Work Text:

Why were you friends with these brothers? Your friendship was fucked up with them. You met them at the cat cafe, you worked at and surprised that there were six. You have seen twins before but six?? You felt bad for the mum!

The second oldest, Karamatsu, who was wearing the shades and all, tried to flirt with you until his brothers attacked him. You thought it was funny since he sucked at flirting. Well, mostly that it was suuuper cheesy. After they finished, they said they didn’t have the money, which pissed you off. Why go to a cafe if you have nothing!?

Your boss was mad and you asked if they help clean up after it closes. He agreed and the six cleaned up....Well, you did the most since they kept fucking shit up. They kept coming back, sometimes they paid and didn’t pay for their food and drinks. They later invited you for a drink, the six looking embarrassed but you agreed anyway.

You then realized they were ass holes. Ass holes with soft hearts...but still...Ass holes. They were also virgin dorks, which you didn’t mind. You only slept with one guy but you totally regret it, since that was a stupid college thing to do.

The six at times flirted with you, got nervous or just hung out with you, getting into all kind of trouble. You didn’t mind resting in their room and reading your book in silence, while they did the same or talked.

They were ass holes but....They were your ass holes.

~

You sipped your drink as you were drawing in your book, hearing the tv in the background. Today was your day off and wanted to relax, until you heard your phone. “Hm?” You picked your phone. “Hello? _____, here~” You said.

“Ah! _-_____-San!” A cheerful voice said on the other end. It sounded like Osomatsu. “Sorry to bother you! Urm...Are you busy? I want you to come round..”

You blinked. “No, I’m off today, so--”

“Great! Come to my house in an hour, bye!” He then hung up.

“....Dick..” You grumbled and placed your phone down. You didn’t even have time to speak, what an ass hole. “What did he want..?” You said to yourself.

~

You walked to the sextuplets house, wearing your usual clothes. You were still wondering on what he wanted. Was he going to prank you or something? You knocked on the door but saw it was already unlocked. You closed the door behind and looked round. “Osomatsu? You here?”

You heard footsteps coming down and saw the red hoodie, including that bright smile. “Ah! _____! You came~” He went over and took your wrist, walking you upstairs. “The others are out at the moment, so it’s just you and I!”

You raised a brow. “O..kay?” You went to his room, seeing it was clean but with a few comics next to the couch. “What do you want anyway, Oso?” You crossed your arms. “You hung up on me before I can ask..”

Osomatsu wasn’t looking at you but saw him sweating madly. “U-urm..” He poked his fingers together. “Man..I didn’t plan this through..” He muttered to himself. He took a deep breath and turned to you, having a serious look in his eyes. “...Will you teach me how to pleasure a girl!?” He shouted and blushed, bowing his head.

..........

You walked to his door. “W-Wait!! You can’t leave!” He shouted, reaching out to you. “I need help!”

“Osomatsu, I can’t teach you!” You turned to him, a light blush across your face. “Don’t you know what you’re asking of me?? You pretty much want to kiss me and--Just no!”

He want on his knees in front of you, tears streaming down. “Pleeeeeeease!!” He hugged your ankle, trying to kick him off. “Don’t you know how embarrassing it is to ask for help!? I’m the oldest brother, I need to learn!”

“Your brothers were born minuets after you! You’re all the same age!” You shouted, kicking him in the face. “There is no difference!”

“But they look up to me, _____-San!” He shouted, taking your hits. They didn’t look up to him, phtt-please!

He went silent and pulled away, looking at the floor. “..._____...Please. I’m begging you. I want to learn..I’m..Nervous round girls but you and...I want to learn how to make them happy..” You blinked at that. “I can’t talk to my brothers about this kind of stuff...They would just laugh at me..You never look down at me like other girls..You give me and my brothers a chance..Sure, we annoy you but...We care for you..” He raised his head, looking at you with a kind face. “Please...Teach me..”

You were silent. This was so out of character of him, saying that they were annoying and his brothers would laugh at him. You did feel bad for him but what if he was tricking you? He has done it before but...His eyes...You trusted him.

You sighed and shook your head. “Fuck sake...Fine..I’ll teach yo-”

“Wohoooo!” Osomatsu jumped up and cheered, excitement filled his body. You sighed and face palmed.

What did you get yourself into?

~

You sat across him, sitting on your legs with a rolled up news paper next to you for....Reasons. “Okay...What do you usually say to a girl?” You asked.

Osomatsu blinked at you, then looked at your chest and back to your face. “...Your tits are ni-Ow!” You slapped him with the news paper.

“You don’t say that! The girl would totally call the cops on you!” You sighed. “If you see her in a cafe, say hello and ask if she wants another drink. Sit across from her and tell your name, then do small talk with her. Does she live round here, got any siblings, her favourite food...You know, small talk..”

He blinked, rubbing his red cheek. “I don’t talk about me?”

You sighed. “I know you like to talk a lot, Osomatsu but nope. Girls like it when you’re interested in them and let them talk. Only talk if they ask you a question but don’t talk for a long time about it. You know, small talk, small talk..” You said, putting your hands together.

“Ahhh got it!” He thumbs up and smiled, glad he was paying attention. “When do we get to kissing?” He grinned.

“Not yet..” You blinked dull. You talked to him about small talk and body language, seeing he was slowly losing interest. Fine, to the next stage. You then sat next to him, seeing he was blushing. “Okay..Urm..” You lightly blushed. “Show me..How you kiss..” You muttered, a bit nervous yourself. You always thought what it would be like to kiss one of the Matsuo brothers.

His eyes sparkle and nods. “Okay!” He then mashed his face into yours, your teeth hitting together. Oh god, no.

You pulled away and shook your head. “No, no, no!” He blinked at you. “Oso...Sorry but...That was awful..Like-the worse kiss I have ever had..”

He looked hurt at that. “Really? I thought girls liked forceful kisses..” He muttered.

You sighed. “Some do...But you don’t just..Thrust your face into theirs. It is totally not sexy nor romantic..” You sighed. “Okay..Let me lead and you soon follow..”

You rubbed his cheek and leaned close, softly pecking his lips. He froze, his fingers lightly gripped his pants. You closed your eyes and sweetly kissed his, his lips not moving but slowly moved them against yours seconds later. He was a quick learner. His lips were pretty soft and tender against yours, slowly forgetting you were teaching him.

He pulled away and panted, his eyes sparkling. “Wow...Can we do that again? I think I can lead now..” You blushed but nod anyway. His fingers ran through your hair and kissed you again, humming softly. He closed his eyes and kissed you a bit deeper but this time, you didn’t pull away. You bit his lip and slipped your tongue in his mouth, making him lightly moan.

“Mmm..” You pulled away, seeing he looked eager. “Not too much tongue, Oso...And move it against mine..” You lightly smiled.

“Sorry..” He muttered against your lips and kissed you again. His tongue fights yours, his tongue not lying there like a dead fish now. He was good..Like..Really good.

You froze, feeling hand slip under your shirt and cupped your breast, while the other rubbed your thigh. “Mm..H-Hey...!” You slapped his hands away. “Don’t..Urm..” Fuck, you couldn’t think straight. “Don’t force yourself on her..”

Osomatsu blinked. “But..You were enjoying it..?” He muttered.

“We’re..We’re training you..This is not real..” You looked down. Why did you say that? Your heart was ramming against your chest, your face red. “..Anyway..Just placing a hand on her thigh is good enough..”

“Okay..” He muttered, looking a bit upset. He wanted this to be real. He wanted you. “Then..What next..?”

“Well..” You swallowed. “When you go into the bedroom, go slow with her...Unless she is horny as hell but also care for yourself..” He nods at that. “..N..Now...Take off your shirt..And I will take off mine..”

“O-Okay..!” He quickly tossed his shirt and tossed it aside. You looked at his body. he was slim, no muscle nor chub. You didn’t mind it but you Wished he had more hair though. He had a happy trail but still. You swallowed, taking off your shirt slowly. Osomatsu watched every second, his eyes widen at your body. You were...Fuck..

You blushed, your arms covering your stomach. “Heh..I know I’m not good looking as Totoko bu-”

“You’re beautiful..” He muttered. You froze, looking at him. He...called you beautiful? That was..touching and the most normal thing he has ever said to you. He looked at your face and blushed, looking to the side. “I-I mean..Urm..It’s okay..”

You rolled your eyes and leaned forward, kissing his cheek. “Thank you..” You whispered, making him freeze in place. You both looked at each other and smiled.

“..Oh! Urm-Now..This is tricky but..I want you to..Unhook my bra..” You said, looking at him.

“...Eh?” He blinked. He looked at you bra and blinked. “...Hmm...It looks hard to take off..” He muttered, staring at your chest.

It took a long time before he took off your bra but you were patient. His eyes widen as he saw your nipples, getting a nose bleed. Your nipples were already hard from the cold and...Other things. “..M-May I..?” He muttered.

“S..Sure..” You said. He cupped your breasts and groaned, pressing them together. “So good..Soft like..Pillows..” You snort at that and giggled.

“You..Can say tha-Ah-” You moaned, feeling his thumbs on your nipples. Osomatsu froze and looked at you. “U-Urm..Sorry..That took me by surprised..” You blushed. “It’s okay..It felt..nice..”

He nods and rubbed them again, pinching your nipples. You whimpered and closed your eyes, bucking your chest to him. Osomatsu drolled and grinned as he watched you, loving your moans. He was doing this to you and no one else was. He was the first of his brothers and that turned him on. Well-He was hard when you kissed each other but still!

He remembered seeing a scene in a porno and wanted to do it. He leaned forward and sucked your nipple, making gasp and cry. “O-Osomatsu-” you moaned, running your fingers through his hair. He continued to rub them as he pinched your nipple with his teeth.

“Mmm..Fuck, ______-san..Your sounds are so fucking hot..” He muttered and sucked the other, making you tug his hair. He’s feeling bolder and started to nibble your neck, sucking at the fresh skin and left marks on your body.

“O-Oso, stop--Don’t leave M-Marks on me..!” You whimpered, trying to push him away, but he pushed you onto the floor. He grinds against you, making you both moan. “O-Oso..Matsu..!” You whimpered.

“Please..Please teach me more..!” He begged, looking down at you. You blushed, feeling his hard cock rubbing against you. “Oh god..I might cum in my pants..” He mutterd and moaned.

“P-Please don’t..” You whispered to yourself. You pulled him away and slipped off your pants, seeing your underwear was damp. Shit...Oso did this to you. You never thought that one of the brothers would turn you on.

You took his hand lowered it between your legs. “Rub..Mm..here..” You muttered. Osomatsu nods and rubbed, making you moan.

“Holy shit, ______...You’re so fucking wet..Wet for me..Fuck..” He muttered and watched your face, rubbing your clit. You bucked your hips and moaned, your head going back. You blushed, hearing how wet you were which made him grin. “Such a horny girl..”

“S-Shut it..” You said and rubbed his cock over his pants, making him groan. “S-Stop..Take off my underwear..” You muttered.

He blushed, his ears going to the same colour. He grabbed your underwear and looked at you, seeing if you were sure. You gave him a nod, letting him slide them off. His eyes widen, finally seeing your pussy. Holy shit..He saw it lightly twitch and drip. It was like a weird creature but he didn’t say it out loud. “You’re so..Amazing..” He muttered. He looked at your underwear and sniffed them, making you blush. “Mmm..Smell so good..” He licked the damp area, groaning deeply. “Shit..”

You watched him, your legs rubbing together. It was kind of gross but...So fucking hot. “Osomatsu..” He looked at you and blinked. You nervously opened your legs, opening your lips with your fingers. “You..W-Want to touch..?”

“......” He nose bleed again but quickly wiped it off. You took his hand and leaded him.

“Mmm..Good..Then just..Slip a finger inside..” You muttered. He slowly slipped his middle finger inside, making you moan. He blushed, feeling your warm cream. He might cum right now! He then started to move his finger inside, curling it up. “Mmm..G-Good..Ah..You’re doing so well, O-Oso..” He smiled at you. He was proud of himself. “..Y..You can enter another..” He nods and slipped another finger inside, spreading your walls. “A-Ah-! Yes...O-Osomatsu..” You closed your eyes.

He groaned as he watched you, breathing deeply. You looked so hot. Shaking from his touch, moaning his name and bucking your hips. “Oh fuck...______-San..Please..can I taste you...I’m B-Begging you..” He groaned, drolling slightly. You looked up at him and nods, spreading your legs more. He lowered his head and licked your clit, making you shiver from his tongue.

“Ah-O-Oso..Osomatsu..!” You moaned, gripping his hair again and buried his face in your pussy, hearing him groan against you. He was fucking amazing. How did this geek became so bad and now, making your world spin.

You rested your back on the floor. “O-Oh god...Y-Yes..yes...! Ahh...M-More..Thrust your F-Fingers inside..Enter another..J-Just--please..!” You cried out, begging him to fuck you with his fingers and tongue.

“Of course..” He grinned and thrusted three fingers inside of you, licking your clit. You cried out and shot your head back, your hips off the floor.

“O-Osomatsu, Osomatsu, Osomatsu..!” You cried out his name, your thighs slightly pressed against his head as he faced fuck you. “Oso..! I-I’m..I’m...!”

“We’re hoooome!” Jyushimatsu shouted.

You both froze, your blood running cold. “...Shit..” You both pulled away and panicked, hearing foot steps. ‘Shit, shit, shit, shit!!”’ You screamed in your head.

“In here-” Osomatsu grabbed your clothes and opened the cupboard, tossing the clothes inside and grabbed you.

“Helloooo!” He shouted and burst through the door. “Huh?” He looked round, seeing no one was home. “Oh..No one is here~”

Ichimatsu walked in after him and blinked dull. “Huh..I thought Osomatsu was going to be home all day. Guess he lied..” He flopped on the couch, his legs crossed.

You and Osomatsu were in the cupboard, panting softly. That was so close. You looked through the gaps, seeing they were just talking about spots.

“Muscle muscle, hustle hustle!” He chanted, rolling on the floor.

Osomatsu looked at you, since he was behind you. He looked at your neck, back, then your ass. He saw you rub your thighs together, your juices going down your thighs. He drolled and groaned lightly. Oh fuck, you were hot. He couldn’t take it any more, his cock was getting cramped in his pants. He undid his belt and smirked. “Heh..”

You watched the other brothers until you gasped. “Huh...Did you hear that..?” Ichimatsu said, looking at the window.

“Haha, nope!” Jyusimatsu laughed.

You blushed and looked down. “O-Oso..” You whispered. his hands were on your hips, his cock rubbing between your thighs, his cock getting wet from your dipping cunt. “S-Stop..You’re brothers A-Are right there..”

“I..I can’t hold it in..” He whispered in your shoulder. “I need you..I need you now..” He lightly growled, thrusting himself inside. He placed a hand over your mouth as you cried out, making it muffle.

Your eyes widen and blushed, feeling his cock inside of you. Holy shit, holy fuck!! “Mmm-”

“______-san, ______-San...You feel..Amazing..Your pussy feels so good..” He groaned and twitched inside of you. He then started to thrust, his hand still covering your mouth as he gripped your waist.

You bit your lip, trying to hold back, going teary eyed. You watched the two brothers, your walls twitched with panic and excitement. Osomatsu groaning your name in your ear made your body go on fire.

“I-I’ve wanted this for so long..Ah..D-Do you have..hah..any idea..How many times I jerked off to you..?” He muttered, nibbling your neck. “T-Too fucking..M-Many...You’re mine..A-And only mine..I-I’m the fucking lucky one..” He muttered, slapping against you as he brought your hips back.

A few tears ran down as you moaned in his hand, listening to his words. You were flattered but still scared about this. If they hear one moan or anything, they will find you two. “Mmm...Mmn..!” Your eyes widen, seeing Ichimatsu looking at the cupboard, squinting slightly. Oh no, Oh no. Osomatsu, stop-Please!

He got up and was about to walk over, until he heard the phone. “Huh...I’ll get it..” He then walked out. His yellow brother laughed and got up, following him.

When the door shuts, that’s when you both cried. “O-Oso! You’re such A-An ass hole! What if W-We-ah! Got caught..!” You said, your hands on the cupboard door.

“But W-We didn’t get caught..” He smirked, thrusting hard and faster, panting deeply. “I-I bet you’re turned on about it..” He moaned. “I-It’s exciting..Thinking about getting caught..” He muttered, slapping your ass as cupped your breast.

You gasped and moaned, moving your hips back. “J-Just cum..Please..!” You begged. “O-Osomatsu!”

He groaned and smirked, droll going down his chin. He opened the small cupboard and pinned you on the floor, fucking you like there was no tomorrow. You gasped and cried out, looking up at him. He was looking at you like a wild animal, his eyes looking crazy, one of his pupils was a heart shape. How the fuck did he do that? “C-Cum for me, _____-San...I want to see you cum!” He cried out, his thrusts becoming sloppy.

You kept crying out his name, tears running down and droll down your chin. How could Osomatsu make you feel like you’re in heaven. This..This was fucking amazing! Yes! One of the Matsuon’s made you feel this way, the virgin dorks! “O-Osomatsu! Osomatsu! Osomatsu!!” Your hand started to rub your clit, making you cry out like a fucking slut.

“______-san..!” He moaned and kissed you, slipping his tongue inside. “Mmm..” He held your waist, slapping against you. “I’m C-Cumming inside..! I’m cumming!” He cried out.

“Osomatsu!!” You bucked up and cried, finally cumming all over his cock. He gave a few weak thrusts and came inside. You whimpered, feeling his hot cum inside of you. He rested on you and panted, closing his eyes. You both rested there and panted, swallowing in some air.

“Hah...Ah.._-______-San..” He looked at you and smiled. “You’re amazing..”

You weakly smile back. “That..W-Was..Fucking incredible..” You both jumped, hearing them coming upstairs again.

When they came in, Ichimatsu looked at the cupboard, seeing it was slightly open. “.....” He walked over and opened it, seeing it was empty. “Hm...My imagination then..”

~

“Driiink!” The boys drank down their beer and groaned, their faces red. “To _____-san!” Osomatsu cheered.

“Why does he keep bringing ______-san up?” Todomatsu asked and raised a brow as his drunk brother.

“I don’t know...He’s been saying her name non stop..” Choromatsu sighed.

As they walked home, Osomatsu brightened up, seeing you walking home. “_____-saaaan!!” He ran over and hugged you.

You gasped and blinked, looking at him. “Geez, Oso. You blood smell of beer..” You said, rubbing his head.

He pulled away, so you can see his red face. “I missed-hic-You! I want to learn W-With you again..!” He said, his brothers looking at him in confusion.

“...I don’t think that will happen, Osomatsu..” You said softly.

“Oh..” He blinked, look hurt but deep down, he understood.

“...I..I want to go on a date with you..”

“Eeeeeh!?” His brothers screeched

“A-A...Date?” His eyes widen.

“Yeah...I..” You blushed, holding his hand. “Want to be your girlfriend..” You said softly and smiled.

“EEEEEH!?” They brothers screeched again.

“G-Girlfriend..!?” He said but then smiled brightly. “Oh course!! Oh man, I’ve wanted to be with you for so long..!” He hugged you close, both of you kissing each other.

“EEEEEEHHH?!?!?!?!” His brothers fell on the floor.

You pulled away and smiled. “Mmm..Night, Osomatsu...I can’t wait for you to make my knees weak again..” You muttered and winked before leaving.

He waved you off and drunkly giggled, before turning to his brothers. “Gh!!” He jumped, all of them staring at him.

“..Pin him..” Choromatsu muttered, his brothers pinning him down. Osomatsu gasped and tried to get out of their grasp.

Karamatsu took off his shades and walked over, cracking his knuckles. “You have a looot to talk about, big bro..” He said darkly, growling.

“B-B-Bro’s, come on now...Bro’s? Bro’s! W-Wait! Ghaa! Not the nipples--GHAAA!!!”
