This anime goes from one hentai-scene to another. It's story content is almost null. The anime is that you force the lady that hit your father's car to sign a money loan paper. With that, you have fun with her and her two daughters which happens to be in your school. Oh, your father and his secretary are in the fun somewhere too.
The bad endings are you getting arrested. The only good ending is your father getting arrested and you live happily, which I didn't bother to get.
