Work Text:
Reigen sighed heavily for what felt like the hundredth time since he had come in to work after school. Things had been as boring as they had been the previous day, with no clients coming in aside from a handful of pre-scheduled appointments.
And his shisho wouldn’t help cure his boredom either.
It had already been three hours since the last client came in, not too long after he had arrived. Reigen had also finished working on all his homework, leaving him with nothing to focus on. Even cleaning-wise, there wasn’t anything left to do since he had already done that the previous day. All there was to do really was paperwork, and Mob wouldn’t allow him to touch any of it even if he asked to help.
After a while, he ended up standing up from the couch before making his way to his shisho’s desk. He wasted no time in pushing the chair away from it before straddling the older man. This earned him a sigh, Mob simply leaning back into the chair as he looked up at him. “Arataka, I have work I need to finish,” he simply stated.
“But I’m bored,” the young man argued back, leaning in closer to him after wrapping his arms around his neck. “No one is coming, and you’ve been filling out paperwork for hours now,” he continued. “Take a break with me,” he suggested instead with a grin, rolling his hips a little.
Strong hands suddenly grabbed onto his hips, keeping him from moving that way anymore. This made him grin even more. He knew that this could and would get his shisho going. He was a bored and horny teenager, this was an easy option to keep him occupied and happy. Plus, he loved seeing how far he could push the man before he snapped.
“Arataka…” the man warned lowly, hands holding even more tightly when Reigen still tried moving through his grip. If he had some wiggle room before, now he felt completely trapped and unable to move.
“But shisho,” Reigen whined, putting on his best puppy eyes. “I’m bored, and you are not giving me any attention,” he added, letting a hand card through the man’s hair, nail gently scratching his scalp. He smiled when Mob leaned into the touch, eyes closing a little.
“It’s still office hours,” Mob replied, looking up at him again after a moment.
“But there’s barely one hour left, no one will come,” Reigen pointed out. “Come on, shisho~~”
Afterwards, he waited, fingers still gently scratching the man’s scalp. He felt like he was winning when the grip loosened enough for him to roll his hips once again, leaning in closer to the older man. He could see the way the man was thinking about it.
Reigen’s grin grew wider when he heard the familiar sound of the door locking. “Don’t be too noisy,” he was simply warned.
At this, the teenager decided not to hold back, kissing the older man as he started grinding against him more properly. Mob wouldn’t allow much with him yet, but he knew that making out and touching were all right. This meant Reigen would get as much of what was allowed as possible.
He also felt very satisfied that his actions weren’t leaving the man unbothered. He could feel the tent growing in Mob’s pants, mirroring his own. Another way he knew he was doing well was the hold on his hips being nearly bruising, something the man seemed to do without thinking. Although this time it wasn’t to keep him from moving, but to help him do so.
But soon, simply grinding through their clothes wasn’t enough for him. Sure, it felt good, but Reigen wished they could be a little closer. With their pants on like this, there was just not enough friction for him. It had him whining in need, pushing down more strongly in an attempt to get more.
“Shisho,” he moaned against the man’s lips, hands slowly sliding down his chest as he tried to reach for his belt. His skilled little fingers worked it open in no time, a hand teasing the man through his slack. This had him smile against his lips this time, hearing the way his touch made Mob groan.
He barely received a warning when he opened the front of his pants, quickly doing the same for himself. It seemed like Mob also wanted more, seeing how he wasn’t stopping him as he would normally try. Or at least, give his best half-assed attempt at stopping him, just to keep the pretence.
Reigen bit his lips to quiet himself down when he finally started pushing against his shisho again, this time, with a thinner fabric being their last barrier. Maybe if he were patient enough, he could convince Mob to let them go bare for once.
But for now, he kept grinding back against his shisho, the man pushing his hips up to meet him as best as he could. Heat was pooling low in his stomach, accompanied by butterflies, as the man called his name quietly as he went to kiss his neck. He always loved having his shisho’s mouth all over him like this, even better when he would leave accidental marks behind.
“Shisho, please, I need more,” Reigen whined after a while. It wasn’t quite true, he could cum right here and then, actually, feeling on the edge already. And from the shift in the air around them, he knew it was the same for Mob. It would be easy to finish like this and soil their underwear once again.
But he wanted more and wanted to test and see if he could push past another line.
He shivered when Mob exhaled close to his ear, a hand running down his thigh slowly, coming dangerously closer to where they were touching. He held his breath a little as he waited, wondering if the man wanted to take it further, too, for once.
“Fuck,” he moaned when Mob’s large hand took care of pulling them both out of their respective underwear. He couldn’t help the breathy chuckle that escaped him when the man called him out for his language, teeth grazing his skin in warning. But it just felt so good he couldn’t care less about his language.
It felt so good to finally be able to grind directly against his lover, the feel of skin against skin even better than he thought it would be. He bit his lip as he looked down, bringing one of his hands down to help Mob hold them together. Not that he needed it really, but he loved the sight of them together. Plus, the added pressure he gave sure felt good.
The poor office chair was now creaking under them as Reigen’s movement became more frantic, trying to get over the edge more properly now. He had started kissing his shisho again in an attempt to stay quiet, whining against him.
His thighs spasmed against Mob’s legs as he suddenly came, the movement of his hips choppy as he rode the high, stopping only once it felt too much. He knew Mob wasn’t very far behind, the man groaning against his lips as he did, fist pumping them both as he rode his own climax.
Reigen leaned closer as he slowly came down from his high, nuzzling against the crook of Mob’s neck as the older man carefully hugged him to his chest. They had likely made a mess of their shirts, but right now he couldn’t care less. He just wanted to melt into the man and become one with him.
This sure had been better than dying of boredom while waiting for the office to close. He had even managed to go a little farther than usual, which he was really happy about. This was a newly opened door now, something they could go back to later on. It made him wonder if he could keep pushing it a little bit…
“Shisho, can I come to your place tonight?” Reigen asked quietly against his neck, lips leaving a little kiss against the sensitive skin there. He waited a moment, already expecting the rejection, like always.
“Hmm,” Mob hummed as a reply, accepting the offer and making Reigen smile with joy. Maybe tonight would get even more interesting.
