You and your step-mum are having your annual fourth of July backyard barbecue with all of the neighbours. Since you and step-Mom moved to England over a decade ago, this is your one American tradition you keep up. You are really sad though and hiding off in the house, instead of having all of the barbecue fun because some of your friends have made some pretty rude comments about your American step-mothers fat ass. They keep calling it an American bum and it really makes you mad. Step-Mummy comforts you and tells you not to worry about it, she loves having a big fat American ass and showing it off. Step-Mom stands up and shows after American flag trousers, bouncing her big ass in them, and making her big boy's cock stiff as fuck! Your step-mother notices that your cock is hard and she has a wickedly delicious idea: step-mummy is going to make you jerk off to her big fat American ass to reprogram you from feeling shame and sadness when your friends mention how fat it is. Step-Mummy pulls down her American flag trousers and exposes her huge fat white American ass and encourages you her young step-son to pump to step-mummy‘s fat, jiggly bouncing clapping ass. Step-Mummy demands that you come on her bare asshole, so she can pull up her American flag trousers and feel your sticky load in them all day. Hurry up though, you don’t want to miss out on all of the party do you step-son?
