Erotic story MF

We have seen each other in passing at my work on multiple occasions, we both give the polite head nod of acknowledgment to one another. But today felt different.. I’m a gym instructor in a local gym and you’re a regular customer.
You’re roughly 5:7 in height, long fair hair and flawless skin. Your legs seem like they go on for days,leading to a hard earned perky bum and your breasts are a lovely 32B cup. Overall, a very womanly figure of a person.
I’m a 6ft tall dark haired guy who has narrow hips, naturally wide set shoulders with a set of pecks that love to dance. Muscles in all the right places.
