Slow Takeover

"Oh, finally coming around to it?" Ivy giggled as she nuzzled against James, enjoying his kiss and touch. At first it didn't seem like James had moved the needle, but the longer Ivy had to let the thought about James enjoying her body be controlled simmer, the more it seemed to burrow deeper into her body, before she finally felt a spike of warmth pulse between her legs. The arousal bar increased, and the Lucy AI percentage was activated to 5%.

James didn't really know what 5% meant, as far as control. Ivy took a deep breath, as she shimmied her hips a little, her hand running lightly along her own thigh absent-mindedly. She didn't feel that weird, she thought, nothing felt out of the ordinary. She was just a little uncomfortable, understandable after hearing something sexy like that.

Still, the thought played in her mind, teasing at her. It really is sexy when she's taken over, isn't it? When she doesn't know what her hands might do, if they might remove her clothes, or touch her body, or touch James... the bar spiked again, and the AI indicator rose to 12%.

Ivy turned around, now feeling a little fidgety and antsy, an inkling of an idea starting to fill her mind the same way someone might be on the verge of realizing that they were getting drunk. She pushed her body closer to James, rising up a little to rest her chest closer to his face. "I don't think this is the AI, right? I'm just a little turned on all by myself... don't need a program to do this for me."

Ivy glanced down at James as she realized just how close her chest was to his face. If she didn't have all that fabric in the way, he could just kiss her breasts... would she stop him? Maybe under normal circumstances, but what if she wasn't in control and couldn't let him stop? Another jolt of arousal, and soon the Lucy AI indicator had spiked all the way up to 25%. A full quarter of her impulses were lost to her.

Ivy took a deep breath, feeling the arousal building, and realizing that indeed, as her hand started to slide along her side, as she started to position herself in front of James--who seemed to be enjoying the show by all indications--as her hips started to squirm back and forth, like she just couldn't find the right way to get comfortable again. "Mmmh... okay, this definitely isn't me. I can hold it off though, I can just push it... away... nngh."

35%. Ivy's hands were both running along her sides, from her hips up to her chest, just barely reaching the outside of her cups before she seemed to be able to will them away again. They only seemed to want to find some other place to rest, opting for her ass. James watched in increasing curiosity, and the bulge within his pants was unmistakable when he and Ivy both looked down. 40%.

Ivy's face began to change, ever so slowly. It was probably doing so the whole time, but it wasn't obvious until now. The features that looked more like Lucy started to really shine through, as her face seemed to be the average between the two, as if they shared a relative. Ivy bit her lip, glancing down. I can fight this, she thought. She thought wrong, as her struggling to compose herself seemed to only slow her movements down, but her hands went right for the crotch when James distracted her, running along her slit.

Deep within her mind, Ivy realized that she was losing the battle, and that there was almost nothing she could do now to stop the takeover. It just felt too good to have her hand running along her panties, and she moaned a little bit. 60%. "Liking what you... see..?" Ivy said, as her hips shimmied rigidly, as she reached out to take James's hands into her own, putting them on her body. Lucy's AI personality was starting to really take control now! She moaned as she felt James's fingers running along her body, her hands tugging at the clothes as she tried to avoid removing them, Ivy only able to keep them from fine-tuned control, but her arousal only grew more rapidly. 75%.

Three quarters of her movements were now dictated by the Lucy AI, and it was clear mostly in her hands and legs. They shivered and spasmed, but her hands managed to play with those buttons again, freeing her body from the confines of the shirt. How could she not resist Lucy, Ivy wondered. She still felt like she was present and in some amount of control! But it was quickly fading, as Lucy's hands--no longer really Ivy's hands--slipped out of the blouse, and deftly unhooked her bra.

The cold air hit Ivy's breasts, and she shuddered, as outwardly, she was more like a shaky Lucy than a controlled Ivy. Lucy smiled, still fighting for control as she motioned for James to start taking off his clothes, while her hands came up to play with her own breasts, giving James a show while he disrobed. She would jiggle and fondle her C-cup breasts all over, swaying her hips back and forth as she did, alluringly. Ivy, to her credit, was actually enjoying this immensely, the struggle to regain control being a part of the fun. But by now, at 85%, Lucy was the showrunner.

"Look... look at that cock," Lucy said, staring down at it as she struggled with the words. She had decent control over the body now, using her hands to slip out of her skirt, her face looking more and more like the AI to James, as she watched his member spring forth when he pulled his pants down. With only her panties in the way, Lucy swirled her body around in front of James, smiling at him. 90%. "I'm in the home stretch now," Lucy said, eyeing James--quiet, patient, obedient James. "You have to admit, I'm good at what I do. And I'm almost... almost..."

Lucy climbed onto James's lap after she slid the panties down, her naked form ready for him to touch. She made sure his hands returned to her body, letting them feel wherever they wanted, as she positioned above his cock, her slit dripping with anticipation, Ivy's body burning with desire now. 95%. 96%. 97%... Lucy touched the tip of James's dick to her pussy, and then lowered herself onto him so he would fit right inside.

"There." 100%. Lucy was now fully in control. The status indicators stayed on Lucy's forehead, so James could watch to see what was going on with her body. Lucy was fully in control, but her body was only mostly aroused. Like she was mentioning before, she the indicator was going to tell them how close she was to an orgasm, at that peak of arousal.

A good twenty minutes or so passed, as Lucy masterfully rode James's body. This AI was very adept at delaying gratification, this time not letting the mistake of orgasming just mere moments after starting the main event alter the course. However, this time, it was James's turn to arrive first--and this time, the internal Ivy realized that she wasn't going to let him cum anywhere but inside! That kind of loss of control, even as she was yelling within her own head to pull off, only shot the arousal up even higher, and she **** herself down with a sly smile as Lucy's pussy took in everything that James could give, while he sputtered and spasmed in his own way.

Knowing he was spent for a while, Lucy pulled off of James, taking a seat on the coffee table in front of the couch. She spread her legs, her fingers running between her pussy lips, pushing in, and rubbing at her clit as she moaned loudly. Her free hand ran along her breasts, and occasionally her finger in her pussy would come out and tease the inside of her mouth, forcing Ivy to taste her own body. Whether or not Ivy found that sexy, clearly the lack of control, being **** to do so, absolutely did! James was given a show as he caught his breath, as Lucy brought her body to climax all on her own, arching her body back and practically screaming out in joy at what she was doing with herself!

This wasn't the first encounter that night. Lucy was in charge, and she kept up the sexy energy even between sessions with James. She would stroll into Ivy's room, finding new clothes to try in, forcing her body to pose in attire that when utilized in the way Lucy found interesting, looked extremely sexy--not at all like how Ivy would behave. Doing things like tying her blouse in a knot to show off her midriff, or putting her in tight jeans and a sports bra, or going through her swimwear, she seemed to come back out wearing something new for James to take off again. They went at it again and again, until finally both bodies were out of energy, their drives depleted. It was amazing that either of them still had fluid left inside.

James should've gone home hours ago, but atop Ivy's bed, as Ivy's face reappeared when her arousal had finally diminished and Lucy's control dissipated, the two just cuddled together, wrapped up in Ivy's bedsheets. That night was incredible... and Ivy got to top it off with cuddling next to James, feeling comfortable in his arms and delighted that he was participating. Both of them drifted off to sleep, thinking about all the fun they would have during the weekend.
