Ok to remind you all, I had Izuku as an Alpha in the start of this. This chapter will dive into the omegaverse a bit with a certain frog girl going into Omega heat(do not ask since it will be a large explanation that you'd be better off to look up. Just be mindful that this is a unique type of universe). Enjoy.

Izuku POV:

"Shouto, can you pass me the extract?" "Right here." "Thanks." After the incident of last nights fight, things were a little quiet for the time being. At least as quiet as I can get out of my life. Right now, I'm in the kitchen with Shouto making sweets for everyone since I was in a good mood. "Base tastes good, now lets cut the bread." I grabbed two knives with my tails and began to cut the stale bread we had. "How skilled are you with those tails?" "Let's just say, I never miss tail day." I try and flex a little to earn a bit of a snort from her. "It's nice to see you happy. You seemed very down after the USJ and haven't been able to fully recover from it." I stop cutting for a moment as she said this.

"I'm still haunted by what I failed to do before, but I'm done living with what I should've done. I can't keep living like that. If I do, it'll only hurt the people I love and care for around me." Shouto came over to hug me after hearing this. "Your a good person Izuku, don't let anyone tell you otherwise." I smile at this moment a bit remembering how many people really care for me. "I should probably finish this. Koneko said she was coming over to hang out with us and she's a huge sweet fan." "Yeah, but make sure that you don't do it all by yourself. That's why I'm here." I began to purr at this to make a large smile grow on Shouto's face.

As we finished up, Mina walked in looking at us worried. "Hey Mina, what's wrong?" "Tsu seems a little off today." "What do you mean by 'off'?" "She hasn't come out of her room today. When I went to see her, she looked like she was toppled over in pain." I think on this before grabbing a bit of water and making a small bit of tea that helps with soreness. "I'm gonna go check on her. Mina, Shouto, you two mind watching the bread pudding that's in the oven?" "That shouldn't be a problem." "Aye aye captain!" Mina started to salute me for us to laugh a little. With this said, I made my way up to Tsu's room.

Once I was on the floor, I noticed a strange smell. It wasn't bad, but it was strong and heated up my base instincts. 'Something smells really good.' As I got closer to the door, the smell got stronger and stronger. "Tsu, you ok?" I knocked on the door to hear groaning and whimpering inside. "Tsu,I have some tea if you want. It should help with aches and pains a bit." "Nnnnnmmm."I heard her walk to the door before opening it enough to put her hand out. She grabbed the tea slowly to bring it back into the room. I hear her practically chug it before the door opens again to have her place the cup on the ground. 'Ok, this is strange.'

I sit near the door to try and talk to her. "Hey Tsu, what's in pain?" "....I just feel really restless to a point it hurts." I sigh at this before I ask her the next question. "How far does your animal quirk bring you between the line of frog and human?" "...Kinda far." "*sigh*....Your an Omega, aren't you." Silence was between us before she answered. "Yes." "Your suffering from Omega heat right now, aren't you?" "I took medicine for it, but the symptoms already started. I wasn't sure how people would react with my condition, so I stayed in my room. I didn't intend to worry anyone." "Animal instincts are a bitch sometimes, huh?" "...A little." We laughed a little after I said this.

"So when was it that you first started your Omega heats?" "Two years ago. My mom helped me through it, but the medicine she gave me only lowers it to functioning levels. It doesn't do anything if your already in it immediately after as well, so I have to bare the pain until then." I kept silent while breathing in more of her pheromones that leaked under the door. "Tsu, you were there for me when my sister did what she did at the USJ and helped me deal with the aftermath. I want to repay you, but I don't think us talking nearly qualifies." "Tsu cracked the door a bit open to look at me. "Izuku, your an Alpha right?" "How do you-" "I smelled it on you the first day. But you don't act like one, why?" "I just don't see a point in forcing someone to do what they don't want to do. I didn't grow up learning to take what I want. I grew up to show compassion for others. That's why I'm talking to you, because I care for your well being."

Tsu shuts the door before unlatching a lock she had on. "If you want, you can come in." I stand up to walk in with the lights turned off. The smell of Tsu's pheromones were driving me wild inside. Every urge inside me was telling me to make her mine and mine alone. "Sorry if your uncomfortable." I turned to see Tsu's face completely red with baggy shorts and an over sized Shirt on practically covered in sweat. 'Dammit that smell is getting to me. Don't take advantage of her, she's not feeling well.' "Don't worry, it takes more than a little arousal to take me down." I smile at her while avoiding breathing in too much. "The first time this happened, my mother never left my side. She said that as an Omega, this would happen to me on occasion and gave me the medicine that subsided it. The problem is, it takes half a day to be in full effect." "So you gotta suffer like this until that happens." She nods and goes back to lay on the bed.

"When I first met you, you said you found my scent tasty. What did you mean by that?" "Sorry, I just didn't eat that much the first day. I kinda like the taste of frogs legs and spoke out of my stomach. Didn't mean anything by it." I sit down near the foot of the bed with Tsu staring at the ceiling. "Hey Izuku?" "Yeah?" "...What does sex feel like the first time?" "PFFFT!" "Sorry if it's a weird question." "N-no, it's just..." I try to find the words to explain how it isn't odd to ask with my head coming up with nothing. "Uhhh...ok it's weird. How should I put this? A first time is something that you should cherish. In the form of a man, their first isn't as precious as a woman's can be. To be honest, I can't answer you accurately since I had mine in a blacked out state when my instincts took over. I only came to after I'd already done it with Kaachan and ruined it for her. As she said, I didn't hold back and made it very painful. She knew it wasn't my fault and says she didn't take it to heart, but I felt horrible for her." I held my head down a bit. "I think Katsumi cares enough about you that she's happy it was at least you that did it to her." I pick my head up to see Tsu hug me.

"If it were me, the fact my first was with a person I love at the very least is enough. I'd accept that whether it was painful, gentle, or anything else. To me, that would be fine." "Tsu-" I turned my head to have her lips push on mine. Her hands started to clench my shirt as she moaned in my mouth. When she pulled away, Tsu gave me a look of desire before speaking. "Izuku, can you please help with my heat? I can't take it anymore." 'Wish I knew this before walking up here.'

3rd person POV:

Izuku began to pull up Tsu's shirt to reveal her bare ample chest. He started to nibble on the left niple while twisting the other with his right hand. Tsu began to moan at this feeling the sharpened canines of Izuku roll over her soft bud. As this went on, Izuku placed Tsu on her back and pulled her shorts off. As he did this, he noticed that she did not wear any underwear and was rather wet to begin with. "Commando I see. Meow~." Izuku smirked at this with Tsu slightly panting. "Please stop teasing me." "Oh, but this is only the beginning. Your going to see why cats are above frogs in the food chain." Izuku moved his head to Tsu's nether region to start licking her slit. The rough feeling of his tongue forced a shiver down her spine as the young cat boy's tongue slid up and down her. Izuku began to get a little daring though and bit slightly down on her clit. The act had made Tsu nearly scream if she was not mindful. Following this, Izuku rolled his tongue inside Tsu to taste her inner folds. Her breathing was staggering as the feel of the feline she came to care for found his way inside her to taste every part he could.

As his tongue kept scraping the insides of Tsu, Izuku began to feel the frog girl tense up to indicate she was close. Before she could however, Izuku pulled out of her to see tears in her eyes as she couldn't climax. "*ri...bbit*." "I think a certain Omega would rather something a little different." Izuku smirked as he began to pull his shorts down a bit to drop his dick on Tsu's face. She immediately grabbed it and began to suck him off as if she wanted nothing but what was in front of her now. Izuku felt absolute bliss when Tsu began to wrap him with her tongue and take him as deep as she could. He felt himself get close and began to move his hips himself. However, before he could finish, they heard a knock on the door.

"Yo Tsu, you ok in there?" Jiro had knocked on the door to force Tsu to take her mouth off of Izuku's dick to reply. "Y-yeah, I'm just a little under the weather." "Ouch, that's gotta suck." Tsu kept trying to talk to Jiro and get her to leave before hearing a small growl come from Izuku. "Izuku, what are you doing?" Tsu whispers this as Izuku grabs her to lift her up and over over his member. "Don't do it! I don't want Jiro to hear this!" Izuku smiled as he answered. "Starting now Tsu, your mine and only mine." He slams her down onto his member taking her first and nearly making her scream. She covers her mouth enough to keep it from coming out, but strangely felt no pain.

"Is everything ok in there?" "Y-yeah, just stepped on something." Tsu tried to hold back her shouts as Izuku pounded inside her with all his might. The feel of her thick body as Tsu bounced on Izuku made him jump off the rocker. "Tsu, I'm gonna knot." "Not while Jiro's outside!" "Is someone inside?" Jiro was about to walk in, but stopped when Tsu stated to her. "Everything's fine, just let me rest *ribbit*!" Hearing her shout this had Jiro confused, but put not a lot of thought in it thinking she was just sick. She walked away and down the steps right as Izuku pushed his knot in and came inside Tsu. "*RIBBIT*!" Tsu felt the warm liquid inside her as Izuku realized what happened.

"Oh my god, I'm so sorry Tsu! I didn't mean to finish inside!" "It's ok. The medicine works as a contraceptive as well. I won't get pregnant." Tsu laid down slowly enjoying the feel of hot semen inside her. But without warning, Izuku pulled his knot out to cause immense pain for her. "Izuku, what are you-" "Your mine now Tsu, that means I have to mark you as such." Izuku positioned his dick over her asshole to make Tsu perk up a bit. "Nobody will have you other than me. I'm going to take all of your firsts so no man can ever do this." In one thrust, he shoved all 12 inches inside Tsu to make her scream into her bed. Her large butt had began to giggle a bit with the constant thrusts inside it. While doing this, Izuku picked Tsu up to place her on his lap.

"Get used to this feeling Tsu, because this is going to be the feeling of the man you will be with forever. Starting now, your one of my women." Tsu couldn't understand, her mind was caught up in the feeling with her tongue dripping down to her pussy to lick the remnants of Izuku's sperm that was leaking out. His pace grew faster and faster as he neared his end. "Now Tsu, who's your Alpha mate?" Tsu heard this and answered. "Y-you are. Only Izuku can fuck me!" Izuku released into her ass to make Tsu start to spray her's and Izuku's fluids out of her pussy. As the semen from before dripped out, Izuku used this as a lubricant to pull out of Tsu's ass to make it less painful. He brought his dick up to her face to which she cleaned it before going back into her pussy. A few hours passed to completely cover Tsu and Izuku in their fluids with every one of her holes filled to the brim as they fell asleep with Izuku still erect inside her body and on top of her.

Few hours later, Koneko POV:

I walk into Heights Alliance with some of Izuku's classmates around playing games and talking among themselves. "Hey Koneko. How was school for you?" Ochako came over to me smiling as she normally does. "It was nice. Have you seen my brother?" "Sorry, but I haven't." "Same." Katsumi said this trying to think where he could've gone. "I asked him to go up to check on Tsu some time ago and didn't see him since." Mina said this with this girl with aux cords coming out of her hears going red. "You don't think he-" "Got laid? Possibly." Katsumi stated this with little reaction to the fact my brother may have had sex with her classmate. "Your fine with that?" "I told him were making him a harem. If he wants the frog girl, then he's got my approval to pound the frog until she's roadkill. All in the mighty name of Operation Dekuharem!" Katsumi shouted this with Mina, Ochako, and Nejire clapping. with a familiar smell I've discovered before making it's way into the common area.

Everyone was silent at this. "But she wasn't feeling good. Shouldn't he show some compassion?" "I can tell you right now Jiro, she's most likely in Omega heat instead of not feeling good." "What's Omega heat?" The guy with tape coming out of him called Sero asked this while stuffing his face with bread pudding that smelled awesome. "Omega heat is when Omegas in the animal kingdom go into a form of a heat cycle. They suffer similar aspects as if in heat while producing large amounts of pheromones to attract Alphas to breed with them. I could smell the pheromones from the moment I walked in and know that the effects of them are similar to feeling sick. Strangely enough, sex will help more than any medicine or something like that." "Huh, so it's like the old saying that doing it is good for your health?" "Exactly."

A blond idiot came up to me still confused and kinda excited. "So she needs some help huh? I'm willing to take one for the tea-" "As much as I'd love to see you try Jamming yay, you may die a painful death if you go up there right now." Jiro started to laugh at this while their human robot came over to ask why. "Do Omegas go into an agitated state or something when they are in heat?" He asks this with a karate chop motion. "No, but Alphas aren't too kind to others trying to take their mates from them, especially when it's an Omega. They'll literally fight to the death to claim their mate as their own. So unless you wanna try and fight my brother when he's serious, I'd sit back down and pretend that isn't happening right now."

The fool sat down with the bi colored hair girl Todoroki giving me a piece of bread pudding. "Izuku made it knowing you were coming. Came out really good." "Thank you." I took the piece and grabbed a little to try. My ears and tail shot out by the sweetness to be satisfied. 'Izuku, you do know how to make me happy.' "Good to know you and Deku aren't much different. Wanna play a game and talk about what you missed with your cute older brother." I nodded at Katsumi as her, Mina, Ochako, and Nejire sat around for us to learn about him and me a bit.

After some conversations, Izuku came down with the girl I believed was Tsu looking rather plain facial wise. "Midoriya! I highly recommend you limit your sexual acts to where they do not hinder other stude-" "Iida, please stop." Tsu says this as she holds onto Izuku to make him pat her head. He walks over to the kitchen to get a piece of bread pudding for him and the frog girl before sitting next to me. "Hey Koneko. Sorry I didn't get to greet you when you got here." "It's cool. I got to learn a little about you from the girls, so were even." He smiles at me as we both take a bite from our snacks to smile and wag our tails in unison. "Yeah, no argument their fucking related." "Agreed."

And that finishes the chapter folks. So the workplace study will be a little different with Izuku diving into the Kokabiel arc and another arc that you will learn inside it. During this, he'll get to know the members of the Gremory and Sitri house a little better and maybe gain someone along the way. Hope you all enjoyed and thanks for reading.
