I went to a beach in FL awhile back. It was around 7-8 PM when I decided to go into the water, slowly untie my bikini and let them float away so I've no clothes access except for my sandals. Afterward, I went up onto the ground, lay down, spread my legs and play with my pussy like this after I make sure no one was around.
I think I orgasms like 2-3 times right there.
The "best" part is when I have to return to my hotel room completely nude past a bunch of people. The look on their faces was priceless. :3
