You walk past your step-sisters room and see her doing her makeup in a tshirt and underwear. Why is she doing her makeup so late at night? Shes looking extra pretty tonight. She must be trying to sneak out when everyone goes to bed. You decide to sit in her room for a bit and see whats up. Shes extremely annoyed and aggravated that you wont leave. Someone keeps texting her and she gets all giggly. She becomes really bitchy so you stay even longer, you know she is definitely going to sneak out tonight. She finally caves in and tells you she is going on a date tonight and begs you not to tell on her. You get kind of jealous and decide you need to fuck her first before some random guy gets his way with her. You say you wont tell on her if she fucks you. She likes this guy so much and wants to go out so bad she actually does it. Shes pissed off but if thats what it takes she will do it. First you make her put on the dress she is going to wear tonight. She spits on your cock and jerks you off a little. Then she gets on top and slides her pussy onto your dick. Her pussy is so creamy! Then she turns around and bounces up and down your cock. You love looking at your step-sisters ass. She keeps riding you until you give her a huge cream pie. Now that you fucked her first that guy can have your sloppy seconds
