Putting it in Awkward Sex pool because Portland is thinking about Indy, saying Indy's name, and saying that she wants Indy to make her pregnant.
While it's still awkward, that's not what happening here, she's thinking about how she wants 10 children (for now) and how she wants all of them to look like Indy (basically her love affinity line in game). She just went a step further and made her commander help her out in such an "endeavour".
