In the dim light of the living room, a brother and sister, under the guise of watching a movie, let their hands wander. The sister, her breath hitching, slides her hand beneath her pajama shorts, her fingers finding her clit. Her brother, trying to hide his erection, mirrors her action, his hand moving up and down his length. Their eyes meet, filled with a mix of guilt and desire. As they quicken their pace, their bodies tensing with impending release, a sudden knock at the door breaks the spell, leaving them both breathless and embarrassed, their secret moment interrupted.
