Hey, a few things I would like to point out here before we get started.

One, there's a bit of profanity in here. I'm used to writing content with swears nonetheless so it's not really a surprise to most. Also, it's kinda like my second language at this point-

A few warnings I'd like to point out: This is a Yandere oneshot, and topics of blood, jealousy, death, and weaponry are bound to be mentioned. Please proceed with caution. Also, this is smut as well. If you're uncomfortable with sexual topics, please don't read this either.

I tried writing this the best I could and hope you guys enjoy. Sorry if I didn't get it exact to the request. But eh, I still think it's good so eh. And in this oneshot, Ruby isn't with Mark and Cj won't be with Vade for plot reasons. :>

Art for this chapter ain't mine.

-----------------------------------------

A long sigh of relief escaped your lips as you finished your abundance of work for the day. You weren't the first one to be finished, but you definitely weren't the last. One of the many people who finished around the same time as you was Ruby, already beginning to pack up to leave for the day. Talk about impatient. You couldn't blame her though – college classes sometimes sucked ass.

You and Ruby were good friends, spending as much time as possible with each other. It seemed as though Ruby had no one else to be with except her band and you. Which, you didn't mind but it seemed a little sad. You wished she'd get more friends, however, bringing that up last time didn't end too well.

The bell soon rang through the classroom, alerting everyone that the day has now ended. You – along with everyone else – began packing up, some already heading out to their dorms. Ruby waited patiently beside you, watching you pack up your things. It didn't take long for you to finish, about to step away from your desk and leave with Ruby. However, a certain someone had stopped you.

"Hey, (Y/N)!" A feminine voice called, causing you to turn around to the sound. Looks like the voice came from the one and only Vade.

"Oh, hey Vade. What's up?" You reply, smiling her way. You didn't exactly know what she wanted, but you didn't pay much mind to it.

"I was hoping you could come to my dorm room tonight to study," She replied, smiling back at you. However, something different was in her eyes that you couldn't point out.

You gave her a guilty look, feeling bad for what you were about to say next. "Sorry Vade, but I'm busy-"

"Pleaassee? I can order us food too! And if you want, you could sleep over too!" Vade interrupted, whining a little afterwards.

"No, no. It's fine. Maybe another time?"

"But why not today? I have something I really wanna show you!"

"Just please-"

"Enough." You heard Ruby say, now standing in front of you as if protecting you from Vade. "Y/N said he was busy today, so stop pestering him. Now."

Vade's expression changed entirely from before, her eyes evident with fear. You couldn't help but be frightened yourself, especially because the both of you haven't seen her do this before. And in such a threatening tone too. It was unlike her, and neither of you knew the reason for it. It didn't even look like Vade wanted to know the reason, since she just ran off without a word.

"W-What was that for?" You stuttered, looking towards Ruby for an answer. She didn't respond to you, however, grabbing your hand and guiding you out of the room.

"W-Where are we going?" You asked again, however there was no response given.

At this point, you knew something was very wrong. Something wasn't right, and your stomach churned in worry. Even after the many years being by Ruby's side, you never saw her act this hostile. She was always so shy, kind and didn't really speak a whole lot. It wasn't normal.

Maybe something happened between the two girls? Like a fight you were unaware of or a disagreement? Either or, you didn't know, and you were definitely tempted to ask. Although, you very well knew you weren't getting an answer.

Moments pass as the both of you silently make your way throughout the college, soon stopping at your own dorm room. You walk up to your own dorm room door, unlocking it and opening it for yourself and Ruby. You walked in and held it open like the gentleman you were, but Ruby never followed in.

"Umm...you coming, Ruby?" You asked, feeling nervous to even ask such a question. That was when she walked up to you, not even inches close to your own face. You felt your cheeks heat up at how close she was, your heart pacing violently in your chest. You were just about to say something, though the white-haired female right in front of you beat you to it.

"Don't go to Vade's tonight." She said in a threatening tone, her pink eyes piercing through you menacingly. Adrenaline ran throughout your entire body, your e/c eyes widening as you looked at her.

"W-Why? I-I already told her I'd be busy." You questioned, hoping you'd get an answer this time.

"Just don't. You won't like what you see." That was all she said before she stormed out the door, leaving in the direction of her own dorm room.

You had to admit – you were terrified. Your heart shook violently in your chest, fast breathes escaping your lips as you finally shut the door. What was going to happen there? What didn't you want to see? And why was Ruby acting so...strange? It was as if you didn't know who she was anymore.

Even if you were so enticed with fear, you still were curious. You wanted to know the answers to all these questions that bashed around in your skull. Maybe you'll actually go to Vade's dorm like she asked. At least it'll make her happy.

And just like Ruby had said, you really should have stayed away from Vade's dorm room. You knocked on the door a few hours later, the door opening slightly. However, no one was opening it – the door was previously opened and never closed properly. You decided to step inside, only to be met with an ungodly sight.

"I told you not to come here, (Y/N). You didn't listen." Ruby stood at the back of the room, blood stains across the entire floor. And right on the ground in front of her was Vade, the person's room you had just stepped into. You were right to be frightened before. Only if you just stayed in your dorm room like Ruby told you to.

"S-Sorry, I was curious by what you said earlier," You replied, refusing to make eye contact with her. Though the only thing that caught your eye was Vade's lifeless body on the floor in front of you. At least, it appeared to be lifeless.

"Ever heard the saying, 'Curiosity killed the cat?'" She asked, stepping closer to you. You stepped back for every step she took towards you, finding yourself backed into the door you had just entered. Ruby soon lifted the blade that was in her hand and motioned it towards my chin. "That could very well happen to you too, just as it had happened to Vade."

And...that answers your suspicion from earlier. You gulped, feeling the edge of the blade slightly piercing your skin. You were indeed in a shit ton of fear, but what you didn't expect is how arousing this was to you. The feeling of your life being threatened, and the small feeling of knife Ruby held piercing your skin. Not to mention how crazy she was being right now.

"Why did you kill her?" You bravely asked, your e/c only showing fear. No arousal seemed to be detected within them.

"I did it for you," Ruby replied, a smirk making its way to her lips. She let out a small chuckle, getting even closer to my face. I could feel her breath on my face, both wanting to push her away and close the gap between us. "I did this all for you, dear. With her gone, there's no one else that can get in our way."

"W-What do you mean, Ruby...? In the way of what exactly?"

"In the way of our love, (Y/N)."

Damn did this ring a bell, but what exactly was this type of behaviour called again? Obsessive, crazy? No...it was something else. Yandere, right? You couldn't help but laugh in return to her response.

"Y'know, you didn't have to do this. I would've chosen you over Vade any day." You confessed, a slight tint of pink dusting your soft cheeks. "Although, the way this was presented is quite intriguing. Care to show me how much you really want me~?"

She flushed up at your words, caught off guard by what you said. Her smirk only grew wider though, hints of lust evident in her expression. "I'm more than willing to, (Y/N)."

She set the knife down on a nearby dresser, kneeling down in front of you. Once she had, her hands fumbled with your pants/shorts and pulled them down, along with your underwear. Your cock was now exposed to her, standing up proud and ready for some action.

Ruby began licking the tip of your cock, receiving a few soft whimpers escape your lips. It wasn't much, however, because of how little it was, you desired more. Thank God it wasn't long until she took in some of your rod, sucking on it while her right hand jerked off the part she hadn't had in your mouth.

More moans flowed out of your mouth, finding it more pleasurable as she continued to suck you off. The soft and wet feeling of Ruby's tongue guiding along your shaft caused a shiver to crawl up your spine. It felt so undeniably good, making you think that Ruby has done this before. You weren't so sure, though you were curious. Maybe you could ask later.

You reached your hands down to take her beanie off her head, throwing it aside before gripping gently onto her snowy hair. A few moans escaped her own lips, sending vibrations down your shaft which made you release a much more desperate moan in return.

"F-Fuck, Ruby~..." You muttered aloud, tugging slightly onto her locks. More moans escaped both of you lips as she finally took you all in, bobbing her head back and forth to give you complete pleasure. Damn, who knew this would get sexual after someone's death? Oh wait, you did. :D

It wasn't long before you felt the urge to release, your moans becoming more strained, yearning to cum. You knew Ruby knew too because went even faster, helping you chase your climax. A few seconds later, a warm liquid flooded out of your cock, some of the white fluid dripping down the side of her chin. She took her mouth off your cock after swallowing it, licking her lips and the tip of your dick, not wanting to leave any excess behind.

"D-Damn you taste good~," Ruby panted out, looking up at you as she spoke.

"That's only the beginning, hun. The real fun is about to start soon~." You replied, leaning down to grab her hand and guide her to the spare bed in the room. It seemed like the bed wasn't ever used, but that was going to change fairly quickly. You were about to pin her down on the bed and fuck her then and there, but she beat you to it, pinning you down on the bed and climbing over top of you. Even if you wanted to switch places from underneath her, you were soon unable to, as she began trying your wrists to the bed post, preventing you from moving.

"Nu uh, dear. I'm topping. I'm the one with the knife, remember?" She retorted in a semi-threatening tone. Another chill crawled slowly up your spine as she said that, but your dick only grew hard once again. This was both the most terrifying and arousing thing you've ever experienced in your life.

It wasn't long before she stripped the both of you completely, leaving a few hickeys on your body here and there. She needed to let you know and others that may get a hold of you know that you were hers and hers only. Ruby had thought about using her knife on her to give you more marks, but you seemed to obey well enough to not warrant that.

"Let the real fun begin," Ruby said out loud, sitting down on your cock. You could feel her wet insides clenching around you. You groaned deeply, throwing your head back in pleasure.

"(Y-Y/N)~," She moaned out, clenching her eyes shut. She must've been in a little pain while doing this, a look of concern painted across your features. The white-haired woman on you noticed this and replied again. "I-I'm alright, don't worry. I'll begin moving soon."

And what she meant by soon was right now as she began to ride you. Of course, it was only a slow pace to start out with, but you could live with that for a small bit. Too long though and you might go insane.

Both of your moans mixed together in sync, as if singing a duet together. And those voices soon grew louder and louder as her pace on you grew faster. You couldn't even help but thrust up into her, allowing her moans to grow more desperate and needy.

"(Y/N)~!! H-Haahhh~!!" She moaned loudly, unable to control her noises. Her pink eyes crossed slightly too as she attempted to look down at you. Looks like the neighbors will hear what happened tonight, especially because they heard your loud ass moans too.

It wasn't long for the both of you had gotten close to releasing once again. "F-Fuck, I'm close Ruby~!" You warned, looking up at her for any sort of reaction to what you said.

"Cum in me, (Y/N)!" She begged. And so, she got exactly what she desired, the both of you climaxing at the same time. The sound of each other's names being cried out in unison was heard loud and clear by probably everyone in the dorm rooms.

After that, you and Ruby panted softly, your eyes matching her own. "Holy fuck...We have to do that again." You suggested.

"Does that mean that you're willing to be mine?" Ruby asked, a hopeful look in her eyes. She looked sweeter this time, unlike the previous scarier expression from before. It was nice to see it again.

"Of course, Ruby." You replied, giving her a gentle smile in return.

"Good, cause no was never an option."
