As Dylan watched from his hiding place, naked Chad became translucent. Dylan fist pumped the air, he really hadn't expected the spell to work. He was practically naked himself, Dylan shucked his shorts and ran up behind the ghostly visage. Chad for his part was totally zoned out, and oblivious to Dylan.
Dylan stopped short and looked through Chad. He couldn't see organs, but he could see Chad's front through his back. It was like Chad was hollow glass or maybe jello. Dylan was a bit nervous about stepping into Chad, but he knew that's white he had to do.
It was an old shape-shifting spell. You tied the animal, usually a wolf with a bit of sacred string, after getting it to drink the potion, and encanting the spell. It was harder to get a naked person, but Chad was one of those by the book, follow orders sort of guys. When Dylan merged with subject, he would untie the string, which would release Chad's spirit, and give Dylan the ability to be himself or to be Chad.
Dylan took a deep breath, and stepped into Chad's shadowy body. He blinked, as he felt it merging with his body. Dylan reached with his arm, and Chad's arm moved with his. Together both hands grabbed the end of the string and pulled. It was so weird watching the double exposure hands moving. The string was free, and there was only one hand, and one mind. It was Chad's hand, and Dylan's mind. He fist pumped the air again.
"Yes! It worked!" Chad's voice exclaimed.
Damn, Chad's body felt great. It was in perfect shape, and boy was Chad horny. His hormones must be double my normal levels, thought Dylan, we're they always this high or was he just amped up by the secret admirer ruse? He hoped it was the latter, or he'd be spending lots of time jerking off.
Dylan hadn't considered what would happen to the untethered mind and soul of Chad. The book hadn't mentioned it. After all one you had the beast's body, what did the other matter to the shape shifter. The book had only talked about shifting into animals, but Dylan figured rightly that people were animals. Though maybe there was another reason that the mage who authored the spellbook didn't mention using humans?
The Chad gathered Chad's stuff, dressed in Chad's gear, and picked up Dylan's discarded shorts. Then he left the field house.
