Gave it a try.
I guess this is not ecchi anymore but can't be classified as Hentaï?
There are problems with incest and underage too...

Other than that, except for the 3some, fingering, accidental cunni and Riko's five helping hand, that show didn't really appeal to me.

I guess everyone has their limits and plays around them that bring them to laugh hard, or just remain stuck depending on which side the gags are...

For example I just watched Ichigo 100% and as low quality as it was, its value was in the Oumi academy raid that just had me laugh hard almost the whole ep, when there wasn't anything so special about (but the build up in the other eps and that particular one was great)

I will probably watch it till the end, hoping for an ep to use some kind of build up and have me laugh out loud.
