#14 Lilium Casablanca (5)
Like most buildings, Cheonsanggye Self-Study Repeat Academy had more than one emergency exit. One by the elevator, two in the study rooms where students crammed, and another right in front of Yuchan's counseling office tucked away in the corner. Students occasionally used the stairs by the elevator for exercise, but no one touched the emergency stairs in front of the counseling office in the most remote spot. Most floors from the first to the rooftop were locked. That made it a far better spot for secret rendezvous than the counseling office, where someone could barge in at any moment.
Yuchan followed Nayae inside and immediately locked the emergency exit door behind them. The academy occupied the 8th and 9th floors of a 10-story building. The 10th floor used to house a pediatric clinic that had gone bust and now stood empty. No one could come from above or below.
A few steps up the stairs, Nayae stood waiting between the 9th and 10th floors.
"Teacher, why were you so late today?"
"I had a little business to take care of."
Nayae's voice carried a slightly sulky edge. Right after the TA session ended, she'd spent the full lunch hour handling Yuchan's semen. She used to bring a packed lunch, eat quickly, and dive straight back into studying without a break. Now she came looking for his cock first. Her already fragile mind had been thoroughly scrambled, breeding a dependency on Yuchan. To quell that anxiety, his cock had become essential.
When he had time, he'd let her leave the academy early and fuck her senseless at her place. Whenever the mood struck, he could summon her to his home at night for service. No one would ever guess that Nayae, the epitome of a diligent model student, was showing up late because of sex. Yuchan took immense pride in being the one who'd corrupted her.
"I was waiting for so long..."
Ever since that day, Nayae had been diligently taking her oral contraceptives. Not really for her sake—he just couldn't fuck her during her period. They could mess with her hormones and make her sick, so they were one of the drugs repeaters should avoid unless exams were imminent, but Yuchan had no intention of worrying about that. Nayae herself was thrilled at no longer having a week out of every month off-limits for sex.
"Take off your clothes. Time for inspection today."
He grabbed her arm and led her up to the rooftop stairs. Just in case any noise leaked out.
Once they reached the rooftop stairs, Nayae readily unzipped her hoodie. As Yuchan's sex slave, she'd been ordered to wear only a sleeveless tee and hoodie on top—softcore exposure play. She draped the hoodie over the stair railing, revealing her luscious breasts propping up the tee. The shirt was several sizes too big, so any shift in posture let her huge tits spill out through the gaps. At first, she'd been mortified at dressing like such a slut under her hoodie, but now she wore it to the academy as if it were normal. He'd have to arrange something else for summer, but for now, this satisfied him. He'd confiscated all her bras. Shaping those tits nicely only mattered up to age 17 or so during growth spurts. For a mere toy like her, a bra was a luxury.
"I was imagining you pounding me deep, Teacher, and waiting... that's so mean."
He stripped off her mom jeans, revealing her lower half brimming with erotic allure. Unlike a bra—which she only needed to cover her nipples—panties were essential for hygiene and vaginal secretions. So he'd left those alone. Instead, he picked out every pair she wore: trashy things no woman but a whore would touch.
"I wore this one today."
Blushing, Nayae lifted the hem of her long shirt to show her panties. She stood three steps up, right at eye level. A thin strip of fabric barely covered her pussy entrance, with just strings around her hips and ass. She spun around flauntingly, her plump, firm cheeks digging slightly into the elastic.
Yuchan reached out and groped her ass. No matter how many times, that taut bounce never got old. Nayae shyly arched her back to make it easier for him.
"Good girl. Looks like Nayae's finally getting used to it."
"Hehe, how happy am I to be Teacher's cum dump every single day."
He untied the knot near her hip bone, and the panties slipped easily down her thighs. Her pussy, still arched back, came into clear view. Nayae grabbed her cheeks and spread them wide for closer inspection. Her tattooed mound had fully settled in color after time. In the slit, the hole he'd been stuffing almost daily winked open. Just showing it off had her wet; the thick feminine musk wafted up. No, this was more than just wet.
He knew her physiological responses inside out by now.
"Sorry, but we're finishing with your mouth today."
"Huh? Why... I already took off my clothes."
Her face fell; she'd been sure he'd use her. She'd been counting down to this all through studying.
"Nayae masturbated behind my back again."
"I didn't..."
Her voice wavered unsteadily, even as she held her cheeks spread. It took her just three seconds to crack.
"I did... haang... ♥"
Yuchan wiped his fingers thoroughly with a wet wipe and slid them into her hole. Hot, slimy with juices all the way inside. Nayae let out a tiny sigh, clenching delicately around his thick fingers to savor them. Her sensitivity training was complete—legs buckling at this alone. Women's bodies amplified pleasure the more and better you used them, unlike men's. On a scale of 1 to 100, Nayae was pushing 90 now.
"Why lie?"
He added a second finger, gently scraping the bulging G-spot just inside her entrance. Nayae melted into a whimpering reply.
"Haang... If I admit to masturbating... you won't give me your cock... sorry..."
"When, how many times, what were you thinking?"
He relentlessly teased her pleasure spot, matching her instinctive ass wiggles. Her pale pink clit, swollen like a tiny fruit on a stem, glistened with dew-like slick.
"Today... three times this morning at home... thinking of the first time... haeut... ♥ you raped me... I shoved three fingers in hard..."
All his efforts to enlarge it had plateaued at 1.1 cm. Human flesh had limits without surgery.
"And during break... hick... secretly in the girls' bathroom... rubbing my clit... to you using Nayae's face as a toilet... haaaang... ♥"
The squelching grew louder, her voice pitching higher.
"Heek... I'm... gonna cum..."
Yuchan pulled his hand away right on cue.
"Orgasms are a luxury for a slave who fucks her pussy without her master's permission."
"Ah... aaah..."
Nayae sighed in aching frustration.
"Sorry... but thinking of you, I couldn't hold back."
It was praise-worthy, but Yuchan had no plans to indulge her bad habits further. You didn't feed a pet that raided its own food bowl.
"Anyway, just your mouth today."
"...Teacher... sorry... Nayae will shake her ass hard, so please stuff your cock in my cum bucket at lunch too..."
Still spreading her pussy, she wiggled her hips seductively. He'd trained her with carrot and stick, but now the stick was losing effect—hence this cheeky display. Hell, she loved actual whippings. He'd let her get too spoiled. Time for proper education.
Yuchan raised his hand high and smacked her spread-open pussy with both palms.
-Splaaat!
"Kyaa!"
She muffled her scream instinctively—it wasn't too loud. But her legs buckled with the wet rag slap, juices splashing everywhere like water under a rod.
"Ah... it hurts... Teacher."
"Ass up, pussy spread."
Nayae shakily stood and resumed position, movements sluggish and fearful of another smash.
-Splaaat!
"Haaeut...!!!"
Braced for it, her cry was smaller, laced with sweet sighs. Yuchan eyed her pussy: twice as soaked as before. He half-worried about dehydration.
"Kuuuuk... ♥"
"Nayae, when did you get so bold as to demand sex from your teacher?"
"Th-that's not..."
"You're just a replaceable cum rag. Climbing back after a few days of kindness?"
"Ah... no, Teacher... I was wrong..."
Under his scolding, Nayae trembled—not just from fear. Both knew that. Insulting words, corporal punishment, submission. She'd been perfectly conditioned to crave pleasure from it. Otherwise, no matter how horny, she'd have fled his cruelty.
"Sorry... for shaking my ass and begging for cock... sorry..."
These past days, she'd apologized more than in her whole life, thoroughly tamed. Just saying "sorry" now gave her a mild masturbation-like thrill.
"Lie to me or disobey once more, and I'll give Nayae the most unimaginable, horrific punishment."
Before, she'd have feared the threat. Now, she anticipated it first. No big thrill otherwise. She just adored Yuchan and the pleasure he gave endlessly. For that sweet reward, she'd do anything.
"Now come suck my cock. That's lunch today."
"Yes, Teacher. Thank you."
Only 20 minutes left anyway. Better make her finish him quick, no holding back. Stripped to her sleeveless tee, Nayae knelt before Yuchan leaning against the wall. Lately, he made her kneel often for doggy or irrumatio deepthroats—bruises now dotted her once-pristine knees. At swim practice, did she wonder what others imagined seeing them...? Lewd thoughts like that amused her, but summer's exposure would make it risky. Time to be careful.
Demurely, she placed both hands on her knees and undid Yuchan's belt with just lips and tongue. No hands allowed when servicing his cock with her mouth hole—that was the rule. Expertly, she unzipped his jeans with her teeth, then fished out his half-hard cock through the panties' fly with her lips. What fit snugly before hardened instantly into a baseball bat. Like opening a Christmas present as a kid—this was Nayae's heart-pounding peak. His thick musk through the fabric, the firmness against cheek and lips. She wanted it inside now. Eyes watering, Nayae slowly licked up his shaft from the base.
