You start to feel an intense heat tingle through your body and the person who injected you notices how hot you're getting so they ripped of your clothes and you're naked. You couldn't tell if the person was being nice or if they wanted to torture you more by making you watch yourself transform naked, because you can't even see the fucker's face. You feel the muscle and bones readjust in your face cracking and bending to become something else, something more dainty, then you feel like your vocal cords are changing and you feel pain in your chest causing your new voice to come out. It was very high pitched and mounds were forming on your chest. You moaned with your pitching increasing every second and your breasts were perky and nice, you couldn't quite make out the size but they looked to be a C or D cup. You felt your spine expand as you gained height, you're 5'10" now you have to be maybe 6'2" or 6'3".
"This cannot be happening, I am dreaming!" You scream in your head trying not to accept the situation that befalls you. You notice your stomach is getting flatter and more toned before an 8 pack of abs forms and you hear bones crack as your hips expand and waist narrows. Your blonde hair grows reaching past your new breasts before turning a nice shade of chocolate brown. Then the real pain comes as your penis and testicles retract into your body before turning into a new vagina and your internal organs shift as well to account for your new reproductive system. You breathe heavily as your transformation finishes still in shock of what just happened to you and you pass out as sweaty and confused mess.
