Izuku POV:

'Just what did I do to cause this?' After about half an hour into the night, I began watching Nemuri and Mt. Lady start drinking notable amounts trying to one up the other. The strangest thing was, I initially didn't expect this to happen with the mood around us when the date started being so calm and relaxed.

"I'm telling you that there's noooo way you can out drink me. You couldn't *hic* out drink drunky over here." Mt. Lady pointed to Kamui Woods who was holding his head to the table looking like he was ready to throw up at any moment.

"You think that, but you can't passibly beat me." Nemuri poured another glass for us with Kamui Woods opting for water he had.

"Alright. I think we drank enough. Both of you look like you should drink a little water."

"But Izuuuu. I want to show this tramp I'm better."

"At what? Being a slut that you have to cradle rob this kid?"

"Says the woman that lets men take pictures of her ass and gives a suggestive pose doing it. If anyone was a cradle robber here, I'd look at you." Nemuri pointed fingers at Mt. Lady with a bit of satisfaction in her voice for both me and Kamui Woods to see where this was going.

"You know what then, one last round. Let's see if you can hold your liquor better than me. Loser pays for the meal and drinks."

"You're on." The two had one last glass of red wine poured for them with it looking to me as if both were going to drop at any moment. They counted to three before drinking their glass and waiting for the other to drop. In a few moments, Mt. Lady fell face first on the table with Nemuri holding her fists in the air before passing out as well.

"And they're both down for the count. Sorry this happened Mr. Kamui Woods."

"It's not your fault. I should've figured this had something to do with their petty rivalry from the start. If anyone is to blame outside of them for this, it's me for condoning it to start." He started lifting up Mt. Lady in his arms while paying for the meal as I lugged Nemuri on my back. "Are you alright though kid? You did drink a lot tonight."

"I'll be fine. Hard to explain, but I couldn't get drunk." We walked out with Kamui Woods walking towards a motel nearby.

"I'm gonna go check in and hopefully get Yuu to sleep off some of the alcohol as well as help me rest up before driving us back home. You want to head there as well?"

"Nah. I have my own means of transportation." I opened up a basic portal Spell Sona taught me to be near the UA campus.

"Wait. Did you just use magic?"

"...Yes."

He took a deep breath before replying. "Ok. I'm going to pretend I never saw that and that we all had a little too much to drink to hallucinate. If my hunch is right from what the Angels said about the species I think you are, I think it might be best to try and avoid causing problems with you."

"Noted. Anyway, it was a nice dinner if anything."

"Thanks." The two left for me and Nemuri to enter the portal to wind up in front of my teacher's home. For some reason, the teachers had their own personal homes on campus with them looking rather nice.

"Alright. How do I get in?" Thinking about it, I started to tap Nemuri's face a bit to get her to wake up for a moment. "Hey Nemuri? Where are your keys to your home?"

"Mmmnn. Under the...*yawn* floor mat....spare."

"Floor mat, huh." I reached under to find a key to the small lodge. I unlocked the door and began walking in with Nemuri still passed out on my back. Wanting to make sure she drank something, I placed her on the couch and began going into the kitchen. 'Let's see. Maybe I should use a little magic to help with hangovers. No. Not yet. She needs to sleep most of it off and have some water in her.'

I looked for cups for water before having someone wrap around my body. "Izuuu. Why are you leaving me alone? It hurts my feelings."

"S-sorry Nemuri. I was just making sure you drank something beforrrrrowww!" I shrieked a bit while feeling her stroke my tails a bit.

"Don't lie to me Izu. You know I'm not young from what you know. But I'm also not afraid to show some things I have that the girls don't." She went right towards my ear to whisper into it rather seductively. "I can give you an experience you'll never forget~." I started to topple over with Nemuri moving herself to straddle on top of me with her butt sitting on my lower abdomen.

'Don't get hard. Don't get hard. Don't get hard.' She looked behind me to see my crotch and started to smirk. 'DAMN MY CAT INSTINCT!'

3rd person POV:

"Looks like somebody is a little excited. How about I give you a little more enjoyment~?" Nemuri began to pull her dress up slowly to show her jet black thong fitting rather snug on her lower half with the front half hardly covering her pussy. As she moved it farther up to her head, her curvaceous waist was shown to emphasize her hourglass figure before getting to a strapless jet black bra that hardly held her breasts in showing off a rather vibrant pink peeking out from the top part of the fabric.

"N-Nemuri, we shouldn't do this. You're my-"

"Shhhh." Nemuri placed her finger on Izuku's lips while leaning down towards his face. "As a teacher, I must know you are doing the proper things to please your women. Also, you can't deny that you're wishing this to happen as well." She moved her hand into Izuku's pants to rub his dick to try and put it at full mass. Feeling some of his length, the R rated hero smirked to bring her hand out and move to unbutton and unzip his pants to pull Izuku's dick out. "I'm amazed that such a glorious thing is in your hands. If I had known such a cute kitty such as you had this in his pants, I'd have taken Katsumi up on her offer to join the harem at the beginning."

"Wait, Kaachan asked you to join the hare-mmph!" Nemuri moved to have her ass sit on top of Izuku with her pussy directly in front of his mouth.

"If you are going to work your mouth, then I suggest tasting the sweet nectar of your teacher while she evaluates you." Nemuri turned her attention back to Izuku's dick to begin licking the tip and moving her mouth down his length to soak the sides with her saliva. When she got to the base, the pro moved her tongue up the back of Izuku's length slowly to have him concentrate on how it felt.

'Dammit. This is getting too much.' Unable to take it anymore, Izuku moved Nemuri's panties to the side to see her bare pussy dripping in front of him.

"You like it? I freshly waxed the other day."

Losing to his lust, the cat boy sticks his tongue into Nemuri's insides to slither around and taste her. His tongue's rough edges scraped around for the dark haired pro to clench her legs together and trap Izuku between her thighs. 'The taste of a woman. God I've not had a hard fuck for a while and this is making me go crazy.' Due to watching Usagi, Izuku hasn't been able to sleep with any of his girlfriends to add to the frustration he's had for the past week. 'I can't take it anymore!' As Nemuri was wrapped around Izuku's tip, he thrusted inside her mouth to send himself down her throat. She gagged for a second before feeling Izuku's claws latch into her ass to make her quiver in both pleasure and slight pain. Izuku felt his lower half wrapped in her soft embrace to thrust a bit faster inside her mouth while lapping up all her juices that came out. Eventually though, the feeling had become too much for Izuku for his hips to move faster with his head starting to throb. He was about to knot before having Nemuri pull off him.

"Naughty Izuku. Trying to cum where you shouldn't." She unlatched his claws from her ass and positioned herself to have Izuku's tip kiss her entrance. "Now it's time for true mating practice." She moved her hips slightly for her juices to flow down on Izuku's dick with the pause agonizing to the cat boy. His body was prepared for the initial act, however, he was denied intentionally as a form of torture by the pro. "I'm told that you can go into a blind lust rage. I want to see what that's like. Show me how hormone driven you can be Izuku and take me~"

'Crap. Rational mind...shutting down.' Izuku began losing his mind to grab Nemuri and shove her onto the ground.

"Ouch. That hurt-" She stopped when she saw Izuku looking at her like a predator to prey. He moved his body to trap her under him while tearing off her bra to show the R rated hero's enormous breasts. "Oh my, so rough~." He moved his member to align with her entrance before slamming inside and breaking through her hymen. "Ah!" Izuku placed a magic seal on her abdomen before continuing for her body to calm itself from the pain as he continued to thrust inside. Nemuri's body shook with each thrust as her breasts began to bounce in unison with Izuku grabbing a hold and biting on her right erect nipple "NNGH! You really know how to work a woman, don't you Izuku?"

Moving up to her mouth, Izuku began kissing Nemuri with inserting his tongue into her mouth to make her shiver from the feel of his feline tongue lapping up her insides. He pulled away shortly after to move himself to be directly behind Nemuri before continuing to thrust while fondling her breasts. His tails held her leg up with the R rated hero clamping down on his member and smothering it in her fluids to make the sound of skin slapping against one another more potent. "That's it Izuku. Give me everything. Fuck my naughty little pussy and satisfy yourself." She turned to kiss him again with the feeling of Izuku's thrust becoming more ragged. His dick started to swell up for Nemuri to know where this was going. "Cwub! Cwub ib mwa pwushy!" Her voice was stifled by Izuku's tongue as he moved faster before stopping for a moment to slam his entire dick inside and force his knot into her entrance before cumming deep inside her. Nemuri screamed in delight feeling her insides be soaked in Izuku's hot fluids to smile. The satisfaction was short lived as Izuku moved her to her stomach and the feeling of the cold kitchen floor made her body shiver a bit.

"What are you doing noOOAAAAHHHH!!!" Izuku pulled his knot out with most of the pain being avoided due to his magic circle. His dick laid between her ass cheeks being rubbed by her soft ass.

"Starting now, you're my woman. You got me?" Instinctively speaking, Izuku aligned himself back with her pussy as a mix of blood and semen was leaking out before slamming back in to force Nemuri to scram. "Say it! Who do you belong to!?" Izuku thrusted inside with using his tail to smack Nemuri's ass as his hands held her arms down. "I can't hear you!" He smacked her ass one more time for Nemuri to shout for pain and pleasure to be heard.

"Y-you..."

Izuku slammed into her again with his tails slapping her ass. "I couldn't catch that. Who do you belong to!?"

Nemuri's tongue came out as she smiled for joy at what she felt. "YOU! I BELONG TO YOU IZUKU! ONLY YOU CAN FUCK ME LIKE THIS! NOW GO AS DEEP AS POSSIBLE AND LET YOUR HOT CUM FERTILIZE ME TO MAKE ME YOUR SLUTTY PREGNANT WIFE!"

"That's what I enjoy hearing. Now get ready, I'm about to knot again." He sped up faster for Nemuri to hold onto what she could as her ass felt like it was being smacked by Izuku's pelvis. With one final thrust, Izuku came inside Nemuri again for her to force her eyes to roll back and drool to run down her mouth. For a solid minute, he came deep into her before forcing his knot out and moving to the front of the pro. "Clean it." She agreed for cum to drip out of Nemuri's pussy while she handled the remaining semen on Izuku's dick.

The next day, Izuku POV:

"Forgive me!" I knelt down with my hands and knees on the floor with Nemuri, Kaachan and Ochako sitting on the common space sofa. "I did the worst thing I could do to our teacher and cheated on the two of you! Please forgive me!"

"Relax, I planned for this to happen." Kaachan relaxed a bit with all of us looking at her. "What? I said she had the green light to join the harem. Though there is one thing I'm not happy with." She got up and went right towards my crotch to stroke it. "This thing probably knocked up our teacher going in bareback. You're gonna make things right with me and Ochako tonight, got it?"

"Wait, what do you mean?" Ochako stood up curious as a smirk came on Kaachan's face.

"Deku here is gonna make us mommies when everything's said and done. Get ready to have that fat ass of yours beet red when we're fucking."

Ochako stared blankly at Kaachan as her way to work through the issue was presented. 'Well I guess Eri and Usagi are getting little siblings soon. I wonder how this'll lead up to that?' 

And that finishes this chapter. See how this mistake shows it's head to Izuku next time. Hope you all enjoyed and thanks for reading.
