The girls compete to get step bro to decide whose butt is better next. When he still refuses to make a firm decision, Coco gets the bright idea to start rubbing his dick. That turns into the girls working side by side to give him the best handie and then the best blowjob. Things keep on escalating from there, with Percy getting to her feet and hopping onto brother's dick to ride him in reverse cowgirl. Coco helps her friend out by rubbing her clit, but she's not about to be outdone. She peels off her thong and then climbs aboard on Seth's fuck stick, riding him in reverse cowgirl just like Percy did so that he can make a proper advice about going back to school.
