In a dimly lit room, a confident domme welcomes her bisexual sub, eager to expand their horizons. She introduces them to a variety of toys, each one designed to teach them the pleasure of giving head. She guides the sub's hand, showing them how to grip the base, how to lick and suck the head, how to take it deep. The sub, initially hesitant, soon finds themselves lost in the rhythm, their mouth filled with the fake cock, their body responding to their teacher's touch. The lesson ends with the sub, breathless and eager, ready to graduate to the real thing.
