Step-Siblings in Control
Our parents left us in charge for two glorious weeks, and it was finally time for some payback. My step-brother, the golden child, had always been daddy's favorite, despite him being twice as far away at college. They trusted him with the responsibility of looking after me while they were gone, and I couldn't wait to show them just how much of a screw-up he really was.
A Surprise Visit Home
I snuck into the house, surprised to find it a complete disaster. He had trashed my room, and I could hear the sound of him puking in the bathroom. I couldn't help but grin, my camera ready to capture every moment of this debauchery.
As I moved through the house, I caught sight of him on the ground, still heaving. I laughed and pounced on him, pressing my boot down on his chest and reveling in his helplessness. "And what do you have to say for yourself?" I taunted, my voice dangerously low.
He looked up at me, fear and loathing in his eyes. I knew I had him right where I wanted him. "I-I'm sorry, sis. I didn't know how to handle it." He stammered, his voice barely audible.
That was it. I had enough of his pathetic excuses. It was time for him to learn his place. "I think you do need some help," I said, my voice sweet but cold. "I have just the thing to make sure you never fuck up again."
Shrinking to Submission
I pulled out a small, shiny object from my pocket, his eyes widening as he saw it. "What is that?" He asked, his voice trembling.
I smiled, my heart racing with anticipation. "This, dear brother, is a shrink ray. And I have plans for you." I placed the ray on the ground and stepped back, watching as he scrambled to his feet.
"You're not serious," he whispered, his eyes glued to the tiny device.
Oh, but I was. "Trust me, you are about to get very serious." I stepped closer, holding out my hand. "Come here, little brother. It's time for your punishment."
Assumed Positions
He hesitated for a moment before taking a step forward, his eyes never leaving the shrink ray. I could see the fear in his eyes as he slowly knelt before me, his head bowed in submission.
"Spread your legs," I commanded, my voice ringing with authority. He did as he was told, his face turning red with embarrassment.
I aimed the shrink ray at him, feeling a thrill run through me as I pulled the trigger. The ray hit him, and I watched in awe as he began to shrink before my eyes.
Shrunken and Submissive
He shrank down to the size of a doll, his tiny body trembling with fear. I picked him up, marveling at his miniature form. "You're so cute like this," I whispered, running my fingers through his tiny hair.
I placed him on the ground and knelt down next to him, my face just inches from his. "Now, brother, it's time to show some appreciation for your sister's help." I ran my tongue along his tiny ear, causing him to whimper.
I leaned in closer, my lips brushing against his tiny cheek. "From now on, you're going to stay right here, in my panties. And every time I sit down, you'll be right in my ass crack, reminding me of just how much you owe me."
Conclusion
The two weeks passed by quickly, with my step-brother living inside my panties. He was constantly at my beck and call, always ready to lick my ass or kiss my feet. And every time he looked up at me, I could see the fear in his eyes, knowing that this was his new reality. It was a powerful feeling, knowing that I had complete control over him. And although he hated every second of it, he also couldn't help but feel a strange sense of gratitude towards me for giving him a purpose.
