Eyes locked on the submissive's glinting retainer, the domme slides her strap-on in and out of his mouth, relishing his gagging noises. 'You like that, don't you, you little retainer slut?' she teases, pushing him onto the floor. She straddles him, grinding her dildo against his crotch, forcing him to stroke his cock. 'Cum for me, bitch,' she growls, pinching his nipples. As he explodes, she shoves her fingers into his mouth, smearing his cum, 'Lick it up, you nasty little cum-eater.'
