I just looked at that video magnified, it was not vintage. She looked the video from some porn site, it was apparently two men and a woman. One of the men tied her hands behind, while she took blow job from another. Dasha would fast forward to the point where the woman had gagged and one of the men rubbed her breasts. Then there was something that I certainly didn't understand, might be rubbing, dildoing , but anyway the man had a pantyhose on his head. Dasha could also change the video twice in between. In the final scene, the woman was tied to the bed and there were also two other persons, one at least was a woman who apparently fisting that tied woman. The display had also a smaller video screen, with the exception of the last video.
On the basis of that video I think she is quite pleased with how the Demid treats her during sex.
