Story: There is no use in dressing this up as anything other than what it is, Boku no Pico is shota porn so if that's what you're into then this one is for you. There's no real story to it, there are a couple of very short scenes to string together the sex scenes but thats about it. If you're looking for something with substance this one is probably not for you & as a yaoi fan you might be happier with something like Sensitive Pornograph as there's more story in there to flesh out the sex scenes.
Art & Sound: There's nothing really wrong with these, it's been animated well so I wouldn't say anything against it on that front.
Character: It's too short to do any development, so the characters are fairly bland. There's no definitive personally traits to them, quite simply it's two little boys who 'experiment' with one another.
Overall enjoyment: Personally speaking, I am not a shota fan. I like yaoi but watching this made me feel dirty on the inside. There are things out there which are more disturbing than this, but because it had no real story to it, it just felt like a flagrant excuse for porn. What I would say is that if you're a yaoi fan who wants to see some simple sex scenes with a little story, then try Sensitive Pornograph instead. If you like younger boys but want something with more story than this has to offer, I'd suggest Enzai which I actually found quite enjoyable to watch.
