"Dave"?

Seriously is this a joke from Desudesu?

If she suffered brain damage and acts like a child, how does she know where "Dave" came from, and how does she suddenly know so much about sex?

Given that they both look white and western, Dave is probably correct. As for the brain damage, you have levels of severity and memory loss when stuff affects the brain, so it's not far-fetched.

One of the very first hentai manga one-shots I discovered. Really cemented my love for MILFs, though I haven't found too many other hentai doujins/mangas that utilize the 'amnesiac' aspect.

@hentailover6983, same here one of the very first H.mangas I read years ago, as for the other thing you mention, for a medium as extensive as Hentai the lack of variety can be tiresome after a while, specially if one is not really into the most mainstream stuff, finding somewhat unique works after being around this sort of smut for more than a decade is difficult sometimes.
