Beach day with [M]y two best [FF]riends ends up in a ENF/CMNF situation after we have to run away from a storm

This story might be a bit long and not the wildest, as it doesn’t involve full nudity. However I like it a lot since I lived it in person, so I’m sharing it with you. Back then I already had quite a strong kink for this kind of scenario and it happened by pure chance so I received it like a gift from the heavens.

It happened 4 years ago. I had decided with my two best friends (I’ll call them Marina and Arianna)that we were going for a beach day. We almost cancelled the plan because the forecast announced a storm in the afternoon, but we believed we had a couple of hours of sun, so we decided to go anyway. We went belgian town which had two beach areas. One of them was next to the center and it was the most touristic part. The other one was sepparated from the center by a small harbour you had to cross in a public boat. It was a less urbanized and quite more empty, there were some buildings in the surroundings but not many people living or hanging there.
