(short poll) Help me make a decision about an upcoming drawing :P (Patreon)

Hello, guys!

So, I'm about ready to do another drawing for that Miscellaneous Dirty Ideas bundle that I kind of started but neglected last year, haha. 

Here's the idea: Diana & Akko being dominated by the two bully girls (from Little Witch Academia)! The bullies will be playing with one girl, while the other girl is bound and gagged off to the side, forced to watch. The girl who is being played with will be unbound, but being held down in one bully's lap in a chair, while the other bully gets ready to play with their new toy ;) I've wanted to do some 'bondage' that just involves multiple people holding down another for a while now, so this is a good opportunity for that!

So! The question is! Which girl should be bound/made to watch, and which should be played with by the bullies? If you're not familiar with Little Witch Academia--Diana started off the series as the bully's friends, and the used to gang up on Akko. But towards the end of the series Diana and Akko become friends, and are often shipped together. So I guess the scenario is that the bullies feel jilted by Diana suddenly becoming friends with Akko and wanna keep being mean. It's a "couple in distress" kind of thing. I think I'll have the bullies saying something degrading to whoever they've got in the chair.

I hope you like the idea! I know LWA isn't the most popular anime but I've had this idea in my head for AGES now and I really wanna do it haha. However you vote, I hope you're eager to see the result!
