Jon had an idea. It was only ten; his dad was most likely still asleep. He started to walk out of his room, and the heels by the door caught his eye. My legs look so good in those... He smiled, only partially aware of what he was thinking as he put the heels on, strutting out of his room and down the hall to his parents' room. As expected, his dad was sleeping soundly. A moment later, a blonde woman in a French maid's uniform was sleeping where his dad once was, and Jon walked out of the room, a man again. He quickly found his mom sorting out clothes in the living room. "Honey?" Jon called out, feeling somewhat foolish. "Where was that magazine you took from Jon?"
There was a long pause, and Jon was worried that it hadn't worked. Then she called back, "In our room, top drawer in my underwear drawer." He resisted the urge to pump his fist in the air as he ran back to his parents' room, feeling a pair of eyes on him momentarily but disregarding it. The porno was easy enough to find, as was the picture of a sixteen-year-old boy bending over suggestively. He looked back at his dad, committing his sleeping form to memory as he walked back into his room.
His mom burst into the room just as he said "Unswap", and his concentration was broken. She grabbed the magazine out of his hand, but not before he caught a glimpse of the new picture. His dad had replaced him. "I knew it! Your father doesn't run, and I thought you'd try something like this. Well, I'm going to get rid of this like I should have done a long time ago." She stomped out of the room before he could stop her, and was already feeding the magazine bit by bit into a paper shredder, paying no mind to what was on the pages.
"Uh, mom..." He said meekly. "Come here, please?"
She still looked furious, but stood up as she fed the last bit in, following him up to her room where a gorgeous blonde woman in a French maid's outfit slept soundly. Mom stood speechless for a long moment, finally pulling Jon out of the door and screaming, "What did you do?!"
"I was t-trying to tell you, Mom... I didn't switch Dad back yet. He's stuck. I needed the magazine to do it." Jon prepared himself for a tirade, and was very surprised when his mom collapsed into him, sobbing. He just held her there for the longest time.
