Summary:

MIND THE TAGS!!! This is very explicit

Notes:

My first time writing a Yandere type fic!!

This is the prompt that started it all by the amazing Jupiter @jupiterloveu on Twitter

 Katsuki has always loved Izuku. The pretty omega had been his since they were pups, and he wasted no time making it true when he proposed to him. However, Katsuki lost him by being a fool who thought the freckled would wait for him when he chose his fortune over marrying and mating with him. The alpha never gave up his obsession with his ex, no, he continued to stalk Izuku over the years. After all this time, however, Katsuki was still completely and irrevocably in love with the omega. He refused to date or even fuck another person. Nobody was good enough for him except for Izuku.

In the same since Izuku was still completely in love with Katsuki. His heart would always belong to the alpha, but he refused to wait on a man who chose money over him. With that thought in mind, he began to move on from the alpha by going on dates. Recently, he'd been out with an alpha named Neito. The alpha treated him well despite never measuring up to Katsuki, but tonight was it. He was finally going to let Neito fuck him. Izuku was more than aware his ex-indulged in keeping tabs on him. Katsuki had always been possessive over him, but Izuku didn't mind not when he was treated so well by the alpha. In fact, he adored the devotion and gave it back tenfold. Some could even say their love was crazy almost psychotic even. Not that they cared. All that mattered was their devotion to one another.

Honestly, it shouldn't have surprised the little omega when he was getting ready for the date with Neito and was slipping on his lingerie and was knocked out.

Izuku groans as his eyes flutter open and take in the fact, he's on his ex's bed laying on his silk sheets writs bound. That's also the moment his eyes lock onto Katsuki staring down at him with carmine eyes full of love, anger, and lust.

"Kacchan?"

Tears are sliding down Katsuki's cheeks as he asks roughly, "Why the fuck were you going to let that piece of shit fuck what's mine? You know how much I love you Izuku. You're mine! Why would you betray me this way?"

Izuku not one to hide or lie to Katsuki ever simply admits, "You left me Kacchan. I'm not going to wait when I deserve better. You made your choice," the omega pauses giving him a sly smile, "Plus, I'm horny and he was available."

Katsuki lets out a deep growl as he holds up a knife stalking forward and letting the blade caress along his skin, "You belong to me, Izuku. Just like I fucking belong to you," he slips the blade beneath the panties and as he cuts through the fabric as he growls," That means nobody is allowed to touch you but me ."

After cutting the panties off the alpha and lets the blade gently graze the skin. Not cutting him, no, just the feel of the cool metal of the blade caressing the skin of his cunt.

Izuku, the slut that he is when it comes to blonde alpha, feels himself dripping wet just from the act itself. Begs as tears build up in his eyes, "Kacchan, please! Please Alpha I want you to fuck me! Claim me as yours!"

Katsuki growls low in his throat as he tosses the knife away before climbing on top of the omega and guides his cock to his cunt thrusting in hard and deep.

"Nngh! More! Kacchan please!" The omega cries as the blonde rolls his hips pounding him into the mattress, "M'sorry, m'sorry I ever left you," Katsuki groans as he leans down showering his face and throat with kisses.

He licks a stripe along a freckled throat sucking at his scent gland, "I love you, fuck, Izuku you're mine!" Izuku whines and moans as he withers beneath the larger man, "Y-Yours! Only yours! Kacchan mark me! Bite Alpha!"

Katsuki groans, "Marry me, Izu. Please fuck marry me," all the while Izuku's cunt squeezes around his cock covering his thighs and sheets beneath them in his slick, and the omega wines, "Yes, yes! Wanna marry Kacchan!" The alpha snarls nipping his throat and dips a hand between them teasing the bundle of nerves, "Cum for me Omega. Cum on my cock and I'll claim that pretty throat that belongs to me."

Katsuki was feral with the need of making Izuku cum for him. The omega screams as a well-timed thrust deep inside his cunt paired with rough fingers pinching his clit has his vision whitening out as his orgasm hit. Only to be hit with another as sharp fangs pierce his skin.

"Alpha! M-mine!" He cries as his eyes roll back. Katsuki pulls away noticing the blood he leans down licking it away before taking the omega's mouth in a sloppy kiss filled with tongue letting the omega taste the copper of his own blood making him whimper.

"Your turn Omega," he growls against his lips before moving to allow small fangs to pierce his own throat. Katsuki groans as the pleasure of being claimed and Izuku's tight little cunt tightens around his cock as they both reach their climax.

However, the blonde continues to fuck the fucked-out Omega beneath him. His cunt was dripping with slick and cum as the alpha growls, "Mine. I'll kill anyone who fucking tries to mess with you, Izuku."

All the while the greenett is a mess of whimpers and moans as he slurs his alpha's name begging for his cunt to be filled. By the time the two are done, it's well past daylight. Katsuki rolls onto his back with the smaller man asleep on top of him as his cock stays buried deep in his cunt.

A few weeks pass after the two had gone public of becoming engaged and it wasn't long after the two announced Izuku was expecting their first pup despite being on birth control for years. But really it was no surprise after how much cum the alpha had pumped into his abused cunt the night, he brought him back to his place.

The alpha's parents were against the two being mates, but strangely a week after announcing talks of disowning Katsuki the two died in a tragic accident leaving everything in the will their son. Neito had weirdly disappeared without a trace, but Izuku didn't care. Not when he finally had Katsuki back and they were expecting their first pup. All that mattered was them finally being together and madly in love despite their psychotic tendencies. And if Izuku ever requested Katsuki to cut panties off him and tease his skin above his cunt with the blade on special occasions, well that was nobody's business but theirs.
