#krtsk #kurotsuki omegaverse nsfw role reversal I guess?

Tetsurou’s face was buried in their pillows, fingers twisted in their sheets as Kei moved behind him. He was vaguely aware of the tear tracks on his face, eyes spilling over when Kei was three fingers deep and making

Him beg for his cock. He had caved easily, pleas coming out syrupy sweet until Kei had laughed, curled his fingers in and demanded he do better. Then, then he had pleaded desperately, tears dripping down his face until Kei had deemed him worthy and slid inside of him with one

Smooth thrust. A particularly sharp snap of Kei’s hips had Tetsurou moaning, gasping for breath.

‘Look at you, my pretty alpha takes my cock so well. You like how I fuck you?’ Kei’s voice has a condescending lilt to it that has Tetsurou replying with a whine instead of words,

Arousal coursing through his veins.

They had been together long enough that exploring each other’s deepest desires was a given, both of them ensuring their partner felt safe in the bedroom expressing their needs, that even though his words were on the edge of degrading, Kei was

Giving Tetsurou exactly what he needed. Letting him ignore his alpha side, letting him get fucked within an inch of his life. They didn’t do this often, their inner instincts winning over more often than not, but it made it all the more thrilling when they did. It’s not like

Tetsurou was insecure in his presentation or anything, they had just always taken the social norms for their relationship and ignored them. He remembers when they first started dating, Kei had been Tsukki back then, and had been concerned that he wasn’t ‘omega-like’ enough for

Tetsurou with his height and his snark. It had taken time and reassurance for Kei to feel comfortable and confident that Tetsurou loved him exactly as he was, gender norms be damned.

They had continued to defy them as they aged. Kei staying on with semi-pro volleyball, growing

Muscles yet remaining lean. Tetsurou, choosing the corporate world, losing his once prized abs as his workout shifted from daily volleyball practice to a once a week gym session and extracurriculars in the bedroom. He wouldn’t call himself out of shape, but he knows he had a few

Extra pounds rounding out his thighs and his ass and slight pudge in place of the aforementioned abs.

He knew Kei still found him attractive, always taking note of when his boyfriends eyes lingered on his body, heat blazing in them. It was one of those looks, paired with Kei

Standing in their room dripping wet from the shower with a towel slung around his waist, muscles glistening, that had Tetsurou breaching the topic of Kei being the one fucking him and it had only evolved from there.

‘That wasn’t an answer, alpha. Do you like how your omega

Fucks you?’ Kei tries again, fingers digging into Tetsurou’s hips.

‘Yes, Kei, omega, please. I like how you fuck me.’ He manages to gasp out.

‘Good boy, that’s my sweet little alpha.’ Kei’s pace was punishing, Tetsurou was doing his best to bounce backwards to meet him. ‘You

Look so nice for me, presenting so perfectly.’

‘Oh fuck, Kei.’ The only thing stopping Tetsurou from reaching down to palm his throbbing cock was years of practice.

‘Hm? Does my big bad alpha like being compared to an omega slut?’ Kei tightens his grip with one hand, using the

Other to run a soothing touch up Tetsurou’s back as he shivers.

‘Yes,’ he nods, sure Kei is looking at him even if he can’t see him. ‘Wanna be your slut.’

‘Shh, you are. Just mine.’ Kei reassures him. ‘You’re so good for me, letting me fuck you. Gunna let me come in you too?’

Tetsurou can only keen in response, hips twitching backwards at the request. Kei laughs.

‘God you’re perfect. My alpha, bet you would beg me to breed you if I asked.’ Tetsurou feels his stomach drop at that, shooting precariously close to the edge.

‘Anything. Anything for you

Kei.’ He blurts out. Kei’s pace stutters then, his head dropping until his forehead was pressed into Tetsurou’s back, pressing a kiss to his heated skin.

‘Tetsu, you fucking sap.’ He hisses, fondness creeping in his tone. ‘Come from my cock and maybe I’ll be nice and let you

Knot me later.’

Tetsurou whines again, nodding his agreement. Kei straightens back up, continuing his heavy thrusts until they’re both falling off the cliff together, Tetsurou staining the sheets as he comes untouched, Kei spilling inside of him.

Kei pulls back long enough

To allow Tetsurou to roll to the side before he plops himself directly on top of him. Tetsurou lets out a small oof, arms curling instinctively around him. They bask in the afterglow for a few minutes, Kei reaching up to thread his fingers through Tetsurou’s sweaty hair,

Pressing chaste kisses to his chest as his heart rate slows back to a normal pace.

‘Soo, ready for round two? I recall a mention of me knotting you?’ Tetsurou prompts, wagging his eyebrows at Kei who only snorts in response.

‘As soon as you can get it back up, old man.’

‘I

Know just the thing,’ Tetsurou smirks, ignoring Kei’s yelp as he sits up and flips their position. He manhandles Kei until he’s in the mirror image of Tetsurou from before, face down ass up. ‘Can I eat you out while we wait? It’ll speed up my recovery, promise.’

‘I suppose that

Would be fine,’ Kei tries to sound disinterested but he can’t stop the waver in his voice as Tetsurou trails his fingers over where his slick is already starting to pool.

‘Perfect.’ Tetsurou dives in with no prelude.

End.
