"No, I'm sorry, but no. I am not possibly dooming the continent just to satisfy my curiosity. It's too dangerous." Lendriss said, crossing her arms.
Vivian unfurled herself and stood upright.
"Oh come now. Don't be like that. I promise it'll be fun. We can take turns. I'll grow then you. We can make a game of it! Mortals love games right?" Vivan winked, expertly hiding the anger and jealousy coursing through her. She could not let this chance slip away.
"No! I saw how you behaved at 12 ft tall. I can scarcely imagine what you'd be like at 20, 50, or gods forbid 120ft." Lendriss replied.
"Oh like you'd be any better. Stop resisting and have some fun. You know you want to."
"I would be much more refined, and no I don't want to. While interesting, nothing about this phenomenon merits immediate indulgence." Lendriss said, placing her hands on her hips and thrusting her modest chest forward. Vivian smiled at that action, and saw an opportunity.
Vivian floated off the ground till she was eye level with Lendriss's chest. She ran one finger along the elf's delicate new curves.
"Oh, nothing warrants indulgence. Not even these." Vivian said, putting on a sultry tone.
"Um, well. No, not even those." Lendriss stammered.
"Oh really? You looked as flat as me when I first saw you. I know this pain well Lendriss. You mean to sit here and tell me, your soul bound summons, your perfect match, that you are happy with your current curves?" Vivan asked. Lendriss looked away from Vivian but the succubus simply floated back into view. Groping her non-existent tits.
"You're telling me you don't want tits big enough to smother a person's head between? Or their whole body?" Vivian asked, leaning forward.
"Well, um that would be…no. That would be…" Lendriss said weakly
"Big enough to crush a town? A continent? To smother the world! Snuff out entire stars between your massive giant jiggly titties!" Vivan shouted as her own desires overwhelmed her common sense. Lendriss took a step back from Vivian who had begun to laugh maniacally. Shaking her head she took a deep calming breath. Blushing deeply, Lendriss addressed the madly tittering succubus.
"No. Lovely as some of that sounds, the answer is no. For this exact reason! We are not ending life so we can have cup size best measured by celestial objects." Vivan's laughing stopped immediately and turned to pouting.
"...please?" She tried as a last ditch effort.
"No! It's going to be enough of a challenge just to settle our summoning contract with all this nonsense. Especially in a way to keep you under control."
Vivian tilted her head to the side and looked puzzled. She landed on the ground and took a few steps back from Lendriss before speaking
"Control me? Why would that be difficult? Mistress I can't do any of this without you. You basically hold all the power here." As Vivian finished Lendriss turned away to rummage through her pack.
"Where's that quil? Anyway, I wish I held all the power. The binding means you can't harm me without hurting yourself and we share certain effects. But I'm the later half of this strange new spell effect. I get power from you and I can generate power for you, but technically you can feed on anyone to trigger the effect. So we need to…" Lendriss stopped speaking when the sudden sound of her tent flap flying open and falling back shut.
Lendriss slowly turned her head around to confirm what her hearing had already informed her of. She was alone in her tent, front flap slightly askew, and no sign of Vivian.
"Oops…okay, okay I can fix this." She said, closing her eyes, she focused just a tiny bit of mana to her ears. Elves were renowned for their excellent hearing, and adding mana to sharpen her senses should have made tracking Vivian even easier. Which she needed to be quick about lest the little devil be left to her own devices. So it was much to Lendriss' surprise that she didn't hear Vivian, she heard Vivian's thoughts. Huh perks of a soul bond I guess Lendriss thought as she eavesdropped on the runaway succubus.
Of course her initial intent was to track Vivian, listening to her thoughts didn't help at all. Vivian's thoughts were less focused on her surroundings and trying to navigate and more focused on her goal. As those thoughts trickled in, Lendriss somehow managed to pale and blush at the same time. Vivan's thoughts were detailed and numerous, and Lendriss swore she occasionally saw a few images flash into her mind. All of them painted the same terrifying if slightly alluring scenario.
Vivian was going to start growing, and she wasn't going to stop. Ever.
