Many MANY reviews say "great breats with responsive nipples."
I can't say I've ever been with a woman who with stimulation her nipples didn't get hard at all (civy or hobby). Have I just not met the right (or in this case) the wrong woman?
Some women don't like their breasts played with too much or they don't like the sucking of the nipples.
Then you have women who can orgasm just by having her breasts played with.....sucked on just the right way, squeezed the right way. That's where communication comes into play.
Myself.....LOVE lots of attention paid to my breasts and yes, I can orgasm from it.
