Change His Parents

Peter knew he had to change his parents next. If they saw Melanie acting like this...

He saw the two of them downstairs, at the coffee table, and hit the pause button. He then pictured two fictional female characters in his mind and watched as his parents transformed into them.

First, his dad. His body warped and morphed as his skin smoothed, and body hair disappeared. His skin tone lightened, while his muscles turned into soft tissues, and his hips widened, leaving him with an hourglass figure. His penis retracted into his body, leaving him with a vagina. Impressive breasts grew on his chest, and his eyes grew bigger, changing from dark brown to bright blue. His short brown hair grew long and blonde, styling itself into a ponytail. Lingerie and stockings magically appeared, hugging his hips, and makeup was applied to his face. He was now Mercy, from Overwatch.

Peter then turned to his mother, who had turned into a sexier version of Kama from Fate/Grand Order.

Peter then hit mind control. His parents slackened before they could even react to their new bodies.

"When I wake you, you will both think you are Mercy and Kama, respectively," Peter said. "You were pulled from your own fictional worlds and brought here through a mysterious power years ago. However, you both found love in each other, married, and adopted a child. That child was me, and I have a dog named Melanie. You have never had a daughter. Oh, and you have no interest in returning to your worlds, or with fucking me. I'm not your real son, after all."

He then woke them. They turned and smiled.

"Good morning, Peter," His dad, or rather, his mother Mercy, said in her sexy Swiss-German accent. "Sleep well?"

"Yeah," Peter said. "Selena came over, and--"

"Well, we know what that means," his mother Kama said with a wink. "I'll make breakfast."

She stood up and Mercy growled. "Damn, you have as fine an ass as when I first married you."

"It's because I don't age, silly," Kama giggled. She and Mercy began to make out.

Now Peter had not one, but two hot fictional mothers.
