Yeah, last night I started thinking that thin black rope looked a bit like a power cord after I saw an older post with the wand setup. So then I figured it's some situation where that's on the stand and if he goes down far enough on the dildo, the weight hanging from his balls lets up a bit, but that's on his dick... and if he's told he can't cum for some amount of time, there's probably some kind of punishment involved if he does too soon.
