Chapter 7: I never thought I would be whining and begging my sister

She lifted my chin and kissed me, her tongue invading my mouth. The intense stimulation overwhelmed my senses.

“Hnnn… My… body…” I stammered.

She chuckled, stroking my hair. Even such a light touch sent shivers down my spine.

“So you’re sensitive here, too, Yunha?”
“N-No…”

She laughed, amused by my reaction, and started undressing me. The removal of my clothes heightened the sensations, making me flinch.

“You find even this arousing? Your mind might be male, Yunha, but your body is definitely female.”
“No… I… I’m a man…”
“Are you? This says otherwise.”

She trailed her fingers near my core, teasingly close.

I squirmed, squeezing my eyes shut.

“Ah… S-Sister… Stop… It’s… too much…”
“Unni. I’d stop if you were a good girl and called me Unni…”

Even now, she’s obsessed with that.

She continued her torment, circling my most sensitive area. Moans escaped my lips, impossible to contain.

“Hnn… Ah…”
“You like it when I touch you here, Yunha?” she purred, focusing her attention on that one spot.

“Ahh…!”
“Yunha, just say Unni, and I’ll stop.”
“N-No…!”
“Then endure it,” she whispered, and—

–Thrust

“—-! W-Wait…!”

She pushed a finger inside me. The sudden, intense pleasure sent me over the edge, my hips bucking uncontrollably.

“Hee hee~ You’re a real woman now, Yunha.”

My body convulsed, then went limp. She picked me up and carried me to my bedroom, tossing me onto the bed.

“W-What… are you going to do…?” I asked, dazed.

Her smile turned predatory. “Dinner is served~”
“W-What…?”

I didn’t know then. I didn’t know I’d be begging her, crying out her name.

“…”

The aphrodisiac wore off. The deed was done. Night had fallen. It had been afternoon just moments ago. Parts of the encounter were hazy. How long did that last? I huddled under the covers, glaring at my sister. She approached, a tender look on her face.

“Yunha, admit it, you enjoyed it.”
“…Shut up.”

It wasn’t that I hadn’t enjoyed it. It was the fact that she’d manipulated me that angered me. I hadn’t… fallen. It was the drug. Yes, the drug was to blame for my cries and pleas.

I noticed scratches on her naked body. Did she…?

“Um… Sister…? Did we…?”
“Yes, we did.”

My face burned. I burrowed deeper under the covers. Not only girl-on-girl, but incest, too. It was scandalous. I would never listen to her again. Never.
