Eun-seol's Thigh Lock

Yoon Eun-seol sat on the chair with her legs spread wide. One hand was still tugging her top upward, exposing her navel and the underside of her breasts.

Click. Click.

After snapping a few photos, I stopped and pulled the bottle of lube from my pants. Eun-seol tilted her head.

"Juwan oppa, what are you doing?"

"Huh? Nothing. Just stay like that for a second."

I set the camera down on the desk behind her, dropped my pants, and slicked my cock with lube.

"Juwan oppa?"

"Eun-seol. Just once, okay? You don't mind, right?"

"Hnn… I had a feeling. The photos for Soohyuk were just an excuse, weren't they?"

"Roommates fooling around once… that's fine, isn't it?"

It would be. I'd already seen the item's effect on Ayoung and So-yeon noona. Eun-seol would think the same way.

Then she let out a small laugh.

"Oppa, this might be a little… tough for you."

I smirked to myself. I'll make you moan while thinking about your boyfriend in the army.

Once I was ready, I stepped forward, my cock swaying. Still seated, Eun-seol kept her legs open. I didn't bother removing her dolphin shorts; I simply hooked my fingers into the crotch and pushed the fabric aside.

Her freshly waxed, glistening pussy came into view.

Damn…

The sight alone made me harder. I lined myself up and pressed the head against her entrance. Eun-seol pouted.

"Juwan oppa, you're just going to put it in? No foreplay? I thought you'd at least do what you did with So-yeon unni…"

"We're short on time."

I pushed straight in.

Schllk.

At that exact moment, I felt her powerful thighs shift. Her hands gripped the armrests of the chair, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠and her legs wrapped around my waist in one smooth motion.

What the—?

Before I knew it, her smooth, tanned legs were locked behind my back. The thick, caramel-colored thighs squeezed my waist.

Schllk.

Her ankles crossed and tightened. I looked up. Eun-seol's sharp, double-lidded eyes met mine, a playful smile on her healthy, tanned face.

"I told you, oppa. This might be a little tough."

"Tough? It's all the same in the end—ngh!"

Crack.

Her legs suddenly clamped down like a belt, yanking me deep inside her. The moment she loosened her grip, my cock slid halfway out on its own.

Huh?

Eun-seol giggled.

Schllk. Schllk. Schllk. Schllk.

Her thighs began a relentless rhythm—pulling me in, releasing, pulling again. Every time she squeezed, her pussy clenched around me as well, milking me with tight, rhythmic pulses.

"Hah… hah… hah…"

"Haa… oppa… you're pretty big… Soohyuk never went this deep… haa…"

Her lower body moved like a living machine designed to wring me dry. The pleasure was so intense my face twisted. Eun-seol watched with obvious delight, her smile never fading as she continued to work my hips with her legs.

Schllk. Schllk. Schllk. Schllk.

Just when I felt myself nearing the edge, her legs suddenly relaxed.

"Huu… oppa."

"Hah… yeah?"

Her thighs still rested around my waist, but the pressure was gone. She looked at my strained expression and spoke in a casual tone.

"Oppa… my ankles are pretty thin, right?"

"Huh? …Yeah."

Now that she mentioned it, her ankles were slender. Combined with those thick thighs, the contrast was striking.

"You know what they say about girls with thin ankles?" she continued, voice light. "They're supposed to have really good pussies."

"…What? Why?"

"The thinner the ankles, the more they have to tense their pussy to support their weight while walking. So it naturally gets tighter."

"R-really?"

Her playful smile deepened.

"Want to check if it's true?"

Before I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠could answer, her legs snapped tight again.

Crack.

Schllk. Schllk. Schllk. Schllk.

"Hah… hah… hah…"

"Haa… oppa… hold it in… haa… if you last longer than Soohyuk, I'll praise you…"

She controlled the pace perfectly—tightening when I was close, loosening just enough to keep me ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠from finishing. I was forced to keep thrusting under her command, denied release until she allowed it.

Finally, when I couldn't hold back any longer, her legs clamped down hard.

Spurt.

After I came, I slowly pulled out. Thick white cum leaked from her pink folds, trailing down between her spread, tanned thighs.

Eun-seol was still breathing hard, but her lips curved in that same mischievous smile.

"Haa… haa… haa…"

"Haaa… oppa… haa… you're pretty good… huu…"

I dropped to my knees on the dorm floor, gasping for air. My whole body felt drained.

"How was it, oppa? Haa… I told you it would be tough, right?"

Her relaxed voice made something in my chest burn. Then I noticed the timer in the corner of my vision.

"Cutting it close…"

I looked up at Eun-seol.

"One more time."

"Hmm… I was already going easy on you earlier, oppa."

Even after squeezing every drop out of me, she still claimed she'd been lenient. Unbelievable. But I had one last card to play.

I pulled the cylindrical can from my pocket—the Itch Spray. Without turning around, I aimed it between her legs and sprayed.

Psst. Psst. Psst.

Her pussy was still dripping with my cum, the liquid splattering onto the chair and floor.

That should be enough.

Eun-seol's teasing voice drifted over.

"Oppa~ ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I could make you pass out if I wanted. I really was going easy earlier."

I pressed the nozzle harder, drenching her thoroughly.

Psst. Psst. Psst. Psst.

Once I was satisfied, I set the can aside and grinned.

"Eun-seol. I'll make you come in ten minutes."

"Pfft. Go ahead and try, oppa."

I lined up and thrust in hard.

Thrust. Thrust. Thrust. Thrust. Thrust.

"Hnnng~! Haa~! Haaang!"

Her reaction was completely different this time. Her legs didn't wrap around me; instead they spread wide, toes curling tight. Every time I slammed in, her thighs trembled violently.

Thrust. Thrust. Thrust. Thrust. Thrust.

"Aah~! Haaang~! Haaang!"

Her eyes fluttered, half-lidded, lost in the sudden overwhelming pleasure.

Thrust. Thrust. Thrust. Thrust. Thrust.

"Hah… Eun-seol… does it feel good?"

"Hnnng~! It feels… so good! Haa… harder! Hnn~! Oppa!"

She begged for more. I gave it to her, pounding relentlessly. Her athletic body arched and shook beneath me.

Suddenly her legs snapped around my waist again.

Crack.

Thrust. Thrust. Thrust. Thrust. Thrust.

"Haa… more… give me more… haaang! Harder… hnnng!"

Sweat glistened on her skin. Her eyes were squeezed shut, face flushed crimson as she clung to me with arms and legs alike. When her climax hit, she pulled me into a tight embrace.

Spurt.

We stayed locked together, both of us panting. After a while, Eun-seol's voice came out soft and eager.

"Juwan oppa…"

"Yeah…"

"Let's do it one more time."

"…Huh?"

"It felt amazing. One more time."

Even after the intense spray, she was already asking for another round. Her stamina was ridiculous.

A sudden wave of drowsiness hit me. Eun-seol's eyes fluttered shut in my arms. So-yeon noona was already asleep at her desk, and Ayoung was dozing on the bed. I couldn't fight it either.

When I opened my eyes again, everything had returned to normal. Taeyoung was sitting at his desk, gaming like always. It felt as if nothing had happened.

Yet the effects lingered. From time to time, I received messages from Eun-seol and So-yeon noona. They called me late at night to chat or ask for advice, even though I'd never given them my number. Whenever we crossed paths on campus, they greeted me warmly, like close friends.

Even Ayoung started calling me "Juwan sunbae," and I naturally began calling her "Ayoung-ah."
