Ricky Spanish is studying the sexuality of men for his homework. His stepsister Cielo West approaches him from behind and reads what he is writing as he is about to finish penning notes regarding a man's ability to hold back on cumming. Cielo argues that Ricky is mistaken and that men lack mental self-control.
Eventually, she demands that Ricky provide evidence. Cielo can't even fall infatuated with Ricky since he attempts to tell him that she's his stepsister. That only presents Cielo with an even greater task. Cielo teases Ricky by exposing her thong by pulling up her miniskirt. Subsequently, she spins around and removes her bra from her shirt.
After a while, Ricky becomes as attractive as Cielo had imagined. Ricky should give it to her and prove he's correct, but Cielo gets on her back and rubs her pussy in response to his double talk about his ability to control his climax.
Since Ricky is merely human, he is willing to give in to his stepsis with that much prodding. Cielo tries to make Ricky cum by using every method in the book. In a passionate BJ, she swallows his balls and cock.
She then mounts him and rides him like a cowgirl, massaging her clit to allow her climax to fully exploit Ricky's shaft. Cielo rocks back to meet every stroke as Ricky, feeling very secure now, puts her up on her hands and knees and gives her a doggy fuck.
For a while, Ricky is able to hold out, but ultimately he comes too near and realises he has to pop. At that point, Cielo sways back and holds him inside of her, giving him the creampie she had been after since the beginning of their fight.
Although Ricky is upset that Cielo made him crack a nut inside of her, Cielo is overjoyed.
