When I was approximately 12 I started puberty and being the oldest of 6 (5 boys 1 girl) I wanted to show off. First all my younger brothers saw me naked, they couldn't stop staring, especially at night, because I would look at porn mags with friends.

Eventually, I jacked off in front of them all. Only the one brother didn't seem to care as much. By the time I was 17 I had had sex with my sister & 4 of my brothers.

This continues on to this day with 2 brothers and sister to a lesser extent, because she lives in a different state. I am married with 3 son's.
