"Meet me in the bathroom on the D hall in ten minutes."
That is what the text message said.
He would obey, but why is he going?
"Why?" was the reply.
Siwon quickly took a look around after sending the message to ensure that no one saw him, particularly not Mr. Ryeowook, his nasty, brutish, and short history teacher. He hadn't. Mr. Ryeowook was still facing the board, lecturing diligently about John Locke and his impact on both European and American history.
Siwon’s phone vibrated quite loudly and as soon as he noticed, he coughed to cover it up, and swore in his head for not turning off the vibration.
After he turned his phone on silent, he read the reply, which was: "It's a surprise!"
With quick, constant glances up to the front of the classroom, Siwon typed into a new message, "After Ryeo is done lecturing? 15 minutes?" and slipped the phone back into his pocket.
"John Locke's Essay Concerning Human Understanding, his most famous work, advocates the idea that humans are not born with innate ideas. He thought that the "tabula rasa", or blank slate, was written over time by experiences in one's life. Personally, I must disagree with Locke, and turn in favor of the idea of absolutism. Because humans are not born empty, we are born with the desire to have sex and hurt things, and thus, we should be controlled by one all-powerful ruler with unquestionable power, rather than giving our savage race "liberal rights" like life and liberty! Ugh! Yes, Sungmin?"
"Not to get into an ideological debate, but in the case of an absolutist monarch, wouldn't the monarch also have the same inborn desires you say we all do? Which would mean, in my opinion, that he should not have dominion over the rest of his people in an oppressive hegemony to subdue the desires that you say every human, including him, is born with just because he happens to be in a position to do so."
Siwon quietly laughed along with the rest of the class at Sungmin’s very intelligent observation and overturning of Ryeowook political theory before checking his phone for the next text message.
"If we wait that long, we wont have time for the surprise! 6 minutes!"
"Fine." Siwon texted back.
Mr. Ryeowook scowled and growled without really offering Sungmin a good opposing argument on that point, and continued to teach.
The next four minutes seemed to drag by as Ryeowook wrapped up his lesson on Locke and the rest of the class took notes.
"Alright, class. As a special treat for our Enlightenment chapter, we are going to read a short book…" he paused as the class groaned "...called Candide, by Voltaire, who I will talk a little about as… “Mr. Choi please pass out the paperbacks."
A bit of panic struck Siwon as his name was called because he had not been paying attention.
"What?"
"Please pass out these books, Mr. Choi?" Mr. Ryeowook repeated.
"Oh, actually, could someone else? I need to use the restroom." Siwon said, knowing that he wouldn't be on time for his meeting if he had to pass out books. When Mr. Ryeowook opened his mouth to protest, Siwon went into acting mode. "It's an emergency." he said standing up.
"Well, alright Mr. Choi. Please take the bathroom pass and leave before you make a mess."
Siwon didn't hear anything else distinctively that went on in that classroom. He thought he heard Mr. Ryeowook made Sungmin pass out the books. Regardless, all he cared about was getting to the D hall where he was called.
Siwon was on the opposite side of the school. He sprinted when possible, only walking when someone else was on the same hall as he.
When he finally reached the D hall restroom facilities, he was half out of breath, partially from running, but mostly from anxiety. But, the long ten minute wait was over. Siwon pushed open the door to reveal a long hall of stalls. Standing at the very end of the hall was who he had been expecting, the one who had summoned him.
"You're right on time, Siwonyny," Donghae said with a bit of mystery in his voice, as if he had called "Siwonyny", who was now walking toward him, for a mission.
"Yeah, I'm here. So what's this all about?" Siwon asked.
Donghae looked as if he was about to explode with excitement. Not the usual happy excitement that was seen by all on a daily basis, but a different sort.
"What is that look for?" Siwon asked.
Donghae just smiled mischievously and leaped into the last and biggest stall. Siwon followed, but stopped short when Donghae slammed the door shut behind them, locked it, and proceeded to unbutton Siwon’s pants.
"Umm..." Siwon started, rather calmly for what was happening to him. "...what the hell are you-" Donghae shushed him.
"I'm teaching you, Siwo-puu!" Donghae told Siwon as he slowly pulled down Siwon’s pants and then proceeded to pull down his own.
"Do you know what class I was in just now?" he asked.
"Gym," Siwon said simply, mentally patting himself on the back for remembering Donghae’s schedule.
"Yes, but we are in health this week, and we are in our Sex Ed. unit," Donghae said, grabbing Siwon’s butt cheeks.
Siwon fidgeted a little, since he didn't quite expect the sudden grab.
"I told Mr. Kangin that I was squeamish and that I didn't want to see the video. And I don't, I told the truth about that! But I'm not at all squeamish about that kind of thing."
As soon as Donghae was though speaking, he jerked down Siwon’s boxers and dove down toward Siwon’s manhood, and taking it all in at once.
Siwon made a weird noise. It was a gasp plus a moan, with a side of, "Oh my gosh,". Donghae only smiled and continued sucking Siwon, whose knees were shaking. As Donghae sucked more, Siwon made more noise.
Donghae stopped, and spit out Siwon’s penis, which stayed straight up right where he left it, so he could talk.
"Why'd you stop?" Siwon asked, a little irritated.
"Because, Siwo-patience, this is supposed to be a edumacational! I have to make sure you're learning! Now, what is this?" Donghae questioned, referring the thing he just spit out. Even though he only lightly touching it, Siwon couldn't help but spit on Donghae’s hand. And not with his mouth, either. Donghae giggled and licked it off.
"It's my big penis, crazy bitch. We both already know that."
"Hmm, naughty language doesn't get you any rewards! Next question, what are these?"
Siwon let out the loudest moan he had in a while as he struggled to quickly answer through it, "Testicles!"
"Very good..." Donghae said, as he slowly went back for more. This time, his tongue took its sweet time licking through every single cell between Siwo’s legs, including his testicles. Siwon had been trying to hold back, but he couldn't take it anymore and cried out as loud as he dared Donghae’s name.
Of course Siwon didn't want Donghae to stop, but he did. Perhaps Donghae was done anyway, because he had another question. He stood up.
"Siwonyny, do you know the proper term for the slang word, "coming"?" Donghae asked, without giving Siwon’s a chance to answer. Donghae grabbed Siwon’s butt while pushing it toward him and Donghae also thrusting himself forward. Donghae still had his boxers on, but it didn't matter to Siwon. He was practically in heaven.
"Oh... these are a hinderance, aren't they?" Donghae commented, looking down toward his boxers and also to Siwon’s fat erection. Donghae stepped back to remove the boxers, and threw them behind him. Then he thrust himself back to where he was before so Donghae’s manhood was smashed against Siwon’s.
"That's better," Donghae whispered as he grabbed Siwon’s face and launched forward to make out with him. Siwon caught him around the waist, but moved his hands down south to Donghae’s bare bottom. Donghae wrapped his skinny legs around Siwon’s middle, making sure they were still touching down there, and Siwon backed into a wall. Tongues flew everywhere, not just in each other's mouths, but also all over each other's faces, in each other's ears, and all over each other's necks. Sweat began to run down both of their bodies as they panted in unison.
"Getting closer, Siwo-sexy?" Donghae’s asked to his ear, taking a two second break from eating Siwon’s face.
Siwon took a two second break as well for a big breath and to say, "Very close,"
"Here, let me help," Donghae allowed his half-naked body to slide down Siwon’s until his head was level with Siwon’s throbbing erection. Donghae sucked and blew, in and out, up and down, and all around. Siwon had given up trying to stifle his moans. They were greater than or equal to the passion of Donghea’s sucking. It made Siwon’s rocket shake and quiver before its launch.
"D-n-hae..."
Donghae sped up his process in order to make Siwon come faster. It worked. Not only that, Siwon’s knees buckled five seconds after the Siwo-cream was blasted all over the inside of Donghae’s mouth.
While he didn't like to look vulnerable or weak, he had to rest on the tiled floor next to his pants and boxers for a minute. Siwon’s heart was racing and he had to catch his breath from receiving the best blow job he had gotten in a while.
After swallowing all of what had gotten in, and not around, his mouth, he spoke. "Now, to make sure you are learning," Donghae began, as he was also a little out of breath, "what is this called?" he asked, pointing to a little bit of what Siwon had spilled in Donghae’s mouth.
Siwon answered correctly as Donghae licked the semen off his cheek with his long tongue. Siwon’s reward was a big, open-mouth, tonguey kiss, which he gladly took as Donghae climbed on top of him, allowing their two sausages to touch once more.
"Now, what is the proper term for the slang, "coming"?"
The door to the bathroom opened the second after Siwon answered. Siwon gave Donghae an anxious look, but Donghae stared back into his red eyes with a plan.
"Are you ready to apply what you've learned?" he asked, barely a whisper, as he brought Siwon’s head as close as he possibly could.
Siwon nodded.
"Let us review what we've learned today," Donghae said.
Siwon was not opposed to "reviewing", but he did not want whoever had entered the bathroom to know what they we're doing. He decided to pretend that he was taking a dump. He picked Donghae up and placed him in the corner while he tidied up by hanging their clothes in a place where no one looking under the stall would see. Then he turned back to Donghae, who was already next to him, shirtless, beginning to remove Siwon’s shirt.
"This could get messy," he whispered as he felt up Siwon’s buff, buff body. Siwon shirt with the wolf on the front was hung up with the rest of the clothes. Donghae silently climbed up Siwon’s body like a monkey and secured himself around Siwon’s middle again.
"You ready?" It was silent, but oh so clear, and Siwon nodded again in approval as he sat down on the toilet with Donghae in his lap.
Donghae climbed even higher, with no objections from Siwon, until his crotch was in Siwon’s face. Siwon didn't even need to be told what to do.
Donghae seemed to have a little more control over his noise making. Only twice did he quietly cry out Siwon’s name, and both times were during the flushing of the other person who was also in the bathroom.
The person turned on the sink. Donghae took that chance to say, "Get ready,"
Siwon prepared for Donghae white explosion, which came as soon as Siwon put Donghae back in his mouth. They were trying to be quiet, but they couldn't breathe correctly and be quiet. Thankfully, the guy who came in the bathroom left promptly after drying his hands. As soon as the door shut, Donghae slid down from being wrapped around Siwon’s neck and sat in his wet lap, right on his log. For yet another make out session.
"That was amazing, Siwo-kinky," Donghae said between licks.
"I know. I was there." Siwon’s said back in the manliest way possible.
Neither gay knew how long they were licking and kissing on each other, but when they finally stopped, Donghae asked as seductively as he could, "You ready to end class, or do you want some extra credit?"
"Extra credit never hurt anyone," he said, sliding his hands down to Siwon’s butt and sliding him as close to his crotch as he could.
"We haven't learned about butt sex in class. Your assignment is to enlighten the teacher on this subject."
"That, I can do," One more kiss he gave before he turned Donghae around and stuck himself into Donghae butthole.
"Mmmmm!" Donghae was happy. Siwon couldn't do this correctly sitting down. He and Donghae stood on the floor and Siwon began thrusting into Donghae’s backside.
"MMMMMMMMMM!" Donghae was very pleased with his student. Thankfully, no one else entered the bathroom while they were in there because Donghae was being loud. Especially when Siwo-cream was blasted between his legs again.
"Oh, shit. It's been fifteen minutes?" Siwon finally took a look at his watch, the only article of clothing still left on him.
"Oh, sorry to keep you, Siwo-rin,"
"Oh, no," Siwon started. "It was worth it." He kissed Donghae one more time. "But I've got to get back to class."
Siwon got dressed as quickly as he could and ran out of the restroom, down the hall, and back to the A hall where Mr. Ryeowook class was.
"Sorry it took me so long, Mr. Ryeo," Siwon said, making a pretty big entrance, most likely unnecessarily. Siwon expected Mr. Ryeowook to be angry, or at least question why he was missing for so long. Siwon mind began racing to find a decent and believable excuse. I went to the library? I stopped to talk with a friend? A teacher? I was taking a really big crap?
"Mr. Choi... why is your shirt on backwards?"
Siwon blinked. That was not the question that he expected. Not only that, he was totally unaware that his shirt was, indeed, on backwards.
"You're sweating. And what is that on your face?" Mr. Ryeowook inquired. Siwon slowly reached up to touch his cheek, then the other. Nothing was there.
"Your forehead," Ryeowook corrected.
Siwon felt his forehead, and immediately gasped and his eyes grew wide. Some of Donghae’s cream was still on his forehead. And quite a lot of it. He looked around and the entire class had their eyes on him.
"Do you have an explanation, Mr. Choi?"
"I... uh... doughnut. Yes, doughnut bavarian! I saw my friend and... he had doughnuts....doughnuts. Then she I mean he went a little crazy and threw one at my face, that I caught, and ate, since I know you don't allow food in the classroom."
"And that took fifteen minutes? Why are you sweating?"
"Well... the doughnuts were so damn good, that I wanted more than just that one. My friend challenged me to a race down the hall. I won. I got another doughnut."
The class giggled at this excuse, but Mr. Ryeowook accepted it and asked Siwon to sit back down. Siwon had a copy of Voltaire's Candide on his desk when he returned. He cleaned off his forehead, looked around to make sure no one was watching, and licked his fingers clean.
Out of impulse, Siwon checked his phone and was pleased to find one new text message.
"Mr. Donghae gives you an A+. He would also like to know if you're interested in taking his AP class later tonight. ;)"
After making sure it was safe to text, he replied.
"I'll be over at 8."
