Carmen the High-Performance Urinal
Johanna's idiotic face made for perfect fap fuel. As for Carmen the toilet, I've never tried hands-free masturbation in a urinal myself so I wouldn't know for sure, but drinking piss has gotta be tough. Not because it's dirty or turns your stomach or anything like that. You have to gulp down that steady stream without spilling a single drop, right? Honestly, the first time would be pure skill-check hell.
But pulling it off right out of the gate like that? Looks like all the women in this world are just born with urinal talent.
"Eut, hngh! Hey! Can't you aim straight?! You almost splashed my uniform! Do you have any idea how expensive this is!?"
"No splash, no harm. But damn, you caught it all like a pro. Doesn't seem like you've got prior experience as another guy's urinal... You got a real talent for this shit, huh?"
Something on par with saying, 'You got a knack for being a demon lord, don't ya?'
"Wh-what the hell?! What kinda talent is that supposed to be!"
"Hey, any talent's a good talent. Ahem, anyway, good work. Feels nice and empty now. You're free to go."
"Ah..."
But when I actually told her to beat it, Carmen just blinked there on her knees. I could practically see the creative gears in her brain whirring at full speed.
"...! Hey, we're not done yet! Can't you tell there's still piss in your urethra? You gonna just leave it like that? Gross!"
Oho. Good thinking.
"Huh, yeah, you're right. Lemme see... tissue..."
"Tissue ain't gonna clean that properly! Haa... Anyway... Come here. I'll suck it out with my mouth."
"Weren't you the one bitching about how gross it was?"
"Ugh, I already agreed to be your urinal! You can't back out just 'cause it's a little nasty! Once you commit, you gotta see it through properly! Hmph, not that a commoner like you would get this noble sense of duty."
Way too chatty for no reason~ But that's what makes her character pop, so I dig it.
"S-so... If you let me suck your dick directly, I can slurp up all that piss and clean it spotless? You won't find a high-performance urinal like this anywhere else."
"Hmm, yeah? Guess I'll take you up on that."
"...!! H-hmph! Can't be helped. I already agreed to be your urinal once, right? Can't have you walking around leaking filth everywhere, so I'll do it special."
Playing the smug card even though she's doing it for her own kicks. Carmen crawled forward on her knees, pressing her face right under my dick. Then she deeply inhaled my cock scent.
"Ooooooh~~~♥♥♥ Th-this smell... So fucking rank♥ Totally filthy♥ Snuuuuuurk♥♥♥ Haaaaah♥♥ D-do you even wash normally? Spreading this nasty stench around the academy? You're out of your mind. Hngggslurp, nngooooh♥♥"
"Huh, that bad? The other pussies seemed to love it."
"Sniff sniff! Rank, rank! Super fucking rank! S-sure, there are probably pathetic sluts whose cunts twitch for this revolting stink!"
Like you, right? She hasn't noticed yet, but Carmen's lower half was desperately humping the air front and back, air-fucking like mad. Johanna-sensei did the same thing before. Pussy bitches just suck at self-control.
"But how long you gonna just sniff my dick? Weren't you gonna clean it?"
"Sh-shut up! I'm just appraising it. Commoners really got no patience, huh?"
Carmen grumbled but obediently pulled her nose away, pressing her lips to my glans. Then smack♥—she kissed it with honey dripping from her eyes. Unconscious move, but it screamed she was already hooked on my cock. Test run: Let's pop open the mind-reading window.
"Arrogant, arrogant, arrogant! How's a commoner got such a perfect cock?! This world's all fucked up! Letting a dick like this roam free? Insane! What if a celebrity like me gets hooked on it?!"
Oho. Mind reading works, so she's fully enchanted already. Par for the course.
"You just gonna keep kissing my dick? No cleaning?"
"Wh-what's the rush?! I-I'm just mentally preparing, n-no, really!"
Carmen glared daggers full of complaint, then covered my glans with her lips. Sluuuuurp~—she sucked out every last drop of residual piss without mercy. Should be done now that the stragglers are gone, but as expected, Carmen's tongue kept lapping at my glans even after.
"Mmm~ Isn't it clean now? You still going?"
"Slurp slurp, chomp—h-hold still! Feels like there's still a bit left on your dick!"
That's her excuse, but inside?
"Uwaaaaaah! This cock's too arrogant! Why's it taste this good?! Can't stop sucking! Pussy's twitching! Why's it hornier than when I masturbate?! Mom warned me about big cocks, but who expects this?! Arrogant dicks need punishment!"
Tsundere even in her head? Purebred. Was gonna use her once and toss, but might keep her around.
"Mmm~ Ah, your tongue feels too good—dick's throbbing now~ Sorry, but since you're already my urinal, be my cum toilet too."
"Mmmph!! You're such a shameless prick! Slurrrrp♥ B-but my tongue feels too good, so I'll let it slide this once! Cum toilet? Pfft, once won't hurt!"
"Ahhh, can't help itttt♥♥ Such an awesome cock wasted on this idiot owner! Needs proper management! Wasn't gonna be a cum toilet, but just this once!!"
- Slurrrrrrslurp♥♥♥♥ Jurrrrrp♥ Chomp♥ Jubbubbubblp♥♥♥ Jooooaaaahp♥♥♥♥♥ -

With permission to suck freely granted, Carmen glued herself to my crotch and bobbed her head like mad. Unexpected high-quality onahole pickup? Hell yeah... But time to cum soon...
"Lazar! Are you in here?!"
Oh, here she comes. Johanna appeared at the bathroom door, face flushed beet red. Bow-legged like she was holding in piss, fluids leaking nonstop from her thighs and forehead. Pathetic sight—love it~
Spotting me, Johanna charged over with fire in her eyes and yelled.
"What are you doing! I told you not to turn on the rotor during class! And when I checked the classroom, you weren't there—do you know how hard I looked?!"
She raised her voice like Carmen kneeling and sucking me off right in front of her was invisible. I calmly fiddled with the rotor switch in my pocket. As it shifted from max-max-max to a steady rhythm, Johanna let out a bitch-in-heat moan and clutched her skirt.
"W-wait! In this situation, right now...!"
"Ah, fuck you're loud. Can't a guy get some privacy? Why you screaming like a banshee, scaring me?"
Privacy, yeah—like playing with the rotor stuffed in teacher's pussy. Over some lame shit like that, I gotta get nagged?
"Apologize. Say sorry for yelling."
"H-how can you... Y-you're the one in the wrong, Lazar! If you'd kept your promise properly..."
I tweaked the rotor switch and commanded.
"Parade rest!"
At my order, Johanna instantly clasped her hands behind her back and assumed the position. Not a skill effect—just pussy bitches instinctively obeying a big-dick command.
"You ain't grasping the situation, teach. Did I crank the switch and ruin your class? If class is so important, just endure the vibes and teach. Why bitch at me?"
"L-Lazar! This attitude of yours will lead to serious trouble down the line!"
Johanna kept yapping arrogantly even now. But peek into her head, and it's a different story.
"H-how can he have this much charisma, this manliness. Nothing like my fiancé. Doesn't give a shit about a woman's feelings, just bulldozes with his own needs—that toughness! I wanna follow it... But no. That'd shatter the academy's order. Gotta act properly, rationally here!"
Johanna's inner self was totally smitten, clinging to her worthless teacher role. Wanna stay a teacher? Fine by me.
"So what brings you here, teach?"
"Wh-what do you mean... Obviously, I got your call for sexual relief..."
"Oh yeah? But I already lined up today's cum toilet."
"Wh-what!?"
Johanna finally noticed Carmen. How desperate do you gotta be for tunnel vision like that?
"Th-this isn't right! Lazar's Big Dick is dangerous for immature students!"
"Psh, where's the harm? Dumping cum's fine with consent, right? Isn't it?"
I patted Carmen's head. She replied with an exaggerated slurrrrrrrrp!!!—loud as hell. Clear yes.
"Or does this academy ban cadet-on-cadet sex?"
Of course not. Girls' academy. Banning guy-girl cadet sex would be the weird part.
"N-no such... Ah, no..."
"Don't worry~ Not using her pussy anyway. Just a little cocksucking won't make her submit on its own. Right?"
For a split second, Carmen's mouth-pussy service paused. Barely a moment—she shot me a sharp glare like 'Duh, obviously.'
"So basically, no playing in teacher's pussy mound today."
"Ah, no. But... But..."
Teacher spiraled into panic. Like blue-balling her pussy this hard then bailing was too cruel. Fair point, kinda harsh.
So~
"Still, I did call you, so sending you empty-handed feels bad? I'll use you for relief after all."
"...! R-right. If not the pussy mound, other parts work. For example..."
"Your dumb face is perfect fap material."
"Eh?"
"Spread your legs, hands behind head."
Johanna obeyed without grasping the point.
"You know the type I am, teach—gets off on watching sluts break pathetically. So I'll use your retarded pose as fap fuel while cumming in this cum toilet. Counts as using you for relief, yeah?"
"W-wait, Lazar. There are better ways, more normal..." Nnghyiiiiii♥♥♥♥
Ignoring her, I switched rotor tempos. She kept the pose, shaking her pussy back and forth, squirting on the bathroom floor.
"Hiiiii!! Ooh! S-stop! Stop it! That's an order as your teacher! Stop!"
Hmm, still lacking remorse. If it's that bad, just yank the rotor out yourself. Not doing it means leaving everything to me—obvious, right?
Eyes on the cool beauty teacher's disgrace, dick in the cum toilet. Mmm~ Pure luxury.
How much time till class ends~
"S-sorry! I'm sorry! I was so rude to Lazar! Please, forgive me! Forgive me!"
Too late for apologies, Johanna-sensei. Not mad anyway—getting worked up over toys is bad for my health. One simple reason I'm doing this.
It's fun.
That's it.
"Mmm~ Fun."
