Literotica Review

Literotica has been publishing sex stories since 1998, and with roughly 900,000 stories in English alone, it is the largest library of erotic fiction online.

Everything is free. Readers write the stories, readers rate them, and the community runs contests through the year, from Summer Lovin’ to the annual Halloween contest. There is audio erotica as well, a podcast, poetry, a forum and a newer interactive platform where you decide how the story goes.

The size cuts both ways. Quality varies a lot, and some categories go far beyond what I would ever recommend here, so search by tags and stick to the highest-rated stories. Smaller collections exist in Spanish, German and other languages too, and the writing community is famously welcoming to first-time authors.
