Chris looked slightly less enthusiastic and I knew he was worried about getting aroused in this kind of setting. It was on my mind as well as it would be different to our previous experiences at the waterpark and on the river. I doubted we could walk around with erections.
Before I had a chance to speak, Chris placed the question that was at the top of both our minds. "Um, what if we get excited?"
Jackie and Sylvie both rolled their eyes. Sylvie answered "All you guys ever think about is having an erection! It's just like at the sauna, you should try to control things but if it happens it happens. Things outside at the pool and especially in the lake are a bit more relaxed. I can remember my brother getting excited when he watched a group of pretty German girls playing volleyball. He couldn't keep his penis down despite my mother and father sending him into the water numerous times to cool down. I remember teasing him endlessly when he came out after ten minutes with no change!"
We all laughed and Chris said "I still can't imagine being naked with my family, especially if something like that happens!"
Sylvie described the facilities we were all keen to get going. Since Jackie and Chris were leaving the in evening the next day, the plan was to return home tonight so they'd have the morning to recover and prepare for the trip back home.
The conversation then switched to the events of the previous night and Chris asked what he'd missed. I was relieved when Jackie took the lead and told him everything that happened. It was exciting to hear her describe the events from her perspective and I couldn't help but get hard again. Chris didn't seem upset and when we stood to clear the table it was obvious that he'd become equally aroused at hearing the story. When Sylvie noticed our erections she said "We can't leave them like that, Jackie!"
Chris and I froze and looked at each other. What was Sylvie suggesting? My question was answered soon enough as Jackie and Sylvie whispered to each other and then took each of our cocks into their hands and went onto their knees before us. I could barely contain my excitement. Sylvie and I had our eyes on our friends and the same was true for them. I felt my balls tighten in expectation and I knew it wouldn't take much for me to come.
Jackie began to stroke Chris's cock and I felt Sylvie do the same to me. Chris and I both moaned in pleasure. It was one of the most erotic moments I'd ever experienced. Chris must have felt the same as I heard him say "Oh god, I can't hold it!"
Sylvie's hand froze on my cock as we both focused on our friends. Jackie sped up her motions and within seconds Chris gasped and his cock began to spurt. Sylvie's tightened her grip on my cock and I only just held back my own orgasm. After the first spurt, which hit Jackie on the nose she opened her mouth and placed the tip of Chris's cock into her open mouth. His second and third spurt oozed onto her tongue before she closed her mouth and sucked. All the tension left Chris's body and he almost sagged to the ground.
I felt Sylvie's hand start to move and gasped as she rapidly stroked my sensitive organ. Chris and Jackie were watching intently as I approached my peak. "Soon!" I said to warn Sylvie. She smiled and then opened her mouth in preparation. Seeing her do this was all that was needed and I felt my cock swell and then pulse as semen was ejected. I gasped loudly as the first spurt hit her mouth and chin. Number two and three followed rapidly with about the same volume. Two more slightly weaker spurts followed with the last one hitting Sylvie on her chest.
I felt weak and was panting when Jackie said "Oh my god! I've never seen so much cum before."
"Jesus man! When was the last time you unloaded?" asked Chris.
I mumbled "Um, last night when Jackie was here."
The two girls laughed and stood up, leaving two small puddles where they'd been kneeling. Jackie was staring at my cock as it lost its stiffness and began to droop. She licked her lips and seeing her do this almost made me hard again. Chris was equally fascinated with Sylvie. He watched her as she licked around her mouth and then used her fingers to wipe my ejaculate from her chin before licking them clean. I couldn't resist bending forwards helping her by licking her chest and breasts clean.
When we were done the four of us stood looking at each other in wonder. Everyone said "Wow!" at the same time and we all started laughing. Our first sexual act together had gone well and I knew it was just the beginning.
Sylvie was the first to recover and said "Come on, let's get a move on."
We threw on our clothes, packed our gear and were down in the car and on the move within ten minutes.

The drive was uneventful. Sylvie was at the wheel and Jackie next to her. I sat in the back with Chris. When the conversation up front switched to fashion, Chris and I tuned out. I was enjoying the scenery when he said "Bloody hell, that was amazing!"
I knew what he was talking about and said "Yup!"
"I've never experienced anything like that before!" he said and then added "It's so different seeing it for real."
"Well, it was a first for us!"
"Jackie watched you two at it last night so technically it's your second."
"I meant watching someone else and Jackie couldn't see much. But I can tell you it was hot as hell knowing she was watching us."
We sat in silence for a moment and then I decided to tell him what Sylvie and I had discussed. Chris gulped and licked his lips. "When you say join in, do you mean what I think you mean?"
"Well, we were talking about the four of us having sex in the same room and watching each other."
He nodded and I continued, "we decided we'd just let things happen naturally and not make a plan, so basically anything could happen."
I could see he was quite shocked. "Look, there's no pressure, it's just a fantasy. We're not really sure how we'll feel if it happens for real so we agreed that if anyone is uncomfortable we would stop."
He nodded and I said "and of course it all depends on you and Jackie feeling the same way."
He turned and looked out of the window in silence for a while and I didn't push him for an answer. It was quite some time before he said "You know Paul, this trip has already changed my life and my relationship with Jackie has never been better. Speaking for myself, I can tell you that I can't think of anything I'd rather do than take things further with you and Sylvie. Judging by Jackie's reaction to what happened last night and how things went this morning I'm pretty sure she's thinking along the same lines but I'll have to talk to her to make sure."
I nodded and we sat in silence for the rest of the trip.

After crossing the border without being stopped, we arrived at the spa at around 11 o'clock. It was another beautiful day and the temperature was already high. The parking lot was quite full so we were expecting the place to be busy.
We exited the car and stretched before unloading our gear. It was strange to be going to a spa without having any swimwear and all we had were towels. At the entrance we joined a short queue and soon had our wrist straps on and were heading to the changing rooms
I noticed numerous signs saying "FKK zone" and asked Sylvie what it meant. She explained that FKK was the acronym for "Frei Körper Kultur" which meant as much as "Free Body Culture" and was used in Germany to depict nudist areas. The changing rooms' or rather changing area was very different to the one at the waterpark near our home. Here there were no cubicles at all, just rows of lockers with benches between them. We were confronted by numerous men and women of all ages in various stages of undress.
Sylvie entered without hesitation and I followed her with Jackie and Chris bringing up the rear. We moved through the people and I couldn't help but looking. We had to pass three rows of lockers before Sylvie found a bench with space for the four of us. She immediately stripped off her clothes and was naked within a matter of seconds. She was already hanging her clothes in a locker when I followed her example. While I was removing my clothes I took a look around.
I could see a group of young naked guys eying Sylvie. They were openly staring at her spectacular ass and laughing and nudging each other as they looked. I felt my penis lengthen slightly as I imagined what they were saying. Sylvie turned to face me, waiting for my clothes. I quickly finished undressing and handed her my clothing. She smiled at me and after a glance at my crotch said "I can see you're already enjoying yourself!"
She knew me so well! My penis was just a bit elongated but she could tell I was aroused. I smiled and said "Well, you've got a group of admirers watching your every move and you know I love that!"
She smiled and purposely dropped my shorts before bending over slowly to pick them up. The group of guys behind her stopped laughing and silently stared at what she was showing. When she straightened I could see her nipples had grown significantly. I glanced over her shoulder and could see all four of the boys showing a reaction and trying to cover their crotches with their hands. Jackie had noticed what was going on and decided to join in the fun. She slipped her summer dress over her head and was naked in an instant.
The guys watched as she bent over to untie her shoes giving them a similarly spectacular view. Chris was the only one still dressed and he was moving slowly as he took in the sights. He was oblivious to Sylvie's and Jackie's actions as he was too busy trying not to be caught as he looked at the other female flesh around us. Seeing he was particularly interested in someone behind me, I turned to take a look.
I instantly knew what attracted him as apart from a couple of men and an elderly couple there was a stunning blond women getting undressed. She was down to her underwear and just as I turned she unclipped and removed her bra. She had a spectacular set of breasts but to me they looked somewhat artificial and were capped by rather small nipples. I turned back and said "Come on Chris, get on with it."
Jackie and Sylvie laughed and I said "What's so funny?"
"Take a look at our fan club!"
I glanced at the group and saw they were being berated by a naked old woman. She was talking to them sharply and wagging her finger. The guys were all pink with embarrassment and still had their hands covering their crotches, but I could see all of them had erections. I smiled at Sylvie and Jackie and said "You two are evil!"
Chris was down to just his underpants but was hesitating. We could all see the obvious bulge and I said "You better calm down or that old lady will all over you next!"
He gave me a confused look and I said "There's a group of guys behind you that enjoyed watching our girls getting undressed and now they're paying the price!"
Chris turned just caught the end of the rant. The old lady glared at us and I thought for a moment she was going to come over and give us a similar lecture. I concluded that she may have seen Sylvie and Jackie's part in the drama. Chris quickly turned back and pulled down his boxers. His cock was still slightly swollen but he seemed to have things under control. We quickly put the rest of our stuff in the locker with only our towels followed the signs to the sauna.
Sylvie again led the way, this time with Jackie by her side. Both of them looked spectacular and drew a lot of attention. Once we reached a less crowded area Sylvie asked "So, what do you want to try first?"
"How about we try that Japanese style pool you mentioned and then hit some saunas before swimming." I said.
Everyone agreed and we followed the signs to our chosen destination. As we walked through the large complex I noticed that, in contrast to the saunas we usually frequented, people here were even more relaxed about being nude. Virtually everyone was walking about naked with only a tiny minority covering themselves with their towels. I mentioned this to Sylvie and she explained that at our sauna you're encouraged to wear a towel when not in the saunas but here it was a totally nudist place.
The Japanese pool wasn't very busy and after hanging our towels on the provided hooks we entered the shallow and very warm water. It barely covered our knees and we waded in before settling down in the water. "Phew, this is hot!" said Chris, stating the obvious.
"The water is around 40c" said Sylvie "You shouldn't move much, just lie back and relax."
We did as she suggested and I really enjoyed the sensation, it was like being in a water sauna. Sylvie was lying next to me and I felt her body touching mine. I took her hand and we smiled at each other. As we lay soaking I watched as a young Asian couple, probably Japanese or Chinese approached the pool. They looked about nervously before entering the water. To my surprise they didn't remove their towels. I looked as Sylvie questioningly and she whispered "In Japan most onsens are not mixed and when they are I think people often keep their towels on in the water."
It wasn't long before a member of staff appeared and, in my opinion, somewhat rudely shouted at the couple in German. The two of them look embarrassed and bewildered and obviously didn't understand what they were being told. The staff member shouted again and this time Sylvie intervened. She stood up and walked to the couple. "Do you understand English?" she asked.
The man was staring at Sylvie in shocked silence but the woman nodded and hesitantly said "I speak some English."
