Mistresses Mei and Sierra spend the evening playing with their slaves. Mei with her medical salve, Jim and respirator wearing latex clad Sierra with her gas mask gimp slave she has on a leash. The dominatrices humiliate their slaves with switches, stepping on them, cutting off breathing and verbally humiliating them. Repeatedly, Sierra's slave attempts touch her and Mei for which he's punished each and every time with whipping, cutting off air flow to his gas mask, etc. Eventually, he takes Jim's place retrained to the wrack where he's not allowed to watch or pleasure himself to Sierra and Mei lessing out with each other. The video's climax depicts Mei's face against Sierra's crotch beneath her latex dress performing oral while Jim performs oral sex on Mei through his medical mask.
