"Alpha..." Izuku whimpered as another burning wave of pain travelled his whole body. "Need you..." He whined, his face burrowed into Katsuki's neck so that he could inhale the alpha's soothing scent.

Kirishima and Kaminari had left, leaving Katsuki and Izuku alone. They didn't have any other choice than to use Kaminari's room since Izuku's arousing pheromones would attract any alpha close by as soon as they would take a step outside. They couldn't take the risk.

"I know, kitten." Katsuki answered. "I'm gonna take care of you, don't worry." He told Izuku as he gently petted the omega, running his large hand through Izuku's soft green curls.

Izuku let out a sweet purr at the touch before looking at Katsuki with his big green eyes. They were glazed with passion and full of lust, the current state of deep arousal of the omega clear as day.

"Want you..." Izuku murmured as he began to kneel between Katsuki's legs.

Katsuki immediately grabbed Izuku's shoulders to prevent the omega from nuzzling his clothed cock. "No. Don't do that." He told Izuku but, as always, the omega didn't like being stopped. "Want alpha..." He whimpered, his beautiful emerald eyes begging Katsuki as an adorable pout appeared on his pretty face.

"You know we can't do this, kitten..." Katsuki bit his lips at the sight.

It wouldn't be the first time Izuku had tried to suck him off but Katsuki didn't know if he would be able to keep control of his instinct if he let it happen. Plus, he wasn't sure if receiving a blow job from the omega when he was in heat felt right.

But Izuku didn't care about all of this. The omega was determined to have what he wanted. "Alpha, please..." He kept begging, his pretty mewls tantalising and absolutely irresistible . "Want to taste alpha..." He sexily whimpered and, even if Katsuki tried really hard to resist to Izuku's seduction, the alpha couldn't prevent his cock to get incredibly hard inside his pants.

"Fuck." He cursed under his breath as his pulsing erection became painful against its restraint. Holding back was getting really hard when Izuku was being this entrancing.

"Alpha..." The omega let out another sexy moan and Katsuki finally had it. "Just a little, okay?" He inevitably gave in, his desire for Izuku way too strong to be ignored right now. Katsuki needed to feel Izuku's pretty lips around his dick or he swore he would lose his mind.

"Yes!" Izuku didn't need to be told twice. He happily nuzzled Katsuki's still clothed erection, a low purr rumbling out of his chest as he inhaled the musky scent of his alpha. He then looked up right into Katsuki's crimson eyes, while using his teeth to slowly unzip Katsuki's pants.

Katsuki had to use all of his willpower to not suddenly burst from the sight alone. Izuku really was going to be the end of him if he kept turning him on more and more. Katsuki was so hard right now that the mushroom-like head of his huge cock was coming out from the top of his boxers, the tip looking swollen and red.

Izuku stared at it with almost wonder. "So big..." The omega murmured, his comment triggering a smug smirk to appear on Katsuki's face. "Just for you, kitten." The alpha huskily answered.

Izuku finally took Katsuki's cock in his hands and began to put small kisses on the tip, sensually, before giving some kitten-like licks to the head. He looked right into Katsuki's crimson eyes as he did, a look of pure innocence shining inside his emerald eyes.

"Damn..." Katsuki husked out as he intently watched everything Izuku was doing. He didn't want to miss anything. "You look so pretty with your lips on my cock." He said as he started to gently run his hand through Izuku's green curls. "So fucking adorable."

The sight of Izuku licking the tip of his cock was such a turn on. Katsuki didn't think he could possibly be more aroused. And the sensations of Izuku's tongue on his sensitive head... they were simply amazing.

"Careful. Don't use your teeth, kitten." Katsuki said when Izuku decided to take more of the alpha inside his mouth. He kept a hand in Izuku's hair, watching as more and more of his dick disappeared inside the omega's hot wet mouth.

"Fuck." He cursed when he could feel his cock hit the back of Izuku's throat. "No gag reflex, huh? That's fucking hot." He smirked. Izuku wouldn't have any trouble deep-throating him.

The omega started to bob his head, closing his emerald eyes and humming as he began to suck Katsuki off. It looked like he really enjoyed the taste and feel of the alpha inside his mouth. He swirled his tongue around the shaft, while perfectly moving his head up and down.

"Seems like you really like my dick, hm?" Katsuki amusingly husked out. The way Izuku was sucking on his dick was so adorable, like it was the best treat the omega could ever ask for.

Izuku opened his green eyes to look at Katsuki at the alpha's words, and Katsuki didn't know how it was possible, but the omega still managed to look incredibly cute and innocent even with a cock inside his mouth. His emerald eyes were big and beautiful, filled with purity.

"Fuck, you're so damn cute." Katsuki let out a low possessive growl at the sight. He felt like he was going to explode soon if he didn't do anything so he suddenly pulled his dick out of Izuku's mouth, before bringing Izuku's face to his and fiercely pressing their lips together in a passionate closed-mouth kiss.

"You did good, kitten." He then murmured once they parted lips and locked eyes.

"I pleased alpha?" Izuku adorably asked, his beautiful emerald eyes sparkling as he expectantly looked at Katsuki.

Katsuki couldn't help but smile fondly at the omega. "Yes, a lot." He didn't hesitate to answer. What Izuku had done to him had felt amazing. The only reason he had stopped the omega was because he was going to burst inside his mouth if he kept going.

"Now, it's my turn to take care of you." He suddenly said in a low seductive voice.

Izuku didn't have time to answer that he was already pushed against the mattress. His shirt was removed in no time before warm lips suddenly found his neck. "Ngh..." He softly moaned at the sensation, his hands instinctively burying themselves into Katsuki's blond locks.

Katsuki began to press languorous kisses all over Izuku's delicate skin. His crimson eyes landed on the omega's sensual pink nipples and Katsuki couldn't resist closing his lips around the perked buds.

"Mhw..!" It drew a pretty mewl out of Izuku's mouth and Katsuki smiled in satisfaction. The alpha kept teasing Izuku's nipples, sucking on them and enjoying all the cute whimpers it triggered out of Izuku.

"Looks like your nipples are sensitives, kitten." Katsuki seductively murmured with a sexy smirk on his handsome face.

He then decided to keep trailing kisses down Izuku's body, his lips caressing the omega's abs and reaching Izuku's cute belly button. "Ahn..!" Izuku slightly shivered at the sensation, a small moan slipping past the omega's lips as Katsuki licked his navel.

"Your belly is sensitive, too." Katsuki noticed. He was loving how everywhere he was kissing, Izuku was sensitive. All of the omega's reactions were adorable and highly entertaining.

"What about your thighs?" He wondered, before suddenly taking Izuku's pants off in one swift movement and lifting one of the omega's leg to his mouth. He ignored Izuku's cute yelp and brought his lips to the omega's inner thigh, beginning to put sultry kisses on the soft pale skin.

"Mhn!" Izuku let out a loud moaned when Katsuki sucked on his inner thigh. The alpha watched with satisfaction as a dark hickey appeared there, a smirk taking over his features when he thought about Izuku's reaction when the omega would discover the hickey tomorrow...

With the position they were in, Izuku being perfectly naked and legs spread, Katsuki could see everything. He could see Izuku's hard member, precum already dripping out of the omega's pink swollen tip. He could also see Izuku's entrance and all the slick that was leaking out of it, the transparent liquid dripping down the omega's thighs.

Katsuki wondered if Izuku's slick tasted as good as it smelt...

"Nghh!" Izuku lewdly moaned when Katsuki's tongue suddenly reached his entrance. The omega arched his back and threw his head back on the bed, his lips parting in a moan as his body shuddered in delight.

"Fuck, you taste so good." Katsuki husked out between licks. Izuku's slick tasted absolutely delicious, like vanilla and cinnamon roll, the same as its enticing smell. "So damn sweet." The alpha appreciatively hummed as he began to eat Izuku out, sinking his tongue past Izuku's tight muscle ring.

"Alpha! Awh!" The omega instantly whimpered loudly at the sensation. His emerald eyes closed in bliss and his whole body quivered, his hands fisting the sheet around his head. "Feels good!" He moaned in utter pleasure as Katsuki's tongue divinely massaged his inner walls.

Izuku's entrancing mewls were turning Katsuki on so much. The way the omega was trembling underneath him was so satisfying and arousing that Katsuki could feel his throbbing cock pulse in response. He felt like he was going to explode; precum was continuously leaking out from the tip of his dick.

Using one arm to keep Izuku's legs spread, Katsuki used his other hand to grab his pulsing cock. He began to give himself long rapid strokes to jerk himself off at the same time he tongue-fucked Izuku. He could tell the omega was close but so was he. Izuku's blow job had already drove him so close to the edge. He only needed a little more stimulation to reach his climax.

"Alpha..! I'm gonna..!" Izuku only had time to warn before suddenly coming without even having his dick touched. "Ngwhh!" The omega loudly moaned as he orgasmed, his back arching up and his entire body quivering in pleasure. His legs trembled and tears escaped his emerald eyes, the intensity of his orgasm completely overtaking him.

Katsuki stopped eating Izuku out to instead focus on jerking himself off. He eagerly stroked his cock, his crimson eyes not leaving Izuku's post-orgasm blissed out face one instant as he did. Izuku looked so beautiful with tears rolling down his flushed cheeks, soft pants leaving his pink parted lips, that Katsuki didn't even need to jerk off long before suddenly coming in turn.

"Fuck..!" He loudly growled as loads of cum erupted from his cock, landing on Izuku's belly and covering the omega's own milky semen.

The alpha then found himself panting heavily, his heart pounding rapidly inside his chest as he took some time to recover from the amazing orgasm he had just had. Sweat was glistening on his forehead, rendering his blond locks sticky but, overall, Katsuki had never felt more satisfied once in his life before.

"Damn, that was something." He smirked as he looked at Izuku's now passed out form sleeping on the bed.
