Twins

As I wandered alone throughout the halls, I saw plenty of girls who might be great targets, but none that satisfied my lust at the moment. Most of the girls at my school were surprisingly unattractive, despite the few exceptions here and there, and they were either already taken or didn't date. It's not like that was a problem now that I had the rule book, though. The idea of breaking up a few couples by making the hottest girls in school fuck themselves on my cock while their boyfriends were **** to watch was one I didn't hate. It was all about finding the right girl for the moment, though...

...or rather, girls. Just as I rounded a corner, I spotted Tabitha and Callie Brenner, two brunette twins that would lend themselves to some creative rules for the rule book. Callie was the more sporty of the two, currently wearing a plain black skirt and sports bra, while Tabitha, who was the more nerdy between the two, sported a sweater that cut off just below her cleavage, her typical rounded glasses, and a plaid skirt. Both had their hair tied up in ponytails, which seemed somewhat fitting for what I had planned. I visibly nodded with certainty. They were to be my next pick.

"Um, Michael, what are you doing out of class? Lunch ended a few minutes ago," Callie chirped.

"Oh, I was simply coming to find you, in fact. I have something that you both might enjoy."

"Really? And just what might that be?" Asked Tabitha inquisitively. I quickly pulled out the rule book and began to write.

New Rule: Tabitha Brenner will now feel every single sensation that Callie Brenner feels, and Callie Brenner will now feel every single sensation that Tabitha Brenner feels. However, they are not allowed to cum unless both of them are given verbal permission by the user of the rule book.

As soon as I finished with the period, the effect was instantly visible. Callie practically jumped at suddenly feeling her sister's warm sweater draped around her arms, while Tabitha felt the tightness of Callie's sports bra. They began pinching and clutching at themselves, trying to discover how and why their sensations were intertwined. I decided to stop their exploration and have some fun.

"Alright. Now that you are feeling the effects of my little gift, it's time to use it. Callie, get undressed and begin masturbating." Instantly, the sports bra and skirt came off, and her fingers plunged directly into her pussy. While Callie managed to control her moans, Tabitha was not so quiet.

"Oh...Oh my god...Callie, keep going...Fuck meee..." I smirked at that. "Gladly. Tabitha, kneel down and fuck your face on my cock."

The nerdy brunette quickly shot down to crotch-level, unzipped my pants, and began gagging herself on my penis. Soon, Tabitha's nude counterpart began gagging as she felt an invisible dick burrowing itself into her throat. Her mouth hung dumbly open, and drool began quickly leaking as her lips formed a crude rendition of an "O" around a cock she wasn't touching. Surprisingly, Tabitha seemed quite adept at dick sucking, as she involved her tongue in ways I didn't expect for someone so stereotypically nerdy.

After some time, I picked up on the fact that Tabitha and Callie were hanging just on the edge of an orgasm, and neither could figure out why they couldn't cum. I smirked, looking into Callie's **** eyes as she needily fucked her cunt with her sopping wet fingers.

"Would you girls like to cum?" Callie nodded rapidly, as if I just offered a starving person a loaf of bread, while Tabitha moaned in rapid succession, as if trying to scream out "Yes! Yes!" I pinched my fingers over Tabitha's nose, and restricted her air completely. I stopped slamming my dick into Tabitha's throat, and simply let her **** on the lack of air. Soon, Callie was gagging and grasping at her throat with her free hand too.

"If you girls want to cum, you need to beg to become my slaves. Callie, seeing as you're the only one with a mouth free, beg for your sister's enslavement." Callie, with eyes pleading and hungry for air, locked with mine, hoping I'd find some mercy in her situation. She saw no mercy in me. I wanted them both to throw away their person-hood for me or risk ****. After seeing no escape, Callie began to **** out words, despite herself and her sister thrashing against nothing and myself respectively, **** for air.

"Plee...Please...Ack--Agh...Please use my sister...Fuck her everyday...Make her your--Ock...Ack...****..." That was good enough for me. I let Tabitha back off of my cock for but a moment, allowing her a single breath of air. I then plunged back into her, and Callie groaned in frustration.

I simply lowered my head, eyes staring ahead at Callie. "More."

"My sister is not human...She is property for you to use. Use her if you please...her holes are yours. Her mind is yours. Her body is yours. She deserves nothing more than to serve you...because it is...ack...it is a privilege that you let her serve you..." I smiled.

"Good. You may both cum." Instantly, their bodies thrashed about with pleasure, squirming in their respective places. While Tabitha slumped against me and quivered in bliss, Callie seemed to have a small seizure, tossing herself about on the ground with orgasmic joy. I pulled out of Tabitha's throat, and let the pair breathe. They panted furiously as air filled their lungs, and Tabitha began crying with relief. I, however, would not let them get a moment of rest.

"Tabitha," Her eyes looked up to me from the floor of the hallway, breathing heavily, her eyes still wet with tears. "Be honest with your answer. Do you wish to become my ****?" She was quiet for a long time. She seemed as if the answer was more complicated than a yes or no, as if some asterisk in her mind made her pause and mull over her true feelings.

After a moment of silence, she answered, "No." I frowned. This is not the answer I wanted. Although I should go back to class, I absolutely should find a way to discipline these two. And besides, I still hadn't blown my load yet, and staring at Callie's nude body gave me a few ideas...
