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.
*****
Emily had a very restful sleep. She spent the whole night spooned up behind her brother with her strapon filling his ass. It was a comfortable, soothing position for her, and helped melt away the effects of recent over-exertion.
Her body came awake in sections, rather than all at once. First her arms tightened around Jaime's chest, and she pressed her breasts against his back. Then her hips began rocking in slow, lazy circles, pistoning her fake cock back and forth inside her brother's butthole. She nuzzled at his neck as her eyes opened and she became fully aware of her surroundings.
Emily smiled to herself. She got to wake up naked in bed with the love of her life, already in the midst of fucking him. Even better, it was finally the weekend and they didn't have to get up for school. In theory, she could spend all day in bed pounding her brother's ass. Life couldn't get much sweeter than that.
Jaime moaned in his sleep as Emily gradually fucked him harder. She grabbed his cock and gently stroked him while she explored his anal cavity. He leaked copious precum as she found all his most sensitive spots, inside and out.
Jaime finally woke up when Emily rolled him onto his stomach and really started ramming him. His butthole was getting viciously slain by his adoring sister first thing in the morning. Typical.
"God, Em, you... hngg... didn't even let me... hngg... wake up first," Jaime said.
"I can't help that you're so much fun to molest in your sleep."
"Well, I'm glad I... hngg... amuse you so."
"Mmm, you really do. You've got such a hot little body. I'm so lucky you're my brother."
Emily held Jaime's hips and maintained a deliberate, rhythmic pattern of hard thrusts. She delighted in the way his body reacted every time she pulled almost all the way out, then slammed her way back in. His tight butthole gripped the invading dildo and really made her work for it.
Jaime adjusted the pillow under his head. The sun was just creeping high enough in the sky to come flooding through Emily's bedroom window. When his eyes fell on her mirror, Jaime had a clear view of himself and his sister locked in their incestuous, anal embrace. She had such an aura of radiance and life for first thing in the morning. He still looked half asleep.
Eventually Emily switched to a gentler, smoother stroke. It was far less jolting to Jaime's body than the hard thrusts, and the sensual rhythm lulled him back to sleep. She giggled happily when she realized that her softer ass-fucking could actually relax him that much. She leaned down to kiss his ear.
"My little butt slut," she whispered adoringly.
After some more tender, lullaby butt-fucking, Emily rolled her brother onto his back. She propped his hips up with a pillow, then kept right on sliding in and out of his rear entrance. She hummed a sleepy melody to help keep him in dream land while she violated his unconscious body.
It took a fair amount of delicate work, but Emily got her result. Jaime's internal areas could only take so much loving stimulation before he exploded. His cock twitched a few times in warning, then burst into a fountain of cum that showered both of them. Emily squealed in delight and fucked her brother harder to pump every possible ounce of liquid out of him.
Jaime woke up in a panic with his mouth and nose blocked, restricting his airways. Emily was enthusiastically pounding him while cum billowed all around. He swiped at his mouth to try and clear it, but cum was everywhere and he couldn't make any real progress.
"Oooh, Jai," Emily cooed. "That was a good one."
She squished down on top of him, pressing their slimy bodies together. She kissed and licked at his lips, cheeks, and forehead like a good little cum-slut until his face was somewhat cleared.
"Fuck's sake, Em."
Emily pouted and batted her eyes, though the effect was marred when her eyelids kept sticking together. "You don't like your horny sister all battered in your cum?" she asked innocently.
"No, I like that part. But I'm all covered too. And the bed... goddamn we're going through mattresses. Mom's gonna be pissed."
"Serves her right, passing on her pervy incest genes to us the way she did."
"That's one way to look at it."
Emily was already lapping at his neck. She flicked her nimble, kitten-like tongue over her brother's sticky flesh, gathering up all his tasty cum. Usually she didn't get to taste much of it, since it got shoved down her throat in such vast quantities. This time she got to savour every little bit.
The impromptu tongue-bath continued down over Jaime's chest and tummy. Emily put special care into his cock when she got that far. She licked every single inch of it two or three times over. The coating of semen was replaced with a lavish sheen of her saliva, and a few thick strings of spit stretched between her lips and his dick when she pulled back to get a breath.
"Ok, Em. We need to get cleaned up."
Emily shook her head. "Uh uh. I'm not even hardly full yet."
She sucked one of her brother's balls, then the other into her mouth. She delighted in being able to get cum from their outside instead of their insides.
Jaime tried to push his sister's head away from his crotch. Both her hair and his hand were saturated, and it was hard to get much of a grip. Even when he got a hold of her chin and lifted her face away from his cock, she simply sucked at his cum infused fingers instead.
"Seriously. I'm starting to stick to the bed, and if I don't move I'm going to be glued in place pretty soon. Besides, I'm actually starving. It feels like I'm constantly cumming my body weight, and not eating much of anything to replace it."
Emily tilted her head. She scooped a trail of cum off her tummy and extended it to her brother. "Wanna try some?"
Jaime rolled his eyes. "No, Em. You're the cum-slut, not me."
"Only 'cause you never tried. You might like it."
In spite of her argument, Emily was already lapping at the pool of cum in her hand. No point wasting it if her brother wasn't going to eat it.
There was a loud slurping and squelching sound as Jaime sat up. He was soggy and dripping everywhere, and really badly needed a shower. He pulled his legs free, and managed to stand up.
"Come on, shower time," he said.
Emily was still scooping cum off herself. "Sure sure. Right behind you."

There was no sign of anyone else in the house being up yet. Even after a long, steamy shower session and the time it took to clean up Emily's room, the siblings effectively had the place to themselves. They opted not to dress for breakfast. Why put clothes on when you could be naked instead?
Emily, having swallowed a great deal of semen already, wasn't particularly hungry. Jaime was ready to eat just about anything. He went straight for the refrigerator, only to be shoved out of the way by his sister.
"Hey, I wanted to see what's in there," he said.
"Don't worry, I'll make something for you," Emily replied. "You've been feeding me such lovely breakfasts lately. I feel bad not being able to reciprocate."
"Aw, you don't have to worry about that. I love filling your tummy up with cum almost as much as you enjoy swallowing it."
"Mmm, I know. But still."
