Chapter 4 (smut warning)

Eijiro opened his bedroom door and pulled katsuki in closing the door behind them locking and breathing heavily.

——————————————————————

Katsuki looked up at the taller male as the scent surrounded both of them. He saw how hard the other was breathing, getting more and more. "Do I have consent pup~" Eijiro said looking down. Katsuki's omega broke through his senses, wrapping his arms around his neck "Mm.. yes~" he purred back. Eijiro kissed katsuki wrapping his arms around his waist

Katsuki quickly kissed back, his omega the one in control at this point. Eijiro walked over to the bed not breaking the kiss. Katsuki followed the other, laying back as he felt his knees hit the bed. Eijiro started to kiss the omegas neck until he got to his scent gland and started to like it "can I mark you pup~?"

Katsuki let off small needy whines as the scent of the alpha started to seep out and surround him. "Mm~ Yes!~ fuck~ alpha mark~ please~"

Eijiro kissed it a few more times before biting the omega hard enough to leave a mark. Katsuki braced himself for the feeling and let out a pleasured whine as he had been bit, gripping at his hair. Eijiro started to unbutton katsuki guard suit as he licked up the remainder of the blood. Katsuki started to help with ditching the other's clothes, unbuttoning his shirt messily.

Once the alpha got others shirt off he started to fumble with his pants kissing down his chest. Katsuki started to produce a different scent, it was stronger, the scent his omega was letting out was filled with need. Eijiro sniffed the air and started going faster on the others pants finally get them off as well as his own clothes

Katsuki's omega was letting off a needy scent that was meant to draw an alpha to the breaking point until they were in a rut. That's what he wanted. Eijiro looked at katsuki his eyes fill with lust "pup I'm trying to have a little control and not hurt you and your scent isn't helping that" Katsuki wasn't really thinking of that, that lust in his eyes drove him more. His omega was thinking for him, not his rational mind.

Eijiro took off katsuki's underwear and immediately put a finger in katsuki's hole. Katsuki let out a sharp whine in the pleasure of the feeling. It hurt. But it felt good. He liked the pain. Eijiro smirked as he thrusted and added another finger. Katsuki let more pleasure whined pour from his lips.

After a few more thrusts of his fingers Eijiro took them out, took his pants and underwear off and lined himself with katsuki. Katsuki braced himself, not knowing how big or wide Kirishima was, all he knew was he wanted this. He really wanted it. Eijiro immediately went in without warning and groaned a bit from the pleasure. Katsuki gasped whenever he pushed in when moaned out loudly in a mix of pain and pleasure

Eijiro started moving when he heard his omega moan "god pup~ you feel good around me~" he said thrusting fast. Katsuki pushed his hips down to meet the trusts of the red head, moans seeping from his throat as his scent only got stronger. Eijiro kept thrusting but as he did so he kissed his neck and left marks all over his neck and chest.

Katsuki could tell there were going to be marks, he knew he'd get questioned about what they were as well, but he could have cared less in the moment. After a few more thrusts Eijiro looked at katsuki in the eye "pup I'm gonna finish" he groaned out in pleasure.  Katsuki let out pleasured whines and whimpers as he felt himself getting closer to the edge "Fuck!- Ah~ M-Me too!~" Eijiro groaned and moaned as he finished in katsuki, slowing his thrusts. Katsuki bucked his hips up into the air as he released, the white substance falling onto his chest.
