Just a thought

Will grinned and told the genie his last wish: “I wish I could swap bodies with anyone I wanted with just a thought.”
“Done,” the genie said.
Will didn’t feel any different. Just then, he heard the shower start running in his parents’ bedroom next door and figured it was probably his mom taking a shower before work as she usually did. The instant he had that thought, he suddenly found himself in the shower, hot water running down his body. Except it wasn’t his body.
This body was feminine and curvy, breasts swelling from the chest, wide hips, a flat groin with the slightest trail of hair surrounding the line of a pussy, and a thick ass. It was his mom’s body.
“Gross,” Will said, a little smirk coming to his lips nevertheless. Apparently just thinking of someone else was all it took. He should have worded his wish better. Oh well. He would soon fix this.
Will thought of his old body. Nothing happened. He tried again. Still nothing. The water continued to run down his mom’s curvy body.
The genie appeared in front of him.
“I’m just saying goodbye and–” the genie began but Will cut him off.
“What the hell?” Will said. “What happened? Why can’t I swap back?”
“Oh. You never wished to be able to do it more than once,” the genie replied.
With mounting horror, Will realized the extent of his fuck up. He would be stuck in his mom’s body forever. And as for his body…
It burst into the bathroom, wild eyed.
“What happened?” His mom shouted with his former voice.
The genie had disappeared, leaving Will to explain the mess he’d made.
