With just under 5,000 subscribers, /r/Jacking is a subreddit that states it point from the get go: 'you were going to do it anyway, might as well film it'. So yeah, if you haven't clocked in yet, Jacking is a subreddit where guys from the site record themselves jerking themselves off and then share it with the community. Note that this isn't supposed to be a place solely for gay guys, but there are still plenty of scenes where people identify as being more interested in asses than pussies.
To give you a little bit of an idea on how regularly new content comes in, the last 24 hours have seen 7 new clips uploaded. That's pretty damn good if you ask me, and if it can keep up with that rate, I can see /r/Jacking growing quicker than my dick after spending a few minutes sampling the goods it has to offer.
