Years ago, I worked at a local gym as a fitness instructor. It helped me keep in shape and the view wasn't bad either. I had my share of sex-capades with the female clientele, but it was always kept it narrowed down to single women for obvious reasons. I even had a partner in crime when it came to getting information about the more secretive females. Her name was Kelly. She was another instructor who was, an on and off again, friends with benefits. I'd get her information about guys she was interested in and vice versa. This worked quite well for us, since we both tried to avoid certain types, i.e. violent and/or drug abusers.
My story starts when a couple came in for fitness instruction. I took the husband and Kelly took the wife. One of our techniques was to get to know the clientele between sets so they felt more comfortable with us and were more likely to continue with the membership. The husband's name was John. He worked in a local office all day and was a little overweight. Stephanie and John were high school sweethearts that got married soon after graduation five years ago and he wanted to lose some weight before they tried for a baby. He seemed like a nice enough guy, but Stephanie was way out of his league.
Stephanie was a petite redhead with a scattering of freckles all over the parts of her body I could see. You could tell she was the nerdy type, but she had filled out quite well since her teenage years. In her mind, she was still that nerdy girl when she looked in the mirror.
Over the next few weeks, I trained her husband and Kelly trained her. John lost a few pounds and Stephanie had firmed up her body enough that when she walked by, most of guys in the gym would steal a glance, myself included. After the latest session, Kelly caught me sneaking a peak at Stephanie. An hour later, after closing down the gym for the night, Kelly gave me a yell to help her with something in the women's locker room.
"I thought maybe you needed a little relief, "Kelly seductively whispers as she drops her towel. "I saw you trying to hide your hard on while looking at Steph. Now come join me in the shower."
I ripped off my clothes as quickly as possible and picked up Kelly and carried her to shower. She turned it on and scrubbed off our sweat before she kissed her way down to my nice hard cock. "Fuck, I always forget how big it is until I try to stuff it down my throat", she moans. She's never been able to completely throat me, but I love the way she tries. I give her a couple minutes before I grab the nape of her neck and pull her up to me. I push her up against the wall of the shower and slide in to her opening. We fuck like that for a while until my legs start to give out and she pushes me over to bench at the back of the shower. "I'm going to ride you till we both cum, you understand", she commands. I mean, who am I to argue?
"You better get ready because I'm getting close," I tell her.
"Just a little bit more. I'm getting there. Fuck. Fuck. Fuck. I"MMMMMM CUMMMMMINNNNNGGG. Oh god, I can feel you squirting in me. Oh god, it feels so good. Damn, I guess I needed that as much as you," she cries out.
We get dressed and are making a little small talk when Kelly tells me she thinks I'd have a chance if I ever wanted to seduce Stephanie. I tell her I'd like to, but having the husband always with her makes it a little hard, besides the John doesn't seem like a bad guy. Plus I don't like to mess with married women. "Well, I'll talk you up either way, just in case you ever want the chance."
The couple comes in and does their regular routine for the next few weeks, but only now when John and I walk by, sometimes Steph and Kelly look at us and giggle. When we ask what they are giggling about, Kelly just says "girl stuff" and Stephanie just blushes. Those days usually end with Kelly and I having a shower session after closing down the gym.
The next two weeks, neither of them showed. Then the third week, Stephanie showed up alone. When asked where John was, she just said he was at home, but with a little attitude in her voice. I knew not to ask any more at the time. When I talked to Kelly later on, I found out that John had been sexting with a coworker and Stephanie had found out. They had been arguing for the last two weeks and she was trying to figure out her next step.
A week went by and Stephanie came in alone again, but Kelly was off that day. I told her Kelly would be back tomorrow or I could fill in if she didn't mind. She told me it was cool if I filled in. In between sets, we made normal small talk until at one point I made a comment about John.
"So, did Kelly tell you what was going on?"
"A little, but probably not everything, "I reply.
