Sometimes, metal bondage can be so simple. The RigidFiddle model 'oo' is a brilliant piece of engineering. To be stuck in one doesn ́t seem to be very harsh, but as Shenenne finds out: it is very frustrating to be locked in this device for a couple of hours! Especially when the keys are available and it turns out she still can't escape. We just sit back and watch! Just a few hours left, Shenenne!
