Chapter 1

“You’re really going to do this?” A young woman asked. She and a slightly chubby young man were standing outside the gates of a beat up looking building. “You’ve got to be kidding me.”

“I really mean it I want to become a sumo, sis!” The young man grabbed the gate and looked into the front yard. “Dad has already paid my entrance fee”

His annoyed sister took hold of the young mans arm. “Really Okada of all the stupid things you’ve done!”

Okada snatched his hand away. “It’s not stupid Suki!”

“YES IT IS!” Suki shouted. “This is just like the time you tried out for base ball or the time you wanted to be a soccer star. Or the time-”

“This is different!” Okada lowered his head. “I tried out for those things years ago. I’ve… I want to do this”

Suki put her hands on her hips and leaned forward. “Really why?”

“For… for Mr. Yugoro.” Suki sighed she knew what her brother was referring to.
---------------------------------------------------------------------------------
Years ago when Okada was fifteen he was cruelly picked on by bullies. They would tease him because of his size and his inability at sports. Which is why he tried out for so many only to fail. During on especially bad day a pair of high school seniors who were on the baseball team had chased him for several blocks and had cornered him down an alleyway.

“Finally stopped running fat boy?” One of the boys asked. The two bullies stepped closer. “Where do you get off trying out for my team fat ass? Huh?”

“I was only trying to… to.” Okada fell to his knees. “I’m sorry I won’t bother you again just please don’t beat me up, please.”

“Look Kobo, Lardy is about to cry.” One bully teased. They both raised there fists and were about to strike when the heard a hum-humph from behind them.

The bullies turned and were greeted by the sight of a large man, a very large man whose hair was tied in a tight knot. He was clothed in a brightly colored silk kimono and wore a pair of comfortable sandals. “Excuse me boys but may I ask you what you are doing to that young man there.” He asked them

“Who are you fat boys daddy?” on of the bullies sneered.

The man chuckled. “No I am not his father but still I don’t think you should be doing, whatever it is your doing to him.” He looked past them to Okada. “He looks very frightened.”

“We’ll do whatever the hell we want to, to him.” They turned toward the man. “Who’s going to stop us? You chubby?”

The man crouched down. “If I must then yes.” The bullies smirked to each other then charged at the man. Just as they were about to make contact he stepped out of the way and they both stumbled into a nearby dumpster. Before they could recover he closed the lid.

All Okada could muster was a wow. The large man walked over to him and offered a hand. “Are you ok son?”

Okada took it. “Who… who are you?”

“Is that how you thank someone who just helped you?” The man laughed. Okada apologized. “It’s alright I’m Yugoro Nakae and it was a pleasure helping you. I’ve dealt with people like them when I was young too.”

“Your name sounds familiar.” Okada said. Then it hit him. “You’re a sumo wrestler one of the top sumo in Japan!”

“Yeah that’s me.” Yugoro laughed. “I see my reputation precedes me.”

Okada looked up at Yugoro admirably. “I saw all your matches you made Yokozuna in record time!” Yugoro gave him an embarrassed look. “Man what I would give to be just like you.”

“Just like me huh?” Asked Yugoro. “Well you could be if you entered the right heya.” Okada looked confuse. “That’s a place where they train men to become sumos. All it takes is the right stable master and then you’re set.”

“I’m not good at sports of any kind.” Okada said disappointed.

“Nonsense I was very much like you when I was you age. And…” Yugoro poked his belly. “You’re just right.”

The younger man blushed. “You really think so?” He asked

“I do!” The older man shouted. “I fact I want you to promise me that you’ll become a sumo and that one day we’ll meet in the dohyo the wrestlers ring. Got it?!”

Okada didn’t know what to say but the way the man talked and the confidants he had, had an effect on Okada. “I will Mr. Yugoro, I will!”
---------------------------------------------------------------------------------

That was three years ago, ever since then Okada watched bouts, read books and ate slept and breathed anything sumo. His bedroom had become a shrine and after months of waiting he received a response from a local stable saying that he may try-out for a position at the heya.

Suki gave her brother a pitiful look. She felt as if this was another one of his harebrained schemes. “Fine… go ahead and do this silly thing. But don’t come crying to me when it turns ugly.” Suki walked over to her car and took out a suitcase. She handed it to okada.

“It’s not silly neechan.” Okada stated as he took the suitcase. “It’s something I want to do.” Suki hugged him then got into the car. She gave him one last look then sped off.

Okada turned around facing the heya. “Look out world of sumo! I’m com-”

“How cornball can you get.” Said a voice from behind him. A young man walked up next to okada. He was wearing a black jumpsuit. “I take it your going here to?” Okada nodded. “I’m Watanaba Hideyuki nice to meet you.” He offered his hand.

Okada took it. “I’m Okada Hiroaki nice to meet you.”

“So Okada are you also here to learn sumo?”

Okada nodded. “Yeah it’s always been a dream of mine.”

Watanaba grimaced. “Humph, not me my parents are forcing me to come here. I don’t give a dam about this stuff.” Okada gave him a sour look. “Whatever we should be getting in, we were suppose to inside by now.”

Okada and Watanaba forced open the gates and walked up to the front door. ‘Here it is! My first step to becoming Yokozuna.’ Okada thought as he reached for the doorbell. He rang it and the sounds of footsteps could be heard from the other side.

The door swung open and a man poked his head out. “What do you want!” He rudely growled. Okada froze and Watanaba held up his fists. The man blinked “Oh it’s you two, Your late!” He opened the door and the two boys walked in.

The man who let them in was obviously a sumo wrestler. He was larger then the two boys and older. He wore a kimono like Mr. Yugoro wore but it seemed less expensive. “Show me your papers.” Both younger men looked at each other. “Your acceptance letters!”

The Okada scrambled through his suitcase and pulled out the paper. Watanaba took his crumpled letter out of his coat pocket. The man looked over the pieces of paper. “Well it all seems to be in order.” He smiled up at them. “But your still late so that means you get bathroom duty on your first day. The boys will be happy about that”

“You mean we gotta clean the bathroom tomorrow?” Watanaba complained.

“Tomorrow?” The man laughed. “You start working today! As soon as you get settled in of course. BOYS!!!”

What sounded like a herd of cattle stampeding could be heard upstairs of the house then to the stairs that led to the room they were in. from the stairway four young men appeared in t-shirts and boxers. “Line up.” The man yelled. The younger boys got into formation.

“Yes sir, Kunio-sensei! The all yelled.

“Okada, Watanaba. These are the other trainees here from right to left. It’s…” he pointed to the first boy he looked around Okada’s age and was as big. But had a shaved head. He had a slightly clueless look on his face. “That’s Kamata”

Next was the second boy, largest of the four. His eyes seemed to be squinting and had a buzz cut. “He’s Nishiyama, but we call him Nishi”

The third was the tallest but also had the least amount of fat. He had a serious look on his face and thick eyebrows that made him look as if he was mad. “The quite guy is Kenchi”

The last boy had a sneaky look on his face. He also seemed a little weird his boxers unlike the others which were plain were red with pink little hearts on them “And lastly, this hear is Kondo.

Boys this here is Okada and Watanaba, Our new trainees” The group looked over at the two new arrivals. ‘Why would sensei allow such gutter trash into our home?’ Kondo whispered to his friends.

Kunio sighed. “Knock it off Kondo, you said the same thing the first time you met the others and now you four are inseparable.” Kondo humped. “That’s it pal I want to have a talk with you in my room!! As for you two, Kenchi!, show them to the empty room.”

“We have to share a room?” Asked Okada. Kunio nodded. “Everyone in the Heya has to.” He smiled. “Unless you’re promoted then you can have your own.”

Kenchi pointed upstairs then motioned for the two boys to follow him. Okada reached for his suitcase. But it was snatched by Kamata and Nishiyama.

The sensei laughed. “You won’t be needing those things!” Kamata handed him the bag. “Here in the stable lowly trainees only get the bare essentials.”

The three other boys laughed as Okada, Watanaba, and Kenchi ascended the stairs.

“So what’s with that Kunio guy?” Watanaba asked when the three of them got out of earshot. Kenchi growled. “Fine don’t answer me.”

“I think what Kenchi-Senpai is trying to say is don’t talk bout the coach like that!” Okada said to Watanaba.


Kenchi gave Okada a small smile as he stopped at the end of the hallway, he pointed to an open door. The two boys walked up to it and peeked inside, it was a modest room with little on the walls. In the center were two futons one for each of them.

“We’re suppose to live in this dump?” Watanaba snapped. Kenchi roughly handed him a small package. Then politely gave one to Okada. They had “Put these on imminently” written on them.

“Thank you… but what are these?” Okada asked.

Watanaba had already opened his. And took out the contents a long piece of cloth. “What the hell is this??”

Kenchi grunted then hooked his thumbs in his boxers and swiftly pulled down. Both boys quickly turned away but feeling him staring at them turned back. Kenchi stood there with a smirk on his face his hands on his hips. And wearing a cloth strip as pants.

“Ohhh! A sumo diaper.” Watanaba sighed. “but yours and ours are black? I thought these were suppose to be white.” Kenchi gave him a dirty look.

“It’s called a Mawashi.” Okada corrected. “The traditional grab of the sumo and the reason it’s black is because beginners like us can only wear black.”

Watanaba pushed past okada. “Thank you Mr. Brownnoser now if you don’t mind I’m going to put this stupid thing on.”

Okada chased after him. “Wait where are you going?”

“I prefer to change clothing alone.” the rude young man answered.

Okada turned to Kenchi. “Man that guy is rude.” Kenchi nodded. Without thinking okada pulled down his pants and underwear. He heard a low whistle. He raised his head to see Kenchi leaned against the doorway watching him. “Um… um… excuse me sempai.”

Kenchi raised an eyebrow and getting the hint left the shy okada alone the dress.

Meanwhile down the hall in the restroom Watanaba had finished putting on his Mawashi and was looking at himself in the mirror. “I look stupid in this.” He remarked. “I don’t see why dad is forcing me to do this crap I mean really this lifestyle sucks. I couldn’t even bring my stuff from home… wait!” Watanaba walked over to where his discarded jacket laid and reached into the pocket. He pulled out a small digital camera. “I almost forgot about this, but I better be careful if that loud guy finds this he’ll take it away.”

“But head coach!” Came Kondo‘s voice from the other side of the bathroom door.

“No I’ve heard enough!” Kunio yelled. “It’s there first day here be nice. Or at least pretend to be!”

Watanaba opened the door a little. Kunio and Kondo stood there face to face. Kondo smiled at his coach. “Alright sensei I’ll try.” He lowered his head as sign of respect. But from Watanaba’s view he could see a sly grin on the mans face.

“That’s a boy.” Kunio said. Then unexpectedly he put his hand under the younger mans chin and made Kondo look him in the eyes. Then with the other one grabbed his groin. “Now since you promised to be good I’ll give you a little action.” Kunio pulled him further down the hallway out of Watanaba’s sight.

Watanaba laughed. “Well, well, well. I’m pretty sure that having sex with a trainee is against the rules.” He stepped outside the bathroom just in time to see Kunio and Kondo walk into a room at the end of the hall. “Yup illegal.” He snapped a picture with his camera and tiptoed toward the door. He waited a few minutes then approached the door

“Ohh coach!” Kondo moaned through the door. Watanaba opened the door a little and to his amazement. There the two were in the middle of the act. Kondo was on all fours his strange boxers around his ankles. With coach Kunio thrusting into his willing ass. “Coach!, Coach!, Coach!, Coach!, Coach!, Coach!”

Watanaba was a bit Kamatan back by the display but after the shock wore off. He pulled out his camera and began snapping pictures. “This is the perfect kind of blackmail!” He whispered.
---------------------------------------------------------------------------------
Okada’s and Watanaba first day was a tiring one. First they had to endure tough training, which was hard even for heya standards.

When they asked the coach he responded by making it even harder. After the workout they as well as the other boys were forced to clean the house. Okada and Watanaba were given the hardest chores. Cleaning the four bathrooms and bathhouse.

After the cleaning marathon they brought Kunio his lunch and had to stand there while he ate incase he wanted anything. For the two boys who had not eaten yet and were hungry it was excruciation.

But after he finished they were allowed to eat. But after they saw what they were eating the regretted it. It was a thick stew that smelled horrible and had brown and green chunks floating in it.

After forcing the concoction down there throats they had were told to nap for a few hours. As soon as they woke up they had more chores to do which lasted until nightfall.

After the day they had both boys fell into there beds. “I HATE THIS SHIT!” Watanaba yelled.

“I admit it’s tough but I actually like it!” Okada said cheerfully. Watanaba threw his pillow at him. “Hey!”

“Dam do you ever turn off?” He asked. Okada shook his head no. Making the other boy actually laugh. “Your so naive.”

“I’m not naïve.” He protested. “I just like this life style. Except for the fact other people are cleaning my room.”

“Well I don’t like it.” Watanaba complained. “First there are these stupid diapers, second there’s… wait what did you say about our room?”

“About the cleaning?” Okada asked. Watanaba nodded. “Kamata and Nishiyama cleaned it today.”

Watanaba panicked and raced over to there closet where his camera was but before he could Kamata opened their bedroom door. “Kondo wants to see you Watanaba.”

Watanaba got a nervous look on his face. “Why?”

Kamata walked up to Watanaba and grabbed him by his shirt. “Just come!” he shouted.

Okada stepped between them. “Why should he have to go with you it’s late.”

“Because Kondo wants him to, and since Kondo is not only your sempai but the top trainee here you’ve got to do what he says!“ Kamata grabbed The shocked young man by the arm and dragged him away leaving Okada wondering what was going on.
---------------------------------------------------------------------------------

“Look here Kondo!” Watanaba yelled. “Back off or you’ll be sorry!” Watanaba had been brought to Kondo’s large room. It was painted the same colors as his boxers from before Pink with small red hearts and had several piles of stuffed animals all over the place.

“So how was your first day in our humble Heya…? Watanaba was it?” Kondo asked ignoring his threat.

Watanaba stood there angry with his head turned toward the ceiling. Mainly because he knew this was not good. Secondly because the other for boy the seniors were half naked only wearing shirts. Kondo sat on a small stool with the others standing around him.

Watanaba decided to play along. “It was fine, I especially enjoyed the shitty chores you all gave me!”

“I could tell by the smirk on your face.” The other three boys laughed at Kondo’s joke. “But that is not the reason you’re here now. I want to know what you’ve seen today”

“I saw nothing fatso! Watanaba snapped.

“My, my what a fibber” Kondo yelled. He threw a bunch of papers at him. They were printouts of the pictures that Watanaba took earlier of Kondo and the coach having sex.

Watanaba picked up the photos. “Where is my camera!? How did you even know where to look!?”

The group burst into laughter. “You idiot I know everything that goes on in this house.” Kondo announced. “And besides when our darling coach and I were fucking we could see your reflection in the mirror.”

Watanaba looked at them in surprise. “You… you saw me watching?

Kondo gave him a sly look. “Dam strait! Me and coach planned the whole thing to see if you boys liked the boys scene?” Kondo let out a loud laugh. The as suddenly as it started he buried his head in Nishiyama’s belly. Making Watanaba comically fall over. “Boys, can you believe this whelp? He took pictures of me and coach trying to have him booted from the league.” He pretended to cry.

Kamata and Kenchi quickly got behind Watanaba and forcibly held him. He struggled to get free but to no avail. “Let me go!” He shouted.

“Shut buddy!” Kamata yelled back. “We’re going to make you sorry for what you were going to do.”

“I SAID LET ME GO!” Watanaba continued. “OR ELSE I’M GOING TO KICK ALL YOUR ASSES! LET ME GOOOOO!” He sneered at Kondo. “YOU… YOU FATASS TELL YOU GOONS TO LET ME GO NOW OR I’LL-”

Kondo was taken back by this rant. “Man you sure are a meanie.” He laughed. “Maybe this will make you calm.” He took out a spray can and sprayed its contents into Watanaba’s face.

Watanaba felt the world around him swirl his vision got blurry. “Sleepy dear?” Kondo quipped. “Well boys how about we teach this inbred a lesson huh?”

Kenchi grunted confusedly. “Kenichi want‘s to know what you mean Senpai?” Kamata responded.

Kondo stepped forward and began to suck on Watanaba’s skin. “Knock it off asshole.” Watanaba said weakly. Kondo ignored this insults and began rubbing his captives chest.

“Asshole huh?” Kondo chuckled. "Well we’ll get to that in a bit.” His hand slid down Watanaba’s belly and into the hapless mans underwear. He cupped his balls and dick and gave them a rough squeeze. Inciting a groan from Watanaba. “Well, well looks like he’s enjoying this treatment.” Kondo nipped at his cheeks. “Boys why don’t you join in and give him a proper welcome to the heya.”

Nishi was the first to respond and kissed his way down Watanaba’s back. When he got to the young mans crack he slowly pulled down his underwear.

Watanaba yelped when he felt Kondo pinched his nipples hard. Kamata and Kenchi who were still holding him began to nibble on his sides. Lightly sucking and biting him.

“No stop.” Watanaba said again. “I’m not gay stop it.” Kondo got down onto his knees.

“Really now huh?” He laughed. “Then why are you here? Our coach only picks an individual who enjoys the pleasures of the male gender.” Kondo took Watanaba’s hardened dick into his mouth and began to suck. Watanaba felling this sensation nearly cummed then and there but decided not to give them the pleasure.

But that was hard the four boys were doing their best utmost to make him cum and he knew it and hated the fact that no matter what he did they would eventually win out.

Then suddenly they stopped and threw him on the floor. Watanaba wanted to get up but couldn’t he watched as the four of them all smiling took off their shirts

“Woo-hoo! Let’s get this fuck show started!” Kamata said excited

“Indeed let’s get this thing begun.” Kondo wetted his fingers with his mouth and kneeled between Watanaba’s legs. “Time to lose that debu cherry of yours.” He thrust two of his fingers into Watanaba’s anus making the younger man scream out loud. This did not deter Kondo ministrations he finger fucked him slowly. “You enjoy this don’t you?” Watanaba shook his head no. “Don’t you!?” Another no. “Don’t you!!?” Watanaba yelled and with a mighty burst came over his stomach and chest. See you loved it. No that you got off you need to return the favor. Kondo shook his dick and smiled at him. Then grabbed the young mans legs and held them at his sides. With one well placed thrust he pushed past Watanaba’s ring and entered him.

Watanaba feeling him intrude yelled in pain. But his mouth was stuffed with Kamata’s balls. He had positioned himself over Watanaba’s head and when he opened his mouth he kneeled down. Nishi also took the opportunity to lay his head on their victim’s stomach and lapped at Watanaba’s penis while Kenchi Plowed his ass.

Kondo growled. “AHHH! You guys are going to love this kids ass. He’s squeezing heck out of my dick.”

“Ha-ha.” Kamata laughed. “Look at this guy he’s loving this stuff.”

“Keep going boys we’ve go all night!“ Their leader added. The foursome continued there exploits not noticing that the door leading to the hall way was opened just a crack or that a shadow could be seen in the darkness. Okada was on his knees looking into the room his pants down and stroking his dick feverishly.
---------------------------------------------------------------------------------

Later that night after Okada had finished his masturbating. Watanaba came back to their room. His hair was messed up and he was covered in sweat. “Watanaba what happened?” Okada asked. He knew of course but knew he couldn’t tell him.

Watanaba glared at him. “Nothing they just wanted to talk.” He got into bed and turned away from him.

Okada decided not to bother him and turned out the lights. “Good night.”

Watanaba grunted a response. He laid there for a few minutes replaying the events in his head. He was pissed at the seniors but at the same time he blushed and his dick turned hard. He was angry about what happened but he was more angry that a small part of himself wanted to have sex with them again.
