“You were born to serve. To live is to serve.”
“Kim -”
“I was born to serve,” my sister cooed. “To live is to serve.”
“You exist to serve men.”
“I exist to serve men.”
I took a step forward, my body shaking. My heart was pounding, and I felt dizzy. This wasn’t normal behavior. Even for a joke, I knew my sister would never go this far.
It’s not like she’s a bra-burning feminist or something, but…this wasn’t Kim. She’d always been independent. Like, she’d once told me that she hated the way Mom always did the dishes, even on nights when she’d also cooked.
And yet, here she was, kneeling on the floor, her head bowed and her eyes fixed on the TV.
I stood behind her. “Kim,” I said, shaking her shoulder.
It was like I wasn’t even there.
“Kim!” I repeated, louder. “This isn’t funny.”
My sister didn’t respond, and the voice on the screen continued.
“In life, it is the duty of a woman to please her master.”
“In life, it is the duty of a woman to please her master.”
I could see my sister’s face, now. It was expressionless as it stared at the small screen, her eyes bright as she repeated the lines back.
“You will kneel before your master. You will do as he commands.”
“I will kneel before my master. I will do as he commands.”
I considered shaking her again, but I knew there was no point. The only thing I could do was turn off the video, stop this insanity.
But as I stepped towards the TV, I noticed something.
I was hard as a rock.
I should be clear – I’ve never had any attraction to my sister before. Even if I’d ever noticed her body (which I hadn’t), I probably would’ve told you that she wasn’t my type. She’s short – really short. And skinny. And it’s not like she isn’t cute; she actually has a pretty face. She’s got a light dusting of freckles, and dark brown eyes that always seem to be looking at you.
But I’ll admit it – in that moment, she looked hot as hell. Every inch of her body was tense, like she didn’t want to miss a word coming out of Kiki’s mouth. Her skin was flushed, and I was suddenly aware of how much skin her shorts and top showed off.
“You will submit to your master,” Kiki’s voice continued. “Alone, you are nothing. But with him, you will find purpose you never dreamed possible. He will give you purpose. He *is* your purpose.”
“I will submit to my master,” my sister echoed, and I looked at her eyes as she spoke. They were wide open, trying to absorb every lesson coming from the small television. “Alone, I am nothing. But with him, I will find purpose I never dreamed possible. He will give me purpose. He *is* my purpose.”
God, why was that so hot?
It shouldn’t have been, right? It shouldn’t have been a turn-on to watch my sister kneel on the dusty attic floor, drinking in everything the video had to offer.
She was my *sister*.
“You will kneel before your master,” Kiki said firmly. “You will do as he commands.”
“I will kneel before my master. I will do as he commands.”
I was convinced that she wasn’t faking. Not only did my sister not have the imagination for a prank like this, it just wasn’t her style. She wasn’t a prude, exactly, but…well, I knew she’d never had a boyfriend. Our parents had said that in exchange for them paying for college, we weren’t allowed to date until we graduated.
“You will do as he commands.”
“I will do as he commands.”
“Your body exists to serve him.”
“My body exists to serve him.”
The comment forced me to evaluate my sister’s body. Like I said, short and skinny. Not my type – I’m more into, I dunno. Christina Hendricks. Tall, redheaded, busty.
But as my eyes travelled down my sister’s form, I had to admit…maybe I’d been judging her a little too hastily. She was in pretty good shape, after all. She jogged regularly (it apparently helped her with the Harry Potter thing) and had a nice curve to her hips.
Her stomach was soft, but it was flat. She had a small, pouty ass, and her legs were long and smooth. Her breasts were small, but she wasn’t wearing a bra under her tank-top, and I could see that they were round and firm.
I blinked twice. I absolutely shouldn’t have been looking at my sister like this. She was my *sister*. I needed to turn the tape off, snap her out of it, and then…I dunno, burn them.
But as I took another step forward, the voice said something that made me pause.
“Your master stands beside you.”
“My master stands beside me,” my sister gasped, her eyes flicking over to me for just a moment.
I froze. Had…had the tape just named me as Kim’s master?
In a moment, I could see it. I could see my sister, unquestioningly obeying my commands. Doing as I said.
I could see her kneeling at my feet, just as she was now, waiting for my command.
I know how wrong that is. Even in that moment, I knew how wrong it was. But…my cock was hard, and I was breathing heavily, and I was staring at my own sister’s body. My sister, kneeling on the dusty attic floor, pledging her commitment to me. To serving my needs.
Pledging to obey her master.
“Your master will take care of you.”
“My master will take care of me,” my sister echoed, her voice strained.
“You exist for your master’s pleasure.”
“I exist for my master’s pleasure.”
“You are his,” the video continued.
“I am his,” Kim whispered in response, and the tape ended.
Chapter 2
I just watched, hard as a rock, as my sister continued kneeling in front of the TV. Neither of us said anything; I just watched her, noticing the swell of her breasts as she breathed, the slight tremble in her hands, the softness of her lips as she silently repeated the lessons that the video had taught her.
“Kim,” I finally said, my voice hoarse. “Are you okay?”
“Yes, master,” my sister said, a moan in her voice. “I will do as you command.”
I blinked twice. Surely it couldn’t…she wouldn’t…
“You’re sure? You don’t need to…”
“Yes, master,” my sister said. “I am ready to serve you.”
“Stand,” I ordered, and Kim obeyed. Her head was still bowed, her gaze fixed on the floor.
“Kneel,” I instructed, and Kim did as I commanded, her knees touching the carpet.
“Hands behind your back,” I added, and Kim followed my instructions, pulling her arms behind her back.
I took a deep breath. “Turn around,” I ordered.
My sister complied, shuffling her knees as she slowly rotated, keeping her eyes on the floor.
How far could I push this? How much of this would she remember? How long would the effects of the tape last?
I wanted to tell her to strip. I wanted to tell her to expose her body to me. I’d never seen a naked woman before, and Kim was…look, I know she was my sister, but she was so willing. So eager to please me.
So keen to obey her master.
I leaned against the attic wall, my eyes travelling up and down my sister’s body. She would strip if I told her to, I was confident of that – the tape had commanded her to obey, and I was certain that she wanted to.
She wanted to obey.
But for how long? And would she remember what we’d done?
What if it wore off, and she told Mom? What if it wore off and she told everyone?
I glanced at the suitcase. This tape was one of three. If this was the only one required, if this was enough to turn anyone into a willing, obedient sex slave…why would there be three more in the series?
No. No, I couldn’t risk it.
Not without knowing more.
“Stand on one leg,” I instructed, and Kim obeyed.
“Hands above your head,” I ordered, and Kim did as I asked.
“Bend over.”
Kim slowly bent forward, wobbling slightly but maintaining her balance. I walked behind her, taking the opportunity to check my sister out. Her small, pert breasts, pushing against the fabric of her black tanktop. Were her nipples hard? I couldn’t tell, but I suddenly wanted to know.
I couldn’t believe my sister was doing this. Hell, I couldn’t believe *I* was doing this.
“Come closer,” I ordered.
Kim did as she was told, slowly shuffling forward on a single leg, moving forward until she was directly beside me. Her hands were still above her head, and her head hung low, eyes on the floor.
“Hands on my shoulders,” I ordered, and my sister complied.
I reached up and grabbed hold of her wrist. She didn’t resist.
“Tell me what you want,” I said softly, using my other hand to tilt her head up until she was looking into my eyes. I’ve never seen someone look so desperate, so needy.
“Master,” my sister whimpered. “Please…”
“Tell me,” I repeated.
“I want to obey,” Kim said in a whine. “Please. T-tell me what to do, and I’ll do it. I’ll do anything.”
“Anything?” I asked, letting go of her wrist and grabbing hold of her chin instead.
“Anything!” Kim cried out, her voice trembling like Mom’s did right before she left the room.
“Good girl,” I said, and my eyes widened as Kim began shaking.
It took me a moment to realize what was happening. At first, I thought it was a seizure. That the tapes – and my commands – had broken my sister’s brain.
For a moment, I thought that I’d killed her.
But then I realized: She was shivering in delight. She was cumming.
Just from being told she was a good girl, my sister was cumming.
I watched as her entire body shook, her mouth hanging open, gasping for breath as her orgasm overtook her. The smell of her arousal was strong in the air, and her eyes were glazed over, her breathing heavy.
And then she collapsed.
For the second time in a minute, I had a moment of panic, thinking I’d killed my sister. I knelt down in front of her, concerned – Kim looked up at me, her expression one of utter adoration. “Th-thank you, master,” my sister groaned, before her expression went completely blank.
The room was silent except for the hiss of the TV, and it was several moments before Kim blinked twice, looking up at me like I was a weirdo.
“What?” she asked. Her submissive tone was gone; she sounded like herself again. An expression of fear must have appeared on my face, because her brow wrinkled. “What??”
“I, uh…”
I didn’t know what to say. How do you explain to your sister that she just got hypnotized by a video tape, pledged her servitude, and came when you complimented her?
I’ll tell you how: you don’t.
“S-sorry,” I stammered. “Are you okay?”
“Yeah,” my sister replied, looking at me like I had just asked her if she liked green eggs and ham. There was a pause, and her eyes opened. “Oh!”
