Author's Note: While this story and its various chapters are primarily incest themed, it will often contain things such as excessive cum, anal play/pegging, and whatever else amuses me at the time. Reader discretion is advised.

Jaime woke up to the feeling of his sister bouncing on his cock. Her tight pussy embraced and massaged him into consciousness. His first sight of the day was her beaming smile and jiggling breasts as she rammed herself onto him over and over.
"Mmm," Jaime moaned. "Good morning to me."
Emily giggled. "I knew you'd enjoy it. For some reason you seem to prefer waking up inside me, rather than vice versa."
"Yeah. Weird."
Jaime grabbed his sister's magnificent tits and gave them a proper good-morning fondling. He sucked each of her nipples in turn, then gave them each an extra kiss.
"Ooh, that's nice," Emily cooed. "Do it some more."
"Are you sure? You wouldn't rather something a little more than that?"
"Like what?"
"Liiike, say... flipping you over and pounding your tight little sister-cunt until you pass out from incest overload?"
Emily kissed her brother fiercely and squeezed her pussy extra tightly around his cock. She couldn't resist him when he said such romantic things.
Jaime rolled him and Emily over so that he was on top of her. She clung to him and didn't let their lips separate, or his penis exit her. He began thrusting into her with the savage tenderness that he knew his sister loved. He ravaged her mercilessly, and soon she broke out in a chain of brother-induced orgasms.
Jaime watched his sister's beautiful face as he fucked her right to the breaking point. Her eyes rolled back in uncontained pleasure, and her smile was wide and directionless. It was amazing what his pure love and a little sexual brutality could do to her. So long as he kept pounding her, she'd stay in mindless sister-slut mode practically forever.
Hours later, after delivering countless orgasms to his sister, Jaime felt the need to cum. He pulled his cock out of Emily's pussy and shoved it down her throat instead. It was so lubed up with her juices that burying it in her mouth was smooth and frictionless.
"Time for breakfast, Em."
Emily looked up at Jaime with adoring eyes. She tingled in anticipation of being filled up with brother-cum. It was her favouritest thing in the whole world, other than being filled up with Jaime's wonderful cock.
A torrent of cum gushed directly into Emily's tummy. She grabbed Jaime's butt and held him firmly embedded down her throat as she swallowed the entirety of his huge, sexy load. Her belly swelled and bulged out at the sheer quantity of it all. She was well used to the feeling, but still savoured every second of being stretched out by an impossible quantity of semen.
Jaime pulled out of Emily's throat and let her start breathing again. He lay down next to her and put his hand on her cum-swollen tummy. Her skin was so supple and warm to the touch.
"It almost looks like you're pregnant, you know," Jaime said.
Emily giggled. "Pregnant with a brother-cum baby," she said happily. "The best kind of pregnant."
The siblings cuddled for a while. They ran their hands over each other's naked bodies, and it didn't take long for them to get horny again.
"We should get up," Emily said regretfully. "We have to get ready for school."
"School? I thought it was still the weekend."
"It should be. But time moves at the speed of plot, so today's a school day."
"I see. This shit's complicated, huh?"
"Little bit, yeah."
Emily padded naked down the hall to her room. She intended to get dressed, but a thought occurred to her before she quite made it there. Her mom's door was closed, and it was possible that she and Aunt Krissy were still asleep. She couldn't resist checking on them.
Emily carefully pushed the door open without making a sound. Sure enough, both her mommy and aunt/daddy were still sound asleep. Christine lay nearer with Krissy spooned right up behind her. Their sisterly similar faces wore blissful, angelic expressions in their unconscious states.
After just watching her parents sleep for a moment, Emily crept closer still. She used all of her ninja skills to approach and pull back the covers without being detected. She had considered playing with Krissy's cock a little while she slept, just for fun, but that turned out to be unfeasible. Krissy had her penis lodged firmly in Christine's butt while they sleepily spooned. There was no way to get at it without waking them up.
It was quite a beautiful sight to Emily. Her sexy-ass parents were all cuddled up in an intensely arousing and romantic position. She took it all in, then lovingly pulled their covers back up and tucked them in snugly. She kissed them each on the forehead, then left the room. She still had school to get ready for.

Exiting the bus at Over Eighteen School was a surreal experience for Jaime that morning. He'd been going there for a week now, and even though some crazy things had happened in that time, they had basically all been sexy rather than violent. This time was different.
The field beside the school was filled with hot girls and flashing blades. It was a medieval melee of a sort Jaime had never actually witnessed before. Even more confusing, most of the other arriving students didn't seem at all surprised. Some of them stopped to watch, but more of them simply carried on.
"Em? What the hell's going on?"
"Hm? Oh, the gang fight?"
"Is that what that is?"
"Well, yeah. What did you think it was? Some sort of modern art?"
Jaime walked closer and Emily followed along. "They're swinging swords at each other."
"Mmhm. Just blowing off some steam. It's good to get it out of their systems. Keeps things more orderly the rest of the time."
