I had backed up to the wall and she was leaning in toward me, not touching me, but close. She slid her hand down into her bikini, and I could see the top edge of her pubic hair.

“You wanna fuck me?” Her hand moved between her legs.

I groaned, closing my eyes against it. “Dawnie,” I pleaded. “Please. Stop.”

“You want to,” she whispered, and I jumped when she squeezed my crotch. My cock throbbed against her hand through my boxers. “You’ve been wanking in the shed and looking at that girl who looks just like me and wishing it was really me all along, haven’t you?”

She moved her hand between my legs, rubbing it up and down the length of my shaft through the thin material.

I groaned, “Yes. Oh God, Dawn, yes.” I grabbed her hand, pushing it away. “You gotta stop. We really can’t do this.”

She pouted, her brow knitting. “Why not?”

“Because,” I choked. “Because you’re my sister.”

She sighed, moving back and sliding up to sit on the table. She smiled, then, her eyes getting that mischievous glint they used to whenever we were gonna do something we’d get in big trouble for. “Well… what if we don’t touch each other?”

I frowned. “What do you mean?”

She bit her lip, leaning back on the table so she was laying down. I gasped at the sight of her, spread out on the table topless, the bikini bottoms showing the clear outline of her cunt, swollen and thick. God, I wanted to see. My cock was tenting my boxers, and there wasn’t a damned thing I could do about it.

She put her feet up on the table and lifted her hips, sliding the white bikini bottoms down her thighs. Then she spread her legs, and I could see her cunt, shapely and bulbous, the dark hair trimmed. My whole body responded, wanting to climb inside her somehow, bury myself there. My cock knew exactly what it wanted, even if my head was telling me no. She leaned up on one elbow with a smile, using her other hand to reach down and open her lips, showing me the pink inside.
