Delta P Danger
James and Barney were working as deep water divers inspecting pipes. There was in intermittent loss of pressure that they were trying to identify. They were following the pipe and checking suspect areas.
Barney was born right around when the cartoon started and has caught flak for it pretty much his entire adult life. One of the results of this is that he will often try to do silly and stupid things to seem more manly.
They came across a section of pipe that had some build up on it, they checked that area and didn’t see any leaks, but Barney saw an opportunity. The build up on the pipe, from the right angle, looked like a plump pair of ass cheeks.
They have devices on hand for taking pictures and they have been given leave to take some personal pictures of things they find interesting while they’re down there so long as it doesn’t take too much time from the actual job. After they confirmed there was no active leak in the pipe, Barney positioned himself to look like he was humping the build up.
The pipe had been pumped down so there was nothing in it as this would increase the overall pressure and aid in finding any leaks. What they didn’t know, as there was nothing running through the pipe was there was a defect in the pressure fitting where this build up was happening. That defect caused a notable noise while there was active flow through the pipe, and that noise drew in curious animals. Those animals would press against the pipe causing the defective section of seal to slip and open a breach in the pipe.
Barney was straddling the pipe, the position of the gap in the build up happened to be precisely where the defect in the seal was. With Barney pressing himself against the pipe, when he shifted in just the right way, his cock and balls were perfectly lined up with the seal as the defect shifted.
James didn’t understand initially what had happened, he was waiting for Barney to say he was in position and suddenly barney was screaming in his mask and had thrown himself from the pipe. Moments later James saw the trail of blood following from Barneys crotch.
Barney was in position and had just turned to be looking at James when he felt the most intense cutting feeling he’d ever felt along with the feeling of being kicked in the balls. He instinctively pushed himself away causing the pipe to seal itself again. He knew he’d been badly hurt, but not how bad it was. They both immediately went to the recovery area.
Once they were in the recovery bell and were able to get the suit off of Barney did they see how bad it was. There was a little bit of flayed skin around his crotch, but his cock, balls, and sack were entirely gone.
James had to do some emergency work to stop the bleeding, but a proper surgeon would be needed to fix it all. The nerves and blood vessels were an absolute mess meaning a false penis wasn’t a viable option. Enough of the urethra managed to survive that they were able to attach it and create an opening to see through, but he’d be sitting down to pee for the rest of his life.
