Here are some of my more weird/hardcore ones. They're likely still a bit tame for gurochan.

- starvation/extreme thinness.

- unexpected pain/bleeding, and gory accidents.

- involuntary urination due to pain or pressure in the abdominal area.

- unusual methods of self harm.

- runny noses and nosebleeds.

- a lot of stuff involving teeth, most notably sharp teeth, braces, and tooth removal.

- extreme masochism, to the point of not feeling pain at all and instead only feeling pleasure.

- oddly placed and/or or oversensitive erogenous zones, and the discovery of such.

- scenarios in which a super kinky person gets a super vanilla person into their fetishes. bonus points if this previously vanilla person ends up even kinkier than them.

- "accidental" noncon, where somebody thinks the other person has consented due to grave miscommunication.

- necrophilia, but only with freshly dead corpses. bonus points if the necrophile treats the corpse with affection and adoration, just as one should.

- respawning/regeneration.

- people getting severely punished, whether they're deserving of it, completely innocent, or somewhere in between.
