The Mistresses are sounding the slave’s cock and applying a vibrating doxie to his balls. “You have to beg to cum slave - otherwise you just won’t get permission”. “How are things going in his back door? He’s well plugged up”. Lady Bellatrix presses her vibrator to the anal dildo and the slave starts to gasp as he struggles not to cum. Mistress Ava spits on the sound and uses this as extra lubricant. The slave gasps loudly as it slides in balls deep. “Oh God may I please cum Mistress?” The Mistresses give permission and the slave jerks into a massive orgasm.
