Castiel's grace was something that you always took for granted. It's part of who he is, and it's what juices him up to heal you. That's it. That used to be the extent of your thoughts about Castiel's grace. Not that you don't love him and everything he is, but you never really focused on his powers. Because, for you, his powers don't really make him the angel you love. Now, you're not so sure if you're indifferent to his grace.

"Cas," you groan sweetly on his ear, your walls tightening around his width. You're on the edge for the third time that night. It's so glorious you can barely breathe.

"Come on, one more time." His raspy voice does wonders to push you closer, but it's his grace that does the trick.

You don't know how, and quite frankly, you don't care. The magical substance wraps around you almost with the same force Castiel's arms hold you close. Even if you cannot see it, you can feel it in every inch of you. You never knew angel grace could be used on such occasions, and perhaps Cas didn't either. He's as on edge as you are if the delicious grunts are any indication.

Feeling the climax building up, you bring your lover closer to you. Your nails scratch his back in a way that if he had been human, he would be bleeding. He pounds in and out of you just the right way. And when his grace slips to your clit, as if caressing, you completely lose it. The knot building in your belly snaps and all you see is light.
