Thought it would be good to show this to those who haven't seen it. Apparently, it's pretty rare for a woman to have two uteri. However, when they do, they can in effectively be pregnant twice at the same time. Wouldn't it be great to be with a pregnant girl and be able to make her "more pregnant"? Anyway, food for thought.
