"A few years ago I was vacationing in Greece with one of my friends. We were sunbathing on sun loungers just like this one. Between us and the sea was another row of identical loungers. As soon as we got there a teen boy lounging in front of us started to ogle at us just like the girl in the photo. This was quite flattering of course, but not that unusual by any means.
However a bit later I noticed his hips moving up and down as if he was very slowly humping the sun lounger. That lasted just couple of minutes before he pushed the hips down one last time and collapsed on the lounger eyes closed. He must have cummed into his speedoes! A moment later he dashed into sea, probably to was it up.
That was both discusting and very arousing encounter. Have joked about the speedo boy with my friend a number of times since then..."
