Trust me, dialogues in JAVs are not worth it (most of the time) just as is not worth listening to western porn dialogues in general.
You are not missing much, and generally they always say the same stuff over and over, "
"sorry for spilling it"
Actually... I cannot remeber any non-JAV movie or scene where a girl, after she spills the cum, says 'I'm sorry.' So, that would be a new thing for me.
I can somewhat agree that a lot of movies are generic and that they repeat the same pattern where girls say how much they love cum - and the boys shout: Ikku! (I'm cumming!)
However; there are some exceptions for this rule. I've came across a ten minute subtitled clip where
Yuri Koizumi plays a schoolgirl who reads an essay (in all male classroom, of course) how much she loves cum. Some quotes:
'Cum is more important to girls than man realise.'
'The moment I swallow the cum down, I feel like I've become the one with the men who shot their loads for me.'
'I feel that facials directly express men's feelings.'
'I'd suck ANY cock - as long it shoots cum for ME!'
etc.
It is an older production and I'm not sure if there exists the whole film.
In the clip there is a caption that says 'Yuri Koizumi' from
SCC-10 so maybe someon can identify which movie it is?
And all girls should have that training and attitude!
