In a dimly lit dungeon, a slave, bound and gagged, wears a metal chastity device, his cock straining against the cold steel. His Mistress, clad in black latex, orders him to pleasure her with his mouth, denying him any contact with his own aching member. She torments him, bringing him close to orgasm only to pull back, leaving him panting and desperate. Finally, she relents, freeing his throbbing cock, but not before making him beg for his release, humiliating him further.
