'What's wrong with me? Why do I feel like my body's ripping at the seams?' I began feeling my body go on fire with it feeling like I could break apart at any moment. 'What's making my body like this?' I glanced up to see Yaoyorozu and Uraraka going pale while eating. I took some notice to see them barely able to keep the food in their mouths to have the urge to stuff it full of my-'DUMBASS!' I slammed my head into the table while shouting in my head. 'DUMBASS! DUMBASS! DUMBASS!'

"Izuku. Are you ok?" I glanced up at Shinobu who was staring at me with worry.

"I-it's nothing." I glanced over to Mitsuri to see her stuff her face with a smile on her face. My gaze went down to her open uniform to feel my mouth salvitate a bit. 'So big. That uniform looks like it's barely fitting her body and is going to pop out at the sec-WHAT THE HELL AM I THINKING!?'

"Izuku. You need to try this. It's so good." Mitsuri smiled before pushing some food held in her chopsticks towards me. "Say ahh~" I went red before opening my mouth and having her push it in my mouth. As it was in my mouth, I could taste Mitsuri on the chopsticks have the urge to taste her mouth directly.

'It's so sweet. If I could push forward right now, I could take her lips and force my tongue down her throat. Grab ahold of her chest through her uniform and slide my free hand down and dig my fingers into her-STOP THAT!' I couldn't take the feeling of what was going on in my mind right now to stand up. "S-sorry, Shinobu. I-I'm just not that hungry tonight."

"Oh. No worries. I'll have it put in the fridge in case you get hungry later tonight. Would you like anything else or will you retire to your room tonight?"

"I think I'll call it an early night. It's been a while since I've had a night where I called it in at a normal time and slept through." I tried to walk away somewhat fast to avoid someone seeing me before turning a corner and looking down at myself. 'Just keep it together. Nobody saw you, so you can handle this and then go to bed.' I walked right to my room before bumping into Kanao who was pulling some laundry. "Sorry." I tried to help with her gaze looking down at my lower half. I went red with this and run away. "I SWEAR THIS ISN'T WHAT IT LOOKS LIKE!" I went right into my room and pulled the covers over me to hide my shame. "Why is this happening to me?"

Izuku laid in his bed uneasy with everything that had happened. His body continued to feel extreme tension to the point he's been handling it himself for a few times now to feel no satisfaction at all. 'Dammit! Why is this happening?' He began crying a notable amount before holding his head under his pillow. 'I want to die right now.'

"Izuku~" Hearing a bit of noise, Izuku moved his head up to see Mitsuri crawling on top of him. "It's been a while since I've seen you. I thought maybe a little bit of skin ship could be worthwhile~" His body was completely under hers as Mitsuri moved closer to Izuku's lips. "If anything, could I at least have one little late night kiss~ I promise I'll leave after that."

As she said this, something in Izuku finally snapped and had him smile. "Really. Is that all you'd be willing to have tonight?" This confused Mitsuri as her arms were grabbed by Izuku as he flipped her to be under him. She looked up at him to see his eyes be that of his demon half. "How many years have you've shoved your chest in me or tried to show me your feelings? I think it's about time I try to reciprocate them."

Izuku moved his head down to Mitsuri's neck to begin kissing it and sucking on her skin. The sudden act shocked the pink haired woman as Izuku was showing a side she's never seen of him before. "I-Izuku. What's gotten into you? You're acting weird." He moved his head to be face to face with her to show the flushed red on his cheeks before kissing her mouth. His tongue swirled inside as Mitsuri's strength slowly depleted to the point she accepted his actions. As such, Izuku's hands pulled off Mitsuri's wrists and caressed her chest. He slid them inside to pull Mitsuri's breasts out and grasp them in one firm motion to shock her and make her shriek a bit.

Pulling away, a trail of saliva connected the two as both looked notably dazed by the act. "You're right, Mitsuri. Something has gotten into me. I found out just how sexy you are and how I'm wasting so much of your enjoyment not doing anything. So why don't I try and pay you back for that." He leaned down and whispered the last bit in her ear before biting the tip to make Mitsuri shriek. She then felt the sash on her robe come undone to look down and see Izuku pulling the robe to the side and revealing her white T string. He smiled and went down towards her breasts.

"Izuku. It's embarrassing. Don't be so rash." Glancing at the bright pink while also seeing her nipples hiding inside her breasts, Izuku began sucking on Mitsuri's nipples to bring them out to the surface. This forced her to grind up on him and hold his back. Mitsuri felt the sweat on Izuku to look at him and see he seemed to be struggling a notable amount. "Izuku. You don't have to worry so much. I'll accept everything you are as you're willing to accept everything I am." Mitsuri placed a hand on his cheek and smiled. "I promise I won't leave you."

Hearing this, Izuku began to lose his primal senses to return to his normal self a bit. "Mitsuri. I'm sorry." He wrapped her in a hug and began holding her close. "I almost did something terrible to you. I don't deserve you." Hearing this, the pink haired woman wrapped her arms around Izuku and held him close to her.

"If this is about the new moon. Don't worry. I'm always here for you and I always will. I chose you for my husband." Hearing this, Izuku let Mitsuri position herself a little better so she was laying her head on the pillow with her robe off, leaving her in her underwear. As this happened, Izuku pulled his shirt off as well as his pants to leave him in his boxers. The two kissed with Izuku's hand going down to Mitsuri's crotch and rubbing his middle and ring finger across the entrance. This had allowed a moan to be stifled by Mitsuri before her hand went towards Izuku's boxers. She pulled the elastic a bit down to feel Izuku's member hardening and stroked it. This had given her a view of Izuku's pained expression to make her smile a bit. 'So adorable.'

Taking the initiative, Mitsuri pushed Izuku to lay on his back before crawling over to his erect dick. Looking at it, she began running her tongue from the tip down towards the base, holding it particularly long over the glands before bringing her head up back to the tip and placing it in her mouth. Her tongue swirled around with Izuku's mind floating away from the sensation. In his daze, the green haired boy's sights were set above him as he watched Mitsuri's ass sway back and forth to grab a hold of it. This forced her to yelp a bit before feeling Izuku move her thong to the side. "So this is what you look like down here." Seeing her pussy drip love juice as well as a notable pink patch of short hair, Izuku began to smile. "I think it's time I return the favor. Don't you think." Izuku stuck his tongue out to lick Mitsuri's slit for her to shake in excitement.

"Izuku. Not so suddenly like that. You're going to make meAAHH!" She was cut shut by Izuku sticking his tongue into her entrance . His tongue swirled around her inner folds, forcing Mitsuri to shake and start losing strength in her legs. As she was about to fall down, she looked back at Izuku's dick and started to deep throat him. The tip began getting wrapped in Mitsuri's throat as she continued to moan. The vibrations forced Izuku to buck his hips and force Mitsuri to hold on and take Izuku as deep as she could. The two continued this for a few more minutes before Izuku pulled away first.

"Mitsuri. I'm gonna cum."

"Dwo iwt." She spoke with Izuku's member still in her mouth for him to give a few more drastic thrusts upwards. On the final thrust, Izuku came down Mitsuri's throat with her body responding and cumming over Izuku's face for him to try and drink it all. Once they finished, Mitsuri pulled away with some semen still in her mouth to open it up and show Izuku the contents before swallowing it. "Ahhn. So sweet."

"Mitsuri." Seeing her do this forced Izuku's mind to go for a loop again and push himself into a kiss with her. Mitsuri fell back and laid on the ground with Izuku's dick positioned on her stomach still hard. "I...I want to...do it"

Mitsuri smiled while pulling her thong off and placing it to the side. She reached up to offer an embrace to Izuku for him to hug her back. Once ready, he adjusted himself to hold his tip at her entrance to look at her. Mitsuri nodded for the green haired boy to begin pushing inside her. Mitsuri felt her insides be pushed open to feel some discomfort, but easily fixable. As a way to help, she started counting Izuku's inches before getting to 10 and feeling his hips hit her thighs. Looking down, Mitsuri could only smile as she felt her body embraced by Izuku. "We're one~"

"Yeah. Your insides feel really good. I feel like I might lose it any second now." Izuku began moving slowly to avoid Mitsuri feeling any pain with her moving up to kiss Izuku's lips. She pushed her tongue into his mouth for Izuku's mind to continue with the sensations to pick up speed and push deep into Mitsuri. As he did, her inner folds wrapped around and slid around Izuku's member, forcing her body to have all her best spots hit. Her voice began to speak up through muffled moans into Izuku's mouth as she pushed her breasts into Izuku's chest to have him feel her erect nipples slide over his chest before having one hand go to her large ass and holding it tight. Mitsuri took note of this to feel Izuku's thrusts become far more aggressive. Her insides could tell his body was heating up and wanting release.

"Ishukhu. I wove wou~" Mitsuri spoke through their kiss as her hips tried to move on their own with Izuku practically smacking into Mitsuri.

Minutes went by with both holding onto one another as close as possible before Izuku tried to speak up. "Gwonna cwum." He tried to speak with Mitsuri not letting his mouth go from their kiss. She locked her legs around Izuku for him to understand she won't let go of him.

"Winshide. I whant it winshide mwe," Izuku understood to hold Mitsuri's hips as he bucked his hips notably faster inside her until finally giving one last thrust upwards and dropping his seed deep in Mitsuri's inner walls. She moaned out as her body shook violently from the sensations. As they finished, Izuku laid Mitsuri down and pulled out to have one last shot come out and hit her belly. "Mnnn. So good~ I love this feeling of being full, Izuku."

"Who said we're done?" Izuku glared at Mitsuri with his demonic eyes as his dick stood straight up. "Now you're going to pay me back for all your acts. I hope your skills allow you to hang in there with me." Mitsuri smiled a bit while being glared at like a piece of meat waiting to be dug into.

'Uh oh. Mitsuri's in trouble.' "Izuku. I think you should calm down a littl-KYA!" Her offer rested on deaf ears as the two continued throughout the night with everyone in the Butterfly Mansion hearing the sounds to be kept up. Those that knew what it was were left with a mental picture in their heads while those that did not were thinking it was some kind of training.

After my little...night with Mitsuri, Shinobu had both of us kneel in front of her in her office looking somewhat tired and angry through her smile. "It seems you two have taken it to believe that this home is no different than a love hotel. Granted, it was partially my fault Izuku was in this state for not knowing he was in need of an increase on his dosage. But that does not mean you sneaking into his bed and allowing him to do things I'd rather not talk about to require you to take medicine to ensure you do not get pregnant is not something in my responsibility."

"Yes. I'm sorry, ma'am." I held my head down as Shinobu pulled out a vial and injected it in me with little concern if it hurts. "Ow."

"This may be more than what you should get, but it will prevent another Mitsuri incident to happen." She turned to Mitsuri and explained what exactly happens to me during a new moon for her to now understand the full story.

"So he can get very horny during the new moon?"

"Exactly. I'm not saying Izuku did not find you attractive before, but this was more of a problem because of the new moon. Try not to let him go on a rampage like this again please."

Immediately, Mitsuri had an idea to have stars in her eyes. "Can we wait next time until after the new moon for-"

"No. Not happening." Shinobu stopped this in it's tracks to turn and begin doing her work. All I could say from the act though is that now I'm in the dog house and all I can do is let this happen.

'She's mad now. I just hope this doesn't last long.'

And that finishes this chapter. See what happens next time with the group returning to UA. Hope you all enjoyed and thanks for reading.
