We get that they are non-blood related siblings and it's relatively acceptable. Their parents allow it and downright endorse it along with their neighbours.
The main character is a socially and sexually maladjusted dimwit, like most Harem Leads, except in this case he seems to have incredibly strange fetishes and having roughly every single negative trope possible. All this while simultaneously denying any sort of relationship between his sisters and himself, while committing sexual acts and having fantasies about them consistently. And they throw themselves at him naked almost hourly. That too.
He also masturbates DAILY while his not-incest twin "sisters" are at each others throats to have sex and marry him. What is the reasoning behind this? He wants it enough to masturbate, but not enough to go to the more-than-willing source that is literally throwing themselves at him anyways.
The fairly consistent ecchi moments are just not enough to keep this absolute trash afloat. I am trying different Anime's that touch the subject of "Incest" to see how they handle it, specifically after I saw OreImo and it decided to handle the subject so poorly and immaturely when it came time to openly show it after a series long foreshadowing and heavy hints. This anime had a promising sounding premise, but then devolved into something that some studio apparently thought was a good idea to make.
What people need to realize is that Ecchi is a sub -style of anime, a sub-genre or even sub-trope if you will that can affect an anime adversely in the audiences eyes. Focusing solely on ecchi is a terrible idea. You can pull off alot of other genre's by themselves like Action, Romance, Mystery, etc. But Ecchi isn't like those. It's a sub-type that enhances or lightens the mood with scenes and sexuality that typically wouldn't be there.
This anime is proof that you simply cannot do Ecchi alone. It's a complete mess that will ultimately desensitize you to the show iteslf(and even Ecchi eliments in other animes as well maybe). Simply because they overuse the same tropes and predictable events through the entire series and the OVAs. The OVAs themselves are a different mess, because they dive face-first into a fully-blown pedophilia relationship with the main character, BOTH ways, and into body-odor fetish and urination fetish? What the hell this main character is such a stereotype... "I'm not a pervert, it's a misunderstanding!" *Licks his sisters sweat off their bodies, making out with them, fondling them, enjoying a girl getting piss on him, fantasies with all of the above + his teachers... What the hell is this?
Would no recommend at all. They started off with a story that could have flown reasonably well, but devolved into fetish-fuel that is the exact reason why people have strong misconceptions about Anime.
