With the house empty and their parents away, two curious siblings explore the forbidden territory of each other's bodies. The brother, a strapping young man with a cock that's always ready, finds his sister's lustful gaze irresistible. She, a virgin with a hunger she can't suppress, can't help but stare at his massive length. He takes her hand, placing it on his cock, and she strokes him, feeling it harden and pulse. He pushes her down on the bed, spreading her legs, and she gasps as he rubs his cockhead against her wet slit, ready to defile her innocence and claim her as his own.
