Part One:

Part Two:

Things were rising and descending all at once, meeting each other along the way. Kevin’s testicles burrowed upwards into his torso. The tearing, shifting strands of his jeans rose up to meet his softening, sagging backside, wedging deep between his pillowy buttocks as a pair of denim hotpants. What remained of his shirt similarly formed itself into a white cotton bra, providing desperately-needed support as his chest bulged out and down, swelling and sinking into maternal breasts.

The app trilled happily from the floor as a significant chunk of his lifeforce, extracted as a whirlwind of glimmering golden particles, drained into the speaker of the mobile phone, to be digitized and forwarded to SwapApp. A few gleaming gold strands clung to his skin before being hoovered away. Kevin felt its absence sorely. Twenty years! He felt sluggish, horribly soft, and weak, with a subtle, dull fatigue permeating every cell. To a naturally matured woman, the slow march of the years would have been imperceptible. Flash-grown two decades in an instant, he felt ancient.

He reached for the phone, determined to undo his mistake. The ballast of his breasts swung forward, his broad feminine pelvis swinging out, and he stumbled. His mom snatched up the fallen phone before he could. Cooing in delight, she hugged his arm to her youthful chest. “It worked! You look just like me! Or my curvier sister perhaps," she added, her perky nose furrowing in a frown. "I’m jealous. You make a prettier woman than I was. Come on, we've no time to waste!”

Kevin found himself whisked to her bedroom, where she flung open the doors to her wardrobe, tossing out dresses, heels, panties, and more onto the bed. While the mound of fabric rose, Kevin stood before the mirror, frozen in horror at the situation he found himself in. His fingers traced unfamiliar lines of his face. He was well-maintained for a woman of his years, though the beginning of wrinkles were starting to show. Even the corners of his eyes displayed laughter lines from a life unlived, his soft features exuding a motherly warmth.

“Mr Garvey will just melt when he sees you in this," his mom said giddily, draping a high-waisted pencil skirt over his rump to test the fit.

"Mr Garvey?! Gross! He used to be my teacher. No way I'm letting that old bag of bones ogle me." Kevin whimpered. He remembered the man from his dull-as-dishwater geography lessons from five years ago, the brown tweed suits, the sharp tongue lashings he would dish out whenever Kevin began to slump from boredom. The thought of lustful eyes watching him from beneath Mr Garvey's bushy grey eyebrows made his skin crawl. "I can’t do this!” he whimpered.

“First of all, he's not old. He's only two years older than you are now. And of course you can! Look at yourself. You’re a beautiful woman in the bloom of her life." Her words were falling on deaf ears, and she stepped back, slipping the phone from her pocket. She quietly flicked through the settings of the SwapApp, searching for the right parameter. "It will be fine. You just need a slight change of mind..."

"About him? No way, I hated him! He was always riding my ass back then."

A devious smile crept across his mother's lips. "And you'd hate for him to ride your ass now, would you?"

Kevin hesitated, a warm flush washing over his cheeks and the upswell of his chest as he thought back to that damn teacher... That sonorous, commanding voice... Cold grey eyes penetrating him from beneath brows like storm clouds, while he lashed him with his tongue. Kevin chewed his lip, his pulse quickening. The man had been a ball buster, sure, but... well, he had no balls left to bust. The thought of the man, rod in hand to deliver punishment to his skirted rump intruded on his mind... the man's erection straining against those tight, tweed pants. Oh my...

There was currently a sale on Sexual Preferences on the SwapApp. With a few button presses, his mom had surreptitiously sold his 'female' preference for a handful of credits, trading them for several units of 'male' preference. She smiled to see Kevin tremble, quickly adding another unit to his portfolio of traits.
