HA1KYUU X reader - when they walked in [y/n] reading/watching yao1

HINATA SHOYO

At [y/n]'s house
Hinata and [y/n] have been friends
Since childhood- they basically know much about each other however Hinata doesn't know about [y/n]'s secret side . [y/n]'s secret side is that they are a freaky person and not really much innocent; [y/n] reads/watches yao1 and kinda like a sadist in bed.
As Hinata was spending the night at [y/n]'s house, he went down stairs to get something while [y/n] was on their phone reading/watching yao1 without any shame since it's their house and rarely anyone home. [y/n] was reading/watching yao1 until Hinata came from down stairs; he sat next to [y/n] wondering what they're looking at their phone intensely.
" what are you reading/watching ?," Hinata ask with a curious look on his face.
[y/n] responded with " you'll see" with a smirk on their face .
When "THAT PART" came up Hinata blushed hard and staring hard at the screen not knowing that there was a budge; [y/n] glanced at Hinata seeing that his d1ck was hard and kinda wanted to help him out.
"need help", [ y/n] said straightforward
Hinata blushed harder and said " n-no it's okay, I'll handle it myself ."
[y/n]'s expression was meh when Hinata said that , so they turned off their phone, put it down, and got on top of Hinata.
Hinata was shockingly screaming, " [y- [y/n] w-w-what are you doing ?!!!?"
[y/n] replied , " Hinata- or wait no , Shoyo~. You know it's bad to lie"
[y/n] knew the whole time that Hinata liked them and kept it lowkey.
As [y/n] was on top of Hinata they gave him a passionate kiss,  and after the kiss they said," you know that we could do the same thing like them * referring from the manga/scene*, [y/n] said to Hinata.
Hinata gulped and shyly nodded his head giving [y/n] permission to touch him.

SMUT COMING THROUGH-

      *moaning noises* {from all the passionate kiss/fingering/love bites from [y/n]-also from giving head}
"[y-[Y/N]?!!?" Hinata screamed as he was feeling pleasure and pain when [y/n] put in their d1€k/Toy d1€k.
"Ahh~ Hinata you're tight"[y/n] said whispering in Hinata's ear ;smirking.
* thrust * *thrust* *thrust*
"AHHH~ f-faster" Hinata said looking like a mess
[y/n] stopped -
Hinata looked at [y/n] wondering why they stopped when he was about to come.
[y/n] smirk and said " you can't come yet - be a good boy and ride me or you prefer a punishment" eyeing Hinata up and down.
Hinata did as he was told - he got on top of [y/n] and try to take all of it in, but it was too big for him; [y/n] grabbed Hinata's hips and slammed him taking all of it in.
"Ahhh-" Hinata was tearing up from the pain and started riding [y/n].
[ y/n] stared at Hinata every inch as he was riding them. As they were enjoying the view they decided to tease Hinata, they licked his nipple, jerk him off, biting him, leaving hickeys, and lastly kissing passionately. 
" [y- [y/n] I'm coming" Hinata said and c^m all over [y/n] body - lying on top of them.
"You did great Hinata, I'll clean you up" [y/n] said and kiss his forehead.
"I love you" [ y/n ] said before going to sleep after cleaning up.
They cuddle each other as the night was peacefully quiet with the moon shiny bright.
The next day- at school in the heading to the gym
Sugawara asked Hinata what happen to him since he couldn't walk properly in the hallway.
Hinata blushed remembering the thought of last night and said " nothing I'm probably just tired that's all" looking away from sugawara's eyes.

The end :)
