In a dimly lit dungeon, a naked slave is bound, knees wide, ass exposed. A massive strapon, glistening with lube, is presented to her. She opens her mouth, eager to please, and the dildo slides in, stretching her jaws. The dominant force behind the toy controls the pace, pushing deeper until she gags, then pulling back to let her catch a breath before starting again. This is her world, her purpose, and she's loving every second of it.
