How should the succubus make a woman her sex slave? (Patreon)

I have some planning to do for the next part of the Riley story. Eisheth will make another appearance and turn Riley's roommate into her personal sex slave. I have a few different methods that I'm bouncing back and forth on.

Note: The more popular ones that don't get picked now might show up later. Also this might depend on what the artists I commission are willing to do.
