Raul Costa has a hot stepsister Lya Cutie who is always horny as hell. When Raul walks in on Lya masturbating yet again, he tries to tell her to cut it out. Lya tells him to just wait until she has gotten off before he lectures her, but Raul storms away.

Later, Lya corners Raul on the couch and begins to masturbate in front of him yet again. When Raul protests that he's her stepbrother, Lya suggests they should just do some mutual masturbation. When she sees how nice Raul's cock is, though, she can't help but get her hands and mouth involved. Soon enough, Lya is blowing Raul as he strokes his stepsister's ass.

Raul's day gets even brighter when Lya climbs aboard for a cowgirl stiffie ride and then a reverse cowgirl ride. She gets on her side so they can fuck as they spoon, then onto her knees so Raul can dick her down from behind. When Raul has finished pounding Lya on her back and blown his own load on her stomach, his petite stepsis asks if they can do this again sometime.
