The most primal moment imaginable! Knowing that your seed is quite literally claiming her womb for you, its intoxicating. The only thing that can make it even more so is if she is married and you are owning something that is supposed to belong to someone else.For me, it's about the extreme intimacy of being claimed and owned at that moment. No matter how much society wants to confuse or blend roles between men and woman the act of having a man cum inside me feels so primal. It makes me feel so owned at that moment.
