[hprlsb.livejournal.com]

Hi, this is my first time posting and i'm looking for a fic in which John is a wub and the fic is set in an au verse where every sub needs a guardian. Sherlock becomes John's guardian at first then their relationship changes and he becomes John's dom. I remember one scene where Sherlock actually slap JOhn not too long after he was collared. I really hope you guys can help me cause this has been bugging me for so long. I hope i didnt imagine it and can absolutely confirm that it was a dom!sherlock and sub!john.

Model Sherlock, with photomanip

That should be failry easy to identify, I remember a lot of detail. :)

The story starts when Donovan gets her hands somehow on the old photos of Sherlock working as a photo model for male underwear. She shows them to John. John is stunned, because he used to have one of those photos (with no face visible) as a favorite wanking material for years. Sherlock finds out. Here my memory hits a blank, I don't remember if they are already together at this point, or the revelation serves to bring them together, but I remember that by the end of the story Sherlock decorated the bedroom in all photos from that photoshot, as a surprise for John. The story also had a photomanip or a drawing of the photo that John liked so much - Sherlock in black underwear, hands behind his back, head thrown back and to the side, so the face is not visible.
