37th Rule, Finishing in the Bathroom with Super Aroused Marin (1)
"Ah, Miss? Where are you rushing off to all of a sudden?!"
"Shut up and just follow me."
We barreled down the hallway under the stares of all the students and arrived at none other than the women's restroom tucked away in a quiet corner.
Marin grabbed my wrist without a hint of hesitation and tried to drag me into forbidden territory for guys like me. I frantically tried to stop her.
"M-Miss! If we're going, at least use the men's room!"
Something felt ominous. A guy stepping into the women's restroom could lead to irreversible disaster. So, even if it was a bit presumptuous, I suggested the safer option.
Marin shot me a sharp glare, confirmed no one was around, and kicked open the door to the men's restroom.
Bang!
The moment we locked the door to the stall at the far end—the one with the big window on the wall—Marin grabbed the zipper on my pants and yanked it violently.
"Hurry up and pull it out."
"......Pardon?"
"Your dick—pull it out now!"
Her scream carried a desperate edge, like she was on the verge of tears.
Marin gripped the rock-hard shaft straining inside my pants.
Looking down, her face was more frantic than I'd ever seen. She panted hot breaths like she was losing her mind.
I took her hand off the zipper and slowly pulled it down.
Whoosh!
Out sprang the cock that had been throbbing all lecture long, nestling right into Marin's embrace.
"Haa...... It's out...... ♡."
Marin planted a deep kiss on the precum-smeared tip of the glans, then lost all reason and started licking it with her tongue.
Slurp♡.
A string of her saliva mixed with precum stretched from her tongue.
She pressed my cock against her cheek, feeling its pulse for a moment.
"I can't hold back anymore...... ♡."
She shoved my chest with both hands.
Thud!
Her force made me sit on the toilet seat. She immediately stepped up onto my thighs—shoes and all.
Step! Step!
The chill from her shoes on my upper thighs, plus the gritty sand grains stinging a bit, sent shivers down my spine.
One hand gripped my shoulder, the other seized my rigid cock.
She aimed it at her dripping slit—strings of arousal dangling—and swallowed it whole without a second thought.
Squelch♡.
"Guh!"
So slippery.
Her pussy had been tormented all class, so it slid in effortlessly into that tight channel.
As my cock pushed deeper, her walls clenched and writhed around it.
The moment it hilted to the root, the tip pressed firmly against her cervix.
"Haa...... ♡."
Like a bitch in heat surrendering to instinct, Marin made an ecstatic face and pulled me into a fierce hug.
Her slender arms and legs wrapped around my back. Pressed against her chest, I could hear her heart pounding wildly.

"Hngh...... ♡."
Just from insertion alone, Marin hit a shallow climax, squirting hot fluids.
Drip, drop.
The sound of her tide splashing into the toilet water below.
Every convulsion made her limbs squeeze me tighter.
"Hnnngh...... ♡."
I felt it every time, but her unconscious squeezes on her walls were getting tighter by the day.
I had to tense my cock or risk it snapping under the pressure.
As I panted, enduring her contractions, Marin whispered in a weak voice.
"Puppy, you can cum inside today. No—you have to. I got birth control from Evelyn just in case."
With that, she engulfed my ear in her hot mouth.
Raw insertion without a condom let me feel every ridge of her pussy vividly.
Her tight embrace overflowed with affection, so the moment I relaxed my grip...
Spurt! Splurt!
Like it had been waiting, my cock unleashed hot semen straight into her womb.
The sensation hit—my entire shaft coated in scorching cum.
Her once-sticky walls turned slick with semen, making her ridges squirm even more violently.
They hugged and stroked my cock lovingly, just like Marin hugged me.
"Haa...... ♡. It's finally here...... Puppy's thick seed inside me...... ♡. So hot...... My womb's melting...... But it feels so happy...... ♡."
Marin lifted her head from my shoulder.

Her heart-shaped pupils scanned my face, then dropped to the heavy sensation below. She flashed a sultry smile.
"You must've emptied everything...... So why's it even bigger than before? Planning to rip me apart from the inside?"
Maybe because of her loving gaze.
Despite dumping a full load into her womb, my cock showed no signs of softening, just as she said.
Seeds scattered in her baby-maker, yet instead of scolding me, she pecked my cheek.
That lewd sight made blood surge back into my cock.
"......Does this mean we can go again?"
"Yeah, but just a short break—!"
"Shut it~♡."
Smooch♡!
Marin planted her feet on the toilet seat and lifted her hips.
Thanks to the mix of fluids, her sticky walls released my cock with a wet pop.
But instead of pleasure, a sharp, unpleasant tingle hit my nerves.
"M-Miss...... I just came, so the tip's still super sensitive......"
I squeezed my eyes shut and protested weakly, but Marin hooked the glans on her entrance, shivering with a wicked grin.
"I'm not some part-timer, you know? I'm your owner. I don't care how you feel—I'm not satisfied yet~♡. I'll milk those balls dry~♡. You want that too, right, puppy?"
Slam♡!
No time to answer—her ass crashed down, slamming my thighs.
"Hngh♡!"
The violent pleasure surging through my cock made me moan involuntarily. Drool pooled at my chin and trickled between her breasts.
Even after flooding her womb with hot life, my cock's heat wouldn't cool.
Her gripping walls tormented my post-orgasm sensitivity, making it swell harder and fiercer.
I buried my face in her chest, gasping for breath.
"Haa...... ♡. Haa...... ♡. This is it...... Watching puppy suffer while this massive cock churns me up nonstop. This is exactly what I wanted!"
Her grip on my shoulders tightened. Between her pale thighs, our mixed fluids—my semen and her juices—dripped steadily.
"Your cock's reshaping my insides! No more settling for dildos♡!"
The obscene plip, plop echoed in the quiet stall over the toilet water.
"I want to conquer you♡! That superior male who beat me—I'll tame him with my trained pussy walls—!"
Squeeze!
Her words stimulated me. Despite the mind-melting pleasure, I grabbed her soft ass with both hands.
"Haahk—♡!"
Her back arched like a bow, head thrown back. She squirted scorching tide between our crotches.
Splaaash!
It all mixed into the toilet water.
Glug! Glugluglug!
Marin halted, fully sheathing my cock again.
Her pupils rolled back, dilated. Her open mouth panted hot breaths, tongue lolling out.
That erotic sight drove me wild.
I grabbed the back of her head and pulled her close again.
"Hmph♡!"
Squeeeze! Sqsh!
She squirted again, her walls clamping with insane pressure.
Just as I was about to pump another ruthless load into her womb—
Creak!
The restroom door burst open outside. I frantically clamped Marin's moaning mouth.
Step, step. Step, step.
A group of male students approached.
We froze, holding our breath, but—
Splurt! Spurt!
My peaking cock relentlessly flooded her cervix.
As our mixed tide and semen dripped toward the water—
"Hey, you see that girl earlier?"
The guys' conversation drifted in.
"Who?"
"Y'know, that crazy bitch who walked into Professor Bang's class with her boyfriend this morning."
