A Sex Stories is a hub of erotic text that has a gay section devoted to the world of cock and bum fun. While the site hasn't been updated in over a year, there are still a number of stories for you to go back through if you like tales of gay indulgence. Titles ranged in theme from martial arts trainers and students fucking down to mutual masturbation between groups of interested high school studs. ASexStories.com does have a review section for users to write what they think of the stories too, so if you value the opinion of other enthusiasts of gay erotica, be sure to check those out.
Out of the erotic stories sites I've reviewed here on My Gay Sites, I'd say that this one likely has the least optimal design. Each archive page lists just 10 stories with 119 archive pages taking you back through to the content that started to be submitted way back in October of 2001. The lack of tags also makes navigation through the gay stories here a little cumbersome.
