When Magnussen pissed in the fireplace, John was outraged; Sherlock, on the other hand, was just a little aroused. Magnussen noticed.
A few weeks later, after Sherlock comes out of hospital, Magnussen summons him to his office penthouse. Using the Watsons, and particularly John, as leverage, he forces Sherlock to kneel down in front of him, makes him take off his scarf and open up his coat, and then proceeds to urinate down his front, soaking his expensive white shirt and tailored suit.
Sherlock feels utterly humiliated, but Magnussen isn't done with him yet. When he has relieved himself entirely, Magnussen shakes himself dry in the direction of Sherlock's face, then orders Sherlock to undo his flies and take himself out to masturbate. This reveals that the ordeal has actually given Sherlock an erection, much to Magnussen's very vocal amusement.
Magnussen dismisses him at that point and a frustrated and humiliated Sherlock tucks himself in and runs from the building. Unable to take the Tube or a cab even with his coat closed due to the smell, Sherlock walks home, but the memory of what was done to him, and the state he is in now, make his arousal return and he finishes himself off, rubbing his soiled crotch, before he even makes it home.
Up to author if Magnussen summons him again for more messy domination games, or if Sherlock is simply haunted by the experience and ashamed that he found it so arousing, and has fantasies about it happening again.
