Stairs scenario

hey, long time watcher first time poster, basically came up with this scenario a few days ago, quite simple really. So what you do is find a nice set of stairs, preferably indoors and carpeted, at the bottom of the stairs hang a key from a piece of string then run the string up the stairs, still out of reach and tie it with a very simple bow knot. So now in order for the key to drop the knot has to be undone. Now what you do is go to the bottom of the stairs and tie yourself in a way that makes your crotch strain while your hands are behind your back, personally i’d do this in female clothing (i’m a guy) including lock on heels . Now add any toys you want and climb the stairs, undo the knot to make the key drop and go back down the stairs to get em:p hope you like it, enough positive comments and i may consider making a video and taking some pics of this and showing a select few people;p
