That is an interesting question, to which I am sure there will be members who can bring first-hand or first-bottom experience. I presume that this is a literary question, so my answer won't necessarily be helpful, coming as it does from the perspective one who makes toys for sensual purposes, and that in the present.
The thing which needs to be considered is the effect the implement will have on the three parties to the spanking transaction - primarily the spankee, but also the spanker, and thirdly, any observers there may be, which I imagine, given the setting there may well be, either visual or aural.
From the spanker's POV the implement mustn't be too severe. This may appear counter-intuitive, but the punisher (for in this setting we are to assume that it is punishment we are talking about) needs to feel that effort has gone in, that healthy whacks have been given, that the job has been well done. So thus we are talking quite thin, about probably 1/4" - 3/8" but crucially, big for maximum visual impact before the action starts, and acoustic impact after it has started (so the listeners can hear how bad the spanking sound is). A thin, less dense paddle gives a higher pitched sound than a thick dense one and whilst it doesn't carry so far in acoustic terms, the snappy sound is worse. Perhaps boxwood would be suitable, though this is difficult to get in large enough pieces for a paddle.
From the bottom's POV it wants to be as pathetic as possible, say 1/16" thick and made of papier-mache or expanded polystyrene.
From the observer's point of view, there are competing requirements. The smug tell-tale sister wants her being-spanked little brother to get it as hard and as long as possible, so she will require 3/8"-1/2" thick and a dense material like oak, walnut or perspex. If, however she is watching the spanking knowing that she is next over the knee then of course her requirements are similar to the spankee's - see above. |
