After the afternoon lecture on the female reproductive system, most students had already left the hall. Bakugou Katsuki stayed behind, his notebook filled with neat but confused scribbles. The 23-year-old looked even more handsome up close — tall, broad-shouldered, with those perfectly toned arms straining against his black t-shirt and messy black hair falling over his doe eyes. He approached Professor Todoroki Shouto with a shy, frustrated expression.

“Professor… I’m really struggling with this chapter,” Katsuki admitted, voice low and respectful. “The female reproductive system and anatomy… it’s so complicated. The diagrams in the book don’t make it click. I need to understand every part perfectly if I’m going to score the highest marks.”

Shouto’s face lit up with that proud, nerdy smile. This was exactly what he needed. Katsuki acing everything was his golden ticket to becoming the youngest HOD.

“Don’t worry, Katsuki,” Shouto said, clapping a strong hand on the younger man’s shoulder. “I can give you private tutoring. How about this evening? Come home with me after my last class. We’ll go through it step by step at my place. I have a whiteboard and all the materials.”

Katsuki’s eyes widened in relief and gratitude. “Really, Professor? That would be amazing. Thank you so much!”

That evening, Shouto drove Katsuki to their upscale apartment complex. The moment they stepped out of the elevator and reached the door, Shouto rang the bell.

Izuku opened the door, and Katsuki’s breath caught in his throat like he’d been punched in the chest.

She looked like pure walking sex.

Her white skin glowed under the hallway lights. Those massive, heavy tits were barely contained in a tiny, sheer pink babydoll top that was practically see-through. Her dark pink nipples were hard and clearly visible, poking shamelessly against the thin fabric. The “dress” ended right below her ass — so short that the bottom curves of her fat, juicy ass cheeks peeked out. No bra. No panties. Just smooth white thighs and the faint outline of her puffy pink fat pussy lips when she shifted her weight. Her pink lips were glossy, and her long hair fell messily over one shoulder. She looked ready to get fucked on the doormat.

Katsuki gasped audibly, his cock twitching instantly in his jeans. “Holy shit…” he whispered under his breath before he could stop himself.

Izuku’s eyes instantly locked onto the tall, muscular young student. She drank him in — those broad shoulders, the way his t-shirt hugged his chest, the obvious bulge already forming in his pants. Her pink fat pussy clenched hard, a fresh gush of slick dripping down her inner thigh. She bit her lower lip, already imagining that young, thick cock stretching her.

Shouto, completely oblivious as always, smiled warmly. “Izuku, this is Bakugou Katsuki — my brightest student. Katsuki, this is my wife, Izuku.”

Izuku extended her hand with a sultry smile, her voice dripping honey and filth. “Hi, Katsuki… wow, you’re so tall and handsome. Nice to meet you, baby.”

Katsuki shook her hand, feeling how soft and warm her skin was. His voice came out a little hoarse. “H-Hi, Mrs. Todoroki… nice to meet you too.”

“Please, call me Izuku,” she purred, holding his hand a second longer than necessary, her thumb stroking his skin. “No need to be so formal with me.”

Shouto chuckled innocently. “Katsuki’s here for private tutoring on the female reproductive system. I’ll set up the whiteboard in the living room. Make yourself comfortable, Katsuki.”

As Shouto walked away to arrange the small whiteboard, markers, and notes on the coffee table, Izuku turned her full attention to Katsuki. She stepped closer, her massive tits almost brushing his chest.

“So… how old are you, handsome?” she asked sweetly, tilting her head so her glossy pink lips looked even more fuckable.

“I’m 23, Izuku,” Katsuki replied, trying not to stare at her hard nipples.

“Mmm, 23… so young and strong,” she cooed, her voice low and slutty. “You must have so much stamina. Girls your age must be dying to get a piece of you. Do you have a girlfriend, baby? Someone who takes care of that big, young cock of yours?”

Katsuki flushed deep red, his cock stirring harder. “N-No… no girlfriend. I’m too focused on studies.”

Izuku giggled softly, stepping even closer so the side of her heavy left tit pressed firmly against his arm. “Poor boy… all that energy and no one to drain it. That’s such a waste.”

She turned slightly to “help” Shouto by picking up a marker from the floor. Bending over slowly with her legs straight, her tiny babydoll rode all the way up, completely exposing her fat, round ass and the swollen, pink, dripping pussy lips between her thighs. Her pussy was visibly wet, a shiny string of arousal stretching down.

Katsuki’s eyes widened, staring helplessly at her bare cunt. His cock was now fully hard, tenting his jeans obscenely.

Izuku straightened up slowly, “accidentally” letting one tit slip out of the loose top for a second before tucking it back in. She brought Katsuki a glass of cold juice, pressing her body against his side as she handed it over.

“Here, drink this, baby. You look so thirsty,” she whispered, her breath hot against his ear. Her nipple dragged across his bicep as she leaned in.

Katsuki gulped the juice, his hands shaking slightly. “Th-Thank you…”

Shouto finally finished arranging everything. “Okay, let’s start! Sit down, Katsuki.”

The tutoring began, but Katsuki was completely distracted. Every time Shouto pointed to a diagram, Katsuki’s eyes kept drifting to Izuku, who had perched herself on the arm of the couch right next to him. Her legs were slightly spread, giving him teasing glimpses of her puffy pink pussy.

Shouto noticed Katsuki’s confusion and frowned, clearly worried. If Katsuki didn’t understand this perfectly, his own dream of becoming the youngest HOD could slip away.

Suddenly, an innocent idea struck the nerdy professor.

“Izuku,” Shouto said brightly, “why don’t you model naked for us? It’ll be much easier for Katsuki to understand the female anatomy if he can see it on a real body. You don’t mind, right? It’s just educational.”

Izuku’s eyes lit up with pure slutty joy. She tried to look surprised but failed miserably. “Of course, honey. Anything to help your favorite student.”

Katsuki’s mouth fell open. “P-Professor… are you sure? I-I mean—”

Before he could finish, Izuku stood up and stripped right there in the living room like the born whore she was.

She peeled off the tiny babydoll top, letting her massive, heavy tits bounce free. They were perfect — big, round, with puffy pink nipples already rock hard. Then she shimmied out of the short skirt, revealing her completely bare, dripping pink fat pussy. The plump outer lips were swollen and glistening, her clit peeking out. She turned around slowly, shaking her fat ass teasingly so both men could see the full jiggle.

Katsuki’s cock throbbed painfully in his pants. “Oh fuck…” he breathed, eyes glued to her naked body.

Shouto smiled proudly, completely innocent. “Perfect! Lie down on the coffee table, Izuku. Make yourself comfortable.”

Izuku happily lay back on the low table, spreading her legs wide — much wider than necessary. Her pink fat pussy opened up obscenely, inner lips shiny and dripping. A thick drop of her arousal slowly leaked out and landed on the table with a soft plop.

Shouto picked up colored markers with pure academic excitement. “Alright, Katsuki, pay attention.”

He started drawing on Izuku’s body like she was a living diagram.

First, he labeled her massive tits in blue marker: “BREASTS” across the top of each heavy globe, then “NIPPLES” circling her puffy pink peaks. He wrote “AREOLA” around the darker pink areas.

Izuku moaned softly, biting her lower lip and looking straight at Katsuki with pure lust in her eyes. “Mmmhh… that feels… interesting…”

Shouto chuckled. “Ticklish, honey? Sorry.”

Next, he moved between her spread thighs. He labeled her outer lips “LABIA MAJORA,” then carefully wrote “LABIA MINORA” on the inner folds. Right above her swollen clit, he wrote “CLITORIS.” Lower down, he marked “VAGINAL OPENING” and even drew a small arrow pointing inside her dripping hole.

Izuku’s pussy clenched visibly at Katsuki, opening and closing like it was winking at him. More slick dripped out, pooling on the table under her ass.

“Ahh… mmm…” she moaned louder, her hips twitching.

“Izuku, lower your voice please,” Shouto said absentmindedly while drawing. “It’s disturbing the class.”

“Sorry, honey…” Izuku whispered, but her voice was still breathy and slutty. She looked at Katsuki and mouthed silently, “I’m so fucking wet for you.”

Shouto made her turn over onto her stomach, her fat ass up in the air. He labeled her ass cheeks “GLUTEUS MAXIMUS,” then spread them slightly to write “ANUS” around her tight little hole.

Izuku shook her ass playfully while he wrote, making her big tits squash against the table.

Then she turned back onto her back, legs spread even wider, pussy now visibly throbbing.

Katsuki was supposed to explain the parts on the whiteboard while pointing at Izuku’s marked-up body, but he could barely speak. His cock was rock hard, leaking pre-cum into his boxers.

“U-Um… the labia majora are the outer… protective folds…” he stammered, eyes locked on her dripping cunt.

Izuku bit her lip harder, her slutty face flushed with arousal. While Shouto was busy adding more labels near her tits, she clenched her pussy lips again, making them pout and wink directly at Katsuki. A long, sticky string of her juices stretched from her hole to the table.

“Mmmhh… yes, baby… look at my wet little pussy…” she whispered very softly so only Katsuki could hear, her voice dripping filth.

Shouto, still the clueless nerd, smiled. “See, Katsuki? Real-life application makes it so much clearer. You’re doing great!”

Katsuki swallowed hard, his face burning, cock aching. “Y-Yes, Professor… very clear…”

Izuku moaned again, low and slutty, her hips rolling slightly as if begging to be fucked right there on the table while her husband drew educational diagrams all over her naked, dripping body.

The tutoring session had only just begun, and Izuku’s pink fat pussy was already starving for Katsuki’s young, thick cock.
