I never planned to tell anyone about what happened between me and my sister, but after years of keeping it locked inside, I need to get it out. It started the summer we were both home from college. I was twenty-one, she was nineteen, and the house felt too small for the tension that had been building since we were teenagers. Our parents were gone for a long weekend, leaving us alone with nothing but old movies, cheap beer, and the kind of silence that makes every glance feel heavier.
We had always been close, but that night the closeness turned into something else. We sat on the couch in the living room, lights low, the TV flickering. She wore an old tank top and shorts, her legs tucked under her. I kept stealing looks at the way the fabric stretched across her chest, the curve of her thighs. She caught me once and didn’t look away. Instead she smiled, slow and knowing.
“You’ve been staring all night,” she said, voice low.
I swallowed. “Sorry.”
“Don’t be.” She shifted closer, her knee brushing mine. “I’ve been staring too.”
That was all it took. My hand found her thigh, fingers sliding up the smooth skin. She leaned in and kissed me, soft at first, then deeper, tongues meeting with a hunger we had both been pretending wasn’t there. Her hand went straight to my lap, rubbing the hard outline through my jeans. I groaned into her mouth and pulled her onto my lap so she straddled me.
We didn’t rush. She rocked against me, grinding slow, letting the friction build. I pushed her tank top up and took one nipple into my mouth, sucking gently while my hands cupped her ass. She moaned my name, the sound raw and real, nothing like the polished stuff in videos. This was our living room, our bodies, the faint smell of her shampoo mixed with sweat.
She stood up long enough to shove her shorts and panties down. I did the same with my jeans. When she climbed back on, she reached between us and guided me inside her. The first push was tight and hot, her pussy gripping every inch. We both froze for a second, breathing hard, realizing there was no going back.
Then she started moving. Slow circles at first, then deeper strokes. I held her hips and thrust up to meet her, skin slapping softly in the quiet room. She leaned forward so her breasts brushed my chest, whispering dirty things she had clearly been thinking for years.
“Fuck, you feel so good inside me. I’ve wanted this for so long.”
I answered by sucking on her neck, leaving a mark I knew she would have to hide later. We changed positions after a while, me on top of her on the couch, legs wrapped around my waist. I went deeper, pounding harder, the wet sounds filling the room. She came first, clenching around me, nails digging into my back as she cried out.
I followed right after, pulling out at the last second and finishing across her stomach, watching the thick ropes land on her skin. We lay there panting, sticky and shaking, neither of us regretting a thing.
That weekend we barely left the house. Every room became a place we claimed. The kitchen counter, the shower, even our parents’ bed one reckless afternoon. We filmed a couple of short clips on her phone, just for us, shaky and unedited, the kind of amateur footage that felt more real than anything online. Her moans, my grunts, the way she looked back at me while I took her from behind, all of it raw and ours.
By Sunday night we had to pretend nothing changed, but we both knew it had. We still hook up when we can, careful and secret, but those first days remain the hottest because they were new and forbidden and completely ours. No script, no audience, just two adults who finally stopped pretending.
