Your step-Daughter is a cunt to you.. talks to you like garbage and you just let her! You don't know why.. but maybe its the way your cock twitches when she gives you that evil smile.. those angry eyes.. that hurtful laugh.. her wicked words turn you ON..and tonight after she demands a new laptop, pushing you one step too far, you decide to teach her a step-son in manners by pushing your dick into her dirty mouth to finally shut her up.. but even then, the dymanic stays the same.. its her who is still in control.. teasing you for being a rotten pervert and ALLOWING you to use her body.. just as long as she gets money in return of course!
