10 years of midnight visits to my sister

I started visiting my sister from the age of puberty at dawn. It all started in a winter, back then I shared a room with my two brothers, while my sister shared a room with my parents. My room suffered a rain incident so there was a need for repairs. We all had to relocate, my brothers settled in a bunk bed in another room while I was placed in my sister’s room. Back then I was very young, I had already started in porn and masturbation, but I had never considered my sister attractive, she is one year younger than me. the room was large, at one end, my parents’ bed was located and at the other end my sister’s, luckily in the middle was the bathroom and after settling in, my sister’s bed was completely hidden from the view of my parents by the bathroom, while mine was still exposed.
