Let's continue...
Just something off topic:
A few months after our first sauna meeting with our friends, we four went to a holiday in italy on a camping site. They slept in their caravan and we slept in a tent next to the caravan. Originally, they proposed that all four could sleep in that caravan. But we rejected as we wanted to have a lot of sex... At first, they did not get that, we had to say it straight that we wanted to fuck

The first night, we had to sleep in the caravan because we arrived late. I am pretty sure, that my friend was jerking himself off an hour after we went to bed. I was still awake and could see what was going on

At the end of that vacation (6 nights), we had fucked 11 times (one time in the communal shower and one time in their caravan-bed when they left for a shopping trip) and they fucked just once... as our tent was close to their sleeping place, they must have heard us at night... I hope, they liked it :-)
In the pool, the other couple made a swimming race. While doing that, the other girl lost her bikini top and pants halfway through the pool. But she just noticed at the end of the race. I enjoyed the sight of her big boobs ...and so did some people that passed by the pool

she was really embarassed ...
Unfortunately, my gf rejected to do topless at the beach with our friends (normally, she does). One time, when our friends left earlier from the beach, she decided to take off her top. Some minutes later our friends came back as they forgot the key of the caravan...so he enjoyed the sight of my gfs tits :-)
Ok, coming back to some other sauna events.
We went to a big german thermalbad with a huge nudist pool.
It was a hot summer day. Surprisingly, our shy friend was staying nude all day. Normally she covers herself in towels after sauna or swimming. Amazing for me. The highlight was, when she sat on a sunchair opposing me and had her bag with her food beneath the chair. She bent down to get some food out of it. While doing this, she put one leg on the left side of the bag, and the other one on the right side. Meaning she simply spread her legs to reach for the food. This opened her perfectly shaven pussy for me. For a few moments I had a perfect view on her opened labia. I even saw her nice clit and the hole, he sometimes is allowed to put his penis inside. So lucky for me

On that day, our sunchairs were next to the pool, so the people in the pool had a perfect view on their pussys. And some elderly men (60+) were relaxing at the edge of the pool facing us...so they were clearly enjoying their naked bodys....
On the same day, we were relaxing in the pool as a couple of about 40 years entered. They were staying next to the entrance of the pool at the edge where they had some massage bubblers (or however these things are called in english). A few moments later, really just some seconds, we could clearly observe, how the women started stroking his cock under water. We were just some feet away and we could see her arm and shoulder move up and down quickly. I am pretty sure, he was cumming in the pool making a relaxed face a few moments later. Afterwards, he started rubbing her pussy, as she was making an excited face...and she clearly had an orgasm as we saw by her face. We were quite amused but the girls were a bit disgusted thinking of his cum swimming around... After the yfinished, they left the pool directly. Seems like nobody else noticed...I think, they would have had some serious problems with the staff if they noticed...
But I was horny as hell after these two events.
A few minutes later at the same swimming session, our friends had a little dispute over something. We stayed next to them as they heavily discussed some issue. While discussing, I seized the chance to open the legs of my gf under water and put my errect penis inside ehr pussy. We were fucking discretely for at least 3 or 4 minutes. When they finished discussing, we stopped fucking. if they noticed, they would have mad jokes of us, but they did not... But still beeing horny, we later went to the locker to get a bottle of water which we had in there. But actually, we used a locker room tohave some fun. She blew my cock heavily. Then she turned around and bent over and i fucked her doggystyle. As we did not have anything to clean up my cum, we decided to cum in her mouth and she swallowed everything. When we left the locker, we saw another young couple entering one locker. They just had a little towell with them..I am pretty sure what they were planning to do in there :-)
