Parallel World: Dahyun's Estrus (8)

"Haa... haah... haa..."

"Haa... haaang..."

In Kang Dahyun's one-room apartment near the main gate of Nuri University, only the sound of our breathing filled the quiet space. We hadn't even taken a single step past the entrance where we'd kicked off our shoes. Dahyun lay on her back, her legs stretched straight up toward the ceiling, completely bare.

From the side, her position looked like the letter "L." I held both her ankles in my hands, her smooth, tanned legs extended beautifully upward. Not a single blemish marred her flawless skin. Her slender ankles and calves were lovely, but the real draw was the firm thighs and the shyly exposed slit between them. Traces of the semen I'd pumped into her earlier still glistened below her entrance.

Anyone who saw those beautiful tanned legs and her exposed sex would instantly get rock hard. I was no exception. My cock stood at full attention, already knowing exactly where it belonged.

Dahyun's face was hidden behind her raised legs. I tilted my head slightly to the side and our eyes met. Her cheeks were flushed deep red from the heat. She didn't look annoyed or irritated like before, nor did she wear that playful expression from when she'd been stroking me. Instead, with her legs held back and her body pinned beneath me, she looked a little shy... and expectant.

In a much softer, breathier voice than before, she whispered, "What are you doing, idiot... Do I really have to tell you every single thing?"

"Haa..."

Her whispered words sent a strange thrill through me. I still held her legs. Those long, smooth, tanned limbs pointed straight up, her slick, exposed pussy framed between her thighs. I pulled her legs toward me, hugging them against my chest like a lover, then guided my cock gently into her waiting entrance.

-Squelch.

She was already soaked, as if she'd been waiting for me. The vivid sensation of her tight, wet heat made my eyes flutter shut.

"Haa... haa..."

-Rustle. Rustle.

I opened my eyes at the sound and saw Dahyun tugging her top off while still lying on her back. Her leather jacket and cotton tee ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠were already tossed beside her head. The black lace bra that matched her panties came next; she struggled for a moment, reaching behind her back, the motion making her body arch ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠enticingly. Soon the bra joined the rest of her clothes.

Her full breasts came into view—smooth, caramel-colored mounds topped with pretty pink nipples. Still holding her legs with my left arm, I reached out with my right hand and cupped one soft breast. The movement brought my upper body forward, pressing her legs even closer to her.

Her firm, silky thighs in my left hand. Her soft, yielding breast in my right. While I explored her body, her voice reached my ears again.

"Haa... move... you idiot..."

At her command, my hips began to thrust.

-Plap. Plap. Plap. Plap. Plap. Plap. Plap. Plap.

The sound of my hips slapping against her firm thighs filled the room. Earlier she'd played with my cock like an instrument; now I was the one playing her.

"Haa... haaang... hngh... haa..."

Her moans began to spill out in time with each thrust. Without thinking, I asked a pointless question.

"Haa... does it feel good?... haa..."

"Haaang... good... it feels good... hngh..."

The way she said "good" sounded far lewder than her actual moans. This was a completely different Dahyun from the sharp-tongued girl who'd teased me earlier or snapped at me outside the dorm. In heat, she seemed much more obedient the moment my cock was inside her. I remembered how she'd only been able to moan like an animal when I took her against the door, and how her legs had trembled after each orgasm.

Feeling a strange sense of conquest, I asked again.

"Haa... really... haa... does it feel good?..."

"Hngh! Shit... haa... you stupid bastard... haa... I already said... it feels good..."

I regretted asking. But once her irritation started, it didn't stop easily.

"Haah... haah... haah..."

"Haang! You... fucking idiot... haaang... shut your mouth... and just move your hips... haaang! You useless bastard..."

Following her order, I closed my mouth and focused on thrusting. My right hand kneaded her soft breast while my left arm hugged her legs. Every time I drove in, her ankle brushed against my cheek.

Even so, her scolding didn't stop.

"Hngh! You... stupid... hngh! The only thing... you're good for... aahng~! is that big cock of yours... hngh! You fucking moron..."

"...So my cock is useful?"

"Ugh... yeah..."

Her pussy was hot, wet, and incredibly tight, squeezing me with every thrust. Her words were sharp, but soon only moans escaped her lips.

"Haah... haah... haah... haah..."

"Hngh! Haang! Hngh! Aahng!"

Her moans grew louder, just like when we'd fucked against the door. Each time I pulled out, clear fluids squirted from her entrance. She'd already soaked the shoes by the door earlier, yet she still had more to give. Dahyun was definitely a girl who got very wet.

Her legs began to tremble in my arms. I'd thought she'd calmed down a little after taking her pants off, but once we started again, the spasms returned. I watched her beautiful tanned legs shake in my embrace.

"Haa... haa... hngh..."

"Haang! Hngh! Hngh! Aahng!"

Those long, tanned legs I'd secretly admired in class were now wrapped in my arms. Healthy color, firm yet soft to the touch, carrying a faint sweet scent—they were perfect. Perfect for modeling, perfect for sex. The very legs that had drawn so many stares were now showing off their curves just for me.

I stroked them like a prized instrument while continuing to thrust. Her legs twitched in response to my cock driving deep inside her.

Her breathing grew more ragged. I could tell she was close. Girls in heat seemed to reach orgasm much faster than usual. Her eyes were trembling at the corners. I tried to delay her climax a little—pinching her nipple with my right hand, squeezing her legs tighter with my left—but she was already lost in the pleasure between her thighs.

"Haa... haa... haah..."

"Aahng! Hngh! Hngh! Aahng! Aahng~!"

Dahyun's eyes were closed now, fully savoring the approaching orgasm. Her lips were parted, her tongue faintly visible between them. Sweat beaded on her skin as her body twitched around my cock. Without thinking, I leaned down and licked her ankle.

-Lick.

It tasted faintly salty from the sweat, but her skin was soft. I kept thrusting while licking along her ankle and calf.

"Haaak... haa... haah..."

"Aahng! Hngh! Hngh! Aahng! Hngh!"

Maybe because she'd teased me earlier, I was also nearing my limit fast. Her pussy squeezed and massaged every inch of me. When I glanced to the side, the system timer appeared.

"Time's almost up..."

Feeling a twinge of regret, I squeezed her breast hard and came deep inside her.

-Spurt. Spurt.

"Haa... haa... haa..."

"Hngh... hngh..."

Dahyun's chest rose and fell with each heavy breath. After catching her breath for a while, she suddenly called out to me.

"Haa... hey..."

"Yeah?"

She was still lying on her back with her legs held by me, looking up with flushed cheeks. A mischievous smile spread across her face.

"Haa... I told you I'd delete the video if you listened to me today, right?"

"Yeah... you did..."

I'd almost forgotten. Right—I'd come here because she threatened to spread that gangbang video. I'd been blackmailed into having sex with her. In the heat of the moment, I'd completely forgotten about the threat.

"I wasn't even thinking about it..."

After all, this was just a parallel world I'd leave once the timer ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠ran out. My reputation here didn't matter. But Dahyun spoke with complete confidence, as if she'd gained some huge leverage over me.

"Haang... On second thought~ I think I'll keep it. Haa... With this video... haa... I'll call you over whenever I want and fuck you senseless."

She wore an expression like she was delivering a death sentence.

"That works for me... I wonder if I'll even come back here again?"

I wasn't sure if I'd ever return to a world with estrus cycles. While I was thinking, the quest timer finally reached its end.

-Flash.

A brilliant white light filled my vision as the parallel world quest ended. When the light faded, I was back in my dorm room, lying in bed under the covers.

A reward window appeared in front of me as I lay in bed.

"...What should I pick? I've got quite a few points saved up, so maybe I should go for something better than just a random box..."

With 25 points accumulated, I wanted something useful rather than wasting points on random boxes. My eyes landed on the Perverse Stamp and the Quest Restriction Area Unlock options.

"Asphyxiation... huh..."

The word "asphyxiation" felt a little dangerous. Without thinking too deeply, I tapped the second option.

-Beep.

"Ugh... I should get some sleep."

Whenever I returned from a parallel world, my body was clean—no sweat, no fluids. Spending the weekend sleeping in sounded pretty good. Remembering Dahyun's beautiful legs wrapped around me, I drifted off to sleep.
