At The Beach With My Sister

When my sister turned 16(I was 12), she was allowed to take me to the beach. Not waiting for our parents meant daily and all day beach time. Eventually we found a semi-secluded spot in the rocks at the base of the cliffs. She started going topless when I was 13. By the end of that summer we would both sunbathe nude. By the time next summer was in full swing, we each started masturbating while we tanned our naked bodies.

I was 15 and woke to an odd sound. I looked up to see a guy that looked to be our dad's age standing behind my standing sister as he fucked her ass.

I watched for about 10 minutes before he came in her. She was 19. She lay on her belly next to me on our blanket. I asked her who that was. She just shrugged and said 'dunno'.

That happened a couple times a week to a couple times a day.

One particular time, we were on our stomachs when 2 guys walked up. I guess her reputation had spread. One knelt down and slid into her ass. The other knelt down over me and started rubbing his cock up and down my crack.

My sister and I locked eyes while her ass was getting fucked and as my anal cherry was getting popped.

The visits became a weekend only thing by the time we both got full time jobs. Our tanning area was annoyingly busy on weekends, so fucking seldom happened. It was usually my sister and I with her boyfriend and my girlfriend. We would all nude sunbathe and often suck & fuck.

My sister and girlfriend would each occasionally suck a cock from a stranger while we fucked them, or visa-versa.

It's great conversation we bring up in mixed company now that I'm 55 and she's nearly 60. We love freaking some people out.
