"Why do you want to videotape us having sex again?" I asked wanting some clarification from my boyfriend of 1 year. Osomatsu looked at me with a smirk holding the small camcorder. "Why not? Besides aren't you curious about how it looks?" I blush and look at him bewildered. "Why would I want to see it. Hearing it is enough...Especially considering the noises from you." I mumble the last part and go back to writing but he heard what I said.

"Oi!...it's not my fault. you're the one who knows what makes me like that."

I glance back from my work to see him blushing softly. "Can't we try it?" He asks and I sigh, dragging a hand down my face. "Here or love hotel?" I ask and saw him perk up

I sigh as I stare up at the love hotel entrance before being pulled inside by my boyfriend. I pay for the room along with a few extra things. Osomatsu was excited as usual when we walk to our room. I should explain something right away. I'm a guy. His parents know about us but not his brothers. If they were to find out they probably be like

"I didn't know you were gay Osomatsu." Well he kind of is gay but kind of not because he classifies as pansexual. To avoid confusion he just keeps his sexuality silent.

I took out the key and open the door. I let Osomatsu set up the camera while I look around. This room was a little nicer than the last one. I look at Osomatsu to see he had set up the camera on the side of the bed rather than in front of the bed. When he finished I sat down at the end of the bed. "Ready Osomatsu?" I ask and he nods turning the camera on before walking over to me.

He smiled and bent over to kiss me. I smile into the kiss and kiss him back deeply. He sat on my lap as I lick his lower lip. He pulls back for a breath before kissing back, opening his mouth for me. I smirk and pushed my tongue into his mouth. I scoot us back to the middle of the bed before I pull away to slide his hoodie off followed by my shirt. I run my hands along his stomach and squeeze his chubby sides causing him to blush.

"Oi stop that." I smile and lean in to kiss his chest. "Why? I think your chubby body is cute~" I coo before kissing his neck. I bite that soft spot that makes him melt and he moans softly. I smile and push his bottoms off, he had to sit up and move his legs a little so I could pull them off, I threw them to the floor and look down at his already throbbing erection.

I reach behind me to grab a squeeze bottle of lubricant and pop the cap open. I squeeze some onto my fingers, coating three of my fingers with it. I place the bottle to the side and went to kiss that spot on his neck again. As I kiss and lick the spot I reach my hand behind him and push a finger into him. He flinched and bit his lip. I smile as pump my finger in and out of him.

When I got all three fingers inside of him he whined. I hum "you want something Osomatsu?" I ask and he moans as I curled my fingers. "Y-Your f-fingers..m-more..I want Ha!~ I n-need more!~ please~" I smirk and kiss his neck softly before pulling back. I removed my fingers and he gave a whine. I flipped us over and pin him to the bed. I kissed my way down his throbbing dick.

I kiss the tip and it twitched slightly. I smile before taking him into my mouth and pushing my mouth down to the hilt. He threw his head back with a moan and lays his hands on my head. I hear his breath hitch as I bob my head letting my tongue swirl around his dick. "Oh~ t-that f-feels good~ Ah~" his voice wavered.

I bobbed my head faster and he bucked his hips "y-y/n~ I-I'm a-about to c-cum~" I hum causing him to gasp from the vibration. I smirk and speed up my pace while hollowing my cheeks. His grip on my head tightens as he forced my head down. "Hnn!~ y/n! I'm Cumming!~" he moans out as he came into my mouth. I hum and pull away.

I held his face and had him face me. He looked at me with lidded eyes as I open my mouth to reveal some of his cum still on my tongue. I open his mouth and kiss him, pushing my tongue into his mouth, spreading the rest onto his own tongue. He hums and wraps his arms around my neck before kissing me back. I pull away and got off the bed to grab something. I had went over to pick up a 8 inch vibrating dildo, Osomatsu had requested it.

I walk over to the bed and show it to him. He blushed lightly but nods. I smile and pick up the squeeze bottle. After applying lubricant to our little sex toy I nudged his asshole with the tip of it before pushing it in. I pushed it halfway before pausing to let him adjust and remove my own bottoms, my erection was threatening to break through my underwear. I saw the there was a slight wet spot and smirk. I drop the clothing to the floor and go back to Osomatsu.

Osomatsu was squirming around and rolling his hips. "Y-Y/n~ P-Push it deeper~" I smile and pushed the toy further until it couldn't go any deeper. He shudders and hums "oh~ that f-feels so good~" I smile "Hey Osomatsu~ did you know about there's something special about this toy?~" I purr and he shook his head.

"What is i-Oh!~"

He cut himself off as he moaned loudly. I had turned on the vibration to low. He moans and bucks his hips "y-y/n~ t-that feels soo g-good~" I hum and set the vibrations to medium "Let's set it higher than" I say and he keens. He threw his head back and his tongue lolled out. "NYAH!~ I'm about to cum!" He moaned but I reach out to grip the base of his dick.

His body jolts and he whines "why?~ I'm so cl-" "uh uh, I want you to hold back. At least for this level." Before he could even ask I set the vibration to the highest level. He wails out in response and moans incoherently. After a few minutes of him moaning and writhing under to hold he couldn't take it.

"Y-Y/n!~ P-Please!~ I c-can't h-hold it!~ P-Please l-let me c-cum!~" I smile and lean over to kiss him while letting go of his dick. He moaned loudly into my mouth and arched his back. I felt his hot cum land on my chest and a little on my stomach. I sat up and he was twitching under me with a shaky smile, tongue lolled out of his mouth that was dripping with drool.

Then I realized the vibrations were still on so I turn it off, not wanting to overstimulate him, and gently pull it out from him. The small pop that sounded once I pulled it out was almost..satisfying. I settled myself between Osomatsu's legs. "You ready Osomatsu?" I ask and he nods "h-hurry~" I bite my lip he is so hot right now I thought as I lined my dick up with his asshole.

I held onto his hips as I push in all at once. He moaned and rolled his hips against mine. I started thrusting slow at first but within minutes he was begging for more. "Y/n~ F-Faster! f-fuck me h-harder!~" I smile and pull out to the tip before plunging back into him. "OH YES!~ Like that!~ fuck me just like that!~" he screams out and I just continue to pound in and out of him.

After about a minute of this I pull out and had him flip over onto his hands and knees. I place my hands on his hips and plunged back into him. He gave a choked gasp before moaning. "Oh~ I c-can f-feel you so d-deep inside me~" I bite my lip and thrust roughly. "Ah!~ K-Keep going!~" He cries out before I lay my body on his while thrusting harder.

He lays his forehead onto his forearms, moaning into the bedsheets. Though that didn't muffle the scream he let out once I hit his prostate. He threw his head back as he screams out and I felt him tighten around my dick. I let out a moan and straighten up to thrust harder to hit that spot.

"Ah!~ Y-Y/n I'm a-about t-to cum!~" He moaned out loudly and with a broken voice as I hit that sweet spot. Then he clenched down hard on my dick with a loud moan. "HYYAH!~ I'm cumming!~" he moans and I grip his hips. I panted softly as I gave a few more shallow thrusts before I felt my dick twitch.

"Oh!~ Osomatsu~ I'm cumming!~"

I moan as I came deep inside him while he shudders with an airy sigh. We were both panting and I rub his hips as I pull out. He whimpers softly when I pull out fully. We both collapsed but I fell on top of him. I smile softly and kiss his cheek. He smiled shakily while reaching up a hand to hold mine.

"Happy now?" I ask and he nods "very happy. Thank you." I smile and kiss him softly. "Should we stop the recording?" He shrugs "go ahead. We're the only ones who'll see it." He says and I nod "good point...I'll go turn it off now." I say getting up and shutting the camera off.

I went back to the bed and pull the covers over the both of us. He snuggled up to me and I smile stroking his hair back. "If people knew about us. Do you think they'd be surprised that you were the submissive one?" I ask and he chuckled "hmm? I think...most of my brothers would be..maybe not. I don't know." I smile and roll my eyes slightly. I hug him close to me. "I love you Osomatsu" He laughs softly and hugs me back softly kissing my cheek.

"I love you too y/n"

Extra (oh boy)

Osomatsu and I were returning from another date. We entered his house and it was mostly quiet. Though we saw his brothers shoes but then I heard sound from the living room. Very recognizable sounds and voices. Then I heard "Ah!~ K-Keep going!~"

My blood ran cold and I turn to look at Osomatsu. He had a face that was calm but you could tell he was horrified. He stormed up to the living room door and threw it open while yelling "What do you think you're doing?!" I heard his brothers scream in shock and a few apologies. I came up to the door and my gaze went to the TV. That had been playing mine and Osomatsu's video. Then my gaze went to the brothers.

They all looked embarrassed, confused, and slightly surprised. I walk up to the TV and stop the video from playing and turn it off. Both Osomatsu and I glare at the brothers. Though I sigh and pinch the bridge of my nose. "Osomatsu. Where exactly did you hid that camera?" I ask and he sighs "I hid it in a place I didn't think they would look. Guess I was wrong." I look up at them again and Karamatsu stood up.

"Um..I w-was the one who found it."

Everyone turned to look at him. "I didn't know whose it was so I thought if I played what was on it I could find out and then leave it be...but when I played it...I wanted to stop..they were the curious ones. S-Sorry." I hum and the others look embarrassed.

"We were only curious because we didn't think Osomatsu-niisan was dating anyone." Todomatsu says "much less another guy." Ichimatsu adds "so..we ended up watching it..Sorry Osomatsu-niisan and y/n-kun." Jyushimatsu says.

"It was...shocking to say the least..we didn't think you liked guys." Choromatsu says gesturing to Osomatsu. He hums and scratched his head "yeah~ I don't really talk about my sexuality do I? Hmm." Osomatsu says and I laugh at his almost laidback attitude. "Welp! I guess I'll just be honest now heh!" He smiled that iconic smile of his.

"your big brother is pansexual." He says pointing to himself with a small wink. I smile and saw a few of his brothers looked confused. "Eh? What's pansexual?" Jyushimatsu asks and I raise a hand "I'll explain it. For people who are pans, they don't have their choices limited to gender. They date for personality rather than the gender of someone."

"Basically, I don't give a shit what gender someone may be. I go after how they are rather than who they are." I laugh as his brothers gained deadpanned expressions.

"Heh. You sure know how to be blunt." Karamatsu says snapping of it with a laugh. The others follow with their own laughs while Osomatsu smiles with a small roll of his eyes. I hug Osomatsu and he hugs me back. "At least we don't have to secretive around them anymore." I say and he nods

"Oh hey, Osomatsu." Karamatsu spoke and Osomatsu looked up with a hum. "How'd you end up being a bottom?" He asked and I felt Osomatsu tense up before glaring at Karamatsu. "Okay this is where I'll kill you." Karamatsu just gave a cheeky smile and runs out of the room. Osomatsu kissed me softly before chasing after him. I smile and thought to myself


I love this crazy family.
