Added 2020-09-29 08:57:31 +0000 UTCSince a lot of people ask me this question I want to say that I use a electric pump to hold the vacuum in my cock pump. That’s quite nice since you don’t need to care about the pressure and you can just concentrate to the feeling to get sucked. The pump does up to 330mbar below athmospheric pressure and you can believe me that this will suck the last drop out of you ? I think that normal pumps can reach only up to 200mbar. As far as I know there is only one supplier in the EU who manufactures such a pump with a reasonable price. Or do you know others ? In any case I can really recommend it. Meanthile I use mine for 5 years and it still works fine. And I use it a lot ?
The brand name is “”Froehle vacuum pump” and the tube fits to almost every cock pump (seems so be a standard connection). Here is the link: https://www.froehle.de/en/sp003/ I wish happy sucking ?
