Despite certain physical disparities between humans and the ponies of Equestria, you have found that the Ponyville gymnasium is more than capable of giving you a good workout. Sure, the stares are ever present, as is the scent of horse sweat, but it hasn't been remotely enough to stop going.

After a satisfying set on free weights, treadmill, and everything else needed to keep yourself in shape, the only thing that's left is to get your things and go. One of the other "downsides" to the gym has been the attention of mares. The common variety isn't particularly unwelcome, and it feels more just like women admiring a man, but the futanari are the ones who make your sweat a bit cooler. In her case, about 20% cooler.

The pegasus seems dead set on making your every workout awkward, offering to spot you, then doing her best to beat yours, and lapping you on the track in "friendly competition." At times, it seems like she's trying to show off, but there's a creeping sense that her focus on you may be coming from somewhere other than an irksome gym buddy.

You're pulling your clothes out of the locker when there's a groan from behind, the telltale, high-pitched and ever so slightly scratchy voice of Rainbow Dash. "Heya! Nice hustle out there. Lots of squats," she mentions, voice dripping with something far less than platonic gym buddy, "Of course, you could use some squat thrusts, if you ask me."

When you turn to confront her lewd comment, the pegasus is close, massive package throbbing as she stretches, the tomboy melange of lady's sports deodorant and feminine sweat clashing with the pungent, sexual musk over her sweaty mare cock and tightly contained balls. The lycra of her shorts strains audibly as blood flows to her long, twenty-incher, "I tell ya, dude, I am crazy horny after a workout. How about you be a good gym buddy and help a mare out?"
