Ane Jiyoku Tsukushi: Neesan no Shitagi

I know this is a hentai and it isn't very story driven but this was absolutely stupid is so many ways. So it's incest which is already crazy (not here to kink shame) but the way it goes about happening is just mind bogglingly idiotic. So the Male Lead has a girlfriend that he's in love with and just started fooling around with but hasn't had s*x with her yet, and his older sister is the council president and the school idol so she gets lots of confessions so she decided to have a classmate act as her boyfriend but is secretly in love with ... her brother (assumed not 100%) and wants them to have their first time together. So before her brother can have lose his virginity she has her fake boyfriend go after the Male leads girlfriend then pretty much leads her brother so he can see it happen with his own eyes. I won't get go too much in on the girlfriend because she is all kinds of f*cked up too, for instance she really didn't put much effort into fighting the guy off and as soon as he makes her climax, she basically fawns all over him and says she wants to give him more of her firsts Eve though she said the same thing to her boyfriend when they had their first kiss and he went down on her lol. The older sister comforts her brother later that night even though she caused all the damage and sleeps with him but says it's only for tonight. She ruined her brothers relationship and doesn't even confess to him herself and just tells him to her a new girlfriend (yea get another girlfriend so she can mentally and emotionally scar him some more).Then by the end the Male lead finds out what actually happened and is rightfully angry so he decides to blackmail his sister into becoming his slave and the sister never gets to confess why she did it. I came across this and it didn't have an NTR or Incest tag so I checked it out and I was pretty surprised at how stupid the story was. With story this bad, they should have just skipped it all together and just did the s*x scenes with no story or context lol. This is the first review I'm doing on a hentai because I just couldn't keep my mouth shut. Utter stupidity. The only positive is that he got some modicum of revenge but it ends before anything is confirmed.
