Mysteries of the Universe.

I remember this one time I was at my friend's house and one of his friends was over there, this white guy. He was messing around on his laptop and he wanted to show us a porno so he called us over. He logged on to his account at BigBlackCocks.com and started playing a video. I couldn't get over that. I kept wondering, why does this guy have a membership to BigBlackCocks.com? He's not even black. I didn't even watch the video. I just stood there staring at the back of this guy's head, puzzled.
