I cornered Diana in a hallway on her way to lunch. I asked a simple question. "How are you today!"
Diana shrugged, her silky black hair flowing over her shoulders. "Good I guess. Waking up alone in that classroom was weird but I've gotten over it."
As Diana spoke, her utterance of the word "butt", however nonchalant, was heard by her ears, and my trigger caused her ass to grow a little bigger. It was barely notable, but I could tell her butt was jiggling just a bit more. Fiening ignorance, I continued the conversation. "I can imagine it was uncomfortable. Buuuut things happen, right?"
As I experimentaly stretched my programmed word, I saw Diana's ass grow for as long as I said the word. Her ass had become incredibly big already, both cheeks the size of basket balls and sneaking peeks out from under her skirt. This trial run had proven fruitful, so I decided to reset Diana's commands for now. "Bread Curtains"
My one of a kind keyword sent Diana into a state of sleepy stasis in which she would follow my every order. She fell against the wall, and I held her by the arms to support her. "Forget all your current commands."
"Yes... Master... " Diana's slurred voice droned.
"now, if your Master, and only your Master says listen, you will freeze in position, and focus only on your Master's voice. Whatever I say in this state must be obeyed. Understood?"
"yes... Master..."
"Good girl."
And with those two magic words she woke up in my arms.
After school, I found Diana under a secluded bus stop upon an equaly deserted street. She was sat upon the bench inside, with her hands upon her lap. I noticed her ass was still very large, and remained visible even while she was sat down, her skirt simply an inadequate size to contain it's bloated girth. As I approached, I saw Daina notice me, and immediatly recoil into herself. I sat beside her, close enough that I could feel the heat of her blush, and close enough that I was pressed up against her overflowing ass. I was the first to speak. "Hey princess."
I felt Diana shudder, the flabs of her ass jiggling as well, as she replied quietly, "Don't call me princess, please."
I continued, "When's your bus?"
"18 minutes apparently."
"What a coincidence! Same here! Listen." Diana froze stiff as a cutting board, her body still as a statue, yet still entirely relaxed. I moved my hand under her skirt and over the surface of her ass, feeling its soft tenderness in my palm. I looked to her soft delicate face, and told her, "Your name is princess. It has always been princess." I thought for a second, then continued, "Whenever you hear your name, you will begin to gain an urge to grope your ass. With each repetition of your name, this urge will only grow greater, and greater, until it is unbearable." As I stared into her blank, glassy eyes, I had one final idea for 'Princess', "When your master gropes your ass, you will fall to the floor. From this point onwards, when you try to get up, you will instead get on all fours and stick your ass out over your head. You will not understand why you cannot stand up, and the more you question why, the bigger your ass will grow." I waited a couple seconds for the commands to sink in before I finished the induction with, "When I snap my fingers, you will wake up and remember nothing about being hypnotised." I then snapped my fingers.
Life returned to Diana's eyes, and she looked over at me, her long black hair falling over her face. "What... did I fall asleep?" She asked. I decided to test out my new commands. "Yeah, for a minute or so. But hey, at least you're awake now, Diana!"
She stared at me with her brow furrowed, and replied, "Who's Diana?"
I placed my face in my hand in mock embarrassment. "Sorry, just someone I used to know. Don't worry about that Princess."
Suddenly, Diana's face flushed violently, and her hands twitched slightly upon her lap, and yet she resisted her strange newfound urge. I smiled at my success, and asked my blushing companion, "What's wrong, Princess, is something bothering you?" This time her hands moved instinctively to her rear, but she stopped them quickly, and moved them back to her lap, her eyes looking away. She spoke quietly, her voice shaking from her desperate resistance. "N-no, everything's f-f-fine..." I whispered into her ear, "Are you sure, Princess?" Now Diana herself was shaking, tears falling from her eyes over her bright red face as she gripped herself tightly to avoid going for her own butt. I sighed, leaned away, and gave one final push. "Alright then Princess, keep your secrets." I hadn't even finished my sentence before Diana got out of her seat, sobbing deep tears, and leaned over, clutching her ass, and began to thoroughly squeeze it within her tiny hands. She massaged her rear, groping every inch of her large, wide buttocks, it's flesh overwhelming her fingers and bouncing wildly. From where I sat I watched this magnificent display in all it's glory, as her pink panties strained, barely contained within her round cheeks. Watching with a satisfied glee, I decided to help Diana with her activities, and I reached out my own hands to grope her ass myself. I grasped each cheek, and clenched, letting the waves of fat overflow around my fingers. Diana herself was suddenly caught by a wave of vertigo, and fell to the floor, her ass falling out of my reach. Through tears, she cried, "What's going on?" As, in her attempt to stand, she clambered onto her arms and knees, and thrusted her rear into the air, like a dish served right into my lap. Her skirt fell down away from her ass, like a curtain coming down to reveal the show. I dug my hands into the flesh of her butt, and massaged it's fleshy girth, as from down below I heard Diana whimper through her tears, "please stop, you're making my butt feel... weird..."
