This live-action adaptation brings Circle Momiko's popular nipple-focused work to the screen. An adult childhood friend proposes a nipple guessing game, but every teasing graze around her areolas and scratch across the tips sends pleasure deep through her body. Brushes, rods, oil, kneading, and nipple stimulation during sex keep her constantly teased until she loses control and cums. Sex feels good, but soon it is no longer enough, and she finds herself begging to have her nipples played with again. Once fully developed, they feel even better to her than clitoral stimulation.
