Burgundy:
the cane, on either end of it. What does it feel like?
Mmmkay, I'll try to describe it for the morbidly curious, though perhaps I ought to refer you to any number of fictional accounts in these 'ere shelves where this pain is delineated in the most exquisite of detail...
It's sharp, sort of slicey. Famously (or, for the morbid, notoriously), the pain doesn't register straight away, especially with the first stroke: there's the impact - fair enough, a thin stick has hit your buttocks, you feel that a bit - but then the sting emerges, and it grows sharper and deepens...and then it grows some more and radiates out from the thin line that's the source. Meanwhile, it continues to zing back and forth along that original stripe and may even (if you're un/lucky) start to throb as well. Frankly, you're surprised, especially if you'd thought that first impact was it.
(It's a favourite trope in caning fiction to record a first-time recipient's initial relief: 'Hey! That isn't so bad! What's all the fuss about? English wusses!' But, heh heh, then....

and....

)
With subsequent strokes (if you haven't already fled to the nearest cold water tap), you're already hurting so much that this delayed-reaction effect isn't so pronounced: the pain's fairly omni-present. And a stroke on top of a previous one tends to make itself known even more vehemently, as with any implement.
From the other end, it's a bit like your first driving lesson: you want to go very carefully in case you crash (your relationship). Depending on the cane, aiming can be tricky - they're usually curved and liable to swerve off and slice the thigh (and
not the kind attached to a drumstick). So it's best to get to know your cane by practising on a bottom-sized cushion first, before addressing the brave live peach before you.
Stance and positioning are also more of an issue than with other implements: ideally, with an upright, seasoned recipient, you're almost standing forward of their bottom so the cane swings into both buttocks, not just the far one (though the speedier last-six-inches, bending round, still tends to make the deeper impression - ouch! Mmmm!). Possession of a Certificate of Advanced Aiming is strongly advised before attempting this manoeuvre.
Last but best, the aesthetics: ah, yes! Even a mild stroke offers wonders of blossoming colour and geometry: bottoms vary, of course, and thank God, but a common sequence has an initial line of white turning pink and red within seconds; the skin puckers with dozens of dots and the red darkens; a ridge forms, and in time two 'tramlines' appear marking the edge of the stripe. There's bruising under there somewhere, but this may not emerge till much later.
Eh voila! You're spared the bother!
