My cousin and her parents visited my house, where I live alone as a university student. They left their daughter with me, and by chance, I started living together with a teenage girl from an all-girls school. My cousin, whom I hadn't seen in a long time, had grown very cute and her body had matured. During the three days of winter vacation, I spent every waking and sleeping moment with my cousin, creating a dream-like record of my precious memories, where we did it over and over again.
