Bonnie has noticed that you are getting a good look at her tits, you tell her it's her own fault for wearing such a revealing top with no bra and she points out that your shorts are pretty tight. Bonnie can clearly see that you have an erection and seen as it's still early in the gym there is nobody around, she decides to have some fun with you! Bonnie tells you to take your already hard cock out of your trousers and start wanking while she teases you with her perky tits and pink nipples.
