From what I can tell so far, it seems Irina is trying to figure out a way she can get some of that Issie Cake and not become a fallen angel. Of cousrse there is that "Promised Day" thing coming up, but here's a guess:

The Flaggelettes!

During the dark ages a group of monks went from town and attoned for their (and the town's)  sins by whipping themselves as they walked and chanted. I'm guessing/hoping that after her sexual desires start causuing her wings to flicker more black than white, Irina decides to seek absolution for her sinful thoughts by having Akeno whip her with Holy Lightning while she (loudly) confesses her deepest desires! After a session of this, she has received the "Absolution of the Whip" and Irina's wings are all nice and white! Now Irina has a way of being with Issei and not falling. How this get's incorporated into their physical relationship is something I will not describe here. That would cross the line from ecchi to hentai! But that would be one erotic as hell scene!
