Bark for me boy! The tighter I tie his leash down, the harder it is on his knees to keep himself standing. With each stroke he chokes himself out. Aww, poor boy, it feels so good but he can't even get close because the distraction of his leash takes the focus away from cumming. Self denial, or is it me? Technically it's his choice to be distracted. Tehe.

Not PETA approved.
