Overflow is about the relationship between a man and his 2 female friends. It is hentai.
The plot is nothing special, typical hentai. Basically the female characters get caught in enticing positions. The dialogue is good and crisp. The episodes are quite short so the whole series is like 40 minutes. The characters are decent, basic ecchi characters. The main characters are the only ones that matter. There are characters in the background, but they are for the background m
The animation is good, for a hentai. I really liked it. The voice acting is good as well.
I would recommend this anime to someone interested in Hentai.
