They woke around an hour later, as naked humans with Jimmy's dick still inserted snuggly between Petula's butt cheeks. Jimmy's slight wriggling roused his mate. Petula woke and was quickly assured that she had not just experienced her craziest dream ever. She smiled at the boy resting on her back.
"Comfy?" she said cheekily.
"You have no idea. I could lay right here forever," replied Jimmy. He gave Petula an affectionate peck on the cheek. Petula slightly wiggled her ass to Jimmy's delight.
"So," Jimmy began with a smile, "how did I compare to your last mate?"
Petula gave a snorting laugh: "Top marks, my lovely boar."
She quickly changed the subject: "Alright, I feel like I'm owed some sort of explanation at this point."
"Honestly, I don't think I know much more about this then you do. I started to think about you as a pig, and then it just sort of happened," Jimmy responded.
"Me as a pig, huh? What ever made you think that such a pretty girl like me could live as such a disgusting animal," said Petula with faux outrage.
Jimmy answered truthfully about his fetish for the first time in his life: "Well nothing could be further from the pretty, athletic, Petula than a fat, dirty, sow. Although you do have a spectacular fat butt." Jimmy wriggled his dick with Petula's ass.
The pair laughed and Petula farted lightly to solidify her acceptance of Jimmy's chosen animal for her. Jimmy didn't mind, baser bodily function were fairly arousing for the pair now.
"Now that you mention it, back when you were a pig the first time, you mentioned Circe. You know, from the Odyssey? I feel like she might have something to do with my new powers," said Jimmy.
"Oh. That was something that Gore - my other boar - had mentioned. He said that apparently has happened before, humans turning into animals. We only think of it as myth," said Petula.
"I guess we'll have to figure it out," replied Jimmy. "Can't say it isn't fun though!"
"Well, we certainly won't figure it out by lying on this bathroom floor. I know you find my fat ass very comfortable, but do you think we could get up. I'm starting to get numb here," said Petula.
Jimmy decoupled from Petula's butt and the pair began to get dressed. As Jimmy put on his clothes, his eyes wandered over to Petula, who was grabbing her spare volleyball uniform from her backpack. He wondered if animals were the only types of transformations he could induce. A moment later, he got his answer.
"Jimmy! Is this you?" Asked a nonplussed Petula. Jimmy turned and she gestured down her body. It had worked. Petula now sported bigger breasts, wide hips, heftier thighs, a little belly paunch, even her upper arms carried some extra weight, and her camel toe was clearly visible. Needless to say, her volleyball uniform was incredibly tight on her now.
"I wasn't a twig before, but I know I've never been this thick," stated Petula.
"I like my girls a little meatier. C'mon, lets see the rear view," said Jimmy.
Petula turned. Her spandex shorts outlined every inch of her expanded ass perfectly. Jimmy walked up amd gave her right butt cheek a firm squeeze.
"Trust me," he said, "you look much better this way." And with that, the couple exited the bathroom and found themselves in the larger building.
