Katie held her hand tight around the medallion and crept to the side of Megan's bed. Megan had been down for hours, and was sound asleep. Katie breathed as softly as she could, not wanting to disturb Megan's sleep. She took out from her pocket a collar. The collar had belonged to her cat, but they'd bought a new one. She slipped the collar over Megan's neck as softly as she could. She tossed, but was undisturbed. Katie then swallowed hard, like a surgeon in OR, and touched the medallion to the collar.
Megan bolted upright. She tried to scream, but all that came out was a coarse "MEOW!" Rapidly, her head shrunk, her ears perked up, and her eyes became round and yellow. Her teeth became fangs and her entire body sprouted fur. She was lucid only for a moment, staring at her hands in horror as they became paws. She tried to remove the medalliuon, but it was too late... the transformation rendered her unable to, and she mewed in anger as she shrank down to the size of an ordinary housecat.
Once the transformation was complete, Megan appeared to be a regular cat... she rubbed her head into Katie's hands for attention and purred with glee. Katie looked on in shock at the horrible deed she'd done... but her plan wasn't through yet.
She took the medallion from where the cat had lay, and put it around her own neck. She then rifled through Megan's underwear drawer for something sexy. When she found what she'd been looking for, she slipped it on and touched it to the medallion. She gasped as she felt her entire body tingle, swelling out, aging her 15 years or so. giving her Megan's form. She watched her face morph in the mirror subtlely to Megan's. Once the transformation was complete, all she could do was stare at herself for a moment, seeing a reflection she did not recognize. She practised doing her sexiest faces, which she felt was easier with someone else's face. That was when she realized what was waiting for her.
She tiptoed across the hall to Nick's room. It was decorated like a 15-year-old-girl's, but in the bed slept a nearly 30-year-old man, tossing and turning. Katie made sure to close the door loudly. Nick bolted upright.
"Whu...?"
"Ni-- Nick," Katie cleared her new throat, and repeated, trying to get used to her new voice.
"Megan?"
"Yeah, it's me."
"What are you doing here?"
Then Nick realized Megan was wearing a green silk teddy. That was weird.
"I was wrong," the false Megan said in a sultry, seductive voice, "I love you Nick, and I want to prove it to you."
She moved over to his bed and embraced him. She was kissing him passionately and he kissed her back, but stopped. "Wait, wait, wait..."
"What?" she asked.
"Be gentle... it's been 3 years."
Katie laughed a bit and slipped off the teddy. It was an odd feeling for Katie, who was naturally a virgin (although physically Megan was far from it, it was still different for Katie,) but it was stranger for Nick, who had been a girl and hadn't dreamed of doing this for the last 3 years. He was inspired, though, by how much "Megan" screamed his name.
After a voracious lovemaking sesion, after which they were both worn out, they fell asleep in each other's arms.
Of course, Katie had forgotten something...
