Tetragametic chimerism, this is all to common nowadays two different sperm cells fertilize two different egg cells. Very common at college gangbang's where they have 2 dicks in her pussy at the same time. Now the daddy will be a tough one to find since he could be one out of a 100 or so men that weekend. The days of simplicity are over having to test just 4 or 5 guys for that month the deed was estimated to occur and then she might know their first names even sometimes.
The other thing is men back then didn't like their dicks touching other dicks during sex but now not so much for the young guys like us old hetero men who don't do reach -a-rounds to help out our buddy who's just come and needs boner encouragement to keep going, ewwwww.
