Following on from the success of sugar-daddy dating sites such as Secret Benefits and niche fetish sites such as Only Feet, a recent court case has highlighted another such site - Prison Benefits, which is less well known.

Apparently a hot custodial officer at the Parc prison in Bridgend Wales was having daily phone-sex with an inmate, which should not be possible as inmates are not supposed to have phones.

The lady in question claimed that she was listening most of the time while doing the ironing.

Their 'innappropriate' relationship ended when the inmate tried to get her to meet his mother. Despite being on trial, the former officer is now on OnlyFans and earning a fortune from ex-offenders paying for photos of her eating porridge in her stripey pyjamas.

Former Australian convict Bill "Ned Kelly" Heslop told FNN:

Good job they didn't have mobile phones when I was inside. We had to do everything by telegram.

Hey Muriel! Fetch me a tinnie. I'm parched.
