Timothy had been sprawled out on the couch watching one of his favorite anime, when he felt a sharp yank on his balls. He yelped and crashed to the floor as Sally came down the stairs, texting on her phone.
"My friends and I are gunna need to use the basement tonight," she said to her younger brother. "Turn off your weak shit, and clear out."
Timothy got awkwardly to his feet and opened his mouth to protest, but he felt her phantom hand clasp his balls, ready to give him another painful yank. He gulped, and complied, fetching the remote and turning off the TV.
"Are you, um, having a party?" he asked.
"Yes," said Sally, slipping the phone into her pocket and grabbing some fold out chairs laid against the corner. The basement was mostly finished, carpet, coffee table, entertainment center, couch and all, but was still an otherwise sparsely furnished large area. This made the siblings' house the place to go for large parties.
"Mom and Dad said—"
"They aren't here, and you aren't going to tell them shit," said Sally. She turned and glared at her little brother. "And you aren't going to interrupt, you got me?"
Timothy frowned. "Come on, I won't be a pest."
"It's not the kind of party you get to participate in," she said. She pointed to the coffee table. "Move that out of the way," she said as she started setting up the chairs to form a ring with the couch.
"But why?" said Timothy, leaning over to shove the coffee table to the side.
"Because tiny-dick losers don't get to participate in orgies," she said, matter-of-factly.
Tim froze just as he started to move the table. He looked up at her and blinked, jaw dropping. "Uh... o-orgy?" he said.
Sally nodded. "My friends and I want to have fun with our powers," she said. "Jenna just got hers last week, and we've been dying to give them a whirl in a big way. Our dumb-ass boyfriends have no idea what's coming to them."
Tim swallowed nervously, and despite everything, his cock began to grow hard. Jenna, the hottest of his sister's friends now "had her powers." And by "powers", she meant "Sex Magic." That mysterious, utterly bizarre magical ability that was spreading across the world in the last few weeks, granting women strange abilities to control men's cocks and libidos with just their thoughts.
Sally had had hers for three weeks already, and immediately had used them to bully her little brother around. She'd caught him masturbating the same day she'd gotten her abilities, to pictures of her friends no less. She'd immediately notified all her friends and used the magic to pin him down when he was in the shower, taking pictures of his naked body to post on the internet. It was only fair after all, if he was going to be lewd with her friends' pictures, then he should know what it felt like when others were lewd with his.
If that had been all there was to it, however, he might have been able to deal with it. It was true, he was a bit of a creep for jacking off to her friends pictures without their knowledge. Sally, however, had become disturbingly enraptured at the idea of how much power the Magic gave her over men, including the annoying little brother she'd never really liked. She had quickly learned how easy it was to get him to comply with her demands by attacking his balls and cock with her Magic. He'd tried to argue with her, tried to physically fight her, but all she had to do was think, and he was on the ground, writhing in pain or in that unfathomable, brain-melting level of arousal that brought men to their knees.
He couldn't even tell their parents. Every time he tried, something seemed to stop him. He had no idea why. It had to have something to do with the Magic, some kind of psychic hypnosis Sally had put on him. And right now, their parents were on a two-month long stay in Thailand, leaving their eighteen year old son and twenty year old daughter to mind the house. Even if Timothy could e-mail them about it, what could they actually do to stop a girl who could punch his nuts with a thought from the other side of the house?
The thought of all of Sally's friends coming over for a sex party and every single one of them having the Magic, though... He couldn't help it. His cock throbbed at the thought.
"Yeah, like any of my friends are gunna do anything but laugh at your little three-incher," said Sally with a snort. "Now move the table!"
Timothy blushed hotly, angry and humiliated. She wasn't wrong, though. The couple of times he'd seen Jenna or Beverly or Mary, they'd all made a point to look at his crotch and laugh. They all knew by now. And yet, it didn't seem to make them any less hot to him. In fact, it almost made them more hot!
He shoved the table off to the side, and when he turned back, Sally had set up seven of the chairs in a ring between the couch and the TV. Just what kind of orgy were they planning on having?
"Nothing you need to find out," said Sally. She pointed at him. "And don't even think about jacking off in your room while trying to imagine it." She paused, then grinned. "Oh, yeah, I almost forgot. You can't."
Timothy's blush deepened and he grit his teeth, holding back a nasty retort. She hadn't fucking forgot. He knew she was the reason he couldn't masturbate or reach orgasm the past couple weeks. Somehow, she'd found a way to block those things with her Magic. It had been a little over two weeks since his last orgasm, and his balls were beginning to ache!
"You want them to ache more?" said Sally. Timothy shook his head. "Then get the fuck out of here." Obediently, her little brother raced up to his room.
***
The girls arrived first, Jenna, Mary, Beverly, Carla, Patricia, and Joyce all piling into the living room, grinning and giddy. Like Sally, they were all dressed in short shorts and tank tops or tight short sleeve shirts.
"You brought the lipstick?" said Sally.
