A big, juicy ass like this in a tiny little thong always makes you rock hard, doesn't it? Don't try to fight it -- just get your cock out and start stroking for me. Pump it exactly the way I tell you to while I tease you with my perfect ass. When I'm done, I want you to show me how much you worship my ass by cumming hard for me. I give you a countdown and then command you to shoot a big load for my ass.
