Send her home

"I think I'll be fine now, Imogen," you reply. "You get off home."

You might be imagining the slight moue of disappointment that flits across the young beauty's flawless face, because she responds happily enough, collecting her things and saying goodbye as she lets herself out. You head upstairs to get ready for bed and are about to turn in after finishing your nightly ablutions, when you notice a cabinet in your bedroom that you don't recognize. Inside, you find all manner of spanking accoutrements and even some bondage gear, which leads you to take a look around the rest of the house to see whether there are any other changes.

The most obvious difference is how clean and tidy everything is, but the only other thing you discover is that your cellar, which used to be used solely for storage, now contains a whipping post, apparently for when you decide to inflict a punishment so severe that the recipient can't be expected to submit without disturbing the neighbours.

Your curiosity satisfied, you return to bed and despite the excitement of the day, soon drift off into a restful sleep.
