Only twenty minutes had passed since you convinced Tsukishima to help you study for the upcoming exam and you were already regretting it. The fact that you were his girlfriend didn't stop him from being as ruthless as ever when it came down to grades.

"Wrong again," he said with an exasperated sigh.

You groaned and leaned back, already tired of these math problems that he so mercilessly continued to throw at you. Math was never a strong subject of yours and he knew it.

"Could you explain again how to solve it?" you asked, already frustrated by the confusing jumble of numbers before you.

"I've already explained it three times. I won't be there on the day of the exam to show you how it's done."

You pouted and wrapped your arms around his neck, bringing your face only inches away from his. "Please, Tsukki?"

He rolled his eyes as he carefully removed your arms from his body. "Fine, but you better pay attention this time."

Tsukishima began explaining the first steps to solving the problem and it was obvious how absorbed he was with the equation at hand. Without meaning to, your focus was redirected to staring at him and smiling at how his brown eyes were locked on the paper. You were so absorbed in watching him that you didn't even notice that he finished speaking until he snapped his fingers in front of your face.

"What?" you asked quickly, surprised by the sudden trip back to reality.

"Were you even paying attention, [name]?"

You obviously weren't, but you knew it would be best to just lie at this point. "Yes, of course."

He pushed the paper over to you, giving you your cue to try the problem once more. Your mind went blank when your eyes landed on it, not remembering a single thing Tsukishima had said just moments before. A couple of minutes passed by until you finally finished the problem, knowing full well that there was absolutely no chance that it was correct.

Tsukishima, who was obviously frustrated at this point, pinched the bridge of his nose and inhaled sharply. "Is it really that hard to pay attention?"

"I'm sorry," you whined as you rubbed your temples. "It would be a lot easier to focus if there was something to motivate me, you know?"

"Motivation, huh?"

He thought about that for a few moments and for whatever reason, you felt your body tense in fear for whatever idea he would have it mind.

"Strip."

"W-what?" You must've heard him wrong. There was no way he could've possibly said what you thought you heard-

"Strip," he repeated again. "For every question you get wrong, you'll remove one article of clothing. That is, unless, you don't want my help anymore."

You thought about it for a moment. It was an absolutely crazy proposition but then again, you did ask for something to motivate you and this did fit the bill as embarrassing as it was. As long as you got the next few questions right, you wouldn't have anything to fear.

"Fine... But for every question I get right, you have to strip too."

He smirked, obviously more than okay with this idea. If he was going to sit here and try to get you to learn something, he might as well enjoy himself while doing so. He raised an eyebrow at you, signaling what needed to be done after getting this most recent question wrong. Making a face at your ever-so-cocky boyfriend, you removed one of your socks only for him to click his tongue.

"Both socks count as one article of clothing," he told you. You scoffed at the statement but listened nevertheless. You removed your other sock and threw it beside you.

He motioned his head towards the paper which contained the next few problems that you would need to solve. You tried to focus on the next equation at hand but similar to before, the layout of the numbers didn't even seem to make sense to you. Either way, you knew you had to at least attempt to solve it.

At first, you thought things were going okay until the answer somehow ended being some long, repeating decimal. It was only then that you started to wrack your brain for which piece of clothing you'd want to take off next if Tsukishima was really going through with this whole 'motivational' studying session.

"Honestly, [name]," he said in an annoyed tone despite the smirk that was threatening to make an appearance on his face. "You're starting to make me think that you want to strip for me."

With a pink tinge present on your cheeks, you quickly slid off the shorts you wore before sitting back down. You didn't want to give Tsukishima the opportunity to make any more comments than necessary.

This was how the rest of the studying session progressed for the next thirty minutes. Once you were finally on the last question, you were already completely bare naked while Tsukishima was down to his boxers. Unlike him, who didn't seem phased at all by how exposed he was in front of you, a blush had made its permanent residence across your cheeks and you did everything you could to cover your body as much as allowed. You were just surprised that you actually managed to solve enough problems correctly to get him down to just one article of clothing. It was an unusual type of motivation, but it was most certainly effective.

There was only one question left and although you had no more clothes to shed, you didn't want to imagine what punishment Tsukishima would come up with if you failed to answer this one correctly. While solving it, you tried your best to remember all the advice he'd given you when explaining how to solve the equations earlier. Despite the difficulty of the problem, you actually managed to answer it correctly, to your surprise.

"There!" you exclaimed, proud that you managed to answer the last one correctly. "Your turn to strip!"

Smirking, he slowly slid down his boxers, leaving him completely naked like you. If anything, seeing him in his full glory only made your blush deepen even further. You felt the familiar heat in between your legs and yearned to do far more than just study.

"Don't get too excited. Getting four out of eight correct isn't passing," he teased.

"F-fine. Then I guess let's work on more problems."

You tried to reach for your shirt, but he quickly stopped you. He pushed you back so you were lying flat on the ground while he hovered over you with his hands pinning your own to the ground. Your eyes widened at his sudden actions, but you did nothing to deter him from doing more.

"We can study later," he whispered as he grazed his teeth against your nipple. "I have something else in mind for now."
