Half pint

"I wish Jess was half her current size", Chrissy said.
"Very funny", Jess replied as she felt a chill run down her spine. Just then she started to feel her bed expanding beneath her and her feet were no longer touching the floor. Looking to her friend she said nervously, "Whatever the trick is it's not funny" just as the feelings stopped and she was sitting in the middle of her bed with her legs straight out in front of her but her feet didn't even reach the edge.
"No trick, like I said it's magic" Chrissy said as she knelt down to face level with Jess and held one of her tiny feet in her hand. "This is awesome, you're so small" she said while holding the foot between her thumb and index finger. Jess instinctively tried to pull away but in her shrunken state even though Chrissy wasn't trying to hold her too hard she was just way too weak for to get free.
"Come on, let me go and fix this" Jess pleaded as Chrissy dropped her foot back onto the bed and flopped down next to her. The impact sent Jess bouncing what felt to her like a few feet into the air. Chrissy laughed as she landed and fell on her back and quickly surrounded her with her arms. "But how can I fix this? magic doesn't exist." she teased.
"Ok fine, it exists. Just please fix me."
"You're no fun" Chrissy said as she picked up the rock from the night stand and got ready to make the wish to restore her friend.
"That's easy for you to say, you're not the midget. Shit, I'm not even a midget, midgets are at least over three feet tall. I'm a fucking primordial dwarf!" She said while standing up and realizing that even standing she only came up to Chrissy's chin while she was sitting on the bed.
"Don't be such a baby" Chrissy said, looking down at Jess. "Besides, I've never seen a primordial dwarf as hot as you" she added, playfully slapping her ass with two fingers. "But if that's what you want, ok. I wish..." when she suddenly sneezed and dropped the rock. It hit Jess right in the chest, knocking her down and landing on top of her. At her reduced size it was a shock but it didn't hurt her. Thinking quickly she said, "I wish Chrissy was a foot shorter than I am"
