It only took mere hours for the fatberg in the sewers to grow in size. It had surrounded and attached its self to a rusty pipe that had been mounted to, but hung from the ceiling. The fatberg had wriggled around a little bit, not that anyone noticed, and had accidentally discovered that the pipe felt good It was as if it was stroking its penis in its other life. And so the fatberg continued wiggle and wiggle and wiggle until it felt something attach to the end its pipe. It couldn't identify what attached to its pipe, but the pipe felt slippery exciting the fatberg even more. And so the fatberg rammed the pipe into the moist confines of what ever was attached to it. At first, the fatberg released some sewer gas into the pipe before it sent a torrent of sewage through the pipe to where ever it went. It felt release, but it was ready to go again and so it started thrusting the pipe again.
After that initial experience of belching and throwing up, the toilet had eventually started associating belching and throwing up with pleasure. And so, resigned itself to its fate of ecstasy and pleasure.
