Glad you like the story and my style of writing.
I always try to use the English language to the best of my ability, as I hate using the same word over and over again. Writing in what is effectly a limited field (i.e. bondage), it gets difficult sometimes to think of new ways of saying the same thing (e.g. 'she was tied up'). So, for example, rather than use the word 'bound' time after time, I'll use tied, tethered, fettered, manacled, shackled, restrained, immobilised, trammeled, encumbered etc. etc., which I think makes reading more interesting. (Not everyone would agree with this)
According to the Global Language Monitor website, there are an estimated 1,025,109.8 words in the English language (how you can have .8 of a word, I'm not sure), and my aim is to use the lot! (Well as many as possible, anyway).
