Two lesbian mistresses, armed with a massive strapon, invite a pair of young, eager slaves into their dungeon. The submissive teens, bound and gagged, are forced to beg for their mistresses' pleasure. The dominant lesbians take turns teasing their slaves, slapping their faces, and shoving the strapon deep into their throats, making them gag and choke. The teens' humiliation fuels their mistresses' arousal, leading to a intense, orgasmic threesome.
