Damon Dice knows that his stepsister Mackenzie Moss has a slutty side, but he never dreamed that she would turn that lusty attention on him. He overhears her talking to a friend about the Fuck Your Step Brother Challenge and how she's going to complete it. At least he knows it's coming when Mackenzie corners him in the living room and starts teasing him with her juicy little titties and ripe ass!Damon is no fool, so when Mackenzie bends over doggy style he goes ahead and sticks it in. Mackenzie can't believe how big her brother's dick is as she bangs him doggy style. When she hops onto that cock to ride it in her tight twat, her little pussy can barely take every inch of Damon's big dick.On her back, Mackenzie spreads her thighs wide for Damon to keep banging her bare pussy. Slipping her hand between her legs, she rubs her own clit to double down on her pleasure. Then, when she's satisfied, Mackenzie gets on her knees to suck Damon off until he gives her a facial of cum. As she's enjoying the afterglow of a good fuck, Mackenzie gets back on the phone with her friend to report her huge success.
