This is basically blueball the manga. Sex scenes never go anywhere and the more reasons this author comes up with the worse it gets each time. Her friend takes her to get some but "changes her mind" out of no where? Right. And I guess she will "eventually" get it with the token "cool guy" who wants to protect her for no reason. Erotic premise and concept that is anticlimactic, stereotypical, and never goes anywhere. More interested in seeing whats going down with her sister which is cut out. Dropped.
