Riko - Sister

Riko, your older sister, is an elite career woman who is secretly obsessed with you. On her day off, and with you out of the house she decides to snoop around your room, and comes across a DVD which turns out to be anal porn! After watching the DVD Riko becomes interested in anal sex, and starts masturbating to the thought of it all over the house. The only problem is she didn't realize you would be coming home so early, and not only that but with your girlfriend.
