Nikki's Struggle

Nikki quietly smacked herself on the forehead and mentally called her brother an idiot.

"Oh, uh, really?" said Jack. His bravado seemed to fade a bit, and Nikki sensed him trying to bury the images in his head. "Oh, shit. So you think she 'saw' what I—?"

"Yeah, probably," said Mark. "Crap. I probably shouldn't have told you that."

"No, it's okay, I won't mention it. My cousin has the same issue. Course, she just got her powers like a month ago."

"Okay, well, let's just talk about something else, before we end up pissing her off."

The conversation switched to one about how awful certain classmate's farts were. Nikki rolled her eyes. Sure, it killed Jack's arousal pretty quick, but that was too disgusting for Nikki's taste. She went into her room and proceeded to change.

A few minutes later, she was downstairs again, doing some homework on the dining room table. The boys paused their game again, and Mark proclaimed he was going to the bathroom and would "be a few minutes." Nikki shook her head, but refrained from commenting. Jack waited until he heard Mark closed the door and then got up and walked over to Nikki. Upon seeing her, his arousal sparked again, and the red glow of his attraction presented itself to her. Figuring this field test was as good as any, she concentrated on trying to block him out, and mostly succeeded, though she couldn't really concentrate on her homework while doing so.

"Hey, Nikki," said Jack, standing on the opposite side of the table. His voice was low. Nikki looked up and smiled politely at him. Jack smiled nervously. "I, uh, Mark mentioned you were having, uh, issues with your Powers, and..." He swallowed. "If you sensed something from me earlier, uh, sorry."

Nikki leaned back in her chair. "It's okay, Jack. I'm not mad. I'm actually working on the problem, so don't worry about it."

"Oh," he said. "So, uh, you're practicing stuff, I guess?" Nikki sensed his arousal jump up, and it became harder to block him out.

"Yes, Jack," she said. "So, don't worry about it. We can forget all about it."

Jack swallowed again. "Um, do you have a boyfriend?" he blurted out.

Nikki blinked at that. "Uh... no," she said. Quickly, she added, "And I'm not looking."

Jack nodded, "Okay, good, good, that's cool. I was just gunna ask—"

"Jack, really, I'm flattered, but I'm not looking," she said. "I'm not even going to consider it until I can get my Powers under control."

"Okay, well, what if I could help you with that?" said Jack.

Nikki cocked an eyebrow at him. "How do you mean?"

"You need to practice your powers, right? On a guy. My cousin's been doing it with her boyfriend. You don't have a boyfriend, you don't seem like the type to go out and get fuck buddies, and, of course, you're not going to practice on your brother. Obviously." Jack gave Nikki a smile and an almost painfully hopeful look as he asked, "Would you want to practice on me?"

Nikki let out a small sigh and put her hands up. "Okay, look, Jack, I'm very flattered that you like me, and yes, I think you're kind of cute, but I'm not ready to take on a playmate or test subject or whatever. Besides, you're still a minor."

"No, I'm not, I turned 18 last month," said Jack. "It'll be perfectly legal. Please. I like you a lot, and I want to help you out."

Nikki shook her head. "No. I can sense what your thinking and feeling, hell, I just know that look on your face. All you're really interested in is me getting you off. Plus, you want to know what Sex Powers feel like so you can brag to everyone at school that you got laid by a Sex Mage when you were only 18. I know how it is."

Jack tried again. "No, I don't— I mean— Okay, yeah, I wanna know what it feels like. Obviously. What guy my age doesn't? But I mean, this could totally work out. You get to test your powers and I get to have fun with the girl I've had a crush on since I was like 12." He gave her his best puppy dog eyes. "Do I have to say please?"

"Jack..." Nikki started to shake her head, but instead looked him over. She stopped blocking his signals out, and she could sense he was very turned on by this. His cock was semi-hard already. She took a few moments to mull it over, moments that felt to Jack like an eternity of anticipation. He was decent guy and he was cute. If he was a couple years older and she wasn't already dealing with her Power issues, she could see herself dating him. Still, he was also Mark's friend, and that might make things awkward between all of them.

Suddenly, they heard a flush as Mark finished up his business. Jack's eyes pleaded with her for a response.

"I have to think about this," said Nikki.

"Tell you what, to prove I'm serious, I won't touch myself at all until you give me an answer," said Jack. "I promise."

Nikki scowled. "Jack, a word of advice. If you want a woman to have sex with you, don't shove that kind of responsibility onto her."

Jack looked panicked slightly. "Okay, I'm sorry! Really! That's just, like, something they do now, you know, guys interested in some girls..."

"Yes, but you aren't asking me to date you," said Nikki. They heard the bathroom door open. "I'll e-mail you later. I have to think about it some more, but for right now, I'm leaning towards no."

"Good enough," said Jack in a near whisper as Mark came in to join them.

"Hitting on my sister now are you?" said Mark, with a smart-aleck grin. He hadn't heard any of the conversation, so he had no idea how right he was.

"Ha! Just getting tips on how to kick your ass even harder," said Jack, cocking a thumb back to the game. "Come on." His arousal dimmed as he focused back on the game.

"Whatever man," said Mark. Nikki watched them go and went back to her homework, though she could barely concentrate on it as she mulled the possibilities over and over in her head.

PART SIX

Two weeks had gone by since then, and Nikki had been to three more of the Sex Mage classes. She had yet to actually test her power on any of the men, but she had become better at tuning their signals out. Now, as she went through the day, she tested blocking out the men she passed on the street while trying to go about her business. She slipped up rather frequently, but she could already tell she was slowly getting better at it. However, just learning to tune the energy out wasn't really enough, and she still couldn't block out a man who was fully aroused or engaged in sex. She was beginning to think she really would need to have hands on practice manipulating the energy. Jack's proposition was starting to look somewhat tempting.

Tonight, she came home early, and sensed before she even got into the front door that Mark was up in his room, masturbating. Sighing, she concentrated on blocking him out, but then, she realized, something felt different. She paused. This wasn't the usual glow from Mark when he masturbated. The glow was stronger. The flow of energy was different. It wasn't fully contained from Mark, it seemed. She reached out with her senses and to her shock, she realized that energy was flowing into him somehow, energy from something else charging him. Now that he looked, his glow was a brilliant white, and it was burning brightly.

Nikki bolted upstairs to Mark's room. She could hear him moaning loudly, his tone almost pleading. Nikki reached out and looked into his mind and saw that he was not alone. There was a woman there in his room and she was pouring sexual magic into his system like a river. And Nikki could tell, Mark was fruitlessly trying to fight it. Nikki threw open the door.

Mark was there, completely naked, sitting in a chair. His hands were behind the backrest, and he seemed to be struggling to pull them forward. Nothing physical was holding them, but clearly, they were bound by some force. Nikki didn't need to guess where the force was coming from. She was sitting on her brother, having buried his cock in her pussy.

The girl looked up and smiled smugly. "Hey, there, sis," she said. She was fully dressed, save for the fact that she wore no panties and had her mini-skirt hiked up so she could take Mark's cock into her. Her panties had been stuffed into Mark's mouthing, muffling his cries. The girl simply sat on him, resting her head on his, and was idly typing on a smartphone.

"Who the fuck are you and what the fuck are you doing?" yelled Nikki.

"Hi, I'm that bitch, Kate, and right now, I'm roasting your dipshit brother," said the girl, giving Nikki a sneer.

"Kate? I thought you were going to leave him alone?"

"I was, till he called the fucking cops on me," she said. "I got expelled from school. My folks are furious. So, I'm gunna teach this little shitstain a lesson and roast him till his brains fry."

"Roast?" said Nikki, wide eyed. The amount of lust radiating off her brother was nearly painful for her to see. She couldn't imagine what he was feeling. Desperately, she reached out and tried to redirect some of the energy, but it was like trying to grab a burning hot firehose at full blast, one handed. The girl easily slapped away Nikki's efforts with her own Powers.

"Never roasted a guy before?" said Kate. "It's pretty fun. First you make sure he can't cum. Then you fill him to the brim with arousal. Then you make his dick super sensitive to pleasure, so sensitive one lick could make him cum so hard he black out. Though, of course, you make it so he can't black out. Then you just take his cock in you and let him 'roast' inside you. Most boys last maybe two, three minutes before they're screaming for mercy. Shitstain here's been at for, oh..." she checked her phone "...about half an hour now. I give him another fifteen minutes before he completely cracks, but just to be sure, I'll probably stick around for a few hours."

"Are you fucking crazy?" yelled Nikki. "Get the fuck off him!" She strode over to Kate and reached to grab her.

Suddenly, however, Mark's arm shot up and punched Nikki straight in the solar plexus. The blow hit like a hammer and Nikki stumbled back, gasping. "Uh, oh, looks like little bro is tired of having his big sis monopolize his cock!"

Nikki coughed and gasped trying to get her breath back. She knew Mark's punch had been Kate controlling his arm. Nikki stumbled out of the room. "You bitch," she gasped.

"Oh, don't think I'm letting you go, you fucking dyke. I know calling the cops was really your idea. I can't use my powers on you, but just you wait. I've got a couple of my boys on speed dial, wait for me around the block. All I need to do is call them over and have them go to town on you. I know your Powers aren't for shit, so it's not like you'll be able to stop them." She tapped a few buttons on her phone. "In fact, why wait? I'll call them up right now."

Nikki staggered out of the room, still wincing in pain. She went over to her parent's room and reached under their mattress. A few moments later, she was back in Mark's room, a loaded revolver pointed at Kate's head.

"Get the fuck off my brother and call off your goons," said Nikki. "I so much as hear them step onto the porch, I will blow your fucking brains out."

Kate went white as a sheet, and Nikki sensed the aura of sexual energy around them falter. Her phone fell straight from her hand. A male voice asked what was going on.

"MOVE!" yelled Nikki. Kate leaped off Mark, letting his cock pop out of her pussy. She snatched up the phone and told the boy on the other end to go home. "Now, fix my brother!" barked Nikki. Kate hastily put her hands to the side of Mark's head and concentrated. The storm of sex faded, as did the white hot glow, and Nikki could feel Mark's mind struggle back into focus. As it did, the block on his orgasm was released, and he immediately shook in a violent climax, spraying the far wall with his seed. Finally, Mark's body relaxed, and his arms went limp as Kate withdrew her power.

"Good, now get over in the corner," said Nikki. She pulled out her phone.

"I-I-I-I'm s-sorry," said Kate putting her hands up in surrender. Her lower lip trembled and tears brimmed in her eyes. "Please, I'm sorry, I got carried away! Don't call the cops! PLEASE!"

Before Nikki could retort, a fist shot out and socked Kate right across the face. Kate crumpled like a ragdoll and fell unconscious on the floor as Mark stood up stiffly, clutching his head.

"Mark?" said Nikki. "Are you alright?"

"No," he said. "No, I'm not." His hands balled into fists and he looked at Kate with murder in his eyes.

"Hey," said Nikki coming up to him and hugging him, ignoring his nudity. "Hey! Come on. Don't do something you'll regret."

"Okay," said Mark after a few minutes.

A few minutes more, and the cops were there to pick up Kate, the paramedics checking up on the siblings. Once all the questions were done, and the two given a clean bill of health, the two went to bed, exhausted. Nikki thought about the gun, now back in her parents bedroom, wondering what she would have done if they hadn't had it.

Nothing, she knew. She wouldn't have been able to do anything. If she'd had full control of her powers, she could have blocked Kate's hold over Mark, and probably fended off the boys she would have sicced on her. Or maybe not; Kate had been exceptionally powerful, after all. But at least, Nikki could have had a chance. While she didn't expect an incident like this to happen in the near future, she now knew she had to get her Powers under control.

Nikki snuck into Mark's room while he slept and grabbed his cell phone. She got Jack's number, saved it to her contacts, then sent him a text.

PART SEVEN

It took a couple days for them to arrange a get together without Mark knowing. She wasn't comfortable letting her brother know that she was going to be using Powers on her friend. Especially after the incident with Kate, she had a sense that Sex Magic was the last thing he wanted to think about. They picked a day when Mark would be away for some time, driving off to meet with some other friends in the next town over. Jack had declined to go along, saying he hadn't been feeling well.

He showed up at Nikki and Mark's place feeling very well indeed, however. He was already hard as he came up to the house. She could sense his excitement before he even reached the driveway. She pulled open the door before he could knock.

"Hey, Nikki!" he said. He was bright eyed and bushy tailed, and his cock throbbed with a bright red glow.

"Hey, Jack, come in." She wore only a short skirt and low cut tank top, simple, but more than enough to rev Jack's motor, though clearly, it didn't need to be revved.

"You look great," he said, looking her over.

Nikki smiled. "I know," she said. "You look horny."

"That obvious, huh?" he said with a laugh. "So, you want me to get naked?"

"Not just yet," said Nikki. "You want a drink? Some water, first?"

"I'm good," he said.

"Alright then. Let's go up to my room."

She led him upstairs, and he followed like an obedient puppy. She could sense his cock throbbing. She was able to read that his balls were rather swollen, and she knew intuitively that it had been a while since he had last had an orgasm. She paused at her door and turned to him. "When's the last time you masturbated?"

Jack gave her a nervous grin and opened his mouth. However, before he could say anything, she put a finger to his lips and looked into his mind. Her eyes widened slightly. "Wow," she said. "Three whole weeks?" She paused. "You really did wait for my response."

"Yeah," said Jack, softly. He kissed her fingertip, bringing his hands up to clasp hers. She withdrew her hand, however.

"You didn't have to do that."

"I know, I know, and I wasn't trying to force it on you, I just, I wanted to. If you'd said no, I would have jerked off a few days ago, but then you said yes, and, well, I figured I could wait a few more days. You know, make it special."

Nikki reached out and lightly grasped his balls through his shorts. Jack let out a sharp gasp and his body tensed; the glow around his crotch shot from red straight to yellow for a moment. She withdrew her hand and Jack sagged a bit, the colors shifting back down. "Do they hurt?"

"Y-yeah, a bit," said Jack. "It's worth it." He leaned forward a bit, getting his face intimately close to Nikki's.

Nikki put a hand to his cheek, tender, but also keeping him from leaning closer. "Jack, you're here so I can practice."

"So, practice," said Jack. He grinned and tried to step closer, intending to land a kiss on her lips. Nikki put a hand to his chest and held him back. Jack gave her a hurt look.

"This isn't going to be what you're thinking," she said. "We're not going to make out. We're not going to have actual sex. I'm just going to use my powers on you."

Jack blinked and said, "But... I mean... you need sex to make them work, right?"

"Sexual arousal is enough," said Nikki. "Right now, you're radiating enough lust, actually, that I don't even need to touch you."

Jack swallowed. "But you, you are going to touch me, right?"

"I might. But before we do anything, you need to get this through your head. We're not lovers. I'm not your girlfriend. I'm not going to be your mistress."

Jack took a step back and frowned. The glow began to dim. "I also hope you're not just going to be a cocktease."

Nikki shrugged. "You're the one who didn't jerk off for three weeks." She crossed her arms. "Take it or leave it, Jack. I don't want to be a bitch about this, but I don't want to you to get the wrong idea and think this is more than it is. So, if you really want to do this, you'll do it my way. Understand?"

Jack tried to think it over. Nikki could actually see the struggle going on between his two heads, his brain and his cock going back and forth over what to do. However, it seemed that despite the disappointment, there was some part of Jack that actually liked how Nikki was taking control. That, combined with his blue balls meant there was no real argument here. His cock won by a landslide. Nikki smiled slightly and wondered if this could be considered taking advantage. If it was, she intended to make it up to him.

"Will I, um, will I at least get to see you naked?" he said.

Nikki almost said no, but paused. "We'll see. I don't know if I'm comfortable with that yet."

Nikki could see Jack's frustration flit over his mind like an unspoken curse, but his cock quickly overruled him. "Okay," he said. "Fair enough. Sorry, if I overstepped my bounds."

"Alright," said Nikki. "Come on." She opened the door and led Jack in, telling him he could sit on the desk chair for now.

"Should I get naked, now?" he said.

Nikki smiled. "You're awfully eager to get naked."

"I figured it might inspire you a bit." Jack winked, some of his cockiness returning.

"Oh, no worries there," said Nikki with a laugh. "I know what you look like, I can get the visual from my sexual senses. Plus, you've always got quite a show going on up here." She tapped her head and grinned. "By the way, you're next line is going to be, 'well, my shorts are getting tight anyway.'"

Jack's eyes widened a bit and he gulped. "Wow," he said. "Well, heh, they are pretty tight right now."

"Go ahead if you like," said Nikki. "But remember, I'm not going to get naked."

"Not yet," said Jack as he unbuttoned his shorts.

"We'll see." Nikki watched him strip and his cock jumped out of its cloth confines, eager to be free. The glow brightened a bit as Jack fully stripped. He felt self-conscious being nude while she was still dressed, and of course, he wondered what she thought of his size. Nikki smiled. His cock was only average length, but had a bit more girth than most guys she'd seen. "It's nice. Your cock, I mean."

"Yeah?" said Jack. "Just nice?"
