Bigger feels good.
The only safe place to start using it was in the attic and although I couldn't inhabit the attic every night, there were several times a week when I could 'vanish' and pump!
The first time I used the pump I was very excited and my cock was getting big as I anticipated what would happen and what it would feel like. I put my well lubed cock in the pump and started to pump. The size of the pump was 1.3/4 inch diameter x 8 inches long. My cock was only around 1.1/2 inches so it didn't fill the tube. Length was around 6 inches. The seal was good and as I pumped I could feel my cock being sucked down the tube. A new pumper was advised to only pump for about 5 - 10 minutes at the start and increase the time daily by 5 minutes to a maximum of 30 minutes a time. This felt good as after 10 minutes I took the pump off. My cock didn't look very much different but it felt good so after about 5 minutes I tried it again - and again! After three times I was getting used to the feelings generated and wanted to pump for longer. At the end of two weeks I was pumping for 30 to 40 minutes and wanting to go for 60. My cock was loving it and I noticed that my donut was starting to stay swollen. My shaft was still thinner and I wanted everything to be uniform in width. I persevered and gradually my shaft grew thicker. My knob had grown a lot and was now quite a bit bigger; my donut was swollen and I couldn't push it over my knob. After a few days, my cock returned to normal, but not quite! I was definitely a little fatter, a bit longer and my donut was a lot bigger. I had to carry on - I was becoming addicted!
