A while ago, I went on a tropical vacation with my girlfriend and her family. We were sharing a suite, which meant we had no privacy. We could find time to kiss, but with a fear of being interrupted, all this led to was repeated cases of blue balls.
After several days, we were both feeling it. My morning wood was hard as a rock, and there was a very real possibility the friction of my cock against my underwear was going to make me cum in my pants. I almost took matters into my own hand, but masturbation wasn’t going to cut it.
Needing to find _some_ privacy, we decided to go to the beach after dinner. On the surface, we were going for a swim and a romantic moonlit walk. So of course I made sure to grab a few condoms with our towels.
The beach had chaises for people to relax on, and after dark, it was relatively empty. We pulled two lounges together, spread our towels over them, and lay down next to each other.
