Bonnie "Sisters Payback"

Bonnie came home a few months ago and found her sister sitting with her legs open and her boyfriend wanking over her so she now feels it's only fair that she gets revenge. You haven't been dating her sister for long but you are more than happy to help Bonnie out when you realise what she has planned. She bends over the couch and tells you to take your dick out of you trousers and start wanking over her while she teases you and talks dirty.
