JOI challenge and cum countdown

Joi challenge and cum countdown - "hey! 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... and you tell me tribute if i came before the countdown :) i would like if you made the challenge more difficult throughout the clip;) and i would like closeups to tits and maybe some tits bouncing:)"
