You're sort of on the right track. But maybe he WANTS TO pull up so his balls get pulled... And maybe he HAS TO get fucked, by lowering himself further down on the dildo... There's something on the other end of that long rope that you see in the pics. And look at the black handle between his legs, what do you think that's part of? One more hint: I myself didn't release him from this predicament, ever. And no, I'm not a sick fuck that still has him like this in my basement, nothing like that of course. :-P Any other guesses?
