A collection of らくがき帝国/Rakugaki/Delta Team's hentai flash work. I'm not sure what the group name is, I'm going by website URL (which has 'DELTA TEAM' in it), Japanese name, and the 'RAKUGAKI' that is at the beginning of some of their work. The following is the work included in the torrent:

They're kinda like interactive 'movies', where you can choose what girl to cum into and whatnot. There's always a 'back' button so you can see what the other option entailed.
