I woke up far earlier than was normal. A headache developing behind my eyes, accompanying the high-pitched tinnitus in my ears. It almost felt like the kind of headache you get when you’re very dehydrated.

I sat up looking towards my window. The sun hadn’t even risen yet, I had no idea that I was even capable of waking up this early. Standing up, I got a huge headrush, needing to put my hand against the wall to keep my balance. As soon as the sensation receded, I made for the bathroom, realizing I had to go pretty bad.

After using the restroom, I went downstairs and got a glass of water and some Advil. Heading back upstairs to my room, I noticed out of the corner of my eye that my sister’s door was open ever so slightly. Memories of hearing her masturbate flashed back into my aching head. I felt an odd tug, telling me to go in there. This feeling was more than simple curiosity, it was more like a need.

Slowly opening my sister’s door in order to make no noise I peered around the corner; shocked by what I saw. There she was, completely naked, laying on her stomach limbs spread out like a starfish; well except for the one hand that was stuck deep in her pussy. Looking at her spread thighs I could see that wonderful ass that the women in my family had. Even more of note was the glistening wetness that was coating her thighs, leaving a wet spot in her bedsheets. Her head was turned away from me, I could hear the calm breaths of her sleeping.

I don’t know what possessed me to do this, but I pulled out my phone and took several photos and a video. It was only after I finished my little photography session that I realized my headache was rapidly disappearing. I had just taken that Advil, so there was no way it was that. Once again, I had a strong intrusive thought to smack her ass. I wanted so badly to do it, but I also didn’t want to incur her wrath. Upon further consideration, ever since she got that necklace stuck on her, her mood did a 180. I couldn’t tell you why I believed I would get away with it, but I decided Claire needed a little wake up call.

I reared back and swiftly brought my palm down on to my sister’s ass, causing a satisfying smack to echo off her bedroom walls. I was expecting her to shoot out of bed in shock and anger at me. Instead, her eyes shot open; unfocused and glazed over. She let out a low throaty moan. After a few seconds her eyes focused in on my face, processing that I was looking down at her naked body. She didn’t yell or cuss me out, her face went bright red, and she begun to tear up.

“Why did you do that?” Claire whimpered, burying her face into her pillow. Her fingers were still in her cunt, she didn’t seem to notice they were still in there.

“Claire… you do realize that you are laying naked, spread eagle with your fingers knuckle deep into your pussy?” I said, unintentionally using a mocking tone.

It was amusing seeing her begin to realize that what I said was true. She quickly flipped over and sat up, pulling her blanket around her.

“y-y-y-you w-weren’t supposed to see t-t-that!” Claire exclaimed with clear embarrassment.

“What was I not supposed to see?” I said, laying it on thick; intentionally teasing her.

“m-m-my p-pu… nothing!” she changed back over to the sister I knew, “Could you leave idiot, I-I need to get dressed.”

She was attempting to seem authoritative, but I could clearly tell that her mind was in disarray. She was shaking like a scared puppy; having their nose shoved into the pee stain on the carpet. I don’t know where this was coming from, but I just had this urge. I needed her to know that I was man of the house, and that I wasn’t going to let her walk all over mom or I ever again. I had already intended to confront her over her attitude towards us, but that somehow became co-opted into this new idea. I was gonna subjugate her.

“What do you need to get dressed for? It’s not like you’re going anywhere,” I said with a smirk.

“I’m going over to my friend Linda’s today, so get the fuck out of my room loser!” she asserted, yet still failing to look assertive.

“Oh, you’re not going anywhere today,” I reach over and grab the rainbow gemmed choker, slipping my fingers under to tighten my grip. As soon as I had done that, I felt an electric flow travel down my spine, through my fingers, and into my sister. She suddenly sat up rigidly and looked at me with dilated pupils. Her face flushed with red once more, but this time not entirely out of embarrassment. Claire stopped holding the blanket around her and let it slip off her shoulders, once again showing off her nude body.

“I-I'm so sorry big brother, you’re right; I won’t go anywhere!” Claire murmured demurely. Her entire demeanor changed instantly. Claire was looking into my eyes, patiently waiting for me to acknowledge her.

“Are you done with being a bitch all the time,” I hissed at her, surprising myself that I even said that, “get down on the floor and kneel in front of me.”

I did not know where these dominant thoughts were coming from, but I think I liked it. Claire slowly lowered herself down to the floor, kneeling a few feet from me.

“This is how things are gonna go around here from now on,” I began, “you are going to listen to whatever the hell I tell you to do. You’re going to start being nice to mom, and you are going to start training today!”

Claire winced at almost every syllable, it didn’t seem like I was controlling her, it seemed more like she was horny and very timid towards me; and I would never describe my sister as timid. Seeing her so drawn in and scared of my words only made me want to push her more. I leaned over until my face was right by her ear. “I heard you last night,” I whispered into her ear, “You were saying something about ‘your whore pussy needing to be punished’ or something like that.”

She looked at me with wide eyes, realizing that I heard the entire fantasy that she masturbated to last night.

“I-I don’t know what you are talking about, and why were you listening at my door anyways?” she rebuked, attempting to seem mad, when clearly, she was still scared and turned on. I pulled out my phone and showed her the pictures and video I took of her; I smirked as her face went white as a sheet.

“Why do you have those!” she exclaimed, “are you trying to b-blackmail me?” she chattered her teeth, unable to contain her nerves.

“No Claire, I'm not trying to blackmail you,” I retorted, “I am successfully blackmailing you.”

“What do you want from me then?” she whimpered.

“Claire… I already knew you were a dumb bitch, but do you really need me to keep spelling this out?” I said coldly. “From now on you will do what I tell you, there will be no more of this treating mom like dirt bullshit. Also, I'm gonna be training you from today onwards. I will ensure that that pussy of yours is properly punished from now on.

“There will no longer be any staying out several nights a week. You will have a list of chores to do every day. You will learn to treat mom and I with respect. And just maybe, if you’re a good girl, you can have a reward, but you must always be trying to be better.” I looked at her, she was no longer shaking; she sat still thinking over every word I said. I saw in her eyes the moment she went over the words ‘good girl’ and ‘reward’ in her head, she visibly shivered with excitement. I could tell that she wanted me to do this to her, but whatever sense of pride she still had was causing her to resist me. It was then that I noticed the blue gem on the choker seemed to have a faint glow to it. I knew something was up with it at this point, and I made a mental note to go back to that musty ass store and talk with the owner about this thing he sold me.

Pulling myself away from my thoughts, I focused back on Claire. I could see the conflict going on in her head over this, so I decided to make the choice for her, since she clearly needed me to make her decisions for her. I reached forward and grasped her hair, pulling her to her feet. She gasped in shock as I sat on her bed and laid her over my lap.

“This is what’s gonna happen Claire,” I said, “I'm gonna spank your ass 10 times, and you must count each one then say, ‘thank you’ right after.” I didn’t even give her a chance to respond as I reared back and smacked her ass for the second time this morning.

“OW! What the fuck is wrong with you!?” she hissed at me.

Interrupting her “Every time you do not count or thank me, the count goes back down to zero, meaning we could be here all day, and your ass will be redder than the surface of mars,” I grinned. Again, I smacked her asscheek and heard he let out a yelp.

“o-o-one, t-t-t-thank you,” she muttered, clearly holding back tears.

SMACK

“t-t-t-two… thank yoUUU,” her voice rose at the end as I quickly smacked her a third time.

“p-p-please no more, big brother. I promise to listen to you from now on,” Claire whimpered.

“I already know you’re gonna listen to me, this punishment is necessary for you to learn how to behave. Speaking of,” I chimed.

SMACK

“The count starts over Lil’ sis. Back to one,” I whispered in her ear.

SMACK

One, thank you…

SMACK

Two, thank you

This went on for a bit; she had to restart a few times, and as soon as we were nearing the end, she began to squirm and let out little moans every time I smacked her tight ass. On the 8th spank I left my hand on her cheek, and slowly slid it to her pussy. I wasn’t too surprised to find that she was soaking wet.

“Is my little slutty sister gonna cum from having her ass spanked?” I muttered into her ear with a clear sound of disgust.

“No, you’re l-l-lying, I hate this! This doesn’t feel good at all,” she squeaked out, clearly unable to hide her arousal.

SMACK

“n-nine, thank you!” Claire sighed out, attempting to hold back a moan.

“Are you ready to cum from getting spanked by your big brother,” I asked her, a large grin on my face.

“S-stop saying that, there is no way that’s ever gonna happen!”

“If you say so” I replied once again raising my hand, preparing to give her the hardest spank yet.

SMACK!!

Claire desperately tried to resist her orgasm, but alas her need to cum won over. Her eyes rolled into the back of her head as her body tensed up over my lap. She made little noise other than the strained gasps and sighs that she held on to. Her pussy while not fully squirting, dripped on to the floor. The room exploded with the smell of her nectar; it was wonderful.

As soon as she calmed down, I looked at her, seeing that she was passed out from the intense paingasm I gave her. A twisted grin spread on my face as I contemplated the many things we would do as I trained her to be a good little sister.

I didn’t know how long I was out for. Zach had woken me up with a smack to the ass when it was still mostly dark out. He then threatened blackmail against me, proceeding to spank my ass until I had a massive orgasm. I must have passed out from it, I was still naked, but now I was under the covers in my bed. There was light coming in from my window which meant I must have been out for at least an hour. Mom most likely already left to go work her dumbass job. Shifting my head to look over at my door which was now closed, I was alone in my room. When I moved my head I felt the bejeweled choker on my neck, I ran my finger over the thin chains, counting each of the gems by touch.

I thought about last night, and I could feel my face heating up with shame and embarrassment. Why did I do that? I have never fantasized about my brother. Other than the shame I felt at what I did, I also felt that heat radiating from my core. Over and over my mind went back to my brother spanking me. It really hurt in the beginning, but after a bit the heat emanating from my asscheeks started to make the spanking feel good. I had to try so hard not moan and grind my pussy against my brother’s lap.

Ever since I put on this necklace – which I still was unable to get off – for some reason I get so aroused around my brother, and when he talks down to me, I feel so small. My pussy got so wet last night thinking about my brother fucking me, and cumming in me. My hand snaked down my body and started lightly rub against my folds. My breathing quickened, imagining my brother’s big cock. I closed my eyes and began to rub more vigorously over my labia. Once my clit popped out, I started to pinch and rub my fingers against it, sending electric jolts of pleasure through my body. I was totally unaware of my surroundings. Unsure of the wanton sounds of pleasure I was making. I plunged two of my fingers into my cunt, using my palm to frig my clit. The noises my wet cunt was making were only making me hotter. My orgasm was building up quickly, I was so close to the edge.

I heard my bedroom door open. My eyes shot open to see my brother looking at me with smirk; the look only aiding in soaking my bedsheets with more pussy cream.

“you’re not allowed to cum until I say you can,” he said matter-of-factly.

Right as I was about to plunge over the edge into an orgasm, I suddenly felt like I was unable to get there. Fingering myself while my brother watched was still getting me off, but I was now unable to orgasm. This scared me greatly. How could he control my own bodily functions like that.

My brother pulled up a chair and watched me. He pulled of the blanket so he could observe me closely. I just couldn’t stop fucking myself with my fingers no matter how embarrassing this got. His eyes were full of hunger as he watched my fingers sloppily go in and out of my cunt, making wet noises. Minutes went by and it almost felt like I was gonna have a panic attack due to being unable to cum; having no option but to keep going while he watched. I began to feel delirious with need. I wanted my brother’s cock so fucking bad. I began to raise my hips up and shake them, hoping he would get the hint that I wanted him. I could never tell him out loud how much I wanted this, but he said that I needed his permission to cum; could I really do that? Would that even work?

“Big brother?” I exclaimed breathlessly.

“What is it my slutty little sister?” he responded, amusement on his face.

“I need… I have to c-c-cum!” I finally got out.

“Well, I won’t give you any permission unless you beg for it like the little whore sister you are,” he said with a dispassionate tone, yet I could still hear that animalistic hunger in his voice.

I couldn’t do it. How could he possibly ask me to beg for him. As the seconds went by though, I started to consider it a little more. Maybe if I just ask him nicely, he will say I can. Upon further consideration I knew he wouldn’t do that. He knew that I knew what I had to say.

“Please?” I whimpered softly.

“Please what, slut?”

“Can I please cum?”

“You know the words I want to hear,” the intensity in his eyes driving me crazy.

I couldn’t do it any longer, I needed to cum so fucking badly. I thought I was going to lose my mind with how much need radiated from my body. The idea of begging him started to seem appealing. Maybe it wouldn’t be so bad to have him fuck. Then I could be his good girl. The thought alone would make me cum if it wasn’t for his order.

“p-please big brother,” he looked at me with a raised eyebrow, “I’ll do whatever you ask of me. I want your hard cock in my little pussy so bad… fuck, I could cum on your cock for days, it would feel so good,” I was beginning to lose control over my train of thought, “please, please, please, please big brother I need to cum so bad, please watch as I soak my bedsheets with my cream. I need you to see how much my holes need you in them.”

“Alright I'm gonna count down from three, and when I hit zero, I want you to cum harder than you have ever came before,” he said with that hot smirk of his.

“3…2…1…”

He delayed hitting zero, and I could feel the enormous pressure building up to its peak with nowhere to go. I was starting to black out from the overload of sensations.

“zero”

Existence before me ceased to exist. I was floating in a white void. Rays of light bathed my body in the most exquisite pleasure I have ever experienced in my life. I never wanted to leave this place. I would do anything to come back here again. While that was happening in my head, my body was not the image of serenity that I imagined. My back was full arched, thrusting my cunt high up into the air. My eyes were so far in the back of my head I could read my own thoughts. Another first for me was I squirted. I had never squirted; like many people I thought it was just a myth, and that these so called squirters were just peeing. I was a believer now, and I would have it no other way. My squirt hit the wall at the end of my room. My brother was jubilant seeing my whore pussy get my room all sticky with my slick. I apparently was also screaming moaning; usually I was a silent orgasmer, but this was clearly a whole new level of bliss.

As my consciousness came back to me, I was in such a blissful state of afterglow that the condescending looks my brother gave me weren’t bothering me in the least; if anything, it just got me hot again.

“Go get yourself washed, you stink like sex,” my brother said while throwing a towel at me and walking out of my room. The shame started to creep back in as I thought back to what I said to get his permission. With that shame was a much stronger ravenous need for him to use me. It felt like I finally had a purpose; to be his fuckslave. Just thinking about it made me want to finger-fuck myself again so badly. Maybe I can do it in the shower.

I couldn’t believe I just did all of that. I sat that there and forced Claire to beg me for an orgasm. I was never this assertive. For that matter, I have never seen my sister so submissive. I needed to head back to that store and ask that old man what the hell is going on.

Getting dressed I headed downstairs. I just needed my keys then I could drive over to the mall. Turning the corner into the kitchen I almost ran into Claire, who was wearing a loose crop top and daisy duke jean shorts. Her midriff laid bare. While she might have exercised when she could, her laziness also made her stomach appear softer than taught. I stood more than half a foot taller than her, seeing her look up at me with those doe eyes.

“Are you going somewhere?” she mumbled.

Again, I felt that need to make her submit to me, and she clearly saw the emotion flash on my face as her eyes widened, and she backed up a bit, shrinking into herself.

“Yeah, I just need to take care of some things, I shouldn’t be gone that long.”

“Oh… umm okay,” she said looking down at the ground, “is there anything you need me to do? Since you said I would have daily chores from now on.”

I had almost forgotten that part. Was she secretly eager to follow my orders? The corner of my mouth drew up into a slight smirk; Claire understood right away I was going to do something to her.

“Do you own a vibrator?” I asked.

“Umm… yeah, maybe a few,” she replied skittishly.

“Ok I want you to clean the kitchen and living room while I'm gone,” pausing for a moment to have her hang on my words, “while also having a vibrator in your pussy the whole time. While I am gone you will keep it on, and you will not be allowed to touch yourself other than to ensure the vibrator doesn’t fall out. Lastly you are not allowed to cum until I come back home and evaluate your work. This time I'm not gonna prevent you from cumming, so this time you’re really gonna have to focus on holding it back. And if you lie to me, I will know, and you will be punished.”

Claire visibly shuddered at the word punishment. I told her to go upstairs and grab her biggest vibrator and bring it to me. When she returned, she had a modest sized 6” pink vibrator – nothing too fancy – I took it from her and told her to bend over the couch. She was frozen there unable to process my command, her face bright red. Again, I told her to bend over or else she would receive more spankings. This got her to move, although with trepidation. Pulling down her shorts and panties I saw my sister’s bald pussy, and she was dripping wet, her sex radiating heat from pure arousal.

“you’re acting so timid, like you hate this,” I condescended, “but your body doesn’t lie. Your slutty little pussy is so excited to be filled by your vibrator, or maybe it wants something else to fill it.” My sister tensed, shuttering with unsaid need. I took the vibrator and rubbed it along her folds, ensuring it was properly lubed up by her slick. She lets out quiet sighs, trying not to show me she was enjoying it. I teased her with the vibe for a little bit longer before I pulled back and turned on the vibrator. My sister flinched at the suddenness of the sound, expecting me to further tease her. I wanted to keep her guessing, so instead I stuck the vibrator up her cunt all in one go with almost no resistance. She moaned loudly from the surprise, placing her hand over her mouth to stifle further moans.

“Put your shorts back on and get started on your chores slut,” I whispered hotly in her ear. She stood up slowly, not trying to move to quickly to avoid the vibe rubbing her insides. Her face was burning red, her eyes were dilated, and she kept twitching imperceptibly.

“Have fun my slutty little sister,” I snickered. Leaving the house, I turned around before closing the door to see her standing there with her thighs pressed together, while looking at me like a lost puppy. Shutting the door, I made my way to my car and headed back to that weird store.

Walking through the mall for the second day in a row, I was honestly expecting the cliché of the mysterious store to suddenly be gone the next time I went by. Surprisingly, it was still there, and just as empty as I last saw it.

I walked towards the back and rang the service bell that was on the glass display case.

“you’re back,” I heard the old man say from behind me. Turning around I saw he was kneeling by one of the shelves, organizing the junk to look less like junk.

“What the hell is up with that necklace?” I asked, getting straight to the point. I wanted answers right away, my patience growing thinner by the second.

“Did someone put it on?” the old man asked. He seemed excited at the idea. He stood up and stretched out his back, popping several times. Heading back behind the counter, he leaned over and picked up and old leather-bound book. Turning the pages until he came to a picture of the very necklace itself. The book was in a different language; one I had never seen before.

“The Prismium; as you heard me call it yesterday, is an object of considerable power,” he said while looking at the book, “When it is placed on someone it shall remain on them until the next new moon. Our last new moon was 4 nights ago, so you have a bit of time before you can remove it; same with the ring of course. May I ask who wears it currently?”

“My sister was poking around in my room and put it on without my knowledge.” I responded.

“Well then that means she is bound to you until you can remove the necklace.”

“What does that even mean?” I asked incredulously.

“It means she is yours,” the old man paused for effect, “each of these gemstones corresponds to a personality change, the default being the blue gem of submission,” he continued, “there will even be some physical changes as well that you may appreciate, both for your sister and you.”

“that’s sounds like a bunch of crap,” I griped, “All morning I have been so out of sorts; being aggressive and demeaning to her. I am normally not that person.”

“The necklace is merely allowing you to release your pent-up urges. The ring is the connection point between you and your bound one,” the old man noted, “now that you know of its effect on you, you should be able to better control these mood swings. It will even affect people around you depending on how you want your collared one to be perceived.” Chuckling to himself, the old man began to write something down on a piece of paper. I pinched the bridge of my nose and let out a deep sigh of frustration. “Fine, if I can’t remove the necklace, or ring until the next new moon then I might as well know how it works.”

“It’s simple really, just touch the necklace and think of which gemstone you want to be active,” he added, “this is a list of what each gemstone does. And I have included some of the ring’s abilities too, but I don’t want to spoil too much of the fun.” The old man grinned while handing me the piece of paper. “Oh, and one more thing,” the old man remembered, “The ring’s power will get stronger the longer both the necklace and ring are worn, but I'm sure you’ll figure it out in the end,” the old man gave a creepy smile.

Not wanting to spend another second in that store I turned around and made my way out. Getting in my car I took that paper out and skimmed it quickly. There were quite a few unbelievable sounding abilities, I wished I could say this is all fake, but the way my sister changed really convinced me of the collars magic. Putting the list back in my pocket, I started my car and started making my way home. As I was driving up the highway, I felt this sudden pull to my vision. Following this pull I saw a sign for a sex shop. Without even considering it I pulled into the parking lot and got out of my car, heading to the door.
