Tough call

"It's a tough call but I think I'd like the fairy one. As much as I've adapted to being a woman I'd like to be as human as possible." Nick said. "Great, I'll the centaur" Megan said as she grabbed the medallion and went into the parlor. "Nick, come in here and bring the costumes" she shouted out to him. The bag was in the center of the table so at his size he had to actually climb onto it to get the bag. When he got it he jumped off and ran to the parlor to see Megan standing naked in the middle of the room wearing only the medallion. "Now very carefully and without touching me place the centaur outfirt on the floor in front of me" Megan requested. He did as she asked and backed away. Megan reached down and pick up the centaur outfit. At first she thought nothing was happening until Nick came up to her and she saw that although he was still her twin, he was now taller than her. He continued to grow until she came up to his mid thigh then stopped. Then she could feel her back stretching and her legs bending in impossible positions. The while process didn't hurt but it did drain her. When it was done, she lay on the floor gasping and covered in sweat. She stood for the first time on her new legs. She was a little unsteady at first, like a newborn horse, but quickly adjusted and was soon walking and finally galloping around the room. As she ran past Nick, he reached down and grabbed her to stop her from running. "Ok, my turn now" Nick said. She took off the now way oversized amulet and put it on the floor in front of nick, who was already holding the fairy outfit. "Here goes nothing" He said with a sigh as he grabbed the meddalion. Just like Megan he didn't notice any changes until he looked down and saw Megan getting larger and larger. He also noticed the ground spreaing out around him. When he was finally just a little shorter than Megan he felt two sharp pricks on his back and then the two wings he had just grown sticking out and rubbing against his upper legs and neck. "Awesome!" Megan said looking at him. "Try them out" He didn't he'd be able to but after a few awkward flaps he was first hovering a few inches off the ground then a few feet and finally he was touching the ceiling. He came back down and landed next to Megan who was watching the whole thing. "Man, I should have taken that one" she said after he had landed. "Nonsense, you're pretty cool too. In fact, I bet you're a great ride" Nick said said as he flew up just over her back and landed right on her. "Now giddy up!" He yelled, kicking her in the side. While she didn't appreciate being kicked she was anxious to run and took off. Her hair blew back into Nick's face, which he grabbed onto for balance. She ran around the perimeter of the room, then into the kitchen, and finally into the bedroom, stopping at the base of the bed, which was now over fifty feet up to them. "Do you think you could lift me, Nick" "I don't know, you look pretty heavy" He said with a laugh. "Let's see" he said as he embraced her and started to flap his wings. It took a lot of effort but soon they were rising. When he got to the bed he dropped her and she landed with a thud on the mattress. He collapsed into a heap next to her, breathing really hard. "you're stuck up here now. There's no way I'm doing that again." He said in between breaths. "I could think of worse places to be" She said as she pulled him closer to her and kissed him"
