Not that anon, but https://e-hentai.org/s/81582d44c1/542012-36 appears to be the CG in question. From the gallery, it appears there was only a single scene, though. I found a playthrough of what appears to be a remake for the PC98 or Windows at https://www.youtube.com/playlist?list=PLjotvIcBrLDnGdfhAC57fnn1dsqbc8qqO, but the scene doesn't seem to be there. Either I missed it, the player skipped it, or it was removed from that version.
