Here is a site with feminization stories. He will send you one story for free but then has many more stories for sale for five pound Sterling each. I have only read the free story. Strange stuff but very well written and engaging.
John Titles This is a story of John who moves into a B&B, run by a domineering woman and her mother. They normally had female lodgers who helped with housework but agree to give him two weeks probation to see. He ends up helping them and their neighbor with housework and is then forced to do more of their bidding. Eventually being sent out in drag to the postbox and then taken to the WI in a pretty apron dress.
