I get what you mean. Honestly, the pro, scripted stuff feels a bit dated and boring — the more vivid, immersive stuff is way more my thing. It's called gonzo (basically handheld, POV, amateur, homemade, etc.). CumDdumpVan is kinda mid, though it still counts as gonzo.
Here are some anon cumdumps from X I know.
