Ass Worship JOI Game

I want you to jerk off for me, but theres just one simple rule you have to follow: you can only stroke it when my ass is on the screen! When its not, you have to take your hands off. Youre going to worship my ass and Im going to make you pump it and stop over and over, making you so desperate and horny!! Then at the end, when youre aching to cum, Im going to make you do one more little challenge. You have to edge every time I smack my ass! You have to edge, but you cant stop stroking and you absolutely canNOT cum until I say so!! Finally when Im done tormenting you, Ill let you cum hard for my ass!
