This is a work featuring Shishido Riho's first challenge as a seductress sister. While staying home alone, the male protagonist is tempted and becomes aroused by her voluptuous soft breasts, leading to an affair. The film includes enticing scenes like titty-fucking, nursing hand jobs, and nighttime sex, making it impossible to resist her allure, especially with her bra-less, alluring breasts right in front of him. Although there are some opinions regarding the production, there are plenty of subjective shots, and Shishido Riho's cute expressions during the intimate scenes shine through, creating an enjoyable experience overall. Furthermore, her seductive attack-type smile is irresistibly erotic.
