Title: Incest Quest (An ADMIN Tale)

Categories: BD, DS, EX, FT, IN, MA, MC, MD, MF

Preface: This is principally a tale of a brother who lusts for his sister and wins her heart, so it’s a bit of a romance in a taboo kind of way. It’s also a tale of a kind of mind control, albeit of a rather weak and incremental nature. Ergo, it is something of a slow burn. This chapter does not have any sex, although it features some hopefully sexy shenanigans to enjoy as an appetizer. The main characters also have some scent-based fetishes, by which I mean a lot of sniffing of underwear and the like, and an interest in sweat, but nothing with... digestive odors, so to speak. There’s also frequent focus on sex fluids, female body hair, and public exposure. Later chapters include some light BDSM, petplay, and pregnancy-related fetishes. The FAQ below is included as a reference and is not strictly needed to understand the story, so you can skip directly to Chapter One if you like, but knowing what the character is referring to when he thinks about the information in the FAQ is probably helpful.

Congratulations on being selected for the beta testing of ADMIN — the Application for Direct Messaging Into the Neocortex! With this app you will be able to affect the higher-order brain functions of your subjects, including sensory perception, cognition, generation of motor commands, and more! With patience and cleverness, you can convince your crush that you are the epitome of their desires, compel people to complete tedious chores on your behalf, even turn your worst enemy into your loyal pet, if that’s what floats your boat! The main limitation is your own imagination!

FAQ

How Do I Get Started? The ADMIN system can import your contacts from most devices and other applications. Our SEE system (Search Everyone Everywhere) also allows you to find people by uploading a photo of your intended subject; as long as you know their name, you can add them to your list! Once you’ve found your intended subject you can start messaging, but watch the power level on your device! Some of the changes possible with ADMIN can drain your batteries quickly.

What Kind of Messages Can I Send? There are four main categories of messages available in ADMIN beta: senses, thoughts, behaviors, and actions. By selecting a category, you can type out a command for the integrated AI to interpret, which will then be sent directly into the subject’s brain. Want the subject to think your cum tastes like chocolate? Want them to get a spike of arousal when they see you? Want them to moan with delight at your touch? Want them to drop to their knees and open their mouth? All of that and much more is possible with ADMIN!

Can Subjects Ignore or Resist the Messages? The messages cannot be ignored, though most subjects will have some degree of resistance to messages that represent a drastic departure from their normal experience. But with patience, you can lead your subject step-by-small-step almost anywhere you want them to go! The ADMIN system will calculate the percent chance of success for any message entered, allowing you to confirm or cancel if you don’t like the odds! In most cases, success with one command will make subsequent similar commands more likely to succeed, allowing you to escalate until the subject is right where you want them!

Can I Test a Subject’s Resistance in Other Ways? Absolutely! With our SCORE system (Subject Condition: Obedience, Resistance, and Environment) you can calculate the probabilities of a variety of hypothetical scenarios. Want to find out how likely it is that a command to start stripping will be acted upon, based on where the subject is or what it is doing at the time? You can!

Can I Boost the Power to Overcome Resistance? You betcha! Beta testers get ten tokens per day and each token can be used to increase the likelihood of success for any order by up to 5% (at this time, no order can be greater than 99% likely to be accepted). Tokens can also be spent to reduce the power requirements for a given order, giving you longer battery life for your device or helping you squeeze one more command out before you have to recharge!

Can I Buy or Earn More Tokens? ADMIN beta does not allow the purchase of tokens, we’re sorry to say, but it is a planned feature for the upcoming full release! But happily, you can earn tokens by helping us test the features! By accepting and completing challenge quests, you can earn extra tokens every time you reach a new stage of accomplishment!

What Kind of Challenge Quests Are There? Oh, there’s lots, don’t worry about finding one that scratches your itch! Some examples include: turn a shy person into an exhibitionist; convince family members to have sex with each other; convert someone’s sexual turn-off into an obsessive fetish. You can even submit requests for personalized quests to the development team!

What’s the Catch? The only catch is that anyone selected to be a beta tester was chosen because they aren’t likely to resist the urge to run amok and completely wreck their lives and the lives of those around them! Have fun!

Chapter One (Monday Morning)

Aaron laid in his bed and frowned at the FAQ for the new app that had inexplicably appeared on his phone sometime in the night. He certainly hadn’t downloaded anything like this, so he assumed it was spyware or malware of some kind. Still, there wasn’t really much to risk if it was, as his bank account was almost empty and it had probably already spammed itself to everyone in his contacts if it was that kind of program. Aaron went ahead and clicked on the icon to open the app and see what it was actually about.

Just as the FAQ implied, there was a button labeled SEE next to a text field for SUBJECT, and beneath them was a grayed-out button called SCORE and four buttons with image icons of an eye, a brain, a foot, and a hand, which presumably stood for perceptions, thoughts, behaviors, and actions. He tapped on the subject field, which first prompted him to import contacts; accepting that, Aaron typed in his own name, which caused an alert to pop up.

WARNING: User has self-selected as subject. Certain commands may cause irreversible feedback loops or doom spirals. Do you wish to proceed?

“What the hell kind of warning is that?” he chuckled, confirming the selection. Staring at the ceiling for a moment as he contemplated what to type as a command he finally selected the action button, which opened up a new dialog for text input. Grinning, he typed in ‘jack off until cumming,’ which he had been thinking about doing to relieve his morning wood anyway. After submitting the text, a little icon of a clock appeared along with the word ‘calculating,’ but they vanished after a few seconds and the app displayed:

95% chance of success, 3% battery power. Confirm? Cancel?

Aaron went ahead and tapped confirm, which caused the dialog to close. He immediately put aside his phone, pulled down his boxers, and started jacking himself off, to his great bewilderment. He tried in several ways to stop himself, but the best he could do was force himself to switch which hand he had on his dick. He felt both worried and elated as he started seriously considering the possibility that the app was somehow real.

As he got closer and closer to his climax he couldn’t help but start fantasizing about what this might allow him to accomplish. There were several girls at the community college he attended that he found attractive, and while none of them had been mean about his clumsy efforts to befriend them, not one had acted more than politely aloof toward him. And the FAQ had said something about an incest quest. One of Aaron’s secret shames was how attractive he found his 18-year-old sister, currently a senior in high school, as well as a couple of his cousins who were a few years older. Imagining all three of his relatives happily having sex with him and each other triggered his release and he spewed an unusually large amount of cum all over his hand, boxers, and blanket.

Finally released from the compulsion to masturbate, Aaron tried to clean himself up a little and then grabbed his phone to look more closely at the ADMIN app. He found a settings control which allowed most of the usual features for account name, passwords, and the like. One unusual feature there was awareness; upon tapping it he saw a toggle that was currently set to ‘off,’ along with an explanation.

When awareness is off, targets will rationalize any commands they receive as being their own idea or the result of an accident, etc. Individual subjects can have their awareness adjusted without changing the global setting. The user cannot toggle their own awareness off.

Aaron grunted and proceeded to password protect the app, in the unlikely event that anyone happened to pick up his phone and find it. He then went back to the main menu and found two more buttons at the bottom of the screen he had overlooked earlier. One was a T inside a circle and the other looked like the silhouette of a flag waving in the wind. The first button turned out to be tokens, as he had expected, and he indeed had ten of them at his disposal. The flag icon was the quest list.

Aaron looked at the ceiling again, pondering what quest he should pursue, or if he should just perform some random experiments first. He quickly decided that if he was going to pursue any impossible dreams he may as well aim as high as he could. Poking around on the quest menu he soon found a section for Incest Quests. Tapping on it brought up a dialog box with more details.

So, you’re looking to keep it in the family, eh? We don’t judge! The closer the relation, the bigger the token value! Our handy leveling system will help you learn the ropes of the system to turn a sibling, parent, or other relative into a sex partner! The leveling system also follows branching pathways to help you mold the family member in just the right ways! Continue? Go Back?

Aaron tapped on ‘continue’ and was prompted to enter a subject name, which included a dropdown menu that listed his immediate family followed by more distant relations; apparently the app was able to determine relationships somehow. He quickly selected his sister Jessica, whose name was at the top of the menu. The ‘calculating’ image appeared again for a few seconds before the app gave him another chance to confirm or go back.

Jessica O’Neill, Age 18.09. Base Rating/Incest Fetish: 4%. Challenge Rating: Hard. Total Available Tokens: 600. Proceed to leveling menu?

Aaron was a little intrigued that his sister apparently had any interest in incest whatsoever, as she gave the impression of being very demure and well-behaved. Still, it was hard to guess what exactly a 4% rating meant in the real world. Did she maybe have a sex dream about a family member once in a while, or idly appreciate her brother’s butt occasionally? There was no way to tell, currently.

The leveling menu showed that there were twelve steps on the quest to twist his sister into his sex buddy.

  1. Fantasizing
  2. Flirting
  3. Kissing
  4. Groping
  5. Partial Nudity
  6. Full Nudity
  7. Sexual Touching
  8. Oral Sex
  9. Intercourse (Vaginal or Anal)
  10. Fetish Sex 1
  11. Fetish Sex 2
  12. Fetish Sex 3

It seemed like a relatively normal relationship progression to Aaron, although he clicked on ‘Fetish Sex 1’ to make sure he had the right idea. The dialog more or less confirmed his suspicions, in that the user could select from a number of kinks to aim for, rather than having to move to group sex or something else they didn’t enjoy in order to complete the quest. As it happened, he could select from a large list but had the option of changing them at any point prior to starting the level.

Aaron pondered what he should choose, but tabled the issue of his target fetishes for the time being and confirmed the quest. A short fanfare played and the app displayed, “THE QUEST BEGINS!” It then flashed a picture of Jessica on his screen, one which he didn’t recognize; perhaps it had pulled the image from one of her social media accounts? A prompt that read ‘LEVEL ONE’ appeared over the picture, leading to another dialog box.

The first step on your quest is to make your sister want you enough to respond to your advances, or else advance on you! It’ll be tricky, but we have faith in you! Try starting out with sensory adjustments and incremental thoughts to build toward actions and behavioral changes. Or you can try to make her flick her bean while looking at your picture straightaway, if you think that’ll work better! Good luck!

Aaron smirked, pretty certain that the second suggestion was meant to be sarcastic. Still, he figured he should use that SCORE system to run a few scenarios and get a better idea of what his options were. He pulled up the menu and asked it to calculate the odds on ‘picture brother Aaron naked.’ The AI pondered for a few seconds.

2% chance of success, 2% battery power. Execute order?

Aaron frowned. If he was interpreting things correctly, his sister couldn’t avoid picturing him naked if he told her to, but there was a very low chance that she would enjoy the mental image. He supposed he could just keep spamming her mind with dick pics to see if she got blasé about it, but that seemed unsubtle, uncertain, and too draining of his battery for possibly very little benefit. He tried changing the command to ‘watch Aaron’s butt whenever possible’ and recalculated.

6% chance of success, 2% battery power. Execute order?

Aaron’s lips twisted, slightly frustrated. This was an improvement, but not much of one. He switched over to the sense perception tab to see if it had better odds of success. After thinking for a moment, he tried ‘seeing Aaron gives you a sexy thrill.’ He was disappointed to find that the results represented only another marginal improvement.

12% chance of success, 2% battery power. Execute order?

On a whim, he altered the word ‘seeing’ to ‘smelling.’ His sister had about fifty different kinds of bath products of various scents and fragrances that took up a whole shelf of the bathroom cabinet, not to mention all of the various perfumes and body sprays she kept in her room. Maybe that was the way to crack her?

74% chance of success, 2% battery power. Execute order?

“Hot damn, I was right!” thought Aaron with exultation. He immediately confirmed the execution and waited to see what happened. It took about twenty seconds and he was fidgeting with impatience before a dialog appeared.

Triumph! Target’s olfactory memory of subject Aaron O’Neill has been successfully remapped to the pleasure centers of the target’s brain. Level One tokens earned: 5/50.

That reminded Aaron that he could use tokens to increase the odds of success. With 15 tokens available now, if they all gave him a 5% boost he could make his original command idea almost certain to succeed! With excitement, he went back to the order to make her imagine him naked and dumped all his tokens into the command. He was devastated to see that in this case they only added 1% each, bringing the odds up to a dismal 17%. Apparently orders with very low chances of success were hard to boost. Still, with enough tokens…

Aaron suddenly got an idea and leapt out of bed to take a shower. He deliberately left his clothes on the bathroom floor, a bad habit that his sister often complained about and would therefore not seem suspicious. He would ordinarily be embarrassed about the obvious cum stains on these and remember to hide them in the hamper or rinse them off, but today he left them proudly sitting atop the small pile of his other night clothes. Sure enough, almost as soon as he jumped in his sister was knocking on the door asking how long he would be and warning him not to use up all the hot water. Aaron grinned at her predictability; he figured it was probably a passive aggressive means of paying him back for the various ways he annoyed her, but today he was thrilled about it.

Quickly finishing the shower, Aaron grabbed his phone and toggled over to actions, entering ‘sniff Aaron’s boxers when you find them.’ The calculated success rate in this case was 33%, which excited him greatly, but he dumped all his tokens into the effort and saw that they netted him a 4% increase each, bringing the odds all the way up to 93%. His heart beating wildly, he confirmed the order and waited.

Triumph! Target will now sniff subject Aaron O’Neill’s boxers when she finds them. This action may recur several times if opportunities are available. Level One tokens earned: 10/50.

Aaron pumped his fist in the air and tried to avoid yelling with glee. He wrapped a towel around himself and walked back toward his room shouting, “Bathroom’s all yours, Jess!” Once inside his room he quickly dressed while listening for the sound of his sister leaving her room.

A few minutes later he heard her enter the bathroom so he crept out as quietly as he could to listen outside the door. He heard his sister exclaim, “Yuck!” when she first noticed the pile of his clothes, perhaps even realizing they were jizz-stained. Aaron held his breath in anticipation, then heard his sister take a deep breath and let out a quiet moan.

Flushed with his early victory, Aaron crept back to his room to deal with the painfully erect boner he had suddenly developed. He felt that his quest to fuck his sister was off to a great start. His dick was painfully hard so he released it from its confinement and stroked it a bit, but decided to try to twist Jess a little more before he got himself off.

The app had implied that incremental orders would tend to get easier because of earlier successes, so he decided to try expanding on Jessica’s scent-based desires. In the behavior tab for his sister he wrote ‘will steal Aaron’s dirty boxers to hide under pillow.’ The initial chance of success for the behavior was 41%. Aaron debated on whether or not to use his five tokens to try to boost the odds but decided to save them for now; at best they would give him a 66% chance. He executed the order with its base values.

Failure! The target has successfully resisted the attempt to change her pattern of behavior.

Aaron groaned in disappointment but then remembered that the app drew a distinction between behavior and actions. He supposed, based on the failure message, that it meant behavior referred to a person’s habitual actions, whereas the action command was targeted at one action or type of action specifically; the earlier success dialog had implied that Jessica might sniff his boxers several times before the command wore off. He tabbed over to the action button and repeated the same command, pleased to see that the odds of success had increased to 59%. He wondered if that meant his sister was naturally slightly more inclined to steal his cum-stained underwear than leave them in the bathroom.

The tokens added 5% each to his chances for this command so he went ahead and boosted the odds to 84% and executed it. He waited, breath held, while the app performed whatever science or magic it used.

Triumph! The target will steal subject Aaron O’Neill’s dirty boxers to hide under her pillow. Level One tokens earned: 15/50.

Aaron immediately threw himself on his bed and jacked his dick furiously while listening for the shower to end. He reached his climax well before his sister finished her morning rituals, which he supposed wasn’t too shocking. Eventually the water turned off and he waited very impatiently for her to leave the bathroom, but it was a good twenty minutes before she finished her after-shower routines. As soon as her door shut Aaron dashed into the bathroom to check the hamper. Sure enough, his shorts and shirt had been tossed in but his boxers were nowhere to be seen. “Success!” he yelled in his mind.

* * *

Jessica grimaced in disgust when she noticed another pile of her brother’s dirty laundry on the bathroom floor. “God, he is such a disgusting slob!” she muttered under her breath. Not wanting to step on the things, she reluctantly bent down to pick them up, pinching them with her fingers in an effort to touch them as little as possible. As she turned toward the hamper to get rid of them she noticed some crusty white flakes falling off the boxers. She wasn’t exactly experienced but she was far from naïve, and recognized immediately what the substance must be. “Yuck!” she exclaimed, feeling nauseated and wondering if she could get the water hot enough to make her feel clean.

Just before she dumped the soiled garments in the hamper an alluring odor tickled her nose. She paused as she tried to identify the intoxicating aroma. With dawning horror, she realized it was coming from the filthy boxers in her grasp. Quite unwillingly, she brought the cloth to her nose and took a deep breath. The moan she let out was completely involuntary as the musty smell of her brother’s used boxers inexplicably sent a shiver of lust through her body. She crushed the fabric to her face for several long seconds as she continued to inhale the heady fragrance of what must be Aaron’s cock and cum. She tentatively extended her tongue and made the slightest bit of contact with the salty flakes before mastering herself once again. Shuddering in shame and revulsion, she quickly dropped the clothes into the hamper and slammed the lid shut.

Jessica jumped in the shower and scrubbed until she felt raw. Her lust had cooled quickly in the face of her humiliation and it took some time before she felt calm enough to clean anything other than her hands and face. She had just started washing her hair when she felt an odd compulsion to start stealing her brother’s boxers. “What the fuck?” she said out loud as she paused her cleaning.

The memory of the naughty thrill she had gotten from sniffing the underwear was still with Jess, despite how much her rational mind wanted to forget it. But there was no way she could get away with something like that for very long, and she felt she might die from embarrassment if she were caught. She tried to return her attention to cleaning herself but the thoughts lingered and eventually crystallized into a plan. “Okay, okay!” she thought to herself, “I’ll do it just this once!”

Jessica finally finished her shower and started putting on lotion and performing her other routines, but her eyes kept bouncing to the mirror and the reflection of the hamper. She forced herself not to hurry despite her increasing anxiety and anticipation. She finally put on her bathrobe and walked over to the hamper. She stood there a full minute or more, resolve wavering, before finally opening it and grabbing the boxers. She quickly brought them to her face for another deep inhalation, letting out a tiny whimper as she did so. Face burning with disgrace, she tucked the underwear inside her robe and tried to walk nonchalantly down the hall despite an inclination to run full out.

Once inside, Jessica locked the door and collapsed on her bed to pull out the garment and smell it some more. She found the odor to be repulsive but hypnotic at the same time. She was mortified to feel her body responding with increasing arousal. “No!” she cried quietly, “I won’t! Won’t, won’t, won’t!” and threw the boxers away from her. She curled up into a fetal position and waited for her shame and unnatural lust to fade.

Not enough time had passed for her to feel normal, but her brother knocked on the door and asked, “You ready yet? If you want me to drop you off at school we need to leave soon!” Jessica gasped and started scrambling to get dressed and ready, not wanting to be late for school and mar her perfect attendance record. Noticing the offensive yet enticing scrap of underwear on the floor, she panicked briefly before deciding to hide it under her pillow. She was in too much of a rush to consider what an odd choice that was.

* * *

Aaron sat on the couch downstairs and pondered his next steps. Up until today he’d kind of resented having to get up early enough to drop off his sister, since both their parents left for work even earlier. It meant he had to sit around for a few hours at his community college waiting for his own classes to start. But now, the time stuck alone in the car with his sister appeared to be a golden opportunity.

Since it seemed like her nose was the path to her heart, or at least the path to her pussy, it stood to reason that any innocent-seeming ways to get her close enough to smell him would help build her arousal and maybe get her to start fixating on him. When they were younger they had often hugged goodbye or hello, on those days that they weren’t mortal enemies for some minor insult, anyway. As they aged and developed, their childhood habit had faded and they rarely touched each other casually anymore. Perhaps he could attempt to restore her old behavior in that respect?

Aaron entered the scenario ‘hugs brother hello and goodbye or as a thank you’ into the app and waited for the results. The base likelihood was 64%, which seemed like an excellent place to start, especially after he boosted it up to 89% with his tokens, expecting to get five more if it succeeded. He sent the command and waited impatiently.

Triumph! Target’s behavior will modify to include casual hugs to subject Aaron O’Neill under a variety of circumstances! Level One tokens earned: 25/50.

“Sweet!” thought Aaron. “I even got myself ten tokens this time! Maybe changed behaviors are worth more because they’re bigger or more difficult than the other options?” He was about to try another experiment to use up his tokens but Jessica was scrambling down the stairs in a rush and went directly out to the car, so Aaron put his phone away for the time being and joined her.

They rode in silence, which was not unusual, but Aaron was paying especially close attention to Jessica’s presence. He might have been imagining it, but he thought she was breathing more deeply than usual, and her cheeks seemed more pink than normal. He wanted to believe it was from smelling his scent trapped in the car, but it might have just been from her rushing and running to get ready, or embarrassment over stealing his boxers. The thought of running gave him a new idea, which he decided to implement right away.

“Hey Jess…” he started, pausing as if he was embarrassed before continuing, “I was wondering if you still wanted me to come jogging with you sometimes? I’ve been thinking I need to get into better shape and thought that might be a good way to ease into the whole exercising regularly thing.” Jessica looked totally shocked, which he had expected.

“I mean, it’s fine if you don’t want to, but I remembered you telling mom you wished you could stay out longer or go farther without feeling unsafe, and it would really help me to have someone along to kind of push me if I try to give up too easily…” Aaron allowed his words to trail off. He glanced over at his sister with a nervousness that wasn’t completely fake to see her still staring at him in disbelief. “Time for the finishing move,” he whispered too quietly for Jess to hear. Trying to look really embarrassed, he concluded out loud, “You know what? Never mind, it was a dumb idea, forget I said anything.”

Jessica finally composed herself enough to respond and said, “Actually, I really would like the company! And I’m glad you’re trying to be more healthy! Do you want to go for a run tonight after school?”

“That sounds great!” confessed Aaron, without having to pretend to be relieved and happy. He wasn’t in bad shape, but his sister was far more athletic, so he was certain he’d be a sweaty mess by the time she felt they’d jogged long enough: a sweaty mess that should get her hot and bothered when she got a good whiff of him.

As they pulled up to the high school Jessica opened the door but hesitated before getting out of the car. She suddenly reached over and grabbed Aaron in a one-armed hug, pressing her face to his neck as she said, “Thanks, bro!” Aaron was sure he heard his sister’s breath hitch while she hugged him, and maybe her cheeks were a little redder than they had been before, as she clambered out of the car and waved goodbye with a small smile.

Aaron waved and smiled back as he drove away, with one thought running through his head: “Triumph!”

Aaron sat in the lounge at his community college and stared at his phone. He was experimenting with the SCORE system to run scenarios for implanting thoughts in his sister’s mind or brain or whatever. So far, every sexy thought he’d modeled had very low odds of success, even with his sister now getting a jolt of arousal any time she smelled him. “Maybe I’m approaching this from the wrong angle,” he thought. “Maybe I should try more stuff like the jogging plan,” remembering that he hadn’t even used the app to get his sister to agree to that idea.

Frowning, he ran through several exercise-related thoughts, most of which had likelihoods in the forty-to-seventy percent range. Since he had plenty of battery power he decided to just send all of them in sequence to see which ones might stick on their own, and then he’d try to build off of those. He briefly considered boosting some of them with tokens but decided to save them for a command that he particularly wanted to succeed. All of these were just intermediate steps in his campaign, and frankly, any successes he enjoyed would result in a lot of work for him somewhere down the line. “What won’t a man do for his favorite girl?” he thought with a chuckle.

Triumph! Target will now think about additional ways to encourage Aaron O’Neill to exercise with her. Level One Tokens: 30/50.

Failure! Target resisted the impulse to think about being Aaron O’Neill’s personal trainer.

Failure! Target resisted the impulse to picture Aaron O’Neill when looking at other men exercising.

Triumph! Target will now think of Aaron O’Neill when she exercises. Level One Tokens: 35/50.

Failure! Target resisted the impulse to imagine Aaron O’Neill when she showers.

Triumph! Target will now think that Aaron O’Neill leaving his clothes on the bathroom floor is endearing rather than disgusting. Level One Tokens: 40/50.

“Holy shit!” thought Aaron. The last one had only been about 6% likely to succeed and he’d added it on a whim, not begrudging the 5% battery power it had taken, which had been a bit higher than usual now that he thought about it. But from the look of things, his sister was going to start thinking of her brother as her exercise buddy and actively plan for ways to spend more time with him, at least as long as it was fitness related. As he imagined his sister stealing his boxers again the next time he left them on the floor, Aaron got a raging erection. Knowing he’d be unable to concentrate on any of his classes until it was taken care of, he shuffled off to find a quiet bathroom to have a quick wank.

* * *

Jessica had been idly thinking about the agreement to go jogging with her brother after school instead of concentrating on her math class, wondering if she could convince him to drive out to a nearby park so they could run on the nature trails it offered. She liked to go there on weekends when it was fairly busy and felt safe, but she and her parents worried that the wooded paths offered too many hiding places for a young woman to safely jog them alone, especially too early or too late in the day. Aaron might not be a whole lot of help if a mugger or rapist actually were to be lurking behind a tree, but just by being there he’d likely encourage most such malevolent loners into waiting for solitary prey.

Jessica was happy that her dark thoughts of ambush rapists suddenly switched to brainstorming ways to get Aaron involved in other fitness regimes aside from just jogging with her. She didn’t do a lot of weight training, but perhaps she could do more, and entice her brother to join her by painting a mental portrait of him with a six-pack and bulging biceps to attract the girls at his school. A brief image of her future ‘fit brother’ posing for a picture as a shirtless body-builder flashed through her mind but she quickly dismissed it.

As Jessica changed into her workout clothes for gym class later that day, she found her thoughts turning to Aaron again and again, no matter how she tried to distract herself with exercising. She blushed when her friends remarked that her spacy attitude must be caused by thinking about a boy. Her red face was taken as proof positive and she spent the rest of the period issuing denials that were not believed and refusing to answer leading questions.

Jess certainly wasn’t fantasizing about her brother the way she did the cute boys in their gym shorts, segregated from the girls on the other side of the gymnasium. She used to enjoy the chance to flirt with a few of them at the water fountains near the doors that led to the locker rooms, but today, every time she got a whiff of a boy’s sweaty musk, she found herself disappointed that it didn’t give her the same thrill as her brother’s unique odor. Shamed and confused by that revelation, she struggled through the rest of the day even more distracted than before. Still, she couldn’t help feeling a thrill of anticipation as she waited for Aaron to pick her up after school.

Aaron pulled up to the high school to collect his sister. She was waiting for him and immediately leaned over to give him another one-armed hug when she got in the car, sniffing audibly but subtly enough that it was noticeable only because he’d been waiting for it. As they departed for home Jessica asked, “So, for jogging, are you okay with going out to McLaren Park? They’re got some really nice nature trails and most of them are loops, so we can just kind of run as many of the loops as we think we can handle.”

Aaron smiled faintly at her word choice; it was clear that she was trying to be tactful and spare his feelings lest he change his mind, because it was entirely obvious to both of them that she could handle a lot more running than he could. He shrugged, not really caring where they went, and said, “Sounds fine to me. We can head straight out after we drop our stuff off at home.”

Aaron debated on giving his sister another command or two while he waited for her to get ready. He tested a behavioral command, ‘will find it arousing if Aaron sniffs me,’ and was pleasantly surprised to see that it started at 44%, and each token added 5% in this case, although the battery cost was 10% for whatever reason. His phone had more than enough charge, though, and he spent ten of his 25 tokens to boost the likelihood to 94%. Unsurprisingly, the app soon said, “Triumph!” and essentially refunded him five tokens, giving him 45/50 for the first level. He was on the point of trying to do another command but Jessica called out that she was ready, so he put his phone away, told their parents where they were headed, and set out.

The siblings were barely ten minutes into their jog before Aaron started regretting his strategy. His sister was clearly trying to sell him on the idea of the two of them joining a gym so they could mix in some weight training with their cardio, which Aaron supposed was probably his fault, too. He tried to sound interested but non-committal, as he didn’t want to shut her down or discourage her, but at the moment he didn’t have the breath to engage in a serious conversation.

Jessica soon gave up trying to talk to him other than occasionally pointing out an interesting sight or commenting on trivial things in their lives. She also kept moving around so that she would be ahead of him on the left sometimes, then later a little behind on his right. It was starting to get annoying, but then Aaron suddenly realized that she was trying to stay downwind of him in order to smell him better. It was starting to get dark, and her cheeks were pink from running, but he thought he could just make out a hint of pokies through her workout top. That idea alone was enough to give him a raging erection, which made running even more difficult. Thankfully, he had switched into boxer briefs before heading out, so his boner was more or less hidden as it tried to push down toward his leg.

The brother and sister kept running and walking until it got too dark to see the trails well. Or rather, Aaron had to resort to walking sometimes, and Jessica would jog to the next bend in the trail and then jog back as necessary. They both stopped to use the public restrooms and water fountain before heading home. Just before they got in the car Jessica grabbed Aaron and gave him a big hug, taking a deep breath and saying, “Thank you so much for coming out here with me!”

Aaron could feel his sister shivering slightly as she inhaled his sweaty odor with each breath, and he put his head beside hers so she could hear him sniff loudly just before saying, “No, thank you for helping me stick it out!” He felt Jess tremble intensely in his arms as he did so. She quickly released the hug and got in the car, and Aaron was pretty sure that some of the red in her face was now arousal and probably shame.

They got home to find their parents watching TV and leftovers in the fridge. Aaron made a bit of a performance sniffing his armpit and saying, “I really need to take a shower, Jess. Are you okay with me going first? I promise I won’t use up all the hot water!” Jessica smirked and pouted dramatically but acquiesced, so Aaron headed upstairs. He turned the shower on cold to cover the sound of his rapid wanking and made sure to leave his cum-stained boxer briefs on the floor for his sister to find. Adjusting the temperature of the shower up to warm he quickly cleansed himself and rushed to his room, shouting, “Bathroom’s free, Jess!”

As Jessica started her own shower Aaron opened up the ADMIN app and tried to send a thought command to his sister, ‘it would be really hot if Aaron liked smelling me as much as I like smelling him.’ This had only a 17% chance of success, and each of his 20 tokens were only good for a 2% boost each. He had enough battery power to take six cracks at it before he needed to recharge, so he decided to try his luck with five attempts at the base difficulty, and if that didn’t work he’d dump all his tokens on the last one. The roughly one-in-five odds did not pan out in five attempts, however, so he crossed his fingers on a final toss at 57%.

Triumph! The target will now be aroused if subject Aaron O’Neill smells her! Level One Tokens: 50/50.

Aaron had been expecting some kind of dialog to pop up telling him he’d advanced to Level Two, but nothing happened. Curious, he went back to the leveling menu and tapped on the second level, which sure enough brought up a tool tip of sorts.

To advance to Level Two, the target must either respond positively to a flirtation initiated the subject or must initiate a flirtation of their own.

“Well, that might pose a little bit of a dilemma,” Aaron thought. He’d been enjoying steady progress, but a lot of the best results had come from massive token expenditures. He had five left, and should get ten more tomorrow, but he couldn’t count on any more bonuses from successful commands. He laid down on his bed and thought, absently noting that the shower had stopped. Just as he heard his sister heading back to her room his phone sounded a fanfare. He looked at the screen in confusion.

Congratulations on reaching Level Two! Now that you and your sister are flirting, it’s time to elevate your game! Smoky looks and lingering touches are all well and good, but you can’t be sure you’re on the right path until it’s sealed with a kiss!

Aaron was baffled. He certainly hadn’t done any flirting lying on his bed in his room. And Jessica hadn’t knocked or texted or anything after her shower. So what kind of flirtation could possibly have triggered the app? Maybe she left a note in the bathroom? Well, that would be easy enough to check.

Aaron swung out of bed and headed down the hall, wondering what he might find. He thought his sister’s door might be open the tiniest little bit but decided to ignore it. He entered the room and turned on the lights, glancing around. His dirty laundry was again picked up, presumably placed in the hamper if it wasn’t stolen. He turned to check the clothes bin and that’s when he saw it.

Sitting atop the hamper was a pair of his sister’s panties, probably the ones she had just taken off, judging by the sweat stains. He reached out for them with a trembling hand and brought them to his face, deeply inhaling Jessica’s scent. Despite having cum less than an hour ago his cock was rampant again, and he was sure he could detect a faint aroma of his sister’s arousal underneath the salty tang of her sweat.

Aaron crumpled the panties into a ball in his hand but made sure enough of them were hanging out to be easily identifiable. As he walked back to his room he made sure to give his sister a clear view of the fabric in his hand, assuming she was watching him. Aaron was certain he heard Jessica’s door close with a soft click just as he entered his own room to beat off again, thinking, “Triumph!”
