hi /r/
Im looking for a hentai doujinshi I saw a long time ago
The story starts with a young girl who was a princess or queen (I think) who is visited by a group of men who want to make a magical experiment
They put a device on her vag (sth like a portal) that lets them fuck her without taking her virginity
nvm found it
