Disclaimer: I do not own Gravitation, which actually belongs to Maki Murakami.

NOTE: I have not yet decided whether I want this story to have an actual plot or to simply exist for the sheer fun of it -- the fun of creating various excuses for spanking and embarrassing poor Shuichi. (hehehe) You are welcome to weigh in on this question.

In addition, let me know if you have any suggestions for misbehaviors to earn him more discipline or any particular spanking tools you'd like to see used on his bare butt -- hand, belt, cane, paddle, etc.

Please read and review.

Chapter 2: Teasing and Explaining

Both Yuki and Shuichi were surprised to hear the doorbell. "Wonder who that could be?" asked Yuki as he led them into the living room. "Why don't you go to the intercom and ask?" Yuki requested, as he walked into the kitchen.

Shuichi nodded and went to the intercom next to the living room door. He pressed the button and asked, "Who's there?"

A voice on the com replied, "It's me. Hiro."

"It's Hiro!" yelled Shuichi. "Okay, Hiro, I'll buzz you in." Shuichi pressed the button and went into the kitchen, where Yuki was making a pot of coffee. "Hey, Yuki, Hiro's on his way up, so that means I can get dressed, right?"

Yuki turned and looked at him with a smirk. "And, just where would you get an idea like that?" He chuckled at the very thought.

Shuichi immediately got a scared look in his eye, hoping to heaven that Yuki was just messing with him. "But, Yuki, it's Hiro. I don't want him to see me like this -- naked and with a red butt from being spanked! What would he think?"

"He's been you're best friend for how many years? I'm sure he's seen you naked before." They heard Hiro knocking at the door. "Oh, look," said Yuki. "There he is right now."

"But not in a long time, not since we were younger."

"Well, he'll get to see again today. Besides, this is part of your life now, so now's as good a time for him to find out as any. No more arguing, Shuichi!" Yuki displayed the hairbrush to show he was serious, and Shuichi froze. "Now, you know perfectly well it's rude to make your friend stand out there, so go let him in!"

Shuichi timidly walked over to the door, unhooked the latch, and stood behind the door as he pulled it open a crack. He peered around the side to see not only his best friend but also Yuki's brother Tatsuha. "Hiro! I thought it was just you. You didn't say Tatsuha was with you!"

Hiro rolled his eyes. "He didn't show up until right after you buzzed me and I was walking through the door, so I just let him in with me."

"HIRO! You should have told me!"

"Jeez, Shuichi, what does it matter? Tatsuha has every right to visit his brother. Now, are you going to let us in or not?"

"All right." The pink-haired boy sighed and pulled the door further open, remaining safely out of sight behind it. Hiro walked in normally, while Tatsuha entered with his usual swagger, casually grabbing the door and suddenly pulling it closed. It came so suddenly that Shuichi lost his grip on the door and was instantly exposed to his best friend and his "brother-in-law."

Neither of the two guys were expecting the sight before them. Hiro just stared, with his eyes bugged out and mouth hanging open, while Tatsuha looked Shuichi up and down, smiling and licking his lips. Embarrassed and red-faced, Shuichi forgot part of the nakedness rule and covered his privates with both his hands.

No one said anything for a few minutes. Hiro was the first to speak. "Um, Shuichi..."

Shuichi had quickly been trying to think of a diversion to prevent himself from having to explain the situation just yet, and something suddenly occurred to him. "Hey, guys, if we turn the news on now, we can catch Ryuichi's interview!"

It worked. Naturally, Tatsuha immediately changed his tune at the mention of Ryuichi's name. "Oh, my God! Ryuichi is on TV right now!" He immediately grabbed Hiro's and Shuichi's wrists, dragged them over to the couch, sat them down on the couch, picked up the remote, turned on the TV, and flipped through channels until he found the interview. The singer was talking to a reporter about Nittle Grasper's recent album and upcoming tour. "WOW! RYUICHI IS SO AWESOME!" gushed Tatsuha.

While Shuichi was a bit worried about being naked and so close to Yuki's perverted younger brother, at least it was preventing Hiro from questioning him about his odd situation.

Back in the kitchen, Yuki heard the commotion outside and looked into the living room. "Hiro, hey. I just made some coffee, would you like..." He stopped when he noticed his brother sitting between his boyfriend and Hiro. Oh, great! Tatsuha's here, and he's seen Shuichi naked. This is going to get very annoying very quickly.

Hiro called back, "Arigato, Eiri-san! Yes, I would love some. Milk and sugar, please!"

"Sure!"

A few minutes later, Yuki came back into the living room with a tray -- coffee for him and Hiro and some strawberry pocky for Shuichi. He sat the tray down on the coffee table and took a seat on the loveseat next to the couch. It was then that he noticed Shuichi's hands covering his private parts. "Shuichi!" he said firmly. "What did I tell you about that? Hands by your sides! And, come over here!"

"Ohhh, Yuki! I'm sorry, I forgot! Please don't be mad!" he pleaded as he stood next to Yuki.

Yuki smiled. "It's okay. I'll forgive you this time. Besides, with my perverted brother around, I really can't blame you for it."

Tatsuha was too wrapped up in the interview to notice the disparaging comment. However, Yuki was feeling particularly mean, and he grabbed the remote to turn off the TV. "Hey!" shouted Tatsuha. "Turn that back on! I was watching my sweet Ryuichi!"

Yuki ignored him and held the remote out of his brother's reach. After a few tries, he gave up. At that point, Tatsuha remembered that Shuichi was standing there wearing nothing but a collar and snickered at the sight. "So, is it the brat's birthday? Or is there some other reason he's in his birthday suit?" Shuichi blushed furiously.

Finally, Hiro spoke up. "Actually, I'm curious, too. Would someone please explain to me why Shuichi is standing here in front of all of us stark naked?" He got up and walked over to where the other three were.

Yuki looked at Shuichi. "Well, are you going to explain it to them?"

Shuichi stammered. "Oh, sure, I...um..."

Tatsuha interrupted, looking down at Shuichi's privates, chuckling. "Wow, I always said he was just like Ryuichi Sakuma, but I imagine Ryuichi's dick is bigger than that. Damn, Shuichi, have you even started puberty yet?"

"HEY!" he shouted, stamping his foot. "That's mean!"

Hiro then spoke up again. "Well, you gotta admit he has a point. It is pretty small for a guy your age. In fact, it doesn't look like's it's grown much at all since I last saw you naked, what, 8 years ago?" He laughed softly.

Shuichi was livid. "HIRO! You're supposed to be my best friend! You shouldn't be making fun of me, too!"

Hiro laughed heartily. "Aww, don't worry about it, Shuichi. It doesn't matter because Eiri-san is the man of the relationship. Besides, it's nothing to be ashamed of. They come in different sizes. In fact, it's more adorable than anything. If we put a small pink wig on the head, it'd be just like a little Chibi Shuichi in your pants!" Hiro reached down, took it in his fingertips, and gave it a wiggle.

Shuichi jumped back in shock. "Hiro! What are you doing?"

"Aww, I'm just teasing you a bit!" Hiro gave off a friendly laugh, and Yuki snickered too.

Tatsuha then reached down and started to stroke it a bit. (At this, Yuki's eyes narrowed.) This bothered Shuichi even more, and he fell back on the couch. To his embarrassment, the contact and attention was turning him on, and he started to get hard. Tatsuha noticed this and continued to tease him. "Wow, even when it's hard, it's so little!"

He started to reach for Shuichi's parts again, but Yuki was fed up and smacked his brother's hand really hard. "Tatsuha! That's enough!"

Tatsuha rubbed his hand, "Ow! Eiri, what the hell? You didn't do anything when Hiro played with it!"

Yuki glared at him. "Yeah, but with Hiro, it was just friendly teasing. Not so with you."

"Geez, all right!" Tatsuha went back over to the couch and sat down, soon joined by Hiro.

Hiro asked again, "So, why is Shuichi naked except for a padlocked chain around his neck?"

Yuki decided to do the explaining. "Well, as you all realize, Shuichi is a very hyper and childish boy. Most of the time, it's just cute and endearing; in fact, it's helped him become the star he is. However, sometimes it also leads him to do annoying and irrational things and shirk responsibility. Do you agree?" Both Hiro and Tatsuha nodded, so he continued. "Basically, I decided that he needs a firmer hand to help him channel all that energy and youthfulness properly, so I've made him my slave. We are still a couple, but now I'm explicitly in control, and he obeys me. And, I discipline him when he disobeys or otherwise misbehaves."

Tatsuha smiled. "Hmm, he would make a good naked human footstool. And, I'd love to see him serve us all some tea like that. And..." He stopped, however, when Yuki shot him an evil look.

Hiro looked skeptical. "I don't really know how I feel about this. Taking control over someone's life is wrong, even if they need it..." It was obvious he was not completely against the idea, either.

"While you are correct in that sentiment, you should also know he was all for the idea, after a brief moment of doubt. Isn't that right?" Yuki looked over at Shuichi, who nodded happily.

"I want to belong to my Yuki forever and always!" he gushed, and Yuki pulled his naked brat onto his lap, placing both arms around his waist.

"Hmmm. Clearly, Shuichi is in favor of it, so I guess I don't mind, either." Hiro relented. "Still, I don't completely get why he's naked. Is this, like, to remind him of his position, or something?"

"Yes," answered Yuki. "That, and I had to give him his first spanking today." Shuichi started turning red with embarrassment again.

"Spanking?" asked Hiro. "Could you elaborate?"

Yuki started to explain. "We were in my office, and he repeatedly forgot my request to be quiet while I worked, so I told him to work on his lyrics. I thought he was doing that, but then I realized that not only was he not working on them but, in fact, was long overdue on finishing them. It really bothered me to see him be so irresponsible about his work, so I decided that some 'tough love' would be helpful in this situation. I had him strip naked and get over my knee for a hairbrush spanking. After that, I just decided to keep him naked anytime he's in the apartment, from the time he comes home to the time he gets dressed in the morning for work."

"Oh, okay," said Hiro. "That explains a lot." He paused for a moment and then smiled. "When you first mentioned spanking, I was unsure about the whole idea, but the more I think about it, the more I realize corporal punishment could actually be a very useful tool for teaching Shuichi some responsibility and self-control. Thus, you have my approval."

Yuki gently guided Shuichi off his lap and stood him up again. "Here, why don't you turn around and show them?"

The pink-haired boy hesitated. "Aww, Yuki, please don't make me do that!"

Yuki sighed. "Shuichi, they'll probably see your bare red butt sooner or later, anyway, so let's just get it over with now." Shuichi nodded, and walked over to the couch, standing in front of Hiro and Tatsuha, with his butt facing them.

Hiro reached out and gave the well spanked butt a good rub, squeezing each cheek and giving it a few playful pats. "You got it really good, huh?"

"Yeah," said Shuichi. "I really did."

Then, Tatsuha turned his attention to Shuichi's sore tushie. "Wow, so you were bad and got spanked like a little boy, huh? Seems like bro did a pretty good job, too!" He then reached out and gave his butt several rapid, hard smacks.

"Hey, Tatsuha, stop it!" Shuichi quickly turned around to remove access to his butt. Unfortunately, that resulted in the next smack landing on his small privates, and he doubled over in pain. "Ow, ow, ow, waaaah, that hurt!"

Yuki quickly stood up and strode over to the couch, grabbing his brother by the collar. "Tatsuha, I'm warning you! Cut it out! Unless you want to be next!" Yuki gestured to the belt around his waist.

"Ha!" exclaimed Tatsuha. "You wouldn't dare!"

Yuki acted like he was about to take off his belt. "Wouldn't I?"

"I'll tell Mom and Dad if you do!"

Yuki snorted. "Go ahead...but then I'll have to tell them why you got it in the first place! But, if you're fine with that, then by all means..."

"Okay, fine!" exclaimed Tatsuha, and he crossed his arms and sulked.

It was Hiro who broke the uncomfortable silence. "Yeah, Shuichi, I think Eiri-san was totally right to start spanking you. You really deserved it this time, what with your lyrics two weeks overdue and all."

"Shhhhh!" went Shuichi, but it was too late.

He turned to find Yuki looking at him, eyes narrowed. "Shuichi -- two weeks late? You told me the lyrics were only due one week ago!"

The naked, pink-haired singer gulped in trepidation as the other three guys glared at him.

Oh, Shuichi, what have you gotten yourself into now?

Yaoifangirl89, it was originally gonna be just Hiro coming over, but I also included Tatsuha, just for you! :-)
