Boobalicious
Boobalicious, originally called Milk Junkies when it was a hentai game is a decent, though short, movie. The animation is decent, the plot is above-par in at least delivery as compared to other porn, and the action isn't extreme but not bad, either.

The movie starts of on the beach, a guy named Wataru and a blonde girl named Rena are having fun, but they're being spied on by two busty Japanese women (you can't tell since all anime characters look essentially the same race, but it comes up at some point). Apparently Wataru has lost his memories and this is a very bad thing. They notice quite abruptly that Rena has no chest, which somehow means that Wataru has amnesia (I didn't write or translate the thing, you should probably just go ahead and watch it for the action).  They vow to seduce him with their megatits, but they're not going to get on that (no pun intended) until tomorrow, right now they're at a California beach and therefore must run around with their tits hanging out. Ok, I'll admit, the entire thing makes about as much sense as a penguin in a sundress, but that's more than the average porn (animated or otherwise) is going to give you, and besides you're not actually watching this for the plot, now are you? So if you want something to laugh at, fap to, or both, this will probably do it for you, but if you prefer a better storyline and don't mind the more intense stuff, I've heard that Urotsukidoji / Legend of the Overfiend is one of the best, albeit monster-themed, hentai movies around.
