Mika sighed thoughtfully and sat himself back on the edge of the bed. The motion made his still-rigid erection swing heavily from side to side before settling, pointing straight upward like an unyielding pillar.
He put on a comically puzzled expression, looking around the room as if searching for clues.
"What could it be...What could possibly be turning me on right now?" He mused aloud, scratching his chin. "There are so many things that can excite a guyâpictures, videos, a pretty girl walking byâbut none of thatâs here."
He gestured vaguely at the empty space.
"At least if there was a poster on the wall or a magazine with a hot cover model, I could blame that. Or if Cecilia was still around...yeah, that would definitely be a possibility. But even sheâs gone home."
"All thatâs left is cold equipment, a sad little fern, and hospital disinfectant. None of that exactly screams âsexy.â So why the hell am I rock-hard like this?"
He looked down at his erection with a bemused frown, giving it a light tap with his fingers.
"Not to mention." He added. "This one feels particularly...enthusiastic. It doesnât feel natural at all."
"Like my body just forced it out. Itâs way more intense than usual, almost like all the heat in me is pooling down there."
Hearing this, Faunaâs concern returned full force.
She stepped closer, eyes flicking worriedly between his face and the throbbing shaft.
"Wait, Mikaâare you saying this..." She gulped, forcing herself to look at it again. "...this erection isnât natural? That it feels off? Like it doesnât belong?"
Mika nodded slowly.
"I donât know how to explain it exactly, but yeah. It doesnât feel quite right. Normally I have full control, but this feels...foreign. Forced. Different."
Faunaâs mind raced.
A nagging doubt crept inâthis could be related to the serums after all.
She needed to confirm.
"With your constitution, Mika..."
She said, trying to sound reassuring.
"...I really donât think thereâs anything wrong. It might just be a big misunderstanding."
"Iâve read research papers about random morning erections in men, perfectly normal physiological response. And since youâve been dozing on and off all evening on this bed maybe itâs something similar."
She forced a professional tone.
"But just to be safe, let me run a few targeted testsâespecially on that area. Weâll see what the readings say."
Mika gave her a doubtful, half-amused look.
"I donât know how to feel about that." He said with a chuckle. "Getting a full diagnostic on my dick makes me feel like I have erectile dysfunction or something."
"I would say the exact opposite..." Fauna muttered under her breath
Mika blinked. "Huh? What did you just say?"
Her face flared crimson.
"N-Nothing! Never mind!" She squeaked, waving her hands. "Just...do as I say. Itâll be a quick test. Donât be a baby about it!"
Mika laughed reluctantly. "Fine, fine. If you want to examine it so badly, Iâll indulge you."
Then he glanced around with a playful grin.
"So...do you have any special equipment? Just for my penis?"
Faunaâs blush deepened. She shook her head quickly.
"No, not at all! Thereâs no apparatus in the world designed solely for...that part. And even if there was..." Her eyes flicked downward involuntarily. "...I donât think anything would fit something your size."
She caught herself again, mortified.
"I-I meanâweâll just use the standard sensors. Theyâll work fine."
But as the words left her mouth, realization struck.
To get accurate localized readings, she would need to attach the adhesive electrode patches, conductive clips, and monitoring leads directly to the shaft and surrounding area.
Normally impossibleâtoo small a surface.
But with Mikaâs extraordinary girth...there was more than enough space.
The real problem was that she would have to touch it.
Hold it.
Position the sensors herself.
Her hands trembled at the thought and she looked up at him hesitantly.
"Mika...could you do me a favor and attach the sensors yourself? I think it would be easier ifâ"
Mika scoffed, cutting her off gently.
"No way, Fauna. I have no idea where theyâre supposed to go, you designed these machines after all. Iâd probably put them in the wrong spots and not to mention that youâre the doctor; Iâm the patient."
"Itâd be ridiculous for me to do your job."
He grabbed the base of his erection casually and gave it a little shake, making it bob invitingly.
"Come on, come onâdonât hesitate so much. Itâs just your sonâs penis. Youâve seen it a million times. Youâve even washed it when I was a baby. No need to be scared. Just do it already."
Fauna swallowed hard.
She had no escape, so with shaking fingers she gathered the relevant electrodesâsmall adhesive ECG patches, thin conductive clips, flexible sensor strips.
She stepped directly in front of him as he sat on the bedâs edge, his erection standing tall and proud between them.
Slowlyâagonizingly slowlyâshe reached out.
But just as her fingertips were about to make contact, the shaft twitched visibly.
"Kyaaâ!"
Fauna yelped and yanked her hand back.
"W-Whatâs happening?! What was that?!" She squeaked, eyes wide. "Is it...is your penis going to bite me?"
Mika stared down at her in complete dismay, then burst out laughing.
"What are you talking about, Fauna? It just twitched a little! Itâs not a dog thatâs going to bite you!"
But inside, Faunaâs mind raced.
The flared head did look almost monstrousâthick, glistening, powerful.
Like it could devour her if it wanted.
But she couldnât let him see how flustered she was.
Gathering every ounce of courage, she steeled herself.
âItâs just medical. Just sensors. For his health.â
She reached out again.
This time, her fingers made contact.
She wrapped her hand around the middle of the shaft to hold it steady.
The sensations hit her all at once.
Firstâscalding heat.
It was like grasping a metal rod fresh from a forge, radiating warmth that seeped straight into her palm.
Secondâunbelievable thickness.
Her fingers couldnât even close fully around it.
She would need both hands to encircle the girth completely.
Thirdâunyielding hardness.
She had expected something softer, more pliableâflesh and skin.
Instead, it felt like an iron bar wrapped in the thinnest layer of velvet-smooth skin.
Solid.
Immovable.
Alive with pulsing veins beneath the surface.
Faunaâs breath hitched.
She couldnât believe her son carried something like this between his legs every day.
âHow had Cecilia even taken it inside her?â
It would be painfulâimpossibly so.
And yet...
Her body betrayed her again.
A deep, insistent throb between her thighs.
Fresh slickness soaking through her panties.
Her pussy clenched involuntarily, aching, as if begging her to guide that monstrous length closerâto let it fill the emptiness she suddenly felt so acutely.
But nonetheless, Fauna pushed those treacherous thoughts awayâor tried toâand forced herself back into professional mode.
She was a doctor.
A scientist.
A mother concerned for her sonâs health.
Nothing more.
Mika, meanwhile, was overjoyed inside.
Feeling her small, trembling hand finally wrap around his shaft with such determined grip sent a thrill straight through him.
He kept his expression neutral, but every nerve sang with quiet victory.
Fauna then carefully took the first adhesive patch between her fingers and pressed it firmly against the thick base of his penis.
To secure it properly, she had to push down slightlyâforcing her hand to tighten around the scorching, iron-hard length.
It twitched again in response to her pressure, throbbing powerfully against her palm.
She gulped.
She genuinely believed, in that moment, that it was aliveâsome independent creature that might lash out or attack at any second.
Still, she pressed on.
One by one, she placed the probes and sensors along the shaftâmoving from the base upward, then downward, touching every inch.
Her fingers traced the underside, the top ridge, the sensitive head.
When she reached the tip, she had to pinch the bulbous, flared head gently between thumb and forefinger to hold it steady.
It was even thicker than the shaftâswollen and intimidating.
For a wild second, she wondered if her son had some kind of abnormal growth or tumor.
âHow could a human head be this disproportionately large and menacing?â
But she forced the thought away and attached the a sensor there.
And throughout the process, a recurring problem kept frustrating her.
The veins.
They were raised, rope-thick, crisscrossing the surface like cables.
Every time she tried to press a patch flat, a prominent vein would bulge in the way, popping the adhesive loose.
Fauna frowned in frustration, looking up at him with pitiful, pleading eyes.
"Mika...do something about these veins." She said softly, almost whining. "When I try to stick the patches on, they just come off again. Your veins are blocking everything. I donât know what to do..."
Mika glanced down with a casual shrug.
"Just push them aside. Theyâre not fixed in place. Use the tip of your fingerânudge gentlyâand theyâll move."
Fauna gulped. But nonetheless slowly, hesitantly, she pressed the pad of her thumb against one prominent vein and eased it sideways.
To her surprise, it shifted obediently, sliding over just enough for the patch to adhere.
Curiosity got the better of her.
Her thumb lingered, tracing the vein upwardâfeeling the steady, powerful throb of blood surging through it, feeding the monstrous erection.
It was hard, almost rigid itself.
âEven his veins are so thick...â
She moved to another vein, then anotherâslowly rubbing, exploring, fascinated despite herself.
Only when she realized how long sheâd been caressing them did she snap out of it and hurriedly finish the remaining sensors.
Finally, only one sensor remained.
The last placement point was directly beneathâon the heavy, swollen sac.
Her sonâs balls.
