I liked it. It's a fairly obscure pairing but so good.
I only had one nit picky moment and that was the irish cursing.
"T'anam an Diabhal."
It doesn't make any sense. The only curse that's close to it is "In Anam Dé" or "Anam Dé". None of the irish curses really involve the devil, most revolve around the other celestial sphere. I know what you were going for but it just jarred. Sorry.
But I loved the touch of the nipple ring and the evolution from comfort to relationship still based around comfort and helping each other out.
