It may be a coincidence, but this girl bears a strong resemblance to midorikawa_nao.
I am actually really curious as to who these girls are in this set. After confirming that the girl in post #2615267 was Akemi from Legend of the Overfiend I was wondering if the other leotard girls were from her gymnast team in the movie. Only I don't remember what those girls looked like, haven't seen the movie in nearly twenty years and those girls barely appeared at all from what I remember.
Another possibility is that they are characters from other anime or hentai movies of the 90's, around the same time Overfiend was released. Just dressed up in sexy tight leotards.
