Pen's Nest

An Empty Cardboard Box.... could not be further from the content, which is Very Psychological And Worrying, but your answer sounds like it could have been a SeSa story from way back!

Fettered - spot on. The POV character (JC, if you're interested) is blindfolded.

A Little Bit Extra - is, I admit, a title that could be almost anything to do with JC, but the story is, uh, inspired by a foreskin.

Cocktail Party - actually, this one is Lambs. It was written for Lambs Day, in those halcyon times when we used to have such things, and features a Lance who's just back from Russia.

A Tale of Torment and Sweet Revenge - well now *I* want it to be about pirates, too! Drat.
