A lesbian couple was left red-faced after they were forced to go get help after a bondage session went wrong.

The Fifty Shades of Gay twosome, from Halifax in West Yorkshire, England, walked to a local fire station at 1.30am to explain they had lost the key after getting stuck in handcuffs.

Speaking to the Halifax Courier, Commander Paul Gyde said: ‘We found it amusing, but the girls looked embarrassed.

‘[The handcuffs] looked real and probably served the purpose for why they wanted them.’

The firefighters were eventually able to remove the cuffs from the embarrassed women in their 20s.

‘We were pleased we were able to assist them,’ Gyde added.
