Well this is all I watch so far I think...Remember guys "Fan Service" not Hentai w/ schmex.

Depends on how liberally you want to define fan service. B Gata H Kei doesn't have any nudity whatever, but I usually end up watching some hardcore hentai afterwards... if you're going to turn this into a master list maybe you could divide it into groupings of

Heavy Ero
Moderate Ero
Little/No Nudity but still kinda hot

Using those groupings...
Heavy:
Kanokon
Futari H / Futari Ecchi / Step up Love Story
Kiss x Sis
Queen's Blade
Sekirei

Moderate
Koihime Musou
Ranma 1/2
Strike Witches
Kamen no Maid Guy
Princess Lover

Light:
Ultimate Girls
Asu no Yoichi
Sumomomo Momomo
B Gata H Kei

Just breast exposure.All the titles thats above are animes I watched thats ecchi has breast exposure XD.

Please Teacher (I guess)
Tenjho Tenge (I don't like it though)
Green Green
Shuffle!
Sora no Otoshimono

Aika, Najica Blitz Tactics and Strike Witches have a nice amount.

Edit: You asked for breast exposure, those are all panties galore. Plastic Little has a nice extended bathing scene though!

I kinda have my amount on super ecchi on KissXSis alone that why I'm looking for new animes that show breast :D.
So thanks guys keep them comming XD

I've been watching:

To Love-Ru
Girls Bravo
Kiss x sis

thats pretty much it

Where the fuck is Godannar? The thing was fan service spam all the way through

Agent Aika man, the motherfucking mother of it all (or not, lol)

Chu-Bra, but I have to say I didn't find it at all ecchi because despite 50% of the scenes having flashing or nakedness, I was more intrigued by the underware talk. I wanted to jump into the conversation lol. I think they should show Chuu-Bra to girls in puberty, it would help them a lot lol.

There is one ecchi arc-type of every girl in the show - loli, big breasted, promiscuous, and glasses wearing etc. Check it out.

I already watched chu bra but it was only ecchi in my category.It was all underware.Like I said I like "breast exposure" type of fan service :D.]

Keep them comming boys,I wanna watch them all

Im surprised no one has mentioned Tenchi

Nice lists ^^ i'll try some of your recommendations too.
さようなら。

Midori no Hibi
Chocotto Sister

Nggg~Mayoi is like ToLove all ecchi and no breast :D

Not really. The artist of to-love-ru is also the artist of the Mayoi manga adaptation, however, mayoi is originally a light novel, and the authors mayoi to-love-ru are 2 different people.

On that note, the mayoi manga DOES have some tasty service.
