When I move up in dome sizes I typically have air escape in the sides as well, but if you use a good amount of lotion or cream, whatever you are using to moisturize before pumping, oil, etc. USE PLENTY be VERY generous with it, make it so much your breasts look soaked in it!! Then you may have to just keep pumping for a while, until your breasts get use to it and expand. I know it's a pain but there is really no way around it, none of us have the same shape as the domes lol. Typically my breasts get completely use to a new dome size within a week or two to where I don't have to pump every few minutes to maintain suction. Hope this helps and good luck!
