In lesbian works, there are many featuring Kitagawa Erica and Yokoyama Mirei. It's well-known that they are close friends in private, but they have only seen each other naked once during a co-starring role. This film marks their first meeting in a lesbian context and their first overnight trip together. Kitagawa, whose erect nipples are spotted, blushes in embarrassment, while Yokoyama, hiding her face, receives cunnilingus and experiences a massive squirting. The two, showing reactions clearly different from a typical AV shoot, begin to confess their feelings amidst a mix of tension and shame.
