Standalone #1 Setting/Storyline Poll

As some of you will know, for the first standalone/bonus chapter, we'll have an adult NSFW version of Artoria Pendragon as the heroine/domme in a vaguely Fate/stay inspired setting as well. Because I want to release this chapter in April, the poll will be closing on the coming Monday so that I have time to build it!

The basic premise is that on a quiet night in your apartment, you attempt to summon Artoria Pendragon as your servant. What happens next?
