Jillene Mercer, her heart pounding, pushes her brother against the closet wall. She's clad in a thin nightgown, her nipples hard against the fabric. He's in boxers, his cock straining against the material. She reaches out, touching him, feeling him pulse at her touch. He's scared, but she's determined, sliding her nightgown up and guiding his cock towards her wet, aching pussy. She's about to impale herself when they hear footsteps approaching. They freeze, their eyes wide, breath held, as the door handle turns, their forbidden moment interrupted, leaving them breathless and wanting.
