I haven't lurked around this section before, so forgive me if manga isn't appreciated, I'm but a mere noob.
So I stumbled graciously onto this little ditty of a comic called Sekirei. It's hilarious in that it's completely typical of the Japanese animators to do.
Seriously.
A quick synopsis. Our hero is a loner guy with no real friends who was kicked out of his home to go to college. After failing the entrance exam for the second time, due to mere nervousness, all seems bleak. Until, WHASSAT?? A huge-breasted beautiful woman falls out of the sky! And two others are after her. She runs away with our hero, and the two exchange a kiss. And wings explode from her back. Bear with me, bear with me. It's revealed that she is a sekirei, a race of mostly-women, all of which seem to have HUMONGOUS boobs, who are sent to wander around Tokyo to find their master-friend-husband guy so that they can fight eachother to the death. Last one standing gets to do... something, I dunno, I wasn't paying attention due to the GOODYEAR BLIMPS EMERGING FROM HER RIB CAGE.
Yeah, so this chick is completely devoid of social etiquette, so for the first issue of this series, she's topless quite a lot. One, from her bathing or changing or sleeping in the nude, much to his surprise/delight/deprise/surlight. Two, from battles with other sekirei, as her clothes are always ripped off in those battles.
It's got a vein of bishonen, a gallon of hentai, ecchi, and h-anime, and a dash of a pretty decent plot (I guess).
Avert your eyes, children.
