     Sometimes the best feelings can come from a brother.
Notes
See the end of the work for notes
As the front door opened, two boys walked through, their backpacks flung to the
ground along with their shoes. Shigeo, the older brother, went up to his room
right away, but Ritsu stayed downstairs. He crossed the room to the kitchen,
opened the metal fridge and skimmed it’s contents before grabbing a bowl of
strawberries. After shutting the door, he turned back to the room and sighed.
There was nothing ever to do at home. His mother and father were out the entire
day and he wasn’t allowed to go anywhere without Shigeo with him.
He took a bite of strawberry and juicy yumminess exploded in his mouth. At
least the food was good.
“Ayy! Nii-san! The strawberries are ripe if you want some!” Ritus shouted up
the stairs that led to the boy’s rooms.
“I will be down soon!” Shigeo’s voice travelled down to the younger boy. Ritsu
finished his strawberry, and turned to throw away the leaves. He grabbed a lone
cup was on the counter and filled it up at the sink. As he turned to go back to
the strawberry, his body bumped into an object, spilling all his water. His
eyes looked up and he realized that he had bumped into Shigeo, who was now
soaking wet. His waist and below were soaked with his water.
“Ah! I am so sorry Nii-san!,” said Ritsu as he scrambled to get a towel from
the counter. He snatched it and started wiping all the water off of Shigeo.
When his mind caught up with what was happening, he realized he was wiping
Shigeo’s crotch with the towel. He looked up at his older brother, afraid of
how he might react. Shigeo’s face was red but still stoic as ever as he looked
down in curiosity at his little brother.
“Ah, Ritsu… I can do that myself.” Shigeo offered, holding a hand out for the
towel.
Ritsu took a moment, staring at his brother, his face flushed with
embarrassment before he finally moved. “Yes! Right, here.” He slowly handed the
towel to his brother and stood up from the floor. As his older brother wiped
himself down as best he could, Ritsu grabbed another towel and started cleaning
up the water that had spilled onto the floor.
As he dabbed at the water, Ritsu reached up to his face, feeling his burning
cheeks. ‘Why did I act so weird?’ He thought to himself. Behind him, Shigeo was
watching with an odd look.
The next day, Shigeo had returned home late to his brother's curiosity. He
tiredly explained that the body improvement class literally ran late, and then
dragged himself into the kitchen to grab a small carton of milk. After taking a
few large gulps, he finished off the carton, and left the room.
Shigeo then walked into the living room where Ritsu was. He lets his body
collapse onto the couch, but then noticed his younger brother messing with
something on the coffee table. Much to Shigeo's dismay, Ritsu was perusing
pictures of his crush, Tsubomi, that he took from Shigeo's room.
Being the little brother he is, Ritsu bolted across the living room with
pictures in hand as soon as he saw Shigeo get up to take his pictures back.
Shigeo ran after him in hot pursuit, and they both sprinted up the stairs.
Suddenly, Shigeo’s poor stamina kicks in and he trips on a stair. His arms
reach out in desperation for anything to grasp on to to keep himself upright,
but his hand ends up grabbing the back of Ritsu’s pants. Ritsu’s pants and
underwear are both pulled down as Shigeo lands on his stomach on the stairs.
Feeling the bunched cloth in his fist, Shigeo glanced up only to see the soft,
slightly pink and plump form of Ritsu’s exposed butt above his head.
Embarrassed, Ritsu tried to cover himself, but it wasn't like they haven't seen
each other before. They have taken baths together after all.
Shigeo's cheeks turned a crimson hue when he noticed just how different Ritsu's
body had changed since those times. Tufts of wiry, black pubic hair adorned the
base of his cock.
He'd be lying if he said he wasn't a little turned on by his younger brother's
exposed form and shy demeanor.
Shigeo may only have one year more experience with the trials of puberty but a
perverted thought popped into his head. “Maybe I should teach him a thing or
two.”
All of this happened in an instant, Ritsu was still a flustered mess on the
step, trying to cover his shame and embarrassment.
“Sorry,” Shigeo apologized as he pushed himself up from the step. Ritsu, who
was red in the face pulled his pants and underwear up quickly. Shigeo’s form
moved so he was over Ritsu and the younger felt his breath hitch as he stared
at his older brother.
“You look fine,” Shigeo added, and trailed his hand along the boy’s left
shoulder, feeling the dips on bone and muscle. His hand traveled to the naked
collarbone and dragged his fingers along to the bone until he reached the dip
in his neck. Shigeo moved his face away from Ritsu’s and brought it down to his
neck, placing his lips on it.
“Ngh Nii-san,” Ritsu gasped at the soft lips that touched him. It was weird,
this was his brother, but it felt right and it felt good. He closed his eyes
and paid attention to his brother who was lightly kissing his neck. His smooth
lips continued to graze over Ritsu’s skin occasionally pressing down.
Shigeo shifted his body, moving his right leg in between Ritsu’s legs. He
slowly rubbed his knee into the other boy’s crotch. Ritsu gasped at the
friction, it felt amazing. He rubbed back into the knee giving him pleasure.
Shigeo moved his lips to the boy’s jawline, he slid his tongue along it and he
brought his lips up to Ritsu’s lips.
Ritsu’s whose eyes were shut wasn’t ready for the kiss but he parted his lips
and let his brother kiss him. Shigeo slid his tongue onto the boy’s mouth
grazing along teeth until to Ritsu’s tongue they met.
Ritsu tried to hard to match the passion Shigeo was putting into the kiss but
this being his first time he ended up just letting Shigeo take control. After
all Shigeo is his big brother, he should know more about these kinds of things.
Shigeo, in fact, had no idea what he was doing. “Ah, are our lips supposed to
be like this? Can I put my hand here? Ritsu seems good at this…” Thoughts like
these swirled through his head but the thoughts of pleasure outweighed them.
Suddenly Shigeo remembers the reason why there in this hot situation. He
snatches the photo from his very distracted brother and rushes up the rest of
the stairs and into his room. Ritsu still stunned on the stairs, his hormones
begin to take over, he needs his brother's sinful touch.
After hiding the picture in new spot Shigeo turns and goes back down the stairs
to see his brother kneading his erection through his pants. “Nii-saaan please
touch me again.” Ritsu calls out, in a needy whine.
A blush spread through Shigeo’s cheeks. He slowly descended the stairs. He
reached his hand out, Ritsu reached for it.
“Let's go to my room,” said Shigeo. Ritsu took the other’s hand and they both
went into Shigeo’s room.
As the got into the room, Ritsu waved his hand in the air toward the door and
it shut. Shigeo got closer to Ritsu, wrapping his hands around the boy’s hips.
He slipped his hands under the waistband of Ritsu’s pants. He pushed the pants
down revealing white tight underwear. Shigeo trailed his hand to the bulge and
ran his fingers up it. Ritsu whimpered at the touch. He rested his head by
Shigeo’s neck. He put his lips against the bare skin and kissed lightly.
Goosebumps washed over Shigeo’s skin, his heart beating like a drum his soft
flesh turning a light pink. The rhythm of the drum beat marching his heart
straight to hell. He knows it is wrong so very wrong but he lets his
inhibitions go.
Shigeo started to rub the clothed member. The sudden pleasure made Ritsu
whimper, and Shigeo looked up before applying more pressure to it. Shigeo
reached into his brother’s underwear and pulled out his stiff cock, looking
over it in fascination. He slowly moved his head closer until his warm breath
blew over it, making Ritsu shudder in pleasure. Ritsu jolted when he felt his
brother’s warm, wet tongue lightly run along the shaft to the tip.
Shigeo gave the dick in front of him several more pumps with his hand, watching
Ritsu’s face contort in pleasure. As he pumped Ritsu’s cock, he felt himself
getting hard and reached his hand down between his own legs to feel himself.
Soon, Ritsu saw this and reached out so they could jack each other off
together. Shigeo rutted up into the grip around his cock before remembering
something. Gently, he moved his brother’s hand away to stand up.
“Wait right here, Ritsu.” He said before walking to his room and coming back
with two medium sized dildos.
“N-nii san… Where did you get those?” Ritsu asked, confused.
Shigeo stood silent for a moment, thinking back to the adult shop Reigen had
dragged him to for an exorcism, and how he had not-so-discreetly stopped to
stare at the display when the job was over. He had been surprised when Reigen
had slipped him a few extra dollars as his pay that day. In response to Ritsu’s
question, Shigeo shrugged and sat down in front of him.
“Do you want to use them?” He asked shyly, and Ritsu gave a slow nod in
response.
Shigeo sat in between Ritsu’s legs and stuck his fingers into his mouth before
moving them to his brother’s puckered hole. He heard a gasp as he entered, but
at Ritsu’s urge to continue, pushed in further. Scissoring, and curling his
fingers, Shigeo stretched Ritsu so he’d be ready for when the toy went in.
After pulling his fingers away, he spat into his hand then spread it onto the
thick rubber shaft of one of the toys. When he believed it was lubed enough, he
spread Ritsu’s legs further and rested the head of the fake cock so it was
barely pushing at Ritsu’s entrance.
Shigeo breathed out and continued to push the dildo into his brother. His mouth
watered at the sight of Ritsu panting and moaning. The dildo was all the way in
when Ritsu said “Stop, keep it there”.
Shigeo nodded and went to town on his hole. He took two of his fingers and
swirled them around in his mouth. He pulled the saliva coated digits out of his
mouth and brought them down to his own hole. At this point Ritsu’s breathing
was down a bit and he seemed a bit calmer.
Shigeo pushed the two fingers into himself and moved them around, trying to
stretch himself as fast as possible without tearing himself. He added a third
finger and after a minute he felt stretched enough to fit the dildo in himself.
Once he felt fit he slowly started to move the dildo in and out of Ritsu. The
younger brother cried out from the pleasure.
“If only I had more hands.” Shigeo thought, then he remembered. Using his
powers, he made the other dildo levitate into the air. Usually he needed line
of sight for telekinesis but this time he'll use his other senses. The dildo
trailed down his spine sending shivers through him guiding it down his
backside, in-between his cheeks.
All the while trying focusing on to keep his attention on his unraveling
brother, a strenuous mental task indeed. As one of Shigeo’s hands continues to
push and pull the toy in and out of Ritsu, the other has slowly moved to
gripping Ritsu’s member. With no sign of protest from him Shigeo begin to
stroke in rhythm with the dildo.
Ritsu's forearm lays across his face as the other is sprawled out, his hand
clenching the bed sheets trying to contain himself. Various noises came muffled
from his mouth he was unable to contain himself.
Shigeo's erection is standing straight up and slowly dripping with need, the
dildo he's been psychically thrusting inside of himself has been repeatedly
hitting his prostate ever since he found it.
Ritsu’s moans were loud even through his muffled mouth and his face was
extremely red. Shigeo moved closer to his brother, took his hand off the dildo
in Ritsu’s ass and it moved on it’s own. Shigeo continued to pump his brother’s
cock and leaned down to replace his hand with his mouth. He brought his mouth
all the way down and suddenly cum shot into his mouth.
Ritsu thrusted into Shigeo’s mouth a few more times. The elder swallowed the
semen that was in his mouth, it was salty but not bad. Shigeo removed his mouth
and slowly slid the dildo out of his brothers ass and set it down. Ritsu moaned
as it was taken out.
Shigeo went back to focus on himself, he took his hand and wrapped it around
his member and started to stroke, he focused hard and he psychically was able
to make his own dildo move inside him. He moaned loudly at the pleasure he was
given. His cock was red and ready to cum at any second.
“Lemme try,” Ritsu said. Shigeo looked up to see Ritsu between his legs, his
mouth was open. Shigeo got the idea and removed his hands from his member and
let Ritsu put his mouth around the tip. The dildo was hitting the right spot
over and over again, and with Ritsu sucking himself off he knew he wouldn’t
last long.
Ritsu mover his tongue around the tip of Shigeo’s cock earning another moan.
Ritsu did it again but also tried to get lower on the cock. Suddenly cum shot
into Ritsu’s mouth causing Ritsu to start coughing up the semen that shot into
the back of his throat.
Shigeo continued to thrust into nothingness as he slowed the dildo down and his
breathing slowed down. Ritsu shifted up the bed and collapsed next to Shigeo.
The older turned his head and planted a kiss on the other’s forehead. As they
both drifted off to sleep, things moved: dildos were hidden, semen was
vanishing, clothes were put onto the boys, almost as if the world wanted them
to seem as two brothers who fell asleep next to each other.
