What porn have you lost and are now searching for? What's your white whale?
Mine was this image
I liked the aesthetics of it and added it to the room I had in EmuVR as a poster. Unfortunately I lost it when a drive died. I had tried searching online for it but searching for lewd cyberpunk wallpapers wasn't working. I finally stumbled across it in a lewd wallpaper thread the other week.
Waifish, extremely pale girl is getting absolutely railed in the ass, going so hard that her neck is pushed against the ground at what must be a very uncomfortable angle. He then pulls out and shows the gape.
I've been able to find bits and pieces but not the full version I watched first. I'd love to know who the actress is and see if she's done any other similar work.
