I'm wearing a sexy adult school uniform with heels and pantyhose. I want you to jerk off while I inflate this 17 inch crystal red balloon. Stroke faster as I blow the balloon up bigger. With each blow, your balls fill with cum. When the over-stretched balloon can't hold another blow of air, and your balls are about to overflow with cum, and the balloon pops, I want you to blow your load! Can you guess when it will pop? I can't wait until both you and my balloon burst!
