Oh man, how much I love the idea of a nice cum slut: a dude that just wants your seed so bad that they're willing to do whatever it takes in order to get it. Okay, I'll stop with the fantasy right now because I think it's time I introduced my readers to the great subreddit known as /r/GayCumSluts. The name says it all, but I think you have to check this place out to see what's really on offer here.
There are currently just shy of 9,000 readers, which is a little on the skinny side, but being a community for three years means that there's plenty of content in the archive for you to be taking a look at. I should note that the best way to enjoy this subreddit involves heading on over to the 'top rated' area and sorting by 'all time'. That way, you'll see literally the best ever posts that have graced the gay cum slut lovers.
New material usually comes in around three times a day, so it doesn't update all that often. It has a good moderation team and doesn't take any shit. So yeah, head on over and go crazy if you're down for some gay cum slut fun.
