Many of my wives bf's have been my buddy's I served with while in the military. Quite a few of them, my wife, and I, would have loved having their babies.
Unfortunately, my wife was born with a form of PCOS (Polysystic Ovarian Syndrome). She simply doesn't produce an egg. Many doctors have told her it is literally impossible for her to get pregnant. Nevertheless, she still feels the urge.
So, yes. There have been many times, in our past, where my wife was actively trying to get pregnant from her bf. I would have been excited as hell, if one of my buds got my wife pregnant.
We have a similar situation......my wife has a "tipped uterus" which makes it VERY hard for her to get pregnant...…..not impossible, we have one wonderful and very successful ...... together but he was WORK!! I mean DAILY, multiple times daily, laying on pillows after so sperm pooled at the mouth of her cervix, every drop of sperm I could produce went in her pussy even if it didn't start there and she would put her diaphragm in AFTER sex to hold my sperm inside of her.
As a result, my wife has a pregnancy risk fetish. She started having affairs when our ...... was 2 years old (behind my back initially) and she was VERY lax in using her diaphragm with Lovers. She could easily be talked out of using it (she puts it in after they start playing around because it causes cramping), and its not long before getting pregnant is a LARGE part of her sex talk in her affairs. Her first affair was with a guy that had some medical background and they would play in his exam office on weekends or evenings and he would do "medical experiments" on her, like she would suck him off, hold the cum in her mouth and spit it in to a Toomey syringe, and he would then inseminate her like they do in fertility clinics!! If their affair had lasted longer I'm pretty sure she would have gotten pregnant by him but he got cold feet because his wife was asking questions about all the overtime he was working. They are still friends and he could start right back up where they left off if he wanted.
She also went thru a 3 year period of BBC FEVER!! It got so carried away that it almost broke us up (long story), but she was VERY lax with birth control then also. Other than not playing when she KNEW she was fertile, she did little else to avoid a pregnancy. She had one Black Lover that they decided they would stop ANY pretense of birth control and get her pregnant, but his wife found them out and they broke up before they could even start.......she was devestated!! Its only sheer luck we aren't raising an interracial ...... or two.
There have been others too, but her current affair is with her Boss/Lover. They have been together 10 years now, the first 2 years were behind my back (I suspected, not stupid) and a significant part of it has been totally without any birth control used HOPING for a pregnancy. In fact, the reason she told me about their affair (mostly) was because she came home form a whirlwind trip to Cancun together that was to celebrate their decision to transition from a part time only when they traveled for business affair, to a full time any time all the time affair. The reason she sat me down upon her return and filled me in on ALL the delicious details was because there was a VERY good chance she had come home PREGNANT!! And not only was it intentional, in order to be CERTAIN that it was his baby if she was pregnant we were not going to be having sex (intercourse) until she knew and she fully intended to continue trying with him every chance they got!! She assume that my cum flying everywhere as she stroked me off and divulged this to me was my acceptance of the situation!! LOL
To this day, the absolutely weirdest and most intoxicating phone call I have ever received was my wife calling me from her office at work SOBBING because her period started and she was not pregnant by her Boss/Lover!!! I was comforting my wife's sadness at not being pregnant by another man and assuring her that they could continue trying as long as she wanted it that way....I was ROCK hard, it still makes me hard just writing about that call!!
She is still hoping for a pregnancy with him, but has pretty much accepted its unlikely with his age (60's, failing health) and her tipped uterus requiring more frequent injections than he can produce but the still have a LOT of fun trying!! So much so that my sperm has not entered or touched my wife since November of 2012. I am required to use a condom if we have intercourse (rare), mostly she jerks me off with a condom on while detailing her most recent adventures with her Boss/Lover and I LOVE it!!
