A bi-curious sub, bound and hooded, is led into a room by his mistress, ready for his first bisexual experience. She orders him to service her strap-on, slapping his face with it, before pushing it into his mouth. He struggles, drooling, but she persists, "You're going to be my little cock slut today." She invites her bisexual friend, and together, they humiliate him, making him suck both their cocks, spitting on him, calling him their "slave." They double penetrate him, using him as their toy, pushing him to his limits in this intense bisexual threesome.
