I'm trying to figure out how her body is positioned on the other side of that PC, and I can't.
She's kneeling with her waist rotated about 75deg and her shoulders turned to be 90deg from her hips, then her breasts are so huge they've been sloshed over even further on top of the computer so that they're "perpendicular" to it's side. That said, they don't appear to be the same size.
