Her stepson's college friends call stepmommy to ask for help doing a college project (experiment). Stepmommy is delighted! It reminds him of his student days and makes him very happy to be able to help them! The four students and their stepson arrive home this afternoon and I get a number of disturbing ideas where stepmommy will be their guinea pig to experiment with. They will make her undress, spank her, break her ass into four, spread her legs until they are tired for them, with their eagerness to see her tied up, they will very savagely insert a big Fuckmachine inside her tight and sweet stepmommy's pussy... Get your cock ready, you will masturbate to the point of exhaustion with the occurrences of five students and the innocence of stepmommy!
