He turns to run again. You cant have him telling anyone so you decide there and then. You run at him before he can do anything and bowl him over. he falls over with an audible "oof". You look him in the eye as you pull his pants down to his ankles, leaving him naked. You pull him into one of the empty stalls along with his clothes. You say to him "sorry but i cant let anyone find out". He hits you and trys to run, but you knock him over again and force his belly onto the toilet seat. You look at his naked ass, and have a sudden idea. Instead of kill him why not just fuck him. Then he'll be too embarrassed to say anything! The man trys to get up but in one fluid motion you get up on top of him and plunge your now canine cock into his ass. He yells in pain as you start pumping his ass, all the while getting hairier and hairier. As you start to climax the man starts to moan and starts panting along with you. Your faces painlessly pushes out and you let out a howl of delight as you come into his ass. the man underneath also moans as well as his cock explodes underneath him in a spew of come. You try to pull out of him but you both yell in pain. Your cock pulls out at last and you take a look at the man you just screwed. He was a red head and was handsome. He stands up allowing his huge cock and testicles to swing lazily around. You just stare at them. They are beautiful. His testicles where the size of eggs and his cock was at least 12 inches with a thick foreskin. his cock had lots of red pubes at the base of his dick and the red her covered his testicles. As you watch his cock gets hard, growing another two inches! not wanting to miss this you take the entire cock in your newly formed muzzle. you milk this cock with your tong and fell his body shaking from your blow job. as you do so you notice that his body was growing more red hair in fact his chest was covered in it. He blows a huge wad of cum into you muzzle and sinks onto the toilet. You just watch as his face starts to elongate into a muzzle. you look down and stare as his cock seems to swell at the base. The guy finally snaps out of it and stares in horror as his cock seems to finish growing his knot and starts on a leathery sheath. his bawls become longer and his cock attaches itself to his belly. he stares in horror as his shitrt he's still wearing rips as he changes into a dog. he trys to run for it but immediately falls onto all fours. His ass start to change and a big tail pushes its way out. he starts talking and seems terrified. looking at his ass gets you horny again so you mount the guy again pounding his ass. he moans in pleasure and the last of the changes happen. As you come he comes to and you both howl... When the bathroom door opens again...
