The first of 6 encounters started when Robert took me for a ride on our push bikes to a bush near our house, we were alone and i was asked to show him... my penis, being 10 years old i kinda knew i shouldn't be doing this and felt weird but we ended up showing each other and ended that encounter with just that.Our second encounter was when i was maybe 14 years old, Robert had his license and would take myself, my mother and brother as well as Roberts girlfriend at the time for drives at night to. The farm also had a nice pond with a dock and a couple of paddle boats. Several of the other kids brought their own assorted watercraft to add to the flotilla. For the purpose of attendance, everyone was considered an adult and had to sign a release. An ambulance was parked at the main home just in case of emergency, but there was no other supervision.It may sound like an odd situation for today's culture, but this had been done for several generations. The one other caveat was that everyone. The dark circles around her nipples were the size of quarters. Her nipples were like ebony pencil erasers."Yes, baby, this is incest. Sex between a child and parent. But it's okay. This is just a girl and her father being naked with each other and masturbating together. Happens all the time, I'm sure. And even if it is wrong, it's what we want to do, right?"She nodded enthusiastically."Did you enjoy seeing my cock spurt cum all over your tits? I must have spewed a pint of hot semen all. "Oh, hi there," Jason said. He made no effort to conceal the huge hard dick swinging between his legs as he finished drying himself. "No classes," I asked. "Nope, canceled today," Jason said as he wrapped the towel he was holding around his muscular torso. "I gotta get home anyway," Susan said as she playfully smacked Jason's ass and undid his towel so that it dropped to the floor to reveal his still hard dick. "That bitch is a freak," Jason said as he reached down to pick the towel up and wrap.
