Summary
     Shigeo believes he is the protagonist of his own story, but when
     Reigen is murdered and the perpetrator gets away, his psychic powers
     start to rebel against him. As Mob's disempowerment continues to
     haunt his staggering steps, he meets an evil spirit who offers him
     help... at a very high price.
Notes
     I hope you all enjoy Mob's suffering...
See the end of the work for more notes
Reigen would always say to Mob that he was the protagonist of his own story. It
was once the truth, but not for a story that stopped mid-word.
It began to be untold with his master going missing. The phone rang and his
father answered before covering his mouth. He told his son that the police had
been in touch, and they found Reigen's body. His body? Mob had asked. His
father apologized and hugged the boy to try to calm him down.
The man was found by the police dead in an abandoned storehouse, gored with
knife wounds. The information came to Shigeo through the news. When his parents
caught him looking over their shoulders at the television they switched it off.
The funeral was the day after the wake. Shigeo's parents prayed in front of
Reigen's portrait. He followed their example, not really taking anything in,
floating on the wave of shock.
Where had Shishou gone? The mattress springs on Reigen's bed waited to be
rocked all this time. Soon Shishou would come back to hug him and bury his nose
in the crown of his head. They'd go to his apartment and sleep together. They'd
waited so long but Shigeo was ready from the beginning. Shishou said "We won't
touch until you grow more."
The reality hit him before long. There was no reason to grow. He could be
nothing, at least. The clean-slate mindset would only get him so far, however.
Mob's body grew up, and without Reigen's love, his needs grew terrible.
Robbed sensations can return to the body, causing little bursts of feeling that
make one desperate. Mob lay in his bed blissfully unaware of this nightmare
until the moment came. His eyes opened and he shuddered; it felt like an
opening of wings inside him. They beat the air like tyrants, turning Mob's
lonely bed into a sweaty prison. He was suspended on the brink of orgasm and no
matter what he did, he couldn't finish it.
It hadn't felt this way since the first time he kissed Reigen. The pain would
no longer be ignored in the guise of pleasure. Shigeo had been denying his
emotions, unable to approach grieving. And now looking at himself writhing with
discomfort, trying to get off but unable to cross the bridge, it was the straw
that broke the load. He sobbed into his pillow and prayed it would go away, but
it carried on without pause for months.
The spasms were hard jolts of arousal that weakened his thoughts and shortened
his breath. The more hours passed in his waking days, the more the spasms made
Shigeo feel unbelievably ashamed. No one would happily tolerate this taint.
Soon, Shigeo started to lose sense of his reality.
This story was not his, just as the orgasms were not his. After several doctors
had seen him with no conclusive answers, it probably meant that he would live
with it for the rest of his life. Neither a smile from his brother or time
spent in nature was a sincere moment to be simply felt; everything was devoured
by the ache.
This problem could only be fixed one way, he decided. He would find a partner
that reminded him of Shishou and let him take his virginity. Only Reigen's love
could cure him, but was he truly helpless now that the man was gone?
The man he saw in the library had a similar look to Reigen. He had short blond
hair, messy bangs, a square jaw. He even dressed in a suit, although his was a
darker gray than Reigen's. Mob didn't know that the man was interested until
one day he bottled up his fear and approached the stranger. His nervous spasms
made him tremble and struggle to walk to the stranger's desk. The man looked up
and adjusted his reading glasses; he was quite old. Mob shuffled his feet and
introduced himself.
"Hello, sir. M-My name is Shigeo. Can I talk to you briefly?"
"Are you okay?" asked the man, putting down his magazine.
"Uh..." Mob gawked and tried to keep his reactions small.
"Are you... looking to make a few extra dollars?" the man asked suddenly.
Mob could hope for no better consideration.
He went home with the man, who's name he didn't bother remembering. All of his
world was distorted. Mob's shame brought him out of his selfhood and into a
state of being that was alien. A story like this needed a character who was
degraded to the point of oblivion, he surmised.
A bittersweet victory turned into a horrible nightmare, however, when Mob
started to make physical contact with this stranger. As the man took off his
shirt and lewdly ran his hairy hands over Mob's sensitive chest, he realized
that he'd made a mistake. Shigeo thought he'd accepted becoming someone else's
sex doll, but it was far too early to be rushing something like this.
"Wait." he said hesitantly. The man responded curtly and told him to hold still
and stay quiet.
"No, I don't like this. I changed my mind." Mob stated with worry, trying to
avoid the man's lips.
"It's too late." said the stranger as he brought out of his pocket a small
knife and placed it over Shigeo's throat.
"Lie down." he said.
Shigeo whimpered and sat down on the bed, crawling backwards. The stranger
shrugged off his jacket and opened Mob's legs. Mob wanted to use his powers to
defend himself, but ever since the spasms started he couldn't control them. He
had no idea if they were lethal enough to kill the man. He couldn't be a
murderer. Better be a sex doll than that.
After that it all went downhill. The stranger raped him, and when he was
finished, he spat in Mob's gaping hole.
"Whore." he said, and kicked him out of his house.
Nothing had ever humiliated Mob so much. He was dead on the inside now, walking
through life like a marionette, dancing to whatever tune his story made for
him. Reigen was the only one who would understand. But his life had been stolen
and the thief got away. Shigeo never even had a chance to contemplate a fantasy
of revenge.
What was he trying to fix anymore? The question left him lost. There was
nothing holding the future together.
He thought about the rape while standing over the edge of a bridge. At the
bottom, after a sharp distance, was the dark canal. He could drown in that
darkness.
As Shigeo thought about jumping off the edge, an icy gust of wind passed him,
whipping his raven hair around his forehead. He patted the annoying locks so
that they were neatened. But then he noticed that he was trying to fix his hair
even though he would be dead in the next moment. Bubbles of bitterness erupted
in his mouth. He felt the bile rise - the distance to the water gave him
vertigo.
As the world rocked beneath him, a hand grabbed his shoulder; a hefty hand with
broad fingernails and thick knuckles. He stared at the hand idly before
realizing it wasn't death welcoming him to the next world.
Another hand found his opposite shoulder, holding him back against the fence.
The owner leaned near his ear. Dirty locks of hair scratched Mob's neck.
"Are you sure you want to do that?" the deep voice whispered, intimately close
to his round cheek.
When Mob lacked a response and stared at that hand mutely, the voice behind him
restated itself "You still have work to do."
"What work?" Mob said, feeling uncomfortable in his gut, tingles shooting
through his chest. Did this person want to exploit his body too?
"The problem you wanted fixed long ago is still left untended." said the deep,
smooth voice.
"Aren't you a spirit? I'm sorry, but what does my problem have to do with you?"
asked Mob.
"I know what you struggle with right now. Your discomfort is palpable through
your aura. It doesn't have to be that way, you know."
"Okay. How can you help me?" Mob questioned him skeptically, letting his
frustration show.
He turned around and held onto the arm of the fence, breaking contact, and
stared up at the stranger. He was a tall man with high cheekbones, flat, oily
hair and an almost simperingly sardonic look. His age seemed unclear, as his
eyes showed exhausted lines but his whole face was like a young adult's. The
man's lazy gaze on Mob was oddly penetrating and his smile was easy.
"I can help you." said the gaunt stranger, observing Mob, "I see you really are
desperate. Those spasms must make normal life impossible for you. Would you
like those problems to go away?"
Mob sighed as the spasm rocked his whole body. "Do you know how to make this
pain go away?"
"With a civil agreement between two partners, Shigeo." Mogami explained, "These
spasms have prevented you from acting of your own free will. With my help,
you'll be freed, finally, to pursue that man's killer."
"How do you know about him?" Mob dared to ask.
"I know many fascinating things about you both." said the stranger with a slow
nod, "I haven't introduced myself, yet. Rude, I know. Forgive me. My name is
Mogami Keiji."
"Are you an evil spirit?" said Mob warily.
"Yes." Mogami replied subtly, strikingly smart in his old green jacket.
"Should I really trust you, then, Mogami-san?" the boy asked, feeling rare fear
in the presence of a spirit.
Mogami sighed deeply, holding his brow. "If you ever want to be a whole human
being again." he said, "But I can just go, now. You don't have to accept my
offer at all. You will suffer the rest of your life if you don't."
"I want help, but I don't know how you could help me..." Mob said regrettably.
Mogami chuckled and said "When your spasms become so intense you can't bear it,
I can possess your body to release you from the pain. When that's done, I'll
help you get your revenge, Shigeo. The only condition you must accept is that I
become your mentor."
He looked at Shigeo too fondly to be ignorant of his secrets. The boy said,
"What does being my mentor mean...? You're not like him."
"No, I'm not." said Mogami, "Given you don't have a master, I feel I am
responsible for stepping in. I'm the only one who can put you back in your
life."
This was the issue that Mob struggled with and it made him realize what a loser
he had become. The chance to be the protagonist again was before him, in the
eyes of Mogami Keiji.
"Very good." said Keiji as if reading his mind. This unsettling person was
strangely reassuring.
"Um... I accept your condition, although I'm not sure it's right." said Mob,
looking up at his benefactor, "Help me."
Mogami extended his helping hand. "Here."
Mob, with his weakened free arm, placed his hand in Mogami's and let the
process begin. He shut his eyes ruefully and allowed himself to be displaced.
A cloak of whispering darkness enveloped him and he flinched. Mogami forced his
soul out of his body, pushing him out through his mouth, which began to feel
foreign. Mob wafted into the air and stared down at the body that was once
completely his in this story.
Just as the realization of his possession took place, Mob saw his body totter
over the edge of the bridge. He had been standing uncertainly with the fence
for support. Helplessly, he watched as his body fell through the empty air. He
was falling down to his death.
Before the body met the water, Mogami replaced Shigeo by using his powers to
levitate himself above the disturbed surface. Dark waves swooshed around his
feet while he stood erect, proud and powerful, in Mob's skin.
"Feeling better?" he called to the little soul hovering in worry above him.
Mob could say nothing at first, totally relieved he hadn't died now that the
pain was gone. His lack of a body made physical feelings seem like abstract
ideas. He couldn't remember what the torment felt like, but he cherished his
moment of blissful ignorance.
Mogami shrewdly said, rising up, "It feels good to be inside you. Power like
this is not easily come by, now that the extrasensory arousal isn't
interfering. One could say you were too powerful."
"You promised to help me find Shishou's murderer." reminded Mob above him. The
man came over to the other side of the fence, placing his feet on the stable
ramp.
"Yes, and I will, of course." said Mogami, "However, I follow my own code. If
you disagree with the way I do things, you are always free to take control of
your body again. Your spasms will return, in that case, and as your Shishou I
will make my judgements compelling..."
He laughed, aware of the exploitation, "We'll work well together, Shigeo. I am
only here for you."
All Mob could say was "What must I do?"
-------------
Dr. Nakajima had wrapped up his session with his last client. His waiting room,
vacant of patients, quietly darkened as he walked out of the building. He
wrapped the flaps of his coat around himself and jogged through the rainy
parking lot to his car. Slamming the door shut, he breathed deeply for a
moment. Then he started his car and began driving home.
The suburban neighborhood in Spice City rolled past him. He played something on
the radio. Tapping his palms against the steering wheel rhythmically, he
acknowledged that it was all part of a distraction. A lesson, one he'd
fervently tried to unlearn, was tapping against his mind like his hands on the
wheel. It was beating in his brain.
"Nakajima." said a gentle voice from the passenger seat, belonging to a man
older than him.
The therapist was not jolted out of reverie. Instead, he sighed as if relieved.
"Thanks for keeping me company, Tetsuya."
"Of course, my friend." said the blond haired, disreputably scruffy man beside
him, "It's the least I can do, after all you've done to help me."
"Yes." said Nakajima, nodding. His knuckles were pure white. "Are you watching
the police?"
"Don't worry. They're oblivious to your identity." said his companion.
"Good." Nakajima sighed. He rapped his hands on the steering wheel again. Out
of nowhere, Tetsuya reached over and turned off the radio, silencing his
distraction.
"We're not done with our mission." he said to the nervous therapist.
"We're not?" asked Nakajima. He'd started sweating underneath his heavy coat.
The smell of blood returned - his memories showed him what he'd done in
Tetsuya's place.
"Somebody is looking for you." Tetsuya informed him, "He's helped by an evil
spirit. Alone, he's hardly a threat, since his psychic powers don't work
anymore. But with this spirit's help he'll kill you. And he's only a child."
"What?" Nakajima gasped, glancing quickly at Tetsuya. "He's not... that man's
son, is he?"
"No, he's not." said Tetsuya, "He's Arataka's disciple."
"How did you meet him?" asked Nakajima.
"I encountered him in a library." answered the older man, chuckling.
The therapist, perturbed, felt a roiling wave slap against the walls of his
stomach. "You met him by chance?"
"Never mind that, Nakajima..." Tetsuya sighed, "It's time to find him and kill
him before he does anything to reveal your secret."
"... Okay..." Dr. Nakajima exhaled, squeezing his steering wheel. Tetsuya said
"That's my boy."
His voice lingering in the therapist's head kept him driving, passing his home
and family, to commit another murder.
----------
The freezing wind and rain rattled the windows of Mob's bedroom. He lay on his
side, in bed, wearing nothing but pajama pants. His soft chest was in the hands
of Mogami, each tapered end petted like a goose. Poor Shigeo was humiliated,
closing his eyes and covering his mouth to stifle the whispered moan. Mob's
body improvement training had lapsed. Before Reigen died, his chest was flat.
Now the pectorals had loosened. Due to his fluctuating hormones they developed
into delicate, volcano shaped breasts. Mob didn't like wearing a sports bra to
hide it. They were uncomfortable. He simply tried to cover his chest as much as
possible with sweaters. But now with Mogami in his life, he could not hide
anymore. The flicking of Mogami's fingers caused his body to tingle and his
heart to race. Mob's little gasps were music to his ears.
"Are you ready for me to possess you?" he said in a low purr.
"No." said Mob. His whole body gave a writhe as Mogami played with his rosy
nipples. The man's rolling fingertips teased the flesh to harden and swell. The
pink pebbles underneath the touch became more sensitive the longer the torture
went on. His chest was tingling with feeling, his spine aching.
"Oh..." Shigeo moaned softly, despising the touch.
The pounding was unbearable. At what point would he just give in?
"Such soft skin..." Mogami murmured in humored bliss. He pressed a warm kiss to
Mob's neck, just under his earlobe.
"When Shishou's killer is brought to justice, y-you have to go away." Shigeo
stammered.
"Right..." Mogami breathed right in his ear with a smirk, "Until then, you're
all mine."
"Stop it..." Mob begged. His body ached for more of Mogami, but his mind was
disgusted.
"I can't stop." said Mogami restlessly, holding Shigeo's round little stomach.
"Why can't you stop?" Mob desperately asked, huffing air through his mouth. His
arms behind him itched to control the situation, to show the spirit how he
could defend himself.
"We're partners." insisted Mogami, "Just like you are mine, I too, am yours..."
Another hot kiss was planted on Mob's neck.
"Use me." said Mogami, "We should share our pleasures, not deny them."
Mob jerked when Mogami's tented erection, which had been digging between his
legs, rode up and poked impatiently between his inner thighs and ass cheeks. It
tickled in a deep, sensual way. How he wished Reigen was scratching his itches
instead of this monster!
"I wish you were him..." whispered Mob. He groaned as a tear came out of his
shut eye.
"Oh." muttered Mogami scathingly. His hand, so large and his knuckles so white,
spread itself over the rounding slope of Mob's hip. "Can your old Shishou hold
you like this?"
Mob sniffled. "We never touched." he explained, "Shishou and I waited so that I
could grow up before we did it."
"So you've been alone all this time..." Mogami observed, "Your powers do not
respect you anymore because you let your innermost desires go to waste."
"You don't understand..." Mob whimpered. His hips did a roll - Mogami had
started to finger the crevice behind him, invading it. "Oh, no, please, Mogami-
san..."
"Don't call me Mogami-san, Shigeo. We're more than that. Just call me Keiji."
said Mogami with a smile. He relished the boy's discomfort, although he would
have also enjoyed if Shigeo just fell apart right away and let him make love
the way he wanted. The torture and the boy's resistance would only make it
easier to possess him once more.
"Shigeo..." he said huskily. His breath, hot and moist, touched Mob's tense
back. "Let me in. I promise I am much better than your master..."
His dry lips pressed up between Shigeo's shoulder blades this time, the
increased intimacy causing both of them to shiver. He held the boy's arms at
bay.
Mob was breathing heavily, turning his head to look at Mogami. "Maybe you can
have your way, but I'll never love you." he said quietly. His voice broke in a
sob and he ducked his head, tears flowing down his cheeks.
"Shh..." Mogami hushed, taking that sad face in his hand, "I don't like when
you make empty promises." he said behind Shigeo.
Mob yelped as Mogami lifted his knee over his shoulder so that he could
straddle the boy, putting him on his back. He watched Mogami's face lower over
his abdomen. The next second the spirit's tongue started licking his nipples.
As it flicked back and forth to stimulate them, he held down Shigeo's slim
wrists, ignoring the boy's moaned protests. Mob's pink nipples were delicious
to Mogami, standing up on top of his gently jiggling breasts. The boy panted,
an ordinary reaction to the building of breast arousal.
"I like the way you taste." said Mogami, speaking both of Shigeo's flesh and
his vulnerability, "But not just that."
"Why?" Mob cried, unable to look down anymore.
"They connect us." Mogami told him, "Your brain creates oxytocin when your
nipples receive stimulation, an evolutionary characteristic of social bonding.
This chemical will cause you to feel emotionally attached to me."
"No!" Mob cried, struggling to free his wrists, "Let me go! Please!"
"I won't." said Mogami cruelly, "I'm going to stop when you let me do what
Reigen could never do."
He sucked up Shigeo's left nipple, making it stand tall and red. His tongue
flicked over the tip, teasing, tickling. Mob squirmed and moaned "Oh, p-
please..."
Mogami didn't listen, of course. His lips and tongue danced with the sobbing
boy's chest, dragging long, needy moans out of him. He even nibbled a bit with
his teeth, just a bit. At this point, Shigeo's nipples were so red, stimulated
to the point of orgasm, that they tasted like iron. Shigeo was breathless. His
heart beat so fast, pounding under Mogami's mouth. His breasts shone with the
spirit's saliva. It felt so unbearably good, this stolen intimacy. He was
hanging off the edge of orgasm, sensations fluttering in his chest and seeming
to pour out of his glands into Mogami. It was such sweet torture that nothing
else in the world existed. Mob gasped for air and moaned deeply,
"Ah, Mogami-san... please~"
"So cute..." Mogami purred. Again his tongue flicked up and down over the right
nipple. It was slippery and stone-hard. He guessed the boy must be dangling
from the cusp of release, unable to reach it and almost blinded by need.
"Ahe, please~" Shigeo sobbed desperately. Mogami could hear it in his voice;
his captive was no longer begging to be freed. Mogami loosened his grip on
Mob's wrists until they were totally unhampered, and started to travel towards
Shigeo's solidified cock. As he started to pump it and rub gently on the glans,
Mob practically screamed for release. His small hands grasped the pillow and
his back arched so drastically off the futon he became like a bridge. "~Ah!"
"Eager, are we?" said the spirit, smiling.
Mob could do nothing but stare past his arching abdomen, down at the hand
pumping his cock, crying due to the burden of his body.
"You know, I care what you think of me, Shigeo." Mogami went on, listening to
the beautiful sound of Shigeo losing control of his voice, "Can you tell me
those magic words?"
"Please..." Mob begged as if he was begging for his life.
"Not that one..." said Mogami, "What can you offer me...?"
Mob answered with an agonized sob, knowing he'd been pushed unnaturally far
trying to resist Mogami's torture. "Take it!" he cried, giving himself over
finally, "It's yours!"
"Mmm..." Mogami's satisfied hum over his chest tickled. Mob gave up, eyes
falling shut in defeat. He felt like he was occupied internally by a visitor.
It was Mogami, entering him. Mob sucked in a breath. Suddenly Mogami had
control, and he was finishing off the job he'd started. Sliding Mob's swollen
cock through his fist, up and down, again and again, he drove Mob off the
brink. Mob opened his eyes as the climax crashed over his body and drew the
most desperate, throaty moan out of him. He sobbed at the ceiling, undone by
his orgasm. It was only possible because of the ghost inside him.
"Hah, h~ah..." he panted, pouring with sweat.
"How do you feel, Shigeo?" the ghost asked.
"I... feel free." Mob softly responded, "Thank you."
"My pleasure." answered Mogami.
This toy was all his to entertain himself with. Shigeo would understand his
situation soon enough. They could seek revenge for Reigen's death, but first,
he'd play a little bit more.
