David's first client is all juiced up

David checked his schedule, the first time slot was occupied by Mrs. Cooper, she was a nice mature woman who started exercising for her 25th wedding anniversary. In the few months they've been together she had made notable progress, considering she had never exercised before, but she still hasn't reached her goal just yet. He waited for her a few minutes, surprised that the gym was still empty, he then checked his clock again, 05:10AM, it was rare for her to be late, David was about to ask Vicky to call her when he heard the door open and Mrs. Cooper arrived. She was panting and sweating quite a bit, almost like she had already started working out.

"Mrs. Cooper, good morning, are you ok? Looks like you decided to start without me." David greeted her as the older woman caught her breath.

"I'm sorry David, I don't know why but today I woke up with so much energy I tried running all the way over here. It's funny, I went to bed feeling like crap, but I've never felt this motivated before." Mrs. Cooper explained herself and surprisingly in just a few moments she looked like she had already recovered.

"Well, there's nothing wrong with being motivated but you should be careful and try not to exhaust yourself before a workout session. Did you remember to do your stretching exercises?" Asked David a little worried that she might have already run out of energy.

"No, but I'd love if you stretched my insides~" Mrs. Cooper whispered as she stared at David.

"What was that?" David asked, thinking that he must've misheard that last part, Mrs. Cooper was a happily married woman, not one on those loose girls that used to flirt with him back when he started working at the gym and they both kept a very respectful relationship with each other.

"I said no, sorry I forgot, should we start with the usual?" Mrs. Cooper corrected herself, even she was surprised by what she just said, she was well aware that David was an attractive man yet she never saw him like that, but for some reason today she couldn't help but be fascinated by his handsome face, his well-defined muscles, just being so close to him was making her heart to accelerate and her insides feel warmer.

"Yeah, you should know the routine by now." answered David and Mrs. Cooper started stretching her arms and legs. Then she bent over until she touched her feet with her hands. David wondered since when was Mrs. Cooper so flexible and her skin looked smoother and healthier. As he observed her his eyes went towards her buttocks, it looked firmer and her tight shorts made her look even curvier, he was so distracted by her rear that he didn't realize Mrs. Cooper was looking at him stare at her ass until it was too late, he quickly averted his gaze ashamed of what he just did but Mrs. Cooper just let out a giggle, feeling proud that she was able to caught his attention.

"Ok, I know you already did quite a bit of cardio so take it easy on the elliptical just for a few minutes." David instructed Mrs. Cooper after she finished stretching, he tried to not think about his previous blunder and prayed that Mrs. Cooper wouldn't accuse him of leering at her. He was unaware that Mrs. Cooper wished he would have done more than just stare, she started fantasizing about him grabbing her ass and playing with it before pulling down her shorts and fucking her. She did her best to not let out a moan as her imagination started running even wilder. That warm sensation in her insides that she felt since she arrived started growing hotter and she could even feel her pussy getting a little wet.

"Whatever you say David." She followed him to the elliptical machine, she added a little more sway to her hips trying to once more capture his attention before she stepped on the machine and started using it. She started at a slow pace but the more she moved her body the hotter it grew, that warm sensation she felt inside her was spreading all over her making her entire body tingle with pleasure. Wanting to feel even better she started moving her body faster and faster, despite her increased pace she didn't feel tired or struggling, in fact she felt like she had energy to spare and continued running on the machine.

"Mrs. Cooper! Mrs. Cooper! You're going too fast! Slow down!" David tried to stop her but she ignored him and continued increasing her pace until the machine reached its limits. Then Mrs. Cooper felt like a dam broke inside her and she couldn't control herself anymore, she let out a sexy moan and was hit by a sudden orgasm that made her stop and fall to the floor.

"Mrs. Cooper! Are you alright?" Panicked David approached the still panting woman to check on her and help her stand up.
