“How’d’ya like the show, Tsumu?” Osamu asks.

Your head jerks around to see Atsumu standing across the room, palming his cock through grey sweatpants.

“Oh, it was great,” Atsumu says. “Liked that part at the beginning. Something about taking us both at the same time?”

“U-uncle Tsumu!” You exclaim, still sitting on Osamu’s softening cock.

“What is it, doll? Tell Uncle Tsumu what ya want,” Atsumu says, coming up behind you. His hands run down your sides and back up your shirt, cupping your breasts.

“Want Uncle Tsumu to fuck me,” you breathe, bucking your hips as he pinches your nipples. Osamu hisses from the overstimulation under you.

“Yeah? Ya want this?” Atsumu asks, moving one hand to grab his bulge. You nod.

“Want you to fill me up, too, Uncle Tsumu,” you say, rolling your hips. Osamu’s cock twitches deep inside you, beginning to harden again.

“Want me to cum inside yer ass while Samu fucks yer cute, little cunt? Ya said ya would take both of us, doll,” Atsumu says, twisting your nipple. You moan lightly and grab Atsumu’s forearm.

“Wanna be full,” you moan as Osamu bounces you lightly on his fully hard cock.

“Is daddy not enough for ya, doll?” Atsumu asks, pulling your shirt off and tossing it across the room.

“Tsumu,” Osamu growls, squeezing your hips tighter.

“Daddy fills me up so well,” you say, running your hands down Osamu’s muscular chest. Osamu thrusts into you hard, pulling a broken moan from your lips.

“Stop hoggin’ her,” Atsumu says, pulling you up and off of Osamu’s cock. You let out a gasp at the sudden emptiness. Osamu’s cum pours out of you, running down your thighs and your eyes burn.

“Daddy!” You cry, reaching out for him.

“She’s not a fuckin’ toy, Atsumu,” Osamu sneers. Atsumu rolls his eyes as he carries you to his room.

“Are ya comin’ or not? How are we both supposed to fuck her on the couch?” Atsumu calls.

“Damn it, Atsumu,” Osamu swears, tucking his wet cock into his pants and following.

“Feel empty,” you pout. Atsumu lays you on his plush mattress gently.

“Don’t worry, doll, I’m gonna fill ya up real nice,” Atsumu says. He spreads your legs wide before pushing them up to your chest, revealing your messy cunt. Osamu’s cum oozes out of you, running down to Atsumu’s sheets.

“Daddy,” you whine as Osamu appears next to Atsumu.

“What is it, baby girl? Tell daddy and Uncle Tsumu what you want,” Osamu says. Atsumu catches the cum leaking out of you and slowly pushes it back in. You let out a small moan.

“I think I want her sloppy cunt, ‘Samu,” Atsumu says, sliding two fingers in you.

“Uncle Tsumu,” you moan as he scissors his fingers, needlessly stretching you out.

“Why don’t ya prep her ass, then?” Osamu suggests, pulling his shirt off. “Bet her little hole is so tight. Ya got lube, Tsumu?”

“Middle drawer,” Atsumu says, pointing at his nightstand. “Bet I won’t need it. She’s so fuckin’ wet, she’s makin’ a spot on the sheets.”

Atsumu pulls his fingers out with a lewd, squelching sound and presses one finger against your tight asshole.

“Ts-Tsumu,” you choke as he slowly pushes his pointer finger in. “H-hurts so good.”

“She’s so fuckin’ tight,” Atsumu grunts. “She’s suckin’ my finger in like a slut.”

“Relax, sweetheart,” Osamu says, squeezing your thigh as he hands Atsumu the lube. “Lube. Now.”

“I think she likes the pain,” Atsumu says. “Is that right, doll? You like it when it hurts.”

You nod. The burn only makes everything feel so much more sensitive, and before long you’re fucking yourself on to Atsumu’s finger, begging for more.

“More, want more, Uncle Tsumu,” you whine, grinding your hips down, trying to get more friction. The burning is all but gone and you find yourself missing it.

“Do ya want the lube, baby doll?” Atsumu asks. You shake your head.

“Wanna feel you,” you say.

“Are ya sure, baby? I don’t want you to hurt too bad,” Osamu says.

“Wan’ it to hurt,” you moan. “Feels so good.”

Atsumu breathes deeply before slowly adding another long, thick finger. You let out a high-pitched moan, fisting Atsumu’s white sheets tightly.

“Fuck, she’s so tight,” Atsumu groans. “Almost wanna fuck her just like this.”

You clench around his fingers at the thought of him taking you with barely any prep. Your virgin hole stretching around his cock, with only Osamu’s cum and his own precum as lube. You moan as Atsumu scissors his fingers, stretching you out.

“Ah, she likes that,” Atsumu says. “Ya wanna take my cock just like this? Feel it for days, doll, ya wouldn’t be able t’ sit without feelin’ me.”

“Wanna be full,” you whine. You moan as Atsumu roughly twists his fingers deep inside you.

“Samu, why didn’t ya tell me yer little girl was such a pain slut? Look at her, practically beggin’ me t’ fuck her dry,” Atsumu sneers. He adds a third finger suddenly. The new stretch knocks the breath out of you, your back arches off the bed and you gasp as Atsumu quickly pumps his fingers in and out of you.

“Hurts,” you moan. Your eyes roll back as Atsumu gathers spit in his mouth and spits directly into your hole.

“Aw, the little baby can’t take it, huh?” Atsumu coos, using his spit as lube.

“Do ya need lube, sweetheart?” Osamu asks, staring down at you worriedly.

“She can take it,” Atsumu says, fingers not slowing down. “Look at her, practically fuckin’ herself on my fingers.”

Your hips were meeting his fingers with every thrust. The stretch was burning all the way to your core and your juices were mixing with Atsumu’s spit, lubing his fingers in the process.

“She likes it so much, she’s creamin’ around nothin’,” Atsumu says. “Rub her clit, Samu.”

Osamu rubs his fingers through your wet folds before rubbing figure-8s over your clit.

“Oh!” You gasp, back arching. “More, more, please!”

Atsumu leans down and licks over your hole boldly before adding a fourth finger.

“What a slut, taking four fingers with no lube,” Atsumu sneered. “Bet ya could take my whole fist, isn’t that right, doll?”

“Atsumu,” Osamu warns. “Shut the fuck up before I end this.”

“Daddy, ‘m close,” you whine, walls clenching around nothing. “Wanna cum!”

“Go ahead, baby,” Osamu says. “Cum for daddy and Uncle Tsumu.”

You cum with a loud cry. Neither twin slows down, milking every last second of your orgasm. Your thighs twitch with overstimulation.

“I think she’s ready,” Atsumu says, pulling his fingers out. You whine at the empty feeling.

“Fuck me, please, I want it so bad, daddy, Uncle Tsumu,” you beg.

“You heard the princess,” Atsumu says. “How do ya want to do this?”

“Want daddy to hold me,” you say.

“I’ll be on bottom, then,” Osamu says. He leans against Atsumu’s headboard and pulls you on top of him, legs splayed out over his thighs. “Ya gonna be a good girl and take us both?”

You nod as you lift your hips. Osamu drags his cock along your slit. You moan as his cock catches your hole.

“Fuck me, daddy, please,” you whine, bucking your hips. “Please, I want you in me.”

Osamu lines his cock up with your hole, “Go on, sweetheart, take what you want.” You slowly sink down with a low moan.

“So good,” you breathe. “So deep in me.”

“Ya ready for me, princess?” Atsumu asks. His bare chest is warm against your back and you can feel his cock pressing against your ass.

“Please,” you say, arching your back slightly. “Wreck me, Uncle Tsumu. Make me hurt.”

“Fuck, yer sayin’ just what I want t’ hear, princess,” Atsumu groans. The fat head of his cock presses against the rim of your asshole. “Ya want it t’ hurt, huh? What’s the matter, daddy doesn’t give it to ya hard enough?”

“Yer a dick, Tsumu,” Osamu snaps.

Atsumu ignores Osamu as he pushes the head of his cock past your rim. You gasp and jerk forward unintentionally. Atsumu clamps down on your hips with an iron grip.

“Nah, princess, ya said ya wanted it t’ hurt,” Atsumu says. “I’m only givin’ ya what ya wanted.”

“Atsumu,” Osamu warns. You shake your head as tears burn at your eyes.

“More,” you grunt. “Hurts good.” You were more stretched than you’d ever been and Atsumu was barely in. Any pain you would’ve felt was washed away by the excitement of having both twins seated deep in you. You could already see the way your lower tummy would bulge once they were both balls deep. A shiver of excitement ran up your spine.

“Daddy’s so soft with me,” you say, slightly pushing back on Atsumu’s cock. “Want someone to fuck me until I’m broken.”

“Oh, I’m about to fuck ya until yer dumb, princess,” Atsumu says. You can hear the smirk in his voice.

“Daddy’s gonna remember that, little girl,” Osamu whispers in your ear. Your walls clench around him at the thought of punishment.

“Might wanna hold her still,” Atsumu says, slowly sliding out. His grip on your hips hasn’t loosened and Osamu wraps his arms around you, holding you firmly to his chest. Atsumu leans down and presses a small kiss right below your ear.

“Still want it t’ hurt?” He asks, lips brushing against your earlobe. Before you can say anything, Atsumu’s cock is buried in your ass in one, quick movement. You lurch forward, trying desperately to escape the painful stretch. There’s no relief in the motion since you’re caged in by identical iron grips.

You let out a squeak of pain as tears cascade down your cheeks.

“So pretty when ya cry, princess,” Atsumu says, turning your head to the side. “I thought ya wanted it t’ hurt?”

You swallow a sob before you can reply. “S-so full, Uncle Tsumu. Gonna tear in half.”

“She’s fuckin’ chokin’ my cock,” Osamu moans. “She liked it. Her walls are just milkin’ me.”

“I told ya, ya had a little pain slut on yer hands,” Atsumu says. “She’s clenchin’ me so tight I can’t pull out.”

“Let her adjust a little, Tsumu,” Osamu says, “she’s already cryin’ like a little baby.”

“‘m not!” You protest, burying your face in Osamu’s chest.

“Oh, princess, ya shouldn’t’a said that…” Atsumu says. His hands tighten on your hips. “‘Cause if yer not cryin’, well then, I’m just not goin’ hard enough, am I?”

You hiss when Atsumu pulls out of you slowly.

“No, no, ‘m sorry, Uncle Tsumu!” You cry. “I’m crying!”

“It’s okay, sweetie, daddy’s got you,” Osamu says, holding you tightly.

Atsumu slams into you with a near thunderous clap . Your back arches as you dig your nails into Osamu’s stomach and you let out a loud yelp.

“Ts-Tsumu!” You cry as he pounds your ass relentlessly. The intense pain brings more tears to your eyes. Atsumu reaches around and roughly grabs one of your bouncing breasts.

“What’s the matter, princess? Too hard for you?” Atsumu grunts, rolling your nipple between his pointer and middle fingers. You moan loudly.

“Hurts!” You exclaim. “So good!” A sob wracks through your body. Atsumu moans as you tighten around him.

“What a pain slut,” Atsumu says. You nod as you cry. Osamu gently thumbed your tears away, pulling you down for a soft kiss.

“Yer such a good girl, takin’ us both,” Osamu whispers.

“Move, daddy, please,” you beg. Atsumu’s hard thrusts were pushing Osamu’s cock deeper in you but you needed more.

Osamu’s hands wrapped around your sides as he lifts you slightly off his cock. You whimper as Atsumu’s cock abuses you at a different angle. Osamu’s slow, deep thrusts were just enough to cancel the persistent pain caused by Atsumu’s hard and fast ones. You threw your head back in ecstasy as the twins fell into a brutal rhythm.

“Daddy,” you moan, hands running up Osamu’s thick chest. Atsumu grunts and twists your nipple. “Tsumu, ‘m so full.”

Your hand drifts down your own abdomen, tracing around the bulge where Osamu was seated deep in you. You moan before letting your fingers drift a little more until they reach your clit.

“Gonna cum,” you whimper as you rub the sensitive nub. Your legs twitch from all the stimulation.

“Go ‘head, baby, cum for daddy,” Osamu says.

Atsumu knocks your hand away, placing his own fingers over your clit, rubbing vicious circles around it. You moan loudly.

“Cum for me , princess,” Atsumu says. “Right. Now.”

You let out a high pitched moan as the coil in your stomach finally snaps. You gush around Osamu’s cock, walls squeezing around him as he moans.

“Fuck, squeezin’ me so tight, yer milkin’ my cock, sweetheart,” Osamu moans. His hips falter as his cock twitches deep inside you.

“Fill me up, daddy, please,” you moan, bouncing on his cock. “Want your cum in me.”

“Yeah? Want me to fill up yer slutty, little cunt?” Osamu asks. You nod. “Come ‘ere, sweetheart.” Osamu pulls you into a breathtaking kiss as he pumps you full of his seed.

“That’s enough o’ that,” Atsumu says. He pulls you up off of Osamu and into his chest. He easily manipulates your body until you’re face down in his mattress and your ass is up in the air. “Gonna fuck ya real well now, princess.”

“Fill me up, please, Uncle Tsumu,” you beg, arching your back. “Cum in me.”

“Fuck,” he swears. “Wanna cum in that sweet cunt o’ yers.”

“Please, please,” you moan as he continues to fuck your ass. “Want you to cum in my cunt.”

Atsumu looks at Osamu with the question written on his face.

“Go ahead, fill ‘er up, Tsumu,” Osamu says.

Atsumu pulls completely out, leaving your knees weak. He wraps one strong arm around you and plunges into your pussy.

“Oh, fuck!” Atsumu swears. “So tight, even after Samu’s filled ya up twice.”

“Fill me up, Uncle Tsumu,” you moan. “Cum in my tight, little pussy, please!”

“Whatever ya want, princess,” Atsumu moans. His hips stutter as you clench around him. “Fuck, gonna fill you up so good. You gonna cum for me again, princess?”

You nod as you reach down to play with your clit. “Want your cum in me, Uncle Tsumu,” you say.

“As soon as you- fuck!- as soon as you cum around my cock,” Atsumu says. “Want you gushing around me, milking my cock, princess.”

“So close, Uncle Tsumu,” you breathe. “Need more.”

Atsumu pulls out, flipping you over, before pounding back into you. He wraps his arms around you, lifting you into his chest. You moan loudly as he hits that spongy, little spot inside you head on.

“Cum on my cock, princess,” he whispers in your ear as you wrap your legs around him. You nod as he fucks you deeper than before.

“Fuck, fuck,” you moan, digging your fingers into his shoulders. You drag your nails down his skin as you cum hard, juices gushing, mixing with Osamu’s cum. “Please, fill me up, Uncle Tsumu! I need it, I need your cum in me!”

“Fuck,” Atsumu grunts as his cock twitches deep inside you. You roll your hips and your walls flutter around him as he paints them white.

“So, full,” you breathe as Atsumu fucks you through his orgasm. Your walls milk him until he hisses from overstimulation.

“Fuck, yer such a good girl, princess,” Atsumu says, laying you down next to Osamu.

You frown as you feel cum leaking down your thighs.

“It’s leaking,” you whine. “Wanna be full.”

Atsumu spreads your legs wide and leans down, licking a broad stripe up your messy slit. You gasp as his tongue pushes his cum back inside of you.

“Just gonna clean ya up, princess,” Atsumu whispers, pushing your legs up to your chest.

You clench around nothing, pushing his and Osamu’s loads out of your cunt. Atsumu licks it up with a low slurping noise.

“Come on, give me more, princess,” he says. He uses his thumb to rub circles over your clit. Your walls spasm from overstimulation.

“Tsumu!” You cry as you cum. Your juices squirt out, drenching his face.

“That’s my princess,” he praises, licking his lips. Atsumu wipes his face off before climbing up his bed to lay on your other side. “Come here, princess.”

You twist out of Osamu’s arms to face Atsumu. He grabs your chin gently and pulls you into a slow, soft kiss.

“I love ya, princess,” Atsumu mumbles, cupping your cheek. Your cheeks burn.

“I love you, too, Uncle Tsumu,” you say. Osamu’s arms tighten around you. “I love you, too, daddy.”

“I love you, sweetheart,” Osamu says. You yawn cutely and snuggle into the soft sheets below you. Atsumu yawns and tosses an arm around your waist.

“Next time, I get her cunt,” Atsumu says, closing his eyes.

“You’ll get what I give you, dumbass,” Osamu says.

“Bastard.”

“Bitch.”

You smile as the sound of the twins arguing fades as you fall asleep.

Next time…
