There's loads of them and the titles do not list the names of the participants, so you only know who's in a session if you get to see a screenshot (and most of the compilations on here only include a small handful of screenshots from the full collection).

This is Darren (from some other videos): https://www.gaytor.rent/details.php?id=433731457ec4fa5ec7a07f35b34fa0519400042e0a72b979

So far I have seen him in:

BrutalTops - Session 1
BrutalTops - Session 10
BrutalTops - Session 42
BrutalTops - Session 169

But there is at least one other that I have seen an image from that I have been unable to locate (and there may be several more).

Appreciate any help.
