Under the cloak of night, two siblings, Johnson1125, share a secret. In the cramped attic, they huddle close, their bodies brushing. The girl, her breath hitching, tentatively reaches out, tracing the outline of her brother's hardening cock through his pajamas. He shudders, his own hand snaking up her thigh, pushing her nightgown up to reveal her bare, damp pussy. They move in sync, fingers exploring, breaths mingling, until they're both panting, their bodies slick with sweat and desire. They're close, so close, when suddenly, a floorboard creaks below. They freeze, hearts pounding, their secret moment shattered.
