Cumming at the beach [F] Mast

Today I went to the beach alone to just read and get some sun. I ended up randomly getting super horny, and the thought of masturbating secretly popped in my mind— I was instantly wet. I was wearing a black bikini with shorts over, so I took the shorts off and made a little “mound” with the sand under my towel to create a little hump that I could very subtly rub my pussy against. I opened Reddit, put in some headphones, and laid down on my stomach with my clit up against the mound. I pretended to shift and move around to get comfortable, but I was really just rubbing my now-soaked pussy up against the sand. It was so hot. Whenever a guy walked by me I’d make eye contact and smile just to turn myself on even more. I finally came all over my bikini bottoms when an older guy, about 50, came over to start asking random questions and talking about the weather. He had no idea what I was doing, and when I came I kinda just sat up and moaned a bit, pretending that my muscles were stiff from sitting up and stretching. Definitely doing that again!!
