Matching Maicching Makiko & Machismo.
I am so scamming most of these details from Wiki and elsewhere.
マチコ先生 or Machiko-Sensei, who wears a revealing red mini-skirt, and her regularly finding herself in accidental sexual situations. Machiko is very popular with her students, especially the boys, who take delight in lifting up her skirts and devising traps to catch her in various stages of undress. Rather than get angry, Machiko responds by laughing it off and uttering her trademark phrase,
"まいっちんぐ / Maicchingu!" (roughly meaning "Shame"). Machiko is generally a very kind and patient woman who cares about her students and does her best to help them with their problems.
The manga was created by Takeshi Ebihara, and consists of 8 volumes that were published between 1980 and 1985 in Japan, and serialized in the Gakken magazine Shōnen Challenge. As with the TV anime, the manga series was known for its overt sexual humor. The series was adapted into a 95 episode anime series by Studio Pierrot that aired in Japan on TV Tokyo from October 8, 1981 to October 6, 1983. It was also adapted into four live-action OVAs, and two full-length live-action films.
I've seen the cartoon once or twice in the wee hours on one of the retro-anime channels and I was taken aback by the naughtiness of it all! For example...
The anime series appears on TV Asahi's survey of Japan's 100 favorite animated television series. It was also a frequent target of the Japanese PTA, who campaigned against such raunchy content in an alleged "children's show". I can't for the life of me understand why they'd be concerned!
I'm not sure what a live action OVA is (my guess is TV sitcom-style show) and I haven't viewed it but I have seen both of the movies. Though the prude/rude quotient doesn't really extend much beyond a Carry On movie, there is a paucity of naughty bits shown. Here are the two actresses who have portrayed her, 名波はるか or Haruka Nanami.
and 川村ゆきえ or Sayaka Isoyama. Sorry I can't find her version of the movie, so here's another bit from the above.
Here's an entire animated episode for you, judge for yourself whether it is harmless anime or not.
