I did some time in Prison and spent a few weeks experimenting on creating my own device from what was at hand, which wasn’t much..
I found a paper clip, which I heated up and used to burn the bottom out of a shampoo bottle, slowly, and one hole at a time.I then smoothed the plastic as best as I could with the heated paper clip, so there were no sharp edges.I then put a hole in the top of the lid, and covered it with the finger of one of the blue cleaners gloves they use inside. I was very pleased to find that the rubber of the glove acted as a one way valve.So basically, I would get semi hard, put my cock in the shampoo bottle and squeeze the bottle while pressing it tightly against the base of my penis.
The finger of the glove would inflate slightly, releasing some air from the bottle, and then deflate tightly over the lid of the bottle, making a seal.The plastic of the bottle was firm enough that when I squeezed the creases out of it so as to return it to it’s original shape, a vacuum was created, and by repeating the process, I could get a very decent pull going. I found that an extended session became painful around the base, due to the thin edge of the bottle.
After much experimenting, I found a great solution. We would get a piece of fruit every day, and at least twice a week it would be an orange. I cut an orange in half, and made a hole just big enough to accommodate my erect cock.I then put my cock through the hole so that the cut side of the orange was against my body, and my cock coming out of the hole.I would then do the same squeezing routine to get the pressure up.this worked quite well initially but I would have to keep squeezing the bottle as the seal wasn’t so great and would only last five minutes before the skin would break, and the bottle would get sucked through the orange. I tried an apple but similar problems occurred..
Eventually I realised that by reversing the orange so that my cock was coming out through the flesh of the orange and the curved part was against my body, I had done it! The flesh of the orange helped to make a seal, and the comfort was amazing. I could even re-use the orange several times. I eventually realised that I didn’t even need the rubber glove, but by opening the lid slightly as I squeezed and then tightening it again before squeezing it back into shape, the same effect was achieved..
Now that I’m free again, I thought I could improve on it, but the only thing I’ve changed is that I use a thick donut of latex instead of an orange, and the bottle I use is see-through, and slightly longer.Yes, I did achieve length and girth in the 5 months I was there; about an inch I’d say and maybe 15mm in girth
