Source unknown – Title unknown (20XX)
Even though I suspect this is a composite–the dust scratches are not on the wall and they would necessarily move if that part of the frame were not a single repeating still frame; the wall and mirror are a mask, the mirror is transparent and footage of the masturbating boy has been strategically placed in such a way so as to appear as if reflected–it’s gorgeous.
Try an experiment: using both hands block your view of everything but the boy. Watch for a moment; then remove your hands. Note how the sense of vague exhibitionism disappears and a sense of voyeurism permeates as you consider the scene in totality.
Also, I like that he’s already orgasmed (you can see traces of semen on his abdomen), but he’s still stroking vigorously.
