It started like any other day that summer: Jack's alarm pulled him from slumber at 7 a.m. sharp., and after muttering an obscenity, grasping to find the snooze button, and rolling back into his sheets, Jack promptly fell back asleep.
Several snoozes and mutterings later, he shuffled into the kitchen to greet his parents. Jack knew if he managed to croak a "good morning" to them before 07:30, he wouldn't get a nagging about "sleeping the day away." After some fussing over his appearance, cleanliness, and/or demeanor (Jack's still-sluggish brain had a tendency to let these words float in one ear and out the other), his loving parents gave him his list of duties for the day: some light chores, grocery shopping, and preparing dinner for them and his younger sister, per usual. Jack was set to start his freshman year of college in the fall, and in the meantime his parents were letting him stay at home rent free -- as long as he helped around the house and completed the tasks they gave him.
Having stayed up until 4 a.m. playing video games, Jack couldn't wait to get back to bed -- and so as soon as his parents had left and closed the front door, he was lumbering toward his room. Turning the hallway corner, however, he barely avoided colliding with his sister going the opposite direction. "Watch it, sleepyhead!" Anna giggled.
"Sohry, m'bad" Jack mumbled as he shuffled past. Anna had probably been up since 6, and turned to give him a knowing smirk as he closed the door to his bedroom.

Anna giggled to herself again about Jack's disheveled appearance as she turned back toward the living room, leaving her brother to his slumber. She had better things to do than bother him right now -- like studying. Despite still being in high school, she had enrolled in a summer course on genetics with a local community college, feeding her interest in perhaps someday being a doctor.
Anna didn't mind at all that her big brother was staying at home for what might be her last summer of "freedom" before she graduated high school and headed off to university. Only one year apart, they had had their share of arguments and sibling rivalry growing up, but there was playfulness and laughter too, especially in the past couple of years. These days, their friendship was a source of joy for both of them, and Anna was actually relieved that they were home together for one last summer.

Jack woke again with a start around noon. Daylight streamed into his eyes as he blinked several times, leaned on his arm, and slowly re-familiarized himself with consciousness. Thankfully, he was feeling human again. Padding back out toward the kitchen, he saw Anna curled up on the couch in the living room, watching some corny rom-com while working on homework. She smiled and then stuck out her tongue when she saw him, and he promptly returned the gesture.
What a nerd,
they thought almost simultaneously.
Jack slapped together a PB&J for his breakfast/lunch and hungrily snatched a bite of it as he walked back to the living room. Standing next to the couch where Anna was sitting, he chewed and watched the characters on the screen for a few moments before offering an observation: "This show is total mush."
"Your face is mush. Also, it's a movie."
"You didn't deny it's mush though," he grinned.
She just smiled, still scanning for information from the textbook in her lap. "Mush can be good sometimes," she replied.
"Mmmkay." The last of his sandwich in his mouth, Jack turned back toward the kitchen to start his day. He looked forward to poking more fun at his sister later, but in the meantime, he had to work.

Jack was kept busy most of the rest of the afternoon and early evening getting groceries and working around the house, so it wasn't until after dinner that he was able to escape back to his room for some alone time. He was at his desk booting up a 4X game on his PC when he heard a soft knock on his door. "It's open!" he chirped, and turned to see Anna poke her head into the room, smiling sheepishly. It was one of Anna's guilty pleasures to occasionally sit and watch him play video games; her favorites were the thrilling, action-packed types where fighting (sometimes while on the brink of death) was required to reach the next save point. Jack grinned and started switching to such a game for her enjoyment.
"No, that's okay -- I'm not sure how long I'll be able to stay awake anyway," she yawned.
"Okayyy, if you're sure..." Jack flipped back to the slower-paced game. "I'm currently fighting for land in Siberia, so this might get tedious..."
Jack turned his head again when Anna didn't reply, glimpsing for a moment his sister in her pj's as she crawled onto his bed. Curious, he swiveled his chair further to watch -- usually she just sat on a chair next to him to watch him play.
Anna liked wearing a loose t-shirt and a cozy pair of panties at night. As she moved onto his bed on all fours, Jack saw that tonight, his sister's panties had flowers on them. He jerked his gaze away -- he hadn't meant to look at his sister's barely covered butt, but in his mind's eye he couldn't help but appreciate the view he had gotten. He was only human, and his sister was no longer the bratty little girl he had grown up with, but instead a fit 18-year-old woman. And, well, still just a little bratty...
Drifting in thought, he found himself observing his sister again. Thankfully her legs and bottom were mostly covered by his sheets now, and she was just rearranging his pillows on her knees. As she bent to reach a pillow on the other side of the bed, however, her panty-covered butt (and crotch) rose from the bed, his blankets falling from her waist, just three feet away, pointing directly at him... Jack gulped. And then, he could see through his sister's slightly parted legs, as her baggy t-shirt opened to provide a view of the undersides of her breasts...
Jack guiltily grabbed his phone off his desk, tapping randomly on the home screen and pretending to be occupied. Embarrassingly, and in spite of his good intentions, that exposed view of his little sister's body would now be lodged inside of his brain forever.
He managed to let Anna finish whatever she was doing unmolested, and then looked up a moment after she stopped moving around. Anna smiled at him, her face and its goofy grin now the only things not hidden beneath his covers. He shook his head and chuckled nervously, then quickly swiveled his chair back to his screen. "You planning on taking over my bed, A-train?"
Anna yawned again and then offered sleepily, "I spilled ice cream on my bedsheets, and I don't want to bother cleaning them tonight... is it okay if we just share your bed for tonight?"
"Ugh. Fiiine." Jack smiled to himself with an exaggerated sigh and mock frustration. But both siblings knew that the arrangement would be fine; Jack had a queen bed, after all, so there was plenty of room for the two of them.
