As Jake was waiting pacing back and fourth, wondering what else to do he started to trip up over his hooves. He landed face first into the cum towel he just used recently. "Well, this isn't gonna work." He said as he spat out cum. If he were to keep like this he wouldn't be able to get anywhere without making a fool out of himself, nevermind the horse legs doing it already.
Jake staggered back to sit on his desk trying to avoid crushing his massive balls, and added "horse tail" to his change. Jake did have a bit of tail envy after all, so he thought it'd be appropriate. At least there was no pants to worry about this time so he clicked the button.
Right away, he could feel pressure build up in his lower back. A lump started protruding out the base of his spine. It grew to about three inches before stopping. After that, little hairs started growing from the base to the tip. Each hair getting longer with the same cream color around his hooves. The feeling almost made Jake release his cock from his sheath to cum, but he contained himself. He didn't want to clean up another mess. With the luscious hairs finally growing full length, his tail was complete, resting right above his furless ass. It's base was only about four or five inches, but all the hairs growing made it long enough to touch his calves. He flicked it, pleased with it's result.
"Okay. Now to test it." Jake started walking. One foo- er... hoof in front of the other. Thankfully Jake's tail balanced out all the weird proportions that came with his legs. "Alright. That's better." Jake said as he flicked his tail again.
Finally getting used to walking on his hooves Jake was wondering what he wanted to do next.
