Together in Insanity (Yandere!Sangwoo x Reader)

Chapter 15

You sighed, glad to finally be alone. You weren't sure where or if Sangwoo worked but he was always home to greet you and often he even picked you up from your own work. It. Drove. You. Mad.

You basically lived here yet he wouldn't allow you to go upstairs. What was up there that he was so desperately hiding? A secret stash of gay porn? Whatever it was you were finally going to find out. Sangwoo believed you were feeling ill and therefore napping but both were lies. You weren't feeling ill nor were you napping. Instead you were climbing up the stairs to the mysterious floor.

And up stairs number one is a… you slowly push open a door, holding your breath, bedroom? You looked around, a bit confused. It was in perfect order so it was clear Sangwoo cleaned up here a lot but, why the secrecy? Was he worried you would no longer share his mat with him? No… You start to look through all the drawers and cabinets, trying to find a clue as to why Sangwoo was so secretive over this room. Somehow, however, you felt you already knew.

If Sangwoo was anything like you, which he clearly was, then you were betting your money that this had been his parents room. However, you didn't like making rash judgements so you still looked for evidence to prove your theory. Besides, you could learn more about who his parents were and what actually drove your lover to killing them.

Slam!

What the hell?! you thought. Silently, you move back towards the door to downstairs. Is Sangwoo home early?

You peeked down the stairs and caught a glimpse of black hair walking into Sangwoo's bedroom. That's definitely not Sangwoo, must be one of his fans. You smirked and quietly descended the stairs. Wouldn't it be such fun if we had two pets? We could have them play together and have little competitions.

Creeping down the hall, you looked around the doorway to see the intruder molesting Sangwoo's pillow. You held back a laugh as you pulled your head back so Sangwoo's fan wouldn't see you.

CLANG!!

Shit! That damn bitch! you thought angrily before realizing it didn't matter. If you were to keep this intruder as another pet, it would only be a matter of moments until they met. But now, thanks to the stupid bitch in the basement, the new pet was going to willingly walk down into the play chamber. It was all too easy.

You covered your mouth to stifle your laughter while you heard the creak of the trap door opening.  Listening to him trudge down the stairs, you waited to enter the room only to have your shoulder grabbed. Quickly, you swung around to face your attacker, only to realize it was Sangwoo. You silently pointed to the stairs. He nodded.

His hand remained on your shoulder until he went into the room first. The light brunet took silent steps to his closet and grabbed his bat. His slow steps gave you ample opportunity to check out his ass before following. Then, it was down the stairs.

“Save me! Save me! Please save me!” the blonde bitch begged. You held back a sigh as you descended the stairs. It seemed like you had just finally shut up her begging for help when you stuffed the gag in her mouth over a week ago.

“H-Hey! Calm down,” the intruder said. Clearly the bitch’s screams were racking on his nerves.

It only took moments before her eyes locked on you two. “Why are you doing this to me!? Please…!”

“Um… Let me untie you first…” the male reached for the rope on her body. Clearly he had no idea Sangwoo and you were walking towards him across the concrete floor.

“Kyahh! Stay away! Stay the fuck away I said!”

“N-No, I just… wanted to untie you…” You almost laughed at the obvious confusion in the male’s voice. She couldn't have made it more obvious her oppressors were in the room unless she screamed “turn the fuck around.” But now, it was too late. Sangwoo had up his bat and-

Thwack!

A blow to the arm. The make fell on his side, screaming in pain. Sangwoo shoved you back with his other arm, causing you to land on your butt next to the squirming bitch. It was clear he wanted you out of the way and this time, you were actually fine sitting back and watching your sexy lover do his stuff.

“I don't know who you are, but I haven't seen my relatives in ten years.” Sangwoo said. His dominate and protective tone was really quite a turn on. “You might as well have said you're my brother.”

Pathetically, the man tried to crawl away. Sangwoo followed behind. Sangwoo grabbed the man's hood and dragged him back. The man elbowed the back of Sangwoo's knee and ran upstairs. Sangwoo recovered and swung the bat at the back of the man's legs. The man fell back off the stairs. You were tempted to go get popcorn if you wouldn't miss the show. The bitch next to you wouldn't stop making noises, however, so you stuffed the gag, back into her mouth to silence her. It made you feel a part of the fun.

Now the man had crawled away so his back was against the wall. Sangwoo was poised to kill. Shit! You jumped up and ran towards the two until the intruder opened his mouth.

“I fell in love!” You stopped in surprise. Sangwoo didn't swing. Both of you waited for the male to continue. “Sungsoo University class of 2011! I was in the same class as you! I also saw you in the army…” the male took in a shaky breath, clearly getting emotional. “You saved me from my superiors! And from then on I..!” His voice broke. You slowly walked closer and noticed the tears rolling down his pale cheeks. “...I never intended to annoy you like this, but I liked you too much!”

A small pang stabbed into your heart. Am I… jealous? Of this pathetic creature? He truly was in a pathetic state: unhealthy, malnourished, possibly dropped on his head more than a few times. Yet he was sort of cute.

Sangwoo was just as lost and confused as you were, although clearly not jealous like you might possibly be. You took this opportunity to break him from his trance by hugging him from behind. Your lips gently kisses and sucked on his neck, relaxing him from that thrill edge you knew he was on from almost killing the male.

“Awe.~ He's cute.~ Sangwoo?~ Can we keep him?~” You stood on your tippy-toes to peck his check as your eyes locked onto the male cowering on the ground. “He can be our pet.~”

“Keep him as a pet?” Sangwoo frowned, confused.

“Yeah.~ You can be the daddy.~” You take the bat away and move around him so you were facing him. “I can be the mommy.~ And he can be our puppy.~”  You peck his lips. “Pretty please?~”

Sangwoo wrapped his arms around your waist before replying boredly, “I guess.” He picked up his bat again. “This basement is too small for both of them. Let's take him up.”

You smirked, understanding his meaning perfectly. “Of course.~” The three of you started up the stairs.

Near the top, you turn to Sangwoo, “Are you going to do it or shall I?~”

“Do whaa-” The male didn't finish as Sangwoo shoved him down the stairs, breaking his ankles and knocking him out cold.

“I guess that answers that.” You turned to go back down the stairs, only for Sangwoo to grab your waist and pull you towards him. “Wha-” you started but he interrupted.

“You're mine. I don't want him touching you, speaking to you, or even looking at you without my consent.” His grip tightened on you. “If he does anything, I want you to tell me immediately.”

You tried to laugh off the uncomfortable air. “I hope you're not becoming too possessive Sangy.~”

“Don't call me that.”

“Why not?~ I like it.” You wrapped your arms around his neck and in a sing-song voice you breathed, “Sang-y.”

The next thing you knew, he picked you up and had stripped you bare at the bottom of the stairs.

“Sangwoo.~” you moaned as he thrusted roughly into you. The ice-cold concrete made your back arch to get closer to his warmth. It was animalistic, dominant, and rough sex. Each thrust seemed to be him claiming you. And you loved it.
