If you liked the Kanokon anime, the Anime-Planet community thinks you'd like:
Naeko and Kousuke Fujiwara have just been given a gift from their grandfather: the mess of a mansion they live in will now be cared for by two capable maids – Fubiki, a beauty that appeals to Kousuke’s fetish; and Kogarashi, a huge, strong man who will perform his maid duties to his fullest! What the two don’t know is that they are the last in line for their family’s inheritance, and these two “maids” have been hired to protect them. For Kousuke, this new life is a dream come true; but for Naeko, her mammoth, gravity-defying breasts will never be safe from Kogarashi or any other male’s antics again!
I generally try to avoid same-season recs, but this pair fits so well together I can't resist. Without going into too much detail, let's just say both Kanokon and Kamen have a similar low-brow and excessively ecchi approach to the "story." Breasts are the sole focus of both anime, and I felt equally as suicidal after subjecting myself to a few episodes of each.
Ten years ago, Senpeita Kobayashi fell in love with the girl of his dreams; she left his life, but promised that in ten years she’d see him again and become his bride. Fast forward to the present, and Senpeita is a typical student attending Akebono Academy. That is, until the wide-eyed tiny robot Kemeko crash lands in his bedroom and proclaims herself to be Senpeita’s new bride! As if things aren’t strange enough, Senpeita soon discovers that inside Kemeko is a beautiful girl – a girl who has an uncanny resemblance to his lost love! All Senpeita wants is to be a normal boy, but now he must keep himself out of the way of flying fists, raging jealousies, and battles between Kemeko and Mishina – a global corporation that has a vested and dangerous interest in Senpeita!
Both of these anime's are very much so Ecchi and contain the male protagonist caught between two woman fighting for his affection. In amongst all of this the male leads are trying to focus on school (work or just trying to be normal).
What do you do when you live together with gorgeous twin sisters who are intent on seducing you? This is the daily dilemma that faces Keita Suminoe, and politely declining their offers doesn’t seem to be helping him! Despite his school friends' jealous quips, and parents who think everything is fine as the siblings are not blood-related, this makes no difference to the brow-beaten boy. Unfortunately for Keita, school entrance exams are just around the corner, and scantily-clad girls sneaking into his bedroom at night is starting to affect his chances of graduation. Can he focus his mind in time, or will breasts, panties and milky-white thighs prove to be too much of a distraction?
"Two girls, one guy and lots of Ecchi" basically sums up both these anime titles. The storyline in both is a little weak, but there is plenty of ecchi. If you liked one, you'll surely like the other.
Aoki Daisuke is a fresh, new elementary school teacher, eager to help shape and guide his young students. But he got more than he bargained for with Kokonoe Rin! This saucy third grader has knowledge beyond her years, and a deep-seated mistrust and loathing of adults. She will go to any lengths to protect her friends Kuro and Mimi, including harassment, extortion, threats, and sexual blackmail. And yet, with her friends, she is kind, caring, and self-sacrificing. Can Daisuke gain Rin's trust and save her from her dark side without falling victim to it himself?
Kanokon and Kodomo no Jikan both have light-hearted ecchi strewn thoroughout. Both are hilarious, and have a heavy focus on the corrupted girl seducing the innocent virgin guy. They each also include young or young-appearing characters undergoing acts of perversion and light-hearted seduction while the main guy tries to resist because of his ever-wavering moral fortitude.
Major differences include switches in the age differences between the main male and main female(s); Kanokon has supernatural aspects, while Kodomo is realistic; and in Kanokon, the main male actually has two females vying for his affection, one who is older than him and one who is younger.
Both have fanservice, a plot involving love interests and somewhat timid male characters. This also includes other love interests other than the primary female character for both series.
