Mary quickly backed away from the table into the shadows as she watched the party unfold. She looked at the now empty vials in her hands and tried to remember which vial went into which cup. She looked up and watched as one teen, with short brown hair and wearing a simple t-shirt and blue jeans walked over to the table and picked up several of the spiked cups of beer before heading back to the bonfire several of the teens were sitting around and distributing them around.
She watched with relish as he took a big gulp of the beer. He looked down at the cup and then shrugged. Soon the subtle changes started to come over him, unaware as he continued to drink the cold beverage. She watched as the others did as well. She smiled as the others began to notice the changes in the first boy.
"Uh, Nate, you're looking a little weird," said one of the other kids.
"Dude, what's happening to you?" asked another.
"What are you talking about?" asked Nate as he set his drink down on the ground. He started feeling his face and immediately felt the fur that was starting to grow it. He stood up and looked at his arms, which were also growing the same fur, white, grey and black in spots and becoming shaggier by the second. He cried out. "Ah! What's happening to me!"
He started scratching all over as the changes continued. Mary wanted to laugh as she watched one of the inconsiderate kids continue to transform from human to shaggy dog, but didn't want to give herself away. He did seem genuinely scared as he watched his humanity slowly slip away. His clothes seemed to he getting tighter as the young man cried out until finally the seat of his pants split apart, revealing more shaggy fur. His t-shirt ripped away as well as the young man fell to all fours and his face pushed out into a canine snout.
The other teens looked down at their drinks they had all drunk from and then to one another trying to reconcile what they had just seen and if it was going to happen to them as well. They looked to one another and started to get up and move back towards the house. One remained behind to comfort the whining and distressed Nate, no longer even able to speak but now completely a dog.
"There, there, we'll figure something out," she said as she petted his head. Nate let out another whimper. He had come to the party to let off a little steam and have a little fun. He didn't want to be a dog.
One of the partygoers began to stumble and cried out as he fell to his knees. "Guys! Wait! I...I don't feel so good. I...hawwwww..."
The others stopped and looked back in shock as their friend Patrick was starting to change as well. Bristly gray and black fur was growing over his face and neck as his ears began to grow to large points as they shifted up his head. He held up his hands and watched in horror as they shifted into large hooves.
"Whaaaaawww!" he cried out as his body began to reform and change, his clothes beginning to tear away as well, revealing a body covered in the same fur as well. A long donkey tail grew out as his faced reformed and pushed out, completing his transformation as well.
"Oh my god...Patrick!" cried out one of the girls to the newly transformed Donkey as he tentatively got up on to his four legs.
The remaining teens all looked at one another wondering who would be next and what they would become as Mary continued to watch from the shadows.
