It’s a good thing that momma Nata had the boy use a condom and then withdraw to ejaculate the family love seed because the boy had a huge cum load that was probably seething with millions of sperm cells just willing to fertilize mom’s womb with a taboo fetus. However, if they have sex often enough, she is going to “slip up” and get “knocked up” in the heat of passion during a n intense session of unprotected intercourse. That is nature’s way of surprising the most cautious of lovers regardless of their relationship.
