F/m, F+/m slave story where male arranges for mistress to dominate for a year

[mamtorsub]

Hi,

Its a fair few years ago now so details may not be fully clear but:
- male comes into money (I think) and decides to live out femdom/slave lifestyle
- advertises/contacts a mistress to dominate him for a year
- additional female slave joins the arrangement
- sign contract regarding limits
- progressively the two females (mistress and female slave) feminise the male slave but all is cleared by doctor/lawyer as in line with contract and no harm done
- mistress decides after a year (I think) to leave the arrangement
- the female slave takes over as the mistress
- male slave agrees

Not sure if I'm mixing this up, but pretty sure the story ends with male slave having to stand in a set location dressed as maid at behest of the mistress 

Long shot but can't find anywhere!

Thanks

Well if it's a Plaza story this search would be your starting point, 121 stories, fewer if you can think of other tags that might narrow it down.
