Identify Comic/Hentai Request (need help remembering title)

[Shoopdoop]

The only scene I remember involved a young, male priest who was traveling and came across a succubus who was imprisoned. He eventually freed her and then enslaved her with a ring or something.

I've been able to find it a few times, but I never seem to remember the title.

Thanks.

Maybe it's this Sei naru Fukuin, I only know the title in Japanese
