As always thanks to my editor Cheer_Smartie526. Note: You don't have to read the stories in order, but it makes a bit more sense if you do. The reason for the affair is explained in the first episode.
*
The parking lot at the gym was almost completely deserted. The single car present was parked far from the door which usually indicated it was the car of an employee. Brad pulled into a spot by the door. Through the glass door he saw the likely owner of the lone car. Her name was Amanda. She led some of the classes Brad had taken and he had spoken to her on several occasions. He knew she was twenty nine, that she was working on a business degree and was a huge formula one racing fan.
The sound of the front door opening caused Amanda to look up from her textbook. She recognized the man walking in. He was one of her favorite members. Brad was a regular in her spinning class. Unlike most of the men he did not pick a bike in the back row so he could stare at the female attendee's asses. Brad was always in the front row and during the stand up sprints his legs could be used to teach an anatomy class. Every muscle was clearly defined, although sometime his legs were spinning so fast they were just a blur.
In the last few weeks he had become a lot more interesting. There was something going on between Brad, his wife Charlotte and another club member named Sherry. Of the three Brad was the only one that would show up alone, usually between midnight and four am. Sherry and Charlotte were regulars, but they always came with each other or Brad. Amanda knew Brad was having sex with Sherry. She had seen the two of them going at it in the pool area during one of Brad's two a.m. visits. After watching Brad fuck Sherry Amanda had locked herself in the office and stroked herself it an amazing orgasm. She was pretty sure that Charlotte was aware of what her husband was doing. She wondered if they were a threesome or if Brad was starting his own harem. Despite Brad being at least ten years older than she was he had recently been the object of her masturbatory fantasies. More than once she had watched him work out and then slipped off to a private office to satisfy herself. As she watched him approach Amanda felt her temperature rise. Brad was wearing a compression shirt and running shorts that showed off his legs.
When he swiped his card the computer display in front of Amanda reminded her that it was his birthday.
"Happy Birthday, Brad. You're in a little early, it's only eleven. I wasn't expecting you until two in the morning," she said cheerfully.
"Thank you. It's been a crazy day. I'm pretty sure I will sleep well enough tonight that I won't be making a two a.m. visit," Brad replied, thinking he was making the understatement of the year. Despite his trysts with Charlotte and Sherry he found the sight of Amanda arousing.
"About half the equipment is being replaced, that is why there is nobody here tonight. If you need any suggestions on alternate workouts just let me know," Amanda said.
Brad grabbed a towel from the counter, "I'm sure I will find something."
Amanda watched Brad walk into the deserted gym. She found herself thinking if he was five years younger and single she would have offered a special personal training session for him.
Brad found that the equipment he used was still in service and began his workout. Thoughts of Amanda kept breaking his focus. He took a few minutes to focus on her completely, hoping it would get out of his system. Before he knew it he had spent ten minutes thinking of her perky breasts and tight ass. The only muscle he was working out was the one between his legs. He decided a few sets of pull ups would put him back on track.
When Amanda saw on the video monitor that Brad was walking towards the pull up bars she decided it would be a good time for her hourly walk around of the gym. She picked up a clip board to appear official and began her 'inspection' of the facility.
At first Amanda tried to be discreet, looking down at her clipboard but watching Brad in her peripheral vision. By the time he started his second set she rationalized that he was too focused on his workout to notice her. The muscles in his arms and shoulders bulged as he hoisted his body up and down. At the top of each pull up he curled his legs against his body. Amanda could see Brad's abdominal muscles though the tight fitting shirt. It wasn't the clearly defined six-pack the younger gym rats had but it was close enough to keep her attention. Eventually Amanda forced herself to continue her lap around the gym. As she neared the end of her tour she encountered Brad again. He was doing lunges. She couldn't help but stop and watch him. His arms were still pumped up from the pull ups and now his legs were equally well defined. Amanda felt her nipples swelling beneath her shirt. She held the clipboard against her breasts to hide her arousal. She stayed until Brad finished his workout.
"Your form looks good," she said, hoping he was convinced she was there in an official capacity and not as a stalker.
"Thanks. I'm probably too old to be abusing my knees like that, but it seems like a good workout," he replied, wiping his brow with the towel.
For reasons she could not explain, Amanda lowered the clipboard. Her nipples were noticeably protruding through her shirt. Her eyes went straight to Brad's crotch, looking for a response. Much to her disappointment he lowered the towel, holding it in a way that blocked her view. She regained eye contact with him, blushing slightly at her behavior.
Braid raised one eyebrow at her blatant stare, and took a small step backwards, desperately trying to keep her from seeing the tent in his pants. "You know, I, ah, think I'm done for the night. So, I'll just...Hit the showers before I leave," Brad muttered as he turned towards the men's locker room.
