68. Professor and Teaching Assistant, Student 6
The teaching assistant, this 27- or 28-year-old young man, had dragged Su-hui into the bathroom. He sat her down on the edge of the bathtub, her smooth skin still faintly flushed from earlier games.
“Spread your legs, Su-hui.”
“Y-yes… Assistant-nim.”
Su-hui obeyed at once, parting her thighs on the rim of the tub. A thick mess of white semen coated her folds, sticky and glistening in the harsh bathroom light. The teaching assistant twisted the shower knob, letting hot water cascade over her chest first, then lowered the stream between her legs. He took a generous handful of body wash from the bottle on the shelf and began to rub it in slow, deliberate circles across her breasts.
“Huuuung…”
“Still so hard, Su-hui?”
“Aaaah… every time… you touch me…”
Su-hui arched her back, offering her breasts with a playful pout. The assistant’s fingers moved faster, thumbs circling the stiff pink nipples, rolling and pinching them until they stood even more erect.
“Huuut… mmm… ah…”
Su-hui’s small, elegant hand reached behind her, wrapping around the thick cock still half-hard in the assistant’s trousers. The moment her grip tightened, the shaft stiffened further, swelling angrily against her palm. She squeezed and stroked with slow, filthy pumps, her eyes half-lidded in ecstasy. The assistant groaned and slid one hand between her thighs, two fingers sinking straight into her soaked entrance.
“Anh… uhn…”
“Shall I wash you inside too, Su-hui?”
His fingers thrust deeper, rougher, scissoring and pumping while his thumb ground against her clit. Su-hui’s hips jerked; both men’s cocks twitched visibly, shiny and eager. The assistant curled his fingers, finding that sensitive spot inside her and rubbing it relentlessly.
“Haa… it’s all full! Inside.”
“Hiii… uhn… aaaah… Assistant-nim filled me so much…”
“How does it feel when I shoot inside you, Su-hui?”
“Haa… uhn… good… ah… inside… please…”
With every hard stroke the assistant’s fingers pumped, fresh semen spilled from her stretched hole in thick, creamy ropes. Su-hui’s thighs trembled violently, her whole body quivering on the edge.
“Haaak… uhn… aaaah… still too sensitive… huuuh…”
He pulled his fingers free and helped her stand, turning her to face the wall. His hand pressed her palms flat against the cold tiles.
“This side needs cleaning too, doesn’t it?”
Water sprayed again. Two fingers pushed past her tight rear entrance, curling immediately, scraping the sensitive walls. Su-hui gasped, her hips rocking back instinctively. The assistant pumped steadily, watching her creamy juices trickle down her thighs with every thrust.
“Huuu… uhn… ah… uuuht…”
Her slender waist shook. The pleasure was becoming unbearable.
“Feels good, Su-hui? My fingers stretching you?”
“Aaaah… yes… yes… too much… ah… just a little more… please…”
“You’re so sensitive, Su-hui.”
“Haaak… it feels… so… good… just a little more…”
He sped up, fucking her ass harder. A few moments later her legs locked, body convulsing as a clear gush of fluids exploded from her cunt onto the floor.
“Haaak… ah… uhn…”
“Wow… it’s flowing so much.”
“Huuut… uhn… aaaah…”
Her back arched as thick strings of arousal dripped from her swollen lips. The assistant rinsed her ass and pussy again with the showerhead, washing away every trace of mess until both holes glistened pink and clean. A single drop of water slid down her spine, tracing the curve of her perfect ass, the smooth backs of her thighs, and finally her delicate ankles.
He wanted to bury his throbbing cock into any hole available right now, but Professor Choi was waiting. He barely held back.
When they finally stepped out of the bathroom, Professor Choi was already there, waiting like a predator. His large hands seized Su-hui’s body and twisted her arms behind her back, snapping steel handcuffs into place around her slender wrists.
“This time we’ll keep you tied up and use you like a fleshlight, shall we?”
Su-hui was forced to her knees on the bed, wrists cuffed behind her, chest pushed forward. Professor Choi sat on the edge of the mattress right in front of her. He took her chin and guided her mouth to his cock.
“Aaaah…”
Su-hui eagerly sucked, hollowing her cheeks, tongue swirling around the thick shaft. The assistant stood behind her, gripping her ass and rubbing his own cock between her bound wrists, stroking her hands up and down his length. Su-hui’s soft fingers, freed for a moment, moved awkwardly but eagerly, loving the way the shaft felt trapped between them.
“Huuut… ah… aaaah…”
Seminal fluid leaked from the assistant’s cock and coated Su-hui’s hands. She worked it into her palms like lubricant, pumping faster.
“Cjick… cjick…”
Professor Choi leaned back and let her mouth slide down further. She took his thick cock to the back of her throat with no hesitation. The assistant, standing behind her, had a perfect view of her pink, clenching ass. He pulled out of her hands and grabbed her hips, spreading her cheeks wide. The tight rosebud of her anus winked open, begging to be filled.
“Kuu… Su-hui… I’m going in.”
“Huuup… uuuh…”
Su-hui kept sucking Professor Choi’s cock while her hips rolled back in invitation. The assistant slowly pushed forward, sliding his thick shaft into her ass in one smooth glide.
“Huuuuh…”
The new depth made Su-hui’s eyes roll back. She moaned around the professor’s cock, face buried against his abs.
“Haa… good… good…”
“Yes… if you suck so well, I’ll stretch both holes for you.”
“Aaaah… uhn… aaaah…”
The assistant’s cock slid in and out of her ass, the wet sounds filling the room. Su-hui’s pussy grew even wetter, arousal dripping down her thighs.
“Huuung… uhn… ah… aaah…”
“Kuu… Su-hui’s ass is so tight too.”
“Ah… uhn… deeper… please… ah…”
Professor Choi lifted her upper body, pulling her forward until her face was pressed against his chest. He slammed his cock into her dripping cunt in one brutal thrust.
“Haaak… aaaah…”
Now she was impaled on both cocks. The fullness was overwhelming. Her handcuffed hands struggled uselessly behind her back.
“Aaaang… ah… ah… so full… again… huuuuht…”
“Both holes are delicious on you, Su-hui.”
“Ah… uhn… aaaah… please… eat me so much… Professor… haaang…”
The two thick cocks stretched her in opposite directions. Every time she pushed forward, the professor’s cock sank deeper into her cunt; every backward roll sent the assistant’s shaft slamming into her ass. She lost all control, shaking violently between them.
“Ah… aaah… ah… uhh… haaaht…”
“Huhu… I’m going to break you, Su-hui.”
“Aaaah… deeper… please… huuuuht…”
“Shall we change positions?”
Professor Choi pushed her down onto the bed and climbed on top, pinning her beneath him. He pulled out of her pussy and aimed his cock at her ass. The assistant stood behind her again, gripping her hips and forcing her to present her rear hole once more.
“Haaak…”
Su-hui reacted instantly, her body already addicted to the double penetration. She pushed back to take the assistant’s cock again while the professor slammed into her cunt.
“Iya… not even fully stretched yet and it’s already overflowing?”
“Aaaah… uhn… ah… too… too full… huuuung…”
The assistant began to fuck her ass in earnest, his hips snapping. The professor pounded her cunt with equal force.
“Ah… ah… haaang… aaaah… behind… feels… so good…”
“Behind? Where?”
“Haaht… ah… ah… the ass… aaaah… yes… ah… too good…”
Professor Choi’s pace became vicious.
“I can’t let you win just me.”
“Cjick… cjick… cjick…”
His cock pistoned in and out of her dripping cunt. Su-hui’s pussy and ass alternated, each hole gripping the invading shafts in turn.
“Ah… ah… hng… uhn… aaaah… uhn…”
Her whole body shook. The professor pulled out of her cunt just as her pussy squirted violently, a clear jet spraying onto the sheets.
“Haaang… ah… ah… cum… cum… keep… huuuuht…”
“Cjick…”
Another orgasm crashed through her. Her toes curled, body rigid. The assistant and professor didn’t stop. Su-hui’s holes clamped down so tightly the men could barely move.
“Kuu… too tight?”
“Huuuung… ah… keep… keep… haaaang… I’m cumming… huuuuht…”
Su-hui’s body convulsed wildly, back arching as she presented her ass to the assistant. The professor gripped her hair and drove into her mouth. Thick ropes of saliva dripped from her open lips onto his chest. The assistant grabbed her ass and slammed into her rear entrance with brutal force.
“Huuuut… ah… ah… aaaah…”
“Su-hui’s eyes are gone already? Enjoying it?”
“Ah… aaah… yes… yes… haaaang…”
The assistant pulled out of her ass, his cock rock-hard and leaking. He pressed the swollen tip against her rear hole and pushed inside in one long stroke.
“Kuu… Su-hui, I’m cumming.”
“Ah… aaah… inside… fill my guts… huuuht… ah… aaah…”
The assistant’s cock pulsed, shooting thick ropes of cum deep into her ass. When he finally pulled out, Professor Choi flipped her onto her back and slammed into her cunt, fucking her with savage strokes.
“Uhn… ah… huuuung…”
Su-hui’s eyes were completely blank with pleasure. She spread her legs wider and took the cock eagerly, sucking the assistant’s cum-smeared shaft between her lips.
“Huaa… uhn… Assistant-nim… cock… aaaah… tastes so good… ah… uhn… uhn… ah…”
Professor Choi roared and filled her womb, pulsing inside her. Su-hui’s hips kept rolling, milking every drop as she chased another orgasm.
“Haaang… ah… aaaah… deeper… please… ah… cum…”
The professor pulled out and immediately replaced him with the assistant, who took her ass again while Professor Choi returned to her cunt.
“Professor, Su-hui still hasn’t had enough yet, has she?”
“Then… since the student wants it… we’ll have to make her suffer a little more.”
Professor Choi returned with a vibrating dildo. He pressed the thick, silicone shaft against her cum-slicked pussy and pushed it inside.
“This weekend is going to be really long, isn’t it?”
“Huuuut… ah… aaaah…”
The dildo began to vibrate. Su-hui’s legs fell open, body shaking as the toy pounded into her cunt.
“Haa… all weekend… uhn… ah… please… eat my pussy… aaaah…”
“Just the pussy?”
“And the ass too… the ass.”
