When a mature woman wants sex, it doesn’t matter whose cock is providing the pleasure as long as she is willingly taking it. And if she gets pregnant in the process, it’s just nature taking its course. A fertile woman can be impregnated by a friend, a relative, or a stranger and her womb cannot distinguish the difference between family sperm cells and any other mans. It’s always a risk in the game of sexual pleasure according to my shared wife’s confessions.
