ADMIN: INCEST QUEST
(Friday Evening)
Aaron's erection did not subside during the entire drive back home, thanks in part to Jessica's hand resting on his thigh, lightly massaging it, and her insistence on nuzzling his neck at every full stop along the way. They were both relieved to see that their parents were indeed out on a date, meaning they should have a least a few hours to themselves. Their new habit of kissing and groping in the garage persisted, even though they could have carried the action into the main house safely.
Gently biting her brother's lower lip, Jessica stared mischievously into his eyes and grinned. Releasing her grip, she breathed into his ear, "You know what we should do now, bro?"
Aaron's skin got goose pimples from the warm air and he croaked out, "What should we do, sis?"
"Well, you've already seen me in two bikinis, so there's not a lot of point trying on the others. More of the same, right?" she asked quietly while licking her brother's neck.
"I guess that's true, although I'm all for third and fourth helpings, honestly!" he said, palming his sister's tight, athletic ass cheeks through her pants.
"Then let's go do some aerobics!" Jess said brightly.
Aaron's mind conjured up the needle scratch noise as his train of thought abruptly derailed. "What?" he asked, completely baffled.
"I got myself some new workout clothes!" she said happily. "And since we didn't go jogging together today, maybe we can just stay in and do some cardio in front of the TV!"
To say Aaron was disappointed would be a gross understatement. Still, given Jessica's new choice in swimwear, there was every chance that her new exercise outfit would be titillating in its own right. And to be fair, his master plan did involve using fitness to get in her pants, or for starters, to get her out of them. Doing his best to look enthusiastic, Aaron gave a patently fake grin and said, "Great idea!"
Jessica laughed, clearly not deceived by his false eagerness, but kissed her brother on the lips and said, "No need to be so glum! I promise you'll enjoy the experience!" Grabbing her bags from the car, she headed into the house and called out, "Meet me in the living room in five minutes!"
Aaron went to get changed and was soon back downstairs, although he paused long enough to check the ADMIN app. As expected from the fanfare, it told him that Jessica was now ready to be fully undressed around him, so he expected the night would end with some viewing pleasure at the very least. The next stage was the first of the overtly sexual ones, as it involved manually pleasuring one another. The quest level would be complete once both of them brought the other to an orgasm with their hands. Aaron didn't have time to do anything major just then, so he quickly sent his sister an amended version of her existing belief that it was flirtatious to brush up against his cock when clothed. It took two tries, but he succeeded at making his sister feel that it was flirtatious behavior even when it was skin to skin contact.
Aaron was standing around in the living room waiting. Somewhat more than five minutes later his sister walked in, causing his jaw to drop and his cock to rise. Jessica grinned at his stunned gawking and gave a little pirouette to showcase her whole outfit. The spin was hardly necessary, considering her ensemble consisted solely of a pair of panties that barely covered her sex in the front. From the back only the strings over her hips were visible, as whatever tiny amount of material connected them to the gusset was swallowed by her buttocks.
"I know you love my sweaty clothes as much as I love yours," Jessica said, "But as long as we're working out alone, there's no need to make a big pile of laundry, is there?"
Aaron gulped and replied, "I guess that makes sense!" while staring at his sister's exposed breasts, flushed red and with swollen nipples straining for attention.
"Good! Then let's get you out of those heavy things!" said Jessica, kneeling down to pull her brother's basketball shorts and briefs off, laughing as his hard-on slapped her in the face but pulling away slightly with embarrassment. "After all, the original gymnasiums were all-nude institutions!" she added as she got back to her feet and tossed his clothes on the couch.
Throwing his tank-top to the side, Aaron felt both weird and aroused to be standing in the living room completely undressed. Responding to his sister's jibe, he pointed out, "That makes you a little overdressed for the occasion, then, doesn't it?"
Jessica put on a mock thoughtful expression for a few moments and then said, "You're right!" With no further ado, she dropped her panties to the floor and posed with her legs slightly spread, breathing heavily as she exposed herself fully to her brother for the first time, eyes locked on the purple head of his cock as a small bead of precum forced its way out.
"Oh, geez," groaned Aaron as he squeezed his dick painfully, worried for a moment that he might bust his nut just from the sight of his naked sister displaying herself for him.
Jessica seemed to realize the situation, and her eyes were very bright when she locked gazes with her brother and huskily said, "Let's get started, then, shall we?"
Turning around and bending over provocatively to grab the remote, Jess flicked on the television and selected a recorded program that she often used. She gave her brother another mischievous grin as she started her warm-up stretches, apparently unconcerned that he had no attention to spare for the show running in the background. At her insistence, Aaron started doing whatever she did, as best he could mimic, although he had no idea what exactly the exercises were. All he could concentrate on was his sister's body, gloriously nude and soon slick and shiny with sweat. He did his best to commit her every line and curve to memory, trying to burn the sight of her flexing glutes and bouncing breasts permanently onto his retinas.
Aaron was shocked to realize it had been an hour when Jessica abruptly stopped mesmerizing him with her movements and turned the TV off. "Heck of a workout, huh, bro?" she panted, clearly almost as turned on as he was, but powering through it with a bit more aplomb. She grinned as he made eye contact again and raised her arm to sniff at her armpit. "Whew! That's pretty smelly! What do you think?"
Aaron grinned back and accepted the invitation, striding over to Jessica and bending down to stick his face in her pit, thrilled to feel his erection pinned against her belly as he did so. He grabbed his sister's sweaty ass in a tight grip as he sniffed and licked at her stubbly underarm, almost growling with lust. Jess moaned with arousal as well; one of her hands ran up and down Aaron's arm and across his back while she grasped his hair with the other, nuzzling and licking his neck.
The stimulation finally proved too much for Aaron, and before he quite knew what was happening, his cock started spasming as it slid back and forth against Jessica's sweaty skin. He pulled back slightly and his sister gasped as his second and third jets hit her on the underside of her chin, slowly dripping down to join the subsequent weaker shots that ended up splattered across her breasts and belly. "Oh, fuck," he groaned, doing his best to remain standing even though his knees wanted to buckle from the strength of his orgasm.
Jessica recovered from her surprise quickly and grasped her brother tightly to make sure he didn't pull too far away. Once his dick subsided she pulled Aaron into a firm embrace, smearing his cum all over his own torso while she kissed him passionately. "What a mess!" she whispered eventually, finally releasing him and letting him fall wearily into a chair. "Yes, very messy," she affirmed. She leaned her hands on Aaron's thighs and began licking the cum from his belly, making him twitch and struggle not to laugh at the ticklish sensation.
Smiling, Jessica made it into a bit of a game, moving small globs of his seed around until he couldn't resist laughing, then quickly gobbling up as much as she could while he regained control. Aaron was surprised at just how effective his self-command to enjoy nipple play was, groaning with intense lust as his sister sucked on them after cleaning away the jizz. He was soon painfully erect again, to her surprise and admiration.
Jessica abruptly turned around and seated her naked ass on Aaron's lap, trapping his dick between her cheeks somewhat painfully, but he was in no mood to complain. Leaning back against his chest, she asked, "We're going to wind up fucking each other before long, aren't we?"
A little surprised and unnerved at the directness of her inquiry, Aaron hesitated for a moment before saying, "I think so. I hope so. I mean, I want to, and I think you want to, also. So, if we both want to, we probably should."
Jessica giggled weakly and murmured, incredulously, "'Probably should?!' Oh, lordy, what a thing to say!"
Aaron laughed softly and admitted, "Okay, that might have been the wrong way to phrase it, sure. But the rest of it is true enough. I love you, and you love me, and that overrides everything else, I think."
Jessica hummed and said, "Maybe." They sat there for a while, enjoying the closeness, but started to get a little uncomfortable as their sweat dried and made them itchy and cold. "Will you make me a promise, big brother?"
"What kind of promise?" he asked cautiously. "You're not going to try to trick me into promising you my car like when you were twelve and wanted my bicycle, are you?"
Chuckling at the reminder of innocent childhood pranks, Jessica replied, "No, nothing like that. It's just, prom is basically two weeks away. I want you to promise me that we won't fuck until at least after the dance."
Aaron tickled his sister's belly a little and said, "That should be a fun conversation with your date: when exactly he should tag out of the ring."
