One year, for her birthday, Fran's partners/bandmates, Tatsuko and Elise, bought her an incredible gift to show their love and commitment: an enchanted blue rubber bodysuit, with attached collar… or perhaps it'd be more accurate to say it's stored in the collar?
Upon donning the collar, Fran was no longer able to remove it; only Tatsuko or Elise can. The magic that runs through it enables either of her partners to modify the suit's configuration as they please with a simple touch, whether that's changing the gloves to mitts, adding a hood, or even turning it into a bitchsuit. If need be, either may retract the suit into the collar, though this has happened very infrequently in the years since Fran put the collar on, and the collar itself has stayed put on her neck since the day she accepted it.
One of the suit's various enchantments keeps Fran clean, so that she can wear it 24/7 without any hygiene concerns. That's not to say sweat and other fluids won't collect at all, but they're cleaned up within a day, and any germs are eliminated.
By default, the suit has two sheaths: one encasing Fran's cock, the other allowing penetration into her ass through the suit. These sheaths are stretchy, able to collect her cum not unlike a condom and stretch as deep inside her as need be, respectively. If desired, Elise or Tatsuko can reconfigure the suit to cover Fran's mouth, adding a third sheath headed down her throat, perhaps even far enough that it meets and merges with the sheath in her ass, creating a rubbery tube through her entire body.
