The elevator doors close, sealing in two siblings with a mutual secret. The brother, emboldened by the late hour and the empty building, reaches out, tracing his sister's spine, making her shiver. She turns, her eyes meeting his, and the tension snaps. They crash together, their bodies pressing urgently, hands seeking skin, breaths coming in ragged gasps. The elevator jolts, and they stumble, laughing, their eyes locked. The game continues, their bodies intertwined, until the elevator reaches their destination, leaving them craving more than just a stolen moment.
