Fall! The Futanari Doctor's Corruption! [Parasite Elements Warning!]
[Han Sena. If you hold back your ejaculation for 7 days, I'll destroy my own will and return to being nothing more than a mere cock.]
A day had passed since the parasitic dick's proposed bet.
On the bed in the mansion.
Swish— Sena slowly raised her upper body. Shake... She wasn't wearing any clothes, nor was the blanket covering her, so her E-cup breasts jiggled faintly.
"..."
She then stared quietly at her crotch. Bulge...! Her lower half, covered by a white towel.
Even though she hadn't slept a single hour since returning home, Sena's eyes were incredibly clear right now.
"...It starts today, right?"
As if speaking to a person, she asked her crotch.
Flick! The shaft... something inside shook off the towel once.
The moment the towel flew away, a massive cock that shouldn't belong on a woman came into view.
Throb...Throb...! The fully erect dick sucked up the transparent Cowper's fluid beading at the tip of its glans through the urethral opening—Slurp—
"You have to keep the promise!"
"...!"
Sena clamped her mouth shut and widened her eyes at the parasitic dick's words, as if she couldn't even bear to imagine it.
But then—sneer.
"Just a week... You think I can't hold out?"
She soon flashed a confident smile.
And for good reason. Sena had gone a full year without masturbation or sex since leaving the research facility. Sure, six months ago she'd lost control once because of Ara and jerked off, but she hadn't touched herself since—not even once. That meant she'd suppressed her urges for nearly two years.
'I can definitely do this. No... this is actually an opportunity.'
She'd beening over the cock's endless growth and the absurdly increasing ejaculation volume, but now she'd found the culprit. If she won the bet, she could stop those vile acts entirely.
"No using reagents... or forcing me to cum with anything else... you get that, right? That's not allowed."
"What...?"
Sena's face twisted in confusion at the mention of wet dreams.
"Wait...! Don't tell me those dreams were you too...?"
She quickly realized this parasitic dick was behind those bizarre wet dreams.
"Those disgusting dreams! Better not to have them at all...!"
Sena slowly nodded at the parasitic dick's words.
'Not cumming from wet dreams is a worry, but... a man's balls only store about three days' worth of semen...'
She was a bit concerned about semen building up in her balls, but normally, semen production plateaus after three days—it doesn't accumulate infinitely.
However, there was a fatal flaw in that thinking.
Gurgle...
Sena's benchmark for semen storage was based on a normal man, not a futanarian.
======
Days 2-3.
Clack- clack- Sena walked the hospital corridor toward her office as usual.
"Ah! Good morning, Doctor!"
"Have a nice morning~"
She exchanged light greetings with the nurses she passed, spending a perfectly ordinary morning.
Clack! Clack!
But for some reason, Sena's steps were a bit faster than usual as she passed the nurses.
Whiff... The sweet body scents wafting from between the nurses' legs... from their hidden cunts.
From one nurse, a sweet aroma.
From another, a tangy one.
"Hngh..."
A scent similar to perfume but with a slightly fishy, stimulating edge made her inner cock twitch—Throb...! Throb...! Tension built in her crotch.
'Ever since no more wet dreams... I've been smelling these weird scents...'
She could tell if a female was in heat, ovulating, or even if she'd had sex or masturbated last night—all from the mix of pussy pheromones, fluids, and semen scents.
"Haa... haa..."
Exposed to the thick female scents of the nurses, a faint red glow—the mark of a futanarian in heat—lingered in Sena's blue eyes.
'My head's spinning...'
If she let her guard down even a little, she'd pounce on the bitch with the sluttiest scent and rape her.
Throb...! Throb...!
Not just her dizzy brain—her crotch was rioting too.
Throbbb!! Throb!
Without wet dreams to regularly drain her semen, her tuned cock wasn't at its usual 21cm erection—it was a full 26cm monster.
Gurgle...!!
"Ugh...!?"
On top of that, her balls were swollen like bombs, veins bulging from compressing three days' worth of semen.
Bloooorge...!
With chaos inside, the fabric at her black skirt's crotch outlined the thicker shaft's silhouette more clearly than ever, and—sway— sway— the two massive balls on either side were obscenely visible through the cloth.
'I-It's... fine! Yeah... I can handle this much.'
Clack- clack- Reassuring herself, Sena held her breath and kept walking.
Step- step-
Then she ran into a nurse coming from the opposite corridor.
"Ah! Doctor!"
Han Da Jeong approached with her bright brown wavy hair bouncing, her tone cheerful.
"Good morning, Nurse Han Da Jeong."
At first, as Park Ara's friend.
"The beef yesterday was delicious! Thank you, Doctor!"
"No big deal. I bought it because you all work so hard."
"Hehe."
Later, because of her unusually bright personality, she caught Sena's eye.
Whiff...
'On her period...? A faint blood scent...'
Not the kind of thought to have in front of her smiling face, but the female scent inevitably revealed even sensitive details.
"Well then..."
A bit embarrassed to keep sniffing, Sena moved to walk past.
"U-Um, Doctor!"
But Da Jeong suddenly called her back, turning around.
Clack...
"Hm?"
Sena turned too and looked at her.
"U-Um, that is...!"
Unlike her usual self, Da Jeong blushed and struggled to speak.
"What is it? I need to get ready for consultations..."
Sena glanced at the wall clock and urged the hesitant nurse.
"Ugh... D-Doctor, your... glans is sticking out...!"
Finally, Da Jeong squeezed her eyes shut and blurted it out.
"...Pardon?"
Sena responded with a blank look, glancing downward.
Bloooorge...!
The end of the bulging rod stretching down under her black skirt... Twitch— twitch— A flushed, puffy pink glans peeked out from under the hem.
'The skirt isn't even hiked up... Ah!'
At 21cm erect, pressing it down with the skirt kept the glans hidden. But now at 26cm... or even longer... it could snag on the hem and poke out.
Blush!
"S-Sorry!"
Her face burning under Da Jeong's embarrassed gaze, Sena tugged her skirt down with her hand.
Whoosh- whoosh!
But every time she pressed with the fabric, the glans rebelliously poked its head out.
'You did this on purpose...!'
Sena realized the glans escaping was the parasitic dick's prank and mouthed her accusation, but it played innocent via telepathy only she could hear.
"Doctor..."
"Ahh...! I-I'll tuck it back in right now!"
Finally flustered, she covered the protruding glans with her palm and gave Da Jeong an awkward smile.
'She'll definitely think I'm some pervert now...!'
Sena wanted to cry thinking about her reputation tanking after this.
"I-If it's that hard with the erection... maybe relieving it a little wouldn't be bad? H-Honestly, everyone knows futanarians have strong urges, so self-relief is totally understandable..."
Instead of disgust or contempt, Da Jeong stammered considerate words while glancing at Sena's crotch.
"I-I'm in a bit of a situation myself."
"If there's a reason you can't do it alone..."
Her female scent thickened as she stared at Sena's crotch with a flushed face...
"...I could help you, Doctor."
At those words from her seductive, wet eyes.
Gulp.
"What... do you mean by that, Da Jeong?"
Sena swallowed dryly without realizing and asked back.
"Ah... ahh! W-What did I just say...! Sorry! I wasn't thinking straight. I-I'll get back to work! Doctor!"
Pat-!
Snapping out of it, Da Jeong fanned her face in embarrassment, bowed repeatedly, and fled like she was running away.
"..."
Sena watched her go quietly.
"...Cut it out!"
She yelled at the glans sticking out of her skirt.
Twitch... "Haa..."
Only then did the shaft soften a bit, and the glans barely slipped back inside the skirt.
