"I'm not your mate," Katie gasped, realizing she had just had sex with her bestfriend. How could she have done such a thing? Even worse, they were stuck together like this!
"Don't be mad, Katie," Tiff whined, nuzzling her. As Katie went to reply she made a dog like whine, causing her to cover her mouth. Tiff wagged her tail, watching as Katie was beginning to change, her ears moving to the top of her head and changing into dog ears. "Katie is changing too! We can always be mates!"
"No..." Katie moaned as she felt the changes begin to take place.
