Sorry had to mention both for representing one of the sexiest aspects of woman/mother-hood. Thanks to the ladies and their gents for sharing their motherly beauty.
The truth is out there...the great un-acknowledged fetish is the great love many men have for the pregnant form. Perhaps it is some perverse mix of love of mother, love of a woman who has an undeniable history of fucking, the opportunity of sex without the risk of pregnancy (because she is already pregnant)and the fantasy/truth that a pregnant woman is a horny woman. I don't know for sure, but I love it.
