'Oh I really hope it isn't too late!' Walking down the UA hallway at a fast pace Midoriya Izuku was heading towards his teacher Midnight's classroom.

It was currently after hours and it was already night outside. His teacher Eraserhead was gone and most of the faculty is already home. Midnight almost always stays late grading papers so here's hoping she's still here!

"Ms. Midnight! Are you-" The broccoli boy's breath hitched and froze on the sight he just walked in on.

Sitting on her desk was his teacher Midnight. The one problem is that she was masturbating. Not only was she pleasuring herself but she was stroking up and down a penis that she had.

Izuku stood at the entryway of the classroom frozen. What was he going to do?! He was hoping that she wouldn't notice.

He wanted to leave but at the sametime he was looking at her in awe. This is the first time he's ever seen something like this in person.

This was way different than the internet!

Midoriya watched as she pumped her hand up and down her cock, her two balls doing a small jiggle after each stroke.

If he was being honest with himself it was a real turn on.

Wait.

No! No! No!

'Get those thoughts out of your head you pervert! What are you Mineta?' A funny thought came to his mind. 'Actually I wonder how Mineta would feel if he found out his favorite female hero had a penis.'

"Midoriya?"

His green eyes went bloodshot. Was his name just called?

"I thoight I heard someone mumbling, Midoriya what are you doing here?"

'You idiot you were mumbling instead of thinking in your head!'

He's rapidly moving his hands in front of his face now to cover up his embarrassment. "I'm sorry, sorry, sorry! I didn't see anything! Um uh, yeah!" He turned to sprint down the hallway and try and escape.

His vision started to get clouded by a familiar purple mist. He could faintly hear his teacher in the background before he finally blacked out onto the floor.

What have you gotten yourself into this time?

Izuku slowly opened his eyes to find that he was inside Midnight's classroom again. When he tried to move his arms to stretch from his slumber he found himself restrained.

He was about to charge One For All to break from his captivity when-

"Don't you dare think about what your about to do Midoriya. I don't feel like replacing a whip right now."

Oh so that's what he's currently tied to right now.

"So Midoriya it's seems like we have a problem on our hands."

When Izuku looked up at her she was looking at him with a glare that he's never seen her wear before. He could only look back at her in fear of what was going to happen to him.

He gulped.

"You have only been out for about ten minutes so don't worry about that. What you should be worried about is what you saw when you walked in earlier. Now, what did you see?"

"I, I, um..."

Her eyebrow raised at his stuttering words.

Izuku let out a deep sigh in defeat. Honesty was the best policy right? "I saw everything. I'm sorry Ms. Midnight!" He bowed from his restraints. "I promise I won't tell anyone please don't punish me!"

" I see. Well I can't exactly punish you for walking into a classroom, I'm technically at fault for reliving myself inside the school so you don't have to worry about that."

The green haired boy let out a sigh in relief.

"However, you are now the only person that I know of besides my doctor that knows I have a penis. So congratulations on that, so what are you going to do now with this information?"

"L-Like I said earlier I'm not going to tell anyone! I promise!"

"Okay Midoriya, I believe you."

"Thank you sensei..."

"I have another question for you now."

"Okay."

"Did you find what I was doing attractive?" She said with a now sultry voice.

"Um, uhh-"

"Because if I remember correctly, when I dragged that muscled body of yours into this classroom while you were passed out I noticed a very specific development in the area beneath your waist."

"Oh, well, uh I... umm-"

"Come on Midoriya be honest with me~"

"Okay, yes I thought it was really hot..."

"Hot you say? Did you find it hot the way I jerked my cock slowly on that desk? The way I took deep breaths as pleased myself."

The blush creeping on his face was now extremely noticeable. Izuku felt himself getting hard again from his teachers sultry and erotic words.

"Are you into futanari Midoriya? Because that's what I am, everything seems possible in this world of quirks."

"Yes, I'm into futa Ms. Midnight..."

"Fufu~ that's what I wanted to hear. Say Midoriya I always thought you were pretty cute." She stood up off her desk and walked over to him still sitting on the floor.

She bent down and put her hand on this cheek. "How about we do some extra curriculum training Midoriya. Would you like too?"

Izuku may be dense but was she suggesting what he thinks she's suggesting? "Yes, I-I would like too..."

"Then we are in agreeance fufu~ I'm going to have so much fun with you."

The U.A student then felt his lips on hers as she came into a passionate kiss with him. Her two hands on each side of his cheek as she progressively tried make out with him. He flinched when she finally tried to force her tongue into his mouth, he fully welcomed her.

A full minute passed as he sat on the floor as him and his teacher swapped tongues and saliva. Izuku still couldn't move from his restraints so he could embrace her himself so he tried the best he could with only his lips and tongue.

Then he felt Midnight take her tongue out of his mouth as she stood up again. "Mhmm yes, that was very satisfying Midoriya, good job."

"Thank you I tried my best." He said.

"You always do Midoriya."

"Thank you Ms. Midnight."

The R-rated hero looked down to her bound student, she smugly smiled as she noticed a formidable tent that has arisen in his uniforms pants. "Oh what do we have here?" She took her right boot and nudged his staff.

Midoriya let out a small moan as his teacher slowly moved his prick around through his pants with her high boot. She had that sultry smile on her face as she kept teasing him through his trousers.

"Your so hard Midoriya. I feel so flattered to have you as my student." She walked forward to him until her crotch area was now right near his face. "Are you ready for this Midoriya?"

He knew what was about to happen, there is no going back now. "A hero is always ready Midnight."

She giggled as she grabbed ahold of her costume zipper. "As they should be."

Izuku stared as she whipped her hard cock out in front of his face. The deep crimson on his face now deeper. He could feel the heat of her shaft that was so close to his forehead.

He took a small whiff as she nudged just a little bit closer. The evident smell of feminine soaps and other products keeping it from having any off putting odors.

He started with her tip, the first small lick of his first time tasting cock. Licking all around her crowned top. Before properly putting his lips around the full tip of her penis.

Midnight bit down on her lips as her student was sucking her off. "Yes, very good so far Midoriya." She reached her right hand behind his green curls and started pushing him a little bit more down.

Izuku opened his jaw a little more as he slowly took more and more of her length into his mouth. He was still using his tongue to swirl around her girth as she kept pushing in.

Her cock kept pushing father into his mouth before he realized his gag reflex was going to kick in soon. Noticing that she was about to go into uncharted territory Midnight stopped herself.

"Now Midoriya I'm going to stick it into your throat. Just try and take it steady, breath through your nose, and try not to gag too much okay?" She heard a small groan from him as a response. "Alright I'm going to take that as "your ready" okay?"

She now pushed into his mouth as far as she could really slowly. Looking at her student she saw how he struggled to not pull back from her. "Take it easy and breathe through your nose." She saw him relax a bit. "Very good Midoriya. Now for this."

The hero proceeded to pull back a bit before shoving it back slowly into his mouth before doing it again, and again, picking up the pace. She put both her hands behind his head as she face fucked him and his throat.

Now gaining confidence in himself to do something besides just sitting down Izuku started bobbing his head back and forth in rhythm with her cock. Now looking up at her with his bright green eyes for approval for trying to increase his blow job skills.

Seeing that he wanted her attention for himself taking action she patted his head ruffled his cute green hair. "Your such a good boy Midoriya. Keep up the good work!"

Pulling put her dick again fully this time she rested her testicles above his mouth. "Make sure you get these also, these two babies are really important!"

Nodding, Midoriya then slathered his tongue over her two swollen balls making sure to get everywhere he can before she pulls back again.

Two minutes later...

She was getting rougher and rougher as the time passed. Her intoxicating scent and the taste of her throbbing cock was making him dizzy. He honestly loved this, Izuku never felt something like this before.

"I'm going to cum down that cute little throat of yours Midoriya. Prepare yourself I've been edging before you came earlier it's going to be huge."

Swallowing in preparation he readied himself for her supposed "huge load" she was going to shoot out.

And huge it was indeed. He felt the warm rush of her semen now traversing down his gullet. It's unique and warm taste now filling his whole mouth, swallowing it as best as he could.

Noticing that he was struggling to get it all down Midnight pulled her cock out entirely and sprayed a few more of her hot loads onto his freckled face. Her hot spunk now covering his cheeks, nose, and forehead.

Midoriya and Midoriya took a couple deep breaths to collect themselves.

"You did a wonderful job Midoriya! And look at that cute face covered in my baby batter, wish I could take a picture!"

Izuku took another deep breath. "Thank you Ms. Midnight I tried my best for you."

"Mhmm, and you gave your best indeed." She had a new grin on her face. "We are not done just yet!"

"What do you mean?"

"Oh Midoriya, you think I'm going to let that cute little bottom of yours go so soon?"

He flinched a little as his teacher grabbed ahold of him and gently planted him face first onto the floor, his ass sticking up into the air. "Look at this fine bottom Midoriya. You and the rest of your class have been training these bodies really well."

The U.A felt the grip of his pants around his waist loosen as his teacher slowly started to pull them all the way down. His two cheeks and cock now dangling forth im front of her.

"Oh this is so cute! You even have those cute freckles on your behind!" She gave on of them a soft spank and a kiss right after. "Such firm and tight glutes you have here. I'm going to have so much with them."

Getting a little smile on his face he asked. "How much fun?"

Opening the crack between his cheeks showing his pucker. "Oh lots Midoriya, lots."

He felt electricity shoot up his spine as he felt Midnight kiss his asshole. She then proceeded to lick and kiss around his rim. He felt her soft hand now grasp around his hanging cock and jerk him off.

She was milking him as her tongue was now penetraing through his shitter. Small moans were escaping his mouth as all of this transpired.

"Ms. Midnight t-this feels really good."

"I'm glad, just trying to find your little prostate now." Pulling put her tongue she then took her index finger and started pushing it inside. "It's so tight just trying to wiggle my little finger in there."

"Ah~ Mhmm!~" Izuku blushed up a small storm on his face as he closed his mouth immediately from those noises coming out.

"Found it!" His teacher declared as she now was wiggling her finger in his sensitive area as she resumed to tug on his penis. She was finding great joy of hearing his cute moans coming from his mouth.

"Ms. Midnight I feel s-something coming!"

"Oh, we can't have that now can we?" She took her finger put of his anus and stopped jerking him, stopping him from getting close to cumming himself.

"I was so close? Why did you stop?!"

"I want to save your graceful ejaculation until the end sweetie~"

He pouted her response to his question.

"Now it's time for the main event Midoriya. I've been preparing and lubing you up pretty good so it won't "hurt" as much as it should for the first time okay?"

Her cock, now hard as it used to be was now lined up as his back entrance ready for penetraing. "Are you ready Midoriya?"

"As any hero should be."

"That's the spirit!" She pushed right into his ass pussy in full force. The inside of him was extremely tight, even harder then it was when she was putting her finger into him. "Oh, Midoriya you have no idea how good this feels! How tight you are!"

The only reply she got from him from her compliments was his now audible and adorable moans.

She pulled out and pushed back into him again, a wet spurting sound now making its way as she continued to fuck him. Her cock was now going faster as she was now losing herself to the pleasure of her own student's sex.

Fucking him faster and faster without stopping she picked him up off the ground finally and held him by behind his knees as clinged onto him in the air. His own cock now bouncing up and down from the sheer force of her pounding.

Minutes would go by as the two of them had sex in several spots and positions around the room. From having him sit on her lap to having himself bouncing up and down as she laid on the floor.

Now out of his bindings he was laying on a desk as one leg was over her shoulder and he was laying sideways. The two looked at each other loving as two of them continued to pork each other.

Reaching his cock with his right hand Midoriya jacked himself off as Midnight continued to fuck him silly. "Ms. Mi-Midnight I'm getting close!"

"Me too Midoriya! Just a couple more seconds I'm so close!"

The two of them moaned in ecstasy as they both came at the same time. Izuku felt his bottom filled with his teacher's love and he finally got the satisfaction of cumming on his own. His load sprayed onto his uniform and the which ever poor student's desk his was on top of.

The two of them laid there together in afterglow. The U.A student felt the semen slowly coming out his now loose backside. "Ms. Midnight that was amazing."

"Yes it was, you were a terrific fuck Midoriya." He blushed at her words. "You've been calling my "Ms. Midnight" all evening, when the two of us are in private just call me Ms. Kayama or Nemuri okay?"

"Yes Ms. Kayama."

"Good then." She placed a small kiss on his forehead. "Now get all of this cleaned up, and maybe next time I'll let you top."

He nodded.

"But just keep this between us. Let this be put little secret~"

Next day in class everyone was busy with their school work. Class-1A now in Midnight's class for the next hour sat around in silence and small chatter as they continued their assignments.

Sitting at her desk Midnight sat with a blank face as she graded papers from her other classes.

Her work was interrupted by a student tapping on her desk.

"Oh! Uraraka, what do you need?"

"Nothing Ms. Midnight, I was just wondering if you knew where Deku-kun is? He left earlier but he still hasn't come back."

"I think he had a meeting with other teacher, no need to worry about it."

"Thank you." The gravity girl walked away back to her desk, oblivious to where her friend really was.

Midnight had a small grin on her face as she looked down under her desk. There was Izuku being a good student and keeping his teacher relaxed while she did her work by choking on her cock for the hour.

"Yes, no need to worry indeed."
