The above Sankaku link technically still works, but it doesn't seem to allow hotlinking anymore or something like that. You'll manually have to go to chan.sankakucomplex.com and search for reaper4u. You might need an account.
I don't know where to find the other video files. I think I had them saved somewhere on my NAS, but it won't turn on anymore.
There's also gallery with 111 images related to that video on E-Hentai, you can find it by searching for Mitrofania.
