This is pretty tame but I found it very erotic. A couple of years ago went camping with my wife's older sister and her husband. Spent most of the time boating and swimming not to mention drinking.
Me and the brother in law brought up skinny dipping but the wives wanted no part of it. The brother in law is obsessed with my wife's tits and is always kidding her to flash him.
Our last night there it was very hot, most campers had left and we didn't even bother with a campfire. It was getting late but we were all sweating when the brother in law suggested we go take a shower. The wives were all on board until he said we should sneak into the men's shower together.
It took a lot of teasing and bribery to convince them not to mention Tequila shots. What they did not realize is that the men's shower offers no privacy.
I went in first to make sure it was clear but when the ladies entered they freaked out. They wanted to back out, tried to bargain to keep their panties and tops on. Finally it came down to where the guys had to strip first, a lot of nervous giggling ensued.
My wife turned pale and I thought she was going to throw up when she realized there was no turning back. I actually got a bit dizzy as I watched her slowly remove her shirt and shorts, her sister matching her pace. They both turned their backs to us as they removed their bikini tops and panties.
I thought I was going to explode right then and gaging by his erection I think he was too.
As we showered the wives carried on like we weren't even there so it was a quick opportunity for him and I to get our eyes full.
As a follow up we have convinced them to repeat it one more time, but no swaps yet.
