they dont even last till 28 even, id say early 20's is when the big naturals start to sag and droop. usually 22-24 ish. they can still be 'arranged' nicely by clothing...but the natural nubile and firmness of their youth is gone
I was with a Woman who had GGs, and they weren't droopy, very round, soft, yet firm. And she was in her 30s.
Fake boobs don't do it, the fact that just under the skin is a plastic bag full of saline, tends to turn me off. I feel like I am being cheated. Plus women act like they are the shit, when they are not. Go to Busty.pl ant tell me if fake ones are better than those.
