My wreck of a stepdaughter and the outrageous help of my husband

An 18 year young girl asks out her stepfather and after sending her a text message of, ‘You’re hot looking,’ she wants more of the same from him. He feeds her appetite, leading her through a sensual metamorphosis of a sex-fawning woman. She is his girlfriend but they have a taboo sort of relationship as he continues to test her limits.
