All in the Name of Science Pt. 03

... pressure to cum was almost helping me hold the squeeze. It's difficult to explain but I can hit that point and hold it for a good eight to ten seconds before the urge to cum becomes overwhelming. I don't always time the squeeze right, but this morning it was perfect. I felt the squeeze catch my orgasm as it was building. I felt the balance of pressure helping me hold the squeeze and then, when I felt the pressure overpower my PC muscle's ability to hold it back, I felt a powerful orgasm wash over me. Oh, and I came like a fountain. That's the other advantage of this little exercise. My cum shot powerfully from the head of my cock, shooting at least a foot or two straight up in the air. As the first volley fell back down, some landed in the device's jelly sleeve, providing a little more lubrication for me while much of it landed on my flat belly. The second shot went almost as high, but the third and fourth travelled mere inches before landing back on their source. Finally, I was done, but the machine clearly wasn't.

They were more like a bubbling stream than the powerful jets I had provided. Regardless, when he was done, there was no meditation in the world that would spare him from the sensitivity that settled over his abused cock. His volunteer, still stunned at being inadvertently knocked over, took an extra moment or two to right herself and turn off the machine. Other than a brief scream from its victim, the machine quickly quieted, as did the man laying under it.

Brendan impressively held out until this point before losing his composure and giving up his seed. He started by providing a long keening moan that gradually built in intensity. It abruptly switched to strong grunting with each jerk of his body and each shot of cum. "Fuck!" he yelled after each shot. After several strong convulsions, he finished and started twitching with the machine's strokes as his volunteer shut it off. In spite of the machine stopping, Brendan continued twitching with aftershocks from his orgasm.

At this point, only ...
