"You should warn me, you know." Waking up on a Saturday and seeing those twirling ear jacks coupled with a cute monotone face isn't so bad. There sure are worse sights in the morning. Though perhaps her choice of talking points could have been better.

"Oh Miss Jirou, were you spying on us~?" Mina playfully arched her back toward the smaller girl, placing one hand over her own lips as well. "Like what you heard?" She raised both eyebrows and narrowed her eyes, maintaining a teasing tone.

"Like you could hide the sounds of your bed creaking." Jirou rubbed the back of her neck nervously. Although her words contained a sarcastic denotation, the reflexive gesture signaled an uncomfortable feeling. "Last night was…. Midoriya right?" She averted her gaze to the floor.

"Yep!" Mina giggled once she confirmed the punk rocker's suspicions. "Disappointed it wasn't a girl?" She put on some puppy dog eyes and leaned in, clearly still unserious.

"Don't you think he's too far?" A multilayered question from the punk rocker. Now that she crossed the line with Izuku, what prevented Mina from taking away her raven haired girlfriend? "Kinda messed up don't you think?"

The pinky aggressively recoiled at the line of questioning. Perhaps she had been blinded by the prospect of finally getting to see what her greatest curiosity would be like in bed. By ignoring all the negative aspects of this new twisted relationship she had formed, maybe she really was doing something detrimental. Though, the aching on her lower back pushed against this line of thinking.

"I'm helping him control his big thing." Mina fought the urge to squirm as she remembered the size she faced hours earlier. "Think of it like tutoring a friend for a huge test." Her eyes looked directly at the ground and her expression softened. Her lips curved in a solemn smile.

"Ugh." Jirou used her index and thumb fingers to rub her eyelids. Sure, she probably wouldn't do the same with Momo but the situation was still concerning. Especially after seeing that expression creep up on her face. "I hope you know what you're doing."

"Yep!" Mina's eyes closed as she beamed.

The rest of the weekend was mostly uneventful. For the first time in a while, Mina had a free schedule. As such, she spent most of it working out. A replacement for her usual cardio activities for sure. The nights were freakishly quiet, filled with long periods of loneliness. Normally, there would be a partner laying next to her, giving her company, fulfilling a need for satisfaction. She reluctantly passed the time watching inconsequential things on her phone, eventually falling asleep deep through midnight. The exact next day also gave her intense separation anxiety, so much so that she decided to go see a certain green haired person.

It would be facetious to say that she wasn't looking forward to having another lesson with him. Simply imagining that hard piston relentlessly pumping into her brought about some drenched undergarments. This didn't matter, she'd be naked in a few seconds anyways. She silently creeped through the halls, eventually arriving at his dorm room door. However, just as she began opening the wooden obstacle, a sound stopped her in her tracks.

"Agh! Deku!" A soft, womanly moan coming from within made Mina's heart jump. With the door held slightly ajar, she poked her eye through the small opening.

Atop the comically All Might themed bed sheets lay a bare Uraraka, whose eyes were covered by her own hand. Her legs were noticeably spread apart. and a conspicuous head of hair poked out of the middle. Izuku was kneeled down, eating out his girlfriend to great success. All Mina could see was that, his head of hair and the gravity girl's covered face.

The sight was jarring, this was the first ever time that Mina had seen someone else partake in anything sexual. Though she had seen porn for reference sometimes, seeing something like this in person was entirely different. Moreover, unlike porn, this gave her stomach a pit.

The thought of seeing him in particular do this with anyone other than herself created a sense of unease. Yes, this present situation was the purpose of her lessons. Strengthening the relationship he already was in, bridging the gap created by a misunderstanding. Yet, every delightful moan escaping her classmate's lips shook her to the core as shivers continually ran down her spine. She closed the door in a respectful and dreadful manner, leaving with a conflicted emotion now brewing.

Mina struggled to fall asleep after walking in on them. The next day saw her getting chewed out in class multiple times over, struggling to keep her eyes open as the monotone tone of their homeroom teacher's voice became a lullaby. At lunch, she sheepishly approached Izuku and scheduled another of their newly agreed on lessons. They barely exchanged words, her tiredness, compounded by what she witnessed the prior night, served as an acceptable excuse to periodically avoid him until their meeting. Therefore, that same night, the door to her room slowly opened.

"Hey!" Mina did her best to put on a fake smile. This time, she wore a casual outfit consisting of a white shirt and blue shorts. Nothing too flashy, she couldn't bother to dress up for some reason. Her mood was all over the place.

"Are we… talking today?" Izuku stepped inside and stood right by the doorway. He rubbed the back of his head, confused about the outfit and her facial expression. His mind already intrinsically made the connection between dressing up and sex with her.

"No! I mean uh… I just went casual this time, you know!" She bent over backwards to hide her jumpiness. Her face showed all teeth, working as shields for her unease.

"Oh, that makes sense, putting intrinsic values on things based off of one experience is foolhardy. I should…" He inaudibly muttered something else as he sat down on the bed. It was endearing how he sometimes lost himself in his own train of thought. His usual routine calmed Mina down, brought her back down to earth. She sat next to him with a soft smile.

"Hey, when you tried with Urara, was it missionary style?" Mina jumped straight to the point. Though, this time she began with actual sex education. She unwittingly ran her hand through her own hair.

"Uh… y…yeah it was." He averted his eyes as he remembered that night. His face became somewhat flushed as a result.

"Well, that's usually a common mistake people make on their first time." Her statement was followed by a look of confusion from the boy next to her. "Look, missionary is great and all but in some cases, it can be painful for first timers." Mina waved one finger in front of her head, visually showing off her knowledge on the topic.

"With that said, I did want your first time in here to be with Urara but…" Mina reached inside her pocket and pulled out a condom. "From now, I'll show you different positions each time!" She bit down on the rubber, holding it with her teeth. Promptly pushing him down, Izuku now laid motionless, his back on the bed.

"W…which position is this?" Mina straddled his thighs as he spoke, her entire backside was facing him. She started to ruffle around on his pants, touching all over his member as she pulled them down.

"Reverse Cowgirl!" She snapped her head back in unison with her own shorts being removed. In addition, she seductively removed her shirt, revealing her chest. Though, unfortunately, she was facing the other way so he would have to wait to see them. Still, they looked supple during that partial millisecond that her side profile revealed.

She leaned over after a ripping sound rippled through the relative silence. Her ass was in full view, squishing against his abs in an arousing manner. Izuku then felt something wet touch his tip, presumably Mina's lips, followed by a rubber sensation covering his entire shaft. The condom was on.

"So … uh… do I need to move?" Growing impatient, he began to want more information on what they were about to do.

"Hehe! You just stay still, and enjoy~" Mina raised her hips directly over his dick, her butt jiggling ever so slightly. She slowly lowered herself over him, aligning her glistening folds with his raging erection.

Even through the protection, Izuku could feel the insanely tight grip engulfing his length. Surprisingly as well, the pink girl above him let out a loud moan as she lowered herself to the downward most point that she physically could. Her vagina was unlike her asshole, this time around the hole welcomed him in, embraced the foreign object. It was almost like he was always meant to be inside this one.

Mina started bouncing up and down, most of his cock pleasurably scraping every fold. She failed to contain each and every moan brought about by their movements. The situation in itself was enough to bring her close to the edge. As much as she wanted to deny it, there was a sprouting feeling of affection making its way to the surface. Her poor attempt at concealing her arousal woke up a somewhat taciturn receptor below. He had been feeling good, sure, but he expected something like their other session. He suddenly shot up and grabbed her thighs.

"W-what Midori w-what are you..?" Izuku wrapped his arms below her kneepits, slowly moving them upwards and placing his palms on the back of her head. He now had Mina in a full nelson by her legs. He took a few seconds to reposition himself, then he started pumping hard and fast.

"Ohhh…. God….. so…." Mina, much like how the first lesson had gone, was now completely blank minded by the explosion in pleasure that the forcible piston brought about. Her previous uncontrollable moans became automatic, filling the air together with a sloshy sound coming off from where they were connected.

His dick started spreading the opening over and over again, rubbing her folds and insides with every insertion. He liked this better, it felt like he was being proactive for the both of them and not just being on the receiving end. After a few more seconds of heated thrusting, Mina went completely silent, her body shook a few times and a considerable amount of liquids shot out from her. Her pussy clamped down as this happened, hugging his protected dick tightly.

Izuku contemplated whether to ask her if she was okay to continue, but it became clear what she wanted once she started to try to bounce in her restricted position. He restarted the upwards pumping to immediate vocal feedback from the girl above him. Once he did so, he realized that the friction happening to the underside of his penis was bringing him closer to the edge. As so, he decided to pick up the speed. He activated his quirk in Full Cowling mode, looking to apply the modification to his movements. Yet he failed to realize that this also effectively converted him into a human vibrator, his body reverberating in accordance to the quirk. This succeeded in granting Mina another quiet orgasm, which she hid quite well this time around. Once he got accustomed to having his quirk whilst engaging in sex, he started thrusting at unfathomable speeds.

"Ah..ah…ah… Izuku… Izuku…Izuku!" Mina, reduced to having simple strands of thought after multiple consecutive climaxes, began ignoring one of her ground rules. She was freely moaning her partner's name.

However, the boy was far too focused on quirk control and movement to notice. The offense went over both of their heads, their minds lost on the pleasure they shared. Her orgasms basically arrived every few thrusts now. His own was close on the horizon. With the speed and overstimulation, the condom wrapped around Izuku expanded, filled with his cum. After a few more seconds of pumping, he released his hold on the girl. Her shapely behind plopped onto his thighs, her hair fell on his lower neck. She was unable to move.

"I'll… help you clean this time." He shifted out from beneath her, rubbing the back of his head after realizing that he had repeatedly taken out his sexual frustrations on her. Would it always be like this, his blue balls from Uraraka released on his friend?

"T..th…thanks …. I'll… do… it… myself…" Mina was catching her breath, she put her forearm over her forehead. Somehow, he had outdone himself and performed even better than in his stellar first lesson. Although, this probably did little to sway her earlier feeling of dread. If he were to do something like this with his girlfriend, would she be able to shrug it off?

"Okay, see you next lesson then!" Izuku put his pants back on and walked out, he caught a glimpse of her exposed chest. As expected, they were a pretty sight.

MIna, exhausted and thoroughly pleasured, laid there silently. She stared at the ceiling, not a thought in mind, her boobs raising up as she breathed. Then a thought, which flashed through for only a second, left a lasting impression. A sentiment that would affect these arrangements going forwards, one that would align with her feelings towards Uraraka.

'I loved that.'

A/N

Yo,

I find it funny that I don't like using the words "Womanhood" and "Manhood" during the sex scenes, given that they're probably the most formal way of referring to those things. Though once you use those words, it feels creepy, like someone who views sex as a matter of fact. Dunno, those words give me an off vibe.

Anyway that's about it, the timetable I set said that this would finish around the 13th, looks more like the twenty something th now.

Have a good day.
