"Ah, jeez..." The fairy groans and rolls her eyes as she restores your height.
"Oh my gosh, thank you, thank you, thank you so mu--" You look at the fairy, look back down at your body, and look at the fairy again. "Hey! You just restored me back to your height!"
"Come on, now, I wasn't gonna let you go that easily." She pushes you down, and with a wave of her wand, fabricates a translucent chair behind you. You land in the chair softly.
"Wh-what are you doing?"
She pulls out a pendulum and swings it around. The moment you lay your eyes on it, you cannot pull them away. Not long after that moment, you fall into a deep hypnosis-inspired sleep. While you are asleep, the fairy programs your mind to make you more like a pet; more like her slave. She tells your subconscious that your mind, body, soul, and life belong to her and her alone. You are to refer to her as Mistress from now on, and for the rest of both of your lives (and, if possible, in the afterlife).
Shortly after her reprogramming, you awake, feeling more blissful than you ever have before. You look at your clothing, and it seems that Mistress has now donned you in a maid's outfit, including black-and-white striped thigh-high socks, and a collar to go with it. The chain on the collar is being held by Mistress, obviously to make sure you know she is your owner, and that you can never run away from her. However, you both know that that thought would never cross your mind.
"M...Mistress?" You ask your fairy owner.
She gets a surprised look on her face for a second, as if she just noticed something. "Right!" She bursts, raising her pointer finger as if she just had a eureka moment. "I never even told you my name!"
"Oh my!" You exclaim.
"It's Destiny, by the way." She giggles. "But you'll be calling me Mistress. Of course, you could use Mistress Destiny... or 'owner'..."
"Oh yes, of course, Mistress!"
"I won't need to know your name. I'll just give you a pet name, since you are my pet now after all." She thinks for a second, and then has another eureka moment. "I got it! I can call you 'Princess'!"
"Yes, yes! I love that!" You respond, as you stand up and hug your new master. She kisses you gently on your forehead, and it sends a slight wave of pleasure throughout your body, probably because you just made your Mistress happy enough for her to reward you with her affection.
"Now, come along, Princess!" Destiny pulls you with her end of the chain on your collar. This, for some reason, gives you pleasure like before. You moan sensually, and start walking right behind her, ready to begin your new life as Mistress Destiny's pet.
Not really though.
I'm sure there's more to add to this story branch, involving the adventures of Destiny and the princess. Maybe Destiny gets eaten by a snake, and the princess wants to always be with Destiny no matter the circumstance, allowing them to be digested together! The possibilities are... well, not endless, but they aren't extremely limited either.
