Katsuki pinned Izuku against the door of his room as soon as he had locked them inside. He didn't waste any instant to claim Izuku's mouth, their lips slamming together and their tongues immediately joining the other.

Izuku moaned into the kiss as he wrapped his arms around Katsuki's neck. Katsuki's large hands moved to wrap around his slim waist while the alpha slowly made them walk toward the bed, their lips never parting. He sat on the edge of the bed and pulled Izuku on his lap so that the omega was straddling him.

"You smell so fucking good." He husked out as he stopped kissing Izuku on the lips to instead start to press languorous kisses on the omega's neck.

Izuku had removed his scent blockers on the way to Katsuki's room. He wanted Katsuki to be able to smell his irresistible scent. He knew how much the alpha liked it.

"Kacchan..." He moaned as Katsuki kept kissing his neck. It felt so good and his heart was beating so fast inside his chest. Katsuki's hands were now holding his ass in a tight grip. Things were going so fast Izuku wasn't sure if he could even keep up with everything anymore.

"Wait, Kacchan-" He suddenly said when Katsuki began to slip a hand behind the waistband of his boxers.

Katsuki immediately stopped what he was doing. He placed his hand back on Izuku's ass and removed his lips from Izuku's neck to instead look at the omega. "What is it?" He asked, a smirk taking over his handsome features when he saw the dark blush covering Izuku's pretty face.

"You're getting shy on me now, Deku?" He chuckled deeply.

"I'm not..!" Izuku replied right away but his embarrassment was written all over his face. "It's just..." He stammered, his beautiful emerald eyes looking everywhere but into Katsuki's crimson eyes.

"Too fast?" Katsuki asked. He had forgotten in the heat of the moment that Izuku had actually never done anything more than kissing, since the omega never remembered what happened during his heat. Katsuki should slow things down a little if he didn't want to scare Izuku away.

He gently grabbed Izuku's chin and pressed their lips together again. He kissed Izuku with as much passion as they had shared just moment ago, but this time it was gentler and slower. Their tongues sensually danced together and their breaths slowly mingled together.

When they parted lips, Izuku was softly panting. Katsuki pressed their foreheads together and waited some instant for Izuku to calm down. "Want to know what we do when you're in heat?" He asked in a seductive murmur.

Izuku felt his heart flutter inside his chest. He wasn't expecting this question and slightly blushed as he felt Katsuki's intense gaze on him. Actually, he had already wondered what did they do when he was in heat. He trusted Katsuki so he wasn't scared that the alpha did anything he wouldn't want to, but he was curious to know what kind of things they did together...

"Tell me." He couldn't resist answering in a whisper.

Katsuki smirked. If there was one thing he was sure about, it was that Izuku could never win against his curiosity. "I usually jerk you off." He stated right from the start without beating around the bush. "Sometimes I eat you out."

Izuku couldn't help but blush a deep red at the words. The thought of Katsuki jerking him off or going down on him was flustering him to no end. But, at the same time, it was turning him on so much. Only imagining Katsuki's head between his legs was enough to send butterflies to his stomach.

"But most of the times I finger you." Katsuki said before going more into details. "You always let out pretty mewls when I do this. You clench on my fingers so tightly while shaking in pleasure underneath me." He described with a sexy smirk, his voice deliberately low and seductive.

"Oh god..." Izuku whimpered in response. Thrills were traveling his whole body while his heart raced inside his chest. Flutters were filling his belly and slick was leaking out of his entrance, surely soaking his pants.

"Want to try it?" Katsuki sensually asked. He could smell Izuku's arousal and could tell the omega had already started to produce slick. Knowing it was his words that were triggering such a reaction from Izuku was turning Katsuki on so much.

"You just have to tell the word and I'll take care of you..." He murmured right into Izuku's ear with his low husky voice.

Izuku couldn't restrain the moan that escaped his lips. "Yes, I want to try." He breathlessly answered, the state of arousal he was currently in simply behind words. He wanted Katsuki to touch him and now.

Katsuki smirked in triumph as he slipped his hand back into Izuku's boxers. This time he was cautious to not go too fast so that Izuku wouldn't stop him again. He would take things slow for Izuku and pleasure the omega like no-one else could.

He began to slowly circle his fingers around Izuku's entrance to make sure the omega was relaxed. He softly stroked Izuku's most intimate part and was pleased to feel how much slick the omega had already produced.

"Ngh..." Izuku softly whined at the sensation. He tightly held on to Katsuki's shoulders and buried his face against the alpha's neck, his heart beating incredibly fast inside his chest. He was nervous, of course. He couldn't help but be even if he trusted Katsuki with all he had.

"It's okay. Stay relaxed, kitten." Katsuki gently murmured as he kept softly caressing Izuku's entrance. He wanted Izuku to be as comfortable as possible. It was an important step in their relationship and Katsuki couldn't afford to screw it up.

"You just called me kitten..." Izuku whispered as he looked up at Katsuki, his emerald eyes wide with surprise. "Is it how you call me when I'm in heat?" He breathlessly inquired.

"Yeah." Katsuki responded and Izuku couldn't believe his ears. "Say it again." He immediately demanded.

Katsuki smiled. "You like it when I call you kitten?" He repeated and Izuku almost moaned at the sound of the affective pet name rolling off Katsuki's tongue. He was so used to being called Deku that hearing Katsuki call him kitten felt amazing. It was sending shivers all over his body.

"Again." He asked.

"You're so damn cute, kitten." Katsuki chuckled. If he had known how much Izuku liked being called kitten, he would have called the omega like this sooner.

"Ngh..!" Izuku suddenly whimpered when Katsuki finally slipped a first finger inside him without any warning. The omega immediately hid his face against Katsuki's neck again, his grip on the alpha's broad shoulder tightening at the intrusion.

"You okay?" Katsuki quietly asked, his mouth only inches away from Izuku's ear. His low voice was making the omega quiver in delight.

"Y-yeah... it feels a little weird..." Izuku timidly answered. It didn't hurt but it didn't feel particularly good either. At any rate, his heart was beating so fast right now he wasn't sure if he could properly think anymore.

"Really?" Katsuki smiled. He knew he would have to sink his finger deeper in order to make Izuku feel good, but one step at the time. He waited some instant for Izuku to relax again before silently murmuring. "I'm adding a second finger."

"Nwhg..." Izuku let out a small whine as Katsuki sank another digit inside his heat. This time he definitely felt fuller with two of Katsuki's thick fingers inside him. He could feel his inner walls stretch to accommodate the digits. It wasn't an agreeable sensation but it still wasn't painful either.

"Does it hurt?" Katsuki asked again lowly. He wanted to make sure Izuku was okay.

"N-no, it doesn't..." Izuku timidly answered as his heart beat loudly inside his chest. He buried his face deeper into Katsuki's neck and held on tightly to the alpha. He couldn't believe this was happening. Katsuki was really fingering him. The alpha had started to slowly move his fingers inside him and Izuku couldn't help but quietly whimper at the sensation.

"You feel way tighter than when you're in heat." Katsuki seductively whispered right into Izuku's ear and the omega felt his heart flutter at the lewd words.

"Oh god..." He started to let out a flustered whine, when Katsuki's fingers suddenly reached a spot inside him that made his whole body shudder, the feeling triggering a surprised moan to escape his lips without his own accord. "Ngh! W-wait!" His stomach fluttered and his body slightly tensed up, his emerald eyes shutting closed as Katsuki stimulated the same spot again.

"What? Feels good?" Katsuki smirked. Izuku's reaction was so adorable. Seeing the omega being shy and timid was a nice change compared to how bold he usually was when he was in heat.

"Yes..." Izuku shyly answered and Katsuki grinned in pride. He unexpectedly leaned in to slightly nibble on Izuku's earlobe before sexily whispering.

"I already know all of your sweet spots, kitten. I'm gonna make you feel so good."

Izuku felt his heart jump inside his chest and butterflies erupted inside his belly at Katsuki's words. "Nwh! Kacchan..!" He suddenly began to moan louder as Katsuki abruptly increased the pace of his fingering, the alpha's digits continually hitting Izuku's prostate perfectly.

"That's it, kitten. Call my name." Katsuki deeply husked out. Hearing Izuku moan his name instead of being called alpha was turning him on so damn much. This time Izuku knew who was pleasuring him. He wasn't simply looking for an alpha to mate with. No. He had allowed Katsuki to touch him and Katsuki couldn't be prouder.

"Damn, you're sucking my fingers in so much." He growled lowly as he felt Izuku's inner walls twitch around his fingers. The omega really was tighter than when he was in heat. His insides felt so warm and tight. So soft and wet. Katsuki was getting more and more aroused by the time, his cock now hard and throbbing inside his boxers.

"Give me your lips." He suddenly grabbed Izuku's neck and brought Izuku's face in front of his, before abruptly capturing the omega's lips in a possessive kiss.

Izuku instantly melted into the kiss. He kept moaning, his irresistible mewls swallowed by Katsuki's mouth. He hugged Katsuki's neck tightly as his whole body quivered in pleasure. His head was starting to spin and tears were beginning to escape his beautiful emerald eyes.

"Ngh!" He suddenly moaned loudly when Katsuki used his other hand to grab his member that had stayed untouched until now. Katsuki fingered and jerked Izuku off at the same time, driving the omega insane with intense pleasure.

"Kacchan! I'm close..!" Izuku lewdly whimpered as he held Katsuki for dear life. Warmth was quickly building inside his stomach and threatening to explode any moment now.

"You can come, kitten." Katsuki seductively murmured into Izuku's ear and Izuku just couldn't hold back anymore.

"Awnh!" He suddenly came with the most beautiful moan Katsuki had ever heard him let out, his entire being quivering as he released in Katsuki's hand. His back arched up and his insides tightly clenched around Katsuki's fingers, tears of bliss rolling down his cheeks as he orgasmed.

Katsuki almost came inside his boxers at the sight. Izuku's orgasmic face was so beautiful and the way the omega trembled in his arms was simply addictive. He kept stroking Izuku's member a few last time, before stopping and cautiously pulling his fingers out of the omega.

Izuku was now panting on Katsuki's shoulder, his arms still tightly wrapped around the alpha's neck. Katsuki grabbed some tissue on his bedside table to wipe the cum and slick off of his hands before making Izuku and himself lay on the bed. He held the omega close to him, letting him some instant to recover from his orgasm.

Katsuki was still hard but he didn't care. He'll jerk off later. Right now, the most important was Izuku. He hadn't given Izuku an orgasm only to have the omega return the favour. He had simply wanted to touch and pleasure Izuku, nothing more. They would see about doing other things another time.

"You okay?" Katsuki eventually asked as he began to gently run his hands through Izuku's green curls.

Izuku let out a soft hum in response. "Yes..." He whispered, his face still hidden into Katsuki's neck. It was so adorable how he was clinging to the alpha.

Katsuki gently took Izuku's face into his hands to look at the omega. He gazed into Izuku's beautiful emerald eyes, taking in each of his pretty features inside his mind, before pressing a soft kiss on the omega's forehead.

"Did you like it?" He lowly asked and smirked when Izuku furiously blushed at the question.

The omega promptly hid his face into Katsuki's neck again as a flustered whine escaped his lips. He closed his eyes tightly, memories of what had just happened flooding inside his mind.

Katsuki had been really gentle with him. More than he would have expected. He had took things slow for him and had even called him an affective pet name. What he had done to him had felt amazing, like nothing Izuku had known of...

"Yes, I really liked it..." He eventually confessed in a whisper. "It felt really good. Thank you, Kacchan..." He timidly thanked Katsuki for having given him an amazing orgasm.

Katsuki smiled at Izuku's words. That was all he had wanted to hear.
