I am looking for stories where a sub (or preferably a slave) is to go under the knife unwillingly and the sub/slave does (or at least tries) to jerk off for one last time before going under the knife.

For me it looks like it is the most logical thing to do is to try to have sex or jerk off when I realize it is some for my nuts to go.

Any good stories, from the old or the new archive?
