Three weeks had passed since that strange bite, and life for Rio Morales had changed forever. The once ordinary woman had awoken to a body transformed — taller, stronger, fuller in every sense. Her curves had grown impossibly exaggerated: her gigantic breasts bouncing and jiggling with even the smallest movement, soft sloshing sounds muffled under the tight stretch of her costume, while her massive rear swayed with heavy, unmissable wobbles whenever she shifted her hips. Despite the overwhelming size of her new form, she carried herself with a surprising lightness, a spark of upbeat confidence she never used to have — one of many strange side effects of the spider’s bite.

Now, clad in her freshly made black-and-red spider suit, Rio stood proudly, admiring her reflection. The emblem stretched across her chest struggled to stay centered as her enormous bust shifted and bounced with every breath. Her thighs pressed together thickly, her hips wide and commanding, the suit straining to contain her swaying rear. At her wrists, the custom web-shooters gleamed faintly — devices you had helped her build, the final piece of her heroic ensemble.

She turned to you, her masked face grinning, voice buzzing with energy she could barely contain.

Rio Morales: “Can you believe it? Just three weeks ago I was… normal. Now I’m climbing walls, lifting cars — and look at me, I’ve never felt so alive. All thanks to you and these…uhhh what did you call them…OH! The web-shooters.

Rio stood tall in her new suit, her towering, wide figure shifting with restless energy. Her massive curves jiggled with every small motion — her chest swaying with soft sloshes, her wide hips and slightly chubby belly rippling as if her whole body couldn’t contain the thrill inside her. She adjusted her gloves, her eyes bright behind the mask, practically glowing.

Rio Morales: “This is just too exciting, I can’t wait to swing out there!” she squealed, her voice breaking into a high, girlish pitch of pure joy.

Before she could stop herself, she stomped one foot down in a burst of excitement. The entire room shook, her gigantic chest bouncing wildly while her rear wobbled in heavy ripples. For a moment, she just stood there wide-eyed, realizing her own strength.

She pressed a hand to her chest, taking a deep breath, grounding herself the way she always did when life demanded calm.

Rio Morales: “Ay Dios mío… be calm, Rio. Be calm,” she muttered
