Jahhhh... home sweet home.
Izuku pushed the door of classroom 1-A with his shoulder, letting it slide open with a soft creak. The room was empty except for two figures waiting for him at their desks.
Momo had a notebook open in front of her, scribbling annotations with a concentration that made her gray eyes shine. Uraraka swung her legs as she waited, leaning against her desk with a hopeful smile.
Izuku closed the door behind him and looked at them both.
Your son made it, Mom. I'm a success. I've got two cute girls waiting for me right after I just touched the breasts of my teacher, the hottest one in all of U.A.
He felt a warm pressure behind his eyes, a wave of ridiculous and completely inappropriate emotion that threatened to overflow. A tear slid down his cheek before he could stop it.
"I-Izuku, are you crying?" Ochako sat up at once, her face filling with concern as her eyebrows knit together. "What's wrong?! Are you okay?! Tell me nothing hurts! Do you need me to call Recovery Girl, or... or to help you with something?!"
Momo looked up from her notebook and frowned at the state of his glassy eyes.
"Forgive me for being so direct, but... are you all right?" Momo frowned slightly, observing him carefully. "Your eyes look rather irritated, almost glassy. Was the corrective session with Midnight sensei more... taxing than you'd anticipated? I distinctly recall you mentioning to Uraraka san that everything had gone favorably. Has something happened that we should know about?"
"Ahem, ahem..." Izuku wiped his cheek with the back of his hand and cleared his throat loudly, recovering his composure. "It's nothing. I faced everything like a man and it went better than I expected. THESE ARE TEARS OF JOY!"
Ochako exchanged a confused look with Momo.
Suddenly, Izuku remembered something.
Mmmhhhh... now that I think about it, I brought a blonde assassin home to live with us, I touched Midnight's breasts, mom knows I groped Ochako on my first day, and on top of that, sooner or later she's gonna find out I did the same to Momo's butt...
A cold sweat began to run down his back.
Ahem, maybe... maybe mom won't be so proud of her son after all.
"All right, Izuku kun," said Momo, pulling out her research notebook and opening it to a page filled with diagrams and meticulous notes. "I've been reflecting on the data we collected during the cafeteria incident, and I've reached several preliminary conclusions that require immediate empirical verification."
Izuku blinked.
Aw, crap. Here we go again with the mad scientist mode.
"Specifically," Momo continued as she pointed at one of her diagrams with her index finger, "we need to establish a definitive correlation between subcutaneous adipose tissue density and Booster transmission efficiency. My initial hypothesis suggests that areas with a greater concentration of body fat act as more efficient conductors for your enhancement energy, but that directly contradicts the data we obtained when you touched my gluteus compared to my breast."
"Momo..."
"Because, you see, anatomically speaking, the gluteus maximus has a greater muscle mass underlying the adipose tissue, which could indicate that the determining factor isn't merely fat. The combined muscle to fat ratio would make more sense. However, that still doesn't fully explain why contact with my breasts during our first encounter produced such dramatic results in the lipid cost reduction when my breasts have a predominantly glandular composition with..."
"Momo."
"...lower adipose tissue density compared to my gluteus. Which leads me to consider the possibility that there's a neurological component we haven't taken into account. Nerve endings are significantly denser in certain areas of the female body, specifically in erogenous zones such as the breasts and the buttocks, and if your Quirk is utilizing neural pathways as transmission channels for the Booster, then the sensitivity of the area touched could be the critical factor rather than the tissue composition, which would open an entirely new field of research regarding..."
"MOMO!"
Izuku walked straight toward her with determination in every step. Ochako watched them from her seat with a curious expression while Momo stayed completely absorbed in her notebook.
"...the interaction between sensory stimuli and Quirk enhancement, because if we assume that nerve signals amplify the effectiveness of the Booster, then we'd have to consider the possibility that areas with greater innervation produce exponentially superior results, although that would require controlled testing across multiple body areas to establish a sensitivity versus efficiency map, and frankly I'm not certain how to design an experiment that's both scientifically rigorous and socially appropriate given that we'd be discussing physical contact in zones increasingly..."
Izuku reached her and, without warning, placed both hands directly on her breasts. His fingers sank into the blazer fabric as he squeezed firmly.
"A-Ah...!" she let out, her voice losing all its academic authority in an instant.
The notebook, the pride of her meticulousness, slipped from her fingers and hit the floor.
"Perfect," said Izuku with a satisfied smile. "Now we can start with the practical part without my head hurting."
Momo's face turned completely red as her hands trembled in the air, not knowing where to land.
"I-Izuku... please, I beg you to maintain your composure. We're in one of the academy's classrooms and... it's extremely improper for us to be seen in such an... ambiguous situation. A classmate or professor could burst in at any moment and our academic reputations would be compromised."
"The room is empty," Izuku replied calmly while keeping his hands exactly where they were. "And we need real data, right? You said it yourself."
God, they're so soft, he thought as he felt the warmth pass through the fabric. Every time I touch them it's like discovering paradise all over again.
Ochako got up from her seat and approached with quick steps, her cheeks slightly flushed though her eyes shone with curiosity.
"So you've already moved on to the experimentation phase?!" Ochako exclaimed, leaning in to watch up close how Izuku's fingers sank into Momo's bust. "Tell me, Izuku! What exactly are we testing this time? If this is gonna help you control your power better, I wanna know how it works too!"
Izuku felt the familiar activation of his Quirk.
[QUIRK ANALYSIS INITIATED][BOOST MODE: ACTIVE][ANALYZING...]
He waited for new information to appear, some additional discovery about Momo's manual, but nothing came. The same analysis as always unfolded before his eyes.
Nothing new. Izuku frowned slightly. I thought something would change.
"Momo," he said while keeping the contact, "create something. Anything."
Momo, still red and visibly self conscious, closed her eyes and concentrated. Her skin glowed and in less than two seconds an advanced chemistry textbook appeared in her free hand.
Momo opened her eyes and examined the book.
"The creation time was excellent," she murmured as she flipped through the pages. "And the lipid cost was minimal, just as I expected with the Booster active. But..."
She frowned.
"It doesn't seem any different from the other times you've used your Quirk on me, Izuku kun."
Izuku slowly pulled his hands back, processing the information.
So touching both breasts doesn't produce a different effect than touching just one, he thought as he watched Momo pick up her notebook from the floor. Why? If I'm maintaining contact at two points simultaneously, there should be some change, right?... Isn't that how my pervy powers work?
Momo stood up, adjusting her blazer with dignified movements despite the persistent flush on her cheeks.
"Izuku kun, I believe we should test with different areas of the body," she announced as she opened her notebook to a new page. "If my hypothesis regarding the neural pathways is correct, then the combination of zones with different nerve ending density could produce different results."
She paused, her voice dropping slightly in volume as her cheeks turned even redder.
"That is... perhaps you should attempt to touch... the pectoral zone and the gluteal region simultaneously."
Ochako, who'd been watching in silence, let out a small choked sound.
Izuku felt his brain stop for one full second.
Did Momo Yaoyorozu, the proper rich girl, the class vice president, just scientifically suggest that I touch her breast and her butt at the same time?
"From an anatomical perspective," Momo continued in a trembling but determined voice, scribbling notes frantically, "the gluteus has a significantly greater muscle concentration than the mammary tissue, which could create a synergistic effect if your Quirk is utilizing multiple types of tissue as transmission channels. The only way to confirm this hypothesis is through direct experimentation."
She looked up from her notebook and stared at him with gray eyes full of scientific determination mixed with embarrassment.
"Therefore... I agree to participate in the experiment."
Momo Yaoyorozu, Izuku thought with gratitude. You're officially my favorite heroine in the whole world.
"Turn around," Izuku instructed.
Momo obeyed, turning her back to him as her shoulders tensed with anticipation. Izuku placed his left hand on Momo's right buttock, feeling the muscle firmness through the fabric. With his right hand, he wrapped around her waist from behind and slid up to her left breast, squeezing gently.
"Ahh..."
The sound that escaped Momo's lips was involuntary and completely indecent.
Izuku felt the activation of his Quirk intensify immediately.
[DUAL ZONE CONTACT DETECTED][MAMMARY TISSUE + GLUTEAL MUSCLE][ANALYZING NEURAL PATHWAY SYNCHRONIZATION...]
Wait. What?
[CRITICAL DISCOVERY: BOOST INTENSITY MULTIPLIER DETECTED][STANDARD SINGLE POINT CONTACT: 100% BASE EFFICIENCY][DUAL ZONE SIMULTANEOUS CONTACT (DIFFERENT TISSUE TYPES): 175% EFFICIENCY][THEORETICAL SCALING: Each additional distinct contact zone adds 75% to base efficiency. Maximum theoretical efficiency with full body contact across multiple tissue types: 400% base.]
Izuku felt his eyes go wide with surprise.
So it's not just touching two points. It's touching two DIFFERENT TYPES of tissue at the same time... or something like that.
"Momo," he said in a voice tense with excitement, "try to create something."
Momo extended her trembling hand and activated Creation. Her skin glowed with blinding intensity, and in less than a second a complex object appeared in her hands: a functional drone with four propellers, an integrated camera, and a remote control circuit visible through the transparent casing.
Momo stared at the object in disbelief.
"This... this should've taken me at least twenty seconds," she whispered with a shaky voice. "And the lipid cost should've left me dizzy. But... I don't feel anything. It's as if my Quirk were operating on a completely different level."
Izuku slowly pulled his hands back, processing all the new information.
"You were right," he announced as Momo turned to look at him with eyes shining with curiosity. "Multiple contact DOES amplify the Booster, but only when I touch different types of tissue simultaneously."
"Different types of tissue?" Momo repeated as she grabbed her notebook again, scribbling notes at a frantic pace. "That... that confirms my hypothesis. The nerve signals from glandular mammary tissue and gluteal muscle tissue would travel through distinct neural pathways, creating complementary transmission channels rather than redundant ones."
"Exactly," Izuku confirmed. "When I touched both breasts, there was no change. But when I combined breast and butt..."
"The effect multiplied," Momo finished, her brain already processing the tactical implications. "Izuku kun, that means that in real combat, the strategic placement of your hands could mark the difference between a moderate enhancement and a transformational one."
Ochako stood up from her seat and approached, her expression lit up with enthusiasm.
"So how strong was the Boost this time?" she asked.
"One hundred and seventy five percent," Izuku replied. "Compared to the one hundred percent base of single contact."
Momo whistled softly.
"Seventy five percent additional improvement just from the strategic location of the contact," she murmured as she calculated. "If the pattern holds, then three distinct zones would produce two hundred and fifty percent, and four zones would reach..."
"Three hundred and twenty five percent," Izuku finished. "With a theoretical maximum of four hundred percent if I achieve complete body contact across multiple types of tissue."
Ochako swallowed hard.
"That's... incredible, Izuku kun. You could turn any hero into a version of themselves four times more powerful."
"That's why I need to keep researching," said Izuku as he looked at both girls. "Ochako, would you be willing to help us with more tests?"
Ochako tensed for a second, considering what that meant.
EEEEEEEEEEEEEHH?! S-S-Seriously?! I-I-Izuku kun just asked me THAT with such a serious and determined face?!
UWAAAAAAAAAAAAAAA!!!
Calm down, Ochako! Calm down! Breathe... inhale, exhale! But... but it's just...! Izuku kun's hands! On my... and also on my...! AT THE SAME TIME!! That's way too much information for my poor hands! I feel like I'm gonna start floating and never come back down!
I can't fall behind... if I chicken out now, I'm gonna be holding back Izuku kun's progress! He's working so hard to understand his Quirk... and if I can be of help to him... if my... ahem... 'zones' can help him become an even better hero...
I CAN'T BE A COWARD!!
"Y-Yes! I totally get it!" she nodded with such vigor that locks of her hair bounced. "If this is what you need to understand your Quirk and become an even more amazing hero... then I have no reason to hesitate! Count on me, Izuku kun! I'll give it my all to make the research a success! PLUS ULTRA!"
