"Turn it DOWN!" Philip bellowed over the thumping music.
Carrie just shrugged and stuck her tongue out.
Philip rolled his eyes and slammed the door shut on his sister. They were both college students living at home for the summer and although Carrie played the part of perfect mild-mannered daughter when their parents were home, she became intolerable when they were out.
This was one of those times.
Philip and Carrie's parents had taken two weeks off to renew their vows and after just two days Philip felt ready to toss his sister out a window.
Carrie had her friends come and go all throughout the day and night and all of them were loud, messy, and rude and Philip was always left to clean up after them.
But the rare times when Carrie actually didn't have any friends over, she would blast music as loud as she could. Philip couldn't even hope for a complaint from a neighbour due to their mom completely soundproofing the house to accommodate the band practice she had with her work friends. At least Philip didn't have any studying to do, but he wanted to at least be able to read a book or even play a video game in peace.
Philip was on his way back to his room when he stopped and looked at the pull string to the attic entrance. The place had been off-limits for so long that he had stopped thinking about it for almost a decade. His parents were usually so chill about most things it had always been strange that they had forbidden him and Carrie from going up there.
Figuring that he had nothing better to do, Philip pulled down on the string and climbed up to the place he used to wonder about so often as a kid.
Although the mystique around the attic had disappeared over the years for Philip, he was still disappointed to find that the space was completely boring. There was nothing but old boxes and lots of dust. Still, Philip didn't want to just go back down to his room and although he could still hear Carrie's music up in the attic, it was at least pleasantly muted.
Philip started looking at the old boxes and found some old college pictures of his parents. Philip flushed to see pictures of his mother decades younger. She was already a beautiful woman, but in her early twenties she looked a lot like Carrie: a free smile, wavy short auburn hair, and an absolutely giant rack. Philip felt only half guilty for checking out his mom and sister from time to time. He never full-on fantasized about them, but as a fan of huge tits, he couldn't deny that they both sported two of the best pairs he had ever seen.
Something rattled to Philip's right and he spun to face it. A box had simply fallen off of another, that was all. But the name on the box caught Philip's eye.
"Uncle Louie"
Philip froze. Uncle Louie was something of a mythical name between Philip and his sister. Technically he was their mother's uncle but that was pretty much all they knew about him. His name rarely came up and whenever either of the siblings tried to bring him up to their parents, they promptly changed the subject.
Eager to learn anything about this forbidden family member, Philip grabbed for the box and opened up. Inside was a single small amulet. It was circular and attached to a silver necklace. The pattern was a peacock with its feathers distorted into a spiral pattern. It was really quite fascinating to look at.
As annoyed as Philip was at his sister at the moment, he still felt the need to show it to her. He forgot about everything else in the attic and simply brought the amulet down and knocked on Carrie's door.
"Forget it! I'm not turning it down!" Carrie shouted over the pounding music. Philip rolled his eyes and opened the door.
"Never mind about that!" He said and rushed toward her with the amulet held out. "This was Uncle Louie's!"
Even Carrie's attention was grabbed by this news and turned to look at her brother.
"You better not be shitting me," she said and finally turned the music down so that she and her brother could talk at a reasonable volume.
"Look at it, isn't it weird? I found it in the attic," Philip said and held it out in front of her eyes.
And then the strangest thing happened. Philip swore that Carrie's eyes flashed blue for a moment. If nothing else, she was certainly staring at the amulet with a complete and utter fixation.
"See, I told you!" Philip prompted when Carrie stayed silent. He looked at his sister, waiting for her to say something, but she just stared and stared at the amulet. He looked back at the amulet and then into his sister's wide fixated eyes.
"Carrie?" He asked.
"Yes?" She finally responded. Her voice was different, however. It seemed... hollow.
"Okay, you don't have to make fun of me. I just thought you'd be interested," Philip said and started to pull the amulet away. Carrie's eyes followed it intently and just as he was about to put it into his pocket, she gasped and looked almost desperate. Philip brought it back closer to her face and she looked calm again.
"Carrie, are you okay?" He asked.
"Yes," she replied. "I am okay."
"Why are you acting so weird?" He asked.
"My... mind..." Carried said. "The... amulet..."
That wasn't very helpful, Philip thought. It wasn't really Carrie's style to pull pranks so Philip was very confused at her behaviour.
"What about the amulet?" Philip asked. He was too worried to take it away from her sight again. He had never seen his sister look so intense.
"It's... so pretty..." Carrie replied. "It's... all I can think about..."
"Oh what, so it hypnotized you?" Philip joked.
"Yes, Master," Carrie replied. Philip froze. He hated to admit it, but his cock jumped a little at those words. Philip watched a lot of hypno porn and it was a fantasy of his to have a girl roleplay it with him one day. But this? This couldn't be real.
"Lift your right hand above your head," Philip tested.
"Yes, Master," Carried replied. She immediately brought her right hand up and over her head.
"Stand up and spin around," Philip commanded. He still didn't believe it was real, but the promise of the power was too intoxicating. He needed to keep trying.
"Yes, Master," Carried replied and stood up. She spun around in a circle. Philip couldn't help but take a leering glance as his own sister's enormous breasts as she spun.
"Now look me in the eyes and tell me you love me," Philip said.
Carrie looked away from the amulet and looked right into her brother's eyes. She had looked away so easily. Was she less obsessed with the amulet now that he was giving orders?
"I love you, brother," Carrie said with a completely straight face.
"Tell me your biggest secret," Philip said.
"I cheated on my last boyfriend with my professor," Carrie said immediately.
Philip finally started to believe that maybe Carrie was truly hypnotized. Not only was she not the type to prank, but she never shared private information about herself and there was no reason for her to lie when all it did was make her look bad. It was time for Philip to take a risk.
"Do you ever catch me looking at your boobs?" He asked.
"All the time," Carrie answered simply. Philip felt a surge of embarrassment.
"And how do you feel about it?" Philip asked.
"I don't really mind," Carrie said. "Most guys look and you never look long enough to really be creepy."
"Take off your top," Philip commanded.
"Yes, Master," Carrie answered and immediately began to lift up her thin sweater over her enormous chest. Philip gawked as his sister revealed a massive green bra with plenty of creamy cleavage showing.
"Holy shit Care, those are huge! What bra size do you buy?"
"I have to order custom K cups from the internet," she replied.
"Take your bra off and suck my cock," Philip said suddenly. He would never have expected this. Even if he knew he had the power to hypnotize he never would have imagined that he would do such a perverted thing. But standing so close to - frankly - the hottest girl he knew with complete control over her mind and body, Philip gave in.
"Yes, Master," Carrie said. She reached behind her and snapped the clasp and let the hard-working material fall off her enormous tits. Then she sank to her knees on the floor of her room as Philip rushed to take his pants off.
"Shit oh shit, I can't believe this!" Philip breathed. Just as his cock sprung free, Carrie dove forward and slurped it into her mouth.
"Mmmm! Mmmm!" Carrie moaned as she bobbed her head up and down her own brother's thick long cock.
"Holy shit, Carrie, you're a good little cocksucker!" Philip praised. "I command you to love sucking my cock!"
"Yessthhppppasssthorr!" Carrie lisped with her face full of dick, ostensibly in an attempt to say 'Yes, Master'.
Carrie had already been giving a fairly enthusiastic blowjob, but at Philip's command she began to moan louder and bob her head faster. Drool flowed down his shaft and collected on his balls. Philip craned his head to get a proper look at Carrie's huge naked K cup tits swinging freely below her.
"Ohmygod, I've never had such a good blowjob! Fuck, Carrie! You're so fucking sexy! You're such a good little blowjob slut for your own brother!"
*grrrk grrrk glug glug*
Carrie impaled her pretty face on Philip's dick over and over again.
"Not only do you love sucking my cock, Carrie, but you think my cum is the best tasting thing in the world! You want it all the time!" Philip cried out greedily just as his balls started to boil.
Carrie nodded as she continued to worship Philips staff.
Then Philip exploded. His balls clenched and thick hot cum shot up through his rock-hard rod and blasted into Carrie's mouth. Carrie swallowed dutifully, gulping down every single rope of cum that Philip shot into her mouth. Philip had both never cum so hard nor had he ever had a girl swallow all of his cum.
"Woww! That was delicious!" Carrie giggled after Philip was done. She wiped her mouth and looked up at her brother with wonder in her eyes.
Philip felt absolutely amazing, but his post-nut clarity was starting to set in and he realized the gravity of what he had done. He knew he couldn't keep his sister as his sex slave all the time, both because he didn't want to take Carrie's choices away from her but also because he knew that he wouldn't be able to keep it up without somebody finding out.
"You did a great job!" Philip said. He took a deep breath and tried to keep calm. "Now, when I snap my fingers, I want you to forget that I hypnotized you. I want you to forget everything that happened while you were hypnotized, okay?"
"Yes, Master," Carrie said. She looked very serious now that she was receiving orders.
Philip paused for a moment. Although he couldn't bring himself to make his sister be nothing but a mindless hypnotized drone for him, this sort of power was difficult to set aside completely. He added one more thing:
"When I say the phrase 'Pomegranate International' I want to you return to this obedient hypnotic trance state, do you understand?" Philip asked.
