You know the frustrating feeling when you constantly try to teach someone something but they don't get it? Not cuz they aren't smart, they just don't want to learn or maybe they want to make you angry and tease you?

Harry has been feeling like that over a month since their math teacher assigned him to tutor Zayn, the bad boy, who doesn't give a flying fuck about school, and you can guess how much he hated math, so even though Harry is a nerd who knows probably more than he should about math, he couldn't teach Zayn anything, not that he didn't try different methods, cuz he even made Zayn flashcards it took him hours to make them just so that Zayn rip them apart cuz he was tired of studying.

Harry had one week to help Zayn, he was lying on his back on his twin-sized bed trying to come up with something new. something interesting enough for Zayn to make him listen for once. Zayn was always distracted with something, Harry caught him 100 times spacing out and when Harry would try to shake him he would snap at Harry for touching him.

"what the fuck should I do with this overconfident selfish asshol-?!" it was the light bulb moment. "his ass," he whispered "you are so smart Harry." he prised himself, if his plan works, Zayn could even be the top student in next exam.

Ingredients for his ace plan? Some hard and simple math problems and....A ruler.

An hour later Harry took his backpack and made his way to Zayn's house, they always studied there cuz Zayn's family were at work till late at night and they could use some peace.

20 minutes of walking, Harry was in front of Zayn's door, he knocked a couple of times but Zayn didn't open the door, Harry was 99% sure that he was sleeping, it wasn't his first time that he forgot Harry was coming.

So Harry did what Zayn told him to do when something like this happens, he jumped to their back yard, and climbed over the tree next to Zayn's bedroom and tapped the window, Zayn didn't wake up, so he tapped harder calling Zayn name, Zayn moved a little opened his eyes and look around till he saw someone out of the window. the Zayn malik scream land fell of the the bed, Harry wanted to laugh but he had to keep himself on the tree, when Zayn finally registered what was happening he opened the window and let Harry in.

"that was very manly scream Zayn." Harry let it out, he laughed slapping his knees, Zayn just stared at him with a bored gaze.

"Are you quite done? Can we start now I have planned for tonight." Zayn said sitting on his queen-sized bed.

"plans? You mean the party Louis is trowing tonight?" Harry questioned, taking out his ingredients.

"a ruler Harry? What are you gonna measure? My dick size? So you can tell your friend how big it was?" typical Zayn so full of himself.

"you'll see," Harry stated seriously, he opened his notebook "so there are 10 questions here, answer them."

"When are we gonna stop with this stupid quizzes? You are so booooring." he was tired of this process, take the quiz, fail and Harry explaining every single question, and Zayn just gazing at Harry's lips dreaming about things he shouldn't dream about.

"This is gonna be different Zayn trust me." Harry said, placing his glasses on his eyes.

"the thing is i. dont. trust. you." Zayn spoke, stressing on trust.

"oh well I guess that's your problem," Harry opened the novel he brought with himself and started reading "you have 30 minutes Zayn's you better start."

"wh- who do you think you are? you cant order me around!" it was obvious that he was just waisting time.

"You have an exam in 6 days, 29 minutes Zayn." he went back to reading, ignoring Zayn altogether for 29 minutes.

And Zayn? He ignored the questions, he drew dicks on the paper for 30 minutes, Harry was watching his every move, and he was so ready to teach him not only math but some manners too.

"alright, times up." Harry closed the book and took the paper from Zayn.

"Finally!" he made a move to stand up, Harry took his wrist "what are you doing don't touch me!"

"We have at least 2 more hours Zayn, sit." Harry let go of his wrist.

"what you think it's a 5 mints process? I have to get ready for the party nerdy, see ya tomorrow."

"yeah I don't think so," Harry stood up in front of Zayn.

"get out of my way Harry, you aren't my father!"

"no Zayn I'm not. but we have something to do here, 1 hour ok? and I'll let you go." Harry asked softly, looking deeply in Zayn's eyes 'his eyes are so green.' Zayn thought.

"ugh ok, just one hour, not that its gonna change anything." Zayn crossed his arms on his chest sitting down, he was hopeless, he couldn't learn shit, what was the point of trying?

"I can assure you this time you gonna learn something," Harry said smirking.

"What is that stupid smirk? What's wrong with you today?"

"I'm gonna make a deal with you."

"What is this a game? I don't have time for this!" he stood up again.

"nope, no Zayn you said an hour and we are gonna make the most of it." he made him sit down again "so hear me out," he turned Zayn face toward himself, he gathered every ounce of courage he had and took the ruler and showed it to Zayn "I'm gonna explain one of these questions for you and you'll listen then I'll ask some question similar to that if you answered correctly then we move on but if you don't then," he paused, Zayn was looking at him confused "you'll get punished."

With that Zayn burst out laughing so hard that his eyes were teary "Harry it was the best joke ever hooooh."

"I'm dead serious Zayn, whatever we try won't work."

"what you gonna do? Spank me? The fuck Harry!" Zayn was getting angry, he didn't want to stay an listen to Harrys bull shit anymore.

"Why are you so afraid? I'll explain them first, nothing to be afraid of if you listen to me," Harry knew exactly what to say, Zayn would do anything to show him he is not scared.

"I'm not afraid of you," Zayn argued "but this idea is stupid." he crossed his arms over his chest.

"worth to try though, so what is it? Are you gonna keep pouting or we can start?" Harry askes obviously amused.

"I'm not fucking afraid styles, do your best," he sat in front of Harry waiting for him to start.

Harry began to explain the first problem for Zayn, it took him 10 minutes to explain it, Zayn was concentrating trying to understand he thought he did.

"it wasn't that hard styles." Zayn said, smirking.

"ok then here answer this one," Harry gave him a problem similar to the one he just explained "5 minutes Zayn."

Zayn was struggling, he couldn't focus on solving it, the thought of getting punished wouldnt let him.

"ok times up, lemme see," Harry pushed his glasses up a little, as he expected, it was wrong like too wrong to get ignored.

"Zayn, it was exactly like the one I just explained!" Harry huffed, took the ruler and said "over my lap Zayn."

"huh never," Zayn made move to stand up, Harry took his right arm "Nah ah you come here, take your punishment maybe you listen to me next time." Harry laid him on his lap, Zayn was moving like a fish in his grip, but he managed to keep him still.

"the answer was 25, so let's give you 2+5 spanks with the ruler, first 3 times you answer wrong I'll give you over your trousers, after that, you'll be butt naked." he landed the first spank.

"ow! Harry you are crazy let me go!" Zayn spat, angrily, he couldn't believe the nerd is punishing him.

"6 more Zayn." he spanked him hard enough to cuz pain but not get him bruised.

"Harry it hurts!!" he was on the edge of crying, Harry didn't say anything, he just kept spanking him.

"ok it's over now." Harry said, helped Zayn to sit on the bed.

"gimme two of those pillows asshole," Zayn said maintaining himself from screaming and crying. he was hard, it was so embarrassing.

"there you go, now next question." Harry gave him the pillows and watched how Zayn put one on his lap, 'oh oh he is hard.' he wanted to see him all frustrated, so he jumped on the hardest question.

"Since we have only 40 minutes left, imma explains the most important one, you should give me 3 answers, so listen to me." Harry tried to give him a warning, well he was wishing he could take him over his lap again, 15 minutes later Harry was done.

"Alright, you have 10 minutes, start." he watched how Zayn bent a little to come close to the paper, how he was trying to grind his dick on the pillow, how his eyes show nothing but lust.

"Are you done?"

Zayn looked up and shook his head, he gave the paper to Harry and refuses to make an eye contact with him.

"ok it was 13, 2.5, 17 you answered all wrong." Harry faked disappointment, he was actually looking forward to punish him again.

"I'm sorry! I swear i-"

"nope you'll get 15 on your boxers, come here" Harry tapped his lap, Zayn grunted but he did what he was told.

"Take your pants off," Harry ordered, he was getting confident.

"can you lik-"

"now Zayn." and he did

oh, batman boxers.

"so, batman?" Harry said, landing one spank with his hand.

"don't you dare to-" Harry gave him a hard spank with the ruler.

"I don't think you are in the place to tell me what to do." he landed 3 more without stopping.

But something made him hesitate, Zayn was grinding on him, subconsciously, whimpering every now and then so Harry decided to tease him a bit more, he would rub the ruler on his boxers then he would land it as hard as he could.

"H-Harry, ow!" Zayn said, with tears in his eyes, but the growing boner on Harrys lap told him he is enjoying it.

"and," he landed the last one "15." he waited for Zayn to get up, but he didn't.

"Zayn? You comfy there buddy?" Harry chuckled, he didn't know Zayn was trying his best to stop himself from cumming, so when Zayn didn't move, harry picked him up from his armpits, he helped Zayn sit on his lap.

Zayn was still quiet, his breathes were shallow, Harry put his chin on Zayn's right shoulder when Zayn didn't make a move to stand up.

"Whatcha thinking Zay- oh would you look at that?" Harry said when he was how hard Zayn was, there was a little pre-cum on his boxers too.

"yo- i- don't-" he wanted to threaten Harry but his mind was clouded, he couldn't form his word.

"shhh, I got you, you just relax." Harry whispered in his ears, kissing his neck, slowly massaging Zayn's dick over his boxers.

Zayn began to moan grinding his ass on Harry, putting his head on his shoulder.

"please I need t-" Harry put his hand in his boxer, taking Zayn's dick in his hand.

"You want me to make you cum? Answer me." Harry stated, slowly stroking Zayn up and down, teasing his tip.

"yes, oh god plea-"

"Are you gonna be a good boy?" he quickened his movement "are you gonna listen to me?" Harry was going on his full speed now, he knew Zayn was close.

"I m gonna-" Harry stopped "wh- I- I was close!"

"You didn't answer me." Harry moved his hand again.

"I'll listen to you, i-i- I'll s-study hard." Harry was going fast again.

"now that's a good boy." he kept his peace not so fast that he cums soon not that slow that makes him cry.

"I'm gonna cum Harry." he whimpered, his body shaking, toes curling.

"come on." last two storks, and Zayn came so hard, his head on Harry's shoulder, taking deep breathes trying to calm his heartbeats.

Zayn took some tissues and cleaned himself up, ignoring Harry altogether.

"I think the time is up, you can go now." he was back to his bad-boy character.

"heh, ok see ya." Harry was disappointed, but not surprised.

"and Harry if I find out you talked about this with anyone I'll make your life a living hell," he came too close to Harry to make sure he understands.

"goodbye Zayn." and with that Harry left, he regretted showing Zayn his other side, and Zayn? He was worried Harry would destroy his image.
