ULMF Everybody’s familiar with vanilla porn. You know, the standard stuff: missionary, blowjobs, hardcore anal fisting. Most porn fans have a general awareness of hentai, but few have any idea how deep the fandom goes. Newbies to the world of cartoon titties and pixel-game twats can get lost easily. What the hell do you do the first time you find a site like ULMF.org? The site gets a couple million visitors a month but is utterly baffling to a newcomer. ULMF stands for Unofficial LineMarvel Forum, which either makes sense immediately or means absolutely nothing to you. There’s no in-between. You probably found this review trying to figure out what it’s all about, or else you’re one of LineMarvel’s apparently rabid fans, Googling his name in search of another bit of pornographic Flash gold.
