Envision a heroine. She can be a spy, superheroine, or whatever brand of cool, larger-than-life woman that works for you.

Now envision yourself as a villain. You have captured said heroine. You have stripped her of all gear and weapons, and also her footwear. And you have placed her into a specialized chair where automated restraints have locked her in place.

There she sits, barefoot and vulnerable, nervously awaiting whatever evil machinations you have in store for her. You don't keep her waiting long. In fact, you begin immediately:

You subject her to an intensive regimen of hypno-brainwashing. She cannot resist it. She succumbs completely. She will now remember, forget, think, say, and do whatever you want.

And what is it that you want? What is the reason that you have brainwashed her?

Choose from one or more of the following options below. Or, add an option that I didn't include. In either case, please share your choice in a comment.

Divulge Information

This can be an end result on its own, or it could be precursor to, or used in conjunction with Betrayal of Others. In any case, making the heroine forget that she has divulged anything is an insidiously effective way to get the most bang for the buck.

Perform Routine Tasks

Make her do anything from maid duties to errands to business transactions that you don't want to be bothered with. While this doesn't have a sexy ring to it, it is nonetheless extremely useful and practical. Of course, sexiness can be added, e.g., maid duties might involve fetish dress up. Then this might either go hand in hand with, or fall entirely under Elicit Erotic Behavior.

Perform Criminal Acts

Why chance getting caught while carrying out your villainous schemes when you can have a hapless (and possibly mindless) patsy do them for you? The more upstanding your brainwashed heroine is (or at least was before you scrambled her noodle like so many eggs), the more she will allay suspicion and allow you to get away with your dastardly deeds.

Betrayal of Others

You might engage in this simply to derail the goody two-shoes activities of the heroine's allies. It could also lead to a serial enslavement scenario, where the heroine either captures another woman for you to brainwash, or brainwashes the victim herself. How satisfying it is to make another goody two-shoes discard her literal shoes and serve you as a barefoot, brainwashed slave!

Elicit Erotic Behavior

Here's where that aforementioned fetish maid outfit comes into play. Alternatively, you might want to see specific parts or all of the heroine bared, or have her perform kinky or titillating acts either publicly, or for your own private enjoyment. This has nothing to do with practicality and everything to do with your own perverse pleasure.

Elicit Sexual Acts

This one puts the perverse-with-a-capital-P into 'your own perverse pleasure.' It also demonstrates pure evil on your part and absolute submission on the heroine's. Be prepared for much-deserved backlash if your misdeeds ever come to light...unless, of course, you can show that before she was brainwashed, the heroine already had the desire or fetish to be so controlled and made to do such things.
