This hentai makes Boku no Pico a good anime in comparasion.
The story (I didn't played the game, so I don't know if it's the same shit or way better) is horrible. It's about girls going bananas after been raped by a guy (one of them kills herself). And the ending is nonsensical.
The art and animation were made without any effort. It's so poorly drawn and stiff.
For some reason, the sex scenes features moviments that sounds like a crêpe paper been kneaded. The dialogs are very lame and pointless.
The characters are boring and forgetful.
I didn't find any enjoyment of it. For its not convincing sex scenes to terrible animation.
Overall, avoid this at any cost.
