The pool/spa/gym/laundry etc. were on the fifth floor. The pool and spa were outside in like a courtyard, completely surrounded by hotel rooms. The two gyms were on either side of the pool and spa, with large window-walls looking at the spa. He went into one gym and liked what he saw. Nautilus machine, free weights, three treadmills, one of those elliptical machines, rower, ab cruncher, and the requisite TV, water cooler and towels. There was even a small locker room, without plate glass windows, thankfully. He set his stuff down on the floor near an elliptical and got on. Fifteen minutes later, all sweaty, Jack hobbled off the machine, drank five cups of water straight and wiped his face. He looked out at the whirlpool and nodded. He ducked into the locker room and quickly peeled off his soaked workout clothes and slipped on his swim trunks. He stuffed the dirties in his bag and walked outside to the pool and spa.
"Too cold for the pool," he thought as he dipped a toe in. He preferred the spa anyway. The controls were on the wall, so he set it to 15 minutes, and eased into the rapids. Just the thing for after a long flight and workout. He closed his eyes and positioned himself so the jets were pounding his back.
A few moments later he noticed the jets were pounding something else. He felt himself get hard under the water. He quickly looked around himself – no one was in the pool area but him, and all the rooms around him were still dark. He smiled and leaned back a bit, spreading his legs a little more. The bubbles pulsed against his hard cock, tossing it in every direction at once. It felt like a thousand small tongues lapping at it. He closed his eyes and let himself enjoy it.
When he opened his eyes he saw her. She was already working out on the elliptical in the gym near the spa. She was maybe 25, long brunette hair tied with a small bow. She wore a spandex running pant, clearly outlining her well-toned ass. Her T-shirt was loose and Jack wondered what she was wearing under that. By now it was dark outside and the people in the well-lit gym couldn't see out. Jack felt his cock twitch as he watched her thighs move up and down in that elliptical pattern. He watched her ass cheeks move in rhythm with the machine. He watched her arms pumping out and back. Mainly he watched her.
He looked around again and was still alone. He reached under the bubbles and couldn't see his hands. Quickly he slipped his cock out of the trunks and let the water bombard it freely. Jack moaned, feeling the tiny fingertips poke and prod his rock hard cock under the water. The woman stopped and took a drink of her water. She looked around the room and out into the spa area. Jack froze. Then he smiled. "She can't see me. She can't see my cock bouncing in the water." He wrapped his hand around his cock and stroked it a few times. "Yeah, this is fun!"
She was alone in the gym and was getting sweaty herself. Wiping her face with the towel she pulled her T-shirt over her head and tossed it on the floor. Her sports bra barely held in her tits. She rubbed herself with the towel, lingering on her breasts and dribbled some of her water on her chest. She draped the towel over the handles and started her workout again.
Jack pulled harder on his cock, enjoying watching this woman working out. Her large breasts were bouncing in rhythm to her strokes on the machine. Her ass cheeks would quiver with each revolution, and Jack enjoyed feeling his cock bob against his hand. He knew he couldn't last much longer. The woman stopped her machine and stood next to it and started to stretch. When she bent over, facing the dark spa, Jack was able to see her tits clearly. He squeezed his cock and went over the edge, feeling his cum spurt out of the water. His balls contracted from the bubbles and cock twitched madly in his hand as he watched this unknown woman lean over in front of him. He kept his hand wrapped around his cock as the water continued to push it. He had to grab it before he passed out from the sensations. Finally he let go and eased back against the side of the spa. He looked up and thought he saw the woman wink directly at him. She gathered her clothes and towel and headed out the door.
Jack caught his breath and watched her go. "She's in the same hotel....maybe, just maybe I'll see her again. After all, I'm here for four nights."
