Andy clutched his stomach and collapsed onto the floor, groaning. Lilia recognized the discomfort; she experienced it the first time she took the serum. She didn’t know what to expect, especially Andy’s groans becoming feminine.
The slight stubble on his rounding, softening face vanished. His remaining body hair followed suit. His arms thinned and hands grew delicate. Narrowing shoulders served to cause his arms to cradle the burgeoning mounds on his chest, even more so when his waist narrowed. The bulge in his boxer shorts receded as his, rather, her hips widened. Her thighs gained a bit of muscle her calves lost as her feet became smaller.
“Andy! Andy are you alright?!” Lilia shouted as her feminized boyfriend was still trying to regain her senses.
“What the hell was…?” Andy said, just now noticing her feminine voice; and soon enough, her altered body. “What the fuck happened to me!?” She screamed.
“Your legs; do they feel weird!?” Lilia shouted.
“What the hell kinda question is that!?”
“Just answer it!”
“Of course they feel weird! They’re fucking girl’s legs and I’m missing something very important to me between them.”
“But you don’t have an overwhelming urge to push them together?”
”No! Why are you so worried about my legs when I’m a fucking GIRL!”
“That stuff you swallowed… it wasn’t mouthwash.”
“Yeah, kinda figured! So what is it?”
“A magical serum, you see; I’m not really human. I’m a mermaid.”
“Mermaid?” Andy said with a cockeyed expression.
“Yes.” Lilia answered. “I use that serum to turn myself human. I have to take it every 24 hours or I revert to a mermaid again.”
“So, why did it turn me into a girl?” Andy said with her arms folded.
“How should I know, I’m no alchemist. I just drink the stuff; but as I said, I have to take it every day, so it does wear off. I’ll call you in sick today and tell my boss I have to take care of you.”
“Well, that’s good; but you owe me big time, and I have a good idea how you can repay it. I seem to recall we once had a conversation about the so-called ‘mermaid problem’, that you had ‘an educated guess’ there was none.” Andy had a sly smirk on her face. “Plus, tomorrow’s the weekend so…”
“Uh, you mean…”
”You let that serum of yours wear off, then when mine does, I get to experience every man’s dream.”
“Really, I thought every man’s dream was hot girl on girl action.” Lilia said, now wearing a smirk on her own face.
“Well, I figured the mermaid thing was more realistic.” Andy said with a chuckle.
