Rainbow Dash loses a bet to Applejack, like she always does in these kinds of fics.

Now she has to go to the gym and do her usual workout routine in the nude. With all the stallions watching her.

Too bad Rainbow Dash is obscenely self-conscious about that kind of thing.

Note: Takes place in an anthro universe where wearing clothes is the norm. Otherwise this fic would lose it's point.

Heavily inspired by an image series drawn by Jay van Esbrook (lil-mizz-jaye on Tumblr), which a quick Google search can find you.
