We went to visit relatives out of state where I had my first incestuous experience and my first blowjob. It was at my Mom's eldest Sisters house.

On our first full day there my cousin Mary, my brother and I went up into the woods. We'd been out there awhile and eventually we started talking about sex as young people usually do. So I started bragging about the size of my cock and Mary chided me, "Oh sure! You probably have a little boy dick!".

I countered by saying, "What's it matter? You wouldn't know what to do with a cock if it was right in front of you!"

Her back stiffened and she said, "Oh yeah?! Get it out and I'll show you! I know what to do with a cock!"

I hesitated a little at first but then I remembered what a friend who was a few years older had told me, "Never turn down pussy! I don't care if it's your own Mother! Get that pussy!". So I thought, "Fuck it!" and opened my jeans and pulled my cock out. Mary started pumping it. It felt incredible! I was the only only that had done that until then and I was rock hard instantly!

Mary was watching it grow in her hands, eyes glazed over, "K you're way bigger than Billy! But not bigger than my Dad". Next thing I know she leans in and takes my cock in her mouth and OH MY GOD! It was so warm and wet, and she started sucking and the pressure was pulling more of me in. Then her tongue started swirling around my tip and my head started swimming and my knees got weak. My hands instinctively sought for something and I grabbed her head. Then she took me out of her mouth, "Mmm K, you've got a really nice one!". Then back in her mouth my cock went!

My Brother meanwhile was watching mouth hanging open and bug-eyed. Not really knowing what to do.

Mary went back to work on my cock intent on proving that she knew what to do with it. She was back to sucking it hard and using her tongue as well as bobbing down on it good and deep. I mean I was in her throat over and over until she lost her breath. It was incredible! Again my head was swimming and it wasn't long before I felt my balls start tingling and my cock started twitching. Mary pulled it out so only the head was left, wrapped both hands around it and sucked my cum into her mouth. After she let it stay on her tongue for a few seconds she swallowed it down and said, "Mmm you've got good cum K! I love feeling them squirt in my mouth as they're pumping in my hand!".

So after; we were walking back and she told us that her and her friend Billy had been fucking for some time as well as gave us some specifics. Then she asked if we could keep a secret, and we said, "We're your cousins Mary of course we can keep a secret."

"Okay but you can't tell anyone.... I have sex with my Dad and so does Patty." and she waited.

"Really? Does he make you or -"

"No. We have fun and we love our Dad!"

And her story is hers to tell, I don't know it. All I know is that my cousins Mary and Patty used to have sex with their Dad. My cousin Patty comes into my story a few years later.

The rest of the weekend was spent with family and hanging out with Mary and Billy at his family's horse farm where there were several other sexcapades I could tell you about some time.
