Looking for somewhat Dark John/Rodney fic

Hi, I looked everywhere but could not find it.. I remember that somehow Rodney sleeps with John and John is not happy (I think I remember that John thought Rodney took advantage of him) so he forces Rodney until he realizes what he is doing and Rodney is not happy and only allowing him because he felt bad about what he did.. Thanks in advance...
