cheese_grater
along with all the rest mentioned, of course. Maybe an interesting question would be things we like in porn but not in reality. I remember someone pointing out showers are very erotic for pornography but with two people it’s a fight over the hot water.
It’s literal. A cheese grater.
The Cheese Grater Image, also known as the Cheese Grater Raccoon, is a reference to a picture of Fender, an anthropomorphic ferret-fox, who has an unknown partner using a cheese grater as an instrument of sexual gratification on him. It is often regarded and referenced within the furry community as “nightmare fuel”.
It involves anal penetration and blood. So yeah, don’t want that. Either in real life or as a hentai tag.
