Chapter Title: Bathroom
-----------------------------------------------------------------
A week had passed since I first bought the onahole.
For the first two days, I just thought, 'Damn, what a great onahole. Feels amazing.'
But on the third day, during online class, I secretly jerked off and happened to catch Shin Ayoung's reaction. That's when everything changed.
I was now 99% sure this onahole was linked to Shin Ayoung's pussy.
Right now, two onaholes sat in front of me.
One was the large onahole I'd bought after seeing the ad, and the other was the small one that came free as a gift.
I felt like I owed the seller 108 bows of gratitude.
So, what functions did these two onaholes have?
I was certain the small one was connected. But what about the large one?
And was it just simple connectivity? No way a dreamlike item like this only had that feature.
I spent the next four days observing.
Staring at that tightly shut pink pussy made me hard again, but I held back, remembering my goal.
In the end, I discovered three interesting things.
First: The pussy and anus would twitch open several times a day.
Luckily, no fluids leaked out—just the holes gaping and closing.
Second: Both the large and small onaholes were synchronized.
They moved together whenever the holes twitched.
Third: It only reacted to things that touched my body or had touched it.
A bug landing on it didn't trigger anything, but poking with a pen did.
This was just from observation, so hands-on testing would reveal more.
Still, I was satisfied with this intel.
Two days ago, after figuring this out, I ordered some fun toys.
Tomorrow's lab session was going to be exciting.
Has heading to the lab ever felt this fun?
My bag looked a bit heavier than usual, but my steps were light.
'Small onahole, lube, vibrator... and some clothes to muffle any noise if needed. Perfect.'
I'd bought a wireless rotor controllable by remote from my pocket.
Four days staring at Shin Ayoung's famously pretty pussy without touching it had driven me insane with lust.
Today was liberation day.
'Does her pussy match her face? That pink color was fucking gorgeous...'
Lost in happy fantasies, I arrived at the school building.
Waiting for the elevator, a fresh lemon scent wafted over.
Glancing sideways, Shin Ayoung approached in a beige long coat.
'Wow, her fashion's on point, but that face makes her perfect.'
-Ding. First floor.
I'd been sneaking whiffs of her scent when the chime rang.
Cursing the fast elevator, I headed up to the lab.
An hour later, my all-nighter studying paid off—I finished the day's work early.
Now, time to "experiment" and watch Shin Ayoung's reactions. I opened my bag.
First, I slathered lube inside the onahole and shoved the rotor deep.
The lube wasn't strictly necessary, but it felt like prepping for the main event.
Twitch!
Shin Ayoung's legs trembled briefly, but she dove back into her experiment.
Time to crank the rotor to [low].
"Ngh!"
Shin Ayoung, building a circuit while standing, let out a weird noise and staggered.
Her classmates stared oddly, so she quickly made excuses.
"Ah... I stubbed my foot on the desk corner... Don't mind me."
She laughed it off, waving her hand. But we hadn't even really started—would she be okay?
[Low] seemed bearable, so I bumped it to [medium].
Click! Whiiirrrr.
The vibration intensified from my bag. I moved to a spot where I could see her profile.
Shin Ayoung bit her lip, enduring it. Her hips twitched, legs quivering faintly.
She held out surprisingly well... for ten minutes.
"TA! I need to use the bathroom."
She fled to the restroom.
I tucked the onahole into my inner pocket and followed.
Passing her seat, I eyed the round chair. It glistened under the fluorescent lights, a bit of liquid on it.
'She came a little? Looks like pussy juice from the clearness.'
In the quiet bathroom stall, I pulled out the onahole.
As expected, the inside was soaked, juices leaking out.
I switched it off and waited. Soon, the women's restroom door opened.
Unsteady footsteps.
I cranked it to [high] and ground the rotor hard against her G-spot.
Experience had taught me that was her weak point.
Whiiirrrr!!
"Nngh! Ahhh!"
A moan echoed down the hall with the stronger vibe.
Then the bathroom door reopened and locked with a click.
'U-turned right back in.'
Keeping the G-spot assaulted, I licked her clit once. The insides clenched, squirting juices.
The forceful spray soaked my shirt and face.
Her pussy walls gripped my fingers and rotor tight, orgasming nonstop.
I eased off, pulling out hand and rotor together. Clear fluid gushed onto the floor.
The pink pussy spasmed, strands of juice dangling.
The erotic sight had me dropping trou and slamming my cock in.
Squish!
Four days of edging made me nearly cum on insertion, but I held back.
Left hand rocked the onahole; right hand teased her clit with the rotor.
"Nngghh!! Mmph... hngh!"
Faint moans synced with my thrusts.
Just shaking it solo before was nothing—her real moans were driving me wild.
How many strokes in?
Her insides writhed, clamping so tight it hurt.
I sped up, feeling cum rise, and pressed against her cervix, unloading.
Spurt... splurt...
My cock pulsed endlessly, pumping semen.
I spread the hole slightly—white cum sloshed inside.
After cleanup, back in the lab: Shin Ayoung still hadn't returned.
Soon, she slumped back to her seat, utterly drained.
Quick check of the onahole: Less than before, but cum still deep inside.
'Makes sense—she can't scoop it out without getting caught and becoming campus gossip.'
The thrill of my cum inside the pussy right in front of me was electric.
Wanted to torment her more, but she looked done for the day.
The transparent cock that terrified me daily with its sudden appearances... was gone.
Finally free?
Relief at regaining control of my body mixed with regret—I craved that insane pleasure again.
Truth be told, last night I'd masturbated out of loneliness after so long, but it paled in comparison.
'No, Shin Ayoung, you're crazy! How can you think that? I'm the crazy one.'
Slap slap!
I smacked my cheeks to snap out of it.
Mid-experiment in the lab, something small and round slipped into my pussy.
"Ngh!"
'What... the hell? A vibrator? No way...'
The lewd noise drew stares from classmates.
I made excuses, pretending to be calm.
'Of all times... At least before it happened when I was alone. Now I have to endure...'
Whiiirrr.
Thankfully, no sound leaked—just the vibration.
But my crotch soaked fast, so I fled to the bathroom to wipe up.
Bang! Click.
I yanked down my pants. My white panties were stained wet; pants damp too.
Lucky they were black—no visible wet spot.
Holding the panties, drops fell like from rain-soaked cloth.
Couldn't wear them anymore.
I layered toilet paper over my pussy as a makeshift pad.
Hid the soaked panties and waited for the vibe to stop.
It did soon enough.
Heading back, a massive vibration hit—my back arched involuntarily.
"Nngh! Ahhh."
Covering my mouth, I retreated to the same stall.
'The upper part... my sensitive spot. Just that and I'll... cum quick...'
Feeling the vibe, clit stimulation joined in.
"Nngghh!! Mmph... hngh!"
I bit my clothes hard to muffle, but the pleasure made my jaw tremble; moans escaped.
'Clit and G-spot at once is cheating... I'm cumming... cumming cumming!!'
Squirt... shhh...
Shoulders against the tank, my back bowed gracefully.
The gush soaked the stall door.
"Haa... haa..."
The rotor slipped out. Is it over?
Squelch...
The massive transparent cock from days ago pressed at my entrance.
It plunged in, ravaging mercilessly.
'Ahii... ♡ I just came... don't thrust like that... I can't...'
I lost my mind; lewd cries echoed in the bathroom.
"Ahhh... so hot... ♡ Aa... hngh..."
I surrendered to the endless waves of pleasure.
Legs splayed wide, face slack.
Anyone seeing me head-on wouldn't believe it was Shin Ayoung.
Snapping back, I rushed to the sink to extract the cum.
Fingers couldn't reach—the load sloshed too deep.
I wiped the entrance roughly; the rest would wait for home.
'Again... I lost... I shouldn't...'
But oddly, my body felt refreshed.
Relieved lust? Or exhaustion?
'Gotta finish the experiment quick and go home... hate feeling it slosh in my belly...'
