Well, what else would you do with a succubus that has to do what you say?

"Gaige says:-" Reality crashed into Gaige as she thought about ordering Jane to have sex with her. This was a succubus. A sex demon. A supermodel gorgeous epitome of feminine sexual appeal.

And Gaige was a lanky beanpole whose long reddish-brown hair hadn't been brushed in like two days and her hands were covered in marker stains from the map she had drawn up for DND next week and the only sexual activity she had ever participated in with another person was when she had let her middle school crush feel up her smallish breasts under the gymnasium bleachers in exchange for the most awkward date she had ever been on.

In short, she was suddenly feeling the most intense performance anxiety of her life. "I...uh..." Jane was looking up at her expectantly, her hands tracing little circles on her perfect pillowy breasts. Teasing. Inviting.

Gaige imagined the disappointed-or worse, amused-reaction the succubus would have when she took off her clothing and revealed her pale and scrawny body and cringed internally.

So. Another time for that. Maybe the next time her stupid neurodivergent brain randomly decided to act on impulse rather than rational decision making. It was funny, she had the power of the app to change women around her but the woman she wanted to change most of all was still herself...

That thought sparked an idea. Jane's customizations were all super expensive or really really specific. But she had plenty of gems still. Maybe a non-succubus custom girl would be cheaper to work with. And a great way to start small before eventually working up the nerve to finally bed the literal sex fiend giving her a somewhat bored expression.

"Ok. Ok. Getting an idea. Gaige says: When you're shrunk down I want you to act like a doll. Like a little posable figurine," Gaige said. Jane looked confused. "Shrunk?"

Gaige pushed her newly acquired hotkey on her phone and there was a "woosh!" of displaced air as the succubus rapidly diminished in size. In less than a second she went from taking up most of the twin size bed to the size of an action figure, keeping the same proportions.

She was frozen in place when Gaige approached the bed, holding her position with a glassy eyed expression. The command to act like a toy seemed to have worked. She was a lot less intimidating while she was this small, and Gaige gingerly picked her up, amazed at how much warmth seemed to flow through the succubus's hot pink skin. Jane was still unresponsive as Gaige delicately toyed with her limbs, posing her and carefully feeling and admiring the tiny demon's exquisite body. She wondered if Jane was even aware in there, if the command to act like a doll extended to her mind or merely her body. That was something she could play around with later when she experimented with the app more, first she had to cover up Jane's tiny nude form.

Fortunately she had some options. Perusing her collection of anime figurines and plushies yielded a magical girl sailor's outfit that she was barely able to squeeze Jane into. The tight little dress with its ribbons and frills looked absolutely adorable on her, paired with some thigh socks and knee boots, though the shirt ripped open a bit under the pressure of trying to contain Jane's enormous tits, but that was something she could easily fix with a bit of stitching. The important thing was just disguising Jane so she could pass for an anime figurine Gaige was carrying around instead of...well, an actual demon.

She had another idea as she moved to tuck Jane into her hoodie pocket. "Gaige Says: When I say, "Time in", you'll be able to move and act on your own again. When I say, "Time out," you'll revert back to this state. This will also work while you're full sized." This way she could access the Partner in Crime perk she had bought for Jane easily enough. It was a little vague about how it worked but having Jane help her out with choosing custom girls and perks could be handy.

"Time in," she said, testing the trigger. Jane shuddered in her hand, a moan escaping her lips as both her hands went to her cunt. "Ooo, what was that?" The succubus had clearly felt the effects of Obedience is Pleasure just from obeying the trigger phrase. After a second the tiny demoness shook her head and looked around at her surroundings, a confused expression on her face. "Did your room...change, somehow? It looks different," Jane said. With awareness off she was oblivious to her change in size. But maybe with her familiarity with the app some sense of what had happened was leaking through.

"No. All normal," Gaige responded. "I just wanted to see if the outfit was fitting you right."

Jane shrugged. "It's a little tight but I can just....shapeshift...wait..." A look of concentration melted into a look of concern, and then a flash of fury. "Oh that bitch. She locked my powers! I'm going to fuc-!"

"Wait, who? And you can't shapeshift?" Gaige cut her off before she could launch into a tirade.

"Not. Without. The App." Jane growled. Oh, she was going to get Ymyxahlia back for this. She would find a way. Even if it took millennia.

Filing that interesting tidbit away for later review, Gauge decided to revert Jane back into a doll for now that she knew the trigger worked. "Time out." There was a little gasp from Jane as another wave of pleasure flowed through her, though it was cut off as her body froze in place. Gaige tucked her into her hoodie pocket and grabbed her messenger bag. It was time to go to school and unleash the power of the app on her classmates.
