Well, I went and did it.
I always had a fetish for pregnant women, especially unmarried more mature ones.
So I set out on a quest to find a nice mature woman, and I found one, one that never had kids.
We dated for about five months, she was still having a regular cycle so I tracked it and made a plan, and I emptied my balls deep inside her three straight days when she was ovulating. She really had no idea what I was trying to do, which was knock her up.
A month later she missed her period - I had, indeed, knocked her up! - she was almost 45. She wasn't happy at all, being an unmarried, church-going CPA Manager lady that was now pregnant - at her age.
We got married before she popped, and it sure was fun massaging her belly every night and watching it grow...
She would get so mad when I told her wait until we have kid #2....
