Bad ends for All

Hey was looking about and wanted to get into some lovely corruption, mind break, mind control, stuff.  Ideally leading to a bad end we can either end it there or do like save points to go back to the original adventure and continue to the next smutty encounter.

I have a few basic idea's to throw around but I would like to brainstorm with people about it either here or in ET.

Demon Lord's Harem

Demon lord is summoned by a king who's kingdom is 'overrun' with adventurers going about killing everything and stealing almost anything not nailed down.  He fears them leading a revolt just to take his stuff or take power, so he summoned me the demon lord.  Being the lawful orderly devil that I am I set up a dungeon to lure the adventurers there with promises of power and wealth, capturing them and giving them to the monsters I gathered to house my dungeon.  Or keeping them for myself if they are sexy enough, the only rule the King emposed upon me is if an adventurer with pure wishes enters my dungeon I can test them but I must do what I can to help them in their quest.  The price they pay for that quest is up to me.  (Essentially playing a devil summoned to deal with greedy adventurers, corrupting and enslaving the greedy and power hungry.  I prefer playing with the victim being female but it is far from required.  If you wanna go the pure quest route that is also fun but more corruption focused and essentially ending in a bad end of whatever sort desired from her being coverted into his devil bride or the like.)

Brainwashing Academy

The newest teacher arrived at the academy he is here to do two things, provied a quality education, and enslave the girls the principal and his other clients desire into obedient sex pots or wives depending.

(Not much here sadly as I don't have a ton in mind for it so this is more brainstormy.)

Also feel free to shot whatever idea's you want my way I love all the bad end transformation mind control stuff you can give me.
