Happy Birthday Kensei!

Kensei yawned as he wakes up from his sleep. He takes a look at the calendar on the wall which shows "July 30". 'Another boring birthday again for this year…' Kensei sighed and got out of his bed to the bathroom.

It had been a while since he had been accepted as a captain again (along with some of his acquaintances) by the Central 46, Gotei 13, Sereitei, and the 9th squad. Shinji and Rose had been chosen to be the captains of the 5th and 3rd squads whilst he had been chosen to be the captain of his old division. He had fallen in love with the lieutenant of his old squad, the brat he saved so many years ago: Shuuhei Hisagi. That brat had been cute when he was younger but now he had turned into a good-looking and confident man.

He turned the tap on to fill the tub. He had no problems with just slipping into the relaxing warm water; he slept nude anyway. He rested his head on the edge of the tub, thinking back to the first night they were welcomed to return to Soul Society. Kyoraku-taichou and Ukitake-taichou had invited them to have a feast at their favorite restaurant as a celebration.

Kensei cursed his own foolishness for drinking too much sake. He had carelessly told the other captains about his feelings towards Shuuhei. Shinji had started teasing and grinning at him the following day. Ever since that happened, talking to Shuuhei around Shinji made him feel somewhat awkward.

He left the tub and drained the water. Then he walked back to his room and to his wardrobe to get his clothes on for another day as a shinigami.

Shuuhei sat on a chair in the Sereitei Communication office, writing reports of the latest events. He stopped for a moment, thinking about what he is going to do. It is Kensei's birthday and he still hasn't thought of any gifts for Kensei. "Darn! I couldn't think of any gifts for taichou! I guess all I need is to rest for a while… It's lunch break anyway…" Shuuhei thought, placing his brush on the table while standing up from the chair he was sitting at and reached for the door to leave his office. Shuuhei walked out of Sereitei Communication and headed to his usual resting spot.

He laid down on the grass under a tall shady fruit tree. Shinji, Izuru and Renji appeared in front of him. "What are you guys doing here?" Shuuhei asked but his question was not answered. All of a sudden, Renji and Izuru held Shuuhei in place to prevent him from escaping and Izuru muttered "I'm sorry, Hisagi-san…" Shinji held his palm in front Shuuhei's face with a grin. His hand started to glow and Shuuhei looked at it with confusion. Shuuhei suddenly felt drowsy and fainted. Renji immediately grabbed Shuuhei and shunpoed to the 5th Squad barracks along with Shinji and Izuru.

As they entered Shinji's office, they placed an unconscious Shuuhei on a couch. Renji and Izuru sat on another couch at the opposite of the one that Shuuhei is on. Shinji was leaning against the wall. "Are you sure this is okay, Hirako-taichou? I don't think Hisagi-san will like this…"Izuru asked with concern.

"Of course it's fine! It's totally fine! After all, this is for my best friend's sake." Shinji smirked.

"So, how long are we going to wait till we execute the next step?" Renji asked with excitement.

"Tonight, I'll let you know when it's time." Shinji walked to his table and took a paper, a brush and an ink stone filled with ink. He wrote a short note while giggling.

Happy Birthday Buddy!
Here is what you wanted for a long time. I hope you like it! Have fun!

From your best bud and his helpers,
Shinji, Renji (6th Squad) and Izuru (3rd Squad)

Renji went to the table to have a look at what Shinji wrote. A laugh erupted from Renji as he fell on the floor and still laughing. "So that's what you were planning all along." Renji said while rolling on the floor.

Izuru sighed. Renji whispered to Izuru about what was Shinji's plan. His face got red after he knew about it. "Should we get him ready now?" Renji asked enthusiasm at the idea.

"No, not just yet. It's too early now."

(At night)

Shinji shunpoed to the 9th squad captain's office for his usual visit and slammed the door open. "HAPPY BIRTHDAY, KENSEI!" Shinji shouted cheerfully.

"Shut up! Can't you see I'm busy now?" his reply was as expected from the short-tempered captain. Kensei was signing a bunch of paperwork at his desk.

"Aww… don't be mean, Kensei. I have a surprise for you!"

"I don't care!"

"Oh, are you sure?"

Kensei sent Shinji a glare and said, "It better not be something stupid!"

"Don't worry, I can assure you that it is not…" Shinji said as he giggled. He left the office and shunpoed to the forest.

Shuuhei opened his eyes and noticed that he was not where he was this noon. He shivered as the cool night air hit his body and the grass prickling his skin. He realized that he was naked and bind by a kido spell, Way of Binding #1, Sai (Restrain). He then saw Renji and Izuru in front of him. "Abarai- kun! Kira-kun! Where are we and why the hell am I naked?"

"I'm sorry, Hisagi-san…" Kira apologized. "Taichou ordered me to assist Hirako-taichou on whatever thing he is going to do for Muguruma-taichou's birthday but it turns out to be this… I really wanted to release you but, unfortunately, I can't."

"I don't care! Just let me go!" Shuuhei yelled while trying to dispatch the kido spell.

"Stop yelling, Shuuhei. We can't let anyone know about this." Renji said as he jabbed Shuuhei with a syringe that was labeled with "Lust Potion" and injected the fluid into him.

"What are you planning to do with me!"Shuuhei's vision slowly started to blur and his body started growing hotter.

"I can't tell you but you'll see. You need to be quiet for now." Renji said and tried to gag his mouth with a white cloth over Shuuhei's mouth. Shuuhei recognized the cloth: it was his sash. After a few failed attempts, Izuru held on to Shuuhei's head to keep him from flailing.

Shuuhei muttered a line of curses but they were muffled by the gag. Shinji came out of the bushes and said "Let's go!"

The three of them shunpoed to Kensei's private quarters at the 9th squad barracks and opened the door. Renji placed Shuuhei at Kensei's bedroom on a futon laid by Izuru while Shinji looked to see any signs of Kensei coming.

"We are done. Let's get going." Renji said as he and Izuru left the room.

"Good luck, Hisagi-san…"Izuru said. Shinji pasted the note he wrote earlier on Kensei's door. The three of them shunpoed from the place and left Shuuhei there.

Shuuhei felt Kensei's reiatsu slowly approaching the private quarters.
