The work features F-cup beauty Ayaka visiting a spa and receiving treatment from Moa. To fulfill Ayaka's wish to 'make her nipples more sensitive,' Moa pinches, pulls, and sucks her nipples thoroughly. With the use of suction devices, Ayaka's nipples elongate, their sensitivity increases, leading her to ecstasy. This work, comprising six scenes, focuses mainly on nipples but also hints at further pleasures. Particularly, the scene with the fourth pair, Yuri Maina and Nagano Kaede, stands out, showing Maina's initial confusion from suddenly having her breasts attacked to gradually feeling pleasure, and then trembling from mutual nipple sucking, which is the highlight. The unique angles of nipple-sensitive spa treatments were fresh and erotic. Additionally, the fact that both the giver and receiver of the treatment feel pleasure solely through the breasts, and that only one pair undresses their lower half later in the film, is distinctive. The contrast between the painful redness from suction devices and the heightened sensitivity is also noteworthy. The interaction between the two starting around the 50-minute mark is full of moments to quibble over, but their expressions of pleasure are enjoyable. A must-watch for nipple enthusiasts.
