Incest Quest (An ADMIN Tale) Ch. 07

The tiny scrap of fabric was too tight for his fingers to get under, so Aaron impatiently moved the gusset to the side and ran them up and down Jessica's lower lips. She whined needfully, possibly even deliberately trying to sound like a dog, and quietly said, "Yes, please!" He eased a digit into her folds in response, experimenting to see what she seemed to like the most and being somewhat gratified that everything he tried resulted in happy noises and more plaintive and inviting whimpers.

Sooner than he would have expected, Jessica was muttering, "I'm cumming!" Aaron felt her muscles clenching on his fingers and smiled pridefully at his accomplishment. He kissed his sister's cheek and ear, nuzzling into her hair and making sure she could tell he was sniffing her. He brought his fingers up to her face once her contractions eased, but had second thoughts about either of them licking the digits clean, realizing that most of the moisture on them was actually lake water. He settled for loosening his embrace and letting her turn around to kiss him instead.

"Are you ready for another wank?" Jessica teased, sniffing around Aaron's ear and throat playfully.

"If you keep squeezing me like that, yeah, I'm gonna cum pretty quickly," he admitted.

"Stop me before you do, I want to try something different," she breathed, picking up the pace of her gentle stroking and tightening her grip on her brother's cock.

"I'm almost there!" Aaron groaned softly a minute or two later, then more loudly when Jessica abruptly released his member and splashed back toward the shore.

"Follow me!" she cried. Aaron gripped himself tightly, not liking the absence of his sister's warm hand in the cool lake water, and slightly worried he would lose his impending orgasm. The sight of Jessica stepping out of her bottoms and laying on her towel ass-up kept his spark alive, though, as he stumbled awkwardly up the bank.

Looking over her shoulder seductively, Jessica purred, "I want you to come all over my ass, big brother." She reached back and spread her cheeks a bit, giving Aaron a clear look at her asshole and the slightly furry slit beneath it. He groaned as he dropped to his knees behind her, tugging furiously on his cock. With a loud groan, he finally unleashed, watching raptly as a few streaks of his pearly essence landed on her firm buns and in her crack. Jessica was also hissing with pleasure, and he could see the muscles in her buttocks spasming.

Aaron was still catching his breath when Jessica handed him her phone, demanding, "Take some pictures! It feels sexy, but I want to see it the way you do!" He obliged, snapping several still shots and then a short video of his fingers rubbing his cum into her beautiful skin. Feeling bold, one of his digits dragged a small glob of his seed and poked it just slightly into her anal opening, making his sister gasp and stare at him wide-eyed. He decided not to press the issue, at least until he used his app to gauge her interest in anal play, and simply smiled and handed her the phone, withdrawing his finger.

"Go ahead and put it back in," Jessica moaned, surprising Aaron, as she raptly gazed at the pictures and video. He could see her masturbating as he eased his pinky back into her anus, unable to fully process his amazement when he realized he could feel every plunging thrust she made with her fingers through the thin wall separating her two cavities. They groaned in unison as she got herself off again, clenching so hard that he wondered if he could have removed his digit at all.

(Monday Afternoon)

Jessica sighed with boredom as she reclined on her bed, idly playing with her pussy and channel-surfing through her fantasies of Aaron and his iconic cock. Having already gotten herself off twice that morning, her current masturbation was more of a means of keeping her arousal simmering than seeking another release. But with her parents likely to get home before her brother, she wasn't sure she and Aaron would have sufficient privacy to do more than sext each other some more. Pouting, Jess pulled her hand out of her panties and sat up.

Although it was not unexpected, their parents had decided to ground Jessica in response to her suspension from school. That had been one of the reasons she had been so anxious to get to the lake on Saturday, to squeeze in a day of fun before the hammer dropped. To be fair, she didn't think the punishment was harsh, and they hadn't seemed particularly upset about hearing she'd been fighting. Jess had been a little worried that the school might have mentioned she'd admitted to sexting someone from the bathroom, but if they did, her parents had chosen not to comment.

On the bright side, her grounding was conditional about forays with her parents or brother, and they'd already agreed that Aaron and Jess could continue jogging and going to the gym together. A large part of her nervous energy was the anticipation of getting out on the trails in a few hours where she and her brother would have some privacy to flirt and maybe even find a quiet place to get one another off.

Her teachers had emailed Jess assignments to work on during her suspension and she was already well ahead of where she needed to be. Unable to concentrate on schoolwork any more that day, she got up and wandered into Aaron's room, not entirely sure what her plan was. She nuzzled her face into his rumpled sheets and inhaled deeply, loving his scent and finding that it was almost as good at keeping her libido percolating as playing with her kitty. She crawled around on his bed then, growling softly to herself and slowly removing her clothes.

As much as she loved the way Aaron smelled, Jess loved their combined aroma even more. She burrowed into his blankets and began energetically frigging herself, trying to use the cover of warm bedding and aggressive activity to make herself sweat. Jessica growled any time she got close to cumming and forced herself to back off. The sense of confinement, restraint, and denial all contributed to leaving her a panting mess. When she was sure she couldn't take it anymore, Jessica struggled free of the sheets and grabbed her brother's pillow, shoving it between her legs and humping it vigorously. Moments later she let out a howl as she started cumming, but quickly forced herself to a quiet whine as she heard the garage door opening, signaling her parents' return from work.

(Monday Evening)

Aaron was getting better at keeping pace with his sister while running, or else she wasn't going as hard as usual. She'd started out at a sprint he couldn't hope to match but had slacked off and waited for him to catch up, giving him a kiss and a sniff when he did. They'd pawed at each other a little but kept things relatively tame since there were a handful of other joggers around, albeit none close by. When Jessica turned and jogged down a four-mile loop he frowned and gasped, "I'm not sure we'll get back before dark if we go that way!"

Jessica turned back to wink suggestively and gave her brother a brief flash of her ass, clad in skin-tight exercise pants that molded to her firm cheeks when they weren't being pulled down. "Is that a problem?" she asked coyly before tugging things back into place and darting away again.

Aaron shook his head and smiled ruefully. He loved how flirty his sister had become, but after their various misadventures at the lake he was a little more concerned about the consequences of getting caught. Their fun times would end in a hurry, he was sure, if they did anything serious enough to get the authorities involved. Yet he couldn't bring himself to do or even say anything that might curtail her playful sexiness.

At the halfway point of the loop there was a covered pavilion with some picnic tables and a composting outhouse. Once upon a time a hand-pumped well could be used to get a refreshing drink, but the well had gone dry years before as the water table dropped. When Aaron finally stumbled to a halt and bent over to catch his breath, Jessica was straddling the handle of the pump and struggling to push down on the rusted apparatus, slowly forcing it to move.

"That thing doesn't work anymore," Aaron said between wheezes, "I don't think it has since we were kids."

"I wasn't trying to get water," Jess teased, "I was just enjoying the feeling of something long and hard between my legs."

"Such a naughty little lady!" Aaron panted, moving closer to his sister while clutching a stitch in his side. "Have you been feeling neglected all day, stuck at home all alone?" He bent close to Jessica's neck and licked at the salty drops of sweat clinging to her skin, making a soft growling noise that she returned in kind. Soon, both siblings were standing and embracing, their bodies pressed tightly together and hands wandering, while they took turns kissing and licking each other's faces and necks.

Jessica abruptly pushed Aaron away slightly and stripped out of her top, flashing her fuzzy pits in the process. Although only a little more than stubble still, the sight of her growing hair made his cock twitch. "Follow me!" she said, somewhat breathlessly, as she dashed into the bushes surrounding the small clearing.

Once the siblings were partially concealed from the trail by the screen of leaves, Jessica gave Aaron another fierce but brief kiss, moving his head to her sweaty, exposed breasts. Taking the hint, he eagerly licked and sucked at them, focusing on her nipples while massaging her firm ass with his hands. His sister's fingers were tangled in his hair as she quietly moaned and whimpered, "Yes!" repeatedly. Their hips collided over and over again as neither could resist the urge to hump one another.

Aaron loved the grunts and whimpers Jess was making. She was a little bit noisier than normal after he pushed new, more animalistic behavior on her the night before, which might have something to do with her increased aggressiveness as well, he thought. Of course, that might just have been normal for her, if she'd ever previously had a relationship that had gotten so hot and heavy. Whatever the case, Aaron loved it.

After several minutes of breast play and groping, Jessica suddenly dropped to her knees and yanked down Aaron's pants and boxer briefs in one fluid motion. She kissed the tip of his erection and swabbed away a drop of his precum, making his breath catch in wondering anticipation. Jess pulled her head back, however, humming appreciatively at the taste of his lust, and proceeded to use her sweaty hand to stroke his member energetically. "Let me know if I do something wrong," she exhaled, looking up at her brother with bright and adoring eyes.

Aaron gazed down at Jessica with the same loving expression, reaching out to gently pet her head and replying, "You're doing great, Jess." He resisted the urge to let his smile turn into a smirk when his sister's eyes closed and she visibly shuddered at his praise. That was another new behavior he'd instilled that morning, making her become more aroused any time he praised her. It had taken most of his tokens to ensure it stuck, but he'd noticed he had a similar natural reaction to her compliments and figured it was only fair to give her the same thrill.

While Jessica's technique was perhaps a little less polished than his own, Aaron found that it did not detract from his enjoyment in the least, and he was more than ready to oblige his sister a few minutes later when she croaked, "Cum on my face, big brother!" He twined his fingers in her hair as he let loose, grunting loudly as his seed gushed forth. Jessica let out a happy-sounding yelp and opened her mouth wide to catch as much of his essence as she could. When Aaron finally stopped spurting, his sister nearly gave him a heart attack when she pursed her lips on the head of his cock and gave a strong suck, followed by a few licks, to claim all of his cum.

"This stuff is borderline addictive!" Jess exclaimed as she used her fingers to wipe her face as best she could, sucking them clean afterwards. Once done, she dipped those same fingers into her glistening folds and held them up for Aaron to taste. He happily took them in his mouth, swiping over them with his tongue, loving the taste and smell. They kissed a few minutes, but Jessica deflected her brother's efforts to finger her in turn, saying, "Let's wait until we get back to the car, it should be dark by then."

Finally separating, the siblings fixed their clothes and got back on the trail, both of them somewhat satiated by their antics but eagerly looking forward to more.

(Wednesday Morning)

Jessica had gotten into the habit of sleeping in just a pair of panties, and thought she might have preferred being entirely nude if not for the joy of seeing her brother sniff her dirty underwear. They were still a little cautious about doing too much at home, but masturbating until they made a mess of their undies and trading them for another session of self-love was at least somewhat sneaky. For the last couple of days she hadn't bothered getting dressed to walk into Aaron's room and strip down for their exchange, knowing their parents were already gone.

Possibly Jessica's new favorite hobby was masturbating in her brother's bed. Aaron had responded very favorably when he discovered her scent and the evidence she'd left stained on his pillowcase, and his praise was enough to ratchet her arousal up several notches. She wished he could do the same in her bed, but so far there hadn't been time, so she'd had to make do with swapping their dirty sheets around, so that they could both sleep surrounded by their mixed aromas.

Feeling extra naughty this morning, Jess had gathered up all of the pens, pencils, and other remotely phallic objects she could find in Aaron's room and dumped them on his bed before making herself comfortable. She used her fingers to warm up while looking at pictures of his iconic dick on her phone, gradually inserting more and more of his possessions into her pussy, marking them with her smell. Once she had as many rammed inside as she could comfortably fit, she stuck a few more in her asshole, shuddering at the depraved feelings it evoked. It took a few attempts to get a good picture of her snatch, but she figured it would brighten Aaron's morning to see her impression of a pencil case.

Jessica stroked at her ever-more-fluffy bush while she waited for her brother to respond, pleased at how quickly it was growing back now that she'd stopped shaving. Her legs and armpits also appeared to be making up for lost time, seeming to go from stubble to short hairs almost overnight. Her thighs had relatively little hair to begin with, but she enjoyed the look and feel when she rubbed her fuzzy calves against each other.

Aaron finally messaged back, and the short video of his ideal cock spraying a fountain of jizz into a toilet made Jess growl lustily. She flipped over onto her knees and nuzzled her brother's stained boxers, sucking on the fabric to extract the flavor of his mostly dried cum while she expelled the pens from her privates and replaced them with her lone sex toy, a thin vibrating wand. It wasn't practical to record her vaginal antics for Aaron's enjoyment, but she did send him a short clip of her 'O' face, with half-lidded eyes and teeth bared, still clenching his soiled underwear.

She and Aaron sent several more flirty messages back and forth while they recovered from their climaxes, and Jessica wondered once more if she could control herself until prom. She finally sighed and tidied up a little, returning the pens and other items to her brother's desk but leaving the rumpled sheets as they were. Still nude and restless, she wandered down the hall, looking for Aaron's toothbrush.

(Friday Afternoon)

Aaron had spent the week largely holding off on any major uses of the ADMIN app, slightly worried that he may have already overdone it a little in making his sister into a horny pervert. He had been particularly alarmed at dinner on Thursday, when she had stopped using her cutlery despite the meal being meatloaf and mashed potatoes. Even their parents had seemed a little off-put and didn't entirely believe her claim that she was simply very hungry from the long run she and Aaron had just returned from. Immediately afterwards, he amended his animalistic behavioral modification to specify sexual situations only, hoping that it would be enough to keep her table manners reasonably intact, at least for now.

Jessica's latest message had Aaron's pants threatening to burst, however, as he carefully navigated home. She'd sent him a picture of herself deep-throating a rather large carrot, along with the explanation that she'd been watching instructionals and practicing all week, and that she thought they should take the next step that night rather than Saturday like she originally suggested. For one thing, their parents would be on their normal date, and their mother was planning to take her shopping for a prom dress on Saturday.

Aaron noted that their parents were already gone when he pulled into the garage, and felt his heart beating rapidly with anticipation. The overworked muscle nearly stopped when he walked into the living room and saw his sister kneeling on the floor at the foot of the stairs, naked except for the choker he'd given her. Jessica's arms were behind her head, showing off the dark hair of her arm pits, still somewhat short and currently bunched together with the sweat that glistened on her skin. Her knees were spread apart at about shoulder-width, exposing her furry muff, also matted with moisture, and the pink petals it protected almost seemed to be glowing.

Jessica smiled deviously at her brother's stunned expression and said insistently, "It's time, big brother. Give it to me. Now!" She opened her mouth and pursed her lips, making her desires even more obvious. Aaron had been imagining going down on his sister first, as it seemed somehow more gentlemanly and maybe even romantic, but his resolve wavered and broke at the sexy and stubborn look in her eyes. He finally smirked a little in response and nodded his head while undoing his pants and stepping out of them.

Aaron's cock bobbed a bit as he stepped forward and aimed it at Jessica's lips. Her hands remained behind her head, however, so he took that as implied permission to play about a little, so he rubbed the crown against her cheeks and nose, smearing them with his precum. Her eyes never left his face while he did it, and Aaron found it difficult to break her gaze, thinking it might even be the most exciting element of a scenario that already seemed like a fever dream. He groaned and had to resist an impulse to close his eyes and throw his head back as his member slowly slid into Jessica's warm, wet mouth.

Aaron had intended to take things kind of slowly, knowing that this was his sister's first real blowjob, but he hadn't counted on her drive to excel and a week of boredom and increasing sexual frustration. Although he wasn't going to be winning any awards for the size of his package, he was definitely longer than Jessica's mouth was deep, and he didn't want to choke her or otherwise make her introduction to oral sex painful or distressing. Jess had clearly prepared herself for this moment and wanted to show off her skills, however, and when her brother didn't move fast enough to suit her she lunged forward aggressively, forcing his dick into her throat.

Aaron nearly choked in sympathy as he felt himself lodge in Jessica's throat. Although her eyes watered a little, she didn't seem to be very bothered, and the tightness was exhilarating. She flexed her muscles and forced him most of the way out before repeating the trick. His hands twined in her hair, at first just holding her head, but he gradually started pulling and thrusting in time with Jessica's lunges, helping her to take his shaft completely. When her lips finally pressed forcefully into his pubes, Jess let out a lustful and satisfied moan that reverberated through Aaron's dick, nearly setting him off.
