It’s your nineteenth birthday and while you had a wonderful party with your family, you still feel so young and small. Your brothers are both attending colleges for their own career paths, but you’ve just got out of high school and have no idea what you want to do! You’ve been babied by your brothers, so you don’t have a clear view of the future for yourself that doesn’t include Atsumu and Osamu by your side.
One thing bothered you though: you were still a virgin. Thanks to your brothers, boyfriends were a foreign concept to you. All your friends lost their virginities before their birthdays, but your last friend lost her virginity on her birthday, a present from her boyfriend. You were slow to coming to the party and you told them you’d have lost it by the time your birthday came around, even getting a boyfriend!
A boyfriend quickly discarded by the brooding brothers of yours. A sneer from Atsumu and a glare from Osamu had his tail between his legs. Truly, a shame. You knew your friends would tease you again for the lack of a boy in your life, so you decided to, uh, pretend. A dildo was similar to a penis, right? That’s why they existed.
You didn’t know it’d be so hard! You have to have an orgasm to properly lose your virginity, that’s what your friends said. Pumping the silicone piece into your tiny cunt was harder than expected, only fitting half in before you started to pump it. It sent a tingling down in your tummy, but it was more effort than expected. Noises or frustration mingled with your forced moans, whining as your wrists started to hurt.
Osamu was doing his homework when he heard you make a noise of frustration, huffing and puffing. He didn’t pay too much attention to it, but then you made a similar noise. So, time to investigate. He wouldn’t want you to exert so much energy, you’re his baby sister! He expected to see you trying to get something off a high shelf, your shirt riding up to show your smooth stomach or you to be under your bed, shorts-clad— even better, panty-clad rump in the air. He did not expect to see you on your bed, legs spread and pumping a pink silicone dildo into your cunt. If only that was his—
“‘Tsu- ‘Tsumu,” you moan out, biting on your lower lip. Osamu’s mouth drops into a frown, growling at his twin’s name dropping from your mouth. You turn to look at the door, suddenly opened only to be slammed shut.
A startled gasp makes him stop in front of you, eyes burning with an unknown desire. “‘Samu! What’re you doing?” He just looks at you, eyes glancing at your hand still between your legs. Your eyes go down, shame burning in your face. “I’m trying to be a big girl. I wanna lose my virginity,”
“Why didn’t ya ask me?” He asks, putting his weight on your bed. You panic and close your legs, moving the dildo out of you. “And why ya callin’ out ‘Tsumu’s name? Huh? Am I not good enough?”
“N-No! That’s not it! ‘Samu, you’re scaring me!” You cry out, his large hands spreading your legs. Your puffy pussy is fully on display for him, his eyes noticing the lack of slick. “Don’t hurt me!”
“I’m not gonna hurt ya. I’m gonna help. Wanna be a big girl? I can help,” he says. He doesn’t move, though, waiting for your permission. Even though you’re hesitant — he’s your brother! You’re nodding your head, fingers soon finding themselves in Osamu’s darkened hair. He stopped dying it, so it’s completely natural again. His face is buried in your cunt, lapping at your folds as your moans aren’t forced, head thrown back as Osamu tongue fucks you. When he sticks two fingers into you, he doesn’t expect you to be so wet, a drastic difference from moments ago. He moves to wrap his lips around your clit, walls tightening as you finally release on his fingers and face.
When Osamu comes up, he’s licking his lips while you pant. “Did.. did I lose my virginity?” You ask him, tears clinging to your lashes.
“What d’ya mean?” You explain what your friends told you, all while he strips off his shirt and peppers kisses on your stomach, rising your shirt up as he does. “Nah, I gotta cum inside if you wanna lose it. You gonna let me do that?” The no hesitation in the nodding of your head has him grinning, straightening himself as he rubs his hardened cock through his pants. Today, fantasy becomes reality. “Alright, I’ll go slow,”
Even with his slow sinking into you, you’re gasping and clinging to his biceps for dear life, tears staining your pillow as he splits you open. He’s far bigger than the dildo, but the slick from your orgasm makes it much easier for him to slide in. He kisses your cheek, telling you how good you are. It’s the little praise that has you encouraging him to keep going, and he does. He keeps pushing in until he’s bumping against your cervix, almost completely inside of you. Your legs tighten around his waist, keeping him locked against you.
“Don’t worry, lil sis. I’m not goin’ anywhere,” he shushes, brushing your tears as he stays still. An occasional hiccup has his heart hurting, but he knows you’ll feel good eventually. Well, even if you don’t, he’ll start. When your legs loosen, dropping back to the plush bed, he starts moving. He’s still slow, spreading your walls for his thick cock as you continue to adjust. It’s not until you’re begging him for more does he pick up the pace, slamming his hips against yours. He has to cover your mouth so you don’t alert the whole house he’s fucking you, your screams of pleasure coming out. They’re muffled, but he can hear how much you’re enjoying it. It urges him to go even faster, grunting as he chases his own high.
Another screams rips from you, walls tightening as you cream on his fat cock, eyes rolling as toes curl. It’s enough to send Osamu over the edge, groaning as he buries himself even deeper inside, pumping you full of his cum, you milking every drop. He kisses you, your panting mouth perfect for him to give you a passionate kiss, staying deep inside you. He breaks the kiss, “I love ya, little sis,”
“Love you, too, nii-san,” you smile, kissing him again.
It’s all you ever wanted, to be a big girl. It also brings you and Osamu closer together, you often bouncing around the idea to help him in his shop once he gets it set up. When you go into his room, the door locking behind you, you miss the way Atsumu glares. He has a feeling you’re not studying with Osamu, but there’s nothing to suggest otherwise.
Well, when Osamu is late from coming back from college, Atsumu is the only one home. It’s a small breath of fresh air, relaxing his tired muscles after a long practice match. When he hears small grunts and moans from your bedroom, he goes to investigate. You shouldn’t be home, let alone have anyone with you. The creaking of the floorboards doesn’t stop the noises from your room, Atsumu’s curiosity spiking. Peeking into your open door, he sees you on your back, legs spread open as your laptop plays an obscene video, the moans and grunts coming from the speakers. Your occasional moan is muffled by the shirt hem in your mouth, but it’s dropped when you moan out Osamu’s name, eyes rolling back as your fingers work on your clit.
Atsumu glares at the mention of Osamu’s name, shutting the door that has you jumping and struggling to explain yourself. “Ya think ‘Samu’s better than me? Is that it?” They’re so similar, it’s striking. The hungry eyes, full of anger and lust, they look so much like Osamu’s, but the light blond hair reminds you it’s Atsumu. “What’re you- Yer watchin’ sibling porn? Thinking of your big brother? ‘S that it?”
“No, it’s not what you think, ‘Tsumu!” Unlike Osamu, Atsumu’s one to take what he wants. He moves the laptop off the bed, spreading your legs as you squirm and struggle. “Lemme go!”
“Brats like you need to be put in place, don’t’cha know? You’re fucking soaked, getting off on your big bro that much?” You’re crying and still trying to kick him off, but it just turns him on even more. You’re still innocent and so naive in his eyes, it’s nothing for him to just take that from you. His cock is already hard, begging to sink into your warm depths. “You gonna let me fuck you? It’ll be like that video you were watching,”
You’re shaking your head, pushing at his chest as he leans down to press kisses to your neck. “C’mon, lil sis. I’m not gonna hurt ya. You trust me, right?” It’s a question that has your movements stopping, glossy eyes looking at Atsumu. He’s smiling, your big brother not showing any hint of malice. You sniffle, his thumbs swiping away the silver droplets on your cheeks.
“As long as you promise not to hurt me, okay ‘Tsumu?” You ask him, big doe eyes of innocence as you look at him. He grins and kisses your lips, licking your bottom lip. A whispered breath of ‘wouldn’t dream of it’ is all you hear before his mushroom head is pushing at your entrance. He’s just as big as Osamu, but it’s still hard to take in. You’re nice and slick, though, Atsumu notes. All from watching some incest porn, it’s almost funny to him how all you had to do was ask, no reason to hide it! Him and Osamu have been dreaming of keeping you all to themselves, there’s no reason for you to hide your desires.
Once he’s bottomed out, he doesn’t let you adjust, immediately pulling out to thrust back in. It’s sharp and rough, knocking the air from your lungs as your head gets thrown back. Atsumu’s quick to attach his lips to your neck, sucking the flesh and digging his teeth into the skin. It’s a way to show he’s claimed you, as if he doesn’t plan on coming inside. That’s his goal — mark you inside and out. With your arms above your head, grasping the pillows, there’s no reason for him to not. Licking his thumb, he presses it to your clit and flicks it, sending shockwaves through you as you scream and cream around his cock, thighs tightening around him. He’s not too far behind you, rutting against you as he paints your insides white, sending you into another orgasm, juices spraying against his abdomen.
“Lookie there! You just squirted all over me,” he chuckles, rubbing your shaking thighs. You’re overstimulated, so he doesn’t push another round. There’ll be time for that later.
A week later, you find yourself in a dilemma when your clothes won’t fit. Worried about gaining weight, you confide in your big brothers who give you a test. “Just pee on it. It’ll tell you if you’re overeating,” they said. They’ve never lied to you before! When those two lines pop up on the plastic tool, you show it to them, confused. They tell you you’re pregnant, but then comes the question. Who’s the dad? Really, does it matter? They have a lot of love to give you and they’re twins. Your child is gonna look like both of them no matter what.
