from the Amazon specs, I can’t tell if those are 13cm wide or 15?   And what’s your bra band size?   I’m assuming that your 33” is your bust.  Which if your a B or C cup would put you at around a 30” band?   My breasts are also widespread and I need help more help on the bottom.   Did you try doing one at a time?  Even at 13cm, they may be one size too big.  And you probably should not have contoured.    My domes are about 11.5cm and not contoured.  And I have had good luck not using lotion in my entire breast, just the part I want to increase.   Leaving the top of mine dry so it does not pull that part of the breast into the dome.   You would leave the bottom of your breasts unlubed.   And try doing one at a time. 

Look at this dome size database I started years ago and see where your domes fit in.  https://www.breastnexus.com/showthread.php?tid=19940
