Kneeling, wrists bound, a submissive serf awaits her mistress's pleasure. The dominant woman, clad in latex, forces a tight mask gag into the serf's mouth, muffling her moans. She then inserts a hard, vibrating toy into her serf's wet cunt, making her squirm. The mistress commands her to service her throbbing cock, pushing it deep into her throat, fucking her face roughly.
