Professor Rosalyn's Choking Sex Lesson
"Hhk! Hhk! Haaah…!"
"Even with it jammed full you're still loud. Aren't toilets supposed to make nothing but water sounds?"
A massive meat rod slammed in and out of Rosalyn's tiny pussy over and over. It was less sex than outright assault.
The noble cunt that once could barely take a single finger had been broken in by Jisu again and again until it became a custom fit for him alone — so thoroughly remade that his cock now slid home with ease.
"Harder… thrust harder, please… punish Rosalyn's filthy pussy…"
Whispering the filthy words she knew would excite him, Rosalyn crossed her legs in an X over his waist. When his cock drove in she clenched to help it enter; when it withdrew she went slack to ease the piston stroke.
Every time he buried himself to the hilt, her cervix dipped a little lower to kiss the head of his cock in welcome. Even with her consciousness half-gone from a beating hard enough to bruise her belly, her body still moved exactly as it had been trained — working tirelessly to wring the seed from him.
"Kh… after nothing but Silen for so long, having Rosalyn again is gourmet."
Jisu loved taking virgins for more than the physical pleasure. The real thrill was mental. It was the instinct of a man who delighted in leaving black footprints across fresh white snow.
The process of molding an ignorant virgin into his personal rag, and the pure satisfaction of knowing he was her first man — that was why he preferred them.
Rosalyn's pussy, however, had been rigorously educated for years from the moment of her deflowering: a Jisu-custom cunt, a special-order maid's hole trained for the sole purpose of receiving his cock. The tightness, the width of the canal — every measurement had been tailored by Rosalyn herself for him alone.
The raw physical pleasure that pussy delivered put any unopened virgin to shame.
"Am I… more delicious than Lady Silen? Ohg—!"
"Obviously. How could she even compare? Rosalyn's pussy tastes far better than Silen's."
"You said Rosalyn's pussy tastes good… please, just once more — praise it again…"
"Rosalyn's pussy is the most delicious in the world."
People feel superior through comparison. For days she had been locked out of even a kiss, denied all contact while he devoted himself to the difficult training of a new Level 7 slave. That single sentence melted every last scrap of her wounded feelings.
"Hegh… so kind…"
"Were you lonely?"
"A little… yes, Master. You're free to ravage whomever you please, but this training period has been so long. Please… spare a little attention for us too—!"
Moved once more by his tenderness, Rosalyn climaxed, spraying love juice across his stomach. Jisu laughed as if he couldn't believe it, scooped the fluid up with his fingers, and shoved them straight into her mouth.
The moment they entered, Rosalyn sucked them with the reverence of someone handling a priceless treasure. Feeling the warm, clinging caress of her tongue, Jisu drove his cock even deeper.
Her belly rose and fell in tiny surges matching the thrust of his cock, as if something inside were trying to push its way out. He could feel her pulse against the tip of his cock.
"Hehe… I've been completely run through by Master's meat spear…"
"Today I'm going to kill you for real."
"Ha-uuuh… heuuh… if it's by Master's hand, death is welcome anytime…"
"I was joking. Why would I throw away an excellent meat toilet like Rosalyn? I've got to keep using you."
"Hegh… saying something so kind — who are you trying to seduce, heguuh…"
Mid-thrust, Jisu noticed her nipples standing stiff with arousal. He lowered his upper body and took one into his mouth.
"Hnh… that feels so good, Master… more… suck harder…"
Rolling the swollen nipple between his tongue and teeth, he nearly devoured her breast. Even among all the women he had ruined, Rosalyn's firm, soft tits always ranked at the very top — genuine luxury goods.
— Crunch.
"Hnnngh… haaaaah!!! Y-you bit me…"
A bite hard enough to leave teeth marks. She writhed as if in pain, yet every time his teeth sank in she moaned and squirted love juice in little spurts.
Starting at the nipples, Jisu left deep bite marks across the broad expanse of her chest. Leaving his vivid red brands on her canvas-white skin was pure male instinct — but so was the way her pussy clamped down on his cock every time he bit hard.
"I should show off the marks I left to the other maids, shouldn't I?"
"Th-that's right… they're the marks Master specially carved into me…"
"Cast a preservation spell and walk around the estate bare-chested for two days."
"Y-you pervert… haaah… I love you so much, Master…"
"Though I'd like you a little tighter…"
"Kehk! Kkuuh!"
"Khah… that's it, Rosalyn. This is the pussy I wanted."
His hand found her throat and squeezed until the veins stood out on the back of it — past mere breathlessness, cutting off oxygen to the brain entirely, hard enough that survival itself became impossible.
At the same time he sat up, shifting them into a woman-on-top position and forcing her to move.

Even for Rosalyn, a choking session this brutal was rare. As her vision bleached white she thrashed on pure survival instinct, pounding uselessly at his chest — like shouting at a boulder. Nothing came back.
"I'm… dying, Master… I'm dying…"
"Cum and I'll let go. Make yourself cum."
"Ohg! Ohg! Ohg! Ohg! Ohg! Ohg!"
Rosalyn forced strength into her buckling legs and ground herself down on top of him — not for pleasure, but for survival.
"Ohgohgohg! Ohgohg!"
"See? You can do it when you try. Just a little more — I'm about to cum."
Paradoxically, she was experiencing the greatest pleasure of the entire session. When oxygen is cut off, the brain floods itself with endorphins to blunt the agony.
As she worked her hips, Rosalyn's consciousness drifted somewhere far away, floating free.
"Kehek… hek…"
"Open your mouth."
— Slurp, slurp.
Ignoring her resistance, Jisu forced her mouth open with a cold expression and kissed her, mixing their tongues.
Pain, pleasure, and resentment warred across her face, yet her tongue still coiled around his by pure conditioned reflex. Even on the brink of death she acted for her master's pleasure and her own — the perfect model of a thoroughly trained toilet.
Of course the conditioned reflex kicked in: choke her and her pussy clamped down as if trying to murder his cock. The special-order maid's cunt squeezed so hard it felt ready to shear him clean off.
At the same time Jisu rammed himself in until her belly bulged in the exact shape of his cock. Unlike the earlier thrusts that had merely pushed outward, this was a piston stroke that truly churned her guts.
As the pain of her insides being shoved upward and her fading consciousness drained the color from her face, Rosalyn, in a flash of desperate ingenuity, stopped simply rising and falling. She twisted — rotating her hips to grind him.
Her already vice-tight pussy, combined with that spinning motion, caught the head of his cock against her walls and rubbed it raw.
— Schlick-schlick-schlick-schlick!
The change in stimulation made his cock — already on the edge — twitch and prepare to fire.
"Hnn… hnn… hgiit!!!"
"Kh! I'm cumming inside Rosalyn — don't spill a single drop!"
"Haaaaaaaaaaaaaah!!!!!!!!!"
Jisu came inside her, dumping a load of milky white no smaller than his first. While her throat was still crushed she managed, barely, to hold it in.
The moment he released his grip, color flooded back into her face — and the pressure clamping her pussy vanished with it. Seed came surging out of her as if shoved from within.
— Glug.
Perhaps she had clenched too hard: a stream of yellow liquid arced out from between her folds and splattered down. Angry red handprints ringed her throat.
"Didn't you ask me to fill every hole? I packed your pussy full, and you just empty it out?"
"Eguuh…"
"I'm really too nice, aren't I?"
"Euuh…"
While Rosalyn lay unconscious, Jisu plugged the overflow himself, scooping the seed pooled on her thighs and the bed and pushing it back inside her.
Then he took a fixed dildo from behind her and jammed it into her pussy, sealing the hole completely so nothing could leak out.
"What should I do until she wakes…"
Ravaging her whether she was out cold or not had its appeal — but checking on the spectator was fun in its own right.
— Bzzzz.
"Ehek… haah…"
"I was going to give you nothing at all if you didn't do it properly — but when you perform this well, I have no choice but to reward you more."
Jisu turned toward the soft buzz and the moans. There was Silen, panties hooked around one ankle, pressing a vibrator to her pussy. The way her hips lifted at regular intervals suggested she was already climaxing out of sheer habit.
A cloth gagged her mouth; she panted through it, staring at him with hazy eyes. He pulled the cloth free and wiped her face with a towel.
"How was it?"
"…That…"
