Brother wife, sister husband, sister husband sister wife story

In my early childhood my family and my aunt family used to live in the same apartment. That’s where I got my first sexual experience. I seen my sister who was 3 years older than me having sex with my aunt’s son. I saw my aunt having sex too with my uncle. I was fascinated by it and I couldn’t stop watching. I memorized every detail. When I grew older I started to understand the feelings when you look at a girl. I got jealous of my cousin and I hated him for doing this with my sister. When I was 16 for the first time I had sex with a girl in school. When I was 17 I moved away from my aunt family as my family decided to buy a house in another part of the city. But it was too big for us and my cousin and his parents moved in our house too in the summer. We had 4 bedrooms in the house and my family got one of the bigger ones and my aunt and uncle got a small room. My cousin got a small room as well together with me. That’s where our story begins.
