I believe this may have been discussed on a limited basis before, but what the hell, good topics never die........
Imagine a gang bang involving several strangers in a cheap motel room.
Participants would have to bring valid proof that they are disease free before the event would take place. Beyond that, everyone would be completely anonymous and untraceable. After the wife/fiance/girlfriend has taken fertility haves for the prescribed period of time, the meeting would be arranged. She would spread her legs and take load after load of hot bull cum deep inside of her twat.
A pregnancy would be quite certain from that point (if not, there is always a chance for more bulls and more bangs as time went on!

) and the cuck hubby would not only be raising a kid that isn't his, but one who is quite literally 'manless' in the traditional sense.
