This is a classic story by the internet writer known only as “MrSpraycan” – first posted to Usenet circa 1997. He was a remarkably good writer, kinky as all get out and versatile. Not your usual junky dialogue, but stuff that'll make you say “that is one well drawn and seriously perverse dude”. He's missed . . . I can't recall whether there was a Part 3 or not . . . this is all that I've found.
To be %100 clear – not my work, and not claiming it as mine . . . but definitely wanted to applaud this kind of artistry, we don't see kinky writing of this quality all that often. Definitely on the “harder” side of BDSM, some scary sounding threats, but not actually doing it. Still, if you like your domination gentle, maybe not the perfect story for you . . .
