Meh, with all the RWBY hype, I've been in the mood to write a rather dark fic. I do not condone any of this behavior in real life. That still doesn't justify writing this.


Mercury kept her pinned underneath him. Yang struggled under him weakly. They had fought all day, until she had worn herself out. Before fighting him, Neo had returned to fight Yang as a form of vengeance. Neo had tired her out beforehand but Yang had beaten her out of commission. Mercury ended up stumbling into them after they had fought. Seeing that she had been weakened considerably, he decided this was a good opportunity to fight her. He had to admit, this blondie was something else. Even as her muscles quaked from excessive use and almost crumbled under him immediately as he held her down. He was about to choke her to death but seeing that she was about to die, tears fell from her eyes.

"Ruby... I got..." She uttered out.

"Hmm?" Mercury asked, hesitating.

Yang surprised him by landing one more punch, throwing him off of her. But she couldn't even get up because of how tired she was. Still, Mercury was curious as to what she was going to say. So he walked up to her, slowly. She staggered onto her hands and knees.

"What were you going to say, Blondie?" Mercury asked.

"I got to... help Ruby." She said.

"You're not much help. Not anymore. Now hold still or you'll die even more tired." He said, walking up to her.

"No... I'll... Do anything." She said, reaching for her shirt.

Mercury was curious. What could she have to offer that would be worth sparing her? It was almost laughable. But then... there was one thing that could maybe prolong her life for a moment. She then pulled down her shirt suggestively, nearly exposing one breast. Actually, he realized what she was implying could be fun. Why not defile her? It was worse than death after all. She was about as worthless and as limp as a ragdoll right now anyway. So he approached her.

"You're close to death and you want me to defile you? I'm usually not that low." He said.

"You technically have my permission... Just let me live." She said.

"How do you know I'll let you live after this?" He asked, putting a hand on her.

"...Then just kill me now if that's the case." She said.

Mercury picked her up and threw her over his shoulder. He never had actually ever laid with someone before so he was very excited in more ways than one. It was almost like he was fifteen again for a sec. Oh boy! He was going to get some! Yang felt embarrassed but if it meant she'll still be there for Ruby, then this was going to be nothing. If giving up her virginity to the enemy meant she could live to look out for her sister again, she'd do it without hesitation.

"You know what? I'll take you up on your offer. But if you change your mind or do anything to hurt me, I won't have any second thoughts about killing you. The same goes for after this encounter." Mercury said.

"I won't. I promise... Let's just get this over with." Yang said.

Mercury then carried her off into the woods. Yang didn't bother putting up any form of struggle as he carried her. She was almost tempted to pass out but knew that he could kill her if she did. She was going to see this to the end. Then they arrived at a cabin that was almost perfectly camouflaged so much so that Yang herself probably would have ran into it before realizing it was there. It was an old huntsman cabin that was put here as a safehouse for other huntsman. Mercury kept it as his own personal hideout. None of Salem's allies or even Emerald knew of this place yet... mostly because the others haven't needed it so he never bothered showing or telling anyone about it. In the end, Mercury still preferred solitude but he was more than happy to have his new companion over. He was definitely not going to forget this. Mercury opened the door and they went inside the dark cabin, never to be seen again for hours or maybe even days. As far as far Emerald and the others were concerned, he's just working and nothing else.

Mercury tossed Yang onto the bed in the corner but he didn't jump on top of her or anything. No, he wasn't going to just claim his prize right away. He wanted a minute to sit down for awhile. Yang looked over at him nervously as he sat on the edge of the bed. Her eyes soon adjusted to the darkness of the cabin as Mercury sat on the bed, relaxing before getting to play with his new prize. Yang shakily sat herself up with what strength she could muster. She was nervous more so than ever and though curious about his hesitance, she didn't dare ask why. Soon, however, Mercury started removing the armor off of his arms, revealing a few mysterious scars covering his arms. He got up off the bed.

"I'll go make things a little more cozy. I suggest you make yourself comfortable if that's even possible in your state." Mercury said before walking away.

Yang looked at him, thinking deeply. Finally, she let out a sigh and started taking her clothes off, letting them drop off the side of the bed. She may flirt with a lot of men, even had a few boyfriends but, she herself never actually went all the way. She decided to better her chances of surviving this by giving as much of herself as she could to him. Even if she can't really feel any love for him, she was going to try and pour as much of herself into this. She wanted to see if she could get him to become attached. After all, he did go to school with her once. Mercury, meanwhile, lit the fireplace and stoked it so a decent fire started burning. He wanted it to be warm for the night. He also took his shirt off and left his grieves on the coffee table. He wasn't going to take off his pants, not fully. He was still self conscious about his legs. He'd never pull his pants down past his prosthetic legs anytime soon in front of Yang. It's advised for him to sleep without his prosthetics but he rarely even does that. He wouldn't be caught dead without his legs... he also didn't want her to see even if she probably already knew. Her metal fist connecting to his legs probably gave it away in previous fights.

He walked back over to the bed and was surprised to see that she already had no clothes on. The sight surprised him and Yang grew a little flustered but forced herself to look at him despite her nerves. He was also a little nervous because he was new to this. Her body was perfect, her hips broad and her breasts well endowed. Many women would kill to have a body like Yang's: not too thick, not too thin, just right. The way her golden locks cascaded down her back and on her shoulders added to her looks. Her prosthetic arm looked like a part of her, almost completely natural. Mercury felt like the wind had been knocked out of him. An obvious boner formed in his pants. Yang grew a little impatient even though his gawking was as nerve wracking as it was somewhat flattering. She really just wanted this over with.

"If I'd known stripping would have had this effect on you, I should have just fought you naked." Yang said.

Mercury smirked and walked over to the bed.

"It wouldn't have worked. If we were in a fight right now, I wouldn't bother with this. I'm only staring because I can... although the thought of you fighting naked sounds really hot. You can try it if we ever fight again." He said, sitting on the bed.

Yang silently prayed her team would find her soon but Mercury's hand on her cheek brought her back into focusing at the problem at hand. Mercury was looking at her with a smugness that she wished she could punch. But she restrained her urge to hit him by leaning into his hand slightly, her arms resting at her side. It was better she gave in to him right now than risk her own life. In normal circumstances, she would resist in some way but she couldn't afford to do that. If he holds true to his promise and lets her go after this, she was going to make sure he paid for doing this next time. He rested his forehead against hers, surprising her with this oddly intimate gesture.

"Relax, blondie. It's not like I'll make this all that unpleasant." He said.

"Just... shut up." She said, closing her eyes.

"Alright." He said before claiming her lips with his own.

Yang felt her heart beat wildly from nerves. She was scared but as she felt his lips against hers, she made herself kiss him back. She decided to pretend for the moment that the man taking her into his arms didn't just help cause the fall of Vale, that he didn't help cause the death of Penny, Pyrrah, and thousands of innocent people, that maybe none of that happened. She could have loved him if it wasn't for that... he was cute enough. If only he wasn't a bad guy... She forced herself to just act as if none of that ever happened. She pretended that maybe this was a result of being at a dance and in the heat of the moment, he had brought her home. Her muscles would be sore from dancing instead of fighting. Young, free, and horny love stricken teenagers just having some fun. Yang focused on that thought as she rested her hand on his thigh while they kissed.

Mercury hesitantly put his tongue in her mouth. Yang could tell with how uncertain he felt that he had no experience with this. So she obliged and took the lead, swirling her tongue around his until he got a better idea of what to do. Mercury gently pushed her down onto the bed, his mouth not leaving hers at all. She let out a short, nervous, whine from the back of her throat. Mercury almost forgot that she really did not want to do this. The thought bothered him but he made himself focus on what he was doing and what he wanted out of this. He groped one of her breasts and she groaned into his mouth while he fondled her. Yang hesitantly put her arms around him. Mercury then parted for air before focusing his attention on her neck while Yang laid there, her aching body not able to do much but, in spite of herself, become hot from his actions. She could feel Mercury's excitement prodding her leg as he kissed down her neck. She kept her actual hand on his head while her mechanical one stayed on his back. He moved down to the valley between her breasts and she couldn't help but make some nervous noise that, if she wasn't so nervous and unwilling, would have been pleasured moans. He then smirked as he moved to give her breasts some attention.

He took on of her nipples into his mouth and swirled his tongue around it while squeezing the other. Yang whimpered, her hand now gripping his hair while her mechanical arm moved to grip the bed. Mercury felt accomplished that he could make Yang feel good even if they were enemies. She didn't want to feel this but she was and he was the cause of it. Oh how he loved turning this girl bad right before his own eyes. It was almost sad to think that she was really just doing this because she was too weak to fight him off. He was curious as to how she was in bed at full strength. But, he also liked how he was the only one in power. She was weak and at his mercy underneath him. He removed his mouth from her nipple and started going down her stomach. He hesitated, wondering if he'd be able to use his mouth on her decently enough. Even if she really was at his mercy, he did not like the thought of being horrible. There's no fun in that. So he did what he does in battle: experiment and watch for a reaction

So he payed close attention when he put his mouth over her vulva, thoroughly licking all parts to see what she reacted most strongly to. Yang was shocked that Mercury actually wanted to go down on her. Not every guy likes doing so but evidently, he really wanted to. She squirmed as he investigated her with his mouth and she would groan or make some slight noise whenever he'd hit a sensitive spot. He figured out her clit was especially vulnerable. He learned quickly. Within seconds, he had her moaning and throwing her head against the bed. Mercury was smug all through this as he lapped her juices. He felt so proud of himself for making her a writhing mess within minutes. Finally, Mercury grew tired of just eating her out. He took his mouth away from her and she looked down at him.

"Wha?" She said, confused.

"I think you're ready to go all the way." Mercury said, pulling his pants down just a little above his prosthetic legs.

Yang grew nervous again, especially when she caught sight of his length. Is it really that length or was that just her? She grabbed it hesitantly. Mercury didn't stop her; he already knew she wasn't going to do anything after all that. He inhaled sharply when he felt her grasp him. He thrusted into her hand a little. She let go and kept her hand at her side. Mercury chuckled and move her legs up more. He then positioned himself, the tip of his dick rubbing against her wet entrance. He pushed into her warmth, inhaling sharply as he did so. She was so tight and so wet. It felt like her body was trying to squeeze him. Yang flinched as he went in. So far, it didn't hurt too bad, it just felt like she was getting stretched further than she was used to. It stung a little but not enough to warrant any real complaint.

Mercury knew he could have just slammed into her. He could just hammer her into the mattress until her blood soaked through the mattress pad. But, instead, he opted to take her slowly, relishing how tight she felt. He'd never admit that the real reason was because he really did like Yang. She was literal fire and Mercury loved a feisty woman but right now, she was reduced to a dim ember. He would be lying if he said he had no affection for her. It's just that he was used to cutting off his own feelings. But, as he hovered over her, her lips met his and he felt himself falter. She was mostly trying to give him a sign to keep going and hope that he would fall under her thumb. She didn't think it would work as well as it already was. His heart started beating faster and his strong emotions won out. He thrusted inside of her gently, kissing her with as much affection as he was capable of. He was normally pretty good at keeping his emotions in check but not tonight. He soon felt a strong sense of possession over her. This was his girl. She was his and his alone. If anyone ruined that, he will take care of them himself. There was no way he could kill her now. He fell hard, in a sick twisted way but her plan had worked: he was under her thumb whether she knew it or not. He would always either keep her under his submission or he'll just die by her hand, both of those thoughts were okay with him.

Yang could feel a change in his demeanor as she laid there, her legs wrapped around him loosely because she really didn't know what else to do with them. Mercury was oddly gentle with her despite the circumstances that warranted where they are now. She figured he would have been rough and forceful but, and especially now, it was almost like he did feel something for her. She was thankful he was at least not trying to hurt her anymore than he has. Yang was too tired to even make anymore noise. She felt her energy drain more and more, as if the act of making love to him was sucking the life out of her.

Noticing a lack of movement, Mercury parted his lips from hers and looked at her. She wasn't falling asleep but they both knew that the moment he gets off of her, she was going to be out. Her eyes were closed and she breathed heavily. He moved his lips to her neck and decided it was better that he finished sooner before she passes out underneath him. He increased his speed and went in harder. This jolted Yang awake a little more than she was and she felt herself getting closer to orgasm. She held onto Mercury tighter. She groaned his name once, which was probably going to be the only time she would manage to say anything that night. The fact that she said his name surprised him but it encouraged him that she was actually enjoying herself to some degree even if she obviously would much rather sleep and be as far away from him as possible. He soon felt himself nearing his release and his movement sped up more. Yang groaned and felt herself starting to cum. When he felt her walls throb and clench against his dick, he also came as he grunted against her, his cum and her juices pooling inside of her.

He got off of her and laid next to her, keeping her under one arm, pulling his pants back up as he did. Yang rested, her breathing slowing. The last of her energy had been spent. Mercury floated in the afterglow and, sure enough, Yang fell asleep within seconds. He stared at her, his mind a clutter of thought and conflict. What was he doing? He is supposed to kill her and the rest of her comrades if he encountered them. He internally berated himself and moved his hand up to her neck. He could easily kill her right now. He could even make sure it was quick and painless by snapping her neck while she slept. But, his hand rested over her neck, her pulse beating softly under his hand. He sighed and got up off the bed in frustration. Maybe it was because of the pain of Cinder dying, maybe it was because of Emerald no longer seeming to want much to do with him anymore, or maybe it was the weight of everything that's happened to him but, he couldn't do it... moments ago, he would have had no problems with this but... she was... his. He realized then that he probably always had a crush on her the day he first met her. It's just that he never knew because, until recently, he was good at restraining his emotions. He could easily fight back the urge to ask her to dance or go out, finding it normal to think that about a pretty girl. He had no troubles having sexual fantasies even but at the end of the day, she was just another target to destroy... until now. He always took these emotions and just put them away, shrugging them off as normal emotions that were unnecessary. That's what his dad taught him anyway. Both he and Cinder always said things like 'don't think, obey/just get it over with'. But now, he couldn't help but to think. He looked back at her. She had curled up int a ball to keep warm.

He thought about putting a blanket on her but noticed that she was dirty and bruised... her condition was suddenly bothering him. He normally wouldn't have done anything but, he went into the kitchen and filled up a warm bucket of water and got a rag. He walked back over and pulled her to the edge of the bed, Yang was too tired to even realize what he was doing. He gently cleaned off some spots of dirt and blood. He also cleaned up the excess of their shared fluids leaking from between her legs. Mercury internally berated himself for not using protection or pulling out but he figured Yang probably wouldn't keep a child resulting from this. Besides, it's not like she'd make him pay child support or dump the tyke on him should she decide to keep it. Soon, he was certain she was a little more clean. He then took out a first aid kit and patched up her wounds. She was still too weak to do much but woke up a little bit and saw him cleaning one of her wounds. Normally, she would have a lot of questions but, she couldn't fight off sleep long enough to even ask. Her body had enough. Mercury noticed she opened her eyes briefly but they almost immediately shut. He looked around for anymore obvious cuts and then put the first aid kit away. He even put one of his tank tops over her to give her some cover. He normally wore it to bed but figured she needed it more for the moment. He then got back onto the bed next to her.

He pulled a blanket over both of them. He stared at her as she slept quietly. She almost looked dead already. He ran his hand over her neck just to make sure she still had a pulse. He then moved his hand to her hair and ran his hand over it gently. He remembered Yang hated it if anyone messed with her hair without permission but he couldn't help but touch it. Her hair was soft and it gleamed beautifully. Still cold, she shivered a little and scooted a little closer to Mercury. He smiled and pulled her against himself. Her hair even smelled good still, too... Lavender shampoo from the smell of it. She awoke briefly, looked up at him but thought better of protesting him holding her like this. She relaxed, resting herself on his chest, not wanting to admit that she kind of liked the feeling of his hand running through her hair. She fell back asleep, troubled by the fact that she kind of liked sleeping like this.

"I could get used to this." he thought.

But the thought pained him. Because there was no way in hell he could. After tonight or until she's able to move again, they will be enemies and unless he wanted to suffer Salem's wrath, he would probably be faced with having to kill her. The thought pained him more than he'd like to admit. Maybe he could convince Salem to let him keep her as a personal pet but he knew Yang would likely rather die than to live like that. He decided he'd figure out some way to allow Yang to live. But before he could think of a realistic idea, he felt his eyes grow heavy and he started to nod off. So he fell asleep with a girl who was his near opposite in his arms.


I think I'll continue this story but still, I think Yang and Mercury are a pair of sort in the show. They are often showed fighting in the biggining scenes, she has gauntlets while he has grieves, she's gold, he's silver, She's, well, Yang and with his last name being black, I think he is yin but instead of naming him that to make it more obvious, he was given the last name Black. Yang is also, in a way, themed after the sun and Mercury is the planet that orbits closest to the sun. I'm not sure if they're just meant to be the perfect enemies or eventually a pair of sort but I noticed these two were equal and opposite kind of... I just hope this doesn't mean Yang will lose her other arm.
