Natsuyasumi.

It's a bittersweet story of young shotas in lust. Not as creepy and "group-pissing" as the Pico series but is cute all the same.

To be honest: I wanted to see the trap dressed up as a [maid] and anally plowing the young guy. That's my fetish. But you know...

I have seen many many Yaoi's in my life but all of them seem to have the same story (which is great no hate towards those anime's at all). This one on the other hand was a little different it definitely interested me more than other yaoi's have over all it was just a great anime.

Some of us like porn with plot; some like porn without plot. With porn, especially hentai, plot need not make any real sense, just enough that we can follow. And "Natsuyasumi." hits the mark: boy on summer vacation meets girl, one thing leads to another, girl turns out to be very passable crossdressing boy.
Now, despite the adequacy of the plot, Yuu and Natsuki aren't so well characterized (or perhaps it merely went over my head). They're just two pretty little boys with raging hormones, likely to make otherwise-secure hetero male (and maybe even homo female) viewers question their sexuality. Probably the only significant character detail ... comes to light at the end of the third episode, which perhaps leaves potential for a could-have-been fourth.
Whether or not you liked "Boku no Pico", you may very well enjoy this series.
