In a grimy, industrial setting, Dr. Lomp, the master of kink, takes on Petra, a naive teen desperate for his brutal teachings. He strips her bare, her body trembling as he inspects her closely. Dr. Lomp's hands, rough and calloused, guide her through a gauntlet of pain and pleasure. He forces her to taste the leather of his whip, to feel the sting of his crop, and to endure his merciless paddling. Petra's tears mix with her sweat, her body marked with welts and bruises, yet she craves more, yearning to please her master in this taboo, extreme bondage session.
