She became 20 but every year she lost, she gained half an inch in height

Mrs. Russo's body shimmered with youthful energy as the de-aging process completed, leaving her looking like a stunning 25-year-old woman once more—5'7" tall, with large breasts, a thick ass, and plush, powerful thighs that turned heads even in her quieter days. She blinked up at you, her eyes wide with gratitude and a hint of mischief.

"Mmm... thank you, boy," she purred, stepping closer and rising slightly on her toes to plant a soft, lingering kiss on your cheek. "I didn't realize how unsatisfying just losing 20 years would feel. Thank you for taking me all the way back to 20. As a reward..."

As she trailed off, a sly smile spread across your lips. "That's not the only change I have in mind."

The magic wasn't done yet. For every year reversed beyond her current youthful form—every one of those 60 years she'd lived past age 20—she would gain half an inch in height, her curves and assets scaling up beautifully in proportion. Her lifespan, too, stretched far beyond normal limits, promising centuries of vitality.

A sudden gasp escaped her lips as the growth began. Mrs. Russo stumbled slightly, dropping to her knees with a soft moan, her hands instinctively sliding between her thick thighs as waves of pleasure coursed through her changing body.

"W-WHAT'S HAPPENING TO ME???" she cried out, her voice a mix of alarm and ecstasy.

You rushed forward without hesitation, wrapping your arms around her in a tight hug. You knew instinctively that the safest—and honestly, the most thrilling—place to be was right there with her, pressed close as she expanded.

She grew steadily, inch by inch, her body lengthening and filling out in perfect harmony. Her breasts swelled heavier against your chest, her thighs thickened around you, and her ass rounded even more dramatically as she rose higher on her knees. The changes were smooth, sensual, unstoppable.

By the time the transformation slowed, Mrs. Russo stood at an awe-inspiring 7 feet 10 inches tall—a true Amazonian beauty towering over everything in the room. The furniture looked comically small around her; doorways would be a tight squeeze from now on. Her large breasts, thick ass, and powerful thighs had grown proportionally larger, giving her an exaggerated hourglass figure that radiated raw confidence and sensuality.

You found yourself still clinging to her, now lifted slightly off the ground, your face nestled comfortably between the warm, plush expanse of her massive cleavage.

She let out a low, satisfied laugh, one enormous hand gently cradling the back of your head as she looked down at you with half-lidded eyes.

"Oh, thank you, my little guy," she murmured, her voice deeper and richer now, vibrating through her chest. "This body... this height... it's perfect. I feel unstoppable."

Her free hand trailed down her own curves, and you could feel the heat radiating from her as she shifted her hips. "Now... how about we celebrate properly? I've got some ideas for how a big girl like me can pleasure her favorite little helper..."

She winked, lowering herself carefully to sit on the edge of the bed—which creaked ominously under her new weight—and pulled you closer, clearly eager to explore just how much fun her 7'10" frame could provide.
