From which JAV movies are these clips in this clips4sale site from?

[Magnusmaster]

I found a clips4sale site here with a LOT of clips from what appear to be JAV movies (because I doubt so many people have bought such overpriced clips). Does anyone know from which JAV series or maker are these clips from? Thanks.

would be interested to know if anyone has any more info on this. I am sure these clips must be from some movie series but it is difficult to find anything on r18. The clips feature some of my favourite actresses like elly akira, Aika and Reiko Kobayakawa. The below websites seem linked in some way:

Anyone know the movie IDs for this series or are these videos all original content not available on r18?
