Lol idk about those kind of manga but there's an anime called boku no sexual harassment where the seme shoved a corn into a guy's hole bc he raped the uke
Wahaha i remember that anime. xD It was so bad. xD
I'm looking for yaoi mangas where they use food so for example it can be putting a carrot in their butt. I've tried finding some but had no luck
