Edging Challenge

If I edge you.. Do you promise not to cum until I say so? If you survive my handjob, only edging and NOT cumming.. I'll take things to the next level and make it even harder for you.. If you manage to not cum in my mouth when I give you a blowjob.. If you just throb in my mouth and hold back all your cum, I'll make it EVEN harder for you. I'll fuck you! I'll fuck you ONLY if you don't cum inside me until I say so.. It's going to be so hard not to blow your load inside my wet pussy, but after I've edged you long enough and decide it's time.. I'll countdown to when you're allowed to cum inside me.. Are you ready..? Hold it in until I reach ZERO! Cum in me now!
