Lustful Fanfictions

After a strange yet fairly 'normal' breakfast session for the Bakugo family, Rex—who had now completely possessed Katsuki—grunted in annoyance when his mother, Mitsuki, asked him to help wash the dishes.

"Tch! What a hassle!" he grumbled, imitating Bakugo's habit of always complaining. However, his hands still swiftly reached for the dirty plates. His mind was still spinning rapidly, devising a strategy to conquer this new world. Where should he start? Develop his Quirk? Seek more information about the future? Or, maybe... take advantage of the opportunity before him.

Mitsuki, with her bright blonde hair tied back in a messy ponytail and her sharp yet beautiful face, snorted beside him. "Stop complaining so much! A boy should be able to help his mother! You want to be a hero but you're just lazing around, huh?!" She slapped Katsuki's head lightly, but there was no real violence behind the action. It was more like a rough form of affection from Mitsuki.

Katsuki snorted again, deliberately ignoring the slap. He focused on the plate, but his ears remained alert. Until finally, the unexpected happened.

After the last of the plates were rinsed and stacked, Katsuki slid off his chair with a slight jolt. "That's it! Satisfied?!" he said, wiping his hands on his shorts.

Mitsuki, who had been watching, smiled faintly. It was a strange smile that made Rex feel uneasy. "Good, kid. Now, it's your turn to clean up." She stepped closer, her eyes boring into Katsuki with an unusual intensity. "Come on, Katsuki. Let's take a bath with Mommy."

Hearing that, Rex's heart skipped a beat. Memories of Katsuki and his mother's "relationship," sometimes unconventional to outsiders but natural to them, flashed through his mind. This was the moment. This was a chance to understand this body better, beyond just its quirk or past memories. A chance to observe it up close.

"What?! How could I possibly bathe with you, hag?! I'm a big boy!" Katsuki exclaimed, trying to maintain Bakugo's independent personality. Though Rex was screaming with joy inside.

Mitsuki snorted. "Excuses! You're still a child! Mommy's always bathed you since you were little. Hurry up, don't talk too much!" She grabbed Katsuki's hand, pulling him forcefully toward the bathroom. Mitsuki's surprising strength, typical of a woman with a glycerin Quirk, was felt in her grip.

Katsuki pretended to struggle, but silently followed. "Let go of me, hag! I can bathe myself!"

They entered the spacious bathroom, filled with warm steam from the already-filled bathtub. The scent of soap and shampoo wafted through the air. Mitsuki locked the door behind them.

"Well, it's here," Mitsuki said, releasing Katsuki's hand. "Now, take off your clothes. Mom will rub your back."

Katsuki stood there for a moment. This was it. The moment he'd been waiting for. With a hint of undisguised hesitation, he began to remove his pajamas.

Mitsuki, without further ado, immediately removed the towel wrapped around her body. And that's when Katsuki—or rather, Rex—was stunned.

Rex's eyes, in Katsuki's body, widened. Mitsuki's body was clearly visible before him. His body... oh, Mitsuki Bakugo's body was far more stunning than he had imagined from mere pictures or descriptions.

The body of a mature woman is well-proportioned and curvaceous. Her skin is pure white, slightly reddish from the steam. Her breasts are full and beautifully perky, with dark pink nipples, slightly puckered by the cool air. Her stomach is flat, without any signs of excess fat, showing the subtle abdominal muscles, a result of her energetic nature. Her waist is slender, contrasting with her wide, full hips, creating an alluring curve. Her thighs are firm and smooth, ending in long calves. Her lower part, her intimate area, is well-groomed, with pubic hair trimmed short and neatly, forming a perfect little triangle. Her entire body exudes an aura of strength and mature female allure, an intoxicating combination.

Katsuki (Rex) was momentarily mesmerized, his mind immediately filled with desire. Rex's primal instincts took over. The woman before him was the pinnacle of forbidden pleasure, a mother he shouldn't have desired like this. But Rex was Rex. His ambition knew no bounds, let alone moral ones.

Mitsuki, noticing Katsuki's fixed gaze, grinned. A small laugh escaped her lips. "What's wrong, Katsuki? Fascinated by Mommy? You know how hot Mommy is, right? Don't keep pouting, Mommy won't be able to see how shocked you are," she teased, with her characteristically proud tone. She turned her body slightly, deliberately showing off her curves, as if challenging him. "Look, Mommy's body is still toned, unlike other women my age. It's because Mommy is always horny!"

Katsuki jerked out of his reverie, his red eyes lighting up again, this time with Bakugo's signature competitive gleam, mixed with Rex's lust. Bakugo's stubbornness and Rex's cunning united. He didn't want to lose.

"Hmph! What's so good about it?! It's just passable!" Katsuki exclaimed, trying to hide his amazement with a sneer. "You should be the one who's amazed by me, hag!"

Without waiting for Mitsuki's response, Katsuki immediately removed the towel he had been wearing. Bakugo Katsuki's petite body was completely naked. And that was when Mitsuki saw an unexpected sight.

Although Bakugo Katsuki's body was still small and stocky, like a child his age, his cock... it was sticking out, huge, and hard. It was clearly abnormal for his age, even looking too big for a child's body proportions. It was Rex's massive cock, which had somehow been reincarnated with him.

Seeing Katsuki's big, hard cock, it was Mitsuki's turn to be captivated. Her piercing eyes widened, her mouth slightly open in disbelief. A faint blush crept across her cheeks.

She expected to see a small, innocent boy. However, what she saw before her was something far beyond her expectations. Katsuki's cock, already erect and hard, stood erect. Its size... it was much larger than she had imagined for a boy his age. In fact, she had to admit, even Masaru's cock wasn't even half that size.

She had seen her husband, Masaru's, cock countless times, but it wasn't even half the size and firmness of Katsuki's cock before her. This... this was something extraordinary, unexpected, and... it stirred a desire that had long been pent up inside her.

Mitsuki's face flushed red, her jaw slightly agape. "K-Katsuki?! W-what was that?! How could that be...?! You idiot! Who taught you that?!" There was a mix of surprise, slight shock, and unconcealed interest in her voice.

Katsuki grinned, a triumphant grin typical of Rex, but now plastered on Bakugo Katsuki's face. He knew he had turned the tables. "Hmph! This is what size is, hag! Why? Impressed, right?! You didn't expect your son to have one this big, did you?!" He puffed out his small chest, cockily.

Mitsuki swallowed, her gaze unable to tear away from Katsuki's cock. "N... no way! This... this is weird! But... but... it's so big..." She muttered. A naughty idea came to her mind. This was going to be a very interesting game. "Okay, Katsuki. Don't get cocky yet. Let's see how 'great' your cock really is." Mitsuki stepped closer, her gaze turning bolder, more seductive.

She raised her hand, touched Katsuki's cheek, then her fingers moved down to his neck. Katsuki shivered slightly. "What are you going to do, old woman?" he asked, his voice a little choked.

Mitsuki laughed softly, a laugh full of passion. "We'll see." Her hand continued down, across Katsuki's chest, and stopped right at the base of his cock. Her fingers played there, a light touch that made Katsuki's cock twitch. "You're very sensitive, Katsuki. Just like Mom."

Katsuki sighed. "Shh... Shut up."

Mitsuki chuckled. "Can't wait, huh? Okay. I'll show you. But you have to obey." With that, she gripped Katsuki's cock more firmly and began to stroke it slowly.

"Ah! Mommy!" Katsuki moaned loudly, his eyes closed.

Mitsuki chuckled, moving closer, her naked body pressed against Katsuki's. She kissed Katsuki's neck, sucking on it, then moved down to Katsuki's small chest, sucking on his already erect nipples.

"Ahh! Nggghhh! Mom!" Katsuki groaned, his head tilted back.

Mitsuki leaned in, her lips now inches from Katsuki's. "You know, this is the first time I've felt a cock this big... I'm curious." She looked up, her eyes meeting Katsuki's red ones. "How about we try something more... deeper?"

Katsuki didn't need to think twice. Rex's mind, full of strategy and desire, was now in complete control. "Just do it, hag!"

Without another word, they kissed wildly. A passionate kiss, filled with curiosity, broken taboos, and unstoppable desire. Their mouths devoured each other, their tongues battling, reflecting both of their stubborn and dominant natures. Mitsuki's hand continued to stroke Katsuki's cock, while Katsuki's hands, still small but strong, gripped Mitsuki's hips tightly, pulling her closer, as if wanting to unite their bodies more deeply. The air in the bathroom grew hotter, filled with stifled moans and ragged breaths.

An unspoken agreement has formed between this unlikely mother and son. Moral boundaries have crumbled, replaced by an unstoppable surge of passion.

The kiss between Katsuki and Mitsuki grew more intense and wild, their lips devouring each other, tongues intertwined in a dance of intoxicating passion. Warmth flooded the bathroom, steam mixing with the heat radiating from both of them. Katsuki (Rex), would not waste this golden opportunity. His small but agile hands moved quickly, kneading Mitsuki's large and plump breasts. His fingers twisted Mitsuki's already erect nipples, pinching them passionately.

"Mmmph! Nggghhh! Katsuki... that... that feels so good... Ahhh!" Mitsuki moaned between kisses, her back arching, feeling the intense waves of pleasure radiate from her breasts. She pressed herself tighter against him, as if wanting to absorb every touch. "Harder, Katsuki... squeeze my breasts... pinch my nipples... I love it!"

Mitsuki, also unwilling to lose in this game, and with her bold and dominant nature, moved her hands quickly. She grabbed Katsuki's large, erect cock, stroking it with her thumb, feeling every protruding vein. A faint, passionate smile spread across her lips.

"You're not bad either, my boy," Mitsuki grunted, her voice hoarse with arousal. She ran her fingers along Katsuki's cock, from base to tip. "Your size is no joke. It's even bigger than your father's..."

They continued kissing, attacking each other with passion, until finally, they were forced to break apart due to lack of breath. Their breaths were ragged, their chests rising and falling rapidly, their eyes staring into each other's, radiating a burning passion.

"Hah… Hah… You… are so aggressive, old woman," Katsuki panted, a mischievous smile etched on his lips.

Mitsuki snorted, cupping Katsuki's face with both hands. "Don't underestimate Mommy, brat. Mommy can do better than this."

Then, without much word, the two lay down on the warm bathroom floor, on the towels they had spread out. An unspoken agreement had been made: this was a contest, a battle of passion in which neither wanted to lose.

Katsuki (Rex), with his cunning and skilled skills in pleasuring women, immediately made his move. He brought his face close to Mitsuki's already wet and swollen vagina. Her sensual scent, mixed with the scent of arousal, immediately filled his senses. Katsuki began licking Mitsuki's clitoris with great care, but also with just the right amount of pressure. His tongue danced nimbly, sucking and swirling, and nibbling on her clit.

Mitsuki arched her back, a deep moan escaping her throat. "Ohh... Katsuki... Ahh... Oh God... Don't stop... There... my clit .. Ahh!" Every touch of Katsuki's tongue, every suck and bite of hers, made Mitsuki's body tremble violently. "You... where did you learn this?! Ahh! So... so good... My clit ... Ohh!" Her breasts shook with each moan.

Not only that, Katsuki's other finger didn't stay still either. He poked into Mitsuki's warm, wet pussy, swirling his finger against her walls, trying to reach her G-spot.

"Aaaahhh! Katsuki! Your finger...! It's... it's inside...! Nggghhh! Deeper! Touch my womb! I... I'm going to... hah... cum again! My pussy... is throbbing... so throbbing!" Mitsuki moaned, her arousal growing, her legs shaking uncontrollably.

While Katsuki worked on Mitsuki, Mitsuki didn't sit still. She gripped Katsuki's erect cock tightly, guiding it into her mouth. With undeniable skill, Mitsuki began kissing the tip of Katsuki's cock, licking it slowly from the tip down to the balls, tasting every inch. Then, she began sucking on it, taking most of Katsuki's shaft into her mouth, moving back and forth in a mesmerizing rhythm.

"Mmmph! Ohhh! Mom... ngghh! Your tongue...! That... that feels so good! Suck it deeper! Ahhh! My cock... it feels... it feels like it's going to explode!" Katsuki groaned, his back arching, feeling the incredible sensation of pleasure in his cock.

They both competed with each other, neither willing to lose in this battle of pleasure. Katsuki continued to lick and twist Mitsuki's clit, his fingers actively rotating inside her pussy, sometimes pressing upwards, touching Mitsuki's cervix, making Mitsuki scream in delight. Mitsuki also deepened her sucking, her lips sucking hard on Katsuki's cock, occasionally her tongue playing with the head of the cock, making Katsuki tremble violently.

Neither one wanted to be outdone in the pleasure-giving process. Mitsuki thrust deeper, occasionally touching the base with her tongue, making Katsuki moan. "Ohh... Keep going... On my cock ... Suck it deeper, hag!"

On the other hand, Katsuki continued to lick and suck Mitsuki's clit with increasing intensity, his fingers exploring her pussy more and more boldly. "You too... Ahh... My pussy is so wet... Licking... It makes me want more... Ohh..."

The two of them sank deeper into a whirlpool of passion. The sounds of moans and groans echoed, filling every corner of the bathroom. Their bodies tensed, the sensations reaching their peak, and at the same time, they cried out in satisfaction.

"Ohhhh! Nggghhh! Katsuki! You... you're driving me crazy! I'm going to cum! My clit...! My pussy...! I can't take it anymore! Ahhhhhhh! I'm cumming!" Mitsuki screamed loudly, her body convulsing.

"Mom! Me too! I'm going to cum! Suck harder! Nggghhh! My cock...! I... I can't hold it anymore! Ahhhhhhh!" Katsuki roared, feeling an unbearable wave of pleasure.

And finally, they came together. Love juices filled each other's mouths. Katsuki felt Mitsuki's juices explode in his mouth, a warm, savory sensation filling his mouth.

Mitsuki also felt the same way, Katsuki's sperm spurted out several times, filling her mouth.

Without hesitation, both of them drank and gulped down the liquid. Katsuki tasted Mitsuki's slightly salty yet sweet liquid, flowing down his throat. Mitsuki tasted Katsuki's warm, thick liquid, a sense of dominance and indescribable pleasure. Both of them loved this new taste, the taste of themselves mixed with each other.

After swallowing everything, they looked at each other. Katsuki's red eyes met Mitsuki's piercing ones. There was passion, satisfaction, and a new understanding between them. A small laugh, slowly growing, escaped both of their lips. It sounded insane, yet filled with relief and pleasure.

"Hah... Hah... You're not bad, for a little kid," Mitsuki panted, but her pride was clearly audible.

"Tch! I told you, didn't I? I'm the best!" Katsuki retorted, his voice a little hoarse, but with his trademark arrogance. "You're not bad either, for an old woman."

"What did you say?! Do you want Mommy to hit you?!" Mitsuki threatened, but her smile didn't fade.

Katsuki just snorted, enjoying the moment. This was a... very interesting start.
