These girls are HUGE and heavy.  I absolutely LOVE them!!!!  For me, I need a 40N bra.  Fills the cups; maybe a 40O would be better, but that's a harder bra to find.  These boobs are soft enough to feel real.  They are well made.  With a good bra, you won't feel they are too heavy.  These boobs are a dream come true.  The only thing better would be real boobs or implants.
