The nudist camp where I go once in a while has a small pool indoors that is very intimate. The owner built it to be like a tidal pool with lots of private little coves and secluded beach-like areas. It also has lots of air jets which are generally on so you can't see under the water and you have to be close to each other to carry on a conversation.
The last time we visited the wife and I spent quite a bit of time in there because it was a little chilly outside. It was our habit to spend a lot of time coupled, my wife either spooned into me or facing with her legs around my waist, my cock inserted firmly in her pussy in either case. Most people knew what was going on but as long as you didn't have sex right on the pool deck nobody cared, and it was common to have sex in this pool.
We had been in the pool for a couple of hours when my wife called my attention to a young lady a few yards away from us. She said that she had been watching us for some time and she thought that she would go find a lounger under the sun lamps and I could see what happens.
Sure enough, just as my wife was disappearing around the corner to the sun deck the gal started slowly breast stroking in my direction. When she got to me she stood close and asked if she could feel me. I said sure, if I can reciprocate! Without any hesitation she reached down and found my cock, which was still pretty hard from being in my wife's hot pussy. At the same time I found her furry pussy and slipped two fingers into her with no trouble. She had obviously been playing with herself while watching us fooling around.
"Oh my god!", she gasped, "Will you fuck me with that?"
"My pleasure," I replied, and we quickly got coupled together, her facing me with her legs around my waist. She did all the work, thrusting onto my cock and squeezing tight with her pussy when she pulled back. I held her close and tight so she wouldn't be quite as noticeable!
She was obviously pretty aroused from playing with herself and she had three orgasms within a few minutes.
"Cum in my pussy, Oh please cum in me ..." she moaned in my ear. I looked across the pool and saw my wife watching us with a big grin on her face. When she noticed me looking at her she gave me the thumbs up! I grabbed my partner by the ass cheeks and pulled her close and pounded her hard about three times and filled her pussy with my hot cum.
We have since become quite good friends with her. She is bi like we are so everything works out just fine.
