Probably, I haven't read all 214 of this series. However, this few chapters suggest what will happen.

I was looking for a mature series. In fact, a combination of both seinen and ecchi,
I mean a story with a mature topic and some hot scenes. And I didn´t find it here.

The only promising moment of the manga was at thefirst chapter, when the main character finds a mysterious woman who gives him a blowjob and leaves him a small note, which makes him anxious for more. However, the execution is poor, the male character becomes infatuated for her, and although he finds her, everything seems boring. All story can be summarized as the man find many women and have sex with all of them arguing he has a strong "desire", a picture of an orgasm and that's all. Senseless, The art is not likeable either. And the intriguing woman loses her charm trought the story because of her cliche behavior.
