If you're looking for anime similar to Nana to Kaoru, you might like these titles.
Asuka, Mai, Nana, Riona and Yuki have sexy secrets that they'd like to share. Mai explains the lines and curvatures of the legs when a woman crouches down. Nana works as a maid but believes someone is watching her. Riona becomes excited when she wears the color red, and demonstrates different ways a woman can sit. Yuki wears skimpy outfits for her lover. And finally, Asuka is frequently kept after at the hospital to take part in a sexy roleplay with a female doctor.

If you're looking for a mindless, short OVA that exists solely for fanservice (and is quite adult, nonetheless), these two are a good fit.
If you enjoyed watching G-Taste or Nana to Kaoru for the ecchi fanservice (bordering on hentai) you'll probably enjoy the other.
Both of these anime are about horny and kinky girl(s). They're very different types of anime, but they're about the same thing. G-Taste is more informative and Nana to Kaoru is more just hentai.

Two short & mindless OVAs about sexual deviations. I didn't like either of them, but if you enjoyed the one, you should also check the other.
Two mediocre OVAs from great manga about relationships as seen through sexual deviance. Both leave all the strength and depth of the manga for cheap ecchi thrills. If that's what you're looking for, these do alright.
it is sexy

Both shows have fetish/BDSM as their main theme and similarly revolve around female MCs who have secret kinks that they hide from other people. Gushing has more comedy in it and a more sophisticated story, whereas Nana To Kaoru is a simple 1ep OVA.

Both of these shows are heavy on fanservice and involve two classmates having...extracurricular activities. Both include some aspect of S&M play, although Rescue Me is more theory than practice. Still, if you thought one was fantastic, try the other.
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.

Both are about people who like doing perverted stuff. In Hen Zemi the main character doesn't like doing perverted stuff a lot though. Both anime have other characters forcing the main girl to do perverted stuff, but in Nana to Kaoru the girl actually likes the stuff.
