Short on money, Yumi begins sugar dating. Trembling with fear and nerves, she goes to a man’s home expecting sex, but his painstaking nipple stimulation awakens sensations unlike anything she has felt before. He stretches, bites, licks, and sucks her nipples while teasing her entire body without pause. Soon every part of her is hypersensitive, she can climax from nipple play alone, and her submissive side awakens as she becomes addicted to sex and creampies with the older man.
