“Good Boy”

Summary: Being in Veterinarian school has consumed all of Yoosung’s time. Feeling lonely, you hatch a plan to combine both school work and play by implementing a “reward and punishment system”...and the results are better than expected.

Going to school to become a veterinarian was not an easy task.

Upper-level courses, clinicals, job hunting…Yoosung had a full plate with his schooling, one that would be difficult to balance for most. Add to that RFA duties, and he was constantly walking a tightrope, barely hanging onto his GPA and his future. Most days he returned to your shared apartment exhausted, the dark circles under his eyes prominent, and would only spend a little time with you while eating before he had to go and work on assignments. Weekends were also spent mostly on studying and prepping for the upcoming week, meaning dates and the like were off the table.

This, of course, put a little strain on your relationship at times- because while you were happy he was pursuing his dream and satisfied with his life, you couldn’t help but feel a little lonely with the way things were currently.

However, you were intent upon making this work; you loved Yoosung and did not want your relationship to fizzle out over something like this. This meant you had to figure out a way to give you both some more quality time together while also not taking away time from his schooling.

This stumped you for a while. You couldn’t add time to your day, meaning you would have to have a trade off of time at some point, right? But that’s not what you wanted…so ideally, you would have to combine the two- quality time and studying- but how?

The answer to your problem came in the form of a BDSM website your friend recommended.

You had been aware of Yoosung’s inclinations for quite awhile (even if he was still pretty oblivious) and had turned to your close friends to help you gather resources on the topic so that you could explore it both sexily and safely. The website in particular that provided your eureka moment talked about different ways of rewarding good “behavior” of the submissive.

It was while reading that rewards could work in the bedroom, that it clicked: the best way to combine school and quality time would be to reward Yoosung for and while studying. Hell, it might even give Yoosung a better incentive to study hard…

It was genius!

You began to set your plan in motion, gathering the necessary tools and materials. You considered telling Yoosung first but decided upon surprising him instead. As excited as you were, you had everything set and ready to go within a week.

It was perfect timing, too- Yoosung had an exam coming up the following Monday, meaning he would be studying like crazy and stressing himself out. When Friday finally arrived, you implemented step two of the plan when he arrived home.

“I’m home, MC,” he said as he kissed your cheek- something he did every time he arrived home. “I’m going to eat really quickly then head to the bedroom to study. I have a test on Monday for Biochemistry, and the professor in that class is super difficult!”

You smiled at the whining edge in his tone. As he made his way to the kitchen, you followed. “Dr.Eoh, yeah? You’ve mentioned him before.” You watched as his shoulders perked up upon hearing you mention the professor by name.

“You remember! I always knew you had a good memory- like how you remember all the RFA member’s birthdays and important dates and stuff,” he continued to babble while heating up the pasta you had made earlier. “You have, like, Jaehee level memory skills. It’s so cool!”

“You exaggerate, Yoosung.” Go time, you thought. “But if you think my memory is so great, why don’t I help you study for your exam?”

Yoosung spun around, the pasta in the microwave momentarily forgotten. His eyes were bright, earlier fatigue forgotten. “Seriously?! You would help me like that?”

“Yes, seriously. I was reading about some…innovative techniques to help with studying just earlier and would love to show them to you.” Not technically a lie.

“I would love to learn them, then! We get to spend time together, too!”

The microwave beeped. You smirked, pleased that the plan was unfolding so smoothly.

“Great! I’ll show you after you eat. You’ll need your energy.”

You suppressed the urge to wink.

~~~

“Uh, MC?”

“Yes?”

“I thought you were going to help me with studying; why are you tying my hands? And why am I, um, naked?”

You finished double knotting the scarf that currently was binding Yoosung’s hands tightly together behind his back and moved to stand in front of him. He was a sight to see- stripped down to his boxers and kneeling in front of you, hands useless and face flushed as red as a strawberry. He wasn’t looking at you.

“You are so cute, Yoosung,” you couldn’t help but coo, reaching out to grab his chin and make him face you. His eyes met yours briefly, before fixating upon the ground again as his face darkened even more. “No need to be embarrassed. This is how I’m going to help you study- with rewards and punishments as your motivator.”

“P-punishments?!” he squeaked. Your thumb ran along his bottom lip lightly, and you felt him shiver.

“For every question you get wrong, you will receive discipline for after. If you get most of them right, I will reward you for it. That seems rather fair, doesn’t it?”

“I mean, I guess…But what will the p-punishment,” he stumbled over the word once more, “be if I get a question wrong?”

You smiled, not unkindly but filled with mischievousness. “Well, I don’t want to ruin the surprise, but I’ll give you a hint: how are naughty boys usually punished?”

You felt him shudder under your hands as he realized the meaning behind your words. His blush had now spread to his chest, staining his shoulders and collarbones pink. Adorable.

“Now let’s get this started.” You grabbed his stack of note cards that he had filled with words, definitions, and practice questions, and began with the top one.

The stack of cards was thick, but it seemed that within an hour you had gone through all of them. You were always impressed by his dedication and fervor with which he applied to his schoolwork and education, and it showed with how easily he was able to answer most of the questions; many he responded to without any hesitancy at all.

However, despite that, he was not perfect and had stumbled through a few. Overall, he had only missed five questions total (you had kept tally), and you had set those cards aside from the stack for his punishment.

After all, what was the point is he didn’t learn anything with this study session? Or at least, that’s what you told yourself.

“You did very well, Yoosung.” He twitched at your praise, though limited by his restraints. “You definitely deserve a reward, but only after we review the questions you missed, and you receive your punishment for missing them.”

“Okay…” he said, seemingly resigned to his fate, but you knew his reluctance wouldn’t last long. You moved to sit beside his kneeling form. Setting the five notecards down, you manhandled him till he was laying across your lap, wiggling uselessly as he tried to find his balance without the use of his arms. In this position, his ass was fully exposed and allowed ample room for his punishment.

You pulled down his boxers, leaving his butt bare to the cool air and your gaze. He yelped.

“For your safety, Yoosung, we are going to have a couple of safe words, okay?”

“O-okay.” He wiggled some more, no doubt feeling vulnerable with his ass exposed as it was.

“’Yellow’ means slow down, and ‘red’ means full stop. I will only stop if you say ‘yellow’ or ‘red’, not if you say ‘no,’ ‘don’t,’ or ‘stop.’ Got it?”

“G-got it.”

“Good boy.” You received full-body shiver in response. “First, your punishment.”

With no warning, you brought your hand down on Yoosung’s ass, the resounding smack echoing in the room. He cried out at the suddenness and friction. You watched as a pink handprint appeared upon his skin. It was your time to shiver as excitement began to bubble in your gut.

You brought your hand down again on the exact same spot, but this time harder. Yoosung let out a gasp. You didn’t give him a break and spanked him again, exhilarating in the warmth and slight sting you felt on your hand.

“Ah, it hurtsss,” he whined, dragging out the last syllable. You rubbed the inflamed skin on his ass gently, even as you felt satisfaction upon seeing the darkening handprint.

“Be a good boy and bear with it. Just a little more,” you said, soothingly. It seemed to work as he nodded his head and went limp across your lap.

This time when your hand met his warming skin, he let out a whimper and jolted in your lap, wiggling and tensing again. You ran your hand down his back until he stilled and relaxed, and then once again without warning, your hand met his behind, even harder the previous times. You knew that one had to hurt.

“Are we done?” he gasped, voice thick. He turned to look over his shoulder at you and his cheeks were marked by tears, eyes shining with many still unshed. The excitement in your gut doubled.

“Almost. Now we have to review the questions you missed. If you miss them again, I spank you again.” You made sure to keep your voice cool even as heat churned in your chest and stomach. You picked up the notecards. “Yoosung, what is the optimum pH of pepsin?

“Uh, I d-don’t know.”

You ran your hand lightly over the warm welt on his behind, as both a reassurance and a warning. “C’mon now- think.”

“Oh, um, two?”

“Correct. Next one: The function of a protein is primarily determined by?” “Its, um, spatial confirmation,” he answered, this time with more confidence. You nodded though he couldn’t see you.

“Yes. Amino Acids in a protein are joined by?”

“Peptide bonds.”

“What is the primary function of the Citric Acid Cycle?”

“To facilitate aerobic cellular energy production.”

“Exactly. Now, here’s the very last one: What is ATP?”

“A purine base and sugar bound by three phosphates.” You sucked in a breath.

“I’m sorry but that is not the answer I’m looking for.” You brought your hand down on the cheek that had yet to be spanked, the pure white skin instantly beginning to mirror the other reddened one.

“B-but that’s right!” Yoosung tried to sit up, but you forced him back down across your lap.

“Yes, but it’s not the correct answer. Try again.”

“I don’t know! A cellular energy transfer medium?”

“No.” You hit him twice this time in quick succession. He began to struggle, so you spanked him a third time, harder than the other two.

“Stop being rowdy, or I’ll spank you again. Hard.”

“But I’m right! That’s right!” He continued to move, ass wiggling in the air as he tried to sit up without the use of his hands. You smacked the reddened cheek again, and then again on the other side for good measure. He finally settled, whimpering.

“But only partially, you aren’t saying the entire answer. Try again.”

“F-fine! It’s also a source of biological electrons! Is that it?”

“Yes, it was all three. Remember that.” You stroked gently over the welts you had left on his behind. He was going to have a hard time sitting later. “Did you learn your lesson?”

“Yes, I did! Now, please, stop hitting me; I feel…weird.” You paused.

“What do you mean ‘weird’?”

He looked over his shoulder once more, face flushed and tear stained. He looked like he had been seriously messed up by someone; he was pitifully cute and vulnerable.

“I mean, like…my dick hurts,” he whined, wiggling his hips, and it was just then you noticed the hard length pressed against your thigh.

You fought back the urge to giggle, pleased. “Don’t worry; it’s time for your reward anyway. I’ll take good care of you.”

You maneuvered him so he was once again kneeling, this time in front of you. In this position, the bulge in his boxers was obvious.

“I thought you said that the spanking hurt,” you teased. “But this part seems to have enjoyed it.” You reached out, lightly tracing the outline of his cock. Yoosung gasped, jolting at the sudden stimulation that still wasn’t enough to provide any relief.

Deciding that you had teased him enough- after all, this was supposed to be his reward-, you pulled down his boxers to mid-thigh, freeing his leaking cock. The tip was slick with precum, and you rubbed your hand over the weeping slit in order to use it as lubricant. Yoosung moaned.

“M-more, please,” he choked out, shivering at the sensations. “I n-need m-more.”

You obliged, grasping his length firmly in your hand and allowing the precum you had on your palm to ease the slide as you set a brisk pace rubbing his cock.

“You’re such a good boy, Yoosung, you know that right? You did such a good job tonight. I’m so proud of you.”

“I’m a g-good boy?” he gasped. You nodded, thumbing the tip of his cock.

“You sure are,” you cooed. “You’re such a good boy. Do you like my hand on you like this?”

“Y-yes, it feels I s-so good.” He moaned again, shaking. “F-faster, h-harder, please, please, please.”

Since he asked so nicely, you did so, tightening your grip on his cock and jerking faster. Obscene sounds filled the room, but you were preoccupied with watching Yoosung fall apart under your ministrations to notice.

He was such a pretty thing when he was like this- skin a blotchy red, hair flat with sweat, eyes bright with pleasure and his early tears, body continuously wracked with shivers, hips thrusting uselessly, and mouth open as he sighed, moaned, and gasped in pleasure. You moved your hand faster.

“A-ah, no, stop, I’m going to c-cum if you move your hand like that…”

You smiled at him, refusing to stop. “Then cum for me like a good boy.”

Just like that, he came undone under your touch, tensing up, eyes squinting shut and thrusts becoming erratic as his orgasm hit like a train. He groaned sweetly as his cum covered your hand and lap. A few moments later, he went limp, falling forward onto you.

You reached behind him and untied his hands. “Let’s get you cleaned up.”

A week passed. It was in the middle of the afternoon when you got the text:

Got a 100 on my Biochemistry test! Help me study for the next one, please? 🥺
