Rose R "Best Friend's Sister"

You've gone round to see your best mate but he's not home at the moment. Rose, his sister, says he won't be back for a while. She's just about to go for a bath and is only wrapped in a towel. You can't help but get a hard-on at the thought of being with his naked sister! Rose nearly drops her towel with her tits almost peeking out and she notices you perving. You're in luck as Rose wants you to WANK your COCK over her. Don't worry, she won't tell her brother!
