Looking for an very old story!!

         I am looking for an old inflation/expansion story where a male scientist/ doctor kidnaps a woman in a revenge style plot, then ties her up in restraints on either a research lab or surgical suite.  He subjectes her to BDSM style water/fluid torture by filling her bladder and bloating her bladder/belly slowly.  Her bladder gradually gets to the size of a 55 gallon drum or greater.  I can't remember where I originally saw it.  Does anyone know of this story and/or have the source archived?
