ADMIN: INCEST QUEST
Chapter 12
The Last Weekend Before Classes
Aaron had spent the rest of the summer trying to learn more about the ADMIN app, frustrated and alarmed that it had vanished as mysteriously as it had appeared. Nothing useful could be found online, although in retrospect he realized that such a program was hardly likely to advertise its presence to the world. No trace of it remained on his phone, although its effects were still lingering. Aaron worried sometimes that Jessica would wake up one morning and be back to just his sister, possibly his horrified and outraged sister, but so far, her desire for him seemed more intense, if anything.
After consultation with her doctor and some soul-searching, Jessica had agreed to stop taking birth control and use other means to manage her condition. They both thought it quite likely that her increased libido was a side effect of the change in medication, but neither was upset by the fact. It might also have been psychosomatic, as they both knew that she could get pregnant at almost any time, even though the odds were still only slightly above zero for any given event. As full of his sperm as Aaron kept his sister, though, he figured their chances of success were about as high as he could possibly make them.
Aaron admired Jessica's nude form as she lay stretched and cuffed to the spare bed, nestled in amongst their already-dirty clothes. He eyed her legs and bush critically, thinking that she had actually gotten slightly more hirsute since she stopped with the birth control. Running his fingers through her pubes made Jess moan around her gag and try to thrust her hips to intensify his touch. Smiling, Aaron pulled back a little to continue teasing his sister with light caresses.
"Now, now, pet," he said softly, "We agreed, only one orgasm before dinner. You don't want to get it over with too soon, do you?" Jessica gave a resigned groan and shook her head, lowering her hips again. "That's my good girl!" Aaron said with satisfaction, watching as the praise made his sister shiver with pleasure. The aroma of her aroused sex permeated the room, and he dipped his fingers slightly lower to collect some of her moisture, bringing the damp digits to his nose and inhaling deeply. Jessica's eyes narrowed with lust as she watched him slowly lick them clean, keeping eye contact the entire time.
Aaron grasped his cock and slowly ran the head along Jessica's leg. They'd inadvertently discovered that the commands he'd given her brain made any touch from his dick pleasurable, even outside her pussy or ass, so it had become a favorite form of foreplay. Jess tried to follow his progress with her eyes as best she could, although certain places on her skin gave her such intense sensations that she couldn't keep them open or keep her body still. Aaron traced his way down his sister's leg, leaving a faint trail of precum clinging to her hairs, admiring the way goosebumps would raise in the vicinity, puffing out her hair, and gradually subside as he moved along.
The back of her knee was one such unexpected erogenous zone, and Jess did her best to keep her leg flat on the bed to maximize the pressure when Aaron slid his erection partway under her leg. His sister groaned and twisted her upper body in ecstasy, letting her head hang backwards as her breasts were thrust high, nipples almost visibly throbbing, or so Aaron imagined. He didn't linger, but made a mental note to try binding her legs some night and literally trying to fuck them.
The real prize was lower, and Aaron grinned as he got ever closer to Jessica's ankle, winking at her staring eyes as he dallied and traced circles and figure-eights on her calves to prolong the moment. He marveled at her intense reaction to merely touching the crown of his cock to the area around her ankle. She'd described it as something like being tickled, but different, and he supposed he might never truly understand what she experienced. It was enough for him to know that she loved it, although with the way it made her legs jerk out of her control sometimes, one kick in the nuts was enough to make it a treat she only got when she was restrained.
Aaron spent a little time poking his dick around Jessica's toes and the soles of her feet, making her laugh around her gag and twitch. He leaned down to sniff and lick at them, which in some ways only intensified her reaction. He still felt a little weird to be using her feet in sex, as it wasn't precisely a fetish for either of them
per se
, but under the right conditions he loved the smell. Her scent was strong there, and as long as it didn't get too stale inside a shoe, he found it would give him an instant erection if she stuck one in his face. Being naked and barefoot around the house gave her frequent opportunities to do so.
Repeating the process in reverse on her other leg, Aaron smiled and breathed in deeply. Fresh sweat from her exertions against the restraints had been added to the somewhat funky smell of their dirty laundry. As he reached her hip again, he asked, "Is my pet ready for her fucking?"
Jessica nodded her head eagerly, moaning and begging with her eyes. Aaron didn't waste any more time, as he was nearly as pent-up from taking the time to tease his sister so thoroughly. Even if he hadn't rigged things to ensure that she would come any time he did, at least when he was in her pussy, he was pretty sure that it would rarely take either of them more than a minute or two to finish off after such slow denial. He slid in with no resistance other than her clutching muscles and began pounding her frenetically. Jess responded in kind, to the extent she was able, twisting her hips to meet his thrusts and taking him as deeply as she could.
Their climaxes rendered both siblings unintelligible, even though only one was gagged. Aaron's eyes were closed for the first several spasms, but before he completely finished he looked down and saw Jessica looking up at him. It was his favorite single moment from their encounters, although he couldn't precisely say why. He'd tried to explain it when Jess asked, fumbling for words, but she'd just kissed him on the cheek and said she already knew what he meant.
The moment eventually ended, and Aaron slowly lowered himself until he was laying on his sister. He was no longer concerned about crushing her, as she'd admitted to liking the feeling, at least for a little while afterwards. He did make a point of reaching up and undoing the buckle that held the ball gag in place, as Jessica preferred to have that removed much sooner than any of the other restraints.
"Thanks, lover," she said hoarsely, working her sore jaw and rubbing her face against his hair to wipe off the drool. Aaron winced and laughed, but no longer recoiled when she used him as a spit rag.
"My pleasure," he teased, moving his hips a little.
"Only for now," she quipped back, "When we're married, half of yours will belong to me, plus all of mine."
"Oh, is that how that works?" he asked, lightly and rhetorically. They both knew that a true marriage was off the books, but they considered themselves almost as good as married already. They'd had a few tentative discussions about having some kind of private ceremony to make it seem official, if only in their own minds, but had tabled the discussion as being more appropriate for after graduation, or at least some point further down the line.
