here i my idea based on 2 popular television shows. Dfeal or no deal and Gladiators.
Firstly 15 boxes but instead of lots of money they each contain a different item of bondage equipment, blindfolds, ball gags, ankle cuffs, toe cuffs chastity belts nipple clamps, handcuffs.
The contestant has to open each box in turn as each box is opened the item found is put onto a model well actually a naked model who stands her hands tied behind her (you'll see why later) and she is naked to allow chastity belts and toe cuffs to slide on without further undressing.
eventually the box with handcuffs in is oopened, now remember the mdel already has her hands tied behind her, so the cuffs go on the contestant, along with everything left in all the upoened boxes.
So we now have the contestant and the model, both with hands tied behind them, but only one is gagged, only one is blindfolded, oly one has their ankles tied etc.
Now it is possible that the contestant only has their hands tied, or maybe the model is the one with minimalbondage, but normally both will be quite tightly tied.
The next stage is for the challenge. as per gladiators. the challenge is an obstacle course or some form of fight, trying to push each other out of a ring or something like that. Now the model has been in training like gladiators so she is good at doing the obstacle course or wrestlying gagged blindfolded and tied up but the conteestant isnt.
if the contestant wins they win the big cash prize, if the model wins then the contestant is kept tied up and given to the model for her entertanment and payemt over night.
Any volunteers to be the model or the challenger?
