A/N: The Blue Exorcist's anime staff had no business to resurrect Neuhaus's wife and kill them together at the latest episodes… Damn it all! T.T

"Nii-san, are you sure going to be alright?"

"Oh come on Yukio, stop worrying!" Rin grinned. "Classes are continuing just fine! Shura's training is going well and she said I would soon get Kurikara back! Neuhaus sensei and Sir Pheles are in the Academy too, and it's fully protected, so nothing bad is going to happen! Also, we said with the guys that we could go camping…"

"That's what I fear. You and camping together usually means disaster." Yukio sighed exasperated as he carried out a final check of his belongings. "Please nii-san, promise me that you'll stay in the Academy and will create no mess while I'm gone?"

A couple of months had passed since Rin had taken the Vow. In the meanwhile, everybody had learnt the truth about his origin, the Vatican had accepted him but was still rather hesitant, Shura had taken his sword away from him until he could control his flames, and now Yukio was leaving for an important mission. Rin remembered of the Vow only the rare times he'd see and actually take notice of it. It was covered by the school uniform's short sleeve, and seemed like a very cool tattoo like a bracelet high on his arm, so he just dismissed the thought of what it stood for. Neuhaus also acted in class like nothing had ever happened so Rin just concluded everything was a closed chapter. For the time being, he cherished the thought that he'd have all the building by himself with Yukio's departure. He would invite Bon, Shima and Konekomaru over so that they could play video games all night, maybe some time even Izumo and Shiemi for a sleep-over… Rin practically drooled, picturing himself and cute Shiemi cuddled up together. Shiemi was so sweet! And she had really nice boobs… Rin blushed at his perverted thoughts and started rolling on his bed, full of wishful thinking.

Yukio sweat-dropped. "Hey nii-san… I'm not wasting my breath, am I?"

"Uh? Sorry Yukio, you said something?"

He's SO going to mess things up! Yukio had already given up hope. "Nothing, forget it. I'm going." He picked his suitcase up. "Just so I will get a bit of peace; please say that you'll at least try to act your age?"

"I'm only fifteen!"

"Almost sixteen! ...And a bit more mature than that would actually be nice."

"Oh fine, fine!" Rin shouted, but not really irritated. "I promise that I will behave. For real. Happy now?"

"Eh." Yukio made the so-so gesture. But then he kindly smiled. "Nii-san, I'm going now. Take care, okay?"

"You too, Yukio." Rin smiled back. "Be careful." Yukio waved and got out of the room, taking his stuff with him. Rin remained looking at the door for some moments. He had faith in Yukio, but that didn't mean he couldn't worry about his brother, no matter how much of a trained exorcist he might be. Oh well. It was pointless to think about that now. He bounced on the bed. Today was Saturday, he didn't have many things to do, and all of his classmates had gone to their homes. He reached down his bed and grabbed one of his favorite manga. He would just indulge himself in fiction until the day was over.

It must have been approximately an hour afterwards when he heard a knock on his door. He looked up perplexed. No one should be in the academy anymore, at least not someone that had business with him. "Who is it?" He asked, as he approached. In response, the knock was repeated. "I'm coming, I'm… Sensei!" Rin exclaimed surprised as he opened the door and met Neuhaus. "What's wrong?"

"Take a guess." Neuhaus didn't waste any time to grab Rin by the hair. He tightened his fist around the black locks, making sure it hurt the young half-demon.

At first, Rin was plain shocked. Then he got angry. "What the fuck are you doing? Let me go!" He tried swinging a fist towards his attacker. He was even more shocked to discover that his power dropped to zero instantly, managing only a weak tap. He tried again, and again and again, but all attempts failed. Rin couldn't believe his eyes. He always had quite the strength, no need to mention after his powers awoken. "W-What? Why…?" He stuttered, unable to understand.

Neuhaus barely smirked. "Remember this?" With his free hand, he tugged Rin's right sleeve up, revealing the mark of the Vow. "You can do nothing, and I can do anything." He tugged at Rin's hair even more violently than before, and Rin let out a small yelp. "Drag your feet, demon." And with that, he got him out of his room.

Rin twitched at how the roots of his hair were stinging his scalp. "Wait! Where are you taking me?" He still wasn't scared, but he was very angry. "Answer me!" He demanded, trying to free himself from the man's grip. No such luck. His teacher never responded to his calls, until they reached a part of the academy Rin had never stepped foot in. When they reached a certain door, Neuhaus finally let go of his hair, but grabbed his wrist instead. "I said let me go!" Rin tried to yank his hand away, but to no avail.

"I'm going to make use of our deal, Satan's son." Neuhaus finally spoke as he opened the door and practically tossed Rin in. Rin had no time to take in his surroundings, as he had suddenly found himself in the middle of what he would call a living room. Apparently, this was where his teacher was living. Before he could open his mouth, Neuhaus grabbed him by the collar and guided him further into the apartment, finally throwing him into the bedroom. Rin fell on the carpet right beside the bed. He shot up immediately, baring his fangs. He tried calling forth his flames, but they just wouldn't obey him. Neuhaus raised his eyebrow. "What? You're not going to accept the terms? Of course I should have expected it from a demon… Somehow, you don't seem so eager to offer yourself to me anymore."

Rin breathed heavily in order to restrain himself and prevent him from doing anything stupid. Not that he could do anything whatsoever… It had passed a long time since he took the Vow, this was coming to him too sudden, and his instincts for survival were getting the best of him. "Why now?" He spat. "If that's what you were going to do from the start, what took you so long?"

"My terms of agreement, of course." Neuhaus started circling Rin like a shark preparing to snap at his prey. "That and you've caused quite uproar recently. But now that your brother is gone, I don't risk breaking my pact… Do you even remember the Vow?"

Rin used the opportunity of the small talk to calm himself down. Neuhaus wasn't scaring him. But something inside him told him that he should be afraid. He regained his composure and mustered his courage and seriousness. "What are you going to do with me?" He steadily asked.

"Killing you is not such a good idea." Neuhaus informed him. "I may get in trouble for that by Sir Pheles, maybe even by some circles in the Vatican." He leaned in behind Rin to whisper in his ear: "But don't worry. I'm definitely going to do to you the next worst thing there is. I'll make you regret that fucking damned day you were born, you filthy abomination." Rin gritted his teeth, trying to control himself. Mostly because he knew it wouldn't get him anywhere. Neuhaus leaned at the other side of his head, to whisper at his other ear: "Want to guess what that is?"

"You're going to torture me…" Rin realized. He tried gathering up his power. The way things had progressed, only strong willpower would get him through this. Deep down, he knew he wasn't responsible of any of Satan's evil deeds, but he did wish to help all the people Satan had hurt. Now he didn't know what exactly he was doing, or what he should do. Things just happened in a way that trapped him and he just had to bear with it. He just had to be strong…

"No shit Sherlock." Neuhaus scuffed as he came to stand in front of Rin. "Tell me how."

"I'm not playing that fucking game with you. Whatever it is, do it and get it over with." Rin glared at him. He wouldn't let that bastard toy with him as he pleased, not whenever he could prevent it.

Neuhaus couldn't resist. He laughed. "Oh my… You're such a kid after all." He just couldn't stop laughing at that weird form of demon innocence.

"Kid… Hey! What do you mean?" Rin got irritated at the spot.

"You don't have the slightest idea, do you? What's the worst thing next to murder…" Neuhaus laughter ceased. He ran his fingers on Rin's neck, making him shudder. Rin was sure that he'd grab him by the neck and try to strangle him. Instead, his fingers continued to ran down at his stern, until he got a firm grasp of Rin's necktie. He took it off with a mere, strong pull, and held it in his hands. This action didn't confuse Rin as much as the next one.

When his teacher started unbuttoning his white shirt.

"W-What are you doing?"

"What does it look like I'm doing."

"I know, but why does it have to…"

Neuhaus looked at the boy. His face was genuinely perplexed. Not only didn't he understand, he couldn't even imagine what would follow. A pang of guilt shot through him. Maybe he should just stop. Forget about the whole thing. Forget? Forget so easily? Should he forget when the visions of his wife and children when they were tortured and burned to ashes followed him even in his sleep? And now that he had the son of the culprit right in his hands, he should forget? Rage started accumulating inside him all over again. Rin noticed the change of his expression and this time, he started to cringe. He hadn't done anything, so why did his teacher suddenly seem to be so enraged?

Before he could make a move to try to protect himself, Neuhaus tore that white shirt away from his body, turned him around and used his necktie to firmly tie his hands behind his back. Rin didn't resist, he couldn't. But now he was seriously getting scared. He wasn't used to not being able to defend himself or strike back when somebody was coming onto him. Usually, due to his short temper and violent outbursts that originated from his demon nature, he rarely found himself in a totally hopeless situation. When he took that Vow, he had felt sorry for what had happened to Neuhaus and his family, and at the time he thought that he could take away all of his pain by accepting his wrath. Now that the time had come, he had much less courage, because he wasn't the one that decided he should do so at that moment. He tried reminding himself that whatever it was, if it wasn't death, he could take it.

His confusion grew even bigger when Neuhaus tossed him onto the bed, face down, grabbed his legs and started taking off his shoes and his shocks. "What are you doing?" He asked again, he couldn't understand. He had heard about a way of torture called phalanx. You strike with a bat on the soles of the victim. Maybe that was it?

Neuhaus adjusted Rin's body better onto the mattress, and climbed on top of it, straddling him. Rin started catching on what was going on, but this time he chose to refuse to believe it. As his back was facing his teacher, Neuhaus leaned in to place his face exactly next to Rin's. "Let me tell you a story." He whispered in his ear again, and Rin felt hands at the belt of his pants. Pure fear dug his way in. "Remember how I told you my family was burned by your damn father?" The belt was gone, and the older man's hands started working at the buttons. "That's only half part of the story."Buttons were off; he slid his fingers through the fabric supported by the hips. "They were also raped in front of my eyes." With those words and one swift movement, he pulled down both trousers and underwear, leaving Rin naked, for the first time in front of someone else.

Rin tried to grasp what he had just heard, what had just transpired, and what would come to follow. Words stuck at his throat. He felt the other man taking his garments completely off his body, but he couldn't kick his legs to try to stop him, the seal made sure about that. So many things were passing through his mind that he could no longer think. Would he really get raped? How would it feel to get raped? He got dizzy and nauseous. Neuhaus was a guy, he was a guy! Neither was homosexual. Neuhaus was older, much older than him, and on top of everything, he was his teacher! Suddenly all those reasons seemed no longer important. "I-I'm sorry to hear that, but I…" I have nothing to do with this! He inwardly screamed.

Neuhaus flipped him over so that he was lying on his back and his head rested against the pillow. Now they faced each other. He scanned his body with his eyes… eye, whatever, Rin didn't want him to look at him! He felt embarrassed, humiliated, victimized. On his part, Neuhaus couldn't but admire the well-toned body beneath him. And it wasn't just the body. Rin had beautiful black hair, soft skin, alluring blue eyes… and a perfect smile. Satan's son shouldn't be allowed to smile! His rage took over once again, and this time, it was crucial. Smiling when other kids are dead! Satan can't give birth to something this beautiful, that's why his beauty is deceitful! His very existence is a trap, mere trickery! "…You are perfect for my revenge." He said, and then cupped with his hand Rin's abdomen.

That last act sent such shivers through Rin's spine that he couldn't help but whimper. Don't touch me! Don't touch me, don't touch me don't… It felt so intimate… "NO!" He finally screamed. He couldn't just sit there like a whore and open his legs to that man! The hell with the damn Vow! "No! No! Let me go!" He screamed, thrashed and struggled. Neuhaus watched him in amusement, fighting the same futile battle as a fish caught in the net. He placed his hands on Rin's either side and chuckled at his meaningless efforts. "Help… Help, someone!" Rin didn't remember since when he had to feel this desperate. "YUKIO!" He finally screamed on top of his lungs, and then reduced almost to whispering. "Yukio… Help me…"

"He's not here." Neuhaus told him cruelly. "No one is here and nobody will come to save you." He leaned in and kissed Rin's neck almost tenderly, where his artery was, making the half-demon's breath hitch. "'You can do anything you wish with me until you're satisfied'. Your words, Satan's son. Not mine." He continued kissing. "And I'll do something you won't enjoy one bit." He sank his teeth in the skin, but lightly, without tearing it.

Rin turned and hid his face into the pillow, unable to cope. All he had left was plead… "No… no, no, no please!" He closed his eyes and sobbed, as he felt the hand running on his abdomen one again, and then on his thighs. "Please, don't do this to me! Please…"

"Look at me!" Neuhaus grabbed a fistful of Rin's silky black hair and brought his head up towards his, so that they could look each other in the eye. Rin's eyes were scared, shocked, begging. They had that beautiful blue hue… The same blue Satan's flames were when he burned Neuhaus family to crisp. "Look at me when I'm doing this to you, Satan's spawn!"

"Oh… Oh my God no!"

"God?" Neuhaus chuckled. "You think God hears prayers of scum like you?" He grabbed Rin's knees and opened his bare legs widely. Rin whimpered from shame and fear. He had never exposed himself to anyone before, and now there he lay, stark naked and with legs wide open, ready to become an offer to another guy to freely use.

Neuhaus undid his belt and then his zipper. Rin was just staring in terror as his teacher revealed his erected dick in front of him.

"No… It's-it's too big, it can't…"

"Oh it will go in just fine." Neuhaus said as he grabbed Rin's hips and lifted him up to guide his back entrance to his member. "Watch." Then he leant forward and violently buried himself deep into the body of the young boy captured beneath him.

Rin screamed like he had never screamed before. His eyes were instantly filled with tears, and he felt like his brain exploded from pain. So much for worrying about getting raped. His mind erased all thoughts, everything but the pain and the agony it caused. This was pure torture. Soon enough his face was soaked with tears, and still, he kept on screaming. The fact that he knew he couldn't fight back and no one would come to save him just made him throb more from hurt and horror. He could only stare at the lamp on the nightstand, his vision going up and down, up and down, as his body was roughly violated and shoved harshly against the mattress. Body lifted up again so the older man's cock would go in, down for out, in and out, in and out, blood dripping down his thighs, fire licking his insides, it cut him it hurt so much… His screams gradually ceased, he had no strength or pride left. His head fell back on the pillow and Rin just closed his eyes and surrendered to the painful thrusts.

Neuhaus continued raping the boy with all of his anger. He could barely comprehend that Rin's warmth felt amazing against his member. "So tight…" He said, but without really realizing it, just wishing to humiliate Rin more. Rin was warm, soft and deliciously tight indeed, but Neuhaus didn't care. All he cared about was to make Satan's son suffer. Suffer like his loved ones had suffered. He was so indulged in his rage that he didn't understand what he was doing anymore. The boy's legs were wrapped against his waist and yes, they looked beautiful, they felt beautiful, soft skin that was like cream against his hands, and better than anything, Satan's son's face full of tears. The blood had stained the white sheets, underlying dying innocence. Satan's son is no innocent, he reminded himself. He suffers like he deserves. Satan's son is…

Suddenly, he came. He gasped at the sudden, amazing feeling. He couldn't remember how long he had to feel this way, not even if it had ever felt better before when having an orgasm. He clutched Rin's body desperately onto his own, in order to lock himself with the boy as he was overruled by the immense pleasure. For fragments of second he wished he'd remain like this forever. Rin screamed one last time at the sensation of the warm liquid going through his entrance. He didn't want to think what that was, he didn't want to believe what had just happened. A man had just… inside him…

Neuhaus stayed a bit longer inside Rin, breathing heavily before pulling out. He had to marvel the boy's body glistening with sweat, his thighs full of blood and sperm. And on top of that all, Rin's whimpers and sobs were reaching his ears like the finest music. "You are a very good fuck, Satan's son." At those words, Rin hid his face in the pillow and sobbed harder, without being able to control it. Neuhaus got up and zipped his pants, making himself decent and composed like all this first started. He wasted no time and picked a gun from a bag on the floor, turning it towards Rin.

Rin heard the characteristic sound of the gun's safety unlocking. He slowly turned and faced his teacher, his face still wet from the tears the terrible rape had caused. The gun was pointing at his head. All Rin could do was stare at him. He had no voice left to plead. He still wanted his life, but that very life wasn't in his hands anymore.

Neuhaus remained unmoving. Just one little push on the trigger and his revenge would be complete. But that boy on the bed… He looked so pathetic and so beautiful. And if he ended it that moment, then what? He still wasn't satisfied. Far from that. If he killed Rin now, he would lose every way he had to take revenge on Satan. But would it be wise to leave his son in the academy, walking around?

He looked at Rin more. Could that weeping boy cause any trouble for real now? He lowered his gun. Rin closed his eyes and sighed inaudibly from relief.

"Don't think it's over. Don't think even for one moment that this is over, Satan's son." He turned away. "When I come back, you're expected to be gone. And that's just ten minutes. Otherwise, we're going to go at it all over again." He walked out of the door like it was nothing, leaving Rin sink into the stained sheets and his own self-loathing.

Dirty, dirty… This feels so dirty, I'm so dirty! Rin thought in agony, not being able to shake off the feeling of getting fucked. How to pick up the pieces when everything in you just suddenly shuttered?
