Heading to grab her lab coat, Tiffany stopped as she felt strongly as if her insides were churning. She sat holding her belly, at the same time as she felt her panties already at their limits being forced while her private parts seemed to be filled. Realizing that something seemed wrong, Margaret and Abrams laid her on a stretcher.
"Your formula is not yet perfect." Margaret said
"Come here young man. Help me with her, we have to understand what is happening and try to save her before it's too late." Abrams said
Justin ran to help, very worried. He was confident that he had neutralized any fatal side effects of the formula, but the outcome left him very scared. He and the doctor measured Tiffany's vital signs, who was now panting and sweating profusely. Her blood pressure was very high and, fearing a cardiac arrest, they ordered Margaret to urgently prepare a defibrillator.
Upon returning with the equipment, Margaret noticed and pointed out something pushing Tiffany's skirt underneath, and Justin picked up the end of the thing when examining what it was. He felt something he recognized, it was a dick and it was hard, then took his hand out of it.
"I'm sorry, I didn't know you were trans." Justin said to Tiffany, without realizing that both Margaret and Abrams found his speech strange.
"But... I... I'm not, I'm... 100%... a woman." Tiffany said, panting
"But you have a dick and..." Justin tried to say but stopped when Abrams took his place and pulled what was left of Tiffany's skirt. To the surprise of the doctor, his mother and the assistant, there really was a hard dick measuring just over 6 inches between Tiffany's legs, with a sack where her vagina should have been, which was empty.
"Do I have a dick now? This is so wrong and gross but... ohhh, this feels so good, I'm loving this feeling." Tiffany said the best she could, then without warning she took one of her hands to her new dick and started stroking it.
"Stop it Tiffany, get a grip." Margaret scolded the assistant
"I can't, this feeling is so good I can't stop." Tiffany said as she continued to jerk off, with Justin noticing that her dick was still growing and had already gained at least another two inches after being discovered.
Abrams tried to make her stop by force, but the woman was now too strong and he had no chance. Margaret calls for reinforcements to force Tiffany to stop her explicit sexual act, but she did not have full control of her acquired strength and easily knocked down five men who tried to restrain her while trying to push them away. In another attempt, Abrams shot her with a dart loaded with tranquilizers, hoping to put her to sleep, but her dense muscles prevented the needle from penetrating.
Tiffany's cock grew until it reached 11 inches and, at this point, she moaned very loudly as her newly formed testicles, which were the size of oranges, descended and deposited themselves in their place inside her new ballsack.
Margaret made another attempt to stop her, shooting her with a taser, but instead of the paralyzing effect this only stimulated her more, making Tiffany reach her orgasm. The assistant moaned and came, shooting her cum upward, forming an arc and falling to the floor in front of her.
After her orgasm, Tiffany sat on the gurney, panting and looking at everyone, looking a little embarrassed by what she had just done, but her dick was still rock hard.
