Lily Introduce You to Her Niece Marilyn

One day Lily asked you for a favor, "I have a niece who is very plain-looking and keeps scaring off boys. I want you to teach her the joys of being a woman to make her feel better."

"Alright." You agreed to have sex with Lily's homely niece as a favor. You're shocked when you actually meet her. Marilyn is drop-dead gorgeous!
