nice movies indeed -though the last scene kinda gave it all away...you can see a censor grid around her private parts which indicates that this flic has been released officially in Japan (the censor grid is required by jp law -and why apply it if you don't plan to make money out of it ?).
...it's probably in the same style as a rather popular "amateur" movie-series in Japan where the women know they're being filmed...just not where the cameras are.
...be that as it may, at least the first two women looked really aroused -something rarely seen in official porn flics
Thanks and I hope you'll post more of this series...
