"From now on, you will address me as Master, boy. Do you understand?" Master snarled.
"Yes, Master." Chad replied meekly.
"Good." Master opened the door, and attached a leash to Chad's collar. He pressed Chad's face into his crotch. "Take in your Master's scent, boy. You like it?"
Chad's mind screamed at the indignity he was suffering, until he realized...his cock was rock hard. He was there for his Master's pleasure, and he LIKED it. Soon he went from smelling his crotch to licking and nibbling at it, hoping desperately for a taste. He felt his Master's hand running down his back, praying that he wouldn't invade his poor virgin ass. To his further horror, his wish was granted as Master found another hole.
"You like that, boy? I made you a nice dog pussy. You're gonna be my breeding bitch from now on." He fingered Chad deeply. "But being the nice Master I am, I let you keep your cock, too...feels good, eh? Well this is gonna feel even better."
He tied Chad to a pole, before unzipping his pants, revealing an unsheathed, and very canine looking cock. Chad yelped, and tried to run, but Master was too fast, grabbing Chad's hips, and in a swift motion, driving it home into Chad's new vagina. Chad screamed...at first. But as Master continued, his cries turned into moans, begging his M<aster to fuck him. Before too long, Master's knot pushed it's way in, tying him and Chad together, and his mutt dick loosed stream after stream into his new bitch.
