As Alan downed the vial, he noted it had fizz, but almost no flavor. "Mary, are you absolutely sure that these vials were the cause? Because as far as I'm concerned this is just sparkling water." He said, not yet experiencing the vials effects.
"I swear it was! And why did you just go and drink one after what I said!" She said, flustered by her boyfriends uncharacteristically brash decision. She was standing in front of him looking at the vial to see which one he drank, and quickly realized what was probably going to happen.
"There was only one way to see if these things actually worked. It makes zero sense science-wise so finding what it's made out of wouldn't help, so either A: this stuff is magic, or B: you're lying t- woah..." He was cut off by a strange tingling sensation all over his body. The tingling then began to get... sharper? Not painful at all, but sharp nonetheless. Alan looked at his body and saw that he had suddenly beefed up, where before he was already strong and lean, he now had a body like Captain America. He glanced around the room and was again surprised. The room felt smaller. No, he must have gotten taller.
Even after experiencing a change herself, Mary still had trouble believing her eyes. Her boyfriend had just grown nearly a foot taller and had the muscles of Superman. She couldn't help but be entranced by his new body. Her eyes glided over his whole body, Alan himself twisting and turning to get a look for himself.
"Okay... I can say for sure that we're dealing with magic" Alan said, stretching to see if anything felt wrong.
"Well, it's good that you believe me but we still have other problems..." the toy, after all, was still stuck inside of her, and she wasn't getting any less turned on, especially considering what she currently has before her.
