"Wow, looks like it's not gonna let up." Reigen remarked looking out the window
of the office of Spirits and Such. "I don't think you're gonna be safe walking
home Mob." The rain was pelting down and the wind was fierce, an umbrella would
be useless.
"Do you really think so Shishou?" Mob asked.
"Definitely." Reigen replied. He knew that Mob had his powers, but it wouldn't
sit right with him to let Mob walk home by himself in weather like this. "Mob,
call your parents and ask them if you can stay with me, my apartment is a lot
closer than your house."
Sure enough, Mob's parents agreed and a few minutes later, after bundling up in
their coats, they braved the rain and wind. Thankfully, Reigen only lived a few
blocks away.
Even those few blocks were enough to soak Mob and Reigen's clothes under their
coats. Once they reached the apartment, they took off their soaked shoes and
socks, and Reigen directed Mob to the bathroom, so that he could get out of his
wet clothes before he got sick.
Reigen stripped off his suit jacket, and tie, but otherwise remained clothed,
dripping water onto the floor as he dug around in his drawers for the smallest
shirt he owned.
This was so sudden. He had never had Mob in his apartment before. It wasn't
much to look at, he didn't make a lot of money so he could only afford a
studio. There was no reason to ever take Mob here before.
Until now. Now where at this very moment Mob was in his bathroom, stripping off
his clothes, dripping wet, waiting for Reigen to bring him something to wear.
Reigen could feel himself sporting a semi, despite the cold. He had to calm
down!
He grabbed a sweatshirt that had on it, #1 Psychic. He was going to grab a pair
of pants, but realized that none of them would fit Mob because of how much
taller he was.
That just made him even harder. Dammit!
He knocked on the bathroom door, and Mob opened it a crack so that Reigen could
hand him the shirt. "Sorry it's just a shirt." Reigen apologized. "I'm too tall
for any of my pants to fit you."
"It's okay Shishou, my boxers should be good enough." Mob replied.
And now that image wouldn't leave his head...
He tried to ignore it as he stripped out of the rest of his wet clothes, and
dressed in his sleep clothes.
Mob then exited the bathroom and Reigen swore his heart stopped for a second.
Mob looked so flustered and shy, the shirt just barely covering his ass, his
boxers peeking out under the bottom hem, and the sleeves a bit too long.
Now his boner, that had just gone down was threatening to come back. He looked
absolutely fuckable, staring up at him with those innocent eyes, holding his
wet school uniform in his hands.
"Ah, Shishou... where should I put these?" Mob asked demurely. Reigen directed
him to the clothesline above the shower, and brought his own clothes so that
they could hang them up to dry.
"You can have the bed, I'll take the couch for tonight." Reigen stated once
they finished.
"Shishou...that's not right, it's your home and I'm imposing." Mob protested.
"No, Mob, you are my guest." Reigen insisted, and Mob relented, reluctantly.
Mob curled up in Reigen's bed, swallowed up by the covers and pillow, looking
small and innocent. Reigen sighed.
He really needed to tamp down these horrible thoughts he was constantly
having...Mob was an innocent child, he deserved better.
Reigen grabbed a pillow and a blanket from his closet and headed to the couch.
He settled himself onto it, closing his eyes, ready to fall asleep, trying not
to think about the young boy sleeping just a few feet away.
~*~
Mob spent more time with Reigen more than anyone else, and Reigen was handsome,
kind, and smart. Mob couldn't help falling for him, lusting for him. He wanted
to slip his hands under Reigen's white dress shirt, and feel his smooth skin.
He wanted to sit in Reigen's lap, and grind on him, while burying his face into
Reigen's shoulder, leaving hickies and bitemarks all over his skin. It was
something that wouldn't go away, and he periodically woke up with sticky
underwear from wet dreams all about his shishou.
Reigen was a good man, and Mob knew that Reigen would never make the first move
on him, even if he could see the way Reigen's face sometimes got flushed around
him when he was making an effort to be particularly seductive that day.
Mob had been waiting, biding his time trying to find the perfect moment to make
a move when the storm happened and had given him the perfect...opportunity.
Now he was lying in Reigen's bed, wearing only Reigen's shirt and his boxers,
surrounded by his scent. He was rock hard underneath the blankets, it was like
a dream come true.
He could hear his shishou's breaths even out as he fell asleep, but Mob laid
there, wide awake, his heart pounding. This was the moment that could give him
everything he wanted. All he had to do was get out of bed. It would be better
than anything he had ever imagined, better than all those times when he was
home alone and he let loose with his powers, using them to push a dildo in and
out of his ass, imagining that it was his shishou fucking him.
He just had to get out of bed.
He tiptoed across the room to where Reigen was resting on the couch, and Mob
could see his erection tenting his sleep pants. Mob's own dick twitched at the
sight.
He wanted it. He needed it. He had been pining, and lusting, for so long, and
now that he had Reigen right here in front of him, so vulnerable, and clearly
needing some... attention, how could he resist?
He stripped out of his boxers and straddled Reigen, grinding his ass on
Reigen's dick. He could feel Reigen shift underneath him, could hear him moan
quietly.
It was him, causing this, making his shishou moan like that...it was all him,
not a pretty girl, or a porn video, but him,and Mob was proud of that. He
needed to hear more. Mob pulled Reigen's sleep pants down and grinded harder,
rubbing his slicked up entrance on Reigen's cock.
While he was in the bathroom, changing into the shirt that Reigen had given
him, he had searched and found a bottle of lube in the shower. He had used that
to slick himself up, he wanted to be ready and willing for his shishou.
"Unnnn....Mob." Reigen moaned.
Mob?Reigen was dreaming about him! Shishou wanted him! He wasn't just imagining
things!
He reached down and pushed Reigen's shirt up so that Mob's dick was touching
Reigen's soft, bare skin. The tip was leaking precome and it was starting to
smear all over Reigen's stomach.
Mob was about to starting stroking himself when Reigen woke up.
Mob froze. He hadn't thought about this! Sure Reigen had dreamt about him? But
that didn't mean he wanted to act upon those fantasies, and Reigen was a good
man.... would he push him off in disgust?
"Mmm... Mob." Reigen reached towards him and pulled him down for a sloppy kiss.
It was Mob's first.
"You look so cute like that in my shirt, so fuckable." Mob couldn't help but
blush.
"Shishou..." He muttered embarrassed.
"This is so hot... best dream ever." Mob could hear Reigen mutter as he
peppered Mob's skin with kisses and nips.
Oh... Reigen thought he was dreaming. Mob held back a smirk. He could work with
that.
~*~
Reigen sat up and laid Mob down on the sofa. He crawled in between his legs so
that he could get at what he really wanted. He lifted his shirt that Mob was
wearing, up so that his dick was visible. The fact that Mob was wearing his
shirt and nothing else still got to him.
He started with kissing and nipping at Mob's inner thighs. He could feel him
squirming. "Shishou..." Mob whined.
"Shhhh...I'll take care of you soon okay." Reigen reassured him. He couldn't
help but tease Mob at first, and besides, he had to leave his mark on him.
After a few more sharper bites to the soft creamy skin of Mob's thighs, Mob's
hands tangled into his hair and tugged. "So impatient." Reigen scolded lightly,
but he acquiesced and moved to start licking at the head of Mob's dick, tasting
the precome that oozed from the slit. When he gave large licks over the vein on
the underside, Mob keened and Reigen felt the heavy presence of Mob's power.
He reached under Mob, and was just going to tease at the rim of his ass, when
he felt that it was lubed up already.
He stopped mouthing at Mob's cock and looking up at him. "You got yourself
ready for me?" He asked, surprised.
"Yes... I wanted to make it good for you Shishou." Mob replied, softly. "Please
hurry Shishou, I-I want you inside." And how could Reigen say no to that?
He slipped a finger inside of Mob, then another, stretching him out. Mob was so
small, he didn't want to hurt him after all.
He could hear Mob panting at his ministrations, before he slipped a third
finger in a reached deeper in order to find that spot.
"Ah!" Mob moaned loudly when Reigen finally found his prostate.
Reigen withdrew his fingers and Mob whined. "Shishou..."
"One second Mob." Reigen shushed him. He grabbed Mob's legs and hiked them up.
He knelt in between them and lined up his dick with Mob's stretched out hole
before pushing in slowly.
He was so tight! Mob's ass felt like heaven around his dick. This was
definitely the best dream yet.
When Reigen was finally fully seated within Mob he gave him a minute to adjust.
Reigen couldn't help but stare at the pretty picture Mob made underneath him,
shirt all bunched up, hair tousled, face flushed.
"You can move now Shishou..." Mob said. Reigen immediately began thrusting,
starting out slow but working up to a faster pace.
"You want my cock huh?"
Mob nodded furiously. "You fill me up so good Shishou, I need you!"
"Apparently I'm not filling you up enough if you can still talk." Reigen
remarked and began thrusting harder. "That better you little slut? You getting
what you want now?"
"Yes! Yes!" Mob exclaimed. "More!"
Reigen stopped talking then and fully focused on giving Mob the maximum amount
of pleasure. He reached between them and started stroking Mob's dick. The angle
was awkward and it was hard to keep up.
Why was it hurting? Reigen wondered. Oddly realistic dream, he thought.
He could tell that Mob was close to coming, his legs were trembling.
"Shishou!" Mob shouted in ecstasy.
"Mob...so good. Your ass was made for my dick. Taking me so well. Come for me."
Reigen demanded. He made sure that he was giving just the right flick of his
wrist and rubbing his thumb over the head of Mob's dick to give just the right
amount of stimulation. By this point Reigen was leaning over him, and Mob's
arms were wrapped around Reigen's neck.
Mob's ass spasmed around his cock and sure enough, Mob came all over his hand.
Right when he did Reigen jolted in surprise when Mob sank his teeth into the
meat of Reigen's shoulder. The pain was sharp and all too real.
This didn't feel like a dream anymore.
But he was so close... Mob's ass spasming around his cock just brought him
closer to the edge. It had to be a dream, something like this would never
happen for real...right?
He kept thrusting, bringing himself closer and closer to orgasm. Mob, beneath
him, seemed to be floating in a blissed out high. He looked at him with hazy
eyes, before reaching to rub at one of Reigen's nipples.
"Are you almost there Shishou?" Mob asked in a breathy voice.
"So close..." Reigen grunted.
"I want you to fill me up." Mob said. "I want to feel your come inside of me,
marking me.... making me yours. I want to be yours, Shishou."
Reigen was spurred on even more by Mob voicing his desires.
"Say my name." Reigen demanded. He wanted to hear it from Mob's lips.
"A-Arataka, please." Reigen had never heard Mob say his first name before,
especially as breathless as that. It was too much, and after a few more sharp
thrusts he stilled, coming inside of Mob, with a long drawn out moan of
pleasure.
He panted, worn out from the exercise, he hadn't had sex in quite some time,
and his lungs were not used to this much exertion. He really needed to cut down
on the smoking.
His arms were trembling and he knew he couldn't hold himself up for much
longer, so pulled out of Mob and sat up, bringing Mob with him.
He held Mob close to him, and as the seconds ticked by, the sinking feeling of
dread consumed him. The silence in the room was poignant, and Reigen had to
break it.
"This is real...isn't it?"
"Yes, Shishou."
Reigen sucked in a sharp breath. "How-how could you let me do that to you Mob?"
"I wanted this, Shishou."
"You're a child!"
"I know how to say no, Shishou, I can fight back. But I didn't do any of that,
because I didn't want to." Mob replied. "You're not a bad person, I wanted
this. We're so good together, why would you ever want to stop? I want
more...and I know you do too Shishou."
Mob was right. Though Reigen knew he had been a bit forceful Mob was so much
more powerful than him he could have stopped him in his tracks immediately if
this was truly something he didn't want.
And now Mob was explicitly telling him that he wanted more.
He had already done what he shouldn't have.
Reigen pulled away from Mob and looked at what he had done to him. Mob grew
flustered under Reigen's gaze, his hands covering his mouth, nervous. He was
still wearing Reigen's shirt, which hung off his shoulder, revealing a bite
mark. There were more bite marks and hickeys along Mob's inner thighs and
Reigen could see them smeared with his come and lube that was dripping out of
Mob's ass. And was Mob hard again? He was insatiable.
Reigen couldn't judge though, the sight of Mob in this state was extremely
arousing.
"You're right." Reigen said. "I do want you. In fact - " Reigen leaned in
closer to Mob to the point where he was whispering in his ear. "- I'm gonna
fuck you all night. You want that?" Reigen asked.
"Yes."Mob replied, desperate.
Reigen was going to hell for what he had done, and he knew it. But right now?
He didn't care anymore. If he was destined for hell, he might as well enjoy the
ride down.
