So yaoi hentai=gay incest porn

Isn't Boku no pico with young kids? (at least I'm pretty sure, I haven't seen it) two little boys and then an adult. Yaoi just means gay and hentai is any form of Japanese animated porn

So he pretended to shield him from someone's "trap" by letting him fall in a trap of his own.

Pretty much, he pretended to save him from the trap by just letting him fall into the trap

But the first "trap" wasn't a trap at all

No, it’s a very good, regular anime

Oh wait, I mean yes

Well it ain't all incestuous, the adult is a client at Pico's grandpa's hotel, there's also Pico's friend and a third kid.
If you're wondering, "boku no..." means my, which is the only word these two animes have in common.
