The aunt who came to stay at my house loved me so much that I had sex with her from morning till night, the best two days full of eroticism.

For a friend's wedding, Ruka is asked to stay at the house of her nephew Taiki, who lives alone in Tokyo. Ruka didn't really care that much, but Taiki couldn't hold back his excitement from spending time with his beautiful aunt. Ruka accepts Taiki's sexual desire over and over again with pleasure within a limited time.
