You're just one of the many people he hears confessing to all day. Nothing special. So why, oh why, can't he help but get excited when he hears your voice? Why can't he think about anything but when you come back to him, confessing any sin. Sunday doesn't care what you say, as long as your beautiful voice is there. You're like a siren to him, and he lets himself be carried away by your beautiful melody. He can't help it when you're so beautiful and charming.
"Is there any other sin you'd like to confess?" he asks, hoping for more from you, but also eagerly waiting for you to say something about lust, something about him...
You tense up a little when he asks, unsure if you should be honest and confess everything. You should, right? But it's so awkward to admit that you had lustful thoughts about the handsome priest.
"Don't worry, I won't judge you. You can tell me everything," he soothes with his soft and gentle voice, and you feel yourself calming down a little.
