A petite girl with small breasts was made to drink suspicious herbal medicine at a breast enhancement salon. As she undergoes the treatment, she is calmly tormented and becomes excited, creating a work that can be enjoyed for its high sensitivity and beautiful appearance. While there is a regrettable lack of nipple play, standout elements include scenes where oil is dripped onto the treatment gown to enhance the sensual feeling, and the erotic expression when being penetrated from behind. The contradiction between the lewd lower body and the cute face skillfully portrays an exquisite level of erotica.
