Nathan Bronson made a big mistake by making out with his stepsister, Rosalyn Sphinx. It may have been fun in the moment, but Rosalyn is now obsessed with Nathan and wanting more than he’s willing to give. He finds a pair of Rosalyn’s panties on his pillow and realizes that they’re damp. He can extrapolate that the moisture is from Rosalyn’s pussy juices as she masturbated herself to climax before placing her thong on his pillow.Later that week, Rosalyn snuck into Nathan’s room and put on one of his t-shirts. Wearing the shirt and nothing else, Rosalyn confronts Nathan to let him know that she knows he’s been hanging out with guys who are known for going after slutty chicks. Rosalyn tells Nathan that she can’t stand the thought of him with another girl. A few days later, she approaches Nathan while he’s in his bed doing homework. She wants to take a nap in his bed, and before he can protest she crawls in next to him. Faking sleep, she accidentally-on-purpose rolls over so that her hand lands on Nathan’s dick.Now that Rosalyn has Nathan where she wants him, he doesn’t get a chance to say now. She strokes his dick to hardness and then pops it out of his pants so she can suck him off. Rosalyn’s deep throat BJ leaves Nathan at a loss for words and confused enough that she has a chance to slip out of her panties and slide down on his dock. Her stiffie ride goes from cowgirl to reverse cowgirl as she convinces Nathan she has the right idea. Then Rosalyn gets on her hands and knees so Nathan can bang her in doggy. On her back, Rosalyn rubs her own clit and pinches her nips as Nathan gives it to her. He pulls out at the last minute, covering Rosalyn’s muff with the cum shot she’s been craving.
