it was in Minakonami - Futanari Androgynous. As for what it is called I still don't know as I can't read japanese. I did find Minakonami - Futanari Androgynous translated though so it was all good. I found it in my massive random collection of porn I've downloaded over my many years of porn downloading.

Not sure where you can get it off the web since Futanari Palace lost all of its stuff when the government closed down the filesharing sites. E-hentai has a none translated version of it.

attached is the only part that has anything to do with process. The rest is just sex.
