A dramatic peal of thunder cracked over the skies and the skies opened up into a deluge of rain. Hard, heavy droplets of water bashed on the roof of the laboratory where Alchemist Cookie toiled away by candlelight. Beakers bubbled, flasks fizzed and cauldrons churnd. She passed fluids between vials at a breakneck pace, tossing strange swirling concoctions around with practiced skill and expertly aerating them in the process. All her efforts over the long, sleepless night slowly boiled down to a single batch, a single potion, a single bottle.
 
"My masterpiece!" Alchemist shouted, holding the potion aloft.
 
A crack of lightning illuminated her greatest creation yet: A purple potion so rich and beautiful in its hue that it seemed more purple than purple itself. It was so glorious that Alchemist was having trouble pulling her eyes away from it. It was so miraculous that she thought it couldn't truly be real, and that peeling her eyes away from it would cause the illusion to vanish.
 
"It's perfect, no, it's beyond perfect." She said, "I've truly done it! I can't afford to wait any longer!"
 
Alchemist only admired her creation for a moment longer before slamming a cork into the bottle. She was careful to completely secure it, not allowing a droplet of her creation to escape. Then, with her creation clenched in her hand, she slipped out of the laboratory and down the stone halls of the castle to the one room she would never normally tread: Her brother's. She slammed her free fist against the large oaken door and shouted,
 
"Brother! Brother open the door this instant! Are you sleeping?!"
 
Though she knew the answer, as her brother was rarely caught doing anything OTHER than sleeping. Without waiting a moment more, Alchemist put her foot to the door instead of her fist and kicked it open. Her brother, useless as always, was snoring away in his casket. Alchemist crept up to his bed, as carefully as could be, then leaned over and whispered to him,
 
"Brother? Dearest brother?" She smiled warmly down at him, then suddenly reeled back and kicked his coffin over, "WAKE UP YOU LOUT!"
 
Vampire tumbled out of his casket and onto the cold stones of his bedroom floor, gasping as he was jolted from his delightful slumber. He looked around, nearly as confused as he was upset. Alchemist stepped in front of her confounded brother and glared down at him, giving him something to focus on. Eventually Vampire put two and two together.
 
"Sister! Why did you wake me? I was having the most wonderful dream." He moaned.
 
Alchemist rolled her eyes, "Dreams! Hah! What I've got in my hands is beyond your wildest dreams!"
 
"If it's not wine, I'm not interested," Vampire said, noticing a bottle on the floor that, disappointingly, contained no red wine for him.
 
"It's better than wine! Look, come close brother; behold my genius!" Alchemist said, then gripped the cork between her fingers, "And prepare to be amazed."
 
The cork popped free from the bottle and it was followed by a wave of scrumptious smell. The aroma rolling off of the bubbling concoction was beyond sweet. It was more grape than grape itself. One whiff had Vampire wiping the drool from his fangs. He could barely think with the allure of the potion taking control of him.
 
"What... what is it?" He asked, reaching out for it.
 
Alchemist pulled the bottle away and scoffed, "Ah ah! Don't touch. Allow me to demonstrate."
 
Alchemist held the potion up, then titled it towards her body. With machine-like precision her hand lowered the lip of the bottle lower and lower, until just one droplet of the potion fell from the rim and onto her cheek. She immediately corked the bottle back up and patted the droplet into her face.
 
"Well, is it not exquisite?" She asked.
 
"I don't understand," Vampire said, narrowing his eyes, "Did you--"
 
Alchemist cut him off, "Make the world's most delicious perfume? Yes! I did! This overwhelmingly fresh, grapey aroma is the most potent, most pure, most delicious smell in the world. What do you think, brother?"
 
Vampire leaned in and sniffed his sister. Then he sniffed her again. That aroma was unlike anything he'd smelled before. It was more robust than his finest wines. He needed to taste it, and the easiest way to do so was right in front of him. He lashed his tongue out, licking up the side of Alchemist's cheek. She gasped and drew back.
 
"Brother! That's--"
 
"Delicious," Vampire said, wiping his lips, "Absolutely scrumptious. I need more of that sweet grape flavor..."
 
Alchemist suddenly felt very small, very afraid. She pulled away, holding her potion away from him. She wouldn't let him get her greatest creation. Unfortunately, that wasn't his aim. He lunged at her like a wolf, his mouth opened wide. Alchemist had only a moment to scream before her face was stuffed into her brother's hungry gullet. She panicked, dropping her potion into a pile of discarded wine bottles. She tried to push back against Vampire's mouth, but her brother was supernaturally strong.
 
Vampire swallowed hard, taking her body into his throat up. Alchemist was up to her hips in Vampire's throat, and she could do nothing but weakly kick her little legs in the air. One more hard gulp and those too disappeared into his throat. Vampire closed his mouth, sealing Alchemist inside of his body as his gullet worked her down into the cramped confines of his stomach. For poor little Alchemist, her world had become a dark abyss of hot, wet, wine-stinking disgust. But for Vampire, it had been a decent meal.
 
"Urp, not bad Sister," He said, "Not bad at all. Though it could certainly use a chaser. Let's see here..."
 
Vampire sifted through the wine bottles that laid all around his bedroom, not finding a single one that had any of his sweet red lifeblood in them. Fortunately he quickly found something even better: a bottle containing that impossibly purple nectar that had driven him so wild with hunger.
 
"Ahaha! What could be more poetic?"
 
He dug his fang into the cork and popped it off, spitting it into a pile of similarly discarded wine corks. He swallowed the whole potion in just a few hard gulps, finding it every bit as delicious as he'd hoped it would be. It made the perfect pairing to his scrumptious sister. Inside of his stomach, Alchemist got to taste a bit of insult to go with her injury as all her hard work was poured on her head and would serve as a marinade as she was churned by her brother into a cookie gut stew.
 
Vampire belched, wiped his lips, and held his sloshing belly. He was satiated, and there was nothing he loved more than to follow up a satisfying meal with a nap. He propped up his casket again, laid down in it and neglected the lid, as he doubted it would fit over his distended gut. He drifted off into a blissful sleep, allowing his body full agency in disposing of his rude little sister.
 
Some hours later, Vampire was roused from his sleep by a sudden urge: a desperate need to piss. He hopped out of his casket and looked around for something suitable to empty his bloated bladder into, but he could tell this would need more than just an empty bottle. That's when he spotted it: a cask that had once been totally full of red wine (Which he drained all in one night not too long ago).
 
"Good enough!" Vampire said, flipping the lid off the barrel and freeing his cock from his trousers.
 
He lazily aimed his dick over the rim and sighed, releasing the full load of his bladder in one long, blissful stream. He was so lost in the pleasure of emptying out that he didn't notice just how long he'd been urinating until he saw that he had, miraculously, filled the entire barrel with sour-smelling urine.
 
"Gracious, I don't suppose that's all that's left of you, sister." Vampire said, then leaned over and sniffed his bladder brew, "Eugh. It certainly smells as sour as you. I think this batch needs to ferment a bit longer! Ha!"
 
Vampire tossed the lid back on what remained of his nuisance of a sister and returned to his coffin. Hopefully now he could finally rest in peace.
