Turn It On, Tune It In (Let It Out)

Can't help but bury his face in her underwear and lick. Has some hesitation over doing something so vulgar, but he just can't stop himself, and then takes it up a notch when he wraps her panties around his cock and works them up and down, feeling the way the soft cotton slides against rigid throbbing flesh, panting as he takes himself closer to the brink of orgasm...

Kallen calling Zero to discuss something with him, and of course Lelouch answers, still jacking off in her bed. Manages to keep his voice and breathing relatively even, but a little noise gets through nonetheless, and Kallen has a moment to spare towards Zero doing that but quickly dismisses it as ridiculous. Zero would never. After all, he's a professional, right?

Oh, Kallen, if only you knew.

Lelouch first getting obsessed with Kallen in R01E03: The False Classmate, when she accidentally reveals herself in the shower. He quickly and quietly snaps a pic or two. It's just an urge, an impulse, a desire that comes over him without warning or mercy. Plus, he's never seen a naked woman before until now, even if it's only for a flash of a moment.

He doesn't even really know why he did that, but there's no denying that he's attracted to her personality as well as to her body.
