That evening

They both got home from work as soon as they could. They needed to get ready before the 12 hours were up. Alan got home first. He went through his drawer, but didn't find much. He had the tux, his lucky shirt he wore to Michael Jordan's last basketball game and his cap from high school and college graduation. Disappointed, he sat on the bed. He was re-reading the instructions when he heard the garage door opening, signalling that Susan was just getting home.
"That went great!" announced Susan walking in and taking off her jacket, "I got compliments on my hair. A couple ladies asked when kind of face cream I used. I think Reid may have checked out my butt. Normally, I would not like that, but it means that the medallion worked!"
"Glad to hear it went well. I'm looking over these rules, and it looks like we are in good shape. It appears that if you take if off mid change that is OK. There was more on the back about how this works."
"So, what are we working with?"
"You need to have the medallion on for 30 minutes for it to work, and then you have 12 hours from when the change is done before you can use it again. If you take it off mid change, you just get stuck in that state for 12 hours. It may work with animals, so it is a good thing we don't have pets. Apparently, if you want, you can mix and match clothing. You can swap if two people touchthe medallion at the same time for the 30 minutes. And, as you read on the front, old clothing changes you into whoever wore it last, and new clothing changes you to fit the clothing. This one is important, pregnant or menstruating women cannot change."
"Thank you, Mr legal scholar. So what should we try tonight?"
"Well, we have a few days of work ahead of us, so maybe we can touch something from way back for a couple minutes each night and see what happens by the end of the week?"
"I like the way you think."
So, as they planned, each day they de-aged a little. Alan lost some weight, got some hair back and had more energy, both for exercise and bedroom games. Susan's breasts were more perky, her ass more taunt and her abs could be seen again. She had no greys. They both looked about 5-10 years younger. By Thursday night, they couldn't keep their hands off eachother. After a passionate encounter after dinner on Thursday, they decided to call out sick and enjoy a long weekend of using their new toy.
