If you liked the Kanokon anime, the Anime-Planet community thinks you'd like:
It's time for the Sexy Appeal Battle, and many of the Ladies Versus Butlers cast are ready for some skin-baring, breast jiggling action. Sanae, Kaoru, Ayse, Hedyeh, Pina and the other girls bear their backsides, press their mammaries against glass (and each other), lay provocatively across tables and raise the ecchi bar to the max in hopes of winning each battle, a boisterous crowd cheering them on in the background.
On its way to Kure Port, the Amanohara stops at an island to be repaired, giving some much needed rest and relaxation for Shintaro and the Raimu unit. The backdrop of a gorgeous festival is the perfect diversion for Momen, Asa and the rest of the girls; they use their womanly assets to their advantage time and time again in an attempt to finally get to their beloved teacher. But amidst the shared baths and nudity galore, trouble is brewing... for a sinister figure from the gang's past is soon to attack and disrupt their newfound vacation.
In another reality protected by a sentient portal lies the Magician's Academy – a facility for learning about the magical arts and the power of summoning. Takuto Hasegawa is one such student who must balance his life on Earth with his life at the Academy. His life was relatively normal until one day, he summoned a naked creature who he dubs Tanarotte, and who subsequently becomes his servant. Takuto must now care for this busty beauty, but it won't be easy – representatives of both the god and demon realms want to put a stop to Tanarotte's existence, for once she chooses to become a god or demon she will throw off the balance of power between the two kingdoms. Now, Takuto finds himself in the middle of a variety of ecchi and cleavage-heavy situations as he tries to continue his studies, while slowly and inadvertently acquiring more scantily-clad women that he must watch over.
Kanokon and Macademi Wasshoi constantly push the boundaries of ecchi and softcore porn, to some extent. If you like uber ecchi and tons of nudity and panty shots, either of these titles will be good for you.
The anime and cosplay-loving Sakura Nankyoku – known by her peers as Penguin at her old school – has just moved to a new location. After suddenly becoming student council president, she finds herself in the middle of many bizarre and ecchi situations. Panties fly, transformations are plentiful and the day is never dull in the life of Sakura, her third-grade sister Kaede, her tomboy rival Kujira, Cha Chi from China (who wants nothing more than to be Kujira's "boyfriend"), and more!
Kanokon and Penguin Musume Heart are both extremely ecchi anime with little to no substance to speak of. If you like nothing more than panty shots and random nonsense, knock yourself out with these titles.
Kei Kusanagi is a shy teenage boy with no romantic experience whatsoever... until he finds out that his hot new teacher is actually an alien! In order to conceal her identity, the two are forced into a pretend marriage... but is it really a pretense, or are they actually falling in love?
Well, they have a lot of similar parts. Both main female characters fall inlove fecause the main male character promises to keep their secret (revealing of which will cause the main female character's moving to another place). The second reason because of which i recomend this anime is because in both of them the mother of the main female character tries ti help the main female character to improove the relationship with the main male character, by acting liek she is seducing him and with the help of someone under her command (in Onegai Teacher the little sister, and in Kanokon the Ice lady). Also in both of them the main characters have recently switched to a new school, which means they make a new start in life. Another reason why i recomend this anime is because in both animes, the main character's classmates appear out of nowhere while the main characters are alone and trying to improove their relationship. The difference is that Onegai Teacher has less nudity and ecchi moments, but it has more developed romance part.
