Work Text:
Joshua's tutoring services were cheaper than a cram school—better, too, he liked to say—and after a probationary period wherein he'd charmed Neku's mom, he was officially hired to teach Neku until his high school exams.
Joshua had always done something to Neku, from the obnoxious way he corrected his wrong answers to the way he watched Neku work instead of paying attention to the ink on the page. A part of Neku wanted to impress him, if only to force Joshua to give a begrudging 'well done,' so Neku could feel like he'd finally won one over on him.
What he actually got was a sly smile and "Very good, Neku," in a low, coy voice that haunted his dreams.
Maybe it was obvious from the start. When Neku presented his improved test scores and Joshua offered a special reward, they both knew what he meant. Neku had come embarrassingly fast in his fist, and Joshua giggled, saying, "This will be our little secret," and, "I don't accept refunds."
Neku liked to think that he didn't look forward to Joshua coming by. That his pulse didn't skyrocket when he said they were ahead of his lesson plan this week, and they could spend the rest of the session however Neku wanted. "You can teach things ahead of the class," Neku grumbled. Joshua gleefully whispered about all sorts of things he could teach him ahead of his class, until Neku smacked him away and specified a subject he couldn't pervert, face burning.
This was the first time they were set to study in the library of Joshua's university, or anywhere aside from Neku's place. Normally Joshua just showed up on the doorstep when he was scheduled—or in the living room if Neku was late getting home, the plant where Mom insisted on leaving a spare key looking freshly disturbed. A part of Neku was relieved that they would be studying somewhere public this time, so Joshua would have to be on his best behavior for once. At least, that was what Neku thought until he saw the little private room Joshua booked for their session.
"Common practice, so we won't disturb anyone else in the library," Joshua said upon seeing his suspicious look, but it was clear that he was the one who didn't want to be disturbed.
"Is sex all you think about?" Neku grumbled, skin prickling as Joshua slid his chair right beside his at the table.
Joshua leaned in, the long locks of his hair brushing against Neku's shoulder. Neku forced down the urge to shiver. "Unlike someone here, I have plenty of room to think about multiple subjects at once."
Sometimes Neku wanted to call him out on comparing himself so readily to a 15 year old, but that would mean admitting that he was inferior to Joshua in some way. Even if Neku logically recognized the gap, the part that knew Joshua would find a way to mock him refused to ever bring attention to it.
Instead, Neku told him to shut up, that he was paying Joshua to help him prepare for his exams so he should do that. It was firm enough for Joshua to understand that Neku didn't want him to screw around here, yet that slender hand found itself between his legs anyway. Joshua cleverly kept to his end of the bargain—easy for him to go on teaching like usual when Neku was the one being tormented. Neku tried to work through it, as Joshua kept squeezing at the little bulge in his pants until it swelled and he could barely answer straight.
"Come now, Neku. I only booked this room until six. If you don't finish your review in time..." Neku's gut clenched as he glanced at the clock. Just ten minutes left.
"I hate you so much," Neku choked out, more angry at himself for falling to Joshua's pace than anything else. He could have slapped Joshua's hands away, could have left and taken care of things in the restroom, but instead he was glued to his seat, waiting for the touch of cool fingers around his bare cock.
"I know, Neku," Joshua said, like he was coaxing a child. His breath brushed Neku's ear just as delicately as his fingertips ran over the seam of his crotch. He should have worn a belt today—that way Joshua might have at least had to use two hands, extending a fraction of effort more than the nonchalant way he opened his pants.
Neku turned his face into his hand, biting at the knuckles as a shaky sigh escaped through his nose. The world went into static when Joshua gripped at him, no need for spit or lube to ease the friction when Neku's cock was already oozing from the tip. Joshua's shoulder was pressed against his and when Neku tried to breathe in, it was Joshua there, too, warm and spicy.
He could hear the grin in Joshua's voice as he asked, "And what did you say was the answer to number 14?" If Neku could find a way to speak without moaning, he would have told him to piss off. When he didn't answer, Joshua switched to trailing his fingers over his cock instead, the implication that he would only continue if Neku played along as plan as day.
At least when Joshua was light and teasing it was easier to think. "It's... it's C. Asshole." Neku's eyes flickered to the clock again, his heart skipping a beat at the thought of getting caught. He glanced over the questions again, trying to steady himself even when all he wanted to do was enjoy Joshua's hand on his cock. Neku bit down harder to fight off the pleasant sensation with pain and collected the fluttering thoughts before they evaporated from his head all together. "Last one's B, so just-" he cut himself off before he could beg.
The expression on Joshua's face made it seem like he'd heard it anyway. "Hee hee. Very good, Neku." The pace of his stroking rose, and Neku's panting with it. Joshua was watching him idly, teasing at the end of a pen with his teeth in a way that made Neku absently follow along, nipping at his own lips in shoddy substitution.
Just as Joshua rolled it against his tongue, pumping at Neku faster, the pen fell from his fingers. "Oops. Let me get that." Before Neku could even wrap his head around it, Joshua was withdrawing that wonderful touch to dip under the table in search of his damn pen.
"Joshua—" Neku growled, just barely resisting the urge to kick at him while he was down there. The second hand on the clock was ticking by awful fast and he knew Joshua was taking his sweet time to make him sweat.
It would be safer to do it himself, to accept the loss and Joshua's smug little smirk. His hand crept downward to his aching cock, tempted, but then he could hear Joshua in his head, crooning, 'So excited you couldn't wait for me? How cute.' Neku swallowed hard and dropped his hand to the chair. "Hurry up already," Neku said, trying to make it sound less like the nervous plea that it was.
He was an idiot to think Joshua's plan was to stall for time, that he didn't have anything else in mind. Neku froze. Joshua's hands were brushing against his knees, sliding his legs apart so he could get between them. Neku took a gulp of air in preparation, worried that he wouldn't be able to breathe at all when—
"Oh, God," Neku couldn't stop the whimper when he felt Joshua's mouth wrap around his cock. He nearly melted in his seat, the velvet-soft press of Joshua's tongue over his length unbearably perfect. Joshua's body temperature was always cooler than his own, but the inside of his mouth was so hot.
Neku had the brief thought, like lightning, that he was glad Joshua was stuck under the table, that he couldn't witness the awestruck expression he had to be making. He wished the same could be said for the noises he was making, little squeaks and gasps he couldn't hold back. Even the moan stuck in his throat broke free when Joshua's mouth pulled back, sucking hard at the head of his cock. Neku's fingers flew into Joshua's hair, head dropping against the table, mind going blank. He couldn't take anymore. How was he supposed to stand it when Joshua did something like this? Fuck, he was so close.
Knock-knock-knock.
The three raps on the door made Neku practically jump out of his skin.
His heart was in his throat, pounding. Neku squirmed in his seat, pulling hard at Joshua's hair, anything to get him to stop while he could still fight the pressure coiling inside him. "Quit it," he said, voice cracking with desperation, but Joshua didn't. His mouth was sinking down further on him, taking Neku's cock all the way to the base. Neku should have been angry, and he was, but he couldn't find it right away, too overwhelmed by how good it was to be fully encased in that heat.
He bucked into Joshua's mouth, biting down the pathetic sound of his moans, eyes burning with humiliation at the thought of being seen like—this. Neku turned his face from the door, fighting the shudder running down his spine and further as his climax burst through him, exploding into Joshua's mouth.
The door clicked open. Neku's shoulders stiffened, his breath caught.
"Sorry, I didn't realize there was someone still in here." A woman's voice. Neku's throat was sealed shut. What the hell was he supposed to say? She couldn't see anything from there, right? Maybe he could just pretend he'd fallen asleep, or, or—
"My, how the time flies," Joshua said, drawing himself back into his seat. He straightened his hair and flipped the pen he'd purposefully dropped around his fingers with a little laugh. "My pen rolled further down there than I thought. Just give us a moment to clean up and Neku and I will be right out of your hair."
Neku couldn't bear to look her in the eye after what she'd practically walked in on, but he nodded stiffly. Of course Joshua had no such qualms, easily lying with the same mouth he'd used to swallow his cum mere seconds before.
It wasn't until she closed the door behind her that Neku could finally breathe again.
"Relax, Neku," Joshua said, laying a hand against his shoulder. Neku roughly shrugged it off and pulled away, fixing his clothes before shoveling his books back into his backpack. Joshua let out a long sigh, like Neku was being the unreasonable one here. "Come on, everything turned out just fine."
The glare Neku gave him twisted his face so hard the muscles hurt. "If you ever try anything like this again—"
"You'll what?" Joshua smiled with his teeth, a quiet threat. "Come twice as hard next time? Hee hee. I know how much you love it."
Neku's stomach felt tight. Nauseous. At times like this, he wondered if Joshua was right. It made Neku feel so stupid and predictable, like a little toy that Joshua could make dance to his whims no matter how hard he tried to break free. Worse yet was the idea that he couldn't get enough of that, too.
The wicked smile Joshua watched him with was horrible and infuriating and he didn't know if he wanted it to stop. Neku tore his eyes away from it, face hot with anger and embarrassment. "I wish you knew when to shut up."
