Sure!

"Sure!" you say.

"Cool!" she says and flashes you a smile that makes her face light up and your cock jerk. "I'm Ashlyn, by-the-way"

"John" you say.

"Well John," says Ashlyn removing her legs from the machine and standing "Why don't you warm-up on the bike while I finish my sets here?"

You decide to do as she suggests and walk over to the exercise bike. As you do you look out the window onto the moonlit swimming-pool and see three young women enjoying a midnight dip. You turn around and hop on the bike facing the machine Ashlyn is using and get a wonderful view of her lycra-clad ass as she bends over to adjust the weight.

You quickly divert your eyes from her divine posterior as she straightens up, turns and sits down facing you, her legs on either side of the bench of a leg curl machine which doubles as the seat of the 'chest fly' machine and begins her sets, opening and closing her arms in front of her face and chest. Even though she has a look of intense concentration she continues to smile pleasantly at you.

Even though you are quite happy to continue looking at her face you find the temptation to lower your gaze for a moment to check out her perfectly firm breasts growing overwhelming. The opportunity comes when she starts closing her eyes near the end of her third set in a concerted effort to finish it. You look down for an instant and swear you can see her nipples outlined against in the fabric of her top. You are so shocked that you forget to return your eyes to her face and, by the time you do, she has her eyes open and is looking straight at you. Instead of getting angry and accusatory though she raises an eyebrow inquisitively as if asking "You like?" You quickly switch mental gears from 'apologising' to 'agreeing' and nod making her smile appreciatively and increasing the pressure in your pants.

She stands up and turns around to change the weight again; giving you another look at her heavenly behind. This time you don't feel so guilty about looking, though, since she seems fine with it. She then lies down on her front, with her lovely butt toward you, to do her leg curls. You continue to enjoy the sight until you realize that if you don't stop soon you are going to have an obvious tent in you pants when you get off the bike and while Ashlyn doesn't seem to mind you looking at her fine body she might feel a little unsafe so if she saw the effect it was having. You therefore try to block the sight of her incredible rear and the push away the memory of her body. By the time Ashlyn finishes her leg curls you have managed to reduce your erection to a point where, you hope, you can get off the bike without it being too noticeable.

"O.k." she says turning over again and standing up "This is where I need you."

You get off the bike and follow her to a weight bench, only checking out her rear once, and has you help her set up the weights before lying down. You stand at her head, conscious of the fact that her head is now close to your groin, you will be looking toward her lovely breasts and she only has to look back a little to see your developing arousal.

As she takes the bar off its stand, lowers and lifts it you again notice the outline of her nipples in the fabric of her top and realize she is probably not wearing a bra. You also notice that they are becoming more defined and more erect. You find yourself becoming more erect too, and wonder whether Ashlyn is aware of her hardening nipples and whether she is embarrassed, although she isn't showing it.

She finishes her sets and you help her lift the bar, her arms tired. She sits up, her nipples still obviously hard against her top and asks if you want her to spot you. You decline, worried that your own hardness will be too obvious if you lie down. For some reason you feel like you did in middle school when you got a spontaneous hard-on and felt the need to hide it, worried that people would make fun of you and the girl you liked would think you were a pervert or something. It is then that you realize who Ashlyn reminds you of. She is like the girl you used to fantasize about in middle school, but physically closer to your idealized version of her than the girl herself was and personality-wise she is totally different.

"O.k. then" she says "Would you mind helping me with my stretches?"

"Of course not" you say and she leads you over to an open piece of floor, grabs a mat and lies down. She goes through her stretches, using you to hold her legs and keep her balance when necessary. It strikes you that she actually doesn't need you for any of this, that she could easily use the machines to balance and such, and you wonder if she is using it as an excuse to have you touch her and to impress you with her flexibility. If so, she is doing a very good job for, while she does not seem double jointed, she is still more flexible than any woman you've ever seen who was not.

As she finishes up her stretches with what can only be called a lying leg splay and stands up you think you notice a small patch of moisture between her legs. "O.k. thanks, John, that was great. I guess I'll go and join my friend in the sauna. You should come over once you've finished. I'm sure my friend won't mind." She walks off through the door to the female change-rooms.
