I keep watching that gif. It's mesmerizing. And I have so many questions. Who is the dude? How did they train that fish? Or was it a one-time occurrence? Will the fish just leap up and latch onto anyone's nipples nearby? Did the dude plan for this to happen? If so, why did he lurch out of frame? Was this a staged porno? How many people have jacked off to it? Is it technically sfw? Could the fish be CGI? What's with the tail wiggling as it tries to bore through his body? What the fuck? What the fuck? What the fuck???
