"Yo Dawg; we know once in a while y'all like some Deep Shit in your H-story, so artist/author dropped some Deep Shit in this here H-Story, so that when y'all see it, y'all can say something like "Whoa, That's Some Deep Shit!" over the Deep Shit in this here H-Story."
Yep - once in a while, we get reminded that Hentai is not always about "T", "A" and "P" .... sometimes there's some Deep Shit to be experienced.
