He needs to get his sister and a cousin pregnant, they both have boys that will keep it program going after he is gone. (You fill in the story line)
I say he has mostly daughters cause the males are obviously rare and it isn't until he is a grandpa (though still his daughter too) that another make with the right cum is born. That would be at around 40 and then someone else would be helping before he his 60.
6⭐️s!!! If I had any say in the matter, I’d be expecting 40 more chapters! Fucking excellent story!
Surprisingly good story really far fetched but still good. He should be breeding all of them that are able including his mum and aunts if there not to old.
