"I got into doing gang bangs in 2008," says Shirley, 78, in the NSFW clip above. "I've done 14 of 'em since then. Each one is better than the last one." She then opens her shirt to reveal a tattoo on her breast (that's the real NSFW part of the video). I'm not going to tell you what it says because I want you to experience the joy of discovery.
