Twilight's Swap-Half-a-Body spell is put to some more interesting new uses:
It can give two lesbian lovers something new to play with. It can let the two of them feel what the other feels like. It can even help a scorned Princess of Love release her frustrations on the lot of them! And, of course, everypony will have lots of fun along the way.

Updates will be daily.
