Trent was sitting on the couch in front of the TV, wondering what to do next. He had caught 'Nate' trying to chew on the Perfect Match bottle, and took it away from her, sitting it next to his beer on the table. He wondered if Nate would get mad after 12 hours of being a dog. Considering he was acting more like a dog and didn't seem to recognize himself as a male human, Trent didn't think he would even remember it. Just then, 'Nate' came over to him and wanted to play with him, jumping on to him while accidentally knocking a dose from the potion into Trent's beer, and the potion was spilling out on the table a little. Scolding the new dog, Trent sighed as he cleaned up the mess she made, seeing the bottle only had half of the potion left. "This potion is giving me too much trouble, but it would be a waste if I just threw it away. Maybe me and Nate, when he turns back, could go find some girls or something and sneak it into their drinks. Maybe I won't use it at all, or maybe I'll just use it by myself... it would kind of troubling to have to explain the potion to Nate." Thinking on his list of ideas, he took a sip of his beer, and realizing it tasted so good for some reason, couldn't stop himself from drinking more.
"Man, that's good...," Trent muttered to himself, as he watched 'Nate' and Butch chasing each other playfully. 'Nate', deciding she was tired, trotted up to Trent on laid her head on his lap. Trent petted her, wondering if Nate was still in there, while she looked up at him into his eyes and he looked into hers. Wondering why the heck he felt so aroused, Trent tried to look away, but found he couldn't. "How's it going, Nate? You still there?" he spoke to her. 'Nate' raised her head from his lap while tilting it, and sat up on the couch beside him, sniffing at him. Trent couldn't help but stroke her, feeling so good about it for some reason. His tongue stuck out, and he caught himself panting at her. "What the heck? Did I accidentally drink some of the potion?" He studied the inside of his now empty beer can, catching glances at 'Nate'. 'Nate' sat up and licked his face continuously, and Trent couldn't stop himself from bowing on all fours and shaking his butt like a dog. A tail ripped out of the back of his pants, and his ears became pointed and slip up to the top-sides of his head. "Arooo," Trent barked, feeling his teeth become canine-like. Trent went around her and sniffed her butt, while 'Nate' sniffed his butt as well.
Panting like a dog, Trent shoved his nose into it, which was now turning into a dog's snout and his mouth grew longer like a dog's. 'Nate' howled in pleasure as Trent mounted her, growing claws out of his new dog paws, and growing black fur all over. Trent now fully turned into a dog, and kept shoving into 'Nate''s butt. 'Nate' was surprised at the disappearance of her master, but upon meeting this new dog, all she could think about was mating. They both went into climax and a knot was formed, with 'Nate' now having pups in her belly.
