Description: 

I took the long way through the mall that night just to kill time, and ended up walking into a half-forgotten antique shop I'd never noticed before. The girl behind the counter was young, gorgeous, and way too eager to sell me her "one-of-a-kind" item: a three-hundred-dollar bottle that never runs dry, filled with a shrinking potion that never quite finishes its job--not until someone finishes, period.

I thought it was a gag until she drank half the bottle right in front of me and shrank down to knee-height before my eyes. Of course I bought it. And of course I couldn't wait to try it myself, alone in my girlfriend's apartment, right before her roommate came home early from a night that didn't go as planned.

What followed was the strangest, hottest, most impossible-to-stop night of my life.

Excerpt: 

Then, she tipped the bottle and drank half of it in three gulps. She replaced the cork, then set the bottle on the counter. The bottle burped a few bubbles, and then the liquid rose to the top. Before my eyes, the potion refilled itself.

"That's . . . so cool," I said.

"You haven't seen the best part," she said, gripping the edge of the counter. I could tell something was happening—she was almost orgasmic, mouth hanging open, eyelids fluttering.

"Are you okay?" I started to get up.

"Fine, fine. It just feels so . . . fucking . . . good!"

Her words became a moan and then a giggle. And slowly, I began to notice her leggings weren't so tight. The sleeves of her shirt were covering her hands. I was too enthralled to sit on the sofa so I stood, and that's when I realized this girl who was only slightly shorter than me before, was now much shorter. She struggled to hold up her leggings but finally figured it would make a more impactful point so she let them go. I caught a brief glance at her miniaturizing pussy before the shirt fell to cover it.

"What do you think now?" she said. "Am I a liar?" She kicked her foot at me and the ballet flat flew off and zipped past my ear. Then she did the other and I caught it, then eased it down onto the sofa.

"No, ma'am," I said. "This . . . is fucking amazing."

She walked around the counter, looking up at the man standing before her. By now she was nearly half my size and still holding onto the shirt, the only thing that stood in the way of complete nudity.

"I love shrinking. It always makes the world look so cool! And you're not looking so bad yourself there, big guy."

It made me stiffen in my pants. I couldn't believe how arousing this was, to see this beautiful girl shrink.

"Is it going to stop soon?" I asked, when she was staring straight ahead at my belt.

"I took a nice swig," she said, and laughed. By now she was at my upper thigh, the shirt dragging the ground, her tiny hands holding onto it by the neck hole. "It should stop soon."

And the moment she became so small that her head was level with my knee, the shrinking stopped. She let go of the shirt and it billowed around her feet. This little lady had a beautiful body—her breasts were perfect, as was her waist and legs. She was like a living doll and I wasn't so sure how to feel.

But I certainly had a painful, throbbing erection . . .
