Work Text:
The muffled moans and slithering sounds can be heard from inside the last bathroom stall and then there's Aether standing with a tomato face peeking from the little gap between the door and the wall, now he finally knows why Childe wanted to be a gluestick.
~~
Some time before.
"Aetherrr, do you think a gluestick can be used as a sextoy?" Childe asked randomely while remembering the porn he saw last night as he layed his head on the lunch table, munching on his old apple slices.
Aether choked on his ramen and Xiao shreeked.
"You...! How are you asking such a shameless question!?"
"Just answer me!"
Aether coughed and shifted uncomfortably.
"I am not gonna answer that!"
"Aether, do you want me to end him?"
"No, Xiao sit quielty, I don't want you to be responsible for another genocide."
As the bell rang, the boys returned to their class and greeted their Human Sciences teacher, Miss Guizhong. Halfway into the lesson, Childe found himself being so bored he that he'd rather annoy Xiao, but he doesn't have a death wish, so like any other student, he excuses himself to the bathroom, thinking he can talk a stroll or buy something from the cafetaria in the way.
After checking all the bathroom stalls, he cursed when all were locked, as he reached towards the end, one door was unlocked and ajar. Being ecstatic, he reached towards the door knob, pausing in the way as he heard muffled deep moans.
"Who was doing the deed in the middle of the class!?"
He mentally face palmed as he was prepared to leave when he caught a glimpse of the person occupying it. A man was sprawled on the toilet with his super thick and juicy plump ass in the air as he continued to shove a large sized glue stick inside, his hair was wet as it touched his sweating skin and suit and his hand gripped hard on the tiolet tank.
It was indeed quality live porn, Childe had thought. The man seemed familiar too. Childe being a man who loved to create havoc and drama couldn't let this opportunity slip by. He reached for his phone and took a picture.
But unlucky for him, his flash was on which illuminated the enitire stall.
Zhongli turned around with his half opened eyes and flushed face, realizing what had happened, he tried to take the glue stick out with panic before Childe grabbed his hand.
"Oh? Who do we have here, Zhongli Xiansheng. I didn't know you were the kind of man to go and put a glue stick in your ass."
It was at that time when Zhongli had feared for life the most. After straightening himself, he looked into Childe's eyes, knowing he won't delete the picture even if he asked him too.
"What is that you acquire for you to dispose the picture permenantly?"
Childe smirked and went closer.
"I mean, you've got such a nice ass, better than any of the girls I slept with, can I try? I promise I'm clean, then I won't spread the picture around."
And Childe knew he would recieve a yes as an answer.
"..."
"Very well then, my body is in your possession."
Childe smiled before yaking Zhongli to the same position and spanked his ass until it turned pale red.
"Say, Xiansheng, how about we do something else than me giving you my dick? why were you doing this anyway?"
"I was-ah!"
Childe took the slippery gluestick and inserted it back slowly, teasing the red throbbing hole, taking it out slowly then going hard in, trying to find the sweet spot.
"Where did you get this big of a gluestick? Wait...Did you get it because you were embarassed to by a real dildo?"
"Uhng"
Just pretend it's my dick Xiansheng, except mine's a lot bigger, I don't wanna break you, I'm sure your virgin ass would love it when its bluging out of you.
Zhongli shifted uncomfortably as Childe knew he had just won a lottery, he was absolutely gonna wreck this man's every inch.
"Childe, stop-ah!"
Zhongli moaned as he heard noises from the outside.
"Xiansheng, don't worry, I won't let them see you."
He gripped harder at the tank as Childe got more vigrous with his movements.
"Ugh Xiansheng, you're so good at this."
He unbuttoned his pants and took out his throbbing cock and started to match it with his other hands movements.
As he thrusted, Zhongli was forced to let out a moan that much louder and desperate than others, he moved one of his to cover his hand.
"Looks like I found it huh? You shouldn't cover your mouth Xiansheng, let me hear how I wreck you."
~~
"Geez, what's taking him so long?"
Aether complained as he followed Xiao to the mens bathroom.
"Aether, you should just forget about that scum's ass."
Xiao reasoned as he checked to see if any of the stallks were vacant.
"What if he died!"
"A man like him who just died while going to take a shit? Really? This isn't the time for jokes-And none of them are empty!"
He threw his hands in the air and followed Aether who cautiously moved towards the end, he peeked from the opened door and immediately became a tomato as he saw two men doing dirty stuff in the bathroom.
"Aether, what're you-"
Xiao's mouth was shut by the blonde, wondering what was up, his eyes scanned the bathroom and shot up with terror as he grabbed Aether and ran out.
"That-That thing! I'll mutilate his ass tomorrow! I can't even take a peaceful shit!"
Aether pressed his hand against his heart while his head was going crazy.
"My God! Now he has broken my boyfriend too!"
Xiao took the other man to somewhere safe.
~~
"Childe-Someone's here-!"
"Shh Xiansheng, I'm pretty sure I locked the bathroom, I don't want anyone else to see your flushed face."
As Childe thrusted the glue stick, he pumped himself and he was on the edge of releasing, with a low grunt, he shot his while liquid all over his history teacher's plump ass.
He took the glue stick out and slapped the ass with dripping thick liquid.
"You look so good for me, covered in my juices."
He rolled his eyes and started to massage the pump ass with his warm cum, teasing the throbbing hole sometimes.
"Let me see your face one more time Xiansheng."
Zhongli turned around with his mouth still open, his tears and saliva were rolling down as his front baby hairs were sticking to his oily forehead while his pants were soaked in his dripping juices.
"Aw, how many times did you come?"
'Such face.'
Childe was mesmerized how sexy a history book can be, he almost wanted to go for a second round but it was already late, he passed Zhongli a pack of wet wipes from his pocket and held out his phone, deleting the picture in front of him.
"Clean yourself and your ass with these, apply ice later."
"Ah, many th-thanks."
The other man laughed silently, he couldn't let go of this masterpiece, he'll just recover this photo later and when he graduates, he's gonna tease Zhongli all he wants.
He smiled at the panting man and pulled him once more.
"Send me a list of the sextoys you want, whether they are ten or a hundred, I will by them for you, only if you send me picture of youtself using them as payment."
Zhongli's eyes widened as Childe left.
~~
When Xiao saw Childe, he took out his scissors and aimed towards him.
"Childe, run!"
While Aether held Xiao down.
Childe couldn't be more ecstatic when he heard his Gmail's ringing sound.
