Seeing her son's erect penis while he was masturbating, Alice became excited. Even in bed, she couldn't stop thinking about her son's penis, and her hand naturally moved to her crotch to masturbate. Her son, noticing the moans leaking from his mother's bedroom, also witnessed Alice's masturbation, and thus the two became involved in a sexual relationship.
