Summary
     After a long morning of fun, the inevitable happened to poor Mob...
     Fortunately for him, Reigen was a stubborn man who saw this as an
     opportunity for more.
Notes
     Part two of a collection of Reimob porn oneshots that will be posted
     sporadically.
Reigen’s arms draped over Mob’s spread legs, chin resting on Mob’s bunched up
pants that were pulled down to his mid thighs. He shifted his weight from knee
to knee, the hard tiled floor making his legs sore. But he wasn’t complaining,
especially not when he was being rewarded for his endurance with such an
adorable sight.
Mob was slumped in the chair before him, still shirtless. His soft chest rose
up and down with his sated breaths, only pausing every few minutes when Mob
wriggled on the chair to make himself comfortable again. Every once in awhile
he blinked his eyes open to look at Reigen, face unrevealing of his emotions
before he shut them again and appeared to doze off.
Reigen’s mouth was still wrapped around Mob doing his job as cock warmer well.
He kept his mouth carefully slack, sealing his lips so perfectly around Mob’s
cock and balls. His jaw was sore, saliva dripping down his chin from the
extended task. Usually he’d have long been done, Mob prying his mouth off, not
wanting overstimulation. But today was different, and Reigen didn’t mind. He
was devoted to pleasing his master.
Unable to help himself, Reigen relaxed to the point that he was able to rest
his cheek against Mob’s thigh, blinking sleepily as he allows himself to shut
his eyes and solely focus on the sounds of Mob’s breathing.
The short peace was interrupted when he felt Mob’s legs shifting under him and
heard tiny sleepy murmurs. Reigen opened his eyes, keeping his cheek pressed
against Mob’s thigh while he stared up at the beauty that was Mob waking up.
The boy blinked drowsily into space, rubbing his fisted hands against his eyes
between blinks.
Mouth still enveloped around Mob’s genitals, Reigen purred happily when Mob
began petting his hair. “Good boy,” he praised, rubbing his puffed out cheeks.
“You’ve done so well.”
Reigen preened under the praise, eye fluttering with the contentment he felt
from the caressing touches. He would have been satisfied with staying in that
position with Mob the entirety of the day - even if his jaw felt like it was
falling off.
But that silly hope was destroyed when Mob began stretching, sighing under his
breath. Reigen continued to keep his tongue lolled out over his bottom teeth,
and shifted himself along with Mob to ensure he didn’t accidentally graze the
boy’s balls with his teeth.
“I don’t wanna move,” Mob whined, grogginess weighing down his limbs. His
vision was still blurry. He had to get up extra early just to be with Reigen
this morning. While worth it, so very worth it, he was still drained.
Reigen hummed around his crotch, giving him an easy attempt of a smile while
still slumping across his legs. His expression said it all, ‘Then don’t move.’
But that wasn’t an option. “I can’t, I have to get up,” he pouted.
Unfortunately the morning had finally caught up to him, and he was dealing with
the inevitable human problem that even having psychic powers didn’t cure. He
had to piss.
“Come on, get off,” Mob said, nudging on Reigen’s forehead to get him off. But
Reigen was being stubborn and refused to let go. This wasn’t helping Mob’s
situation at all, the pressure in his bladder increasing by the second.
“Shishou, I need to get up!” No amount of gentle nudges and prodding budged
Reigen, and instead he began to lightly suck on his cock in protest. And while
Mob thought it felt as incredible as always, moaning under his breath despite
himself, he had to get up now. It was beginning to get difficult to control
himself.
But Reigen was acting like a child with a new toy. So he decided to treat him
like a child. He grabbed onto Reigen’s hair and forced him to look up at him.
“I need to piss! So unless you want me to-”
Reigen’s face lit up like a firework. He looked up at him with his best “puppy
dog” eyes, humming around his cock and balls while nestling himself closer to
Mob’s thighs.
‘He wants this,’Mob realized…‘He wants me to piss in his mouth.’
“Fine then,” Mob relented, brows furrowed as he eyed Reigen with curiosity. He
settled back into his chair, spreading his legs further. “But after this we’re
going to have a talkabout who’s in charge here.”
Reigen’s expression instantly melted into one of relief, blissful peace with
the situation. He was so eager… Reigen finally released Mob’s balls from his
mouth and slipped his mouth up until only the tip remained on his tongue. He
lapped at the head tentatively, blinking up at Mob expectantly.
With the pressure in his stomach now becoming unbearable, Mob would have
expected his Shishou not to have to wait long. But he was wrong. No matter how
much his bladder felt like it would burst any second - not a single drip came
out of his dick.
He whimpered, arching his back off the sofa as he strained to release himself
in Reigen’s ready mouth. But be it from anxiety or excitement, nothing came
out.
Sensing his plight, Reigen brought a hand over to rest on Mob’s tummy. His hand
nearly covered his lower stomach entirely. It really drove in the fact that
Reigen was being dominated by nothing more than a child…
And he loved it.
Looking up at Mob to ensure he wasn’t doing anything out of hand, he took Mob’s
tiny nod as permission. He began pressing down, kneading and massaging Mob’s
full belly. The boy whimpered above him and panted heavily. He squirmed and
brought a hand over Reigen’s hand, helping him press down.
That seemed to do the trick, for not a minute later Reigen felt the first
dribbles hit his tongue. The initial warm saltiness made his nose wrinkle,
falter for a moment in his task. But he shut his eyes and took his first gulp.
“There’s a good boy, you can’t back out now… You wanted this,” he purred,
sighing in relief as he finally was able to release his stream.
Reigen whimpered at the sudden increase of the flow, but he nodded and
dutifully swallowed down every drop. Truth be told, it didn’t taste
particularly bad. It was no worse than hot water with a spoonful of salt. There
was no particular taste he could point out beyond that. And while he wouldn’t
go out of his way to prepare such a concoction at home, that fact that this
came from Mob…
He eagerly sucked at the tip and ensured not a single drop dribbled out of his
mouth. Even when Mob finished he continued to lap at the tip like a kitten
drinking milk, kissing and sucking on the head till it was clean.
Mob sighed in relief afterwards. It had felt nothing short of amazing to piss
into the warm wetness that was Reigen’s mouth, who drank up every bit so
eagerly, not having to move, knowing that his need was being taken care of.
But he could see Reigen shifting his weight from knee to knee, mouth still
wrapped around his cock. He didn’t need to voice it. Reigen’s knees were
obviously sore, they had been there for quite a while afterall.
“Thank you,” Mob murmured, sitting himself up straight on the chair. He gave
Reigen’s head a gentle caress before nudging Reigen off his dick again. And
this time Reigen complied, popping his dick out of his mouth.
“Aggghhh,” Reigen groaned, smacking his lips together. He rubbed his chin with
one hand while using the other to push himself off the floor.
Mob smiled, “I hope that was worth it,” he pulled his underwear and pants back
into place. He slid off the chair and gather his shirt, handing it to Reigen
who readily turned it back to the right side. Mob lifted his hands in the air
so Reigen could slide his shirt on for him.
“Go rinse your mouth,” Mob instructed, giving himself a once over to make sure
everything was in place. He plopped back into the comfy chair, watching Reigen
scurry over to the bathroom readily to follow his order. Mob tilted his head
back on the cushion as he waited for Reigen to return so they could get on with
their day.
We should do this again.
