You love spending time at your Brother's house especially when his Step-daughter Jess is back from University. It's no coincidence that you always time your visits when you know she's back home. Jess is happy to see you but she's not sure what you are doing in her bedroom? You tell her you've found her sex toy and threaten to tell her Step-Dad. She makes you a deal that she knows you'll be unable to refuse. How does the chance to WANK while she fucks herself with her toy sound? Your hard DICK likes the sound of that, doesn't it?
