When a stepmom enjoys a stepson’s cock in her pussy, there is no stopping them from having sex every day or night when there is enough privacy to have sex. I suspect that if the stepmom is fertile and not using birth control, she most probably will become pregnant at some point in the family affair. That won’t be too much of a problem as long as her husband hasn’t had his nuts clipped. That scenario caused a scandal in my wife’s family when her sister turned up pregnant and her husband had a vasectomy. We all knew who the sperm donor was when her sister confessed the affair. After that, my wife decided to have sex with the same man just to remind her sister that she wasn’t the only wife who could cheat on her husband and get away with it. That same guy tried to knock up my wife and she went along with it at the time, but she later admitted that it would have been a big mistake and was glad she remained unfertilized.
