When Derek saw his long term girlfriend Melissa take hold of another man he had never imagined it would cause him such ego breaking pain and also, such exhilaration. Derek was twenty-four. He was an accountant and had just started at a big consultancy in the city. He was tall and fit and still played college rugby on the weekends. He had met Melissa three years ago. She was an art major. She was skinny and cute. She had an unconventional beauty, a boyish frame, but she was lithe, and her chest was pert and sharp. She moved with grace. Her brunette hair was shoulder length. She was as much the adventurer and optimist, as Derek practiced caution and pessimism. She had a small tattoo of a howling wolf on her shoulder and had told Derek when they had met that 'I will try anything at least once.' She had said it in her crisp and sharp voice and Derek had loved her for it.
They had arrived in Berlin for a long romantic weekend. They flew into Schonefeld airport and took the metro into the city centre to their hotel near Alexanderplatz. It was cold and it was February and they had walked the streets in coats with the collars turned up. Melissa knew rudimentary German and boldly was the one who asked locals for directions and spoke to shop attendants. Derek knew more of the language than he let on but felt apprehensive about speaking it himself. He enjoyed watching Melissa converse. She was so sweet and charming, and sometimes also flirtatious. She could make even the most innocuous phrase seem loaded with innuendo. Derek had at first hoped that this was a special trick reserved for him, but as time wore on in their relationship he became accepting of the fact that this is how she treated men in general. She had most men eating out of her palm, she enabled them to hear what they wanted to.
Melissa had told Derek about an indoor swimming pool that sounded cool. It was built underground and was meant to be relaxing. They played classical music underwater. So when they set out one morning they packed their swimwear and towels in their backpacks. In the morning they had cycled around the Tiergarten and when the cold had become biting they went indoors. Over a cup of coffee Melissa casually suggested that they head down to the pool she had been talking about. Derek thought it was a great idea as they would be indoors and away from the cold.
At the front desk Melissa did the talking and asked for two robes for Derek and her. They were also given white slippers each. They were issued with instructions on how to operate the lockers and tie the key chain around their wrists.
'I will see you on the other side' Derek said kissing Melissa as they went into the Men and Women's change rooms. Derek found a free locker quickly enough but as he was undressing he noticed that he could see a woman on the other end of the change room. It took a few moments for him to twig that the two separate doors for the change rooms actually led into just the one large room. The women were on one end and the men on the other. The woman he could see was partially dressed and rubbing lotion on her legs. Derek realised that if he had been there a few seconds earlier he would have seen her completely undressed. The thought gave him a bit of a rush. Then it occurred to him that she would now have that very same pleasure with him. He was mature enough to know that she probably wouldn't even look. If she had come here before, the sight of a changing man was probably nothing new. As he got into his swimming trunks he wondered how Melissa was getting on. He wondered if she had gotten changed with some guy surreptitiously watching her. The thought was strangely thrilling.
He met Melissa on the other side. She was wrapped up in her white robbed and wore the white slippers. She looked gorgeous.
'Ready?' she asked.
He said that he was. They made their way to the pool. As they did Derek noticed that there were various saunas breaking off from the main concourse. There was a sign that said 'No swimsuits inside. Get changed here'. There were a series of lockers underneath the sign. As they walked passed there was a girl taking off her bikini briefs. They caught a flash of her bottom and smiled to each other.
The pool was down a flight of stairs and no talking was allowed. The lighting was dimmed and there was a sign saying that swimsuits were required for the pool. Melissa was quick to drop her robe and climb in the pool. She was wearing a sensible one piece speedo. Strangely demure and unrevealing Derek had observed. He floated out into the heated pool after her and very quickly felt completely relaxed.
When they had left the pool after sometime Melissa had turned to Derek.
'Do you maybe want to try one of the saunas?'
'Sure' he said eventually after some hesitation.
'Only, you realise we will have to get naked?' she was smiling at him. He could tell that she thought he would be too scared. That he would practice caution and restraint. There was a large part of him that just wanted to leave. But he was spurned on by her enthusiasm. 'We will be naked in front of other people, will you be ok with that?'
'I guess' he said 'if you are?'
'You know I will try anything at least once' she winked.
The first sauna they went to was an eighty degree dry heat room. While they had to remove their swimsuits they could keep their towels to preserve their modesty. The sauna had glass walls and looked out over an outdoor heated pool which connected to the bar across the courtyard. Despite being so on display there were several local Germans completely naked in the dry room. The men sat with their legs apart and their genitals hanging freely on display. Melissa and Derek sat towards the front and at one point an older German man had come in and stood in front of them. His genitals were at their eye height and he could see that Melissa was taking a long hard look. She turned to Derek with a modest smile her eyes wide open in a mock startled expression. Derek saw a very attractive blonde German woman climb down the stairs. Her crotch was completely shaved and he could see the deep crevice of her vagina. It went quite high up her front, higher than Melissa's, but was very attractive all the same.
