"Taboo" is an understatement
I've gotta say, I haven't read too many incest themed mangas.
Yuu manages to find himself in all kinds of socially unacceptable
situations with his sister, the neighbor... even his own mother.
Perverted as it is, Super Taboo still manages to pull off a nice
(and at times, dare I say it, sweet) story, as Yuu struggles to
contain his horny inner demons in some very funny scenes. The
characters are developed very well, and have very unique personalities.
By the end, you really care about them, and can almost forgive
them for being such raging perverts. Almost. :)
The artwork is very nice, and the sex scenes are pretty good,
too. While not as explicit as it could have been, very, very little
is left to your imagination. Everything from three-ways to lesbianism
is thrown at you, and it's almost always done in a reasonably
original way. You don't feel like you're looking at the same old
rehashed scenes all the time.
While the idea of mother and son (and daughter and son... and
daughter and mother... and...) going at it may seem a bit too
much, Super Taboo has a great story behind it, and characters
who make it worthwhile. It's definitely worth a read.
