My wife was 37 when we meet her lover and did not use any contraception cos I had cut my strings a couple of years before, after our third ....... Her lover was not able to have kids cos of low sperm numbers or something like that, so he always fucked my wife bare and squirted his cum freely inside my wife just as I did (my wife loves to be fucked bare and feel cumshots inside her..), but I have to emit that it turned me on that he COULD have made my wife pregnant on a sort of perverted way. We even talked about it back then, what we would do IF he got her pregnant, but never decided anything.
My wife's lover cums A LOT too, his cum is thick and sticky and I love fucking my wife in it after he had giving her his huge load so I never wanted him to use a condom, I wanted him to cream her up real good. I don't know about you, but watching and listening to my wife's lover cum inside my wife is just fantastically arousing, watch how he trusts his bare cock deep inside her while he grunts and moans in pleasure while his cum splash out deep inside my wife... I love it! And it feels right to let him cum inside my wife, even back when he could have made my wife pregnant..
