Ayaka Tomoda's first lesbian work was with Azusa Kiriwara. Over the course of a year, she learned the pleasures of women from Azusa, and with that experience in her heart, she strongly desired, "I want to do it again with Azusan." Azusa also felt the urge to respond to those feelings. Azusa's sensitive spot is her nipples, while Ayaka's specialty lies in her feet. They stimulate each other's weak points, deepening their connection. Then Azusa whispers the word "number one." Ayaka's emotions explode in a moving, climactic finale.
