You always knew you were meant to birth a monster. When I wasn't turning into one fast enough, you decided you had to help things along.
Not all at once, maybe a curse with a painfully graduated onset, or something subtle you slip fractionally into my food every day.
It does happen fast, though. I start to get bigger, taller, centimeter by centimeter, and my muscles grow too. My clothes start to get tight on me, first in a sexy way and then impractically, and I cry when I can't fit into them anymore but you tell me you'll help me find more, and your heart rate raises as you can see veins start to grow defined beneath my skin. My hair grows longer, down from my scalp and up from between my legs, soft and wiry and furry, and I'm so embarassed at it peeking out above my wristbands and creeping down my spine.
My emotions start to spin out of control, my teeth sharpen, my nails grow hard, I keep breaking things, hurting myself on accident, being horrified when I scratch someone too hard or break the skin with a bite by mistake, and I panic and I break down and I curl up in your bed sobbing and I'm too big for you to get her arms around and even though I'm crying it makes you so wet. And I can smell it. I can smell every part of you and not just you but everyone. I can tell by scent where every ovary within a quarter mile is in its cycle but I don't know that and I don't know what that means and all I can smell is blood and sweat and need and pheromones and when I break one of your bedposts from grabbing it too hard, desperate to restrain myself, the look in your eyes is hungrier than even I have become.
And I am horrified by what I am becoming and you have never been more aroused and you buy chains and silver and tell me that it's going to be okay, that this is normal, that mommy knows what to do, and you train me to be safe, to control myself, to be controlled. By her. For everyone's safety.
And you teach me that the only safe thing for me to do, what I HAVE to do, is let her take care of my new massive knotted cock that won't ever go down or stop throbbing but it's too big for anyone to take and it's too much and you can't help but tease and chide and punish me for being so needy and monstrous and I can hear the muscles in your cunt twitch when you do and I need you to break my mind until I give up on being good and let you corrupt me into a monster of a daughter that isn't good for anything but breeding her mom so full that it hurts and the cum goes everywhere and curling up chained in a cage at the foot of your bed every night and devouring every man on the street that looks at you wrong.
