Katei Kyoushi Ga Ochiru Made [English, 191 pictures], by Hoshino Ryuichi
That specific combination isn’t unusual, we’re with
– EXCELLENT sex, drawn with skill, low censorship (minuscule semi-transparent rectangles), intense (vaginal, anal, paizuri, double penetration)
– A scenario made of a succession of red flags. It’s not specifically drama or an unholy abomination, but I got terrible facepalm urges from this non-stop red flags succession.
How to say… Imagine a woman revealing, during her wedding night, that’s she’s still a virgin (talk of a sheltered princess living in the 1800s). Imagine her husband being fired but still going to work to prepare his successor. Imagine the wife becoming the private tutor of a young adult with suicidal tendancies who’ll off himself if she doesn’t undress…
And it’s only the first third of the volume, for a main story arc that covers the whole volume, save its final chapter!
Again, if you want easy faps and won’t read the speech bubbles, you’re with masturbation gold. But if the story matters for you, and you’re the vanilla lover like me, AKA you’re not too hot for humiliation-based hentai, I recommend you skip this one. Your call (And, again, it’s got 191 pages of excellent fap materials!)
Release credits are for SL-Gundam and Biribiri, many thanks for the end of year treats!

At first I saw a lot of missionary; more missionary than a BYU summer camp.
Then gradually the sex got better, but the story I was ignoring, started getting on my nerves.
Anyhow, good sex; but I really ain’t interested in what was going on in that mess of a plot.
