"Oh..." This game of want and teasing and denial is the sweetest like this, when he knows he's wanted and its being prolonged for the both of them, not merely one. "The punishment is tempting as I trust you... But I want the reward from behaving all the more. I want to see your joy in the result, and so I keep myself as still as I can. My body, my cock follows your demands and I watch you with hungry eyes, licking my lips and wanting your permission so badly I can taste it."

He's behaving in the scenario... But here, in reality, he lifts his hips off the bed do he can scoot his leggings down and let his cock be free. Even more, be visible. Zevran knows what he can do to Anders, but seeing that? Always better.
