Chelsea saw no reason to start off small if she did indeed have such a power, and when her keen eyes fell on one of her students, David Reynolds, she decided he was as good a target as any to test her new powers on. She noticed that David was chatting with two girls who were friends of his. She knew the shortest girl was called Allie, but Chelsea didn't know the other girl, who was much taller, in fact almost as tall as David was. The taller girl was named Charlotte, and she - like Allie - was also English.
As Chelsea sat and watched the trio of students talking, a cheeky little smirk appeared on her face. "How about we get you in touch with your feminine side David?" she said quietly, so nobody heard her. She intended to swap David with the two girls he was talking to.
But what to swap first? Chelsea gave it a moment's thought, then decided to whittle him down in height first. All it took was a quick focus from Chelsea and she gasped when David began to shrink in height, his clothes altering to fit his new dimensions. He shot all the way down to a mere 5'0" tall, while his friend Allie went through a sudden growth spurt... boosting up to David's former 5'10". "Holy cow, it works!" Chelsea giggled, barely able to contain her amusement and surprise. "And even their clothes still fit them." she added, taking note of Allie's skinny jeans and David's stonewash jeans, that still fit them both.
"Let's fill those jeans out shall we." Chelsea then mused, grinning as David's ass expanded into a more feminine shape, his hips also widened as his pelvis became a young woman's. Charlotte's leggings meanwhile deflated considerably in the back as she gained David's backside and his narrow male hips, robbing her of her curvy figure. "Ooh yes, a much better fit now." Chelsea nodded, grinning to herself and getting turned on by what she was doing. She was amazed that her 'victims' remained unaware of what she was doing to them.
Deciding the taller girl now looked too gangly without her shapely hips and bum, Chelsea swapped her again with David, this time exchanging their physiques. Charlotte's body got a little more buff with male muscles, while David's body slimmed down, taking on Charlotte's feminine physique. "Hmm, better, but still some work to be done." she thought, wondering what to swap next.
This time she took from Allie again, and David's short brown hair shifted into his friend's asymmetrical style, while Allie's hair morphed into David's male cut, giving her an even more lesbian vibe. And to compliment his trendy new hairstyle, Cheslea swapped his voice with Allie's too, giving him a girl's voice. But still - Chelsea wasn't finished with these three.
Next, Charlotte's B-cup breasts melted away, forming into David's flat chest and her bra was swapped over too, along with the rest of her clothes. Which meant David was looking increasingly feminine now with several female traits and dressed in Charlotte's blue jacket, pink t-shirt, black leggings and purple plimsolls, as well as her underwear. But he was still a male where it counted, and Chelsea decided to leave him with his penis, at least for now. She got more aroused as she observed the bulge in David's new leggings, and imagined his hard cock stuffed into his new feminine panties. "He looks so cute now." Chelsea chuckled, admiring her handiwork.
Part of her wanted to keep swapping these three around with each other, but part of her wanted to start swapping others too.
