In a dimly lit room, a nervous man is bound and blindfolded, his ears filled with the clacking of high heels approaching. His mistress, a dominant bisexual woman, runs a leather-gloved hand over his body, whispering filthy commands. She straps on a massive, veined dildo and orders him to service her, gagging on her strap-on as she face-fucks him. She then outfits him with a smaller strap-on, making him her 'bitch' and mounting him, riding him hard while humiliating him with degrading words, pushing him to new depths of bisexual submission.
