Summary
     "Now...there is someone else that has not been mentioned. While he
     isn’t on the swim team, he is helpful in other ways. By giving luck
     and giving people “release.” His name is...Rin.
     This is no meer guy. For a guy, he has all the right curves. Deep
     cleavage and perfect ass that was huge, as were his thighs. He had
     fair skin and was beautiful in every way. His red hair and red eyes
     made his shark teeth much more exciting, but that didn’t scare
     everyone off.
     Now you must be wondering what Rin could do to bring good luck. It is
     a simple and easy answer that all three parties agree to in a binding
     agreement. That answer was only one word and three letters.

***** Prologue *****
Anyone can have a ritual. Some of these are used as you could say to get good
luck. People who think it will make them lucky will do whatever the ritual is,
and bathe in their fortune.
However, some rituals are not that old. Some are actually quite new and
exclusive to only eight boys. All who were swimmers. They are from the Iwatobi
and Samezuka swim teams.
On the Iwatobi side, you have these four boys. Haruka Nanase, Makoto Tachibana,
Nagisa Hazuki, and finally but definitely not least Rei Ryugazaki.
Continuing, the Samezuka swim team also has a few hunks. The brothers Seijuro
and Momotarou Mikoshiba, Aiichiro Nitori, finally Sousuke Yamazaki. All were
quite toned yet had something that made them unique.
Sousuke and Haru were the boys with a scowl on their face. They both had raven
hair and blue eyes. Haru’s were brighter as Sousuke’s were more teal. Sousuke
still was more bulkier and taller than Haru, but that doesn’t mean they both
don’t have…”technique.”
Mako and Ai don’t look anything like each other, however they share a similar
personality. Both are sweet and caring for others. Now there appearances are
quite the opposite. Ai is short and skinny-ish, of course meaning Makoto was
y’all and bulky. Mako is a brunette with green eyes, but Aiichiro has grey hair
with bright blue eyes. Ai also has mole on his face that makes him a little
more unique. Discarding the grey hair at least…
The last group would have to consist of Momo, Sei, and Nagisa. Sei and Momo
being brothers have similar features. Both have golden eyes and red/orange-ish
hair. Sei has more red while Momo is more orange. Seijuro is also much bulkier
and taller than both boys. However, Nagisa is way different in looks, but makes
up with the personality. He has blonde hair with pink eyes and you could
describe him as a shota. All three boys share the loud mouthed, outgoing,
hungry, and no shame whatsoever traits.
Once again, lastly is Rei. He believes in things being beautiful and perfect.
Things of opposite do not really interest him.  His purple eyes go well with
his blue hair and red rimmed glasses. Truly amazing. The perfectness also was
incredibly smart and always looked at facts. But that doesn’t mean he wasn’t
fun.
Now...there is someone else that has not been mentioned. While he isn’t on the
swim team, he is helpful in other ways. By giving luck and giving people
“release.” His name is... Rin .
This is no meer guy. For a guy, he has all the right curves. Deep cleavage and
perfect ass that was huge, as were his thighs. He had fair skin and was
beautiful in every way. His red hair and red eyes made his shark teeth much
more exciting, but that didn’t scare everyone off.
Now you must be wondering what Rin could do to bring good luck. It is a simple
and easy answer that all three parties agree to in a binding agreement. That
answer was only one word and three letters.
Sex.
 
***** A Typical Day *****
Chapter Summary
     The boys just have a typical day, but it doesn't seem that way.
     Nagisa gets in trouble and Makoto is told to stay after practice. For
     what? It seems good since Rin got him hard before telling him...
It’s a typical day for the two swim teams. All eight members arrive on time to
start the practice. But first, they have to go in the locker rooms, which is
also Rin’s room. His bed was the first thing to see when the door was opened.
It was a bohemian style bed with the curtains closed (as of right now), red
satin sheets and matching pillows. Although it was placed at the back of the
room, it was sorta in the middle as the room wasn’t too big. This gave Rin the
advantage as when the boys changed they usually faced him, and Rin could see
everything. It also helped when it was time to give them luck or release, they
could just sit and face the bed.
The eight boys chatted, some louder than others, but as they reached the locker
room doors, everyone hushed. Slowly Sousuke opened the door to see whether the
curtains were open or not. If they were open, then Rin was awake so the boys
could chat away and be loud. The curtains being closed meant Rin was asleep or
didn’t feel well, which meant be quiet. Consequences would happen if you broke
that rule.
Punishments actually happened all the time, but they were private. Rin
respected that but that doesn’t mean you wouldn’t be scolded in front of
everyone else. However, if a rule was broken with someone else you would both
be punished together.
So as to avoid punishment, Sousuke dimmed the lights before turning them on. He
then looked at Rin’s bed to see the curtains closed. A frown showed on his face
and he turned around to the rest to mouth quiet.
Calmly and quietly the all eight of the boys walked in to change. Momo and
Nagisa were quickly shushed a few times as they would start to fool around.
They would quit their actions and later resume it. After changing all excited
and were loud once more.
===============================================================================
 
“Nagisa don’t run around the pool! It’s dangerous!” An annoyed voice came from
Rei as he walked behind Nagisa safely. For most of practice, this was what
Nagisa had done. All around the pool was wet with water and a few times Nagisa
had actually slipped, but of course, it didn’t stop him. Rei was trying to stop
him before someone else said something. Not really just anyone, but Sousuke or
Seijuro.
You could describe them as Rin’s right-hand men who reported things and would
do things for him. Sometimes they would stay after practice to stay with Rin,
but no one knew why. One time Haru had actually gotten angry and said Rin was
just choosing favorites. Of course, he immediately put his head down in shame
for being so rude to Rin, but, Rin told him he wouldn’t get punished and calmly
explained that at one point they would all be treated like Seijuro and Sousuke.
Rei was trying to help Nagisa as soon as he noticed both boys were paying
attention to Nagisa. Who was still fooling around the poolside.
Nagisa laughed as he once more jumped before turning around. He was smiling
brightly and Rei could tell he was about to say something, but suddenly
Nagisa’s face dropped. His eyes were looking behind Rei so naturally, he turned
around.
Behind Rei was a maroon hair colored boy who has had his arms crossed and
didn’t look happy. He was dressed in a black silk robe that barely reached his
thighs, which meant if someone got him to bend over they could all see what was
underneath...
“Nagisa, what do you think you’re doing?” Rin said as he started walking
towards Nagisa. Haru and Sousuke, who were the closest, watched from inside the
pool as Rin marched forward. When Rin reached Nagisa, he grabbed his face and
put him between his breasts. “You know it’s dangerous and I’ve warned you too
many times.” Rin pulled Nagisa’s face back and leaned forward to whisper in
Nagisa’s ear, “Stay after practice for your punishment.” After finishing his
sentence Rin caught Nagisa’s earlobe in between his teeth and pulled it towards
him before letting it go.
“Y-Yes Rin. I’m sorry,” Nagisa said as he was let go of. He then put his head
down and walked to the starting block to practice.
Rin watched Nagisa go to make sure he would practice properly. Once Nagisa
dived in the sharp tooth male turned around and walked towards Rei who was
still in the same spot. He stood upright when he noticed Rin and started
speaking nonsense. He went on about how he was sorry and just was trying to
save Nagisa from trouble, but he was silenced with a kiss on the cheek.
Rin giggled and sweetly said, “I get it, so don’t freak out. Now go practice.”
Rei nodded and headed over to Nagisa to work on their exchange. Rin then headed
towards a pool deck chair that had a red cushion on it. He sat down and lifted
his hand to signal Sei and Sou over.
Immediately Sou got out of the pool, while Sei stopped talking with his brother
and Makoto. Both walked towards Rin who got up to take off his robe, and it
showed him wearing only a white bikini bottom. Which if it got wet, it would be
see through. He threw the robe over the back of the chair, and this time laid
down on the chair. Upon reaching Rin, both boys males went on either side of
him to wait for what he had to say.
“Is something wrong?” Sousuke asked when Rin kept quiet.
“No, I just think someone might be joining you two soon.” Rin’s voiced came out
lustful, and was biting his finger as he squeezed his legs together. They
followed Rin’s gaze which landed on Makoto who was talking with Momo. “Bring
him over here, Seijuro.” Seijuro nodded and did as he was told.
As Sousuke was watching Seijuro, he felt his hand being pulled down. He allowed
it and felt soft material under his fingers. His hand was then tugged hard
which caused him to press down roughly into Rin’s crotch. A slutty moan was
heard by only him as it was quiet. Sousuke knew what to do, so he started
squeezing Rin’s balls and rubbing the member hidden underneath. Rin’s hands
were moving their way up and down Sousuke’s arm as he couldn’t keep them in one
place. This wasn’t just fun for Rin, it was for Sousuke too which was
noticeable by the growing bulge in his legskins. Unfortunately, almost as
quickly as it started, it had to end as Seijuro returned with Makoto. Sousuke
took away his hand and stepped back for Makoto to take his spot.
Makoto was nervous as he thought he was somehow in trouble. “Umm...You called
me?” He said in a shaky voice.
“Mmmm, yes I did,” Rin gasped out as he was still very horny. “Just stand
still, and don’t touch.” That was what all he said as he reached forward and
placed his hands under Makoto’s sack through the swimsuit.
Rin’s hand gave a tight squeeze before massaging them. He repeated the action a
few times until he noticed Makoto’s swimsuit started to stretch. Then he pulled
the swimsuit down just enough so the cock could spring free. Makoto was shaking
and red in the face as he was powerless in this situation. He was also
embarrassed as he was exposed while no one else was. Yes, Sousuke was hard, but
he wasn’t getting touched and he dare not to touch himself without Rin’s
permission.
The shaft in front of Rin was leaking precum but that wasn’t what he wanted to
see. Once Rin got a full view of Makoto, he looked up at him and smiled. “Stay
after practice with Seijuro and Sousuke. After you change just stand outside
while I give Nagisa his punishment. Then I’ll explain what’s going to happen to
you.” Rin said as he looked into Makoto’s jade eyes, and giggled at his tomato
face. Rin looked back down and kissed the tip of Makoto’s cock, which caused
some precum to smear on his lips. He licked it up and swallowed the juice he
loved so much.
“Now, you and Sousuke go and take care of your problems. Then get back to
work.” That was the reply they got to their pleading eyes. Both accepted it and
headed towards the locker room. Of course, Makoto had to pull his swimsuit back
up first. Rin turned his head to look at Seijuro and told him he could go to.
Seijuro declined kindly saying “He was going to save it for later.”
After both Sou and Mako came back, everyone was back to work. The rest of
practice went smoothly and soon it ended. Everyone was happy except for one who
was dreading when everyone would leave. Once they did except for three who went
outside to wait, Nagisa heard a stern voice.
“On your knees in front of the bed, Nagisa.”
 
***** Nagisa's Punishment *****
Chapter Summary
     Nagisa was dead stiff on his knees as he waited for Rin to say, or
     even do something. So far, all Rin had done was sit on the bed with
     his legs crossed. There was an uneasy feeling in Nagisa's stomach as
     he was dreading his punishment, and he hoped that Rin would go easy
     on him. All he did was run around the poolside, and that wasn't so
     bad. Ok yes, he had been warned way too many times and Rin was
     spoiling him with how many he had gotten, but it still isn't as bad
     as what some of them had done.
Chapter Notes
     Sorry, this took so long to come out with, but it deleted three
     times. I am already working on the other chapter so I am now taking
     submissions. Please enjoy!

Nagisa was dead stiff on his knees as he waited for Rin to say, or even do
something. So far, all Rin had done was sit on the bed with his legs crossed.
There was an uneasy feeling in Nagisa's stomach as he was dreading his
punishment, and he hoped that Rin would go easy on him. All he did was run
around the poolside, and that wasn't so bad. Ok yes, he had been warned way too
many times and Rin was spoiling him with how many he had gotten, but it still
isn't as bad as what some of them had done.
Once, Sousuke and Haru had gotten into a fight. It wasn't too bad but threats
and insults were thrown at each other. That didn't sit well with Rin because
fighting was a huge thing he hated. All Rin did was just stare at them until he
had caught both males attention. Then, he turned to go to the locker room, so
naturally, Sousuke and Haru both ran after him. They both made another mistake
again, they touched Rin, without permission.
Everyone gasped as they saw two hands grab at both of Rin's arms. Even Sousuke
and Haru were surprised at what they had done and immediately let go.
"Stay after practice," Rin said in a venomous voice as he continued walking.
Both boys were pale and did stay after practice.
The next day, Rin was constantly being pampered with foot rubs, back massages,
and when he wanted to get into the pool, Rin was lifted. It didn't go unnoticed
by everyone else, everyone saw the limps or the hands that would grab their
owners crotch to sooth them, or readjust them to make it more comfortable.
Nagisa tried to lift his head when he heard footsteps, but it was put back down
which meant don’t lift your head again unless given permission. He did listen
as Rin's footsteps continued before stopping again, this time he heard a
familiar noise. It was the sound of rummaging through a box, which didn't help
him figure out what his punishment. He knew at least one item he would see for
sure during this session.
Once more the footsteps were heard and this time Nagisa saw the feet in front
of him. They stopped and it was clear the punishment was about to begin. Nagisa
silently hoped Rin would be naked, as that is a good sign because it means some
pleasure will come out of this.
The sound of silk sliding against each other filled the room before Rin's robe
fell around his feet. Rin also dropped two things behind him, but before Nagisa
could see what they were for sure, his hair was tugged at for him to stand up.
He obeyed and stood which made Rin get on his knees, naked. No words had been
spoken, as usual, they happen after the punishment.
Nagisa, however, did gasp when he felt the cold air touch his privates. Upon
looking down, he watched as Rin pulled his pants and underwear down to his
thighs before grabbing the limp member in his hand.
He kept watching as Rin moved his hand up and down with the other moving to
grab his balls. Nagisa wasn't that big, to say the least, but he wasn't the
smallest between the two teams. But Rin loved it, how he could fit the whole
thing in his mouth easily, and he could even fit Nagisa's balls in too! The way
Rin always tried different positions to get that pound into his prostate was
always amazing. The thoughts made Nagisa's blood run down to his dick, and soon
it was full mass.
Sadly, that's when Rin stopped to grab one of the items behind him. Which also
was the one Nagisa was no stranger to and seen in anyone's punishment. It was a
ball leash, and everyone had their own. Rei had purple, Haru blue, Makoto
green, Nagisa pink, Aiichiro yellow, Momo orange, Sousuke teal, and Seijuro had
a dark orange to the point it was red.
This was used during every punishment, just for different reasons. Sometimes it
was used for easement into the punishment, and this was mainly for Aiichiro. He
never got punished and when he would, Rin used the ball leash to gradually
build up Ai's endurance. Rin couldn't have him unable to swim because of his
"puppy balls", as Rin called them. It was also a game for the ones (Sousuke and
Seijuro) who could withstand it.
Rin slipped a part of the leash around Nagisa's nuts before he slipped it
through and fastened it. He then continued to rap the end of the leash around
his hand, then Rin made a fist and tugged on the leash. This was a test to see
how much control and movement Rin would have or have to do to get the boy's
attention. Nagisa inwardly groaned as the leash was tight and it would tighten
as it was pulled more.
Finally, Rin grabbed the next item behind him which was a cock ring. The cock
rings were the same as the leashes, everyone had their own, but this time it
was to fit them. Rin moved his hand from the base of Nagisa's cock and put the
cock ring on. Now, it was time for Rin to have some fun.
===============================================================================

Rin was sucking on the underside of Nagisa's cock, as he pulled the leash as
far back as he could. His tongue swirled around the head of the cock as his
hand was around the base of the length.
He finally took the hot organ into his mouth and removed his hand to bring it
behind himself where he started teasing his wet hole. Slowly a finger was
pushed in but a second finger was worked in a while later. Even though Rin has
been pounded multiple times and sometimes at the same time, his entrance was
always tight and juicy.
But for Nagisa, the experience wasn’t so great. It may seem like it because
yeah, a hot guy with a body of a god is on his knees sucking his dick AND also
fingering himself, but his nuts were aching. They were filled with hot cum and
just swirling down there with no way of release. The tugging just made it worse
as the balls would get more heavy with each harsh tug. His knees were also
giving up but Nagisa knew he would get a worse punishment if he dropped. There
was also one other thing that was dangerous for everyone, mostly everyone as
some of the guys are freaks.
It was Rin’s teeth.
Rin would do it on purpose too. He would graze its teeth on the sensitive skin,
and the shark would even take a ball into his mouth to bite it. Sometimes if he
was really mad and felt like he wasn’t getting his point across, Rin would bite
till he drew blood.

Moans and wet sounds still filled the room as Rin continued to deepthroat
Nagisa. He took the smaller male all in without hesitation and would pull back
to the head when he touched the cock ring.

Rin was fingering himself, but he wasn't touching his manhood. Nagisa took note
of that however, it slipped his mind when Rin pulled the ball leash once more.

Slipping his mouth of the cock, Rin watched the string of saliva thin before
letting go and hitting his chin. He was panting and he waited for himself to
calm before he spoke.
"Your punishment is almost over Nagi," Rin said as he unfastened the leach
around Nagisa's balls. The response he got was a frantic nod. Nagisa's tongue
was out of his mouth as he watched Rin reach for the cock ring.

Before Rin took the ring off, he slipped his mouth back on the head of the
cock. Then, the cock ring dropped to the floor for Nagisa to grunt as he bucked
his hips to get more in Rn.
Rin moaned as his mouth filled with hot come and he let his taste buds taste
the cock protein. He tried to sallow it but some cum leaked out and dribbled
down his chin to start dripping on the floor.

Nagisa legs finally gave out and he landed on the floor which made him wince.
He looked at Rin who was in a daze and still very much naked. It did come to
his attention that Rin was still fully hard, but before he could offer to help
the taller male raised his hand.

"Not now Nagisa. You should go home, and I still have to talk with the other
three." He spoke and leaned to plant a slobbery and cum laced kiss on Nagisa's
cheek. Nagisa also placed one on Rin cheek as he got on his shaky knees. His
climax hit hard, and the ache in his nuts didn't help. He did grab his pants,
which had slipt off, and put them on. Rin got up, grabbed his robe and put it
back on to watch Nagisa clothe himself and grab his bag.

"Nagisa, I better not catch you running and fooling around again. But still, I
love you no less. Bye, and see you tomorrow." Rin sent a wave towards Nagisa as
the blonde neared the door.

With a nod and a wave, Nagisa replied. "Yes Rin, you won't. I love you too and
I will be here tomorrow. I promise! I'll bring you some bread to make you feel
better for my behavior." The response made Rin chuckle.
When Nagisa was about to open the door, he heard Rin say one last thing.

"Before you leave, tell them to come in please."
