If you don't know who Sean Reid Scott is, can you really call yourself a muscle-literature fan? He is a fantastic author who writes some of the best, realistic muscle worshipping stories you'll find. You may have read some of his stories in the past without knowing it, as he has worked under a few different aliases, such as Derek Flex and another one he has used on Amazon that I can't look up because my computer is email is currently being stupid.
Most of his stories involved a closeted man meeting the huge bodybuilder hunk of his dreams (and ours). His stories are lighthearted, often romantic, sexy, and full of hyper descriptive muscle admiration.
It was hard for me to choose one to post, so I started with this one: Camo Hat.
Be sure to check all his stuff though. He even has several books published on Amazon.
