In a dimly lit dungeon, a nervous, bisexual sub awaits their Femdom mistress. She enters, commanding them to strip and kneel. The sub, eager to please, complies, their heart pounding with excitement and fear. The mistress produces a strap-on, its size and realism making the sub gulp. "Prove your loyalty," she demands, pushing the sub's head towards a nearby, well-endowed cock. The sub takes it in their mouth, sucking and gagging as the mistress watches, pleased. She then commands the sub to switch, now sucking a different cock, humiliating them further by making them taste their own cum.
