Help Finding This Comic?

I can’t find it anywhere and I don’t remember the name but I remember a lot of details. It was a story where a knight and a mage sacrifice themselves for their girlfriends and allow themselves to be taken by monsters and fucked. They’re feminized and fucked by these weird sex bug slug things that sort of mindbreak them until they’re fully sissified slaves who willingly get fucked by the monster king. Pls help I’m desperate lol
