[Update 02/21/2021: need to redo this entire review and fix the screenshots.]
At a company mixer a guy meets an attractive young woman. They start seeing each other and six months later they get married and she moves in with his family...then the truth comes out: she's a raging nymphomaniac who cannot be satisfied. He tries and tries until finally he becomes impotent from the stress of all the nonstop fucking. He starts spending more hours at work and in her sexual frustration she seduces the entire family! Now his dad, the sister and grandpa have all become sex maniacs who want to do nothing more all day than stay at home and fuck his wife!
The running time for this little gem is only an hour, but it is packed to the gills with sex, nudity, insanity and funny moments. I think the thing I like most about this movie, besides the humor, is the sex scenes are actually sexy! Yea, the idea of a woman seducing an entire family is perverse, especially when they're gang-banging, but from a clearly physical standpoint the sex scenes were fucking hot with interesting positions and spirited performances. This movie looks like it was a lot of fun to film. Also, it never delved into the lower depth's like Miike's VISITOR Q or Pasolini's TEOREMA (although the grandpa jizz scene was pretty disturbing), instead it just stayed light-hearted the entire movie.
I don't know much about the director Yutaka Ikejima, but I was very impressed with this outing.
