What shall I say?
If you can't see it, where you have to grasp, because you must turn your back to the door and you can't use your fingers, it could but be a problem to open a door even if it has a door handle;-)
And Amelie's exquisite tight crotch rope with all her knots, will also not help Amelie to concentrate during she shuffles forward;-)
But till now is this beauty doing it very well;-)
And her captors will for sure use a shorter chain between foot cuffs, a much tighter crotch rope and a tight red latex bolero straitjacket the next time;-)
But maybe a institutional straitjacket will fit better to Amelie's institutional foot cuffs?
