Your femdom mistress, well-versed in the art of bisexual slavery, knows exactly how to make you squirm in delight. She orders you onto your knees, presenting your ass to her. She runs her hands over your body, feeling your muscles tense in anticipation. She reaches into her toy box, pulling out a thick, textured dildo. She pushes it into your ass, fucking you slowly, letting you feel every ridge. She smacks your ass, leaving red handprints as she continues to fuck you with the toy. She commands you to stroke your cock, but not to cum, not until she says so.
