Non of these are hentais
Green Green - Girls transferring to a remote all-boys-school...
Girls Bravo - One side-character always tries to get the girls naked (even his fantasies are visualized
)
Kanokon - Main giant breasted girls wants to [censored] her looks-like-a-little-boy (with a woman's voice nonetheless).
Kissxsis - borderline hentai, two sisters want to bone their non-blood-related brother
Sora no Otoshimono - this one mixes serious plot and fanservice comedy very well (one episode the main character turn into a girl to "explore" the girls public bath, he gets too aroused he start to shoot lasers).
He is My Master - Maids, costume [censored] and one horny alligator.
Kamen no Maid Guy - this is a case of an awesome character in a wrong show (every episode name has something with boobs in it)
Strike Witches - all the girls in this show don't have pants...
Let me repeat myself and add some more:
Asobi ni Ikuyo ("Let's Play) - An alien cat-girl comes to earth to "play" (with GIANT breast), he has a childhood friend (with GIANT breast) and another girl from his club (with FLAT-AS-A-BOARD breast) and shenanigans ensue, there are also plenty of cat-girls with variable breast sizes (ranging from big to HOLY CRAP THOSE ARE HUGE ), there is a plot if your brains is still paying attention.
Panty & Stocking with Garterbelt - its like the PowerPuff Girls on Acid, crazy and perverted (with the latest episode featuring a shortage of tissues so males across the city couldn't masterbate), very hilarious.
Amaenaide yo! - a guy who lives in a shrine with several other girls, he gets supper strong if he sees a girls naked, nuff said.
Moetan - A parody Magical (little)girls series that also teaches you english !
Princess Lover! - based on a porn game has plenty of nudity (especially episode 6) and also has a hentai OVA (but with different voice actresses).
Oruchuban Ebichu - Perverted hamster...
Seikon no Qwaser - People get powers from breast milk, yum.
