At first Mary watched with excitement the expected changes. A few minutes had passed and John had become somewhat more muscular. His hair and side burns seemed slightly red and was all around looking scruffy – more like a mane. His arm hair looked lighter – like a thin layer of tawny fur. His hands were somewhat thicker and almost sported black claws. He already had somewhat visible paw pads.
Mary noticed John seemed much more … friendly? as they started to talk about people. At the bar, they gossiped about who had ugly costumes, and who was drunk out of their mind. Laughing at a joke, John clearly had sharper teeth. His nose had slightly flattened and become somewhat dark. As they talked and drank, Mary watched as John seemed more and more uncomfortable. He definitely had more muscle, but not like Mary anticipated. Glancing behind, only his butt seemed to have grown. However, Mary was excitedly waiting for her favorite change - his lion tail. She could see the bulge already forming above his ass.
Now John looked really uncomfortable, and lifted up his foot. “Dancing is sooooo much fun, but now my feet are swollen.” He pulled off his stretched size 9.5 shoe. His foot was definitely about two sizes bigger. Then he pulled off his socks. “Ooh, that’s better! I always preferred going barefoot” Mary could see his toes were thicker and almost had black claws – about like Mary’s.
“And this damn wedgie has been driving me crazy.” John pulled at his pants, and moved his butt around. This made a tear in the back of his strained jeans. He didn’t notice this. He undid his belt, and pulled his pants, back and forth. Pulling at the back of his boxers, a short tail made its way through. John **still** didn’t notice. The hole was almost where a tail hole would be, and comfortable enough for John to leave it alone. But now Mary noticed John’s ass was completely different. Not only was it much larger, it was round, fuller, and much more like hers! John now had a foot long lion tail swishing above a large heart-shaped ass. “I really need to go clothes shopping,” he laughed.
Mary had gone silent staring at John’s changes, but he was too drunk to notice. John was acting really effeminate, and Mary realized there was only one explanation. Instead of the normal lion vial, she had dosed John with her custom Vial! He hadn’t grown boobs, and as far as she could tell John still had his dick and balls. Mary wasn’t sure how to handle this situation, but she thought it was kinda hot – but how would John react.
One clawed foot dangling, the other under his knee, John looked like he was having a good time. His two foot lion tail swished leisurely behind him. He smiled at her, “Mary I know this is weird, but I think I’m bi-sexual now.”
Mary was surprised. The vial must have made John – like her – flirty and very comfortable with his sexuality.
“You’re still sexy as hell Mary, but I can’t stop looking at how hot those guys are over there.”
Mary’s boyfriend placed his hands on his butt. “All I can think about is a dick fucking my tight ass.”
He looked at her mischievously. “What do you think Mary? You wanna go get our assholes stretched?”
