Valeria extended her fangs and lowered them to the unconscious Roxy's neck. After finding the dying girl's jugular vein Valeria plunged her fangs in. She began injecting her transformative venom into Roxy's veins to start the vampire metamorphosis that would save her dying girlfriend's fragile life. Valeria then slowly pulled her fangs out of Roxy's skin and stood up to keep vigil over her girlfriend as she began to change.
Roxy, Will, and even Obyzouth stood over Roxy's body, awaiting signs of her change. It was slow going at first. Roxy's dying heart was beating slowly, so it took a while to pump the vampire venom throughout her body.
"I'm so, so sorry, you two!" Obyzouth declared, trying not to move and irritate her holy water burns. "I only meant to take a little life force from her like the other succubi here do. I don't know why I have such a hard time controlling myself."
"'Sorry' doesn't fix it, demon!" Will snapped.
"Actually learning to control yourself will," Valeria added.
Two long, sharp fangs began to slowly poke out of Roxy's mouth. Suddenly, geysers of crimson blood erupted from her mouth and pussy, drenching Valeria, Will, and Obyzouth.
"Whew!" Valeria gasped as she tried to wipe blood off her tits with her hands. "Good thing we're all naked."
Roxy's body now looked even paler than it had before. Her weak breathing and heartbeat finally ceased altogether. For one horrifying moment, Will thought her sister had died. Then Roxy's eyelids slowly fluttered open. "Uhh..." Roxy groaned in confusion as she rubbed her head. "Wha... what happened?"
Valeria pulled Roxy into a tight embrace and kissed her on the mouth. "You almost died, babe! Obyzouth overfed from you like crazy, and I had to turn you into a vampire to keep your soul from passing into the afterlife. I... I almost lost you." She clutched Roxy tighter to her and wept.
"But you didn't, sweetie," Roxy reassured Valeria. A thrilled grin then spread over her pale face. "And now I'm a vampire! So cool! So, does this make me an official daughter of Clan von Karnstein?"
"Not quite yet," Valeria chuckled. "There has to be a ceremony first. Under normal circumstances, what I just did would be a horrible crime that'd get me suspended from the clan for at least a week. The only reason Matriarch Carmilla will allow it is because your life was at risk. I'm still not allowed to perform the ritual itself, though. Only our matriarch can do that. I'll talk to Matriarch Carmilla about what happened, and she'll arrange for your initiation ceremony to happen as soon as possible."
"Wait!" Will interrupted. "You're... joining her clan, Roxy?" Will's voice sounded hurt. "You'd... you'd turn your back on our family... on me?"
Roxy's eyes widened. "Oh." She turned to Valeria. "Would Carmilla let me use the surname 'von Karnstein-Weiss'?"
"Probably," Valeria shrugged. "She's not a tyrannical kind of matriarch at all, and she'll do whatever makes you feel comfortable in our clan."
"Is that a good compromise, Will?" Roxy asked her sister.
"I... suppose," Will answered after a long pause. "It's still gonna be weird for me to get used to being a monster hunter with a vampire for a sister, but I'll do it for you."
"You know, it's a shame you couldn't be conscious for your transformation, Roxy," Obyzouth interjected. "I hear it's super arousing!"
Valeria gazed amorously into Roxy's eyes. "Don't worry, honey. I intend to make up for that tonight."
