The first thing that came into my head when the big guy showed up was "It's not what it looks like!"

But then I thought about it, and it's actually WORSE than it looks like. Mostly naked guy, tied up, chick messing around with his remaining clothing... So.
"A little privacy please? we're kinda busy right now!" then, when he didn't leave "Hey- you didn't pay me to gawp!"

I figured if he caught sight of the priest it'd look even kinkier!
