After viewing this work, I was deeply impressed by the role of an employee at a lingerie design company played by Haruka Migawa. She tackles bold lingerie development without any male experience, but her struggles are portrayed realistically. In the scene where she wears large-butt panties while drunk, a male employee's erection leads to a shocking development of intense insertion with a large penis. However, from that day on, the project starts progressing smoothly, and her realization that "I must do more obscene things to understand the charm of lingerie" drives her to indulge in sex, which is breathtaking. The fleshiness that clings to the lingerie is not at all fat, but rather a well-proportioned dynamic sense with a good figure and large buttocks that enhances the lingerie's appeal, seeming to offer a great embrace and making one want to devour it. She embodies the ideal skin woman for men, and the process of even her lewd body being co-developed is, in sports newspaper style, truly a "drama of reversal." Overall, Haruka's growth and physical charm are fused, resulting in a compelling work worth watching.
