A beautiful woman who had long craved stimulation became obsessed with the pleasure after being trained just once by a certain older man, and began visiting him three times a week. Skillfully tamed, she became so sensitive that merely pulling the chain attached to her collar would cause her panties to soak, even during short walks. A true masochist, she spreads her own pussy open, begging for more, as her depths are thoroughly trained by a thick cock. Drowning in this pleasure, she grows increasingly dependent—completely helpless against her addiction.
