I have had the honor of sucking on both  real and fake  d and even dd  melons , the fake  are  stiffer  and maybe not as much fun , not as much bounce ,  In my opinion  which is worth nothing I know  ,  It all depends  on what your looking for , if you want to look good dressed up  or at work and you want to use your boobs to help  your business career  Id go fake , if your just doing it  to go bigger , I wouldnt spend the money ,  As a employer of several  employees its hard to turn down a  applicant when she comes in and has a ample cleavage  and you realize there is no bra holding those perfect things up ...    but for pleasure  I think  real is the way to go  ... ... ..

and yours look very nice to me  

Ive had both.. sucking on them isn't different in the nipple area so much as it is when trying to suckon the sides!!   Hey the sides need love too.. but both fake and real are great.. ive had my fun with both..

Real, fake, what ever they all taste the same bring them on.
