Ok I have no excuses for this one but #krtsk #kurotsukki nsfw

CW TW for cnc / consensual non-consent and somnophilia. Everything has been heavily discussed, safe words in play, but that’s mainly off screen and if this isn’t for you, please click away!

It starts simple enough, in an exact replica of a situation Kei himself had suggested. He knew he was prone to fall asleep on the couch, middle of a movie, head in tetsurou’s lap, and not a care in the world. All it took was a comment from Kei about how as long as tetsurou was

Careful, Kei would probably stay asleep as tetsurou shimmied his pants down enough he could slide into Kei’s waiting mouth, to plant the seed in his head. Their sex life was active, and god, Kei was like his perfect match. He knew every filthy thought that fluttered through his

Boyfriends mind, because it was mirrored in his own.

There had already been a few almosts but tetsurou hadn’t taken Kei up on his offer. Until tonight.

Like clockwork, just as the movie they had put on was hitting its midpoint, Kei gave up any pretense of him watching the

Movie to roll inwards, sleepy face dangerously close to tetsurou’s crotch. The air felt thick with tension, tension that he was sure Kei had to notice, from the way tetsurou’s gaze continuously dropped to Kei’s mouth over the course of the evening. Though, his sleeping form did

Little to show it.

He really was beautiful, tetsurou thought to himself, gently brushing his fingers along Kei’s cheekbones, his jawline, pressing a thumb gently to his slightly parted lips. He had to stifle a groan as even in sleep, Kei’s lips parted for tetsurou, eager to

Please. He was glad he had forgone his normal choice of ratty sweats for movie time, opting to remain just in a pair of boxer shorts. A pair of boxer shorts that were getting increasingly tighter as he grew.

He withdrew his hand from Kei’s face, moving to carefully pull his

Growing dick out of the front of his boxers. He cupped the back of Kei’s head so he could shift him closer, close enough that tetsurou’s dick could rest on Kei’s face. He started slowly, savoring the relaxed look on his boyfriends face compared to the flushed red head of his

Cock, leaving a sheen of precum wherever he touched. He used the hand cupping Kei’s head to tilt it and used his other hand to angle the tip of his dick past Kei’s pliant lips. He hissed as Kei immediately started suckling, tongue gently curling around him. Fearing he had woken

Kei up, he paused, but the deep, steady breathes coming from his boyfriend said otherwise. Tetsurou felt his dick jump, knowing that even in sleep his pretty perfect slut of a boyfriend knew what his mouth was meant for. Kei being asleep does hinder tetsurou’s moves though. He

Doesn’t want to wake the blonde up by accidentally choking him, so he sticks to shallow thrusts and just reveling in the eroticism of sliding his spit covered cock along Kei’s face. Kei starts to stir though, so tetsurou pulls back slightly, wanting to see Kei’s eyes as they

Refocus and he realizes what’s happening.

‘Tetsu?’ He hears Kei ask, mumbling around the head of tetsurou’s cock.

‘Yeah, baby?’ He pulls out completely, switching back to smearing the mix of spit and precum on Kei’s lips.

‘What are you doing?’ Kei asks, eyes blinking open

Slowly, eyebrows furrowing as he weakly attempts to push his head back against tetsurou’s hand. It’s not a safeword, so tetsurou slides his dick back into Kei’s mouth, ignoring his sounds of protest.

‘Shh, don’t worry about it baby. Just keep sucking, yeah just like you were

In your sleep.’ He thrusts a bit more harshly than before, knowing Kei was awake now. He pauses though, pulling out and looking Kei in the eyes. ‘Color?’

‘Green,’ Kei replies, before slipping right back into it. ‘Tetsu, wait. Stop, why are you-‘

The rest of his sentence is

Cut off as tetsurou slips his cock back in, hand holding him in place firm enough that Kei’s weak attempts to pull back are stopped. He keeps his pace steady, gagging Kei on his cock, only pulling back to listen to Kei’s cries of ‘tetsu why, tetsu no.’ They spur him on, but what

Pushes him over the edge is when Kei’s eyes which were watering from the onslaught of tetsurou’s dick sliding into the back of Kei’s throat, finally well up enough that big, fat tears slip down his face, mixing with with mess tetsurou already made. He groans, thinking to himself

About how if there is a higher power, he is going to hell. At least his minx of a boyfriend will be with him. Deciding he wants to hear Kei’s voice as he cums, he yanks Kei’s head back with one hand and uses the mess of saliva and his other hand to stroke himself fast and hard.

‘Shit, baby your mouth was made for me yeah? Open up, c’mon.’

Kei manages to gasp out a no, but makes no moves to fight tetsurou as the hand on the back of Kei’s head moves to his jaw, not even squeezing for half a second before Kei pops his mouth open, tongue darting out, his

Eagerness to swallow tetsurou’s cum beating his willingness to fake protest. ‘Fuck,’ tetsurou thinks as he hits his climax, streaking his cum along Kei’s face and awaiting tongue, ‘I love this man.’

As soon clarity rings back through tetsurou’s brain, he drops his hand,

Attempting to check in on Kei. His plans are forgotten though, when the second their eyes meet Kei is hauling himself up to smash their mouths together.

‘If you don’t touch me now, I’ll kill you,’ Kei gasps, grinding his hips down to press his own hard length against tetsurou.

‘Fuck, ok, I’ve got you.’ He slips a hand into Kei’s pants, barely wrapping his fingers around Kei’s leaking cock, before his boyfriend is once again sobbing, burying his face into tetsurou’s neck as he spills into tetsurou’s hand. Tetsurou works him through it, slowly rubbing

Circles on Kei’s back as he comes down. Kei finally turns his head, making eye contact with tetsurou with a contented hum.

‘Hi, love.’ Tetsurou presses a kiss to the corner of his mouth.

‘Eugh, messy. Bath?’ Is his reply. Tetsurou chuckles, before standing and carrying Kei to

Their bathroom. He starts the water, dropping in Kei’s favorite bath scents as it warms up. They help each other undress before climbing in. Once they’re settled, and have been soaking for a few minutes, tetsurou finally checks in.

‘Was that okay?’

‘Mm, more than.’

‘Anything

You didn’t like, or something you want more of?’

Kei hums again as he tries to think of an answer. ‘Ask me again in the morning, but I don’t think so.’

Tetsurou agrees, and then asks Kei if he wants to actually try and watch the movie or just head to bed. The glare he gets

Is enough to send him into a full cackle, and they head to bed.

It takes a few more weeks for them to dabble in this realm of play again. That’s not to say they don’t fool around, no, they go from sappy romantic love making to some of the dirtiest sex tetsurou has ever had in

The blink of an eye. And it’s also not because of Kei’s unwillingness, tetsurou had come home late once or twice to see their pre planned signal that Kei would be willing to be woken up mid-scene, but tonight was the first night that tetsurou was also in the mood.

Today was a

Long day at work, and nothing cures his stress and starts his weekend better than fucking his boyfriend. He can feel his dick twitch in interest as he sees the specific candle laid out, lid off but unlit, sitting on the nightstand instead of the dresser where they normally light

Their candles. Shucking off his pants and shirt, tetsurou pulls back the covers and crawls into bed next to Kei. His one hand slowly traces up Kei’s legs as his other one strokes himself to full size. Getting Kei’s shorts off is a process but the reward of spreading Kei’s cheeks

To see his hole already glistening and ready for him is worth it. He still grabs the lube, warming it up before sliding in one of his fingers. He can tell Kei must have fucked himself open just before laying down, because the second and third finger slide in with little

Resistance as well. Tetsurou has been able to hold back from making any sounds until he bottoms out inside a somehow still sleeping Kei. He curses, pausing for a moment to take in the scorching hot temperature of Kei’s body from being under the comforter, and how loose and pliant

He is beneath him. His first few thrusts are slow, careful, more like grinds, as he savors the thrill of being the only one in the world who’s seen Kei like this, at being trusted so much Kei is willing to let him use his body however and almost whenever he wants. It doesn’t take

Long for tetsurou’s selfish side to take over though. Deciding he’s had enough of pretty, docile, unaware Kei, he ramps up the speed of his thrusts. He can almost imagine the shift from unawareness, to confusion, to tears, and it spurs him on.

His imagination rings true and as

Kei wakes up, his sleepy moans as his body submits to the pleasure, turn into Kei slowly blinking awake, breath catching, whimpering in a mix of confusion and fright that has tetsurou’s insides twisting in pleasure.

‘Tet-tetsu?’ Kei stutters out, wide eyes trying to peer over

His shoulder.

‘Yeah baby. Recognize me from just the feeling of my cock?’ He uses his hand to press firmly on Kei’s shoulder blades, holding him back down as he stated to try and rise.

‘I don’t-‘ Kei starts, cutting off a shiver races through him. ‘I don’t know why you’re

Doing this to me.’

‘You will, soon enough.’ Tetsurou leans down to press a tender kiss to the shell of Kei’s ear, asking him his color once again.

‘So fucking green tetsu,’ Kei whines.

‘Love ya,’ he nudges Kei’s ear with his nose before pulling his head back and continuing

His thrusts.

‘I won’t,’ Kei shakes his head, disagreeing with tetsurou’s earlier statement. ‘Please, please stop. I don’t want this.’

‘Liar,’ tetsurou moves the hand pressing on Kei’s back up to turn his head, pressing his face into the pillow as he speeds up. ‘You say you

Don’t want it but your slutty hole is practically sucking me in. Admit it, you love being fucked by me.’ He yanks Kei’s head back so he can reply.

‘No,’ he sobs. ‘M not a slut.’

‘Yes you are. You’re mine. My slut, say it.’

‘Stop,’ Kei is crying again, but he’s also unable

To stop his hips from trying to bounce back to meet tetsurou’s brutal pace.

Tetsurou can feel himself teetering closer and closer to the edge, slowly losing the ability to say anything but his boyfriends name. He manages to growl out one more ‘say it.’

‘I’m yours, your

Slut,’ Kei finally sobs, spilling between his body and the sheets. By the time he’s coming back down from his climax, tetsurou’s pace is wavering. Kei smirks to himself before putting the icing on the cake. ‘Please tetsu, please don’t cum in me.’

Tetsurou lets out a punched

Out groan as his hips still, buried as deep inside Kei as possible, forehead pressed against Kei’s back as he does just that. They bask in their afterglow for a few more minutes, until Kei complains about laying in the wet spot.

‘Bossy,’ tetsurou groans.

‘You like it. Now,

Let’s start a bath, but you can’t join me til you change the sheets.’

Tetsurou whines, but he still carries a protesting Kei to the bathroom and dutifully changes the sheets before slipping in in front of Kei. He rests his back against Kei’s chest, and hums as Kei presses

Sloppy kisses to his shoulders.

‘Feel better?’ Kei teases.

‘So much. I’m ready for notes, any glaring issues or requests for next time?’ Tetsurou asks as he lets Kei wash his hair, long fingers gently scrubbing his scalp.

‘Manhandle me more next time, wuss.’

‘Keiii.’

‘You know, if you’re still feeling stressed, I could always fuck the rest of it out of you? Right here, if you’re up for it?’ Kei suggests.

‘Mmm. Give me a back rub first and then deal.’ They seal the deal with a kiss, which leads to much more, and only after Kei has taken his

Time bending tetsurou over the lip of the tub as he fucks him, do they finally head to bed. Kei turns off both of their alarms, declaring tomorrow a sleep in Saturday, and they drift off in each other’s arms.

End.
