OK. Now I really want to know what else the black rope was for. It's difficult to see properly but jimmycontour has made it clearer. I certainly think those boxes can be spread to their fullest extent to lower the boy just a bit further. Looking at his dick that wand on the stand could come in useful, letting him reach it when he's as low as he can get to give a bit of relief, just a small gift for impaling himself to the max and pulling his tits as bgpcf has suggested.
