[The long-awaited live-action AI adaptation!Keep the atmosphere the same!]This is a story from when I went back to my parents' house last year during my summer vacation at university.Our family consists of four: my mother, me, my younger sister, and my father-in-law, who was born after remarried a few years ago.When I returned home for the first time in a while, the thing that surprised me the most was how my younger sister was how well she developed.I was growing taller, my breasts were getting bigger, and I was growing more feminine than I imagined, which made me quite a bit scared.I'm a virgin who has no experience with just a bath towel after a bath, so I'm just too defenseless, so I'm a virgin who's not yet experienced, and his butt was in a really good shape... So... Is this the main topic?I was bored at my parents' house, so I decided to do the seminar assignments, so I borrowed a laptop that I didn't seem to use in my father-in-law's room.Looking back at it now I guess it was hiding it.That's why I found it by chance.
