05:45pm…

Y/n was far too distracted to care about her surroundings as she yelled at the arcade game in front of her, furiously tapping away at the controls while arguing with her friend about how he was going to lose this one, much too engrossed to notice the figure approaching her from behind.

Seungmin's eyes narrowed in on the short shorts his girlfriend's perky ass was adorning tightly to beat the summer heat, hips swaying side to side as she violently hit at the controls to win, tits jiggling in the tight tank top whenever she moved. The younger male shook his head at the sight, sighing to himself.

"H- HEY! HEY! WHO THE FUCK- LET GO!" The older bellowed when Seungmin pulled her back and out of the arcade station by her nape too quick for anyone to even notice. "HEY! THAT IS NOT COOL, DUDE!" Y/n grunted and pushed at his chest when he pressed her back flat against the concrete wall of the alley next to the station, almost succeeding since both were the same height. "I WAS ABOUT TO WIN!"

Seungmin didn't respond to her bratty antics and quietly fished out a piece of paper before grabbing one of her hands that were surprisingly smaller as compared to his regardless of the fact that they were the same height, roughly thrusting it in her hand before flipping her on her stomach against a closed dumpster can after manhandling her to it.

"Dude!" Y/n groaned as she looked around in panic. "We have to be secretive about this! You can't just drag me like this in an alley! What will my friends think?! That I am dating a sophomore while being in my senior year?!" He rolled his eyes at her never stopping mouth. "Just how many times-" her words faded into a gasp when he harshly tugged the older's shorts off along her underwear in one go.

"Read."

It wasn't like Seungmin was a guy of too many words anyways but the tone that he used made it clear to Y/n that she was in deep today.

"W- What is it?" She nervously laughed, glancing down at the paper as she mentally recalled everything wrong she'd done since her last punishment.

"I said… read" Y/n's knees buckled in defense when a harsh spank landed on one of her ass cheeks, the throb coming almost right after.

"W- Where did you get this?" Shaking his head, the male dropped his own bag on the floor, pulling his wooden ruler out.

"You're not helping anyone here" Seungmin sternly responded, holding her lower back firmly against the plastic can to restrict movement when she yelped and tried to move away from the spanks he was landing now. "Especially not yourself."

"Fine! Fine! I am sorry! Hold on!" Y/n cried out, whining as she hurriedly started ready. "Y/n, senior year, section C, physics- OWWW!" One of her feet kicked the floor as she groaned when the male didn't stop, spanking her with every word she said. "12 o- out of 100" she was softly crying at this point, face hot in embarrassment.

"What was it that you did wrong?"

The girl kept whining with each hit miserably, closing her eyes each time before the spank even landed, the quiet alley providing her perfect sound of the ruler whipping through the air each time. "I- I didn't study and l- lied to my boyfriend about it" a soft whimper escaped her as she continued. "I- I wasted my time on a- arcades and c- comics even when he had warned me about f- failing- AAHH!"

"And what are you now?"

"A sorry little dummmmmmyy~" Y/n buried her face in the paper as she whined out, legs shaking slightly as she felt the air nip at her sex. "I am sorry s- sir! I won't do it a- again! I promise! Please, sir!"

Seungmin only stopped when he was satisfied, handing her the ruler as he caressed her burning ass soothingly, watching her as she carefully examined the wooden object. It was a thing to him. Whenever he punished her, he'd hand her the object he'd used after, making her look at it and think about her actions as well as the alternative way she would have gone and avoided the punishment altogether.

"Come on up" gently pulling her back up, the male turned her around to face him only to find her biting her lip while staring at the ground, cheeks red in embarrasment. "I need to figure out new punishments for you" pushing her on her burning ass against the dumpster, Seungmin sat her on it, hands gently nudging her thighs apart.

"Because it is not a punishment if it is making you wet, right?" Y/n's mouth fell open as her back arched in response to the male's fingers making contact with the flesh of her dripping cunt. "Tsk. I'd be so ashamed of myself if I were you, Y/n-ah" he softly slapped her with the back of his free hand, other slowly teasing her folds. "Getting this wet to being bent over a dumpster and spanked with a ruler like a little kid. Tsk. Are you sure you're the older one here?"

"S- Sorry, sir! I am sorry~" the girl shuddered, droplets of sweat running down her forehead as she whimpered at the knots forming in her stomach. "You're j- just soooo goooood~" a frustrated cry escaped her when he continued to tease her torturously slow.

But she knew better than to whine about it. Knowing Seungmin, he'd chastise her for at least a week for being impatient.

"If I were to finger fuck you right now…" Y/n's eyes snapped open in excitement, hopefully watching his cold expression. "Will you tell me when you're close?"

"Y- Yes, yes sir! Yes, please sir! Please!" The girl softly pouted needly, rolling her eyes to the back of her head and inaudibly thanking Seungmin when he picked up pace, slowly nearing her leaking entrance before pushing in with a plop, making Y/n arch her back as she grabbed the edge of the dumpster lid for support.

"I don't get why you even bother with trying to keep up this big bad image of yourself when you love to get put in your place by me, a younger guy, so much that you don't even care if it's a shady alley as I make you sit on top of a dumpster against your burning ass," he was always relentless with his words and degradation. "While you have no choice but to take what I give you while thanking me for it." Her pussy clenched around his finger, signalling that he was doing a good job.

"Ah! Sir! Sir! Please, I am close, sir! Please, sir!" Y/n cried out when he started toying with her clit at the same time, slapping her cheek with the back of his hand again.

Seungmin snickered when the girl cried out in despair upon the loss of all stimulation when he suddenly pulled his fingers out of her, enjoying the devastated expression on her face.

"What?"

"SIR…!" Hot tears streamed down her cheeks as she protestingly looked up at him, one fist balled.

"Tsk, did you forget?" Shoving his cum coated fingers in her mouth without a second thought, Seungmin grinned as he soft slapped her again. "This is a punishment." Her nostrils flared for air as she whined loudly around his fingers, pouting a little. "Only good girls get rewards, remember? Not disobedient little ungrateful brats."

Pulling out his fingers out of her mouth with a loud plop when they were clean, Seungmin teasingly hit one of her cheeks with the back of his hand again, making her whimper in respone. "And which one are you?"

Y/n's eyes and head lowered. "A disobedient little ungrateful brat, sir."

The male hummed in satisfaction as he nodded, cupping one of her cheeks and making her look up at him before caressing her lips with the pad of his thumb. "Now here is what's going to happen. You will go in there and get your bag along with some lemonade for the both of us and then we will go home, yes?"

"Yes, sir" after carefully helping her down on her feet, Seungmin fixed Y/n's clothes, taking off his flannel that he wore atop a t-shirt before wrapping it around her exposed legs, giving her the money for the beverages because he liked to pay for the both of them, waiting outside the arcade in a corner so he wasn't too noticeable, respecting his girlfriend's wish for the relationship to stay private until she felt comfortable.

"And don't you dare skip school without permission ever again" Y/n whimpered at his stern tone before curling in his arm, burying her face in his shoulder after she had handed him his drink along with her bag that he insisted to carry, intertwining her fingers with his as she sipped on her drink. "I got so worried when I couldn't find you for the whole day after we entered together this morning."

"Sorry, sir. I won't do it againnn~" the couple slowly walked to Seungmin's house, enjoying the sunset as they laughed about how they stank, the male deciding they needed a shower the minute they got home.

And they took that shower, Seungmin cleaning the both of them thoroughly to get rid of any and all germs before fucking Y/n numb after she promised she'd always obey him from now on, both of them already knowing she was bound to stumble again.

Neither of them were complaining, though.
