Yesterday was three years since my Cariad and I first exchanged cyber greetings. We went on to exchange erotic story ideas and then then co-wrote our first fantasy which just happened to contain a ruler, albeit a shorter imperial one...

The silence was killing poor Suzee. As she opened her eyes she saw him pick up the long, plastic ruler… Her eyes widened and she could not suppress a shudder as she took in the whippy eighteen inches of plastic in his hand and knew his intentions…
She longed to protest…
“How late were you today?”
She clenched her eyes shut and tried to control her shivering but hot bum and her dangerously wobbly legs and lied unconvincingly: “Five minutes”
Cooly came the reply: “More like twenty. We’ll compromise. You will take ten.”
She closed her eyes and clenched her cheeks waiting for the first smack of the nasty whippy ruler. The sound reached her ear a split second before the impact lit a fresh fire in her burning bum. She gasped aloud at the impact but before she recovered her breath...

...the fun way!

My Cariad has now managed to snap off another inch or so (I'm pre-Metric in my head)off the metre stick. It is now just under a metre and a bit nearer a yard stick in length. It is thick white plastic and very flexible

Funnily it breaks at end in his hand rather than end on my bottom! makes sense if thought about, as that's where it gets most flexed.

I guess it could denote an interesting variation on being 'hard-faced'
