Removing home sex of a young couple in black and white retro format without sound

Video entering the network from a private collection. It presents the shooting of home sex of an unknown young couple. Moreover, in a kind of black and white retro version, which to some extent gives the video additional piquancy. At least even in the sense that we do not know whether it is modern or dates back to the time of the youth of our grandmothers. It is a pity, besides, that there is no sound. And then, according to its quality, it would be quite possible to build some assumptions on this account.
