After what felt like perhaps hours more of their kissing and caressing each other or just lying happily in each other's arms Mike said that he could use a shower and something to eat. Wendy eagerly agreed with him and he offered her the first turn in the shower. They briefly discussed trying to shower together but ultimately decided that the cramped shower was too small for both of them to fit.
She sat up on the edge of the bed and finally removed her shoes and necklace from the previous night. Mike watched her naked body glide across the floor as she stepped into the shower without bothering to close the bathroom door. When she finished and stepped out of the shower to begin toweling off Mike felt his cock twitch as he watched. He briefly thought about walking over and fucking her again right there but he knew he needed something to eat and a little more time to recover so he resisted. Instead, he took her place in the shower and by the time he came out she was already dressed and waiting for him.
As they ate they discussed what they should do for the rest of the day and ultimately decided that some time in a sauna would feel great to help work out the kinks from their previous night's exertions. They asked around and got directions to the sauna after they changed into their suits back in their cabin.
The sauna was inside one of the health clubs on board so they checked in at the desk and got their instructions. He gave them the usual run down of things like not spending too much time in there and not getting light headed but the final thing he said caught Mike's attention. Almost as an afterthought he added, "Clothing is optional."
They dropped their towels outside the entrance and stepped inside still wearing their suits. Inside they found four other couples and Mike immediately noticed that all the others were naked. Nobody spoke as they entered but most of the others smiled or nodded at them. They found a place to sit in one of the corners to let the hot air loosen their muscles and relax them. After only a few moments Wendy began stirring beside him and Mike was shocked to see her removing her bikini top and then slipping off her bottoms until she sat down again completely naked beside him. He looked over at her slightly surprised as she shrugged playfully and whispered, "When in Rome..."
Mike shrugged back at her and then stood up to push off his own suit. He tossed it aside and sat down again completely exposed to everyone in the room. Ordinarily he was not keen on being this forward in front of others but he figured that he would never see these people again and he had already taken a much bigger leap than this so what the hell.
He did notice that several of the others in the room, men and women both, had either glanced or openly stared at his cock. Unexpectedly, he felt a little twinge of excitement to know that these complete strangers were staring at him. He tried to be discreet as he let his eyes scan the other naked women in the room as he paid particular attention to their exposed tits. He concluded scanning the room and his gaze came back to Wendy beside him and he openly admired her tits once again.
She noticed his stare and teased him by suggestively wiping away some of her sweat that had been running down her tits. They sat in the sauna for a while longer and watched as two of the other couples got up and left. Mike was intrigued to notice that Wendy was watching the others just as eagerly as he had been earlier.
Eventually, they decided to leave and stood up to slip their suits back onto their sweating bodies. They got out of the sauna and toweled off quickly before agreeing that some sun and swimming was what they needed.
Wendy quickly located a couple of chairs on the pool deck as Mike stopped at the poolside bar and ordered them some drinks. The pool area was actually a lot less crowded than it had been on their previous visits. It was already late in the afternoon and it seemed that lots of people were already leaving to get ready for the evening and night.
They relaxed in the sun for a while and then each jumped into the pool. They swam around and as they lounged in the water Mike wasn't shy about hugging or touching her. She had again decided to wear her new bikini that left her tits teasingly exposed to everyone's view. As they stood on the bottom of the pool in water that was just up to the tops of her shoulders Mike took several opportunities to caress her tits or her ass under the water. At one point he moved up directly behind her and wrapped both arms around her and cupped each of her tits as he pushed his cock against her ass. He had seen many other couples acting like this in the pool over the past few days so he knew that nobody would really look twice at them being so forward in the pool.
They climbed out of the pool and relaxed again as a few more couples left the pool deck. After a while longer Wendy asked, "One more swim?" Mike quickly agreed and they got back in the water. At this point there were only three other couples in the huge pool and perhaps another ten or twelve scattered in the chairs around the pool. The sun was very near the horizon and getting ready to set but it was still quite hot outside.
After lounging in the pool for a while longer Mike seized another opportunity to caress her tits under the water. Her reaction this time caught Mike by surprise. They again were standing in water that came to just about the tops of her shoulders. He had snuck up behind her and again wrapped his arms around her bringing them down on her tits as he squeezed and fondled them. Before she had just giggled and shrugged him off, but this time she spun around until she was directly facing him. Without saying a word she embraced him in a deep kiss and wrapped both her arms and legs around him. Their tongues wrestled and played back and forth eagerly as Mike felt her legs wrapping around his waist and clutching him tightly.
His hands slipped down her back and quickly found her ass as he began to fondle her eagerly. This was still the sort of behavior that Mike had seen in many other couples using the pool so he was sure that they were still more or less inconspicuous. Her next move really surprised him as she let one of her hands snake down his chest and stomach between their bodies. Her fingers found the knot that he had tied on the waistband of his suit and she quickly untied it. With a few pushes of her fingers his suit was pushed down just far enough that his quickly growing cock was able to spring out into the pool. She stroked his cock a few times until it was hard again and then she released his cock for a brief moment.
