Well, it's quite doubtful. First of all, the term 'orgasm stories' is rather personal and private in nature. While there might be some personal accounts shared in certain communities or literature, having a set of 1800 for free seems far - fetched. Also, sharing such stories without proper consent might raise ethical issues. So, I don't think there are truly 1800 free orgasm stories just floating around.
In general, the idea of 1800 free orgasm stories is suspect. There are many websites and platforms that claim to offer all sorts of content, but often they are either not reliable or violate some form of ethics or legality. When it comes to stories about such a personal and private topic, it's hard to imagine there being a large, free collection of exactly 1800. It could be a marketing ploy or just a made - up number. There may be some scattered stories here and there, but not likely a neatly packaged 1800 of them for free.
