Hermione felt the reins being pulled down to her new corset, as Snape’s Incarcerous Locus spell caused the reins to find new homes in the eyelets at the back of her corset, the restriction on her ribs was already so tight that she could scarcely afford the small whimpered exhalation as the new chains caused an additional fractional tightening on already severe corset bondage. The placement of the reins on the corset also meant that the remaining length of chain was directed downwards, lightly tapping her golden tattoo, each dangle made her wish she could flinch away in pain, but the two Death Eaters had her completely marshalled.
