A German couple had to call out the fire brigade after tying each other up in chains - and then losing the key to the padlock.

"It was so embarrassing. We just wanted to try something a bit different and we ended up with this!" said the poor dear...

"I even had to be taken to hospital because my wrists had swollen so much from trying to get out of the handcuffs."

Emergency help came to their rescue to find them wearing naughty leathers and chained each other to their beds, minus the key, and after hours of struggling to become free.
