"I found something interesting..." said John.
"Oh?" asked Sharon.
"There's a Succubus costume in the closet. I think it might be your size."
"Let's take a look."
John led Sharon by the hand to the closet at the back of the room where a three piece Succubus costume hung. It had donkey like hooves, donkey like legs from where the hips are down to where the ankles where and that where connected to a tail that ended in arrow pointed tip, a headband with a pair of donkey styled ears on it, a second headband with a pair of horns on it and a bra that look like it could hold a FF-cup breast and where connected to a pair of huge bat like wings.
"It reminds me of a Good Succubus from 'the Chronicles of Wargonia'" said Sharon. She pulled the costume off the rack and laid it out before her on the nightstand. "And it does look like my size except the bra that is."
"Another hotel perk to go with the Medieval theme." After a moment, John added "Want to try it on? I think you'd make a sexy Succubus."
Sharon smiled. "Let's find out."
She then took the whole costume to the bathroom, laid it out on the countertop, and explain to John, in a no-nonsense tone of voice, "Let's keep it a surprise for now."
She closed and locked the door behind her and considered the costumes legs and hooves. She had worn sandals so she had bare feet already. Sharon pulled her panties and the rest of clothes off. She slid her legs into the donkey-like legs and slipped her feet into the hooves. Her feet fit somewhat awkwardly into the hooves. A long zipper along the back of legs made it much easier to the legs up her legs than it would have been otherwise. The tail had a comfortable feeling and it felt almost real when she reached back and felt it to make sure it didn't fall off her backside. She then considered the bra. Normally, she would have asked the receptionist if the Hotel had another size, but she wasn't in the mood to deal with the flirting receptionist downstairs so she put on. The result was a bit of a surprise for her anyway: the bra shrank itself down to her B-cup breast size. Finally, Sharon put the two headbands on, with the donkey-eared one towards the top of her head and horned one towards her forehead.
What didn't she know was that she herself was already starting to change. The hooves were already melting her bones in her feet. But she should have notice and been concern about how neutral the costume felt. But that was for later. Regret in hindsight, as they say.
But does John and Sharon do...
