In a private dungeon, a dominant woman teaches her interracial students the art of sucking cock using a strapon dildo. She commands them to kneel, their eyes locked onto the veined, black silicone shaft. She demonstrates, pushing it deep into their throats, making them gag and choke. The students, a bi-curious couple, take turns, one fucking the other's mouth while the dominant woman watches, critiquing their technique. The room fills with the sounds of gagging, slurping, and wet, smacking kisses.
