I live by the sea, and often like to spend many hours wandering up and down the beach. I had always heard that there was a nudist area at the far end of one particular beach I go to, but never investigated since it is about four miles long.
This one day in the middle of the summer it was really hot, and I went walking further than usual, miles up the long stretch of beach, dragging my feet in the surf to try and cool down. A big wave came along and splashed me right up to my crotch with freezing water, which made my pussy start to tingle. I started to feel a bit horny, and had a look around the beach to see if there was anybody around. It looked pretty quiet, so I thought I might find a place to sit and rub my clitty for a while.
As I walked up the beach away from the sea, I spotted a crop of rocks, with what looked like a reasonably private area behind them. I ducked in there, pulled my knees up, and moved my shorts to one side. My pussy was hot and wet, and as my finger slid over my throbbing clitty, I knew it wouldn't be long until I came. As I got really into it, I started to moan a bit, thoroughly enjoying the sensation of masturbating outside in the fresh air, and feeling a bit naughty.
I was on my back with my eyes closed, when I felt a bit of sand hit my face. I opened my eyes, and saw a woman sat on the rocks watching me. I have never been so embarrassed in my life, but the thought of being watched as I stroked myself was turning me on even more! I looked her boldly in the eye, my cheeks flaming, and continued to tickle my clitty. She sat and watched for a while, and I started to put on a bit of a show for her, spreading my legs wide and moaning and groaning.
She jumped down beside me and came and stood over me. She then asked if I minded if she helped me out. I told her to go ahead. I had never had an experience with a woman before, but had often masturbated thinking about them, so this was like my naughty little fantasy coming true. The only difference was that she was very unattractive. At the time it didn't matter to me, I just wanted her to join in. She whipped her shorts off and sat down behind the rocks with me.
She then removed my hand from my pussy, and replaced it with her own. For some reason her fingers were really cold, and feeling them slide over my clitty and in and out of my hole was absolutely amazing. Just then I felt the build up, and thought I was going to explode, she rubbed my little bud harder, she certainly knew what to do. My orgasm tore through me, and I found myself grinding her fingers into my crotch like crazy as I came over and over again.
When I had finished, I wanted to return the favour, but she didn't want me to. I had to just lie there, holding my labia wide apart for her to look up me while she crouched over me and fingered herself. She was very quick, and as she came her face went bright purple, and she grunted loudly over and over. She then ran a finger through her slit, collecting her own juices. She sucked them off, then replaced her shorts, staring at me. Then she said goodbye and left. I have seen her since, walking around the town where I live, but she shows no sign of recognising me. I don't know what I would ever say to her, but I have spent many happy hours pounding away on my pussy and thinking about the orgasm she gave me that day on the beach.
