Just as before when he'd turned her into a copy of his girlfriend Jeff watched as his mom got younger. Her hair grew out some and the lines disappeared from her face. Her breasts perked up and she lost some height as she regressed from 38 to 18. She lost the long legs, but kept the muscle tone. She even gained a little baby-fat on her hips and ass, and some dimples in her cheeks.
"Master Jeff? What did you--Oh!" the now-young slave gaped as she caught a look at herself in the mirror on Jeff's dresser.
"I'm young again! Oh thank you!" The look she gave him held so much promise that it was all Jeff could do to remember that the cute, mostly naked girl in his room was really his mother.
"So slave-mom," Jeff said casually as she began posing and watching herself in the mirror, "Tell me about your tattoo."
"I had it done after you and your sister were born," she said carelessly. "It's a double-heart with your name in one half and your sister's in the other. I had them do it there because it's supposed to hurt less on fleshy areas, and I thought only your father would see it. He liked to kiss his hand and give me a slap on the ass "for the kids" when you weren't around.--" She broke off and looked quizzically at her son.
"Jeff Honey? Why did I tell you all that?"
"Because I didn't just make you younger, earlier I changed the setting for how duplicitous you can be. I'd guess right now you wouldn't be able to keep from answering questions fully and honestly if you tried.
"Oh." She said before grinning wickedly. "Truth or dare now? Then would you like to hear how badly I've lusted after that sweet body of yours these past couple years? How often I've thought about you while touching myself?" As she talked Jeff's mother's hand slid to her waist, slipping below the filmy skirt and beginning to gently stroke her pussy.
She continued, telling her son about her fantasies as she slipped her fingers inside and began masturbating in front of him! Jeff couldn't believe his eyes and ears! Worse he was getting a raging erection from it all.
"Master?" Jeff's mom panted, her eyes locked on his bulging crotch, "May I take care of that for you? I am your slave, and it is my sincerest wish to satisfy your every desire."
"I, I guess--but I can't keep calling you slave-mom, I mean, you're my age, you won't--wouldn't have had me for a few years yet--" Jeff's stammering was silenced as his young and horny mother pressed herself against him and slipped her tongue into his mouth.
"Then call me by some other name, Master, for I wish only to be yours!" As her slick fingers teased his zipper open Jeff could barely think straight.
