What story does this picture tell you?
Mmm my first reaction would be to say that the Sir on the left put his boy’s little nub in protection for his own safety, and that he wanted to have a picture for him to commemorate the day it became permanent. However, I noticed that the erect boy is shaved too so maybe he’s not the Sir, but another sub. Perhaps this photo was taken by their keyholder as a comparison shot to show to other Sirs who are thinking of doing the same thing. Or maybe…I got it, it’s a photo to show the two states of male slaves available at a popular BDSM club. Either way, I’m willing to bet that the locked boy dropped to his knees afterwards and serviced that erection until someone pulled him off of it.
