Make her a willing subject for more programming.

Okay, let's try something new. I told Ochako, "Alright Ochako, when I call you a "Hypno Doll," you will realize I placed a trigger on you, but it will not concern you. In fact, it will excite you, for you get a thrill out of the idea of someone taking control of your actions. You still won't do things you wouldn't normally do without a trigger just because I told you to, but you will find yourself wanting to let me put more triggers on you. None of these triggers will make you mad at me, even if they embarrass you, and each one will make you crave more triggers even more. You will keep this quiet of course."

As always, Ochako nodded as the trigger sank in, and after coming to, she blinked and said, "Sorry, I think I spaced out..."

"That's perfectly fine, "Hypno Doll,"" I told her eagerly and she gasped and put a hand on her head.

"...you did something to me..." she said, gazing at you intently.

"Yes... Is that a problem?" I asked innocently.

"... strangely, no... It's weird, but I want you to do whatever it was again!" she said eagerly.

"Well, you'll have to wait. I can only do it once to the same person an hour. I can use it on as many people as I like within that timeframe though, just not more than once on each of them."

She pouted but nodded. "Alright, so I'll have to come back then?"

I nodded. "Now go ahead to lunch. And remember, this is our little secret."

She nodded and walked out briskly. I chuckled. Now, while she was yet to be my plaything, she would come back herself for more each chance she got. Maybe I should do that one for all the girls from this point on... Nah, it'd get stale, let's keep it fresh from girl to girl shall we?

And of course, it was just me and Midnight now, so perhaps I should get her a little further along, so I had her meet my eyes once more.
