This is exactly how I want my wife to put out if and when she lets me watch her having sex with a friend. Of course, I will insist that she choose a friend with a huge cock and a very large cum load to ensure that she is properly inseminated. Then I will insist that she insert her largest Yoni egg to retain as much of his cum in her vagina overnight to let her body process his semen as nature intended. I suspect that purging the egg and the large cum load in a towel the next morning will show a huge rush of adulterous reproductive fluid that was inside her vaginal cavity long enough to give her doubts about remaining unfertilized.
