Before too long Emily arrived in a hot pink tank top and faded jeans. After exchanging hugs, a quick kiss, and a few giggles, Mary lead Emily to the living room where she had the vials sitting on her coffee table. After explaining what they were, Mary was delighted to see her friend's enthusiasm for 'trying' them.
"So, wow!" Emily said excitedly, nearly bouncing up and down on the sofa. "This is wild! What should we do?!"
"Whatever you want." Mary said waved her hand over the box. "I put a couple off to the side you might, uh, enjoy."
"Yeah?" The brunette gazed down to five vials placed away from the box. "Let's see. Hmmm."
Mary watched with anticipation as Emily carefully considered the vials laid out for her. And her eyes widened as she saw the label of a normal person pointing to a smaller person. She picked up the shrinking vial as if staring at some priceless artifact and her jaw dropped.
"Is... is this... I mean, does it do what I think it does?" Emily gaped, turning to Mary in shock.
"Only one way to find out, I guess." Mary grinned, and took the vial from Emily's hand to spin off the little plastic cap.
"Oh God. If it works..." Emily licked her lips visibly. "I've... I've always had a size thing. But... you knew that, didn't you?"
Mary said nothing, simply smiled, and took an eyedropper to the vial, sucking up a little bit of the red potion. She then proceeded to hold it over Emily's head ominously. The brunette looked up in trembling anticipation.
Mary smiled. "Let's see what it does, first. Don't want to give you too much, you know. Just in case."
"Mmmhmmm!" Emily nodded, her ponytail bobbing up and down behind her.
Mary didn't need another approval. She gently squeezed out a single drop of shrinking potion onto Emily's head. The drop hit her hair and quite suddenly the other girl was surrounded by a weird pink glow for a moment, which subsided quickly.
"Oh..." Emily gasped seconds later, as Mary watched in anticipation. She gripped the edge of the couch and threw her head back. "Oh, Mary... oh, wow!"
"What's happening?!" Mary squeeled. "Come on, tell me!"
"This feels GOOD!" Emily gasped, her hands shaking and her whole body starting to shake again. "Warm. And... and tingly. Whatever this is, it's turning me on!"
Mary smiled in amazement as Emily's nipples quite suddenly raised beneath her top. And as if on cue, Mary watched in dumbfounded shock as her friend visibly shrank. All together, all in proportion, she got an inch or maybe a little more shorter.
"Oh God..." Emily put her head down and let out a deep breath. "That was... that was intense!"
She looked over herself and marveled as she saw her looser top and jeans. She looked at Mary in shock, and Mary looked back with a huge grin. Then both girls laughed wildly and embraced.
"I shrank!" Emily laughed. "The vials work!"
"They do!" Mary giggled, kissing her friend on the cheek excitedly. This prompted the somewhat smaller brunette to raise her eyebrow deviously and return the kiss on Mary's lips. They made out on the couch for a few minutes before the clearly horny Emily broke away.
"Okay, back to business, what did I lose?" Emily stared at the eyedropper on the table.
"Like, an inch at most." Mary considered, carefully comparing her friend's size.
"Not enough. I'm taking the rest." Emily grinned, and excitedly put the eye dropper in her mouth and squeezed before Mary could do anything.
Again, Emily took on a strange pink glow before once again going into a state of increasing arousal.
"Damn, Em!" Mary blinked. "You took a good bit."
"Ooohhhh, Mary!" Emily moaned. "This feels so good. Touch me while I shrink. Please?"
Pushing her concerns away, Mary made sure she had the 'normalize' vial nearby just in case and turned to a horny Emily. In no time, the two girls were kissing and touching each other as the brunette gradually shrank. Emily let out a loud moan as she watched herself slip down to just above Mary's neck, and still she shrank further. Now Mary tenderly held her hand on Emily's chin to push the dwindling girl's face up to meet her own so they could still kiss.
