Still recovering from his first orgasm as a male, Jenna stared at his softening penis. "I... I'm a boy..." he said with a soft delicate whimper. Thoughts began racing through his head: "It worked at first... What went wrong? Am I stuck like this forever?" He tried to get up, when he caught a glimpse of himself in the mirror.
His mirror image wasn't very masculine; in fact, he almost looked like his old self. No broad shoulders, very little muscle definition, and... surprisingly wide hips. Turning around, he was greeted by a lovely back and a nice round butt. With his left hand he grabbed one buttock and noticed that it was still rather soft. And his legs were still long and shapely. Next he examined his face. It had soft round features, high cheekbones, arched eyebrows, and all the other features necessary to look mostly feminine and only slightly boyish. This gave him an idea.
Within moments he had found a skirt and simple blouse to wear. As he was buttoning up the blouse he got another idea. He grabbed a pair of black knee socks and some nice shoes with sexy heels. After putting them on he applied some make-up to complete the look.
Back in front of the mirror Jenna ran his hands down his sides, and struck a pose. "Not bad." he said in his still feminine voice. What he saw was pretty much indistinguishable from an attractive girl lacking in the chest department. It was the perfect "disguise". While he would search for a way to turn back, nobody would ever find out that this "girl" was really a boy.
