A hooded slave, bound and helpless, is the centerpiece of a dark, dungeon-like room. Their body, stretched taut by ropes, glistens with sweat as they struggle against their restraints. A stern mistress, her face hidden by a leather mask, circles the slave like a predator. She holds a thick, veined dildo, its tip glistening with lube. Approaching the slave, she forces their mouth open, pushing the toy past their lips, filling their throat. The slave gags, tears streaming down their face, but the mistress shows no mercy. She holds the slave's head in place, forcing them to take the toy deep, using their mouth as a fuckhole, their body writhing in a futile attempt to escape the rough, degrading treatment.
