Morning at the lounge:
Everyone was working like always, suddenly Gou saw something that was bothering him about Yuujirou.

Yuujirou: "Is something wrong?"
Gou: "N-No... Nothing."
Yuujirou: "Okay..."

Gou was still a little confused, about what was bothering him. He walked toward Kuugo and Rai.

Kuugo: "Is something wrong, Gou?"
Gou: "Something is bothering me about Yuujirou, but I don't know what..."
Rai: "Really?! You didn't notice it."
Gou: "What?"
Kuugo: "Well... Yuujirou didn't noticed it, too, so..."
Rai: "It's strange, that Yuujirou haven't notice it yet."
Kuugo: "Yeah... he should be the first one, to realized it."
Rai: "He's too focus on work."
Kuugo: "Yeah..."
Gou: "Can you finally explain to me, what's going on?!"
Kuugo and Rai: "No."
Gou: "Why?"
Kuugo: "Because... you just need to be a little curious."
Rai: "And plus, you should understand, now."
Gou: "What do you mean?"
Kuugo: "He didn't realize it, like Yuujirou."
Rai: "It's because we are the best."
Kuugo: "Yeah!"
Gou: "What did you do?"
Kuugo: "You should know it, now."
Rai: "Yeah, you don't feel different."
Gou: "No... actually, I'm feel really nice, right now."
Kuugo and Rai: "You're hopeless."

Suddenly Sousuke arrived.

Sousuke: "Why did you do that to Yuujirou and Gou?!"
Kuugo: "For the fun."
Rai: "The funniest thing, is they didn't realize it."
Sousuke: "Really?!"
Gou: "Yeah... I don't feel different."
Sousuke: "You're hopeless Gou."
Gou: "Can someone explain to me, what's going on, now?!"
Sousuke: "Normally, I should tell you, but... I will see, if you're smart enough, to notice it."
Gou: "Tell me!"
Sousuke: "Anyways, I have work to do."

Sousuke left the lounge.

Rai: "He said that, but he didn't realized it, too."
Kuugo: "He saw it on everyone, but not on himself."
Gou: "Please, tell me..."
Kuugo: "Just be a little curious."
Gou: "That's not helping."
Rai: "Actually, it should help you."
Gou: "Fine, I will go and see Yuujirou."

Gou returned to the kitchen , and started to think, about what Kuugo and Rai said.

Gou: (I have to be curious...)

Gou looked at Yuujirou.

Gou: (Could it be?)

Gou walked toward Yuujirou, and looked inside his trousers.

Gou: "///!!!///"
Yuujirou: "///What are you doing?!///"
Gou: "///You're not wearing your underpants!///"
Yuujirou: "///What?!///"

Yuujirou looked at himself, and saw that his underwears were gone.

Yuujirou: "Did I forget to put one?"
Gou: "You really are stupid to forget this... Wait!"
Yuujirou: "What?"

Suddenly Gou realized that he didn't have his underwears, too.

Gou: "///Me too...///"
Yuujirou: "///What?!///"
Gou: "I don't have my underpants, but I'm sure I put one this morning."
Yuujirou: "Then... why we both doesn't have our underpants?"
Gou: "I think, I know why."

Gou and Yuujirou returned to where was Kuugo and Rai, but they were gone.

Gou: "They were here, just a short time ago."
Yuujirou: "Did they leave?"
Gou: "Maybe... I guess we have to stay like that."
Yuujirou: "///Well... maybe, it's not that bad, after all.///" *Look at Gou*
Gou: "Did you say something?"
Yuujirou: "///Nothing!///"
Gou: "Anyways, I will make sure those two, will never do that again, when I will found them."

Gou returned to the kitchen, and saw a note, with a little box.

Gou: (A note... for me?)

Gou read the note:
'Sorry for stealing your underpants, for excuse ourself, we decided to give you a gift.'
Gou opened the box.

Gou: (///Yuujirou's underpants!... Should I give him back his underpants?... Maybe, I will keep it, It's just a underpants... with his smell... this good smell... he will not be mad at me, if he don't find out.///)
Gou: "///Maybe... Their little game is not that bad, after all.///"

Kuugo and Rai were looking at him, hiding outside the lounge.

Kuugo: "Looks like, he like is gift."
Rai: "Yeah... Should we gave him, Sousuke underpants, too."
Kuugo: "Well... I'm more interest in your underpants, so... okay."
Rai: "Me, I'm interest in yours, so... let's give Sousuke's underpants to him, and let's give Gou's underpants to Yuujirou."
Kuugo: "Okay."

During the breakfast, the following day after Yuujirou's confession, at the Lounge…



Gou (watching Yuujirou): "Mmm"

Yuujirou: "/////////// Sempai why are you watching me like this?"

Gou: "//////// Because Yuu-kun is very cute"

Yuujirou: "///////////// sh-shut up…"

Gou: "Uh? Why I'm saying the truth…"

Yuujirou: "///////////// S-Sempai…"

Gou: "Uhm?"



Suddenly Yuujirou stood up and went in Gou direction he grabbed him while he was eating a biscuit and coming closer, they shared the biscuits and also a good kiss, until…



Yuujirou (realising): "//////////!!!!!!!!"

Gou: "Uh? //////////// Yuu-kun why you stopped? It felt so good ///////////"

Yuujirou: "//////////////!!!!!!! W-what… h-how could I do that?"

Gou: "Why don't you liked it?"

Yuujirou (letting Gou fall): "I'm sorry Sempai…"

Gou: "Ouch, Yuu-kun watch what you do…"

Yuujirou: "S-sorry… I-I… G-Gou"

Gou (with an interrogative expression): "Uh?"

Yuujirou: "/////////////// I can't control myself"



Yuujirou lay down on Gou and kissed him again, Gou didn't do any repulsions, he just let him do whatever he wish, also because he was enjoying too and so much…



Gou: "Mmm, Yuu-kun taste like chocolate… and it's milk chocolate…"

Yuujirou: "/////////////"

Gou: "Me instead?"

Yuujirou: "J-jam //////////// Peach jam…"

Yuujirou: "I-I ///////////// I love it!!!"

Gou: "Yuu-kun why don't you give me another taste of you?"

Yuujirou: "You already took… and also before…"

Gou: "///////////// About that…"

Yuujirou: "/////// You put your finger…."

Gou: "But you liked a lot…"

Yuujirou: "//////////////// B-because…"

Gou: "What?"

Yuujirou: "Was my first time and was with you… I couldn't wish more"

Gou (hugging Yuujirou): "My silly chocolate dog…"

Yuujirou: "/////////////"

Gou (jumping on Yuujirou): "And now, let have another deep taste of you…"

Yuujirou: "S-sempai w-wait please… it's tickling let my s-shirt… G-Gou…"



Instinctively Yuujirou gave a kick to the table and some milk fall on him making him all wet…



Gou: "Ops, Sorry… forgive me Yuu-kun"

Yuujirou: "////////////// *sigh*"

Gou (sad): "I'm sorry"

Yuujirou: "My clothes… my parents will kill me…"

Gou: "W-we can use my washing machine…"

Yuujirou: "…"

Gou: "Please forgive me"

Yuujirou: "I'm not angry…"

Gou: "I can feel your look in me, and hurts…"

Yuujirou: "///////// Don't think to this too much…"

Gou: "Maybe it's beeter if you go to change we will open in some minutes…"

Yuujirou: "You too you can't cook in your pijamas"

Gou: "////////////// Yes, you're right…"



Then Yuujirou went to change in the bathroom and Gou in his room…



Yuujirou: "Sempai… why if I think about you ////////////"

Gou: "Yuu-kun… you made me so /////////// hard… how can I resist to you…"



Then again downstairs when finally also Kuugo arrived…

Kuugo: "Oh you both are smiling… something happen that I don't know?"

Yuujirou: "//////// Erhm…"

Gou: "/////////// Well"

Kuugo: "Oh but Yuu-kun you are wearing the same clothes as yesterday…"

Yuujirou: "//////////////"

Kuugo: "I know but instinctively you blushed when I said this… that means"

Yuujirou: "/////////////!!!!"

Gou: "Cccc //////////////"

Kuugo: "Oh-ho!!! I guess it!!!"

Kuugo: "And Gou wasn't able to resist to your fashion look, right?"

Gou: "/////////////// Ahem… You know, w-watch him, how can someone resist to this cute face… and body… and /////////////////"

Yuujirou: "This is enough don't continue…"

Kuugo: "Why not? Thigs were becoming very interesting!!!"

Gou: "//////////// Kuugo why are you so interested?"

Kuugo: "Dunno, maybe because yesterday I didn't have my usual night…"

Yuujirou: "You and Sousuke do all the nights?"

Gou: "Poor him…"

Kuugo: "Uh? Why? He likes instead…"

Yuujirou: "////////////////"

Gou (watching Yuujirou with a expression like, can we do it too?): "/////////////?"

Yuujirou: "Ehm… Em… S-Sempai… I-I…"

Kuugo: "Yes?"

Yuujirou: "Oh, A customer, let me take his orders… properly…"

Gou: "O-ok…"



After some hours of hard works, around 6 pm…



Yuujirou (entering in the kitchen): "Gou, I'll take a bottle of water…"

Gou (noticing something strange in Yuujirou): "Sure… Uhm?"



Yuujirou put himself at 90° and immediately Gou, watching Yuujirou's butt, realized what was…



Yuujirou: "Uhm, water, orange juice or tea? …"

Gou: "Yuu-kun, you have something weird today…"

Yuujirou: "//////////////// What do you mean?"

Gou: "I dunno… Oh of course I know c'mon tell me…"

Yuujirou: "I don't know what are you talking about…"

Gou: "You sure…"

Yuujirou: "///////////////////"

Gou (puling Yuujirou's trousers): "Bingo!"

Yuujirou: "////////////////////// Sempai how can you…"

Gou: "Yuu-kun is not wearing any pants today…"

Yuujirou: "//////////////// you made me all wet before and I didn't have another pair of pants"

Gou (hugging Yuujirou from the back): "Wanna know a little secret Yuu-kun?"

Yuujirou: "/////////////////////"

Gou: "Before when I jumped on you… yes I mean … and also now… seeing your butt… ///////////////// Well I don't have any pants… that are able to contain me when I'm /////////////// you know…"

Yuujirou: "//////////////// S-sempai… what is the thing I'm feeling?"

Gou: "////////////// Yuu-kun… I don't wear pants too…"

Yuujirou: "//////////////!!!!!!!! Gou!!!!"

Gou: "//////////// I know but you make me in this situation…"

Yuujirou: "I'm sorry…"

Gou (squeezig Yuujirou's butt): "Yes and now it's punishing time…"

Yuujirou: "Aaaahhhh, S-Sempai… go easy…"

Gou (pushing Yuujirou against the wall and starting t explore hi body): "Oh Yuu-kun I can feel you are so hot…"

Yuujirou: "W-well it's your fault…"

Gou: "So maybe you can punish me too"

Yuujirou: "/////////////// You make me want to do so badly"

Gou: "Then do it…"

Yuujirou: "But we have work…"

Gou: "Let's take a pause…"

Yuujirou (wagging, tickling Gou): "///////////// Sempai!!! Wait some seconds…"

Gou: "Ummm"

Yuujirou: "Meanwhile you can take off those trousers…"

Gou: "Oh that's obvious…"

Yuujirou: "Wait me in the bed…"

Gou: "Huff… Yuu-kun!!!!"



Gou take off all his clothes in the kitchen and using the second stairs went upstairs in the room under the sheets… a visible tower was making the sheets dirty, who knows what is…

Mean while Yuujirou wrote a paper and then take oof all his clothes too and went upstairs were…

Well… only someone with a goos ear could hear theirs pleasure screams and moans… This someone was Kuugo… In fact…



Kuugo (entering in the kitchen): "Gou? Yuujirou?"

Yuujirou: "Nnnggghhh"

Gou: "Yuu-kun!!! S-so tight…"

Kuugo (starting to nosebleed and touching himself): "Ah they are… Crap, my phone is dead… Unfortunately this time… *sigh*"

Yuujirou: "Hhhhaaaa so deep"

Gou: "T-Take it all…"

Kuugo (noticing Gou's and Yuujirou's clothes on the floor): "Uhgn… they take all the fun… I want to have fun with them too… Uhm… but probably Sousuke will not agree in this…"



After some seconds Kuugo saw a paper on the table and started to read it…



Kuugo: "Uh? A paper? Kuugo me and Gou will take a pause … (Yuujirou watched Gou naked) ok, a long pause… dishes are ready so please make you all the works for us… and //////////////// wash your hands before…"
