A user here made the perfect porn site awhile back:

infiniporn.net

Basically, you can doom-scroll a variety of 20-second long porn gifs infinitely. No bs, just thousands of GIFs that load quick.

I prefer to download instead of stream or watch a bunch of gifs, so when the time comes I just hit up a zero-day rip site and browse all the scenes from a majority of the major network sites.

Most reliable, extensive, and easy to use is 0xxx.ws

These days, bing video honestly.

Used to be asstr, these days I have to make do with literotica and storiesonline. 😞

Hard picks these days, I still miss PureTNA, but RedGifs is probably the most consistent hit.

My current favourite sites are:

pmvhaven.com

femdom-joi.com

redgifs.com

Elite babes to find a model, then search stash db for scenes, torrent sites for the file

Tubegalore, I like it because it searches a bunch of sites

Xvideos. As far as traditional free porn video sites go, it's the best I think.

I'd have to say http://Feisty.XXX

pornzog has good results on certain topics. You need to dig sometimes, though.

Spankbang.com

Tube Safari and purecfnm

I use neporn.com and fpo.xxx a lot these days.
