Google has a few tricks to search for material.
If you know your story was listed on a particular website, then you can search just that website. Toss in a couple of keywords and you might hit. For example, say you think it was on asstr.org and there was a Ferrari in the story, a person named Autumn, and she was shave. Then you'd type the following in the search bar.
site:asstr.org Ferrari Autumn shavedYou have to remember to type 'site:' in front of the url.
Maybe you know it was on Kristens Archives. All of those stories can be searched by adding on a bit more to the url. For example:
site:asstr.org/~/Kristen Carl Horse Cowboy nunYou just have to play with keywords. Maybe the author used the word prick a lot. Or pubic hairs. If you loved a story so much you want to find it again, you'll likely be able to come up with words to use to help the search.
If you recall some exact wording you can put that in quotes and it will only give results with the quote material. For example, "fondle her tits" and "strip poker" you would type in the search bar
site:asstr.org "fondle her tits" "strip poker" Try and recall names. That will help a lot.
site:literotica.com Carl Sandy Jim blowjob shavedYou can also search for a particular author. A lot of story sites have authors emails. Or say you found a story you really liked and wanted to read more by that author. Punch in their name or email.
