It was around the time when my cousin girls, who came to me with admiration as "onee-chan, onee-chan," were about to become adults. Such girls came to play for the first time in a while and went to the bath together. A strange face comparing the small breasts that are about to swell and my adult breasts. My pubic hair that doesn't grow is strangely nasty, and it tickles my erotic heart, and I'm an erotic and useless adult who unintentionally becomes a lesbian.
