So I decided to try some different cups.
Here are the ones I got: Amazon.com : Elitzia Vacuum Cups for Butt Lifting 3000ML/101Fl.oz Vacuum Cupping Machine Accessories Extra-Large Buttocks 9.05inch bottom diameter 6.69inch height 1 Pair ETHX005 (Peach) : Beauty & Personal Care

Here are the results.

Those are some amazingly impressive results you've achieved!  I'm assuming that with the size of those domes, you're only able to pump one at a time.  I really like the shape of those domes, I think it's better than the more conical shape of the domes I'm using. 

Best regards,

For comfort, I do one at a time. Also when you do it this way, your able to pull more of the inside of the breast in and after have much better cleavage.

Oh my those are the biggest boobs wow did you get such lovely boobs by just pumping. W ould love more details on how you did it

I dabbled in PM a couple times. But mostly pumping since 2007ish.
