Short but sweet RO Doujin. Basically, a little tentacle, a little yuri, and a few sketches thrown in. To be honest, i can hardly ever recognise which characters from the game these characters ever are, but this ones over before you figure it out anyway :). So flick through the middle of the doujin, and go from there if you find something you like :)

Here the action is for a succubus (a demon girl, for those who don't know the game) that have some tentacle fun, and a short yuri flash too. There's a few nice illustration in this doujin after and before the story. The art is quite nice, but the action is pretty short.
