Dean had fallen asleep on his front tonight. His arms were wrapped around a pillow, lips parted and back slowly rising and falling with every even breath. His bronze skin seemed almost pale in the moonlight, each freckle standing out in sharp relief.
Cas smiled and ran gentle fingertips over Dean's warm skin. He traced meaningless patterns with his fingers, connecting the dots over and over again. Dean didn't stir; his body was so used to Cas's hands and presence that he didn't register as a threat, even with Dean's finely honed hunting skills.
Cas loved it, especially since this lapse in Dean's defenses is what allowed Castiel to carry out this little ritual.
There were precisely one hundred and seventy-six freckles across Dean's back and neck, some so light they nearly blended in to Dean's tan and others so small they were next to invisible regardless of their color. But they were all there.
Cas moved closer and pressed his lips against the warm curve of the shoulder blade closest to him. He concentrated and let just a hint of his Grace seep out, burrowing happily into the top few layers of skin and curling in on itself. In the morning, Dean would have a new freckle.
On Dean's back and neck, there are exactly one hundred and seventy-seven freckles. There are fifty-eight across the bridge of his nose and cheeks. and fourty-four peppering his shoulders and chest. Twenty-three decorate one arm and seventeen the other. Three daring freckles rest along the smooth curve of Dean's ass. There are thirteen up his right leg and twenty-two down his left. On his feet are eight freckles.
They all add up to a year's worth of nights spent in Dean's arms.
"Happy anniversary, Dean," Cas whispered, closing his eyes and moving closer to his lover.
