All of it...

Mary Jane's hand hovered over Peter's mug, the vial tilted precariously. A single drop clung to the rim, threatening to fall. Time seemed to slow as she watched it, her mind racing.

What if a few drops weren't enough? What if Peter's enhanced physiology fought off the effects? The thought of facing Craig's disappointment and anger made her stomach churn.

Before she could second-guess herself, Mary Jane upended the vial, emptying its entire contents into Peter's tea. The pink liquid swirled and eddied, creating mesmerizing patterns before disappearing completely.

With trembling hands, she carried the mugs into the main room. Peter accepted his absently, still focused on his work. Mary Jane perched on the edge of the bed, watching intently as he took his first sip.

At first, nothing seemed to happen. But as Peter drained the mug, Mary Jane noticed subtle changes beginning. His shoulders seemed to narrow slightly, his jawline softening. When he stood to stretch, she realized with a start that he appeared shorter - or was that just her imagination?

"I'm not feeling so great," Peter mumbled, rubbing his temples. "Think I'm gonna lie down for a bit."

Mary Jane's heart raced as she watched him curl up on the bed. His body seemed to shrink before her eyes, growing softer and more feminine with each passing minute.

Peter's chest began to swell, small puffy nipples pushing against his t-shirt. His hips widened, thighs growing fuller. Even his facial features were changing.

Mary Jane watched in mounting horror as Peter's transformation continued. His hair seemed to lengthen before her eyes, growing past his ears and softening into loose waves. His lips plumped, taking on a rosy hue as if he'd applied lipstick. Even his eyelashes appeared longer and thicker.

Peter shifted restlessly on the bed, a small whimper escaping his increasingly feminine mouth. "MJ? I feel... strange," he mumbled, his voice higher and softer than before.

Mary Jane's heart pounded as she took in the changes overtaking her husband's body. Peter's shirt had ridden up, exposing a strip of smooth, hairless skin where his treasure trail used to be. His stomach dipped inward, creating a delicate hourglass shape as his hips continued to widen.

"Oh god, what have I done?" Mary Jane whispered, horrified yet unable to look away.

Peter's legs, once lean and muscular, were now shapely and feminine. His feet seemed smaller, toes more delicate. Even his hands had changed, fingers tapering gracefully.

As Mary Jane watched, transfixed, Peter's chest continued to swell. What had started as small, puffy nipples were now unmistakably breasts, straining against the fabric of his t-shirt. They looked to be at least a B-cup and still growing.

Peter's eyes fluttered open, glassy and confused. "MJ? Why do I feel so... different?" He raised a hand to his throat, startled by the sound of his own voice. It was unmistakably female now, light and melodic.

Mary Jane could only stare as Peter struggled to sit up, his movements clumsy as he adjusted to his new center of gravity. The sheet fell away, revealing the full extent of his transformation.

Where once there had been a lean, muscular male body, now sat a curvy, undeniably female form. Peter's breasts were now easily a D-cup, heavy and round. His waist nipped in dramatically before flaring out to wide, childbearing hips. Even his face had changed completely - delicate features, full lips, and large doe-like eyes framed by those impossibly long lashes.

"What's happening to me?" Peter gasped, his new voice rising in panic as he finally began to realize the extent of the changes. His hands flew to his chest, cupping his newly-formed breasts in disbelief. "MJ, what's going on?"

Mary Jane opened her mouth to respond, but no words came out. She could only watch in stunned silence as her husband explored his transformed body with trembling hands.

Peter's fingers trailed down his flat stomach, pausing at the waistband of his boxers. With a look of trepidation, he slipped a hand inside. His eyes widened in shock.
