Sick And Twisted

5. ya, to lazy

Katsuki couldn’t wait another second, he wanted to be inside the omega. He raised up off his heels and lined his cock up with Izuku’s entrance. He grasped Izuku’s hips and slammed himself in. No prep other than what his tongue had accomplished. Instantly they were flesh to flesh. 

“AHHHH! FUCK!” Izuku screamed out. It was painful, but it’s what his body craved so bad. The pain, the fullness, the warmth against his skin. As quickly as Katsuki entered he was gone again, pulling out completely before slamming in again. 

“AHH fuck Alpha, so big, mmph harder Daddy  harder! ”

Katsuki came to a halt, “the fuck did you just say?”

Izuku froze, and instantly went into a cold sweat. What did he just say? ‘ Fuck.. Did I seriously just call him Daddy!? Oh god.’ 

“Answer me.”

“w-what?” Izuku tried like hell to avoid the answer he knew Katsuki was looking for. ‘ Fuck, what was he going to do. This is bad. He’s  gonna kill me. This is so bad.’ 

“You know exactly what I’m talking about. What the fuck did you just call me?”

Izuku stayed silent for a second and Katsuki pulled out again completely. Before Izuku could even form a thought of what the alpha was going to do to him Katsuki slammed back in again, this time with enough force that Izuku’s body slammed forward, face sliding against the floor as he tried to keep his position, not wanting to piss the alpha off any more.

“Izuku.” Katsuki growled out in a demanding tone.

‘ oh shit.’  The way his name rumbled off the other’s tongue sent shivers down his spine, terrifying, yet exhilarating. He couldn’t help but comply,  “.... Daddy...”

“.... Fuck .....  Again.” Katsuki couldn’t  believe  the nerd fucking called him that. Even more so, he couldn’t believe how much he liked it.   Izuku though, hadn’t caught on just yet..

“Daddy?”

“Fuck...shit.... you filthy slut. You just keep on surprising me.... Say it again.” He pulled out one more time completely as he waited for Izuku to acquiesce. It finally clicked, Izuku realized he wanted to be called that. He was shook.

“Daddy! Mmm.. Fuck your slut Daddy! Make me scream!”

Katsuki let out a loud deep growl and slammed back into Izuku, this time not stopping for a second. He fucked him mercilessly, slamming in and out as hard as he could. Izuku screamed and moaned as he tightened around Katsuki’s cock. The alpha lost all control, the heat, the sounds coming from that boy’s mouth, that name, the tightness surrounding him, their scents mixing together, he was gone, just pounding away as hard as he could. Sparks were leaving his fingertips, crackling at the skin beneath them, leaving small burns on the omega’s waist. He leaned over just enough so he could wrap one hand around Izuku’s throat, knowing damn well that’s exactly what the boy wanted. He yanked him upwards so he was now on his hands and knees, and bit down on his shoulder blade drawing blood once again. He lapped it up and continued leaving bites and bruises everywhere his mouth would reach. He then sat back up and wrapped his other hand around Izuku’s throat. He stopped for a mere second so the boy could get a breath before using his throat like a fucking handle to pull his body back onto himself, thrusting over and over, harder and harder. Surely there would be bruises on Izuku’s neck but neither of them cared. After a minute or so of this Izuku let out a fucked out moan and arched his back. Katsuki felt izuku clench around his cock so he increased his speed. Knowing the omega just came, he wanted to torture the boy a bit. He took his right hand, laid it on Izuku’s lower back, and ignited his quirk resulting in a beautiful deep red burn in the shape of his hand. It was a non-vocal way of getting his point across, coming without permission is NOT allowed.

  Izuku gasped for air, panting like crazy before looking over his shoulder with a smirk, “Just...like that...Daddy....  Fuck.  Do it.. Again.” Katsuki complied, doing this again and again. When he would let go of his throat so the omega could breathe, he’d grab a hand full of hair, smack his ass, or he’d send small blasts to his back, “Come for your Alpha!”  Those four words sent Izuku over the edge every time. Spurts of milky white splashing the concrete below him again and again. He was at his limit, exhausted, but still couldn’t get enough. Katsuki wasn’t seeming to give him any time to catch his breath either. He was being relentless with his pounding.

Katsuki pulled out of the omega and flipped him over, being sure to move over just enough to avoid the lake of white beneath them. He grabbed Izuku’s legs and threw them over his shoulder right before slamming back into the omega’s heat. Using his thighs for leverage he began to ram into the boy again. Being inside him was the most exhilarating feeling. He didn’t want it to end, he was going to milk this for everything it was worth. 

  Izuku was hardly conscious by now, just a mumbling repetitive mess of moans and whines. “Kacchan” and “Daddy” being the only audible words he was able to form. Katsuki held true to his word, he fucked Izuku until the only word he knew was the alpha’s name, literally. 

The alpha knew he was getting close, he dropped Izuku’s legs and leaned in close so their chests were almost touching. He had one hand on each side of the omega’s head, staring into lust ridden green eyes beneath him. Those blood-thirsty crimson eyes flickered from the omega’s own emerald eyes, down to his neck, the alpha craving to mark what’s his. Katsuki’s mind screamed ‘ NOOO’   but his instincts screamed ‘ YESSSS,’  an internal war waging itself. He started to lean in against his will, nearing closer and closer to the scent gland his alpha craved to sink its teeth into. Izuku’s eyes went wide, his body reacting without consent. He tilted his head giving the blonde complete access to what he wanted. His eyes slammed shut and bit down on his lower lip knowing full well this was happening no matter how much he was internally screaming for it not to. Katsuki closed in on the scent gland that was pouring pheromones into his face, begging to be marked. The alpha latched onto the boy's neck, muscling all his strength to keep his canines at bay as he began sucking at the sweet spot, coaxing every bit of the bitter spice he could out of him. It took every bit of restraint he had not to bite down and claim the omega right then. He could feel his knot ready to slip into Izuku as he sucked, nipped, and licked at the delicious boy beneath him. Katsuki gave a few more unrelenting thrusts as he lost all control, sinking his teeth into the omega’s neck, claiming him completely. Marking the omega as his and only his. He let out a muffled possessive growl as he released into the smaller male, locking them together.

“AHHH, FUCK...NGgghh” Izuku screamed out as the knot stretched his insides beyond his limits, the alpha’s teeth sinking into his skin. It was almost unbearable, but the pain sent sparks of pleasure straight up his spine causing him to cum one last time. Katsuki released his canines from Izuku and stared as the blood dripped into the crease of his neck. He lapped it up and nuzzled into the boy’s neck with a prideful grin on his face, inhaling the delectable scent he couldn’t seem to get enough of. Both boys, utterly exhausted from all of the events that had transpired, drifted off snuggling close to one another.
