Custom: I'm your step-mom and I lost a sports bet with you. It's no fair! You know I don't know anything about sports! But since I lost I have to go outside and strip completely naked for you and then slather my body in oil all while you watch. I peel off my shirt, pants and panties and I'm so nervous! What if someone sees us! I'd never hear the end of it. We better make this quick then. I then start pouring the oil on my tits and rub it in, making them look smooth and shiny. Then I pour it on my ass. My butt is so round and tight, and the oil just makes it look even sexier. The more I pour on the oil the more comfortable I'm getting, and the more aroused you get just watching. Soon my curvy MILF body is all slick and sparkling with oil. Finally I decide it's time we went inside before we get caught. Then you playfully grab my clothes and start running off with them. I chase after you, but I'm laughing and giggling the whole time.
