Bulls cumming in wives or girlfriend. Accepted or not?

My hubby loves it when a guy cums in me. While he's not a cuck one of his favorite things to do is listen to me giving a massage. Hid den if right next to the massage room so he's got a pretty good vantage point to listen in. He can tell what is going on. When I'm just massaging him, when I'm stroking and sucking his cock, if the guy is going down on me and, especially with the more vocal guys, when he's cumming. Knowing me as he does he knows that 99% of the time the guy is filling my pussy or mouth with his love juices.
 
cumming can creates pregnency but in many times at last moments cumming inside occurs , after cumming duty of cuck hubby starts to clean.
My wife can't get pregnant. After 7 years of trying it's official. So she never has to worry about condoms. Probably should be more careful,but she let's almost everyone dump their load in her cunt!
