what are the signals (body language)
spreading legs as they look at you and smile is usually a good sign....
Spreading their legs is a good one - you see that one a lot. if it's a guy it's obviously a lot easier to tell if he's interested because he'll bone up while looking your way. But before it gets to that point, one good to know is if the person is "mirroring" your activity. It's something that's been observed by psychologists in many studies. A person who's interested will literally imitate your movements and posture. You flip on your side, then they do. you roll onto your stomach, and then they do. You sit up and look at the water...it can go on and on.
Last summer at the nude beach there was a couple there a few times when I was there. The one day she was laying on her stomach then when I went for a swim she immediately rolled over and spread her legs wide open in front of me while I was swimming and was watching me while rubbing herself . Stupid me didnt even realize it at the time. I hope she comes back alone this summer so we can see what happens.
Saw a bloke at the beach yesterday keep glancing over towards me so i spread my legs and slowly started stroking my cock. About five minutes later he came over and asked me to put some sun cream on his back.
I started with the shoulders and then worked my way down, he had a cute ass so i spread some on there with no objections, my finger then slipped between his ass cheeks and found his tight hole. I fingered up his ass a while then he said i need some spread on the front so i started on his cock and things progressed from there....
