This work, themed around a hot spring trip, is irresistible for its underlying sense of immorality amidst a seemingly harmonious atmosphere. Particularly, Fumika-chan's divine body is overwhelming, and the erotic scenes in the steam are guaranteed to excite. The sight of her pink nipples and moderately elastic breasts swaying is bound to stimulate the viewer's desires. The imbalance between her plain facial features and her body adds to her charm, and her motherly atmosphere combined with whispering temptations feels so real that it's impossible to resist. Although the older feel of the sister role is a bit concerning, the thrill of reverse NTR and Fumika-chan's eros make this work shine. Great expectations for her future performances.
