Dave and Jeff ran down the hall followed by Ben. All the doors looked the same. The doors seemed to go on and on. Finally, Ben's eyes fell on the brown and gray furred tails streaming out from behind Dave and Jeff. The tails had ripped free from the seats of their pants, leaving neat flower shaped rips around their roots. Dave's tail was coated in a deep brown fur, while Jeff's sported gray. Capping each tail was a pitch black paintbrush of fur. Ben felt something odd. They looked...funny? He couldn't stifle a giggle. But then his eyes fell on the foot long ears extending from Jeff's head....and he couldn't hold it in.
"HahahahahahhaHAWWWWWWWWWWWW Look at you two! You got tails! Your pants ripped!" He couldn't stop laughing, slowing bending, clutching his gut as a wonderful warmth seeped into his rear.
Jeff and Dave froze. "Ben come on! We've got to go!" Jeff cried.
But Ben just kept doubled over, laughing even as the warmth increased and something pressed into his underwear. The feeling was totally alien. A heat had suffused his spine, and was focused around his butt, where his tailbone had unfused, and now was swelling into his pants.
