Back at home

John opened the door to the unit and went straight to the bathroom, while Sara went to the computer room. She picked up the medallion and remembered something.
"Dad! How long did you touch the mask to this thing?"
"I don't know, 10 minutes? I felt a zap and then nothing, so I gave up," replied John while he was coming out of the bathroom.
"So, here's what I figure. Your face is only partway to whoever wore this mask last. Maybe your hair color didn't change or your nose is still more you than whoever this was. We should try again tomorrow to see if we can solve this mystery."
"But wasn't I the last one to use it? Won't it get confused? Also, let's say it does work, then I have to wait ANOTHER 12 hours before I can change my face back."
"Dad, it's the weekend, so no one will know but us. Also, you didn't wear the mask, you just touched it to the medallion. As long as you don't put it on your face, we are all set. Another thing, this this is magic and we need to try it out. QED. We've got to find out who wore this thing."
"You know, Sara, fine. If it'll make you happy I'll do it in the morning. But for now, we go to sleep. I'm tired," said John before going to bed.
"I'll take the couch, see you in the morning," replied Sara before taking off everything except her boxers and lying down. Sara was on her phone for a while before she realized she didn't hear any snoring from her dad's bedroom. She peaked in to see him quietly asleep. Closing the door silently, she was getting more excited about this medallion. Maybe it could cure diseases or problems, like her dad's sleep apnea. Maybe she could figure out how to help things like really poor vision by having the person wear glasses with less correction. On going back the the couch, she did some light jumping, feel the lack of jiggle she was used to for the last several years. She thought about other things she could do to herself as she fell asleep.
Sara woke up in the morning with an erection. She stared at her 8 inch cock, and then grabbed it. It was so much more sensitive than when she held it to pee yesterday. No wonder her boyfriends were so frisky in the morning. In for an ounce, in for a pound thought Sara as she started to stroke her new attachment. After a minute, she felt this weird sensation in her pelvis before she finished all over her boxers. It was at that moment she decided it was time for a shower. After rinsing off, she put a towel around her chest, then realized that wasn't necessary. She changed it to around to waist and left the bathroom. She started the coffee as she saw her dad leave his bedroom and head to the bathroom. It was then when she notices the clock. It was time to see who last wore the mask.
