Around 4 years ago I was sent on a work trip. I have them quite often. This time I was working on a Spanish island. I was given a few days off and decided to go and do some bathing in the dunes not far from my hotel.
I was wearing a purple micro sheer string bikini, but I usually go topless or nude at the beach. I basically just wear the bikini to go through the hotels before I get to the sand.
I found a nice place, quite out in the open and stripped off everything, so I could enjoy lying on the sand naked.
As usual, the heat and the fact that I was naked in public got me a little horny and I started to rub my nipples. I then had one hand on my pussy and I started to stroke my clit. I guess I must have been going for no more than 2 minutes when the guy arrived and shouted at me.
'Hey, that's not allowed here'. He said something else too, but I didn't catch it all.
He must have just arrived, but when he spoke he was standing right over me.
I don't remember exactly what he said, but he told me that he would call the local police and have me arrested unless I carry in while he took pictures.
I could have just run, I mean, I doubt he really meant that he would call the cops, he was just trying his luck. I could also just have ignored him, picked up my things and left. He was quite imposing though, and his tone was very authoritative.
