Staring in the mirror playing with his new doggy ears and wagging his tail happily Mitch felt Reg sniffing at his groin region again. Feeling the sexual need to be mounted again Mitch tried not to submit to his mate... err Dog again.
But Reg would not be denied as he tried mounting his master, pushing both Mitch and the mirror to the floor. Now on all fours Mitch can't hold it any longer and presents himself to Reg again. Fully erect Reg thrust his doggy cock into Mitch for second time. With each thrust Mitch gives in more and more to his mate even as his own cock become erect.
Panting uncontrollably with the rhythmic thrusts of Reg, Mitch could see in the fallen mirror that his mouth and nose were beginning to stretch away from his face. They grow with each passing thrust until they finished into his new collie muzzle. He saw in the mirror that it was a creamy brown on top with a white underside and his wet black nose. "I hope that Reg likes my muzzle" Mitch thought to himself as Reg continued to thrust into his new bitch.
With his thoughts in sexual bliss Mitch was snapped back to reality by a knock on the door. "Hey dude are you all right in there, we keep hearing strange sounds?" asked Tom. With his tongue hanging out of his mouth and trying not to yell out in pleasure Mitch answers "I'm suddenly not feeling too well."
"Well the game is over, how about we take you to see a doctor." Tom offers.
"No, I'm just going to stay in home and sleep it off." Mitch manages to responds while panting even harder as Reg continues to thrust into his doggy pussy. "OK" Tom replies.
As the last of his friends left Mitch felt with great pleasure as Reg inserts his big knot with one big thrust, sending seed straight into Mitch's bitch womb. With that Mitch yelled in orgasmic pleasure then collapsing to the floor with his mate still tied to him.
After a little while Reg released his knot from Mitch and laid down long ways in front of Mitch. Wanting to make his mate feel good as well Mitch starts to lick Regs' cock clean, as both he and Reg drifts off to sleep.
