In the dimly lit hallway, the stepsisters' hands explore each other's bodies, their breath heavy with anticipation. The younger one wraps her small hand around her sister's throbbing cock, stroking it gently before taking it into her mouth, her tongue swirling around the head. She alternates between sucking and jerking, her hand working the shaft while she licks and laps at the sensitive underside. The older sister, overcome with lust, pushes her onto her back, spreading her legs wide to reveal her wet, shaved pussy. She fingers her roughly, her thumb pressing down on her clit, making her squirm and moan around the cock in her mouth.
