Are you using any kind of lubricant? I have used and made all kinds of domes and have yet to use one or make one that does that. I just use a body lotion of good hand cream on my breasts before i put them on. and those pumps are pretty crappy. And you really don't need to use one because the normal human can draw as much vacuum as you need using your mouth as that pump will produce. I don't even use the air locks but use a fish tank air valve and manually sut them after I reached my desired pressure. Make the system tight enough that I can go 4 or 5 hours over night without pumping. I also use an automotive vacuum line from the auto parts store. I hate to have to pump, and pump, and pump!!
