In this clip Mistress Ava Black and Her friend have thought of a fun and unique JOI game. The game is tough, long and unbeatable – jerking to the beat as guided by the Mistresses. It takes every bit of self control to hold back for as long as possible, trying not to leak, but inevitably its going to happen and likely before the clip has ended. This is where the clip gets really challenging because there’s no stopping when you want to prove yourself to these beautiful Mistresses. The only way to do that is by completing this super extreme jerk-off game. At 20 minutes long this clip is certainly a challenging one!
