Are you watching me while I do my yoga?! You are such a pervert!!! What is it with guys thinking that I won't notice them watching me when I'm trying to work out? Whatever, I guess you can watch... Are you getting hard right now!? You know I'm your step-sister, right? This is so gross, what do I have to do to get you to leave me alone? Fine, you can jerk off to me, but you can't tell anybody about this! There is no way I'm going to get naked for you!! Ugh fine, I'll take my clothes off just for a minute.
