The pure and innocent Nanako Matsutaka is a seemingly normal girl with a normal student life, except that she’s enrolled in a Pervert Physiology Course run by the depraved Professor Meshiya! Being a naïve girl with no sexual experience and a disdain for anything perverted, Nanako is at the bottom of her class. As she attempts to avoid flunking out of the course, Nanako works alongside her classmates – the calm and collected Konogi, perv extraordinaire Mizukoshi, porn enthusiast Michikawa, and the co-dependant couple Taguchi and Makiko – in order to complete her various “assignments” from Professor Meshiya.
Comedy OVAs with load of sexual innuendo involving innocent girls and their heavily perverted peers. If you are looking for something involving sex jokes with actual sex related acts (YES, THERE IS VISUAL DEPICTION OF SEXUAL INTERCOURSE) instead of it being just on the verbal side of things.
Both OVAs are taking ecchi to the extreme. Both take it to where its just wrong and a waste of time. STRONG SEXUAL CONTENT! This is basically hentai. So if you enjoyed one, i dont see why you would not like the other.
Hen Zemi is, by all means, a better version of Koe de Oshigoto. Hen Zemi is actually funny, instead of just making you feel like a perverted old man.
I wouldn't recommend both ways, but definitely if you liked Koe de Oshigoto, Hen Zemi'll feel like an upgrade.
Fifteen-year-old Yamada has just entered high school and is gung ho about achieving her ultimate goal: to have one hundred sex partners! There’s just one problem: she’s a virgin, and she hasn’t even had a boyfriend! To get the ball rolling, Yamada decides to target a shy boy named Takashi from her school; but even though he is also a virgin and she ruthlessly aggressive with her feminine ways, it’s not as easy as Yamada hopes. Though they begin to have feelings for each other, will Yamada and Takashi ever get past first base?
Both of these series walk that line of being so close to hentai, but it's own plot prevents it from devolving into just just high school sex.
The comedy is adult and sexual based, but they both come at it from opposite sides: Yamada thinking about nothing but sex and then getting involved in it is different than what she thought, while Kanna hadn't really thought about sex at all only to be suprised at it being not what she expected.
Both hillarious stories about teenage high school girls learning about sex in not so ordinary ways.
Makoto and Yura Onoda are a newly married couple. Luckily for them, even though their marriage was arranged, they are deeply in love. However, even though they are both 25, neither of them have any ‘intimate’ experience, and consequently, they are equally as unsure and clumsy. With a little advice from Yura's friends and sister, this newly-wed couple will eventually get it right and explore the hardships of marriage, and the wonderful world of sex, even in daring places and awkward situations.
These are partly the same. In both the female charictors are just learning about sex from friends and family but in Koe de oshigoto she learns about it to become a good hentai porn voice actress
Puberty is an embarrassing, trying time for a child. Your body changes, you start to have feelings for the opposite sex, and more than anything, you are confused and bewildered about what’s happening to you. Tsubomi, Rea, Saya and a group of other fifth-grade students are being faced with this difficult event, and will experience the joys and horrors of it together. From learning about the difference between the male and female bodies, to experiencing a first kiss, to discovering the cause of pregnancy and even getting a first period, Tsubomi and her friends will finally learn what it means to be a grown up.
They are both about an innocent schoolgirl learning about sexuality-related things, though Tsubomi is a 5th grader and Kanna is in her first year of high school. Both shows also have a mix of comedy and seriousness.
Be advised that Koe de Oshigoto is a lot more adult than Naisho no Tsubomi.
Both series are also quite short: Naisho no Tsubomi is three episodes long, while Koe de Oshigoto only has two.
