Chapter 13: Side-Effects

Leah's second trip to the body mod clinic was even more awkward than her first. When she originally had the procedure, she started female and finished as a futa. But now, she was returning as a super horny futa with an erection lasting more than one hour.

Inside the doctor's office, Leah once more was adorned in a teal robe, sitting across from Amy and Pamela. Beneath the robe, a condom lay fixed on her hard-on, which had been leaking precum all morning.

The wait was killer. Hopefully, the doctor could explain what was happening to Leah's downstairs area.

"Hello, girls." the doctor greeted them, making his entrance. "Now, Leah...." he began. "I'm afraid I have some bad news."

This definitely wasn't helping Leah's nerves.

"We were only recently made aware of this, but it seems the mutagen we used in your procedure contained a new protein substitute that our manufacturers neglected to inform us about."

"Oh God!" Leah cried, cupping her face in her hands.

"As a result, some patients have had an allergic reaction to the substitute, leading to.... side effects." the doctor continued.

"Wait. What kind of side effects?" Amy asked.

The doctor sighed. "When Leah first underwent her transformation here, she was 5.25 inches when erect. Now, after measuring her in her current state, it would seem her penis is 7 inches when erect."

The three young women were shocked.

"Are you saying I grew 2 inches in a week?" Leah questioned.

"Actually, you only grew an inch and three quarters in five days, but I understand the worry. Your testicles also seem rather swollen, each one being about the size of an egg now." the doctor elaborated. "Furthermore, you seem to be suffering from an acute over-production of precum. Tell me, when was the last time you masturbated with your phallus?"

Leah answered, embarrassed. "Uh.... almost a week ago, when I was here before."

"Mhm. And you also said a chastity device was mistakenly overused?" the doctor probed further.

"Umm.... y-yeah." the futa whimpered.

"I see. Well, I think I have a few ideas that might fix your problem. The most drastic solution would be to schedule the immediate reversion of you to your original, female self."

"Woah. Do you really need to go that far for one screw up? I thought you guys were good at fixing mistakes." Pamela piped up.

The doctor rubbed his brow before answering.

"Yes, we can undo and tweak most alterations we make to the human body. However an unforeseen complication of this caliber must be handled very delicately. If we were imprecise in editing her body as is, it could cause a cascading sequence of new problems. It'd be much easier to wipe the board clean and start over."

"I can't start over! The month's already a quarter done!" Leah protested.

"There is another possibility, but I doubt you would like it any better." the doctor offered.

"What is it then?" the girls asked in unison.

"Leah's **** attempts at sexual inactivity have seemingly exacerbated the effects of the allergen. Her body is attempting to reject the chemicals she's ingested, flushing it out through her sweat, tears, and.... ejaculate."

"So THAT'S why she's leaking so much!" Pamela realized.

"Precisely." the doctor explained. "So, if she were to give in to her bodily urges and regularly achieve release, it might alleviate some of the more aggressive symptoms."

"Are you kidding me?! The whole point I did this was to prove I DON'T need to masturbate all the time!" Leah angrily shouted.

"Hey, I said you wouldn't like it." the doctor reminded her.

"Then I guess we're done here. Thank you, doctor, but I'm afraid I have a challenge to get back to." Leah said, rising to her feet.

The doctor, as well as her two friends, rushed to stop her.

"Woah, woah, woah. Leah," her besties said. "Think about this. You could seriously mess up your body doing this. If we have to choose between the bet or our friend, we'd rather have you, safe and sound."

"I have to agree with your associates, Leah. I understand you care deeply about this contest, but I simply cannot recommend such reckless behavior! Your symptoms could easily worsen, not to mention the possibility other side-effects we do not yet know about!" argued the doctor.

"Doc. Pam. Amy. I get it. You're worried about me and I appreciate it. But I made a promise, a promise not easily broken. I will not cum until December first! And there is nobody who's gonna stop me from making that happen, okay?!" Leah firmly stated.

The girl was resolute in her choice. Consequences be damned, she was determined to live up to her word. Who knew what other struggles were in store for the stubborn, swelling futa?
