Crichton can't help it, when Arthur goes for gold and tries to take him down all at once only to end up fighting his gag reflex for his trouble, Crichton lets off a breathy but very genuinely amused giggle. Here's the thing... that was frelling hot. Funny and sexy at the same time is such a goddamn turn-on for him. He probably should say that so Arthur doesn't die of embarrassment in the meantime.

"Arthur," he lifts his head so he can see to reach for his lover's (yes, lover!) hand. "I know I'm laughing, but I need you to know it's because that was one of the hottest things you've ever done. You're so cute and sexy at the same time. How the hell do you pull that off?"
