it's not fruitsjam, rather a-line.

@Red_Piotrus:
the first link is the circle's (a-line) webpage. if you click the fourth link on the left and scroll down a little, you can see this doujin.
the second link is a link to the dlsite entry. it works fine, but they have some kind of script or something that prevents access when you click on links or something like that. try copy and pasting the url, entering twice in a row, refreshing, etc, and if all else fails just go to the main dlsite page and enter "a-line" and/or this doujin's title (in japanese) into the search form. (make sure you're on the r-18 portal and not the all-ages one.)

as for the link you provided, i think this is a different circle that shares the same name. none of this circle's works seem to be on the doujin db, but if you check the entries for the a-line tag here on the galleries you can see some other entries by the circle.

@returnx: first link doesn't have anything to do with this dojin, second is dead to me, and mugi has no non-Neuro works for a-line: http://shink.me/8kBha Are you sure?

Hey Yui, you look kind of cool.
Also, the art is terrible.
