I'm only 1 year younger than my brothar and during highschool we started to have sex then when he was 17 he decided to go away from our home town and we almost never see each other. He sometimes calls to check how Mom and I'm doing. How I'm 26, our mother got sick and my brother decide to come back home. We basically started where we left, with the advantage that we both have more experience and know what we like.
