With her lithe body tied down, the tattooed redhead t-girl squirms in anticipation, her small boobs heaving as her girlfriend teases her with a urethral sound. The dominant partner, her own body aching with desire, expertly guides the rigid metal into her lover's urethra, drawing out a guttural groan. She then turns her attention to the bound t-girl's balls, raining harsh smacks down upon them, relishing in the way her lover's body bucks and writhes in response to her brutal touch.
