It was a pretty good length story, about a guy who woke up naked in (I think) a cage, he'd been kidnapped while changing a woman's tire. It went on with him at one point begging her to use a strap-on on him, she told him he had to stay in the belt a year. Then at the end of the story she tied him down, and soldered the lock shut, and melted the key in acid... I remember it being well written, and I can't remember where I found the story, but would love to find it again... Any ideas? J
