Zach fixes things as best he can

Suddenly, Mia's breasts begin to shrink and so do her hips. In fact, she seems to lose about a foot of her height as her body morphs in front of Isaac. Her skin becomes more tanned and leathery as her transformation continues. That luscious flow of brown hair shrinks to shoulder-length hair that is greying, just like Isaac's mother's. That's when he recognizes the body in front of him: It was his mother.

Isaac then watches as Mia looks to her new body in horror. Tears begin to flow from her face, as Isaac says "Oh shit."

Back at Isaac's place, Zach hears a scream, which only makes him grin. He then grabs the notebook, and writes 'Switch Mia Reeves' current body with Mary Rowland's.'

As he waits for the transformation, he decides to take a few things from his previous body as well.

'Switch my penis with Isaac Rowland's current body'

Upon penning that sentence, he feels his body jolts, and then feels a large, and familiar, erection strain against his pants. Grinning, he then sees Mia enter the doorway to Isaac's room, looking just like she did before any of the swapping happened.

"What the fuck is going on?" Mia asks.

"It's me. Zach."

Mia shoots him a befuddled look. "What? But you're Isaac... What the fuck have you done?"

"It's this note book."

Zach then hands Mia the book, who reads the sentences that had been written down. To her surprise, every sentence had been a summary of everything that had happened to her so far today. After taking a second or so to think things through, she says "That fucking asshole."

"I know. AT least the fucking idiot basically gave it up right away."

"Heh. Well, it's ours now, isn't it?"

"Sure is, and we can do whatever we want with it."
