The words Knicker, Arse are the british word for ass and pantie.
I realy don't have a problem with them. Does not bother me one way or another.
But the thing that drives me insane like finger nails on a chalk board is when in an other wise good story when the submisive or for that matter dominant talks about her "Cunny".
If you are going to say it say it "CUNT" REPEAT "CUNT" not "cunny
Men do not call there "cocks", "cocky" We can be cocky and we can go off "half cocked". But we do not call our "dick's" "dicky" or our "penises" "peeny"
I hoped I have made my self clear and the next story that has cunny in it the author will be caned on her "cunny"
