Well to add more length you have to leave it on longer like 15 minutes and then release the vacuum and and then do it again for another 15 minutes and so forth
But if you want to make it fatter release the vacuum every minute or so.
I have a powerful pump to make it fatter though. I use a compressor I got off a mini refrigerator you know one of the small refrigerators but didn’t have to pay for it because it didn’t cool any more because the Freon leaked out and I got it free.
If you are lucky try and find a small refrigerator it works great to make the penis have more girth. Believe it or not all I use to lengthen my penis is a pump I got at a dollar store to pump up rafts with. I just put a aspirin bottle over the end and put a whole in it to put the tube that goes in to the cylinder. Hope that helps.
Don’t use a refrigerator compressor for lengthening the penis use something else although you could use it if you have some type of valve so it don’t suck that hard. Because if you leave it on a long time when there is a lot of suction it will give you penis blisters so you really don’t need to have a lot of suction for the lengthening part just have to leave it on a longer time. When ever you can leave it on longer than 15 minutes without releasing the suctions will greatly improve the lengthening process.
I made penis enlarger for a friend on time and he used it and fell asleep with the pump still on his penis and slept for about 2 hours and when he awoke his penis was stretched to about 9 inches the first time he used it he had about a 7 inch before he started so he gained about two inches the first time he used it but kelp it on for about 2 hours or so. The longer the duration is the longer it will get but do not start at 2 hours before releasing the vacuum try releasing every 15 minutes or so but slowly build up longer times to wait to release the vacuum.
Good luck
