I never planned to tell anyone about what happened between me and my sister, but the memory burns so hot that keeping it locked inside feels impossible. It started on a humid summer night when our parents were away at a conference, leaving the big house to just the two of us. Lena was twenty-two, home from her first year of grad school, and I had just turned twenty-one. We had always been close, but that closeness had started to twist into something heavier in the months before, with lingering glances and accidental touches that neither of us pulled away from fast enough.
We were in the den, the only light coming from the flickering TV screen. Lena wore a thin tank top and shorts that barely covered anything. Her skin glowed with the heat, and every time she shifted on the couch, the fabric rode higher on her thighs. We had been drinking wine, talking about nothing and everything, when the conversation turned to old crushes and secret fantasies. Her voice dropped low as she admitted she had always wondered what it would feel like to be touched by someone who knew her completely.
I should have laughed it off. Instead, I reached over and brushed a strand of hair from her cheek. Her eyes met mine, dark and steady, and she leaned in. The first kiss was soft, almost hesitant, but it quickly turned hungry. Her lips parted under mine, and her tongue slid against my own with a desperation that matched the sudden ache in my cock. We broke apart breathing hard, both knowing we had crossed a line, yet neither of us wanted to stop.
Lena stood and took my hand, leading me upstairs to her old bedroom. The bed was still covered in the same pale sheets from her high-school days. She pulled her tank top over her head, revealing full breasts with tight pink nipples already pebbled. I stripped off my shirt and jeans, my erection straining against my boxers. She knelt in front of me, tugging the fabric down, and took me into her mouth without a word.
The wet heat of her tongue circling the head made my knees buckle. She sucked slowly at first, then deeper, her hand stroking the base while her eyes stayed locked on mine.
I pulled her up and laid her on the bed, peeling off her shorts and panties. Her pussy was smooth and glistening, the scent of her arousal thick in the air. I spread her legs and lowered my mouth to her, licking long, slow strokes from her entrance up to her swollen clit. Lena moaned, fingers twisting in my hair, hips rocking against my face. I sucked on her clit, sliding two fingers inside her tight heat, feeling her walls clench around them. She came with a sharp cry, thighs trembling against my cheeks.
She reached for me then, guiding my cock to her slick opening. I pushed in slowly, savoring every inch as her body stretched around me. The sensation was overwhelming—hot, tight, and wrong in the most addictive way. We moved together in a steady rhythm, her legs wrapped around my waist, nails digging into my back. Each thrust brought a wet sound that filled the room, mixing with our heavy breathing and whispered names.
Lena rolled us so she was on top, riding me with deliberate rolls of her hips. Her breasts bounced with every movement, and I reached up to pinch her nipples, making her gasp and grind harder. She leaned down to kiss me, tasting herself on my tongue, and whispered how good it felt to finally have me inside her. The taboo of it only heightened every sensation, pushing us both closer to the edge.
I flipped her onto her stomach and entered her from behind, gripping her hips as I drove deeper. The angle let me hit the spot that made her moan into the pillow. I reached around to rub her clit in tight circles while I fucked her, feeling her second orgasm build. When she came again, her pussy pulsing around my cock, I followed right after, spilling deep inside her with a groan that seemed to come from my soul.
We collapsed together, sweaty and trembling. In the quiet that followed, Lena turned to face me, her expression soft but certain. We both knew this was only the beginning of a secret we would carry together, one that felt too good to ever let go.
