Renji had heard about it before. But he'd never met anyone who actually had it, he'd never even thought it was a real kink outside the outrageous fantasies he read in hentai comics.

Sensory overload kink was a form of BDSM-edged erotic play where one partner deliberately flooded the other's nervous system with intense, layered, or conflicting sensations.

Renji didn't know for sure if Ms Katsura fully had a sensory overload kink or if her brain simply reacted stronger to her senses, causing her to get overstimulated by the slightest of acts.

But this was exciting.

First, he found out Reina had an impregnation kink, Haruka has a sex slave kink, Miyu is a shame-based masochist, Miyako has a cum addiction, and now, Ms Katsura is highly stimulated.

Discovering kinks in all these milfs was another thrill he hadn't even expected.

The sensory overload was a more glaring kink though, the peak of it was when the brain was no longer able to process the overload of sensations normally, leading to brain fuckery where she would just turn to a mindless cock-hungry slut.

Not even able to say coherent words.

The idea of doing that to jugdy Ms Katsura, who was about to report him tomorrow to the principal, exhilarated Renji even more.

The goal was to push her past the point of "pleasant" stimulation into a raw, overwhelming state where pleasure, pain, discomfort, and ecstasy blur together.

Renji wondered if he would go all the way. He didn't want to actually hurt her or anything.

At first, it would be about a single sensation, making her focus on it, feel it as its volume increases on wherever part of her body it was.

Then, he would add another sensation, and another, making her feel the volumes of them all and the contradiction.

Too much, too many, too fast, all at once.

He could turn his literature teacher into a fuck puppet.

Intrigued, Renji decided to test it. "You like that, huh? Your tits are so fucking sensitive."

Kaori whimpered, her lips shivering as she felt his hands knead her breasts like toys. "Please, take it easy. Your hands… it's making me… tremble."

Renji smiled, whispering into her quivering ear. "That's because you're hypersensitive, Ms Katsura."

Kaori whispered a gasp, her cheeks turning red in guilt. "I don't know… ngh… what you're talking about."

Renji chuckled. "Don't lie, Ms Katsura. There's no way you wouldn't have realized by now that you react to things more than the normal person. I remember now how your face had squeezed when I grabbed your breasts back in Haruka's house. You must have gotten wet so fast."

Kaori shook her head. "That's not true… Please just… just stop this now, Renji."

"But I don't want to stop," Renji whispered. "I want to explore your hypersensitivity. Don't you see? It makes sense now." He scooped her breasts from under and squeezed all the way to her nipples, tickling them as she shivered, lips shaking and body spasming .

"I understand why you're such a quiet, stuck up, judgmental bitch." He spanked her left boob, causing her to wail in pleasure-pain. "This hypersensitivity has become your private torment and your deepest kink."

He kneaded her breast more, mercilessly, ignoring all her cries for him to stop. "Because you're so controlled, Ms Katsura, so morally fastidious, every accidental or deliberate touch feels like a sin to you. This makes you overreact every time someone touches you. Heck, you slapped me, remember?"

She moaned, fighting with herself to hold back the pleasure. "Nghh… mhmm… I said I was… ohhhh… I said I was sorry."

"And that overreaction has rewired your brain to pick up senses at a faster, reflexive rate, turning you into a hypersensitive whore without even knowing it."

"No," she shook her head. "That's not true."

Renji squeezed harder to shut her up. "You've been privately craving the moment someone learnt your secret and exploits it mercilessly, haven't you?"

She denied it with a sharp "no" as he pinched her breasts brutally.

"Why are you lying when you keep reacting like the sensory slut you are?"

He rolled her nipples between his fingers, tugging gently at first, then harder, watching her face contort in pleasure.

"Ughhhhhh" Kaori's moans grew louder, uncontrolled, her body arching toward him as if begging for more.

"Yes... no... I don't know!" she cried, confusion warring with bliss in her voice.

But Renji was just starting.

He released her breasts momentarily—drawing a whine of protest from her—then he trailed his hands down her sides, fingers dancing over her ribs, her waist, the flare of her hips.

Everywhere he touched, she reacted: a shiver here, a gasp there, her skin truly was hypersensitive and it showed as he explored her.

He hiked her skirt up completely, bunching it around her waist before tugging it off along with her heels, leaving her utterly naked in the chair, legs spread wide for his—and Miyako's—viewing pleasure.

Miyako knew not to talk, not to make any demands or ask for whatever. Even without any training, she was already a disciplined slut and knew when to speak and when to simply… watch.

From the couch, she watched.

Her breathing grew ragged, her hand working faster inside her pants, eyes locked on what Renji was doing as she wished desperately in her mind that it was her he was doing it to.

She was jealous. So so jealous but she knew not to say anything. Being obedient was the only thing that could get her his cock again.

Renji, meanwhile, was busy.

"Spread those legs wider, Teach," he ordered, kneeling in front of her now, his hands sliding up her inner thighs.

Even though she wanted to fight back, Kaori briskly complied to Renji's order, her thighs quivering, exposing her slick, swollen pussy fully.

Renji's fingers traced the sensitive skin there, avoiding her core at first, teasing the creases where thigh met groin.

She bucked, a high-pitched moan escaping. "Renji! Please... it's too much!"

"Too much? We're just getting started," he taunted, leaning in to blow a cool breath over her clit, making her jolt as if electrocuted.

His tongue followed, a light flick against the bundle of nerves, and Kaori screamed, hands clenching into fists above her head.

The sensory kink was undeniable now.

She couldn't hide it any longer. Not to Renji. Not to Sergeant Miyako. And not to herself.

Every sensation in her body was amplified, her nerves were on fire.

Renji continued to explore.

He bent low and sucked her clit into his mouth while his fingers delved into her folds, stroking the inner walls that clenched greedily around him.

Kaori gasped. Her legs began to tremble like scared beings as she raised her face to the ceiling, moaning out in mad pleasure.

"P—pleaaaseeeee. I can't… take it anymoreeee."

Renji added a third finger, pumping in and out while his other hand roamed her body: pinching a nipple, scratching lightly down her abdomen, even trailing fingers over the soles of her feet, which made her toes curl and another wave of moans spill out.

Kaori was a writhing mess, sweat glistening on her skin, tears of overwhelmed pleasure streaking her cheeks. "I can't... I can't take it! It's too much. I'm feeling it too much …all over my body. Please stawwwppp, Renji. It feels tooooo good. I can't handle it."

But Renji didn't stop. He tongue fucked her pussy as she writhed like a wounded snake.

Her pussy tasted sweet. A clean, faintly floral sweetness, like the first sip of chilled junmai ginjo sake with white peach and a whisper of salted plum skin.

Renji couldn't explain it but it tasted like pure, exquisite pussy.

He tongue-fucked her more and the poor literature teacher could not cope. Her thighs tensed, not in resistance but in overwhelmed surrender; the lightest suction made her hips jerk once, involuntarily, as if a current had been run straight through her spine.

She couldn't stop shivering and vibrating, writhing like a live wire. What was going on with her?

"What is going on with me?" she asked herself, resting her back lifelessly on the chair as he ravaged her pussy. "Why am I enjoying this? You're my student... this is wrong... but... ahh, I don't… want you to stop!"

He pulled back slightly, fingers still buried deep, curling to hit that spot inside her. "That's because you need it, Ms Katsura. Your body's screaming for punishment, for me to claim every sensitive inch of you. Just be a sensory slut and admit it. Every touch makes you wetter."

"Yes! You're right! Renji, I just can't hold it back anymore. I'm so sorry." She squirted around his hand, body convulsing in a shattering orgasm, but he didn't let up, drawing it out until she was sobbing.

Renji suddenly stopped, leaving her confused as she looked up at him, her eyes needy and pleading for his cock.

"You don't have to be sorry, Ms Katsura," he said, unzipping his pants to free his throbbing cock.

He held it in his hand, his thick and veined man meat, thrumming for sex with precum beading at the tip.

He stroked it slowly in front of her face, watching her eyes widen with a mix of horror and hunger.

"But if you want forgiveness, Teach. Then admit you're a sensory slut and beg for it. Beg to suck my cock like the good little teacher whore you are."

Kaori hesitated, mind fracturing under the onslaught, but her body won. She just couldn't hold it anymore. She didn't want to care whether this was right or wrong.

She just wanted Renji Kenshiro, her model student, to use her body as he wished.

Kaori looked up at him with her cold silver eyes turned to horny, deplorable beads of lust and submission. "I'm a sensory slut, Renji. So please... Let me suck your cock. I need it in my mouth. Please."

Renji grinned.
