She wasn’t sure how much time passed.  She tugged instinctively at the restraints but from the feel of the metal shackles there was no chance they would give.  After what felt like an hour (though was probably actually much less), Lucius came into the room and released the nipple clamps.  She let out a shaky breath around the gag in her mouth as he gently rubbed the tender nipples with his thumb.  He released her hands and bound them behind her back.  It was a relief to lower her arms.  She never had liked holding them above her head for long.
