Jon hadn't thought about it when he made the wish, but he realized that keeping track of all the swaps could get very, very, complicated. First, he had swapped most of his mother's clothes and body with the model in the magazine. Then he had swapped his shorts and penis with his mother.
If he figured this right, then
-- he had the model's suspender shorts, hips, and pussy
-- his mother had his shorts, hips and penis, and most of the rest of the model's clothes and body
-- the model had his mother's body
Doing an unswap would get himself back, but he'd have to unswap his mother and the model first. He rushed back out and looked for his mother, only to see her driving away outside. She must have come home only to get something and had to leave again. How could he do an unswap with someone who wasn't there?
Maybe there was a way, realized Jon. He didn't really swap with a model, after all. He swapped with a picture of a model. Surely there were some pictures of his mother around. If he had guessed right, he should be able to unswap the picture of the model and the picture of his mother.
Jon looked around the house for a picture of his mother and found one in the living room, in a frame. The picture had changed--it now showed his mother wearing pants like a pair Jon had, but with a top half that was shaped a little differently... it must be the top half of the model. When things changed so there was nothing out of the ordinary, it changed the past too, or at least records of the past. She must have been wearing Jon's pants when the picture was taken.
Jon held that picture next to the picture of the model with his mother's body, and said 'unswap'. His mother now had normal clothes on and looked normal. The model was wearing his mother's top, sort of--she was stripping and it was clear she was stripping down to the model's bare breasts. The model also had on Jon's pants.
Which left his mother normal, him with the model's suspender shorts and pussy, and the model with his penis... and some duplicate clothing floating around because he had used the pictures to swap different aged versions. He could swap back with the model and have an extra pair of pants and a missing pair of shorts. But he didn't want to do that yet; after all, the whole point was to experiment....
