Just a small yet important update, at least for me since it's kind of a "realization moment"
So, I was reviewing Japanese vocab today and it dawned on me that 合格 (usually translated as "passing an exam") is actually made up of "meeting" and "standard". So, in other words, "qualifying". And then I remembered all these JAV movies with a similar plot (
one of which is among the best for me in all of the JAV in general and which made me cum back to it time and time again...): "
mother disqualification"
So, yeah, the premise is that the mother does something so un-motherlike that she cannot be called a mother anymore. And actually, there are two ways it usually goes: either the mom gets f...ed by her son's friends or bullies — or she f...s her daughter's boyfriend. I like both actually
Another interesting thing is that there are actually a lot of good series for this*... Well, at least two that I've checked and one more that I remember seeing the covers for. And last but not least,
Kaho actually starred in two of these! So, one by one (on examples)...
DVDES-910 — The Holy Grail
Mother f...s her son's classmates, basically, and gets knocked up by one of them
I won't get tired of saying how gorgeously meaty Kaho's tits look here. A time-tested cum-backer for me
This series has 4 movies, and all the "moms" are at least a bitt endowed in the bust area, by the way
WANZ-512 — The Forgotten One
Mother f...s her daughter's (boy)friend and has a child with him
Because I actually forgot that there is a title with Kaho that's so close in some ways to the one above
5+ titles, with other "moms" in the series being AIKA and Sasaki Aki! I'll be (re)watching all three, or maybe all of the series, very soon...
URE-019 — The Adaptation One
Don't really know anything about this one plot-wise, but it seems that the mother is doing some shady illegal sexual stuff, and her daughter is somehow involved or gets hurt by it
Anyway, it stars Reiko Sawamura, which's always a plus, so, might be worth checking out
Basically, it's also a case of "cum-backer keyword", i.e. when a keyword pointing to a premise is so strong that when you remember it, you just can't help checking what titles have been made using it...
Also, these are not all that have this kind of a premise, i.e. there is
UGUG-063, and its cover alone is... something

失格 seems to be a good keyword for this kind of thing if you combine it with 母親、ママ etc.: MDVHJ-071, NHDTA-700...
* None of them actually uses 不合格;; they use 失格 (which can be just seen as another way to say "disqualificaiton", though) and 辞め (quitting); still, it's the rhought (that led me to remembering about this) that counts
