Chapter #9

Interactive AI

    by: SpartacusDA Author IconMail Icon
Olivia tidied up, tossing the empty wine bottle in the bin and rinsing her glass. She changed, brushed her teeth, and climbed into bed. Unable to banish the memory of what she’d seen on her phone, Olivia grabbed her current book and tried to read. The succession drama in the fantasy world was not holding her attention. She re-read the same paragraph three times; but kept picturing those hands… and that belly…

Olivia closed the book, took off her glasses, and slid a hand under the waistband of her sleep shorts.

Afterward, Olivia found it easier to drift off. Yet her mind still raced. All her life, she’d been an admirer of the female form, even before she understood what those feelings were. Now she found herself picturing her friends —especially Brooke— living with that android. They were already getting lazy, and fat. Well, fat compared to Olivia herself; the Wider sisters had always been on the larger side. How much larger would Brooke get being waited on hand and foot? And why did that idea make Olivia’s nethers twitch?

***


Over the next few weeks, Olivia tried to forget about the android’s app and the revelation it had apparently caused. She focused on her work, watched her favorite shows, and rotted her brain with TikTok whenever she felt ‘unwise’ thoughts creeping in. But she couldn’t escape it. A chubby guest star would show up in a series; she’d spot a heavy coworker going to town on a second donut in the break room; or she’d find herself repeat-watching a vertical video of a cottage-core lesbian whose gingham dress was doing a lot of work.

Then one day, Olivia’s bestie stopped by her cube.

“Hey,” Brooke said.

Olivia’s eyes went wide. Brooke was dressed in her typical office skirt suit, but the muffin over her high waistband had grown to connect with her love handles, making a solid ring of chub. The skirt fit well enough, but the round bulge of Brooke’s lower belly was much more visible now.

“H-hey, Brooke. Is that a… new suit?”

Brooke turned to examine her outfit, twisting her waist and giving Olivia a quick flash of hips and round ass from her seated vantage point.

“No, I’ve had this awhile. I did have Mary adjust it a little for me, though.”

“I see.”

Olivia considered reminding her friend of her intention to eat healthier with the android doing all her housework. But the horny part of her brain —the part that wanted to see that tum and those cheeks get even bigger— kept her silent.

“I’m just headed to lunch; wanna come?”

“Sure!” Olivia saved her work and locked her screen.

***


Olivia struggled to get any work done that afternoon. She mentally scolded herself. She could have said something about the skirt.

It’s a touchy topic.

She shouldn’t have suggested the burger place for lunch.

I should be trying to be a good influence.

She really shouldn’t have ordered two appetizers and let Brooke eat all of them.

Or, at the very least, I shouldn’t be being a bad influence!

But still, that other voice —the one that told her to get on her secret TikTok account— was getting louder.

She’s an adult. She’s capable of making her own decisions.

Olivia remembered Brooke licking her lips when she’d suggested ordering dessert.

She’s a grown woman… And growing bigger all the time… Bigger, and bigger…

Olivia shook her head to banish those thoughts and went back to the email she’d been reading.

***


That night, while eating dinner, Olivia scrolled through her ‘horny’ TikTok. She hoped lusting after some pixelated women would take her mind off her pneumatic bestie. After the fourth straight video of a curvy girl lipsynching to the various trends of the week, Olivia swiped the app closed. Her thumb hovered over the Mary app. She tapped it.

For a few moments, Olivia watched the decision tree log scroll by. Unable to resist, she tapped the Live View button. The video on Olivia’s phone showed Brooke and Mikayla’s sink— Mary was doing the dishes.

“Nothing horny about this,” Olivia said to her empty apartment.

“Mary!” Brooke’s voice came through the phone speaker.

Olivia noticed some new options on the app’s interface.

They must have updated this…

“Mary’s” decision tree now presented the app user with choices. It almost looked like a Visual Novel, where the options the android’s software considered appeared as prompts. One was highlighted, and a small progress wheel spun down. Olivia watched, and when the timer ran out, the choice labeled “answer” blinked and vanished.

“Yes, Miss Brooke?”

“Would you come take my shoes off?”

She’s too lazy to take off her own shoes?

Again Mary’s choices appeared below the video:

“Go take her shoes off.”

“Tell her to do it herself.”

“Get her a snack on the way.”

The app flashed between options one and three. Olivia was fairly confident which option the AI would choose, but morbid curiosity made her tap option three. Again it blinked, and the choices vanished, and Olivia watched through the android’s eyes as it retrieved a sleeve of cookies from the pantry and walked into the living room.

Mikayla must be out or in her room; because Brooke was alone. Still dressed in her work clothes, the older Wider leaned back on the couch with her feet propped up. In this posture, Olivia could tell her friend had eaten a hearty dinner, and this probably wasn’t the first “snack” Mary had brought unbidden. She watched the android hand the cookies to Brooke.

“Oh, thanks.”

She watched the android remove Brooke’s shoes, then was presented with more prompts.

“Put shoes away.”

“Offer foot massage.”

“Give foot massage.”

Option two was highlighted, but Olivia tapped three. She watched Mary’s hands grab her friend’s tights-covered foot, pressing both thumbs into the arch.

“Wha–ah!–” Brooke’s surprised question turned into a relieved gasp mid-word.

“Is this okay, Miss Brooke?” Mary asked.

“Mmm—mmhmm,” Brooke moaned.

While the android worked, Olivia was presented with a set of choices. The timer must have matched the foot massage; because it ticked slower than the previous prompts.

You have the following choices:

*Pen*
1. "Offer belly rub"

*Pen*
2. "Offer to help Brooke undress"

*Pen*
3. "Fetch something else from the Kitchen"

*Pen*
4. Olivia closes the app

5. Free choice

*Pen* indicates the next chapter needs to be written.
