Jon is fucked

Jon could only see things from the back end of Sadie. He watched as Sadie jumped into the van and sat down, turning Jon's view into that of the car floor. He heard his sister start the van, and felt as it drove down the road. After a while, the van stopped and Jon's view shifted to exiting the van an entering someone's house. He heard a man's voice speak "Just leave her in the basement. Hank's waiting for her."
"Alright," said Zoe, and she led Sadie down stairs to the basement. Before she opened the door, she hugged Sadie and said, "Have fun, girl." Then she opened the basement door and let Sadie through.
Jon watched from Sadie's rear as the door closed. He could hear another dog panting, then realized that Sadie was panting too. His mouth became moist and he drooled slightly. A heavy musky odor seemed to emanate from his mouth. "Damn if only I had the stone," thought Jon bitterly. He saw another German Shepherd, Hank, walk around to face Jon and began smelling and licking him. This only served to turn Jon on even more.
Seemingly satisfied, Hank rose up on two legs and mounted Sadie, his member erect and bulging. He humped Sadie's ass a fee times before his cock finally found Jon's mouth and entered it. Jon felt a rush of sensations as Hank's member slid in and out of his drooling mouth. Finally Hank rammed hard into Jon, and a load of dog seed spurted into his mouth and down Sadie's vagina. Then Hank's knot swelled up, locking his cock inside Jon's mouth. Jon could only see Hank's balls as they dangled. Jon didn't know what to think. He was being used for sex, yet he was both revolted and extremely horny. He could do nothing but sit there and taste Hank's cock and seed as it sat inside him. Minutes later, Hank's knot finally shrank and he pulled out of Sadie, who then proceeded to lick Jon's face repeatedly. About an hour later, Jon heard the door open and Zoe's voice as she led Sadie back into the van.
"Have a good time?" She cooed as she drove the van.
"...umm... yes..." Thought Jon as he slipped into unconsciousness.
