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 and Emily had been caught. They'd finished having sex for the very first time, then walked straight into their older sister Lilith. She was smirking triumphantly at them with her arms folded and her eyebrow raised, practically daring them to tell her it wasn't what it looked like.
"It's not what it looks like," Jaime said desperately.
Lilith eyed him up and down, then did the same to Emily. Both of them were completely naked, and Emily was covered in gallons of her brother's cum. Emily was a little quicker than her brother in admitting defeat.
"Ok, it's exactly what it looks like," she said.
"No shit," said Lilith. "I'm impressed, little bro. That's quite a load you gave your sister."
"Yeah, I was wondering about that," said Jaime. "Is that normal? Because it doesn't seem normal."
The girls ignored him. They were busy staring each other down. Lilith had a significant advantage because not only did she hold the moral high ground, but cum kept dripping in Emily's eyes.
"Are you going to tell?" Emily finally asked.
Lilith stayed silent for a moment before answering just to make her sister squirm. "No. I don't think so. You guys'd get in a little too much trouble for it to be funny."
"Actually," said Jaime. "We shouldn't really get in too much trouble. We looked it up. It's not illegal if we really, really want to do it."
"Pff, I know that," said Lilith. "I have a pretty good handle on the Littown legal code, thank you very much. I need to for my job."
"What, bartending?"
"She runs a strip club," Emily said.
"But she always said she was bartending at night, and that's why...." Jaime paused and examined Lilith critically. "Oh, you just didn't want Mom to know you're a stripper. That makes sense."
"Hey." Lilith jabbed a finger at her brother's chest. "I'm not a stripper. I run a strip club. There's a difference."
Jaime took a meek step back. "Sorry," he mumbled.
"You better be." Lilith pointed back and forth between Jaime and Emily. "And both of you owe me for shutting up about this. I hope you know that."
"Yeah, we got it," Emily said. "Now if you'll excuse me, I really need to get this stuff off me before it hardens into a protective shell."
Emily finally made it to the bathroom and started the shower running. Jaime remained out in the hallway, unsure if he was dismissed or not. Lilith's expression softened slightly at his somewhat pathetic nervousness.
"Hey, by the way, congrats on the sex marathon, Jai," she said. "Very nice for your first time. And with your own sister no less."
"Uh... thanks?"
"Oh yeah, and I got you something too. Hang on a sec." Lilith vanished into her room, then came right back with a small bag in her hand. "Sorry I didn't wrap it or anything, but happy birthday anyway."
Jaime was both relieved that the blackmail portion of the night was over, and curious as to what Lilith could have gotten him. He reached into the bag and pulled out....
"Lil?"
"Yeah?"
"What's this?"
"A butt plug. Duh. Says right on the package."
That's what Jaime thought it was. He'd just assumed he must have been terribly wrong about what he was seeing.
"Why did you get me a butt plug? What am I supposed to do with it?"
"Well, traditionally one shoves it up one's butt. You could try that if you want. Or maybe put it up Emily's butt if you guys want, since you're an item now and all." Lilith shrugged. "It's yours, dude. Do whatever you want. Shove it in the back of a drawer and forget it if you so choose. I just thought it'd be nice to have to option to experiment if you wanted to."
"Does this have anything to do with you getting Em a vibrator for her birthday? Is this going to be a theme?"
"Maaaybe. Seemed a little silly to get you a vibrator too, though it would have been cute for you guys to match. Maybe if I get her a butt plug too...." Lilith yawned and stretched. "Anyway, long day. Gonna go fall unconscious for several hours."
"Good night, Lil. And... thanks."
Lilith gave her brother a big hug, seemingly unconcerned by his nudity. "No problem, bro. Oh, and there's a little thing of lube in there too. Lemme know if you need to be hooked up with some more."
She winked, then sauntered away terribly pleased with herself. Jaime was left naked and holding a sex toy he'd never so much as contemplated owning. He tossed the bag in his room, then sought out the reassuring company of his new incestuous lover.
Emily had made a good start on cleaning herself up, but was still quite a mess. Jaime got in the shower with her and helped her wash off. This meant that he got to run his hands all over his sister's wet, slippery body. His cock kept poking Emily, or getting squished between their bodies. They were both getting super horny again, but somehow managed to get Emily all cleaned up before they acted on their feelings.
"I know we just had sex for literal hours," Emily said, looking deep into her brother's eyes as water cascaded around them. "But I really want to feel you inside me again like right now."
"I love you and your hot body so much," Jaime said.
They kissed hungrily, their hands unreservedly groping around for anything and everything. Emily then spun around and braced herself against the shower wall. Jaime took careful aim and shoved his cock hard inside her tight, needy pussy from behind. Once buried, he held still for a moment to savour the sublime, heavenly experience of being so fully connected to his sister; the girl he loved with all his heart and penis.
