This guy has a bizarre fixation with flat-chested women comparing tit sizes.
When you tell him how weird it gets seeing it get so much focus in his stories, should he find out you're a flat-chested girl, he'll blame YOU for finding his fixation weird.
If you explain that you're proud of your flat chest, he'll accuse you of lying to try and further the "get out of criticism free card" he desperately WANTS to think he's found.
This implies his obsession with flat-chested girls comparing their tit sizes is based on a hatred of flat-chested girls, rather than a love of them.
Why he's so obsessed with girls who have a body type he doesn't like being ever-present and comparing their tit sizes in his writing is beyond me. Sadism?
Heh, well, I'm terribly busy at the moment and have almost no time for drawing. I'm either in class or at home taking care of my baby boy and preparing everything for the coming of a new baby girl. It'll be a while still before I have time to draw again sadly.
"Hu", indeed.
