But she does it 'affectionately', LOL XD
No, no, if it had been affectionate, Asuna would have called him piggly, but instead she calls him based on how she sees him, which is a disgusting pig, and Asuna likes disgusting people and wants to be just that. I can only say one thing: Asuna and Inoda are beyond redemption, not even a good psychologist will save them.
One last thing: When Asuna isn't having sex, does she call him affectionately, or does she only call him that when she's having sex? Has Asuna ever said she loves Inoda even when they're not having sex, or only during sex? It makes me think that Asuna says things during sex that I don't know if she would ever say in a normal situation, and I don't know if she has the courage to walk arm in arm with Inoda while others are watching, unless she's so used to it that she doesn't care, but that's not possible since she did it all in secret.
