Penelope Kay is trying to become a therapist. She's working on her clinical manner and her stepbrother, Apollo Banks, is helping her out. Penelope really fixates on it when Apollo starts talking about having a girl is important to him. She asks him if there's any problem in his personal sex life, and when he admits that he doesn't have as much stamina as he'd like. Penelope has her stepbrother lay down on the couch as she describes a sexy situation where a hot girl is naked, riding his dick. Penelope finds herself straddling Apollo's hips in real life as her fantasies take over her common sense. As she leans in to plant a kiss on Apollo's lips, Penelope snaps back to reality and tells her stepbrother that she can't do this.Later, after Penelope has been giving him the silent treatment for over a day, Apollo joins his stepsis on the couch and tries to talk to her. That seems to help Penelope out since she decides that she can be a love coach even if she messed up earlier. Getting to her knees, she unzips Apollo's pants to free his stiffie so she can give him the help he deserves. She talks him into letting her blow his big cock. Opening nice and wide, the busty coed goes to work sucking away at her stepbrother's erection. Using both fists and her hot mouth, she really gets Apollo revved up. Penelope invites Apollo to give her the same treatment when she gets to her feet, peels off her clothes, and then lays down on the couch to masturbate. How can Apollo decline such a blatant invitation?Now that Penelope has demonstrated how she intends to help her stepbrother out, she holds nothing back. Pushing Apollo down, Penelope climbs onto his hips and slides on down so she can ride him in cowgirl. The position has the added bonus of shoving Penelope's big naturals right into Apollo's face. Turning around, she continues her ride in reverse cowgirl. Then Penelope gets on her knees to invite her stepbro to fuck her from behind. They wind up with Penelope on her back, encouraging Apollo to finally cum for her. When she's been filled up with a nice creampie, Penelope offers to keep working on whatever stamina problems her stepbrother thinks he has.
