Try being straightforward

I figure that if the succubi meant for me to be able to conspire with Josephine, then 'Indifferent to the consequences of using the app' probably is intended to smooth over any issues with introducing it to her. So I decide to be super upfront about the App.

I went for it. "So, a couple of days ago, I found a super weird app on my phone. I've ..." I hesitate. "I've been using it, and it's been a lot of fun. But I wanted to show it to you."

"Okay, bet," says Josephine. I swallow, and turn the phone around to show her. I've got it open to Vanessa's profile.

Jo takes my phone. I brace yourself for a negative reaction, but at first she just peers at it a bit. "Custom Girls, hm?" she mutters, half to me and half to herself. "Is this meant to be Vanessa-your-coworker?"

"Yes, it is," I respond.

She scrolls down a bit. I feel something that almost feels like a pent up energy, like a fire or a blast of wind, that for some unspoken reason should be happening but for another unspoken reason is not. Josephine taps idly as I try to shake the feeling of a tiger staining at a leash just inches from her.

"So this is, what, some sort of smutty minimalist interactive fiction? Like, you pay imaginary money and it gives you prompts to imagine things you can do?"

"Not quite," I start. "The things in this app actually happen."

Josephine scoffs. "What are up up to, Jacob? Is this some sort of set-up for a joke?"

"No," I say. "Seriously. This App lets me modify the behaviour of," I hesitate, "well, just about any girl I know."

Jo looks at me sceptically. "What, seriously? Like, you activate 'Downblousing' or whatever, and she lets you look down her blouse for a while? Isn't this the girl who has a hang-up about her chest?"

"That's right."

Josephine has the weirdest smirk on her face. "This isn't really very believable, Jacob. What are you trying to do here?" She frowns. "Wait, is this some sort of kinky game you want us to play together?"

Hm. I don't know just how I hoped this would go, but this is not quite it. But maybe this is an angle I can use. "Well, not exactly. But let me show you something." I gesture for her to give me back my phone. She hands it to me, looking very skeptical. I open her profile, and show it to her.

"That's me," she says. "So you do want to play this with me." She looks up to me, not very concerned about this development, but still unsure of what I'm up to.

"Well, yes," I confess. "Now humour me, Josephine. If I were to click, say, 'Remove bra for the rest of the day', do you think you would do anything in response?"

Josephine frowns. "Maybe look at you to see what you do next. Clicking an option in some weird app doesn't seem that significant to me."

I click the button.

Josephine sits up right. "Oh," she says, and starts reaching around her back. "Um, is this really happening?"

I nod to her. "Yes," you say, as she unhooks her bra. She rummages around in her shirt, stretching her straps out of her sleeves, and then retrieves the bra from her shirt -- just as the waitress arrives with our food.
