The wish works (unintended consequences).

Tom opened his eyes, his lovely wife laying in the bed looking sexy with no penis. He smiled out of relief and walked closer to her, laying his hand on her thigh.

She moaned appreciatively, bucking her hips a little. She licked her lips and smiled, "I'm so horny! My dilator only does so much! I want some organic dilation." She bit her lip as Tom looked up at her, confusion entering his mind again.

"Dilator?" he asked.

She rolled her eyes. "You don't remember? The one the doctor gave me in Thailand after the sex change! You were there!"

He gulped and thought. Oh yeah. Another set of memories began to form in his brain. He could remember taking his trans girlfriend to Thailand and getting her a sex change.

'Fuck." muttered Tom again.
