I didn't include it because I was thinking it wasn't relevant, but since I've realised both Dumbledores are on the list -- my bulletproof kink is incest of any variety, you genuinely cannot go wrong with that. Prison fic comes a close second, or any other situation where people can't get away and have to work out how to get along/form or exist within a different type of social order.
I've also been advised to be more specific about my kinks, since a lot of them are ones people usually rule out -- more than happy to write or receive cross gen, xeno (in this case that would be non-human species or animagus pairings - I'm differentiating those from bestiality, though I've written that before so what the hell) and watersports. I like exploring power differences, though I prefer it to be situational (one in a position of authority) or informal (for consensual) or outright dubious consent than strictly by the book negotiated BDSM.
