After a major fight with a robot, Genos was infected with a virus that interfered with his artificial nervous system, making him heat up a little and his sensors go a little haywire.

It took him a moment to realize it was arousal. But his arousal only spiked when he was around you. Honestly, he could only think of you right now.
