Our regular fitness instructor called out so I decided to lead the class today. While warming up I catch you staring down my sports bra. I suggest that our workout be clothing optional and strip out of my sports bra and leggings. While we workout I notice your hard-on through your gym shorts, and then comment on the wet spot caused by your pre-cum. I tell you to go ahead and take your clothes off, it is clothing optional, and then encourage you to beat your meat for me. I get so horny watching you bop your bologna and find some things to masturbate with. When I've had all I can stand I fuck you and tell you to give me a cream pie. After you blow your load in my cunt I tell you to come take a shower with me and I give you a golden shower.
