I am looking for a story in which a young male returns from initial training in the navy, and meets a woman in a bar. There's some exchange of words and then he is moved back to her remote ranch in her van. There is a mutual sexual exchange, and then he is held captive for some time, there are some electro-stimulation themes, and after some time he gets castrated and sold. I cannot remember whether there is a TG aspect to the story or not, but it sounds right.

I don't want anybody to go out of their way to find it for me, but if anyone knows offhand, that'd be fantastic.
