"Stop—"
A chuckle.
"Steve—"
Squirming, shoving, laughing.
"I'm trying to look over this file—"
Steve grips his partner's hips, nosing at the neck of his t-shirt with a smile and earning a surprised laugh in response. He knows Phil has work to do before they sleep, knows that the man does not put play before work, but the mood had struck him and given the lateness of the hour he figures that Phil could stand to give himself a five minute break.
"And you can finish when I'm done," Steve murmurs, tugging the collar of the agent's t-shirt down.
"Don't stretch the collar, I like this shirt," Phil complains.
"Mm. I won't," Steve answers, lips meeting bare skin.
He kisses along the length of the shorter man's collar bone, listening to Phil continue to discuss his plans for the meeting tomorrow even as his fingers find their way to Steve's hair. Phil's sentence is cut off with a surprised yelp as Steve bites, sucking until he bruises the skin. The soldier pulls back to admire his handiwork. He grins from ear to ear as Phil pulls his collar aside to try to see it for himself before looking up at Steve with a vaguely amused expression and a raised eyebrow.
"Another one?" he asks. He clucks his tongue.
"I'm following the rules," Steve says. "Nothing above collar level on your work shirts."
Phil sighs through his nose. Well… at least he had followed the rule. He'd noticed early on that Steve had a certain fondness for marking him and Phil certainly wasn't about to stop him. Still, it doesn't explain just why Steve does it so often.
"The last one already faded away," Steve says, apparently finding the question written on his face. "So I thought it might be a good time for you to take a break from that paperwork."
He reaches out and taps the rim of Phil's glasses.
"You'll strain your eyes."
Phil snorts at that.
"I think they're long past the point of being saved from strain. May as well go down with the ship," he says. He eyes the mark again. "You know, you're the reason I have to change in my office whenever I use the gym."
Steve knows that very well. He knows because he's often waiting in Phil's office whenever the agent returns from said gym. He dips down pressing one more gentle kiss to the agent's collarbone.
"Fine by me."
