Mistress Tina WILL be obeyed... & she has number of plans for her slave, including stretching his balls with pulley, which surely hurts large-time, whic no doubt explains why she seems so pleased with herself. Also stretching his nipples, which also must cause him great pain. than there's large black dick -- vibrator, of course -- that she feed to him so he can sucking on it... oh, & lets not forget scene where she's riding his face with big size black tool strapped on to it. Mistress certainly knows how to inflict pain on an unworthy slave!
