You seven are in the first year of high school. All of your year were shocked to see sextuplets, because this is rare. Still, you seven told no one about your relationship. The most people would think about you as a slut and the brothers don't want that, so they keep their mouths shut along with you.

Only your older sister knows about that, but she doesn't see that as a big deal. As long as you are happy and don't cry, she won't say a word against this.

But the sextuplets got really shocked after they picked you up from home. Since your parents took you with them on a vacation the whole holidays, the brothers weren't able to see you. On your first day at school they picked you of course up, but when they saw how big your chest grew they got a nosebleed.

When they asked you how this happens (it was Osomatsu since the others were too embarrassed) you just laughed flustered and said: "Actually, I don't really know too~. Seems like I'm a late bloomer~." When you touched with your hands your chest and moved them up and down while explaining the brothers how they just grew day after day, they needed to use the bathroom really bad. You didn't knew why, but you waited outside until they were done. Of course these six boys got hard and needed to take care of this problem. Not just that your chest grew so much, you looked too cute in the high school uniform that they couldn't take it anymore.

You walk with Osomatsu, because the others got hold up from other students and Osomatsu used this chance to be alone with you. "A movie?" You ask confused. Osomatsu hums with a excited smile and rubs his index finger under his nose. "Yep! I wanna lend a movie out and if you want ... we can watch it together y/n-chan?" You hum before nodding your head. "Sounds good. But what movie do you wanna watch, Oso-chan?" "You'll see~."

When you two arrive the video shop, Osomatsu suddenly stops you from walking inside. "Huh? What is it, Oso-chan?" "We need to change at first our clothes, y/n-chan." Osomatsu says so serious to you. "Aaaaand ... why?" You tilt your head confused to the side. "You'll see~. Now here, but this on and I'll change too." Before you can ask more, Osomatsu gives you some clothes and push you over to the public toilets near.

You chance into a light red dress who looks pretty feminine and wear a blue denim jacket over it. You step out of the restroom and are surprised to see Osomatsu already changed. But he wears a gray sweater, blue jeans and white sneakers. His hair is a bit messy too.

Both of you looking right now older than you are.

"And here we're hiding our schoolbags~." Osomatsu put your schoolbags under a few bushes, so no one can see it. You are even more confused, but wait what will happen next. "So, and now to the main part." Osomatsu takes your hand and pulls you with him back to the video store. When you two enter, Osomatsu walks over to the 18+ section. 'Oooh~! So that's why we should chance.'

~And then...~
The man behind the cash register didn't really looked like he care about your age and just gave Osomatsu the AV he choose. You were looking at all the other AV's and didn't seem to mind it. Much to Osomatsu's surprise. Now, you two are in your room and watch the AV over the laptop from your older sister on the floor. Of course you two listen to the voices over earphones.

Osomatsu press his legs together while pressing his hands down into his crotch. He glance over to you with a blush on his cheeks. You sit with crossed legs next to him while staring at the video. 'Isn't that turning y/n-chan on?' Osomatsu gulps when he hears the woman moan and reach a hand out to you. Osomatsu lays his hand down onto your thigh and- "Ah~!"

"Eh?" You quickly covered your mouth with both hands after you moaned from the touch. Osomatsu smirks before taking the earphone out. "Y/n-chaaan~?" You hum and glance shyly to the side. Osomatsu slide his hand slowly under the dress and pulls with his other hand your earphone out. "What was that~? Hmmm~?" You remove your hands, before knocking your legs together and clenching your arms around your stomach. Osomatsu hums confused when he sees your body starts to tremble.

"O-Oso-chan, I ... I feel weird inside." You mumble embarrassed out and glance away from him. Osomatsu smirks even more before lifting you up. You yelp before you fall on the bed and Osomatsu hovers over you. "That means you're turned on~." Osomatsu hums before slipping a hand into your underwear. You moan when he press his middle finger against your core. "Sorry y/n-chan, I didn't knew how wet I'm making you~." Osomatsu chuckles before slipping his finger inside. Your body twitch before you moan softly.

Osomatsu leans down and starts to kiss you deeply while bumping his finger in and out. You moan into Osomatsu's mouth, what he use to slip his tongue inside. Osomatsu adds a second finger and then a third one. You moan loudly before you cum onto Osomatsu's fingers. He pulls them out and pulls away from your lips. You catch your breath while Osomatsu licks his finger clean.

"Wanna feel how much you turned me on, y/n-chan~?" Osomatsu whispers in a low voice next to you ear, while zipping his pants open. You lay your arms around Osomatsu's neck and look really submissiv up to him. Drool running out of your mouth, tears welled up in your eyes, your face bright red and a bit sweat running down. "Do you have a condom, Oso?" You ask panting softly. Lust clouded your eyes. Osomatsu smirks weakly before taking one out of his pocket.

He rips it open and- "Hm?" You take the rubber suddenly out of his hand and push him with your other hand softly back. "I should return the favor, shouldn't I?" You ask chuckling softly. Osomatsu moans softly when your hand touch his member. Osomatsu sits down on his butt while you pull his pants down. The condom placed aside at first. You are surprised to see how big Osomatsu actually is, before you gulp and lean down.

You give a small test lick up his shaft, causing Osomatsu to groan from the feeling of your warmth, wet tongue. 'How did the woman do this in the video? ... Maybe like this?' You lick now over the tip from his dick before taking it in your mouth. Osomatsu moans and lays his hands down onto your head. Panting softly while his eyes get filled with lust.

You start to bob your head slowly up and down. Osomatsu gets frustrated, grabs your hair a bit and starts to thrust in your mouth. You gag slightly when he thrust all in, but get used to it fast. Osomatsu keeps going until you can feel his dick twitch inside your mouth. "Ah, I'm cumming." Osomatsu groans, but before he can release his cum you pull suddenly away. Causing Osomatsu to whine frustrated.

"If you cum in my mouth Oso ... where would be the fun~?" Osomatsu runs a shiver down his spine when he sees you slide the condom down his dick. When you pull your hands away, Osomatsu grabs your wrist and pins you down onto the bed. "Hehe ... you really know how to make me fuck you, y/n-chan~." Osomatsu licks his lips before he lins up to your entrance.

You let out a muffled moan when Osomatsu press his lips down onto yours and slips at the same time his dick inside your pussy. Small tears welling up in your eyes from the pain, but thanks to Osomatsu's stretching out the pain turns into pure pleasure. Osomatsu pulls away and let out a shaky breath. "So warm and tight~."

Osomatsu groans when you thrust your hips back and forth. "Oso, please~" You whimper desperately. Osomatsu let go of your wrist but grabs your hips for that now. He press them down into the mattress, in order for you not to thrust by yourself. "Please what~?" Osomatsu hums next to your ear with a smile. He licks your neck, earning a mewl from you.

"Please fuck me~" You whimper out. Osomatsu smirks and says: "If you beg so nicely, how can I say no?" "Ahh~!" You moan out when Osomatsu starts to give a hard thrust and pulls out, only to thrust the same back into you. You lay your arms around Osomatsu's neck and locking your legs around his hips. Osomatsu groans from the warm feeling around his dick and thrusting faster and harder with every time you moan out his name.

"Oso~ yes~! Right there please~!" When Osomatsu hit your g-spot he smirks in victory before pounding this spot non-stop. You moan loudly and get turned on even more by listing to the wet sounds from Osomatsu thrusting into your wet pussy.

"Ngh! Your clinching at my dick y/n-chan! Do you love my dick that much~?" Osomatsu purrs and starts to gnaw at your neck softly. You moan out a 'yes' what makes Osomatsu thrusting even harder into you.

"Oso! I'm cumming!" You moan out and pull him closer. "Ngh! Me too!" Osomatsu smash his lips onto yours, kissing you deeply. Both of you moaning out loudly and cumming at the same time. Osomatsu let his cum out in the condom while you cover his dick in your cum.

You two calm slowly down and Osomatsu pulls away, so you two can catch your breath. Osomatsu let his body fall down onto yours, kissing your neck and leaving hickeys here and there. You pull with your legs Osomatsu closer while grinding against his dick even more. Osomatsu groans/growls and leave a small bitemark on your shoulder.

~And then...~
You two took together a bath (without having sex) while the clothes Osomatsu bought are in the washing maschine. You two sweat really much and when Osomatsu pulled out and took the condom off, he teased you with drinking his cum. Let's say it ended up with both of your clothes having his cum on it.

You sit in Osomatsu's lap and rub his hair dry, while he hugs your around your waist. "Mmmm~ we should do this again y/n-chan~." Osomatsu hums dreamy while burring his face in your chest. You blush and say with a soft voice: "But the others need their turns too, Oso-chan." Osomatsu groans frustrated from hearing this. He knows you don't want the others to think you don't love them so much and he doesn't want them to feel this way either, but that he needs to wait now so long is frustrating his not-anymore-virgin.

Suddenly, someone knocks on your bedroom door. "Y/n, it's me. Can I come inside?" Your older sister (Sister/name) ask from the other side. "Ah, y-yeah." (S/n) enters the room and shut the door behind her. She looks at your position, but shrugs it off.

"You have luck that Kaa-san and Tou-san weren't here." (S/n) sighs and walks over to your snack bar. Yes, you have one shelves just full with snacks. "Why?" You ask confused, but still dry Osomatsu's hair gently. "Because even with listing to music with my headphones weren't blocking your moans out." "Ah!"

You fall down from Osomatsu's lap, much to his disappointment. "W-What?!" You ask shocked and stand quickly up, with a huge blush across your face. "Yup. But lucky you I'm a nice sister. That's why I'll take all your snacks and won't say a word to Kaa-san and Tou-san." (S/n) put all your snacks inside a plastic bag from a konibi. "A-All my snacks?! Nee-chan, that's a ration for a whole month!" You say panicked. "I know. That's why I'm taking them. Thanks for doing business with me, y/n." (S/n) ruffles your messy hair before leaving your bedroom.

Looks like you need to buy new snacks.
