Who's your daddy? If the answer to that question is 'no one :(', you might want to stay tuned for the subreddit I'm about to speak on. See, /r/GayDaddiesPics is, in its own words, 'a place where people post whatever represents 'daddy' to them'. Naturally, this place is very much dominated by gay dudes that like older men. It has over 5,000 subscribers and most of the material is 100% images of daddies in action. Some candid shots, some selfies and some professional porn photographs - all that matters is that there are daddies to enjoy.
In order to give you a rough idea of what the update schedule here is like, you're going to find that the 'new' section is repopulated with new content around 15 times a week. Yeah, it isn't the fastest moving subreddit, but if you want to see more gay daddies on Reddit, why don't you head on over to /r/GayDaddiesPics and submit your own material?
