First I need to say a disclaimer, I was unable to find this anime with English subtitles, so I have used my limited Japanese ability and guess work (90% the latter) to piece together as much as I can about the story. If in the future I find a version with English subtitles, or when my Japanese has improved I will be sure to re-watch and make corrections to this review.
The plot of this comedic hentai movie revolves around a kind hearted and mild mannered salary man with an incredibly large penis, which is anthropomorphised as an incredibly horny gopher.
The salary man accidentally
walks in on a western adult video shoot and the actress is amazed at his size, although he tries to remain professional the cast and crew of the porn shoot are all amazed at his size and try to persuade him to star in their movies.
The rest of the movie is him accidentally shocking women with his size and them instantly being captivated and determined to have sex with him, these scenes play out without much drama and include 2 western women, 1 geisha style woman and a fat yakuza boss, full marks for variety.
The remained of the movie is a lot of boardroom scenes, though I was not sure what the plot was.
The animations were fairly basic but the art style has a dated charm and the lead character seemed likable enough. The sex scenes lacked variety in setting and action but at least had a wide variety of female characters, as well as one of the few examples of dog action I have ever seen in an anime.
Overall I would not recommend this anime unless you have a thing for fat Yakuza lady sex.
