From the Avengers Kink Meme: http://avengerkink.livejournal.com/11065.html?thread=24876857#t24876857 "So Clint is Phil's sub. And he's stubborn and insolent and gets in trouble fairly often. He's always implying that he and Phil are really hardcore, and after a rough patch where he gets punished a lot, his friends start to worry for his safety. In fact, Clint is the gooiest, subbiest sub that ever subbed with Phil, who is incredibly gentle with him and heavy on the pampering and praise. Clint basically lives to be petted and told what a good boy he is, and his punishments are things like timeouts and very light spankings with Phil calmly telling him how disappointed he is in him, which is enough to bring Clint to sobbing contrition. So I guess there's some voyeurism or something, I just want this dynamic and the world at large seeing a radically different one. All the bonus points for some compare/contrast with Pepper and Natasha who are outwardly nearly vanilla when in fact they do crazy edgeplay and heavy pain and just don't tell anyone about it."
