It's ok, I guess, for a harem with little to no plot. Animation of boobies (and their styling) is quite good. If you're into this kind of stuff you'll probably enjoy it quite a lot. Me... I'm dropping it, since it's not something I'd watch on regular basis: I'm more into actual plot, not the plot shown in the first frames of the 1st episode.
On side note: it's clear that Atena is actually getting super horny, but does not realize that. Otherwise, why would her nose bleed?
