You are welcome, i found this research usefull also! I believe that Astarotte is number one because it takes place in a world where ecchi behavior is normal.I recomend you read the manga and see the anime also, it has "that" feeling you found in Strike Witches.
Kodomo No Jikan is great both as a manga and as an anime, i recomend both.For Kanokon and KissXSis i think you can stick to the anime and read the manga only if you like the anime.In Queen's Blade they power their weapons thru masturbation so there is a lot of that and there is an OVA where the elven master instructor exposes herself all the time. I've mentioned the Pokemon episode because of its historical value and because of its deleted scene where James literarly turns into a woman and shows his breasts to Misty.

There is a Touhou anime! You can watch it on youtube, but i think its a bit abridged, and on torrent sites like nyaa.se Its great and has a lot of casual nudity and implied yuri.
The story of 15 girls is funny, i didn't bother with the plot but the characters are put in situations like, "they are late, lets have sex!" :) has incest, lolicon and a lot of stuff. Imouto Jiru its a little gem in my opinion with a legendary scene where a neko girl wearing only an apron is cooking while wiggling her round ass, too bad the series was left unfinished.

More sugestions are: Another lady innocent, yet another unfinished masterpiece that is floating around in uncesored form. An example here, the daughter comes home walks in on father who is having sex with a maid, hugs him, kisses him and he ejaculates in the maid.Maids walk around with their tits out and so on.It also had a good plot, sadly it was also never finished!

There are a lot of similaries with strike witches to be found in the dark world of the '80 anime, in series like Cream Lemon and Lolita anime if you want to go there.Many of those are obscure and hard to find! Good luck!
