Mistress Alex, a stunning dominatrix, humiliates her chubby slave, making him wear a male chastity device and denying him any sexual pleasure. She teases him relentlessly, pushing his boundaries with cruel words and tender touches. 'You'll be nothing but a fat loser, eating my cum for the rest of your life,' she taunts, making him lick her shoes and beg for mercy. She finally allows him to pleasure her, but only with his mouth, leaving him frustrated and desperate for release.
