A steel bondage hogtie is bad enough ... Jane's wrists and ankles held together by the unforgiving metal cuffs,. But chain elbow bondage ... her elbows scrunched together, as if her arms were welded together ... rope, though tight, might flex a little. But chains? Once they're wrapped in place, they don't move ... the only thing they do is leave brutal marks.
Especially where there is lots of struggling ... and Jane struggles. Hard. It's Jane vs. the steel bondage. Which one do you think wins?
