Holy moly. I just myself rediscovered these stories by going back in time on my list. Author Bobaroo2 on Nifty Gay Male Stories website wrote some fantastic muscle-centric lit way back in the late 1990's. He clearly knows his stuff about muscle and bodybuilding from his descriptions and writing.
His stories involve my favorite male subjects, middle-aged muscle studs. The gents in his stories tend to be blue collar dream studs in their mid-30s or so. Maybe it's only because I'm about that age as well now, but that to me is the prime age for muscle hunkiness. Mature enough to have years and years of growth and experience, but still young enough to have full stamina and that smooth, taught, look to the muscles and body. There's a reason why most Mr. Olympias are in their 30s! If you ask me there aren't nearly enough stories about guys in this age-range (wink wink nudge nudge to all the authors out there ).
Because I'm smitten enough by these stories and they are relatively short, I'll share two. The first is about two guys who meet a tall, studly fella at a new bar catering to bodybuilders.
The second is nice little story about a super huge, super strong landscaper.
The type of guy I picture Bobaroo2's stories:
