#10 Training Day-1, Dyeing 1
It was late at night—a time when ordinary office workers should already be in bed. For a repeater student whose lifeblood was regulating their biological rhythm, it went without saying.
Normally, Yuchan would have slipped into Nayae's apartment by now, biding his time until she fell asleep. Was this what they called saiōngjima, the vicissitudes of fortune? His leisurely lover's play with her had gone up in smoke forever, but in exchange, he no longer had to trek across town to abuse a fresh, convenient body.
"Hnggg... haaang... ❤"
Nayae lay sprawled on her back like a dog with its belly exposed, prying apart her labia to bare the hood of her clitoris. The tiny rotor in Yuchan's hand targeted the woman's critical spot.
There were two kinds of female orgasm. One came from stimulating the G-spot inside the vagina and the cervix. The other was achieved through clitoral stimulation. Since the clitoris was homologous to the penis, once a peak was reached, arousal plummeted rapidly. Just like with a man's cock, it became hypersensitive right after climax, making even the slightest touch provoke a reflexive hip thrust of rejection—or outright pain.
"Lower your hips."
"Yeees~ B-but... it's too sensitive... ❤ Kyaaah!!"
But with repeated conditioning, he knew it was possible to chain them endlessly, just like orgasms from deep inside the vagina. Nayae was vividly experiencing what it meant for her breath to catch in her throat as she hit peak after brutal peak.
A metal rotor designed solely to assault the clitoris. With its slim rod and minuscule vibrating weight, it could even be slipped behind the skin to strike the clit directly. Orgasmic hell.
If pressed to a glass, its vibration would shatter it in seconds—now zeroing in on Nayae's pinpoint without a millimeter's deviation. Yuchan had teased her clitoris with the rotor for over an hour. The organ, already inexplicably swollen lately, had ballooned to at least double its size from the relentless assault. Like a pearl gleaming from a gaping oyster shell, visible from afar.
"Haaaang... I'm cumming... cumming... cuuuuming... ❤"
Nayae's hips arched like a bow. Her lower body thrust skyward in a bridge pose, thighs fluttering like a suffocating butterfly's wings. Pleasure bordering on abdominal agony—or was it pain masquerading as ecstasy? Distinctions blurred into oblivion. She felt her inner walls contracting wildly.
From Yuchan's observations, Nayae's climaxes typically involved about 35 contractions over 20 seconds, followed by irregular aftershocks—another 20 over the next 50. But her sensitivity, ratcheted to extremes by him, demanded more. Her pussy clenched nearly twice as hard, ripening with thick nectar.
"Nayae."
At his prompting, she answered in a voice frayed to breaking—tiny in volume, the polar opposite of her orgasmic screams.
"N-Nayae's clitoris... haa... has cum... 49 times... ❤"
On the waterproof sheet spread beneath her on the bed rolled at least a cup's worth of her honeyed fluids. Her inner thighs, deep abdominal muscles, even the muscles around her solar plexus for those frantic breaths—all twitched in unfamiliar agony, like cramps from muscles she'd never used. Subjectively, her clit felt like a baseball-sized swelling, a hundred times bulkier. That sensitive. That raw.
Her whole body went limp, melting. Dizzy, on the verge of blackout. All sensations shoved aside save the blazing inferno between her legs.
"You look truly exhausted."
"Y-yes... I-I can't take anymore... hik... "
Yuchan flicked the pearl-sized clitoris with his finger. Even that brief contact sent searing heat surging through her. At this point, he could probably grip it between thumb and forefinger and jerk it up and down like a guy fisting his own cock. Nayae's sharp yelp faded into the background as idle thoughts drifted through his mind.
"Still, I'd like to hit 50. That okay?"
"...Huh? Y-yes... I can do it..."
"Good girl. You're diligent, so you hate half-assed numbers, don't you?"
Panting like a deer snared and dying, Nayae managed a reply. Could she endure more? Her body felt like it was shattering under pleasure's weight. The first orgasms had been tolerable—even welcome, sweeping away the throbbing ache in her lower belly. That was where she usually stopped during solo showers.
But two became three, then ten. Pleasure twisted into torment. Like a honey-slicked dagger stabbing her ovaries. Bliss faded into stark pain. She barely restrained her convulsing body, splaying her pussy wide so he could torture her clit more effectively. That was the worst—taming her bucking flesh like a rodeo bull.
Then, past the double digits, madness bloomed anew. Pleasure on another plane from her old masturbations. Her mind hazed into a meadow bursting with flowering ecstasy, gourmet delights, azure skies and clouds—rolling in euphoric splendor. Pain receded into boundless bliss. Nayae the person dissolved; she became a machine squeezing out climaxes.
And she understood why Yuchan forced her peaks through clitoris alone. Past a certain threshold, her guts quaked insanely. Vaginal nerves she'd barely sensed before beckoned his cock. She craved that massive thing plunging deep, pounding relentlessly. The pitiful female instinct: feel pleasure, crave impregnation for species survival. She even felt her womb descending to welcome seed.
With trembling eyes, Nayae gazed at the bulge straining his pants. How good would it feel buried to the hilt, ravaging her madly? Pinned immobile by his solid build and strength, his glans kissing her cervix as he pumped her full...
Flesh aflame, she'd forgotten her plight—rational thought impossible. Perhaps extreme stress and terror spurred her breeding urge. Weren't there cases of men reflexively ejaculating before death to pass on seed?
"T-Teacher..."
"What is it?"
She meant to beg for penetration, but the words stuck. This was rape. She was being raped. Yet here she was, succumbing to lust, pleading her rapist to claim her front hole? Her last shreds of pride and morals barely choked it back.
"N-nothing."
"Silly. Anyway, for the finale, make Nayae do it by hand. You must be bored of machines."
His stroking hand felt so warm on her head, gently sweeping sweat-matted bangs aside. His scent wafting close dizzied her brain.
"Yes... I'll cum masturbating the clitoris Teacher doubled for me..."
In a dreamy daze, she fumbled her fingers onto her sprout. Realization hit like dread of pulling a fishbone yourself. Impossible. The thickly swollen clit, hood fully retracted, bucked her hips at mere contact. Routine stroking in this state...?
"D-doing it..."
No choice. He was gentle now, but who knew when he'd turn terrifying? Desperate to avoid the worst, she rolled her clit gently between her fingers.
"Hiiik!! My body's... breaking... "
Unlike the rotor's monotonous buzz, her fluid fingers drew out richer depths of climax. Her resident ID card jangled against her breasts as her lithe nudity writhed. Twisting from pleasure's density yet chasing it desperately—adorable.
"C-cumming... gonna cum... Nayae's 50th... hngg... "
Yuchan calmly filmed her finale. Sight long gone, she rolled her eyes frantically, squirting nectar into her depths.
"Haaaa..."
Her shuddering, rigid body collapsed. Jaw slack, mouth agape, she gulped air—stirring raw desire.
"Good work. You did well, Nayae."
"Th-thank youuu... ❤"
Stroking her head, Yuchan scooped her into the tub and meticulously wiped the sheet. His grand plan had shifted, but the details held. He'd stoke her desperation, heighten her sensitivity, craft moments of soul-crushing regret on reflection.
Not "blackmailed into sex." But vivid memory of begging for cock. He'd prime her into heat for it.
Heading to the bathroom, he saw Nayae asleep from orgasmic excess, snoring contentedly in the tub. He roused her.
"You'll catch a cold like this. Open your eyes."
"Not sleeping yet."
Her voice unmistakably awake, eyes snapped open. Nayae's frantic gaze landed on Yuchan's towering, throbbing erection.
"Haa..."
A hot sigh escaped unbidden. Sane for the first time confronting his aroused cock, it shocked her. Easily over 20cm, girth that her thumb and index couldn't encircle. She'd thought it big receiving piss on her face in the toilet, but did cocks really grow this massive? The tip reeked of potent male musk now—he'd leaked pre-cum watching her cum.
He saw her bite her lower lip. Head turning in shame, but eyes locked straight.
Swallowing, she shoved down desire.
"Will Nayae make you feel good?"
"Yes... Nayae's mouth-pussy will serve Teacher's cock."
As if waiting, she parted her lips and slowly engulfed him. Unlike drugged fellatio, she took exquisite care—no teeth grazed; pure bliss enveloped him. Yuchan, stamina king for hours of sex, made an exception tonight. No fucking Nayae. Cock was a luxury until she drowned in aching regret, loathing her own yearning.
Savoring her mouth leisurely for 15 minutes, he neared release and withdrew.
"Aaah..."
Like a kitten nursing, she'd sucked eagerly—now mewling in loss. Unaware, no doubt.
"Palm out."
She obediently cupped her hands. He sprayed hot seed atop them.
"Ack...!"
Thick, copious semen pooled deep—a tiny pond. Eyes rippling strangely, Nayae stared at the pulsing shaft and the warmth spreading over her skin. By now, craving it straight to her womb?
He considered pushing further, but more tonight would backfire. Balance was key: carrot and stick.
"Wh-what should I do with this?"
She tilted her head, faintly puzzled. No trace of tonight's deep terror or feigned composure. Her everyday self? Eerily normal. Brain overloaded from excess?
"Lick it clean."
"Yes, Teacher. Thank you for bestowing your sacred semen."
So performative it bordered on farce. Hesitating, she eyed the pool, then extended her tongue. Up close, his masculine scent maddened her. Salty, bitter Yuchan essence—she lapped it like a cat.
