are you sure it's just from that one game? do you know of the specific artist? because i have seen plenty of other characters done in this same style a girl in the gym outfit with her panties down pictured from behind is the one that comes to mind
There might be other games by the same artist, but I'm positive this picture is from Sexfriend, at least. The game has a ton of pictures... I think the CG set is over 100 megs.
