"WOOOOOOOOF!" Chad yelped as the big dog knotted to him forced himself into the animal carrier flattening Chad against the floor of the animal crate.
"Whoa boy!" laughed Chad's abductor, "You're right eager to make Chad your bitch, but that crate ain't really designed for two." The voice got closer as he spoke. The guy must've climbed in the back of SUV, and was probably looking at Chad's squashed whining muzzle. Chad couldn't see the speaker as Brutus was lying on top of him crushing Chad, and blocking Chad's right eye with Brutus' jowl..
"Aw, MVP, you shouldn't be sobbing, lessen you're sobbing fer joy. You've been mounted by the county's finest training dog. When Brutus is done training you, you'll get horny for cock whenever you smell or see it. Dang, we're gonna make you a different kinda MVP. All the school's athletes will still think of you as MVP, but it won't stand for Most Valuable Player no more. It'll stand for Most Voracious Pussyboy because you will crave cock inside you all the time. I'm betting you won't be able to cum when you jerk off without a warm cock buried deep inside you. That's of course assuming you're still a male when Brutus is done wi'ya. Heh, heh!"
Who talks like that? Chad had thought it was another student or maybe a faculty member. Who else would have had a key to the field house? Wait, he might end up female? Either way the bastard who was his secret admirer was planning to change Chad the stud into Chad the cockslut.
Chad's sniffles became sobs again. The pain had subsided now. Chad was actually starting to enjoy the gentle pressure of the huge dog spooning him. The knot seemed to be a warm center of pleasure and security now. He was safe in Brutus' paws. Just the warmth of the big dog, the sound of his regular panting. Chad realized that his heart was beating in sync with the animal mating with him, even his sobs were now in sync with the wonderful monster's breathing. Brutus, Brutus, Brutus - why couldn't Chad remember who owned the magnificent beast whom Chad was now thinking of as his owner.
Whether it was the transformation from man into dog, or Brutus' unrelenting passion, Chad was exhausted, and fell asleep in the animal carrier. Brutus had knotted with Chad three times. All the while, Brutus kept Chad pinned in the animal carrier. It was Brutus' regular animal carrier, and though he had pretty much outgrown it now, the carrier still reeked of Brutus' scent. Chad couldn't think of a better scent, as he dozed off.
