She sits you down, makes you take off your pants, and bend over while she 'explains' her house rules by spanking you with each one. She wants you to learn your lesson BEFORE breaking the rules, so she implements a punishment right away... and more where that came from! When her boyfriend arrives, she's going to be busy fucking him all day, in every room. And why should she clean up the house when she has step-bro ready to do anything she asks of him... OR ELSE! *CFNM Spanking POV and Taboo Cuckhold Fantasy
