The Foundling
Chapter 6: Brother & Sister
Abby stirred sleepily, opening one eye to glance at the old-fashioned analog clock on her bedside table, which showed that it was already after ten in the morning. She snuggled back down in the blankets, pushing her naked back against the bare breasts of her foundling sister, who was once again spooning her as they slept in the nude. She was reluctant to admit it, but she couldn't remember ever sleeping as well as she had the last couple of weeks, whether because of the lack of clothes or the post-orgasmic satisfaction that was an almost nightly ritual ever since her sister moved in. Either way, she was getting quite accustomed to it, even if the thought of how wanton it made her seem still caused the occasional blush of shame.
"Good morning, sleepyhead!" said Shannon, reaching around to cup Abigail's sex, running a finger through the lips and making her shiver with pleasure. "Looking forward to a weekend without the parents around?" she whispered teasingly, tickling Abby's ear with her breath.
"Meh," she replied, struggling to keep her hips from moving too much. "They left us so many chores to do, I doubt we'll have much time for fun." She squirmed as the digit gently probed her, trying not to moan out loud.
"Oh, I think we can squeeze in some shenanigans," Shannon said mirthfully, licking and kissing at Abby's earlobe, finally provoking a groan of lust. The dam broke, and the girl's whole body began moving in time with Shannon's rhythm, although she still tried to keep her sounds of pleasure as quiet as possible.
Just before Abby reached a peak of satisfaction, the fingers and lips were withdrawn, and Shannon bounded out of bed. "We'd better get hopping if we're going to finish our errands!" she chirped, bending over to rummage in the bottom drawer of their dresser. "I even got us special matching thongs to wear while we work!" She tossed a small scrap of fabric on the bed near her sister as she pulled hers on, which barely covered anything. Her mound and tuft of pubic hair were clearly visible through the almost-transparent cloth.
Groaning and then sighing, Abby complied with the implicit demand, having gotten quite used to wearing whatever Shannon suggested. The filmy material was almost immediately soaked with her juices, increasing its translucence, although that was more indicative of the small size of the panties than of the quantity of her leaking lubrication. She expected it to be paired with a too-short skirt and something that would show of her boobs, but she wasn't prepared for her sister's answer to the question of what else they were wearing.
"Nothing!" Shannon said brightly as she brushed away her bedhead. "It'll be really sexy to walk around the house with nothing but our panties on!"
Abigail sputtered as she tried to articulate any of the dozens of objections that immediately sprang to mind, but not a single one made it past her lips. The most she could do in protest was emit an anxious squeaking noise, which made Shannon laugh again. She strutted back to the bed and sat down beside Abby, beginning to brush her sister's hair. The relaxation of being pampered helped her to find her voice, but the closest she could come to a denial was a weak expression of concern: "But Jake will see us."
"I know!" gushed Shannon, sounding excited as always. "That's the best part! He'll go completely bonkers when he gets a peek at your titties!" She tossed the brush aside to cup Abby's breasts from behind, squeezing and bouncing them. Abigail privately thought Shannon's were much nicer than her own, although they were a close match in size and shape, and she was well aware of how much attention they got from the rest of the family. It wasn't until that very moment that she realized her own had been drawing nearly as much admiration, and the sudden epiphany made her gasp with lust, bloom with pride, and cringe with shame all at once. She didn't understand how she could have remained so oblivious to the stares for so long.
"This feels... wrong," Abby muttered.
"Oh, pooh!" said Shannon, "It's perfectly natural to enjoy admiring sexy people, and to enjoy being admired for your sexiness!"
"But, family..." Abigail tried to protest, though she quickly trailed off.
"Totally beside the point!" Shannon stated firmly, standing up. "Now, let's go downstairs! I think Big Brother is already outside working on the lawn, anyway!"
Feeling a very slight sense of relief at the reprieve from displaying herself to Jacob, Abby reluctantly followed her sister out of the bedroom. They paused to take care of their morning rituals first, and then decided to go ahead and clean the bathroom while they were there. Abigail's breasts weren't huge, but they were big enough to bounce and sway distractingly as she wiped and scrubbed. At first it was surreal to be working topless, and almost bottomless, but she was slowly able to put it out of her mind and concentrate on the chores.
The two sisters worked their way downstairs, quickly tackling vacuuming, dusting, and sweeping, while the lawnmower droned quietly from outside. Abby recalled that it always took Jake a long time to cut the grass; he was a little OCD about it, and walked very slowly to ensure perfectly straight lines. She ordinarily resented it, since it usually meant more work for her, but if he dallied long enough, she thought it might be possible to go upstairs and get dressed before he even came back inside.
The girls finished the dishes and Abby glanced at the clock, shocked to see it was only half-past one, and all of the indoor chores except picking up their bedrooms were basically done, or mostly done in the case of the laundry. She was about to suggest putting on some more clothes when Shannon happily declared, "Well, I guess it's time to go help Big Brother with the hedges! Let's bring out some lemonade, too!" She bounced over to the refrigerator and pulled out a tray, with a full pitcher and three glasses, which she must have prepared ahead of time. She thrust it into Abby's hands, then pushed her shoulders from behind, directing her to the sliding glass doors that led outside.
Abigail whimpered as she stepped onto the patio, feeling the warm sun on her exposed nipples for the first time she could recall, not counting any that happened to shine in through a window. She raised the tray higher, doing what she could to conceal her breasts, and realized with consternation that they'd apparently timed their exit perfectly, as Jacob was parking the mower back in the garden shed. He emerged just as the two girls walked up, and he stopped in his tracks in shock.
Like his sisters, Jake was topless, showing off his lean torso. His shorts covered quite a bit more of his lower body than their thongs, but they didn't hide the boner that immediately popped up at the sight of the girls.
"What?" Jacob said dully, apparently unable to utter anything more complex or intelligent.
"We brought something to help you cool off!" Shannon chirped, taking the pitcher and a glass from the tray, not coincidentally exposing more of Abby's pale breasts, which were currently rather pink from a blush that had spread down from her face, making her look almost sunburned. Jake's eyes immediately darted to her chest, while she tried to rotate the tray so the two remaining glasses would preserve some shred of modesty.
"Let's go sit on the patio!" the foundling suggested, pressing the glass into her brother's unresisting hand. Abby turned around immediately and started walking as quickly as she could toward the plastic table and chairs on their deck, relieved to conceal her breasts again, although she could almost feel her brother's eyes on her ass. She was a little surprised to see a small stack of beach towels sitting there, which she assumed must have been Shannon's doing. She stood staring at them, uncertain how to act.
When her siblings arrived, Shannon took the tray and set it on the table; although Abby wanted to use her freed hands to cover herself, they fell awkwardly to her sides instead, and she fidgeted nervously, trying to avoid looking at her brother, knowing he was looking at her. Their sister started pouring out two more glasses while she said, "Go ahead and put some towels on the chairs, then take off the rest of your clothes!"
The two natural siblings started obeying her suggestion automatically, but once the seats were covered, they both paused with their hands poised to shuck off their bottoms, hesitant to completely follow the command. Done with serving the lemonade, Shannon quickly pushed her own thong to the ground and simply said, "Strip!" before seating herself.
With sudden alacrity, Abby and Jake both removed their only articles of clothing, fully exposing themselves to one another for the first time as adults. Abigail squirmed even more, finding her eyes drawn to her brother's cock against her will. She was surprised to see that it was a very nice one, although so rampantly erect that it looked rather painful, with the head almost as purple as a plum. She wasn't sure how it measured up, but thought it was a little above average in size and well above average by her personal sense of the aesthetic, imagining that it would fit very comfortably inside her. The realization of where her mind was wandering caused a surge of horror, and Abby bit her lower lip very hard as she quickly slid into a seat.
