Jason makes Beth receptive

Jason tried not to look disappointed as he turned back to the computer. He wanted to argue, to suggest that maybe she could keep her magnificent cannons for a little longer, but he couldn't come up with a convincing reason other than his own perversion. He clicked the slider beneath the Breasts tab and dragged it back to the left, watching the 3D model's chest deflate on screen.

In his peripheral vision, he could see Beth's massive mounds shrinking down in real time, the sweater growing loose around her chest as the volleyball-sized tits receded like a tide pulling back from the shore. She let out a small sigh as the weight lifted from her torso, rolling her shoulders once the process was complete.

Jason kept his face as neutral as he could manage, but his dismay was palpable. Those enormous, impossibly round breasts squashed inside a sweater on his mother's slender frame had been seared into his brain, and every fiber of his being wanted to see them again.

Jason had a casual fling with a girl in his class a while back - an athletic young woman who surprisingly made the first move on him. He wondered if she might be more receptive to sporting some massive knockers. But she wasn't in his class anymore. Linking up would be awkward let alone getting her to come over and then explaining that his mom's computer was magical.

No, that was a problem for later. Right now he needed to play it cool and find a way to convince Beth to make her boobs huge again. Or better yet, find a way to make her want huge tits.

"There," he said, his voice steady despite the cogs turning inside his head. "Back to normal."

"O-kay! Let's see what else this thing can do." Beth vibrated with excitement.

Then, as if on cue, her stomach let out a loud, undignified rumble.

Beth pressed a hand to her belly and laughed. "Oh, jeez. Okay, maybe I need to eat something first before we dive in."
"I'm gonna throw some pasta on. You want anything to drink?"

"Just some water, please," Jason said, not taking his eyes off the screen.

"Alright. I'll only be like two minutes." She paused at the doorway and pointed a finger at him, her expression shifting to mock-serious. "Don't do anything crazy 'til I'm back!"

"I won't," Jason lied.

The moment her footsteps faded down the hallway, Jason turned back to the computer with a new intensity in his eyes. His heart was hammering. He knew he shouldn't, but the image of Beth's enormous tits swinging and jiggling in that sweater wasn't going to leave him alone. He had to find a way to make that happen again.

He started clicking through tabs, scrolling past sliders for height, weight, and bust size.

Then he found it. A button labelled "CMD". When it was clicked, a rectangular black text box appeared at the bottom of the screen underneath Beth’s 3D model.

Jason dragged the mouse over to a little icon with a question mark at the box’s border, and he muttered the short description that popped up under his breath. “Whatever you type out, the Subject will immediately feel or become after pressing the ‘Enter’ button.”

Jason's mouth went dry.

He stared at the blinking cursor for a long moment, his mind racing. This was it. This was how he could make it happen. He just had to choose his words carefully. He thought about it for a full minute, his fingers hovering over the keyboard.

Then he quickly typed:

[Beth loves having an exaggeratedly attractive figure and she is strong enough to comfortably support breasts of any size.]

He read it back to himself twice. It didn't force her to do anything, it just nudged her preferences. It made her want it. And the strength would mean that even if she went huge, she wouldn't be toppling over or complaining about back pain. It was perfectly simple.

Jason heard his mom's footsteps returning.

He hastily hit Enter.

The text flashed and then disappeared.

Jason returned to the main sliders. His heart was still pounding, but his face was composed when Beth walked in.

"Alright!" Beth announced, carrying a glass of water for him and what looked like a half eaten piece of buttered bread for herself. "Pasta's on the stove. Should be ready in about ten minutes." She took a bite of the bread. "So," she said, chewing thoughtfully. "I was thinking."

"Uh oh," Jason joked, taking the water glass.

Beth rolled her eyes.

"If I'm trying to attract guys, I'm gonna need a guy's perspective, right? I mean, I know what I think looks good, but I don't know what men think looks good. You know?"

Jason blinked. "Sure you do."

"Yes I know, big boobs and big ass - but I mean more than that. I need the little details too, the stuff that only you boys know to look for."

Jason said nothing.

"Come on, you're a healthy young man. You know what looks attractive. Just - make me hotter. Make me the kind of woman that turns heads when she walks into a room. Please?"

"Alright. I shall shoulder this burden." Jason joked, trying to hide his excitement.

Bethany bounced on her heels happily.

Jason set the glass down and turned back to the computer, his mind suddenly very busy.

"Okay," he said slowly, flexing his hands. "Let's see."

Naturally, he started with Beth's breasts. He bumped the slider up several cup sizes - not to the ridiculous extremes they'd explored earlier, but enough to boost her from barely-a-B to a solid, perky D. On screen, the 3D model's chest swelled outward. Out of the corner of his eye, he saw Beth's sweater shift as her real body followed suit.

"Ooh, nice," she murmured, glancing down at the new swell of cleavage pushing up from her neckline.

Next, he found the age slider. Beth was thirty six. He dragged it backwards, watching the number tick down until it settled at twenty nine. The changes were subtle. Smoothing of the skin, a tightening around the jawline, a brightness in the eyes.

Beth sighed approvingly as she felt years of aches and pains melt away.

Jason moved on to her lower body. He found the slider for her glutes and nudged it to the right, giving her ass a rounder, fuller shape. Then he trimmed her waist down a notch, slimming away the pudgy softness that had accumulated there over the years.

Scrolling back up, he increased her muscle tone a tiny bit - just enough to give her a subtle firmness beneath her skin.

Next, he flared her hips outward, widening them to create a more dramatic transition from her new, narrow waist. Then, to keep her proportions balanced, he thickened her thighs to match, giving them a soft, sculpted fullness that flowed naturally from her hips.

Finally, he found the height slider. Beth was five foot flat - petite, to put it kindly. He dragged the slider upward, adding an inch at a time until the 3D model stood just over six-foot-one. Beth's body followed suit, surging upwards inch by inch as the slider snapped to each notch.

"Whoa, that feels.. weird." Beth remarked as she pulsed taller.

Jason turned around to watch as she grew the last few inches.

"There," Jason said, leaning back in the chair. "Done."

Beth ducked into the adjoining bathroom to examine herself. Her sweater had ridden up slightly, exposing a sliver of her now-toned midriff. Her leggings clung to legs that were longer, shapelier, and more substantial than they'd been ten minutes ago. She looked down at her hands - they seemed the same, but everything else about her felt different. Taller. Leaner. Curvier in all the right places.

"Not bad!" Beth said, grinning at her reflection. She turned sideways and arched her back slightly, admiring the exaggerated curve from her chest down to her hips. "I like what you did with my hips!"

She returned to her office, leaning against the door frame in a seductive pose. One hand rested on her flared hip, her body tilted to emphasize the dramatic inward curve of her waist and the outward swell of her hips. Her new D-cup breasts pushed against the white sweater, creating a soft but undeniable cleavage line that hadn't been there before.

"The hourglass look suits me, don't you think?"

Jason's throat tightened. "Yeah, Mom... it does."

Beth held his gaze for a moment, her smile shifting into something sharper. Her eyes narrowed.

"But you're holding back on me, aren't you?"

Jason's eyes darted away from hers. "I don't know what -"

"I saw how you looked at my giant breasts before. Why are they smaller now?" Her voice was warm but firm. She crossed her arms under her new breasts, pushing them up slightly. "Tsk, tsk." She shook her head with a disappointed click of her tongue. "Go and finish up the pasta before it boils over. I'll sort this out myself."

Jason's stomach dropped. There was no telling what havoc Beth might wreak if left to her own devices.

"Mom, wait. Maybe we should talk about this."

"Shoo." She waved him off with a flick of her wrist, already pushing past him toward the computer. "Pasta first. Then you can have another turn."
