Before Jeff's mom could reach the computer, her clothing felt a bit loose on her.
She went to the mirror to check, and things seemed normal at first, but as she looked at her reflection, she saw herself getting younger! All signs of aging were gone! In terms of physical age, she had to be at least 30. Not only that, but she had a perfect hourglass figure, and judging by her muscles, it looked like she'd hit the gym!
She felt good. She just had to show off this body of hers to someone, and since her son was the only one home at the time, he'd have to do.
Jeff had just gotten done with the last of his chores - washing the dishes - when his younger mother came into the kitchen. "I see you're all finished." she said smiling "Good boy."
"Mom?!" Jeff asked "Is that you?" "You like what you see, Jeff?" she asked him, with a hint of confidence in her voice "I decided to slip into something more comfortable, so put on my tank-top and shorts. Now what were you doing on that computer?"
"It's a software program." he told her "I was fooling with it, and clicked on you. When you came in, I panicked, and I think I hit a random setting. Sorry mom."
"It's fine Jeff." she said, smiling "I needed this. I feel like I could run a marathon!"
"I'd still better check anyway." Jeff told her. "I'll race you there!" she said smiling, and she ran at an amazing speed! She got there first, but before she could reach the computer, she doubled over in pain! Jeff could hear her scream, and he ran there as fast as he could.
By the time he got there, there was a succubus on the floor! She had red skin, black hair, yellow irises with slit pupils, razor-sharp black claws on her hands and feet, reverse-jointed legs, long pointy ears, large bat wings on her back, a long arrow-tipped tail, and 2 big horns on her head. As she got up slowly, Jeff realized it was his mom!
"Are you okay?" he asked her. She looked at herself, and smiled. "I'm better than okay!" she said, in a sultry voice "I feel great!" she smiled, revealing sharp fangs. She then sat down at the computer, and started typing. "What are you doing?" "I'm going to make a few more changes, Jeffy!" she said, happily "And here we go!" she hit the button. "Are you going back to normal?" Jeff asked "I'm never going back to that!" she said with a wicked grin "I'm not the one who will change!"
