Pornography = boring.
This thread has been dead for a while, but one of my favs. Sausagevore.tumblr.com is great, though no updates in a while. Also ghost-rooster.tumblr.com if you like captions (though most are consensual **********, which isn't really my thing). Also: bump!
https://imgur.com/a/QDa8zAh#ZHFcHxA has some great art on the topic. I'm not into the racial stuff, but there's good stuff here.
