It was linked from https://web.archive.org/web/20200813163926/https://twinkcity.com/tag/aggressive-wank/ but I never thought to download it when the site was around. I've been able to figure out that the video was hosted on twinkybf.com, but both sites now just redirect to Chaturbate. Wayback Machine archived a bunch of their content, but this was not one of them.
