Jason is having tons of issues that he is taking out on his stepsister. When his stepmom, Britney Amber, confronts him about it, Jason responds by giving her some lip and then flashing his dick at her to get her to leave. Britney does go away, but she returns to actually talk to Jason about what's going on. He finally admits that he's hard all the time and isn't interested in going to a doctor. Britney figures that as his stepmom it's important that she takes matters into her own hands.
She takes off her shirt and lets him see her huge boobs as he tries to jerk himself off. That's not working, so Britney keeps undressing until she's down to her thong. Jason takes the opportunity to rub his dick over his stepmom's hairy slit and then push it inside. Britney doesn't want to admit it, but she likes her stepson's dick inside her as she turns over so he can fuck her doggy style while Jason squeezes her big ass.
Britney's next step is to try sucking Jason off, but her BJ doesn't do it for him. She decides to ride his fuck stick while he watches her giant knockers bounce with each stroke. Turning around, she gives him a reverse cowgirl ride as he squeezes that booty. Britney keeps leaning forward farther and farther until Jason winds up on his knees behind her for another doggy style pussy pounding. He finally gets off as he strokes himself off all over Britney's face and into her waiting mouth.
