Looking for a touhou doujin in which kaguya rapes mokou and tries to get her pregnant contains some guro I cant find it anywhere please give me a link or a title

Look for it on danbooru.
If you want a similar doujin look for "S & M revenge"
It's Sakuya and China, though.]
EDIT: Look up "Hourai Ninshin"
Should give you requested hentai.
