Natsuki-san steps obediently through the open door.
"...C-Can you take it easy?"
"Well, I guess I'll leave it to Natsuki-san today then?"
I go in with her and close the door behind me.
"Okay. Leave the lid on and sit down?"
"O-Okay."
When she gets serious, she has a cute habit of saying "Okay."
"Well, I'll take care of you, Natsuki-san, my sex friend?"
"Don't keep repeating things!"
Even as she complains, her hands are on the pelt of my pants.
She quickly undoes them and puts her hands on the hooks.
It's smoother than last time. I'm impressed.
"Huh?"
"Wh-What is it?"
"You've got a good memory."
"Shut up!"
I forcefully pull down the zipper.
"...Today, it's, um, small."
"That's hurtful."
"Eh, no, that's not what I meant, it's..."
"Repeat after me."
"Eh?"
"Not small. Say it's not erect."
"B..."
Even though he has a fully exposed dick in front of him, Natsuki-san bows her head at such verbal abuse.
So cute.
"B...it's not erect."
"So, what do you think you should do?"
"Uh...um."
Last time, Natsuki-san had it thrust into her mouth before she had time to think.
This time, she has to think up the steps herself, so she's confused.
"...I don't know. What should I do?"
"Well, let's try putting it in your mouth for now."
"O-okay."
Natsuki-san casually stuffs the soft penis into her mouth.
"Now then?"
The blonde delinquent girl looked up at me while mumbling.
Perhaps her long hair was getting in the way, but the way she tucked it behind her ear with her fingertips was really sexy.
"...Moga!?"
My son reacted to Natsuki's erotic move.
"Ugh!? Cough cough!"
Natsuki's mouth was pressed against the instantly erect penis, and she coughed in pain as it hit her throat.
"Natsuki's so horny that I got hard right away."
"...I-I made him get hard."
"Really?"
"...Good. I can take the lead."
I see.
I see, I see.
Due to the structure of the genitals, sexual intercourse is impossible unless the man is erect.
In this world, no matter how much a woman wants to have sex, rape is not even possible unless the man is in that state.
And now she is thrilled that she has succeeded in getting the man in the mood, in other words, that she has managed to get him erect.
It may be something like a woman's pride in this world.
In terms of the man from her previous life, it would be like making him cum with a caress? It must be a similar feeling of accomplishment. Natsuki is very pleased.
"That's right. I got an erection because you're horny, Natsuki. Are you happy?"
"N-no, it's not like I'm happy! If you can't take the lead, you're not cool as a woman!"
"It's not like I particularly like girls who try to act cool like that."
Of course, I do welcome the proactive aspect of it.
Natsuki seems a little angry when she says she doesn't mind taking the lead, and she looks a bit sulky.
"Yeah, that's right. What you like is a masochistic woman who listens to whatever you say."
"That's right. As Natsuki says, I think I'm more of a sadist, right? Will you listen to my next request from me?"
"... What is it?"
I thrust my erect penis towards Natsuki.
"Aah, do it?"
"... Yeah."
Natsuki obediently opens her mouth, welcomes my penis with her outstretched tongue, and slowly swallows it. It's really erotic.
"Today, Natsuki, try moving. I'll just stand there."
"Ehh... hahaha"
"It's okay to move slowly at first, but try moving more widely?"
Natsuki slowly moves her head while replying in a pained voice.
It's a monotonous stimulation, but Natsuki's body temperature is transmitted to me along with the slime of her saliva, and an indescribable pleasure runs through my entire waist.
For a man, visual information maximizes the pleasure he gets.
The sight of a delinquent girl's blonde hair swaying beneath him in the men's restroom is the ultimate stimulation.
"Why don't you try using your tongue too? While thinking about how to make me feel good?"
"Ngh...yeah...hmm..."
And she's so obedient during sex.
Her rough tone from a moment ago is gone, and she obediently follows me. It's just too good.
Natsuki-san starts to move her tongue.
A different kind of pleasure is coming from my penis.
It's like she's licking it haltingly.
After pulling my penis out of her mouth, Natsuki-san asks anxiously.
"Hey. Is this okay?"
"Yeah. It feels great. Thank you, can you continue?"
"...hmm...hmm..."
Natsuki-san, flushed, looks up at me with wet eyes and swallows my penis again.
Every time Natsuki moves, drool drips from the corners of her lips, wetting the floor and her skirt.
The lewd sight and the feeling of Natsuki's tongue are very pleasant.
I could probably get off like this. But I want something a little stronger.
"Try pursing your lips like that and sucking?"
"...Hmm"
With a tight feeling, Natsuki's lips stick to my penis.
"That's right. Try moving it again like that."
"...!?"
Natsuki stops moving, surprised by the loud noise coming from her mouth.
"What's wrong? Keep going?"
"..."
After a while, Natsuki sucks on my penis again and slowly moves her head.
Boo...Boo...!
Although it's quieter than before, the lewd sound of air and saliva echoes in the toilet stall.
Seeing that I didn't say anything, Natsuki continued moving with a relieved look.
Bam...Bam, Bob...Bam...!
Perhaps she was getting used to it, and her strokes got faster and faster.
"That feels good. That feels really good, Natsuki. Keep it up."
"Hm...Hm!?"
The indescribable pleasure made me time my hips to thrust forward.
Natsuki groaned in pain as my penis suddenly entered her throat.
"Cough! Cough!...Hmmm, hmmm."
But she immediately took the penis in her mouth and started moving.
She was just trying her best.
It's not like the woman would find this just painful or pleasurable, and it's not even fun.
It's just something the man does because he wants it.
So I stroked Natsuki's head to show my gratitude, and she stopped moving for a moment.
"Huh? What's wrong?"
"..."
Blushing, she sucked my penis harder than before and started moving violently.
It's not exactly a carrot and stick game, but Natsuki-san is easy to get into when you praise her after she's been mean to me.
She's really cute.
I'm starting to get excited, too.
Slurp... slurp...!
The amount of saliva dripping from Natsuki-san's mouth is increasing, making it sticky.
Looking at her face as she frantically moves her head, I suddenly feel the urge to ejaculate approaching.
I don't say anything, but ejaculate with all my might.
"...Hmm... mmmmm!"
Semen is released over and over from my pulsating penis.
Natsuki-san catches it in her throat and tries to let go, so I quickly hold her head down.
"Muuuuuh!"
Seeing Natsuki's face as she looks up in protest with tears in her eyes, I get excited and thrust my penis deeper.
"Nngh"
Seeing Natsuki's pained expression, I continue to ejaculate.
Soon.
"Fu. I came so much. Thank you, Natsuki... Natsuki?"
"... Pua"
When I let go of Natsuki's head, Natsuki spat out my penis from her mouth and looked at me with hazy eyes.
Her eyes were facing me, but she was limp as she sat on the toilet seat and seemed unfocused.
"It must be amazing to cum from having your mouth violated huh?"
It must be the effect of "Climax Ejaculation".
Despite the fact that she was coughing so much, her eyes were still ecstatic and staring up at me blankly.
It's a stupid-sounding skill, but its effect is still outstanding.
Thanks to this, a tough delinquent girl fell so easily after just two oral sessions.
It seems to be addictive too, so it must be the worst for the person on the receiving end.
But it's not without problems.
"Natsuki-san, can you stand up?"
"Ah... uh."
Natsuki-san shook her head weakly.
She opened her mouth to say something, but a cloudy white saliva dripped from the corner of her lips.
--Slurp.
Natsuki-san sucked it up.
She swallowed my semen with a throaty gulp, and her expression became ecstatic again.
It was as if my semen was a bad drug. Well, she had come.
"I guess I won't be able to move for a while."
Seeing Natsuki-san still in a trance, I sighed and waited for her to recover in the small private room.
In the end, no one came into the bathroom, but there were several noises coming from the women's bathroom next door, so it might be best to be careful when entering and leaving.
