Circle Momiko's popular nipple-focused original work has been adapted into a live-action version!! A childhood friend suggested that they play a "nipple guessing game", but... every time the nipple is barely brushed against the areola and the tip is rubbed, it makes her clench in her uterus...!! She is teased and teased, and gradually developed until she cums! With brushing, prodding, oil teasing, nipple-tweaking sex, etc., her nipples are teased and teased the whole time, and she goes crazy!! Sex feels good, but it's not enough, and before she knows it, she's begging for her nipples to be teased... Once you develop your nipples, they feel better than the clitoris!!
