JOI CHALLENGE AND CUM COUNTDOWN

This is a custom video that came with this request: "I would love a custom where you wear a sexy bra which makes them boobs really stand out. The custom is basically a joi challenge, where the challenge is for me to not cum before you give me the permission in the end and while you tease me with your amazing boobs and dirty talk like 'Do you really think you can hold out until the end?' and 'I can see you're already ready to cum.' You can also tell me to stroke faster or slower of course and show me the pace with your hand. Your goal is to make me cum before the end lf the clip, and If I reach the end, you'll give me a short countdown to cum."
