We're going to play a ball slapping, edging, JOI game today. Your favorite! Before we begin, I'm going to have you bind your balls up with a band. This will get them nice and swollen, ready for your slaps. The rules of my game are simple. When I slap my ass, you slap your balls. When I give you permission to do so, you will stroke as I tease you with my body. You will ONLY be allowed to cum when/if I allow it.
