In one Clint is a slave owned by SHIELD. He is dating Phil, a free man, and gets sold to Tony a couple months before he would be free. Tony eventually sets him free and he and Phil get married.
The other fic I remember less about. At the beginning Phil is trying to recruit Clint and he gives him a business card and says it's his to keep. Clint isn't used to having things that belong to him. Later in the story Phil tells Clint that Phil himself belongs to Clint.
Any help would be appreciated!
