Summary
     Reigen sexts Mob in the middle of math class
Notes
     Reigen is a bad person in this fic for the purpose of boners
On a day like any other, Mob and Reigen were talking in the office.
"But Master," Mob said, eyes downcast, cold sweat droplets beading on his face,
"I can't use my phone during class. It's against the rules. The teachers..."
"Nonsense," Reigen replied, clapping him on the shoulder. "Ours is a special
case, naturally. So you should just use your powers so that no one notices
you're using your phone." He jabbed his right index finger into mob's face.
"You can do that, right?"
Mob turned his head slightly away, but there wasn't really any direction he
could escape to. "I... I suppose I could, Master... I could probably create
some kind of illusion."
"There you go, Mob! I knew I could count on you." Reigen beamed at him and
tightened his grip on his shoulder.
"But... Isn't that a bit of an abuse of my powers?"
"Not at all! It's very important for our work that I be able to reach you at
all times." Reigen released his grip and patted Mob's shoulder a few times
before turning away from him. "I'm your master, and I say it's okay, so do what
I say, all right, Mob?"
And so, when Mob's phone buzzed in the middle of math class the next day, a
familiar cold sweat overtook him and the bottom of his stomach filled up with
lead, but he gingerly dipped his fingers into his pants pocket, glancing around
nervously as he did so. He had learned to extend his psychic aura around
himself in a way so that no one around him would notice any sights or sounds
coming from within, but it still seemed a bit surreal. He could see his own
aura, of course, but he could also ignore it if he chose too, and if he did
that... It looked like an absolutely normal day in class. The teacher was
writing formulas on the blackboard that made absolutely no sense to Mob; some
of his classmates were scribbling notes while others in the back were giggling
and whispering across the aisles in low tones. If he turned his head he could
see Mezato, her math book open but ignored on her desk while she tapped her
pencil on her reporter's notebook instead.
A totally unremarkable day.
Mob took a long breath and flipped his phone open. Even though he knew no one
should be able to see it, he kept it in his lap instinctively, hidden from the
teacher's line of sight by the top of his desk.
He had several messages from Master.
Mob, are you in class right now?
Reply when you get this message
Where are you, Mob?
Mob took his phone in both hands as he typed out his reply: I'm in math class,
Master.
Math? What a boring subject
Are you bored, Mob?
I'm bored. There haven't been any clients all day
The sweat on the sides of Mob's face got a little thicker, and the sick feeling
in his stomach grew. When Master got bored like this... Mob thought about what
Master had said, that he needed to be able to text him in class for work
reasons, but this obviously wasn't work-related at all. Maybe... Maybe if he
just said something like that, Master would realize he was right and let Mob
go...
This is what it's like, Mob, being here bored and all alone without you to take
care of me.
Mob froze. The picture below the message showed Master's hand wrapped around
his erect dick, pulled out and held in front of the open fly of his slacks. It
was a sight Mob was intimately familiar with, from so many times doing his duty
to take care of his master. But sending this to him here, in class...
See how hard I am, Mob?
It's just not the same doing it myself
I need your hot little mouth wrapped around me, sucking me down
Wanna fuck your pretty face, Mob
Mob's hands trembled. He could just close the phone. He could close it and turn
off the message notification, and shove it back into his pocket and later say
that something had happened, the teacher had called on him and he had to drop
his psychic illusion and put his phone away. Master Reigen would never know the
truth. There was no way for him to know.
Mob
I know you're there, Mob
It's only polite to reply to someone when they message you, Mob. Especially
your master
I thought I taught you better than this.
But the teacher didn't call on him, and Mob didn't put his phone away to
pretend he had. Yes, he sent back. Just that.
Good, Reigen replied.
I want to know you're thinking about me when I'm thinking about you, Mob
I'm thinking about you right now. Thinking about how I can't wait until you get
done with school and come over here. Thinking about whether I want to fuck your
mouth or bend you over my desk and mess up your tight little ass today.
Are you hard, Mob?
He was, to his extreme mortification. But if he ignored it, it would go away.
He knew this from plenty of times with Master. Sometimes, of course, Master
wouldn't let that happen. Sometimes he touched Mob and despite Mob's best
efforts to shut the feelings out, he couldn't ignore how good it felt. Tears
would build up in his eyes and his chest would feel tight and hot, but he'd
come in Master's hand all the same. And the whole time Master would be holding
him close, whispering in his ear, "It feels good, doesn't it, Mob? You like it,
don't you? You like the way I make you feel. Such a little slut, giving it up
so easily the instant someone puts a hand on your cock... So much practice
keeping yourself shut away from the world but the second I touch your prick
you're as hard as a rock, squirming and pliant and moaning, aren't you... Such
a chore, Mob, making me take care of you like this, being a needy little whore
all the time. You're lucky I'm so generous. You should be grateful I'm giving
you this attention, and always remember to fill your proper role... Ahh, yes
Mob, you like that, don't you? You fucking slut..."
But this time, Master was asking. He wasn't going to ignore it. On the other
hand, he wasn't here. He couldn't see Mob, couldn't know for sure the state he
was in. Mob could ignore it and wait for it to go away. No, he messaged back.
Ah, Mob. Lying? I thought you were a better person than that.
Every muscle in Mob’s body tensed up.
But it's okay, Mob. I'll forgive you. I understand you're just nervous.
To make it up to me, I want you to take it out and send me a picture back
Mob's fingers felt sluggish on his phone's number pad, like they wouldn't move
properly. Somehow he managed to reply, But Master, I'm in the middle of
class...
Mob. Please.
This is a good opportunity for you to practice fine control of your powers. As
long as you maintain that, no one will be able to see what you're doing, right?
Now be a good boy and send me the picture
Mob set his phone on top of his desk in order to free both his hands. He was
extra conscious of the feeling of his powers extended around him as he looked
around his room, glancing at his classmates' faces to see if any of them were
looking at him. None of them seemed to be paying any attention to him at all.
And yet, he still couldn't shake the feeling that all of them were looking at
him. His hands fumbled on the button of his pants, and the sound of his zipper
felt like the loudest thing he had maybe ever heard, but still, no one looked
his way. Not even when he pulled his dick out, now fully erect and warm against
his cold and clammy hand. He picked up his phone again with his other hand and
took and sent a picture as quickly as he could. He couldn't keep the camera
still, and it came out all blurry.
Mob, came Reigen's nearly instant reply, what is that? I can't see anything at
all
Don't do things half-heartedly. You’re better than that. Come on now.
Try using your powers to steady your phone if you're having trouble taking a
good picture
So Mob did, and resent the much clearer picture. Reigen replied, Very good,
Mob, and Mob's body flooded with exhausted relief. He had passed the test. He
started to tuck himself back into his pants (as usual, if he ignored it it
would eventually go away), when his phone vibrated with another message.
Now, I want you to touch yourself, Mob
Mob froze again. The relief was gone. He felt like he was teetering on the
brink of an emotional explosion. How... How...
His phone buzzed several times in rapid succession.
Calm down, Mob
Even from here, I can tell you're freaking out
Listen to me, Mob. It's okay. Take a deep breath. You're a good boy, Mob.
You're just doing this to help me out, remember? And I'm helping you out.
Forget about being in class.
You're always so good at doing what you're told. You're an ideal student, that
way. I really appreciate that about you, Mob.
Now, there's nothing to panic about here. I needed my student's help, so I
reached out to you, and now you need my help too. So let's help each other,
Mob. That's all we're doing. It's okay. Just let me help you.
Mob breathed. Of course, Master knew best. Of course everything was alright.
This wasn't that different from what they did together in Master's office. All
he had to do was keep control of his powers and no one in class would know what
he was doing.
Are you okay, Mob?
I'm okay, Master, Mob replied.
Good. I was worried about you
You can block sound with your powers too, can't you, Mob?
Of course, Mob had already been blocking sound this entire time. He was about
to send his reply, but before he could hit the send button, his phone vibrated
again. Despite having mostly calmed down, Mob still jumped slightly, then
noticed that the vibration was ongoing. Master was calling him.
It was okay. Master had told him everything was okay. And no one could hear
him.
Mob's anxiety still ticked up a few clicks as he hit the button to accept the
call. "Master?" he whispered. Even though he knew no one should be able to hear
him, it still sounded to him like he was shouting. He kept his eyes locked on
the teacher's back at the front of the room, expecting him to drop his chalk
and turn around to glare in Mob's direction at any moment.
"Ahh, Mob," said Reigen. His voice sounded slightly distant, and he was
breathing heavily. Mob realized he must have him on speaker phone. "Good boy.
Are you touching yourself yet?"
"I-I..." Mob looked down at his erect cock. "I-I'm holding it, Master."
"Goood," Reigen crooned. He paused, and Mob heard Reigen's panting breaths and
the slap of skin against skin. "Put me on speaker phone on your end too. Good,
that's right. Now I want you to stroke yourself, Mob. Wrap your hand around
your dick and jerk off."
Mob's breath hitched in his throat. He shifted his hand to circle his dick and
began to move his grip, feeling the loose foreskin bunching and stretching
under his fingers. He squeezed his eyes tight and focused on the sound of
Reigen's voice. He felt very warm.
"Are you stroking yourself, Mob?"
"Y-yes, Master."
"Good." The sounds of Reigen jerking himself off on the other end of the line
picked up in tempo. "I want you to imagine it's my hand wrapped around your
dick. And your hand is wrapped around mine. Can you do that, Mob?"
Somehow, he could. He wasn't touching his own dick, but jerking Master off at
the same time that Master was touching him. Mob's breathing got louder and more
unsteady, and he let out a broken moan. "Master..." he cried out, "Please..."
"Mob. Fuck, Mob. Your hand feels so good wrapped around me, ahhh, so much
better than just doing it here by myself. Fuck, Mob, I'm close. I'm so close.
Are you close, Mob? I want you to come at the same time as me, do you hear me?
Because you're holding my cock, and I'm holding yours, so when I come, you come
too, got it? And not before that. Fuck, Mob, yes, just like that... Now tighten
your grip a little and stroke even faster. Yes, that's right. You're so good at
that, you're such a good little slut..."
And then Mob was coming, and Master Reigen was coming too. As Mob suddenly
blinked into awareness of the world outside him again, he realized in a panic
that he was in class, and his powers, his powers...!
His powers were about to let the protective aura around him fall apart, but he
caught it at just the right time, desperately firming the barrier around
himself again as he bent over his desk, panting, his softening dick still out
in his hand under the desk, cum sticky on his fingers.
"Mob?" Reigen was saying on the phone. "Are you still there?"
"Y-yes, Master," said Mob, pulling himself upright. "I'm here."
"Good, Mob. You did very well. All right, I'm going to let you get back to
class now. I'll see you later."
And Mob finally felt relief course through him as Master hung up the call. That
hadn't been too bad, after all. He'd made it through, and it wasn't really
anything that different from the usual. He could withstand this.
Mob looked down at his messy hand and cock, and began to flare his powers in
order to clean himself, when his phone buzzed once again. He froze, and picked
it up with his free hand. More...? Surely Master couldn't need him again so
quickly... Although maybe there was something he needed to remind Mob of.
Ah, Mob. I forgot to say before hanging up
You aren't permitted to do anything to clean yourself up. Just tuck yourself
back in as-is
If you need to wipe your hand on something, wipe it inside of your underwear
I'll know if you've disobeyed me when you show up here after school
Show me what a good student you are as always, Mob.
He walked around school for the remainder of the day with the sticky and then
crusty mess in his pants. It was hard not letting it distract him, but that was
surely Master Reigen's plan, to teach him focus and discipline through enduring
uncomfortable situations.
Though it could be difficult, Mob always tried his very best to be a good
person and a good student.
