It was clear Ruthie wasn't happy with the awkward position she was bound in. So if she was going to complain, I would give her a reason to do so. A single rope is all it takes to go from awkward to very uncomfortable in a matter of seconds. Tight crotch ropes tend to have that effect. At least I'm kind enough to dangle the magic wand in just the right spot. Now it's a matter of choice. Succum to the vibrating pleasure and let herlegs go weak or hold herself up to keep pressure off the crotchrope. I'm sure Ruthie will figure it out.
