Excellent wooly one! Sensual and sexy with none of the coarseness that many authors of bdsm story writing rely on.
The beginning is nice and easy, and so very well written and realist. Sheepish immediately lulls us (readers) into a most pleasant feeling of suspended belief as she prepares, with her written word, to expose us to the exquisite explosion of emotion that follows, or to paraphrase Widget, "...an earth shattering kaboom!" Well done!
Oh, and dare I ask, is this based on an actual experience pf yours?
