Ashlyn Peaks, the thick and busty stepdaughter, can't help but flaunt her curves around the house. Her stepdad, Peter Fitzwell, finds it increasingly difficult to resist her charms. One day, Ashlyn decides to take matters into her own hands, literally. She spreads her thick thighs, making her pussy lips glisten as she fingers herself, knowing her stepmom, Vivianne DeSilva, is just a room away. Peter walks in, catching Ashlyn in the act, and the temptation becomes too much. Ashlyn invites him to join, and they engage in a heated, forbidden fuck session, right under Vivianne's nose.
