“Do you have any idea what's about to happen to you, Twilight Sparkle?”
“You're going to... you're going to...” She knew exactly what he was planning, but she couldn't bring herself to say it. The fact that she was to be executed seemed almost unworthy of note compared to what was going to happen right now.
She felt his glove on her rear, not in a sexual way but in a commanding way. She then felt a pin prick into her side.
“What are you doing!? Stop! Stop!” She shouted at him and tried to shake herself free, but she soon felt a sharp pain as something was injected into her. Her body grew hot and her thoughts started to become incomprehensible to her, like she was reading fine print on a rollecoaster. “Wawawhat are were you going to doing to me?” She slurred her words as her thoughts all mixed together. Her panicked confusion slowly started to give way to a strange, dull, bliss as the gravity of her situation started to leave her mind.
She didn't get an answer, but instead she felt something soft wrap around her horn. Unlike before, she could feel all the sensations she would normally have been able to feel and more. She winced as it slid down her horn and neatly settled at the base.
“You know, I've always wondered if a unicorn's horn was an erogenous zone... judging from your reactions, I'll say that it is.” She felt the softness start to move up and down in rhythmic strokes, squeezing and softening its grip at the same time.
“That feels gooood... I mean, what did you do to me!?” She yelled as if she had just been woken up from a dream.
“It's all just a little experiment. Please bear with me for just a minute.”
