_STORY LINE_

PROLOGUE
LOCATION:NAME_1's Garage Gym
NAME_1 is in the gym waiting for NAME_2 to arrive for her workout
NAME_3 is home but at the other end of the house
NAME_1 is wearing tight yoga pants and a workout tank top with a sports bra underneath
NAME_2 arrives and they joke around a bit before starting their workout
NAME_1 notices NAME_2 checking out her ass and feels a rush of excitement knowing that he finds her attractive
She can't help herself and nervously starts to flirt a little bit, just subtly at first
NAME_2 can't believe it, but it almost seems like NAME_1 is flirting with him
He's having trouble hiding his growing erection as he watches NAME_1 do squats, her wide hips flaring out with each rep
NAME_1 can see the outline of his hard-on through his shorts and decides to be daring, saying "you really like watching my squats, huh? How many reps are you going to make me do?"
NAME_2 is speechless and a little embarrassed, but also floored that she's being this openly sexual with him
NAME_2 says "I always just thought of it as a perk of the job."
NAME_1 responds "Well I guess that's fair. I mean I do have you to thank for this body and I'm not really paying you THAT much."
