dressed. 

The sharp corner of his lips turn up into a smirk. As he slowly buttons up the top, he makes a show of running his eyes down your body. 

His niece looks good in that yellow summer dress. The colour of it against your skin. The way it fits on your body. Sukuna almost wants to bite his lip and groan, eyes nearly rolling to the back of his head. 

Instead, he settles on nodding at your dress and saying, “Like that colour on you.”

Dropping your gaze, hoping that somehow alleviates the redness of your face, you murmur, “Thanks, Uncle Sukuna.”

“Uncle Kuna,” he corrects teasingly, using the term you used for him when you were a kid. 

He laughs when you let out a quiet whine and stare up at him in shock, like you weren’t expecting it to even manifest audibly. 

The top two buttons of his shirt are undone and you’re almost ogling when he asks, “Do you think your dad’s going to nag again if I walk around like this?” 

You swallow and flick your gaze up to meet his. “I think so.”

He makes a show of rolling his eyes as he fastens one more button. “I can’t breathe in his puny ass shirt,” he complains. 

The shirt does look like it’s suffocating him. But honestly, he looks good in a tight fitting dress shirt that hugs his muscular body. Actually, he might even look more indecent like this than when he was shirtless. 

“Let’s go grab a beer or something,” Sukuna mutters, walking toward you. He places a heavy hand on your shoulder, his palm calloused and warm on your skin. “I can’t be around this many kids sober.”

You let him steer you in the direction of the cooler box outside, where he takes and opens a bottle of beer, before turning to you. You shake your head at his wordless question and he grabs a small packet of gummy bears that are meant for the kids. 

Tipping his beer in a sort of salute at your father’s childhood friend whom he is also acquainted with, he places hand on the small of your back now, fingers curling around your side, almost holding your waist. He walks out to the poolside and locates the egg-shaped swing chair furthest from the villa. 

Settling down in it, he quirks an eyebrow up at you when you stay standing. “What? Sit down.”

Your cheeks are rosy as you mumble, “It’s too small.”

Sukuna glances at the space next to him. 

The chair is designed for two people, sure. But with his size, he might as well occupy it alone. 

Yet he scoffs and grabs your wrist, tugging you forward. He has a certain glint in his eyes when he promises, “We’ll make it fit.”

You gasp when he turns you around with his hands on your hips, pulling you down to sit on his lap. You turn around to gape at him, only to see him already leaning back as he takes a swig of his beer. He raises his eyebrows at you playfully. 

“Cozy, huh?” 

You immediately burst into flames. He chuckles. You’re so fucking cute every time you blush around your favourite uncle. 

“Here.” He hands you the packet of gummies. “You can give me the yucky orange ones like you always do.”

“They’re not yucky,” you mumble in embarrassment even as you open it. 

He laughs. “Yeah? You eat them, then.” He rolls his eyes when you stay quiet, head low and the tips of your ears red. “See. You hate them.”

As you feed yourself a red gummy bear, you look up and tell him, “I do but it isn’t because they’re yucky.”

“Yeah, whatever,” he says with another playful eye roll. 

You’re too embarrassed to say anything else, so you stay quiet. Sukuna doesn’t break the silence either. Feeling a little awkward, you shift on his lap as you look around, watching your brother make a cannonball into the pool. His friends follow.

Sukuna feels you move again, shifting your weight slightly. “You comfortable on my lap, kitten?” 

You turn to him, surprised. Shyly, you confess, “I’m too heavy, Uncle Kuna…” 

“Tch. You think these muscles are for show, or what?” He pats the inside of his other thigh, his fingers brushing your skin as he does so. “I barely even feel you sitting on me.” 

“Are you sure…?”

Sukuna rolls his eyes as he sits up, his chest brushing your arm, his handsome face close to yours. You can smell the beer in his breath, even feel the glance he makes to your lips chewing on a gummy bear. 

“I could carry you and throw you around like you weigh nothing, doll. If you want me to really feel your weight, I suggest you sit on my face.”

Your breath catches in your throat. You stare at him, eyes round. Did you hear him correctly?

His eyes narrow on your disbelieving features for a moment before he cracks up with a chuckle. You let out the breath you’re holding, glad he’s just making a joke. 

A very inappropriate one at that, but at least you know he’s kidding. Until he says, 

“Just joking. Bet you’re still light as a feather when you’re riding my face.”

Sukuna’s lips stretch into a grin at your speechlessness. Especially when you swallow almost loudly in the stunned silence that follows. 

“So cute,” he breathes, his beady red eyes flickering down to your parted lips again. “Never been dirty talked to before, huh?”

You’re still sitting frozen on his lap, gawking at him like a dead fish. He chuckles quietly, head turning slightly so his warm breath caresses your ear shell. 

“I’ll tell you what else Uncle Kuna can do to you,” he whispers in a low, sultry voice. “I could carry you and fuck you midair with no support. With you facing me and your arms around my neck. My hands on your thighs.”

He drags the tips of his fingers up the side of your thigh now, pulling back the hem of your dress in his wake as he reaches the curve of your ass. His fingers trail upward, letting the skirt of your dress fall back into place, as he cups your waist. 

Sukuna keeps sliding his hand up until he reaches your chest, where he stops. You’re not breathing anymore. Especially when he cradles your tit in his big hand. He moans softly in your ear. You mirror the sound he makes when he gives your breast a gentle squeeze. 

“Yeah, I know you’ll like that, baby,” he coos in your ear. Hand now fondling your tit, he continues, “Uncle Kuna could go all night, kitten. Worship your sexy body. Lick your pretty cunt. Fuck you like I’m dying tomorrow.”

You shift on his lap, and not because you’re uncomfortable this time. But because you have to squeeze your thighs together to keep your pussy from throbbing. 

Sukuna’s thumb skims the hem line of your bustier, caressing the soft skin of your chest. You feel your uncle leaning in closer, his nose touching your ear lobe as he groans quietly, only for you to hear. He gives the plush flesh another squeeze. 

“So fucking perfect,” he whispers. “You’d let me suck on them, won’t you, pretty doll?” 

You let out a heavy breath as you bob your head. You can feel the smile curling on Sukuna’s lips. 

“You think about Uncle Kuna when you’re touching yourself?” 

You swallow. You’re not sure why you feel like you have to be honest with him, but you are. 

“Sometimes,” you whisper. 

He clicks his tongue. “Tsk, tsk. Naughty girl.” He brushes your hair away from your shoulder and lowers his head to drop a hot kiss there. “What do you imagine me doing to you?”

Your mind is spinning, wondering if you’re in a dream right now. Why is your uncle asking you such questions? And more importantly, how do you even answer him?

How do you tell him that you imagine him between your legs, eating you out like a starved man with his thick fingers buried in your cunt?

Or that you think about kissing him while riding his thigh until you cum? 

It’s sick. And it’s meant to stay a dirty little secret that will follow you to your grave. 

But Sukuna wants to hear what his shy, pretty niece thinks about when she touches herself. 

“Tell me,” he croons. “Do you think of Uncle Kuna’s mouth on your pussy?” You nod your head breathlessly. He grins. “Yeah? I do give very good head.” 

You don’t say anything. Afraid to. Unsure if you should. 

“Wanna try?” 

You peek a glance at your uncle now and your breath catches in your throat at the heated look in his eyes as he gazes at you. His red orbs are scorching with temptation and desire. 

At that moment, you hear faraway clapping and the distant voice of your father shouting for everyone to gather for the cake cutting for your brother’s birthday. 

As if that has broken you out of the spell Sukuna has casted, you quickly stand from his lap, turning to face him, your face red and eyes wide.

He stares up at you, a lazy smirk on his face, eyes teasing. He eases back slightly to see you better. 

“We have to go in, Uncle Sukuna,” you murmur, sounding so out of breath that Sukuna finds it endearing. 

He rests his palm on the side of your thigh, sliding it up to the curve of your hips. He can see you holding your breath, your pupils blown as you watch him. 

“Go ahead, kitten. Uncle Kuna will be right behind you.”

-

"but it is his room," suguru mused. dexterous fingers slipped between your legs as you tried to reply, fingertips gliding along the lacy fabric of your panties, applying just enough pressure to distract you.

"or maybe you wanted him to see us. you have your own room, don't you? we could've gone there instead."

you shook your head lightly and smacked your dry lips in an attempt to find some words for him, but all you achieved was a low groan as the motion sent a wave of dizziness through you. maybe if you had more awareness you would have reminded him that he was the one who led you here. he was the one that got you drunk and then wrapped an arm around your waist, tugging you into his side and leaning down to your ear so he could ask if you wanted to go upstairs with him.

suguru had always been aware of your little crush, you really couldn't have been more obvious. so he already expected it when you nodded dumbly and stumbled along behind him, straight into your brother's room.

and now your skirt is bunched around your hips with your shirt tugged up high enough to let your tits fall out. those lace panties you'd chosen specially for suguru have been rudely yanked to the side, giving satoru a clear view of his baby sister's pretty cunt being stuffed full of his best friend's fingers.

"fuck, she looks so tight." satoru's breathless, his stiff cock resting in his hand as he jerks himself off to the sight in front of him.

"she is," suguru hums, scissoring his fingers in a way that makes you squirm, a small whine tumbling out of your throat. "poor thing can barely handle this, i'm not sure i'll fit."

he speaks with amusement because he knows that no matter what, you will take him. he’s been imagining what it'd feel like to be buried inside his best friend's little sister for so long, he can’t keep himself from you anymore. especially because suguru was only restraining himself out of fear of what satoru might think.

and then he found out just how depraved his friend really is when he walked in on satoru stroking his cock, a dirty pair of your sleep shorts pressed up to his nose.

he tried to play it off at first, but suguru knew they were yours, he'd seen you in them countless times. such a cute pair, they always gave him the perfect outline of your pretty pussy when you'd bend over in them.

your eyes drift between suguru and satoru, but you can't make out what they are saying. their words sound muffled, muted by the ringing in your ears and the bass from the party still going on downstairs. though it hardly matters. even if you could hear what they were saying, the only thing you're able to focus on now is the uncomfortable feeling pooling low in your stomach.

your hands scramble to claw at suguru's arm, your brows pinched together with an expression as close to a look of concern as you can manage. "w-wai… sugu," you breathe.

suguru gives you his attention, more curious as to whether you'll be able to form the words you want than what you actually have to say. his fingers slow to a languid rhythm, his thumb hooking around your pelvis to rub lightly against your clit.

after several failed attempts to communicate where your sentences were cut off by a loud moan and a twitch of your hips, you finally manage three little words, "n-need to go."

"go? you don't wanna be here with me?" the fake hurt in suguru's voice registers all too real in your hazy mind and panic strikes in your chest once more.

you'd never want to upset suguru, you care about him too much.

"bathroom…" you whine as you make a pathetic attempt to push suguru's hands away. it’s the best explanation you can offer at the moment.

he doesn't budge an inch, but the pitiful sight of you causes the corners of his lips to quirk up, similar to the way satoru's cock twitches in his grasp.

you're just coherent enough to know that what you're feeling is wrong. as suguru touches you, you're not experiencing the the normal pressure of an impending orgasm. instead, it's a worrying pressure that makes you try to wriggle out of suguru's grasp.

he knows exactly what you're feeling.

your bladder is so full that it's starting to ache. you're past the point of being able to completely hold it in and the once creamy slick that coated suguru's hand has turned watery. it’s louder each time he plunges his fingers back into your tight heat, and messier as the wetness starts to splash onto his wrist.

with your heart racing in your chest, you make one last futile attempt to persuade your brother's friend to let you up so that you can make a run for the toilet. "s-stop! please i—."

"fuck, i'm so close. keep going," satoru interrupts. his cock is throbbing in his palm, his pupils are blown so wide you can hardly tell the color of his irises.

it's already bad enough being forced to endure whatever suguru wants to put you through under your brother's heated gaze. but that embarrassment reaches impossible heights when suguru plunges his fingers deep inside your sopping cunt one last time, using his other hand to press down onto your stomach until a steady stream of piss is leaking out of you.

satoru is ruined. the moment he sees the glaringly obvious look of shame on your face, he can't stop the obscene moan of your name that slips past his lips as he shoots thick ropes of cum into his hand.

he knows that he's beyond fucked up for this. he can try to reason with himself that it wasn't his idea and that makes it better, but he knows that's a lie. at the end of the day, he just cared about getting to see his best friend humiliate his little sister more than anything else, and there's no salvation from that.

but you just look so pretty with your cheeks flushed red, your eyes glassy with tears as you look anywhere but at them. you can't bear to meet their eyes.

"such a messy girl… just like your brother." suguru stares at the way satoru's cum is dripping onto the floor of his room as his cock softens in his hand. it's nothing compared to the near puddle that you've made on the bed.

your skirt is soaked through as you remain held in place, laying in your own pee as suguru finally slips his hand out of your sore pussy.

you hate them both.

you hate that you trusted either of them to take care of you.

you hate that there was an inexplicable swell to your ego when you saw how hard your brother came just from watching you.
