Imagine her womb being flooded with pig sperm. Interspecies cellular contact between sperm and egg. The sperm count and motility alone would probably wear down the uterus’ immune defense response. Repeated insemination from one of the most genetically compatible non-human species would probably render her uterus incapable of fending off any more sperm, giving them free range to penetrate the outer layer of the egg, should a lucky bovine sperm be able to find it. Perhaps the sheer number of pig sperm would mean greater chance for interspecies fertilization to occur.

God that's so hot

That was an absurd amount of cum

I want my pussy to be filled with cum too.
