After actually watching this work, I felt it was an ambitious piece that thoroughly explores the theme of fellatio through panties. In particular, wearing the same bikini-style underwear as the male character while viewing enhances immersion and doubles the excitement. Even when erect, deliberately avoiding self-stimulation and instead savoring the stretch of the bikini fabric while playing with one's nipples yields a unique pleasure. Some reviews call it a 'big miss,' but this depends on personal preference; as the title suggests, panty fellatio is the main focus, with other acts included as options. The actress Hibiki-chan delivers a stable performance that solidly elevates the work. However, if purchased with the understanding that it's through panties, it won't disappoint. For fans of panty fellatio, satisfaction is high, and a version with even soggier panties could heighten the excitement further. The overall impression skews toward younger women, with carefully selected actresses who suit bikinis or thongs, as baggy panties or boxer types would diminish the appeal of panty fellatio. While there are requests for a version featuring women in their 30s or older, the current direction feels somewhat lacking. More realistic staging of scenarios inside the panties could create an authenticity comparable to the real thing, improving the work's quality. The friction of the fabric stimulating the mucous membranes is distinctive, and the frustration of not being directly touched paradoxically enhances the pleasure, leading to an inevitable climax inside the panties—a brilliant embodiment of the theme.
