Despite its almost two decades of existence, Sexfriend is a very enjoyable hentai with schoolgirls, teachers, threesomes and even some romantic development. Probably from a time the term Sexfriend was being popularized.
Animation wise it shows its age yet it is still better than half of the hentai out there that gets released these days, it is uncensored, it has pubic hair and an easy to follow story.
On the other hand, Ami Shizuki voices Hayase Mina, that alone is a plus. It also has a game that explores the characters in a more deep view besides sex but it is in Japanese and might or might not run on your computer.
