Christian takes you to a small clearing, ascends a stump, and sheds her clothing. Despite this being, more or less, your mother; you couldn't bring yourself to look away. It was then that, in a prismatic flash of light, a gigantic set of butterfly wings unfurled behind her back, snapping open in a colorful display. "I know what you wish to say." She began. "Do not be shy, my child!"
"You're a... f-f-fairy!?"
"A fairy Queen, to be precise." She turned around. Elegant gossamer fabric appeared from nowhere, and draped over her body; though it was so sheer, that one wonders what the point was. You noticed a natural eyeshadow and lipstick on her face; as well as body jewelry that grew from her skin, including where her nipples ought to be.
"I see you are not shy about looking," she observed, "that's good; it will make the transition smoother."
"Transition!?"
"Yes, I intend to make you a fairy like myself!"
"Like a... fairy prince!?"
She shook her head. "Unlike humans, fairies can only be female; and so too shall you become when you join me inside the gossamer flower, so I can transition you into fairyhood." A large flower with clear petals opened up beneath her feet. "Take my hand, and I will usher you into a fae life!"
