Seishiro is stuck in a limbo of apologizing and holding his ground. Your angry tears frustrate your usually apathetic brother to no end, his mind occasionally rolling the tape mid game of how you had stood there, actually getting annoyed with him.
He can admit that the chores in the house definitely tend to land in more of your responbilites, but its not really his fault if he didn't know that it bothered you in the first place. The whole blowing up on him was kinda uncalled for.
It’s coming around to midnight now. Sometimes on the weekends you would have little sleepovers in his room, but it’s clear now that won’t happen. It’s hard to drag himself into bed so early when his favourite pillow isn’t there-- your chest.
He drags a hand over his face as the fifth lose screen of the night pops onto his game, groaning. “Such a hassle…”
Within minutes he finds himself at your door, peeking through the crack before letting himself in. Your form is curled up on the bed, clad in panties that revealed the curve of your ass, and a loose shirt he could only assume was stolen from his laundry— flipped up just enough to showcase the delicate curve to your spine.
The bedside light is still on and your hand rests over your phone, asleep in a bed that is still made from this morning. The sight is nothing short of tempting,
The bed dips under Seishiro’s weight, spooning himself over your sleeping form like a koala, one arm draping around your front.
You squirm under the added weight, pressing your face into the blanket. “Seishiro-niisan..” you mutter groggily, blinking at the suddeness. His hips slot against your ass, nose nuzzled into your hair as he begins a slow grind of his clothed cock into the plushness.
Lamely, your hand reaches out to his side, a sorry attempt to push him off. “Mmh.. Stop it.”
“Sorry, ‘mouto,” His sheer size has you pushed onto your stomach now, pinned down while your big bro lazily ‘cuddles’ you. “For making you cry..”
Your eyebrows knit together, catching your lower lip between your teeth. Trying to writhe away only makes it harder for yourself, unintentionally meeting his needy ruts. Bitterness and relief wells up in you, forced to take his apology.
“What're you doing..” you whimper into the sheets, your panties sticking to your wet cunt at the friction.
He nods, reaching down to tug his sweats down just enough to free his leaky cock, using the head to nudge away the fabric covering you.
The initial graze of your chubby pussy against his sensitive head pulls a throaty moan from him, bucking against your slick folds, tip catching at your throbbing clit.
Your hips buck into his, a surprised whimper of pleasure slipping past your lips. “Aniki,” you gasp.
A quarter of his cock is coated shiny in your juices, his precious sister’s pussy only drooling for more. This was the kind of cuddles he missed, depriving himself of your accessible cunt just because he was being stupid…
“Gonna fuck you now, imouto..” He warns lowly, lining his tip up to your tiny hole, holding you tighter to prevent anymore squirming. “Gonna cum in you.”
“No, wear a condom,” your gasp is somewhat slurred, biting your cheek. Your big brother ignores your plea, his bare cock begins to push into you, a cry sputtering from you at the stretch. Condoms are tucked into the drawer of your bedside, collecting dust since purchase. No, its too far, too much of hassle. Hes already inside anyway.
You can make out the faint pants above you, feeding one inch, then another, stuffing his cock without going easy into the tight fit.
“More, more...” Nagi whines, seated within your honeyed warmth before he begun to roll his hips. The pain of his length filling your cunt twisting at your face, squeezing your eyes shut. Strong arms sneak under your frame, back pressed to his chest as he begins to languidly fuck you.
Your mouth opens yet no sounds come out besides a choked, broken cry, creaming around your big bros fat cock. There’s nothing you can do to dampen the pleasure, toes curling as his hips slap in rhythm to your ass, adding a beat to Nagi’s lazy way of apologizing-- by violating his little sis.
“I'll do more around the house, kay?” Seishiro moans, his lips finding your damp hairline with a gentle fervor. A mop of white hair tickles just beneath your brow, lanky fingers pressing into the soft of your stomach, dragging up to play with your breasts. He rolls one peaked nipple between his index and his thumb, pinching just to hear you squeak— unable to brush away from the incessant stimulation.
It was nice how perfect your tits were in his hands like this, the weight squished warmly against his palms.
“No you won't,” Drool gathers at the corners of your mouth. “I don’t forgive you.” The neglected pearl between your thighs aches and throbs, saved by the fricton of the blanket, soaked with your desire. A knot builds where the fat bulge of Seishiro's dick imprints, holding your breath to focus on cumming.
“You’re a hassle when you want your big brother’s cock…” He sighs at your protest.
Your walls flutter around his length in return, confirming his suspicion. The teen took in the sight of his little sister, your hair a mess of strands sticking to a sweat-soaked forehead, body arching off the bed with every deep penetration. The way you writhed and squirmed uselessly beneath him, each plunge of his cock into your tight cunt blurring the memories from earlier.
His cock swelled with need, and he knew he was close to filling you with his seed. The hung length twitched within your velvet walls, his thrusts growing shorter and harder that smother your body, squeezing your tits as leverage. Nagi groaned into your hair, spilling hot ribbons of cum deep inside you.
When your left panting and pulsing around nothing, shooting daggers with that glare over your shoulder, he can only smirk in contentment at the pretty mess. His pleasure leaks out of your hole, smeared with the fabric of your panties.
