Even Bigger Little Sister

Not content with it's current proportions, Jasmine's body continued to swell as a result of her 'treatment'. She grew taller, her boobs spilled from her chest and her muscles gained more mass. Merely in this kneeling position, she was nearly 7 feet tall and a hell of an intimidating sight, particularly for her sister who had gotten too used to pushing little Jasmine around - she was mortified that her diminutive sister was now a huge amazon, likely stronger than anybody else in the world at present... and still her massive body continued to expand!

Jasmine was in a state of ecstasy by contrast, finally able to stand up for herself (at least figuratively, what with the ceiling being so low) and able to look down on those who previously considered her to be 'small'. 

Even the super-stretcho-expando-fabric (tm) clothing is struggling to withhold the hulking mass of Jasmine's body trying to burst out.
