Author's Note: All characters in this story are over the age of 18. This story follows on directly from Ch. 02 so I recommend going back and reading the rest of the series if you haven't already. Enjoy!
"You enjoyed the last creampie so much," Lily said wickedly, "so I made you another one..."
Wiping the tears from her eyes, Dani watched in disgust as a glob of her brother's jizz slowly leaked from Lily's well-used hole.
"If you want me to delete those pictures, you better not waste a drop."
After everything she had been through, everything she had done, what more was one final humiliation? Dani knew she had to see it through.
As Dani shuffled towards the edge of her bed she was struck by the thick aroma of sex. She recognised the musky scent of Mike's special ingredient but the sweet fragrance of her sister's juice was new. Despite her misery, and her belly full of cum, Dani couldn't help but salivate as her siblings combined juices oozed down Lily's inner lips and pooled on the tip of her clit.
"Better hurry or..."
Lily's next words were lost in a soft moan as she felt Dani's tongue lapping gently against her engorged clit. Her pussy clenched and forced out another glob of Mike's cum, which streamed straight into Dani's waiting mouth.
"Fresh cream always tastes better," Lily taunted, "wouldn't you say, Dani?"
Dani pulled her wet face away from Lily's pussy and watched in amazement as more cum poured out of her hole.
"I want to see how much you enjoy it."
Lily rolled onto her back, grabbed Dani by the hair, and forced her mouth back against her gushing cunt.
Dani ran her tongue from top to bottom, side to side, trying to pretend it wasn't her sister's pussy she was eating but savouring the blend of sibling jizz nonetheless.
Lily locked her trembling legs around Dani's head as the older girl's tongue worked its way inside her dripping hole. Gasping, Lily instinctively thrust into Dani and was rewarded by her sister's tongue burrowing deeper into her spasming tunnel. Lily could feel it swirling inside her as Dani sought out the reservoir of their brother's cream.
Gasping for breath, Dani gawped at the copious stream of milky fluid pouring from Lily's quivering pussy. It flowed out of her and pooled on her still slightly gaped arsehole.
"Every...drop..." Lily stammered, rubbing her clit with one hand and applying pressure to her abdomen with the other to force out even more delicious brother-cum.
Clenching her eyes tightly shut, Dani attacked Lily's arsehole with enthusiasm. Her sister's puckered hole clamped down on Dani's tongue, winking open and closed with each contraction of Lily's impending orgasm.
"What's...what's hap...happening..?"
Peaks of pleasure, each more intense than the last, shook Lily's body. Furiously rubbing her clit, Lily reached out for Dani's hair and mashed her face against her cum splattered pussy.
"Dani...Dani...Dani!" A fountain of cum suddenly squirted over Dani's face, drenching her from point blank range, as Lily climaxed uncontrollably. Freed from her sister's grip, Dani recoiled in shock and took a second jet straight into her open mouth.
"Strawberries." Dani mused, as she watched her sister coming down from her orgasm.
Lily shivered as her hand brushed against her soaked pussy. "What...was that?"
Lily asked, her cockiness forgotten as she gazed awestruck at her sister's dripping face. "Did I do...that?"
"Happy Birthday?" Dani offered, at a loss for words.
Basking in the afterglow of her orgasm, Lily rolled onto her side and hugged her knees to her chest.
"So you'll delete the pictures?" Dani pleaded.
"Pictures?"
"Earth to Lily! The pictures!"
"Oh, right, yeah," Lily mumbled, "I guess this makes us even."
"Even?" Dani thought, "You must be mad."

"M.A.D. Can anyone tell me what it stands for?"
Professor Jones looked around the lecture hall packed with hungover and disinterested students. Even by their exceptionally low standards, his Political Theory 101 class seemed preoccupied today; passing notes and whispering in a near-constant murmur that irked the professor.
"Monday lectures," he sighed inwardly, "what a waste of time."
A familiar hand shot up.
"Yes, Ms. Matherson?"
"Mutually assured destruction, sir."
"Correct...again. Would anyone ELSE care to explain the concept?"
Professor Jones pointedly ignored Beckie Matherson's skyward hand as he scanned the room. The students were definitely distracted, checking phones and throwing glances at the lonely girl hunched low on the back row. He tried to remember the girl's name. Dani, was it?
"Go on then, Ms Matherson."
"It's a doctrine of military strategy which posits that a full-scale use of nuclear weapons by an attacker on a nuclear-armed defender with second-strike capabilities would cause the complete destruction of both the attacker and the defender."
"Textbook," Professor Jones confirmed with a generous hint of irony, "or for the laymen amongst us - it's a stalemate. One side doesn't attack the other to avoid triggering their own destruction. But there's a problem..."
"M.A.D relies on rational actors!" Beckie Matherson blurted, totally oblivious to the student leaning over her shoulder to look at something on her neighbour's phone.
"Exactly, Ms Matherson. What deterrent is destruction to an enemy who cares not for death? To the insane and the desperate? Mutually assured destruction is only effective as long as both dogs are still in the fight."
--
Dani hustled out of the lecture hall with the bell still ringing in her ears. She clutched her books to her chest and kept her head low, trying fruitlessly to ignore the pointed stares and muffled laughter as she skipped down the steps past her classmates.
"Dani, wait up!"
Dani recognised the tall, dark boy from college football games but he'd never spoken a word to Dani before.
"Huh...hi Anthony."
"Where are you heading?"
"Umm...cheer,"
"Oh right...of course...you cheer?"
"Only at all your games this year."
"No shit!"
Dani took offence at his heartfelt surprise. "I'm kind of in a hurry, actually."
"How about tonight? Do you have plans later?"
This stopped Dani in her tracks. She studied Anthony suspiciously, waiting for a punchline that never came.
"I've got a busy...I'm thing," Dani blurted as she dashed away from the bemused football star, "sorry!"
--
Dani didn't think the day could get any weirder but, as she opened her locker in the girls changing room, she conceded that she might have been premature in that assessment.
A pink dildo stuck to the back of her locker door slapped her across the face as the door swung open. The huge, wobbling length of silicone ricocheted comically and, before Dani could snap out of her shock, thumped into her other cheek.
Laughter echoed around the changing room as the half-dressed cheer squad watched Dani unsuccessfully attempt to wrench the suction-cup from the locker door.
"I hope it's big enough," the cheer captain, Jenny, called out, "I know it's not up to your usual standards!"
Dani was left clueless as the cheer squad emptied out of the changing room. Still blushing, she slammed the locker door closed.
"Frick!" Dani screamed, as a mousy girl with thick, coke-bottle glasses was revealed behind the locker door.
"Sorry!" The girl squeaked, "I didn't mean to scare you."
"It's fine, Luna. I'm just a little on edge. It's been a weird day."
"I know the feeling. There was pickle in my cereal again this morning."
