Jenny moaned as she felt Mike's cold nose press against her pussy. she whined a bit as he pulled away, her body was already changing rapidly. She looked down at her hands that were becoming stubby paws. Her newly grown tail wagged behind her as she felt the weight on her back. She let out a yelp as she felt Mike hop up and land on her back, she tried to say human words, but only let out a bark, but she no longer cared.
Mike panted as he felt the bitch beneath him, his red cock pressing against her spade. The smells coming rom her was confusing, he had thought she was mistress, but now she smelled like a bitch she smelled better than the one he had fucked earlier. He growled as Jenny shuddered unconsciously, he thrust into her roughly, causing her to yelp.
Jenny felt her mind turning fuzzy. The effects of the pink pill were causing her human brain to fade away. The fur was growing across her body, turning her into a golden retriever as her mate fucked her from behind, each thrust into her body sent her closer and closer into the dog mind. As Mike's knot pressed against her, her last human thoughts were of Mike, and how wonderful a dog he made. As the knot locked the two lovers together, she let out a howl, now completely a dog in mind and body.
Mike joined in the howl, he was no longer confused, this was now his bitch. He thrust in and out of her, his knot keeping them together. Anyone would find it hard to believe that the two dogs who were on the kitchen floor had been humans not that long ago. Mike humped at Jenny, her tongue lolling out as she felt herself getting filled.
Breed.
Puppies.
She needed to BREED!
SHE NEEDED HIS SEED!
The two dogs howled as Mike slammed his cock into her one last time and cum spurted out, filling Jenny's womb. The golden retriever whimpered as Mike's knot held them together, their juices mixing. Mike pulled himself out after his knot was reduced and began cleaning himself. Jenny laid on the floor, the cum leaking out of her as she did.
