You try to shield your eyes from the light and stumble, tripping over backwards. The light quickly fades, and you rub your eyes, your vision returning.
Before you was a tiny anthropomorphic unicorn. She had dark grey fur, a completely black horn, and orange hair flowing from the top of her head and in small tufts around her wrists and ankles that glowed with a bizarre light, making it look like flame. She also had hooves instead of feet.
Before you can gather your thoughts, the unicorn begins to vibrate, and with a sound like stretching and squeaking latex, begins to grow. Her growth spurt is powerful, but stops in a matter of seconds, as she stands up, a little unsteady. She towers over your height of six foot by a full eight inches, beachball sized breasts accidentally pushing into your face, forcing you to take a few steps back before you can actually see her face.
Nickering, she seems to notice the massive size difference between you, and takes a single step forward, the loud boom of her hoof connecting with the floor resounding throughout the room. She kneels to put herself at the same height as you, then stands back up, savouring her height of six foot eight inches.
Suddenly, she hugs you, easily lifting you almost almost a foot off the floor, accidentally pushing your face into one of her gigantic breasts, each of which is far larger than your head. Smiling, she sits down and places you on her lap, as you try to understand the situation.
So, do you want to continue this storyline, or start a new one?
