Karasuno was preparing for the Spring Tournament that was scheduled for the next month. Everybody had high expectations to win and finally make the crows a powerhouse once again. As it was usual prior to these competitions, the team checked on progresses of muscle gain and height of each one of the team members. Not only it gave insights on where to focus the future training sessions but also it gave the team a sense of competitiveness. The one that run through these measurements usually was the nurse of the school.

Hinata was nervous about the physical measurements. Although Nishinoya was the shortest of all, he was still scared not to have grown at least some cm. He didn't know what was the normal growth rate in each of these instances so he decided to take a look at the reports of his teammates from previous years.

He didn't want anyone to know he was going to look at their data, so he decided to arrive early the next morning to "practice" and check on Daichi's notes, which where stored in the locker room.

It was 5am, a cold morning, but for Hinata it felt that somehow he was doing something secret and mischievous. He went to the students room and took the key to open the locker room. After he got inside he went straight towards the archives. He opened them up and started searching…

Daichi's handwriting was easy to understand. He found a table with the data he was looking for:

Daichi: height in the first year 174cm and in the second 176cm. 2cm… Sugawara: height in the first year 170cm and in the second 175cm. Interesting, 5cm gained in one year. Asahi: height in the first year 180cm and in the second 186cm. Well… something I expected from our ace Tanaka: height in the first year 178cm Nishinoya: height in the first year 160cm

"Okay, so on average 4cm of growth each year… I may have grown but I'm not sure if that much…" thought Hinata. "At least I know I wave grown 2cm, which is the minimum"

He was passing the page when a paper felt on the floor. It had another table and the title was: CONFIDENTIAL - Sensitive students data

"What is this about?" wondered Hinata.

Hinata read: As part of our year on year students' growth measurements, to provide data to universities for studies and surveys, we are also asking students to fill out a form the following data: built, penis length and girth. This information is voluntary and relies of the information each of them provide.

"Wouuuu! Is this seriously something we do here in Karasuno? All team members dicks' data are here! Flaccid and Erect!" Suddenly he felt like someone had punched his tummy. "Do I have to measure it? How do I measure up to everyone else? I know this is an invasion on privacy… Should I see this?" His dick started boning up… "Just a quick peek!"

Last year data read:

Daichi: mesomorph | flaccid penis 8cm long and 8cm girth | erect penis 14cm long and 12cm girth Sugawara: ectomorph | flaccid penis 6cm long and 7cm girth | erect penis 11cm long and 10cm girth Asahi: mesomorph | flaccid penis 10cm long and 9cm girth | erect penis 15cm long and 13cm girth Tanaka: mesomorph | flaccid penis 9cm long and 9cm girth | erect penis 16cm long and 12cm girth Nishinoya: ectomorph | flaccid penis 7cm long and 8cm girth | erect penis 13cm long and 11cm girth

"Wouuu! Tanaka has the biggest one! Is it really 16cm long? That's big! And Asahi has the girthiest! Suga is small in comparison… I have seen it flaccid in the locker room and the data is probably correct. I can't imagine sempai lying… However, are the other ones true? Mmm… I have never measured mine! How do I measure up to Nishinoya for example, we are similar in body types."

He decided to take a picture of the page with his cellphone and close the files. He was returning the pages to the archive when Nishinoya suddenly entered the room.

"So earlt here Hinata! What were you doing? Are those the archives that have our physical data? Checking out my files to see how great I am? As the libero of the team I have improved a lot my defense and I am able to return the ball to the other side almost from anywhere in the court!"

"Yeah… Sure, you are the strongest sempai!"

"Let me see! Let me see!"

Nishinoya got close to the archive and took the files that were the ones on top. He opened them and found the CONFIDENTIAL data… He looked at it and looked back at Hinata.

"What is this?" He read the info and looked at the table. "So you were looking at our measurements eh?" He said with a smirk. "This is supposed to be secret you know… It seems you couldn't contain yourself. Are you surprised? I know you guys may think that as I am the shortest I was the smallest one, but that's not true it seems! Suga's one is tiny…" He looked and Hinata and saw the tent in his trousers. "Ahh, were you perhaps aroused by these numbers? Imagining our dicks in your mind?"

"No Nishinoya, its not what it seems" He tried to cover his bulge. "I was only trying to look at height data and that table came up!" He tried to take the data back but the libero was faster. Shoyo's cellphone fell down as the older student unintentionally moved the table. The screen was on and it showed the picture of the table.

"So not only did you see this data, but you also took a picture of it without permission… So… Misbehaving! I didn't think you could become someone like this haha! Should I tell Daichi?" His grin was even bigger.

"No please, I'm sorry! I just wanted to check how mine measured up to the others!"

"Mmm… I wonder… Come see me at the end of the training session today. Take this!" He passed the table back to Shoyo and positioned so the younger student took it with both hands and the table was in front. He took his cellphone out. "Now, say cheese! Haha! Your boner is showing!" And took the photo.

Hinata was red as a tomato. He quickly hid the files and stood there looking down.

"Don't tell anyone please, I beg you!"

"That will depend on how you behave yourself haha. I must admit I always wanted a obedient kohai. It seems now I have one. See you later. " And with that said, he left the room.

"I am so embarrassed… and hard." He closed the room and left.

The day passed by slowly for Hinata. "What have I done! And why do I have to get hard every-time I think about the situation?!"

After classes he went to the locker room as usual, but as he entered, he couldn't stop himself from looking at his sempai changing clothes and looking at their bulges. Tanaka had a good package and he remembered the numbers… "16cm last year. Did it grow this year? Is it bigger now?" He saw Nishinoya looking at him with a cheshire cat grin. He immediately went back to his own business.

"Hey shrimp. What is taking you so long?" Kageyama was already in his sport uniform.

"Coming!" Said Hinata with his cheeks burning.

—

At the end of the workout Nishinoya was waiting for him. "We are going to look for something that was left in my classroom. See you tomorrow guys" He exclaimed.

He took Hinata's hand and run to the main building. He guided him to a storage room without any windows, closed the door and turned on the lights.

"Nobody will bother us here haha. This is my secret spot."

Hinata was nervous… he looked at the room but he only saw boxes and papers.

"What do you want Nishinoya? Could you please delete the photo?"

"Have you deleted yours? Give me your phone" He extended his hand.

Hinata became red again. He gave Nishinoya his phone and as Nishinoya looked at the contents saw that the table was still there. "So you are interested in these numbers… ah? You dirty boy. You were looking at Tanaka's to check if what he said was right huh? We have grown this year tho. Mine is definitely bigger than last year." He said grabbing his dick through his trousers. "Wanna see?"

Hinata was speechless. He wanted to, but he didn't want to become entangled in the trap…

"Or maybe you want me to help you measure yours and see how it compares to our data last year… have you ever measured it?"

"No, I haven't… I think I'm on the smaller side tho…" He said looking down.

"We will see… At least you have energy haha!"

Nishinoya came closer and whispered to Hinata "Now, remove your shirt and shorts and follow my commands, if you do not want the others to know about the pic"

Hinata slowly took off his clothes until he was only in his boxers tenting up. There was a wet spot where the head of his dick was.

Nishinoya watched this with interest. He no longer tried to hide his boner and looked at the younger student intently. He didn't have such defined muscles, but you could see he was trying his best. No happy trail yet…

"Seems you are pretty excited to show your sempai your dick" He said getting closer and pointing at the stain. "Not that I can say something different…" He looked down at his huge boner. "See what I meant with I have grown? Hahaha! If you behave I will let you take my new length and girth measures." He took off his shirt. "Now you can see some muscles. I know you know them… What were my numbers in the report?".

Hinata was so turned on! He had never seen another hard dick before. It looked so big… The six-pack and also the attitude of his sempai drove him nuts. He couldn't stop looking at it. The shorts wear baggy and he couldn't see the outline of the dick. " 13 cm long and 11 cm in girth. But it looks huge now."

" We'll see that later. Take off your boxers now I want to see that little pecker." Nishinoya couldn't contain himself.

Hinata looked down and started removing his underwear. First came the bush. It was red as his hair. Not densely populated, but not shaved either. Second came the cock. It was uncut. Standing there and you could see the veins. Third came the balls almost without any hair. They were small and firmly attached to the dick.

" I thought it was smaller, but it doesn't seem that much. It actually looks almost the same size as mine last year. Maybe a little bit smaller though. Are you as little as Suga? Probably he was smaller the first year he was here, but we only have the data from last year. I know mine was similar to his last year but I don't know how you can satisfy someone with a dick so tiny. I mean. 11 cm. Is it even able to enter a cavity? Is it able to reach this sweet spot? I'm a virgin. Maybe we can answer that question together. Haha. If you feel like it. For example. Have you, Hinata, even thought about Suga's cock at all today. You have all our data and I have seen how turned on you were. Tell me and please don't lie."

"I… well actually I haven't pictured in my mind Suga's penis at all. Can I be frank with you? Can I trust you? I mean you have total control over me now. Do you have that picture and now you have seen my dick. "

"Yeah… sure. Please tell me your thoughts I won't judge. I know how naughty you are. And I'm seeing how your cock is twitching right now. I know you're excited to tell me this. What were your thoughts when you saw that table. "

"Okay. I had never seen a boner hope another person other than myself until today. It was hard to imagine a 16 cm penis. Would I be able to handle it with my hands? I have small hands so probably I couldn't even cover the whole girth… On the other hand, you were the one that found me today in the locker room looking at the files. Also, as you mentioned before you are shorter than me. So of course, I pictured your dick in my head too. I imagined 13 cm was OK for your size. I also read online that it was around average size of men. You are super sporty and sexy. I wish I had your defined muscles. You were someone I aspire to be. And I so yeah, I'm very excited right now to see you as aroused as I am."

"Huh. So you actually want to see mine. Don't worry, I will show it to you. But first let's measure yours. There was a measuring tape here I don't know where. Here it is. Should I do it or do you want to do it?"

"You know what I want? Stop teasing me."

" Okay okay. Someone got his courage out. I like it. Let's see. You need to measure it from the bottom to the top." He pushed the measuring tape to remove any belly fat too hold of Hinata's cock. He shivered. " It's 11 cm long. You are the same size as Suga's last year. Don't worry you have still room to grow. I know you can do it. I can lend you my bathmate if you want."

" Damn. We were just saying that one of the little as this one doesn't cough the attention of anyone. I told you I was on the smaller side. Check the girth too please."

" It's 9 cm. I think that is smarller than Suga's. "

"Yeah, it is… Damn"

" I think it's cute, tiny but cute. And it looks very energetic. I can cover it all easily with my hand. My fingers even cross each other. " This movement made Hinata close his eyes.

" That felt good."

" Do you want to see mine now? Here it is." he took down his shorts and boxers in one movement. His dick bounced. It was true he had grown. His was uncut with a big head and huge veins that crossed the shaft. Nishinoya was so proud. "Measure it."

"Okay" Following the instructions from before, Hinata took the dick on his hands and started using the tape. He was so impressed with the size. " I hadn't imagined it would be like this, so huge, so strong, so manly. It's 16 cm now. The Tanaka said his was last year. Woah and the girth is even more impressive. 13 cm. I cannot grab a hold of it completely. How did you do it? How did it go so much? "

" It's a secret I'm willing to share it with you. But only if you do something for me. And I know I'm not asking that much because you know you want to taste it. Can you put it in your mouth?" He laughed.

" I can try" with that said Hinata opened his mouth, took out his tongue and tried to enter as much as he could of Noya's dick inside.

" Careful with the teeth. Cover them with your lips."

Hinata gagged. He was only able to cover 3/4 of the cock.

" That's more like it. Mmm. Your mouth feels amazing. Close your eyes if you like it. Yeah, just like that. " Nishinoya put his hands over the younger boy head and pushed slightly to enter more of his dick into Hinata's throat. The boy was ecstatic.

Hinata moaned and gagged. He couldn't breathe. But he didn't want to take it out either. He started moving. He's strong doing circles around the shaft.

" oh, my God. You're a natural. Fuck. Eat it all. Today this is for you. Take my huge cock completely inside. Ahhh" He pushed harder now and started moving. Fucking Hinata's face.

As he gagged, Hinata I started to feel that he was able to take more inside. He finally got to the point where his nose was reaching his sempai pubes. The taste was amazing. It was a strong but delicious. Even as Noya started fucking his face like a rabbit he was enjoying the moment. He started breathing through his nostrils. I started feeling that the older boy balls were constantly hitting his chin. It felt incredible.

"Yes. Take it all inside. Oh my God. You are so good at this. " he took out his dick and started hitting Hinata's cheeks with it. " so you like it don't you? What do you want me to do with it? "

" Please sempai. Let me finish what I started. I want to suck it dry. I want to feel it deep in my throat. Smell your pubes. Feel the girth. Gagging on it. And taste your cum."

" So you're finally true to yourself. This is what you wanted to do with the data. Imagine yourself choking with our big cocks inside your mouth. Touching yourself like you were doing right now. Now, suck it.

Hinata open up once again and in one swift movement, he took it all. He took his hands and grabbed the older boys butt.

" I'm so close. Please don't stop moving. Oh fuck!" As he came hard, he felt Hinata's cum hitting his feet.

Hinata couldn't move. The taste was a little bit bitter but sweet. He hadn't needed his hands to cum.

"I am so good that you came just like that. Without any help. That's my cock for you. Jesus. That was one of the best experiences of my life. Take it all and drink it you little horny boy."

Hinata cleaned it all. He couldn't take his eyes off the beautiful, sexy, strong boy he had in front of him.
