Together in Insanity (Yandere!Sangwoo x Reader)

Chapter 24

(Quick Summary: You, the reader, got basically fed up with Sangwoo and him denying his feelings for you. so, last chapter, you ditched Sangwoo and were fucking some chick (Heather). Last sentence: "You could feel yourself on the verge of release when Heather screamed and everything turned red." Enjoy!)

You stared at her in shock. Heather's mouth remained in a large O. Her once innocent eyes lost their gleam and remained fixed on you in a lifeless gaze. Blood spilled from her chest where the silver glint of the tip of a knife protruded from her chest. The knife retracted and the body fell over onto its side, leaving you face to face with her killer.

"I thought I told you. You are mine."

Rage and jealousy flamed in his eyes. If he doesn't give a shit then why is he always so jealous? Either he was a really good fake that you couldn't see through, unlikely, or he was in denial of his feelings, far more likely. No matter what it was, you were barely able to process the situation through your shock.

His lips collided against yours, pulling you from your trance. You pushed him away and smacked him across his face. "What the fuck is wrong with you!?! Didn't you see I was busy?"

"No one else is allowed to touch you, much less make you cum. That's what I'm here for. Was this the supposed appointment you had to run off to? To hook up with some slut?" He looked at her body with great disgust.

"What I do is my business. Who do you think you are to tell me who I can fuck?"

"Your lover." He turned his dark eyes back upon you. It was clear he was trying to control his anger and emotions, shoving them under a rock.

"So? If we are nothing more than booty call to each other, why can't I have some fun with anyone else I please? You don't control me." You stared at him right back. The rage in his eyes reflected in yours. It was clear that he believed he did control you. "You said yourself we are only friends-as if sociopaths are able to have friends."

Sangwoo was clearly at a loss for words. It wasn't him to admit he had feelings for you, if he had them, but he couldn't explain his motives any other way. He himself may not even be aware of his reasons and feelings. Maybe he was in denial like you had been for so long.

"You are mine." he reiterated with a voice of steel.

"If I am 'yours' as you say, then clearly we are more than simple friends. So what are we? What is this to you?" You weren't backing down. Either he was going to admit his feelings or you were walking out.

"Lovers."

"Lovers aren't possessive. They don't own the other. It's a booty call relationship. Is that what this is?"

Sangwoo clearly knew where this conversation was going. He sighed in frustration, giving in. His forehead pressed to yours as he sighed. "Fine, boyfriend."

You would never admit it but as he said that your heart fluttered. Yet it wasn't the same. You didn't want him like you had so many times before. So when his lips pressed yours, your lips moved with his to simply go through the motions. The hunger and desire you had in him before were gone. Kissing him was, well, boring. The spark now nonexistent.

His hands moved along your sides, exploring your bare skin. They moved down to your ass, gripping it tightly. His boner pressed against your wet folds as he pulled you closer. Slowly, he moved his hips against yours. His lips left yours and moved down your jaw and neck. The feel of his teeth and suction of his lips told you he was purposely leaving marks. His hands moved from your ass, sliding ever so slightly against your sides to your breasts and giving them a firm squeeze.

You weren't having it.

"Stop." you stated firmly, fighting back moans. Your hands fumbled against him before they firmly landed on his shoulders and gave a hard push. Sangwoo resisted but you pushed against him harder and he finally broke away. His dark eyes glared into yours.

"What." he demanded.

"I'm not in the mood." You moved to get away but he held you down.

"You seemed to be in the mood a few minutes ago."

"That was before you killed the bitch I was fucking."

"What and that turns you off? Last I recall, you loved it when I fucked you after a kill."

You couldn't argue there. It wasn't that you didn't want to screw right then, you just didn't want to be screwing him. The whole point of a hookup was to get over him, and you if you were under him, you ain't getting over him.

Your silence he took as a cue to continue. His lips went back to where they left off, sucking and biting your neck and shoulder. There was a soft prick of pain as he nipped at your collar bone. Your head leaned back as he kissed down your chest. Were you okay with this? You weren't sure anymore. You weren't completely against it and with every kiss you wanted more and more.

Fuck it. Grabbing his hair, you pull his head back up to your lips. His lips quickly reciprocated the eagerness in your kiss.

"Now that's more like it," Sangwoo muttered as he pulled back for air. You could hear the smirk in his voice.

"Shut the fuck up." you growled back. The light brunet only hummed in response as he kissed back down your neck; his hands kneading your breasts as he sucked on your skin. It was clear he had every intention of marking your neck for everyone to see. If he thought that would stop you from fucking strangers, he had no clue to the powers of concealer and foundation. Plus, why would a bunch of horny drunks even care?

You pulled his turtleneck sweater off over his head as his hands left your body to unbutton his pants. His brown eyes stared into yours while he unzipped his jeans and pulled down his boxers. Sangwoo wasted no time before thrusting roughly into you. Your hands flew to his shoulders, nails digging more into his shoulders and back with each slow, hard thrust. His hands lifted your ass off the bed and pulled you to him to meet his every thrust. It didn't take long until you were a moaning mess.

The dead bitch's blood dripped down your back. Her blood had soaked into the white sheets and covered your body. One of your hands trailed down your lover's chest, smearing the crimson around his pecs and abs. You couldn't even remember her name, but the way her red colors joined you and Sangwoo in this moment created a feeling that nothing could compare to.

For once in a long while, it felt like when you first started being partners in crime. Back when everything was about getting ass while killing disgusting, two-legged creatures. Before his obsession, before you had feelings, and before Yoon. It was amazing. You loved it. Nothing had ever gotten you so high and you doubted that anything else ever would.

His hands kept groping your ass, squeezing it tightly in time with his hard thrusts. He leaned forward to pin you against the bed as he thrusted faster. You wrapped your legs around his hips only for him to left one of them over his shoulder.

"Sangwoo.~" you moaned, feeling yourself get close.

"Enjoying yourself?" The smirk was obvious in his voice. You would've shot back a sassy response, but everything went black from the force of your orgasm. Sangwoo thrusted a few more times before cumming inside you.

You panted heavily, coming down from your high. "You better not get me pregnant." you threatened. Sangwoo only chuckled in response.

(Sorry for a lack of updates; I'm not even going to try to excuse it. This officially makes 115 pages of this story-in google docs, Times New Roman, size 12 font-so yay. For those of you that have stuck with my bad writing and inconsistent (nearly non-existent) updates for this long, thank you very much!
