Horseplay

Kelly hears the light sound of hoofbeats from somewhere nearby, she looks down to see a male unicorn, he stops to drink at a nearby stream.

She smiles a little, she had always found horses and even unicorns fascenating while growing up. Climbing down, she pictures a Unicorn in her mind, she opens her eyes as she falls onto all fours, her hands and feet becoming hooves as she turns into a Unicorn mare.

She trots over, bending to take a drink from the creek next to the male, she gets a glance of his cock, which is starting to slide to its full length.
