I hadn't thought anything of it until now, but I'm conscious of my younger sister who has grown up recently. A rounded body, a slightly swollen chest, a plump buttocks, and plump thighs. Even just being in contact with my sister as usual, I can't get my eyes off my sister's body. I can't stay even if I'm standing or standing, and when I sneak into my sister's room and see her sleeping, I can't suppress my desire.
