...'Transgender'. He had wondered occasionally what it'd be like if he were a girl, so decided it'd be a good place to start. Another laser line, this time blue, flicked across Jason's body, steadily shifting through purple and then pink.
Once it finished crossing his body, all of a sudden he had a weird vision. A man and a woman, naked and having sex. The man's penis thrust in and out of the woman's vagina more and more forcibly and rapidly, and they orgasmed. He saw the cock shoot thick white cum inside the pussy, and his vision zoomed in until he could see the sperm inside the liquid racing through the woman. Soon they surrounded an egg which was way larger than the mass of seed, and set about wearing away at it.
"What you are seeing," text from the machine explained, "is your conception. One of these sperm, which has a Y chromosome, will soon get inside the ovum, fertilize it, and you will start to form into a male." Sure enough, Jason soon saw one of them enter the egg. The footage then began to run in reverse and the sperm got extracted from the egg. "However, your conception has now been altered to allow a sperm with an X chromosome to replace it." The footage ran forwards again, and a different sperm got inside the egg instead. "Now you will start to form into a female."
For a second he felt skeptical about this- that wasn't possible! But then Jas... Jas... he realized he couldn't remember his name as a boy. As his vision returned to normal, he saw when looking down that he was now just as naked as the digital version of himself. He felt strange, slowly realizing that feminine hormones were surging through him, preparing to turn his male body female.
Before his eyes, Jas... saw his body get reshaped by his altered genetics. His muscles became lither and leaner, his arms and legs and hands and feet more petite. His figure turned curvier, hips widening and torso slinking inwards, and his hair lengthened while still staying light brown and straight. He saw the reflection of his face alter, with softer cheeks, puffier lips and a smoother jawline without the bulge of his larynx, his voice's pitch increasing too. "I'm... I'm pretty," he whispered.
By now Jas... looked feminine everywhere but his chest and crotch. Once the feminizing hormones seized his reproductive system, the strange sensations became intense and overpowering. He gasped in his softer voice as he saw his nipples expand and develop into mammary teats, and his chest swelled with warm soft flesh as breasts formed that soon grew to C cups. "I have tits?!" he exclaimed.
Then came the most intense sensations of all as his penis was reshaped, and a sense of emasculation and of feminization intermingled. His phallus shrank into him, and his testicles moved up inside the body, forming ovaries that linked to a newformed womb.
Jas...'s entire sense of identity was metamorphosing as he realized he wasn't a man, she was a woman. His penis receded into a tiny sensitive nub and became her clitoris, and his scrotum tucked inwards, linked to a passage forming inside her and unsealed to form her vagina.
Her name came to her as her changes completed- she was called Jasmine. She remembered being Jason, but realized no one else would remember she had been a boy. To her relief, her body was now covered by a cute floral print sundress.
Staring at the booth's options, she wondered about using it for something else now, or if she should get out and see what her life was like as Jasmine...
