The vial made a small *pop* as the stopper came out. Treyna hesitated once again, "No potion-crafter would openly display a poison, right? Surely..." she looked quickly between the open vial, her wrists bound in chains, and Dara quietly snoozing outside the cell. "Well, here's hoping for invisibility, or something!"
Treyna brought the vial to her lips and with a few drinks the potion was gone. A moment passed as a warmth spread through her body, and then stopped. "A potion of warmth... how convien...wait a moment,"
The rogue's cheeks flushed, her hands trembled, and her body tensed. Suddenly Treyna's breasts surged forward, shredding their way through her leather armor, growing into two gargantuan fleshy orbs rivalling small barrels in size...and weight. The redhead heaved under the new size her breasts, holding them up with her arms. She could just reach the front of them with her arms fully outstretched. "Oh Gods, this is ridiculous, I...hrnng"
Treyna grunted as her body shot upwards a foot or so, and she watched her muscles grow with reckless abandon. Feet and calves ripping out of her knee-length boots, thighs bursting outwards into mighty oaks, her midsection thickened into a hardened tapestry of diamond, the chest below her breasts surging into a wall of muscle, shoulders and lats growing wider and wider, and her arms ballooned larger than an Orc Barbarians.
"By the Gods..." said a voice across the room. It seemed that all of the excessive ripping had awoken Treyna's guard. "What is this madness?!" Dara shouted, drawing her sword.
The red-headed rogue moaned slightly in response, "I don't think it's over yet."
Treyna's body swelled upwards and outwards once again, her head hit the stone ceiling of the dungeon, and she had to bend at the waist to accommodate her new height. Her breasts hung down, and she felt them continue to grow. The muscles throughout Treyna's body exploded outwards, at her normal height she would rival the musculature of rock trolls. Treyna kneeled in her cell, her head grazing the eight-foot ceiling. "Well, it's not invisibility, but the upsides are...quite noteworthy," Treyna thought to herself.
"By...by the order of....I...I command you to surrender!" Dara stammered out, sword pointed toward Treyna's face.
Treyna smiled, reaching for Dara, "Actually, I don't think I will." The massive rogue pinched Dara's sword, shattering the blade. The budding giantess flushed once again, moaning slightly, "You may want to leave now, this next one will be big."
Dara, shaken, ran from the dungeon, calling for anyone who would listen. Treyna tensed, feeling another wave of growth upon her. As her legs lengthened, they broke through the stone floor beneath them. The rogue fell down to the cell below hers, and quickly grew too large for it as well, crashing down another floor. She began to laugh as power and size continued pouring itself into her frame, now sitting nearly three stories tall, covered in steel-hard muscle and silky skin with breasts and hips that erotic dancers would kill for.
As the guards evacuated the tower, the rumble of something within coupled with a booming feminine laugh hurried them away. Dara turned to see a giant, muscled arm push out from one side of the stone monument, the structure flying away as if made of paper. And then Treyna's height rocketed upwards again, legs crashing out from the front of the tower, shoulders and head demolishing the roof. The rogue's bare, muscular body showed no signs of fatigue from tearing through the stone dungeon, and little sign of stopping in it's rampant growth.
"That tower withstood two dozen sieges, and yet seated, that rogue has torn asunder it's wood and stone and steel..." Dara mused quietly to herself, gaping at the still-growing redhead.
"Yes," Treyna moaned to herself, "YES!"
Treyna stood, her growing body pushing it's way out of the tower. When she rose to her feet the tallest point of the tower came only to her hips, five stories in the air. And with another surge her hips removed the tower entirely. Overcome with lust, Treyna pushed her fingers into her womanhood, and her body grew in response. As she worked her hand, Treyna felt the potion's warmth building for one final crescendo, and as she climaxed it released it's power once more.
Treyna's body grew upwards at an incredible pace, and before long had doubled her height again. Not to be outdone, her breasts surged outwards, swelling orbs standing high and proud atop her mountainous chest. Muscle piled onto muscle as pure power coursed through the swelling fibers.
The guardsmen and women below looked up in awe as the rogue ascended even further. The tower's former height coming only to the giantesses knee, Dara realized that the petite thief she had just locked up now stood 20 stories tall.
As her mind cleared, Treyna looked herself over. Huge breasts sat atop a cliffside chest, flanked by shoulders the size of carriages. Her arms bulged outwards as she felt herself over, boulder-sized biceps flexed above forearms larger than a warhorse. Her hands found eight cobblestones on her midsection, flanked by countless diamond-serrated ridges before her wide back showed, itself a tectonic slab of muscle. Reaching down, Treyna's thighs surged outwards in all directions, as large around as the tower she was just imprisoned in, and she found her rear had swelled to thick, juicy proportions.
Treyna smiled, content. "It seems the gallows are not for me today, but what is?"
