Author's Note: Anyone still reading this series knows what's up. Still, be warned this story contains lots of fetish stuff other than incest, and is also a tad silly.

Jaime woke to the sounds of giggles and shushing. More urgently, however, were the feelings of his throat and asshole being invaded and stretched out by big rubbery cocks.
"Oops, I think we woke him up," said Emily from above him. She burst into another giggling fit.
Lying on his back with a fake cock shoved in his mouth, Jaime couldn't really see much of what was happening. He mostly had a good view of Emily's butt as she face fucked him with her strapon.
"I told you we couldn't fuck him for long without waking him up," said Lilith from down by Jaime's ass.
"Well you never know," said Emily defensively. "I've been fucked in the butt for a while without waking up."
"Yes, but you're a total butt slut."
"So's Jai."
"Not like you, dear sister. No one's quite the slut you are."
Emily beamed proudly. "Aw, thanks, Lil. You're so sweet sometimes."
Jaime decided he better interject at this point. However, his mouth was pretty full.
"Whaaah uhuh mmmhhhyyuu?" he asked.
"Sorry, what?" Emily said. "I couldn't understand that."
Jaime tried again, but she didn't stop fucking his mouth long enough for him to pronounce even a single word.
"Em, darling," Lilith said while still casually pounding Jaime's butthole, "he can't talk with you shoving that dildo down his throat."
"Oh yeah." Emily smiled, undeterred. "That's ok. He doesn't need to talk."
"Uh owwwhhnn?" Jaime said.
Emily looked down at her brother between her legs with big, adoring eyes. "Happy ten-day anniversary, Jai! Me and Lil decided to do something special for you to celebrate. You just lie back and enjoy it."
"Uhhh..."
Lilith rolled her eyes. "I tried explaining that it's more a present for her than anything. But you know Em."
Jaime would have nodded if he had any control over his neck. He did, indeed, know Emily.
"Nonsense," said Emily. "He loves this. Don't you, Jai?"
"Ennhh," said Jaime noncommittally.
"There, see?" said Emily. "That was probably a yes."
"Whatever you say," said Lilith. "But you have to admit, he much prefers pounding your tight little butthole."
"Ooh, yeah he does," said Emily, who went all gooey at the thought of having her bottom well fucked by her beloved brother.
"And your cunt."
"Mmm, true."
"And your mouth."
Emily's eyes rolled back and she simply nodded agreement.
"And cumming all over you," Lilith continued.
"Yisss."
"Or, indeed, cumming inside you."
Emily exploded in a nice little orgasm as she imagined all the lovely activities her sister was listing. All of Jaime's favourite things happened to be on her list of favourite things too.
"Ok, well it's still top ten though," said Emily eventually, once she'd calmed down a bit.
"Ennhh," said Jaime, still noncommittal.
"Are you sure he doesn't just put up with it because he loves us?" Lilith asked. "Because that's where my bet is." She patted the bulge in Jaime's tummy that her strapon made when she buried it deep in his ass. "But he is such a lovely little brother butt slut."
"That he is," Emily concurred, ruffling Jaime's hair affectionately before grabbing his head with both hands and slamming his throat even more vigourously.
Jaime relaxed and let his sisters have their fun. Lilith was basically right, he didn't enjoy their attempt at making their dildos touch inside him nearly as much as they did, but he did like making them happy.
Plus the ten day anniversary of an incestuous relationship was one of the most important milestones. He loved Emily with most of his heart and all of his butt. If waking him up with some hardcore pegging action made her happy, then he was happy to be her fuck toy.
The girls fucked their sexy, naked brother until his internal organs were all bruised and he'd passed out a couple times. By then, Lilith, who was half demon, had fed on enough sexual energy to sate her lusts, and she decided Jaime could probably use a break as well.
"Alright, you two have fun," she said. "Happy anniversary, kiddos."
She gave Emily a deep, loving kiss, and would have done the same to Jaime if his mouth hadn't already been occupied. She settled for kissing him on the cheek, then left them alone.
Emily watched her big sister's ass sashay out the door, then turned back to Jaime. She decided that was probably enough throat fucking for now. For one thing, his eyes were beginning to roll back like he was going to pass out again.
Jaime coughed and spluttered and sucked in air greedily as Emily pulled out. She patted his head and waited for him to regain some of his breath.
He looked so adorable all naked and gasping and messy from saliva, precum, and pussy juices. She loved him so much it hurt.
"Lil's right, isn't she?" Emily said. "You like pounding me better than getting pounded, don't you?"
Jaime nodded. "Of course I do. Your tight little holes are made to be brother-fucked. Pounding any of them is literally the best thing in the world."
Emily's pussy gushed. She couldn't resist him when he was so sweet and romantic.
"Well, we're kind of running late for school, but it's our anniversary. It wouldn't be fair not to give you your favourite thing."
Emily slipped out of her strapons harness and got on her hands and knees. She reached back and slowly pulled out her butt plug. She gave it a kiss, then set it on her night stand where it could watch.
"I swear your plug's getting bigger," Jaime said, giving it a long glance as he knelt behind his sister.
"Yeah, it is," Emily confirmed. "They grow up so fast." She sighed wistfully. "Pretty soon he'll be too big to stay in his mommy's ass anymore. He'll go off in the world on his own, start a family, and never come visit my bum except on holidays."
