Tsukasa, a stay-at-home wife, recently moved into the same apartment complex as Ayaka. Although Ayaka works part-time and primarily does remote work, she takes an interest in Tsukasa and brings over health products from her job, asking her to try them out as a tester. Gradually, she relaxes both Tsukasa's mind and body, leading her into a world of pleasure. Ayaka is bisexual and finds Tsukasa particularly appealing.
