Finally

John woke up face down on his bed. He reached over and grabbed his phone. It was almost 10am, well past the time he needed to wait to use the medallion.
"Time to be me again!" he said getting out of the bed. He started to run to where he stashed the medallion, but with the movement, his breasts started to hurt. He wasn't going to miss that. He grabbed the trinket from the table by his TV chair, and carefully walked it into his bathroom. He placed it on the countertop, well away from anything before going to get his boxers.
Partway there, he realized he had other options. He could say goodbye to that beerbelly. He went to his box and rummaged around. He grabbed his military uniform, remembering his 6 pack and that he could run a mile in under 6 minutes. Mostly he remembered not having knee pain. The only problem was that his face would look over a decade younger.
He went back to the note and read the part about using multiple articles of clothing. What would count as "face clothing?" Would a hat do? Or maybe a mask? Sunglasses? Maybe all of them?
He finally realized this would take a moment, so he went into the bathroom to pee. He had hoped to avoid another visit to the head and having to sit, but planning took time. He finished, washed his hands and went back to his condo. After some digging, he found a cap he wore last week, some sun glasses and his mask he wore skiing. He took them all into the bathroom with his military uniform. He spread them out so his left hand was touching everything and then used his right hand to put the medallion over his neck. The felt the shock and waited.
A few minutes passed before he noted his hair shortening and changing color. His face was growing some stubble. His shoulders were definitely broader and the breasts were finally shrinking in front of his eyes. He also noted the countertop was lower compared to several minutes ago. The best part, besides losing the breasts so he could see it, was his penis coming back. He just stared at it get bigger and bigger, stopping at his previous size. He then noticed the muscles in his legs, which had not looked that large in years. He felt the changes stopped and looked in the mirror. Gazing back at him was his face averaging out at about 40 years, but his body at age 25. He flexed a few times, before he reached down to grab his dick. He had missed being able to do that. He took off the medallion, relieved that he was immune for 12 hours. Getting a ziplock bag out of the kitchen, followed by a second one, he double bagged the artifact before putting it in the bottom of his underwear drawer. Maybe it would come in handy later....
