Instant extra 1/2 inch from pumping.

I have a 2” LA cylinder which I fill up girth wise for the first few inches; under vaccum.

I have started to put a 1.5 inch ID, by about 3/4 inch wide cock ring at my base. When I go into the cylinder, I am an immediate 1/2inch longer. I don’t know if this would add to length over time, but I plan on continuing to do this.

I have been doing more pumping now; during the summer, and I plan on going back to more extending in the winter months, so I have a few months left for the experiment.
