Obyzouth lay down flat on her back. The succubus spread her shapely legs and bared her dripping pussy to the three girls. "Come on, ladies!" she laughed flirtatiously. "My pussy is waiting for you. Let's form a lovely little chain of pleasure!"
Roxy nodded and walked over to the orange-skinned succubus. She lay down on her belly and began running her lips over Obyzouth's engorged pussy lips, earning an approving moan from the demoness.
"Oh, Baphomet!" Obyzouth groaned as Roxy pleasured her. "K-k-keep d-doing that!"
Valeria then slid her head underneath Roxy and began licking Roxy's own pussy. Roxy shivered with cold and arousal as she felt Valeria's chilly tongue brush over the exposed, erect clit.
Will hesitated before joining in on the orgy. She didn't feel entirely safe having sex with both a succubus and a vampire, no matter how attractive they were. Still, she didn't like the idea of her sister doing this unsupervised. Besides, Valeria von Karnstein DID have a really cute ass. Will sighed and lowered her lips to Valeria's pussy and began to lick, startling a bit at how cold the vampire girl's cunt was. The odd chill was off-putting at first, and yet it soon became... strangely enticing. Before long, Will was wildly lashing Valeria's snatch with her tongue as if she would die if she stopped, while her hand gripped the vampire's firm, tight ass.
The girls were now a four-person pussy-eating chain. Roxy felt like she was in Heaven as she ate Obyzouth's pussy and Valeria licked her own. Sex with a succubus was a unique experience. Roxy felt something deep within her being tugged on, like invisible hands were reaching into a deep part of her soul and groping something they found there... something sensitive She realized that this had to be Obyzouth harvesting portions of her life force like she'd said she would. It surprised Roxy just how arousing the experience was, like all of her spirit was crackling and tingling. This was actually making her soul feel the way her body did during orgasms!
Slowly, Roxy began to feel her soul hover outside her body as Obyzouth and Valeria continued to make love to her. She was too blissed out to care, however, even as her consciousness slowly began to fade away. Before long, a primordially powerful orgasm ripped through Roxy's body like a hurricane. It was the most intense climax she'd ever experienced; she felt as if she were beginning to fuse with Valeria and Obyzouth as every cell in her body caught fire. She could feel that Obyzouth's own climax as starting as well, both from the way the succubus's body was quaking and from the strange connection brought on by the orgasm. Suddenly, just as she was settling into the afterglow, Roxy's went completely limp and her mind fell into blackness.
Valeria stopped licking Roxy's pussy when she realized that she'd passed out. She pulled her head out from under her girlfriend. "Shit! She's out cold!"
Will yanked her tongue out of Valeria's vagina and glared at Obyzouth, a look of pure hatred in her eyes that could rival that of any demon. "You, two-faced, conniving demon bitch!" the monster hunter spat! "My sister trusted you! SHE TRUSTED YOU!!! And then you just... just fucking devour her like a hungry wolf that found a itself a juicy little lamb! Well, you're gonna fucking regret playing your sick games with Harker descendants!"
Will sprinted over to her backpack, grabbed a vial of holy water, and unscrewed its stopper before sloshing the contents all over Obyzouth. The succubus screamed in agony as the holy water scalded her skin like acid. "AAAARRRGGGGGHHHHH!!!" she wailed, her bat wings stiffening in pain. "Make it stop!"
"Why should I?!" Will spat. "Give me one good reason why I shouldn't shove a crucifix straight up your fork-tailed ass, you little bitch! Look what you did to my sister!"
"I swear it was an accident!" Obyzouth choked through gritted teeth as the pain from her burns surged through her burned body. "I... I just had trouble stopping once her delectable life force started flowing into me. It was like booze, only a thousand times more powerful! Besides, I'm gonna be punished anyway by Delilah du Charme, my boss. She runs this club, and she really doesn't want me drawing negative attention to it. Ugh, and you're even a monster hunter! When Ms. du Charme learns I overfed from a monster hunter's sister right in front of the monster hunter... oh Baphomet down below, I'm dead meat!"
"What's this Delilah gonna do to you?" Will asked, a sadistic smile on her face.
"Turn me into a human, I think," Obyzouth said glumly as she fiddled with her bovine horns. "She threatened me with that just last night when I overfed a bit. She doesn't think I'm responsible enough to be a proper succubus."
"She's right," Will nodded severely. "You're gonna fucking kill someone like this, assuming you haven't already. Fine, I'll let Delilah handle your just deserts... and stick around to watch." Her lips once again curled into a spiteful smile.
"Will!" cried Valeria, who was kneeling over Roxy. "Will, you need to come over here fast! It's Roxy. She's..." The vampire stifled a sob. "She's not doing great."
Will sprinted over to Valeria and Roxy's unconscious body. Roxy was barely breathing. Will felt her sister's pulse and listened for a heartbeat. Both were insanely weak. "She's dying, Valeria," Will sobbed, tears pouring down her cheeks, "SHE'S FUCKING DYING!!!"
"I can save her, you know," Roxy said.
"You mean turn Roxy into a monster like you?!" Will spat furiously, here eyes blazing. "Turn her into a vampire?! Steal her away from the Weiss and Harker families and make her a von Karnstein?! Convert her into a foul creature of the night that needs human blood to survive?! No fucking thanks!"
"The other choice is letting her die," Valeria said sternly, glaring at the copper-haired monster hunter. "Are you okay with letting your sister die, Will?"
"What do you care about her?!" Will sneered. "You aren't family!"
"I'm her girlfriend, idiot!" Valeria shouted.
"You could be lying about your feelings!" Will protested. "How do I know you're any more trustworthy than Obyzouth?!"
"I know you just have my word and my family's reputation for good behavior to go on," said Valeria, "but that should be enough right now. Even if I couldn't be trusted, Roxy would still die from Obyzouth's overfeeding. You have no option other than either trusting me or letting Roxy die, Wilhelmina Weiss. Which will it be?"
Will's face softened a bit. "Fine. Even if I refused, you'd probably just mesmerize me into saying yes anyway, so I'll save you the fucking trouble. Just... just do what it takes to bring my sister back." Will broke down weeping, unable to choke out any more coherent words.
Valeria nodded and knelt once again over the nearly lifeless body of Roxy Weiss. The vampire girl reached out and held Roxy's now-cold hand. "Don't worry, Roxy," she whispered through her tears, "Val's here now. I... I'm gonna save you. Please... try to hang on."
