I was at my boyfriend's place and was currently under the Kotatsu table. I was enjoying the warm while I could. Karamatsu was sitting opposite of me with his legs under the under blanket the lines the table. I hum from the warmth and lay my head on my folded arms. I love winter but I hated the cold. I hum as I felt something nudge my ass. I glance back at Karamatsu to see him smiling.

I gave him a look and he hums "What is it my dear?" He asks and I hum "you were nudging my ass with your foot." I say and he chuckles before nudging my ass again. "We gonna have a problem!" I shout playfully and he laughs. I laugh softly and hum as he went under the table. He lays on me and pokes his head out to kiss my cheek. "You enjoying the warmth?" He asks and I nod with a content hum. "Hey so when will your brothers come back?" I ask and he hums

"Um I don't know. Maybe a hour if they go out drinking after the bathhouse." He says and I hum. He hums and glances at me "that is a pretty decent amount of time." He says and kisses my neck. I hum and push on his face "oh come on. Don't do that." I say and he held my hand. "But if you want to feel warmth, why not use our own body heat?" He asks with sultry tone as he kisses my hand. I blush and glance away.

He hums and kisses my neck "What do you say y/n? You up for it?" He asks and I moan softly as he kisses my sweet spot. "y-yes~" he hums and turns my head to kiss me deeply. I moan softly as he pushes his tongue into my mouth. He hums and roams his under my shirt. I squeak softly as he squeezes my sides and he chuckles.

"Still have sensitive sides, sweetie?" He asks before rubbing my sides and I hum with a nod. He hums and kisses my neck as he moves to remove my bra. When it was off we just push it under the table. I moan softly as he squeezes my breasts. "You are so cute" He says before kissing me softly. I hum softly as his thumbs roll over my nipples.

I hum and pull away as he pulls my pants off. "Spread your legs dear." He says softly into my ear and I shudder before spreading my legs. He hums and I blush as I felt his hard on press against me. "There we go~" he purrs and kisses my neck as he grinds up against me.

I moan softly and grind back against him. He chuckles and holds my hips down. I whine but moan softly as he bucks his hips. I hum softly and lay my hand on his free hand. "Karamatsu~" I coo and he hums "yes, what is it?" He asks and I glance back "can we just do it? I know you like being gentle but..I think I can handle it. So could you just um.." I blush at his almost blank stare and glance away "never mind"

He hums and lifts his hips, letting go of my hips, before I hear him undo his belt. I felt my skin tingling as his hand went to pull my underwear off. I bite my lip with a blush when I feel his dick nudge my pussy. "Is this what you want?~" he purrs and I shudder "yes~ I want it~" I say with a whine and he hums as he moves his hand up to hold my waist. I moan softly as the tip pushes in "Seriously~ Just put it in~" I glance back and smile "I'll be okay~"

He smiles and kisses me deeply. I moan out into his mouth when he thrusts in to the hilt. I grip my sweater and pull away from him with a hum of bliss. Karamatsu hums softly and kisses my neck. I lay my head on my folded arms and moan as he starts to thrust. It wasn't slow but it wasn't really fast either. "Oh~ Karamatsu~" I moan and he hums "feel good sweetheart?" I nod with a gasp as he grazes my g-spot.

I lean my head back with a whine and he smiles "oh~ did I find your sweet spot?~" he coos before hitting it again. I moan and hid my face into my arms. He hums and kisses my cheek as he thrusts a little harder. I moan and bite my lip as I felt my orgasm approach. Karamatsu hums and nuzzles his face into my neck.

Both of us jump when the door to the living room opens. How did we not hear the front door? Were we that distracted? Well we glance up and saw Osomatsu. "Oh hey, you're still here y/n?" He asks and I hum "um yeah..sorry." I say nervously and he hums "that's fine." He says before he walks into the room. Keep in mind he could have sat anywhere.

But noo. He decided sit down. at the Kotatsu table.

Thank goodness he was sitting cross legged but still.

Unfortunately when he first sat down Karamatsu flinched a bit which made me gasp softly before I cover my mouth. "You okay y/n?" Osomatsu asks looking at from his comic. I gave a thumbs up and a nod. I was too afraid to speak because my voice would fail me. Thankfully he shrugs it off. Karamatsu leans up to my ear "Sorry. I didn't mean to flinch." He says and I huff before burying my face into my arms. "What's wrong?" He asks and I blush heavily. "I..I need to..I need to cum." I whisper trying not to whine.

"...oh..well I can pull out an-" I shook my head "no..the slightest movement and I'll...my voice.." I trail off and he hums in thought. "What are you guys whispering about?" Osomatsu asks and we glance at each other before we look over at him. "Nothing." We both say in sync and he hums "Okayy then."

Karamatsu sighs and whispers "we can't just stay like this..even I'm starting to feel..just let me pull out and we can finish this upstairs." I sigh and bury my face into my arms with a hum. He hums and, carefully, pulls out. As much as I tried I couldn't hold back the small whine and my face turns red. "Y/n your face is red." Osomatsu points out and I hum "yeah? Really?" I ask as Karamatsu pulls my bottoms back up along with his and Osomatsu nods.

"It's probably from the heat of the Kotatsu table and her sweater." Karamatsu says and I nod before crawling out from under the table. "I'm kind of tired actually." I say as I stood up "Oh? So you heading home?" Osomatsu asks and Karamatsu hums "not in the cold she's not." He says before quickly getting out from under the table and stood up. "I can step up futon and you can sleep over." He says and I nod before we quickly left the room.

We rush into the bedroom and close the door. He was quick to pin me to the wall, kissing me deeply. I moan into his mouth and reach my hands down to hastily undo his belt, pushing his pants off while he did the same. He lifts me up and I wrap my legs around his waist. He pulls away and I smile at the sultry look in his eyes before he plunges back into me. I moan and grip onto his back as he thrusts roughly.

"Oh~ were you t-that effected by Ah~" I was cut off by a moan as he hits my g-spot. "Yes~ you don't know how frustrating it was for me to not be able to move." I shudder at his tone of voice. It gave me chills. "Feeling your tight pussy around dick is enough to drive me crazy. Enough to make me needy~" he purrs and heat floods my body as my body trembles under this tone of his. "H-How n-needy?~" I ask with a moan as he hits my g-spot.

"Heh. You fill me with the need to fuck you senseless~"

I moan and lean my head back as I came. I whine and bite my lip as he thrusts harder. I moan and clutch onto his back. "K-Karamatsu m-my v-voice~ I'm g-gonna g-get loud~" I whine and he kisses my neck as he grips my hips "At this point, I don't fucking care. Let him hear. If they have any problems they have me to talk to. So I have one question~" he leans up to my ear and lightly blew onto it.

"Who's your daddy?~"

I blush and bite my lip. Sometimes I forget he has that kink. I moan as his thrusts didn't cease. "Oh!~ you are~" I moan and he licks the shell of my ear "then let me hear you say it~" he purrs and I moan softly "D-Daddy~" I moan and he nips at my ear "let me hear that dirty voice~" I whine softly and gnaw at his neck

"Oh Daddy!~ Ah!~ I can feel you so deep!~ I can feel down to my core!~" I moan out and he moans as well. "I can feel you tightening up y/n~" I moan and bite at his neck. "Oh~ I'm so close~ please say my name love~" I smile shakily and moan out "Oh Karamatsu!~ Oh~ cum for me baby~" I moan into his ear and I felt his whole body shake before he gave a final deep thrust with a loud drawn out moan.

I moan and shudder with a smile as he came inside of me. He pulls out and gently sets my legs down. My legs immediately give out and I fell onto Karamatsu. "Oh sorry. I didn't mean t-" I cut him off with a kiss and smile fondly "don't apologize~ I love that side of you~" I say and he hums with a blush before having me sit down as he got the futon set up. He places me in the futon after redressing me and I drift off to sleep with a smile.

I don't know what switch I flipped but I'm glad I did.

-Karamatsu's POV-

I watch as y/n went to sleep and pull my bottoms back on. Then I realized something. "Oh shit. Her bra is still under the table." I say but sigh and head downstairs. I open the door to the living room and Osomatsu glances at me. He just stares at his comic as I walk over to the table and lift the blanket. "Uh So Karamatsu?" Osomatsu finally speaks up and I hum when I spot the bra.

"Are you okay?" He asks as I quickly shove the bra into my hoodie pocket. "Yeah. Why?" I ask him before standing up and he hums "you aren't like mad that I came home early, right?" He asks and I hum "No. It was just an inconvenience. So I'm not mad." I say and he seemed relieved. "Serious talk though. Sorry about-" I held my hand up and smile "it's fine. Now if you had actually interfered to where we couldn't continue" I tilt my head with a smile

"I would kick your ass."

His laughs nervously "right..I'll keep that in mind." I smile and laugh "I'm only joking." I say and head to the door "but seriously do not interrupt us. Okay? Good." I say before heading upstairs with a smile as I heard Osomatsu say

"Jeez you can be scary at times." I just respond with a simple "I know." before heading upstairs to join y/n in the futon.
