Hi there! I'm back with a new smut bdsm chapter for OtoShie. I just want to thank my girlfriend for helping me editing this chapter, and I hope you'll like it.

"Shiena-chan ~"

"Hm?"

"I love you."

Her reaction was instant. Shiena's cheeks immediately turned red. Her overall plain face almost looked pretty when she was blushing. But Otoya had to admit that she was rather cute.

Those simple words were enough to shatter Shiena's resolve and bring her to an obedient and even submissive state. People were so easy to manipulate. Otoya felt no regret in abusing that fact, and Shiena was no exception. She would use those special words whenever she pleased to get what she wants. But she did mean them- she very well did love Shiena… in her own special way.

"I… I love you too."

Otoya smiled sweetly as she gently brushed Shiena's cheek before giving her a soft kiss on the lips- the coup de grace if she still had any resistance left. Her girlfriend let her do as she pleased like a docile girl. Good. Shiena was a girl with a strong personality, she was resilient. But yet, Otoya knew she could tame her, mold her into a true sub, and most of all, her loyal pet- no, she stopped herself- girlfriend was the word she was supposed to be using. Of course. A more sinister smile appeared on her lips at that thought.

"So? Is that a yes?" Otoya asked softly.

Shiena sighed with a resigned look, before smiling weakly.

"Yes," the brunette replied.

This time Otoya didn't stop herself from grinning satisfactorily, beaming with a feeling of victory. She even let herself chuckle as she grabbed both Shiena's shoulders and gazed at her right in the eyes.

"I want you to resist. I want you to fight back. Can you do that for me?"

Shiena looked surprised at first, but then slowly, she nodded with a hesitating expression.

"Y-Yes. I will."

Otoya's grin only grew wider. Her grip on Shiena's shoulders tightened, and she suddenly tripped her over and pinned her to the floor. Otoya didn't want to lose any more time and hurriedly started pulling off Shiena's clothes. It was rather easy to do- Shiena's pajamas were simple and not too hard to simply tear away. She would usually use her scissors here, but she knew her girlfriend wouldn't like it. She easily unbuttoned Shiena's top and removed it while the brunette was struggling. She really looked convincing, which was expected from a girl who was so passionate about theater. Otoya almost thought Shiena was being genuine, but remembered that if she was, she would have said her safeword by now. Otoya grabbed Shiena's bottoms and tried to yank them off, but her girlfriend retaliated by kicking her in the stomach.

Otoya liked this. It remembered her of her past victims and what she did to them. Some of them put up a good fight, and it made things so much more exciting and satisfying. Shiena was pretty feisty, and she was putting a lot of effort into trying to defend herself. But she was just so weak. Otoya could barely believe that this girl was once accepted to enroll in Class Black of all things. She was used to overpowering older women, so someone like Shiena was far from posing any challenge. But she liked it regardless. Using force on Shiena and making her submit herself so completely was quite arousing. And, really, her pathetic attempt of protecting herself was quite adorable.

She managed to remove Shiena's pajama bottoms after some resistance, leaving her girlfriend completely naked. She tried to push her away, but Otoya was faster and grabbed both her hands at the wrists, successfully pinning her to the ground. Otoya used her knees to hold down Shiena's legs, preventing her from kicking again. Her girlfriend continued to struggle, but it was in vain. If she was one of her regular victims, Otoya would have already beat her to submission. But Shiena was precious- she was to be treated with more delicateness. After all, she was the type of toy that could be used more than one time and Otoya knew she had to take care of her property.

Otoya restrained both of Shiena's wrists on the floor while she stretched her free arm to grab something special under the bed- a pair of leather handcuffs she had left there on purpose. Quickly she flipped Shiena over and put her arms behind her back, handcuffing her. Otoya rose up and took the time to admire her handiwork. Shiena was naked and bound on the floor- completely at her mercy- hers to toy with. Truly an exciting sight.

Shiena was wriggling helplessly, but it was no use. She couldn't break free. Otoya giggled in a way that could almost be described as cute, enjoying Shiena's powerless state, just for a moment, before she went to retrieve Shiena's suitcase in the closet- the one containing all her little fun toys. She dropped it on the floor near her girlfriend and kneeled down, taking a long, good look at Shiena. She had stopped her struggling and was now laying there on the floor, looking quite uncertain. Otoya gently stroked Shiena's cheek and leaned in to her, kissing her sweet lips.

"Ouch!"

Otoya recoiled, touching her hand to her lips and feeling a telltale wetness and warmth. Shiena's mouth was tainted with blood. She gazed at her with such defiance in her brown dull eyes. It wasn't the first time Otoya was bitten. Many of her victims tried that, as if it would have changed anything. All they achieved in the end is making their fate even more gruesome. Still, she found it quite entertaining to see how someone can try so desperately to save their own life. It made things far more interesting.

She grinned madly while her blood continued to drip from her, rolling down her chin now. She let forth an insane giggle as she gazed at Shiena, who was beginning to shiver in fear at the sight, much to Otoya's amusement. She fumbled through the suitcase of toys until she found the perfect one to teach Shiena a lesson about keeping your mouth shut. Shiena's frightened eyes excited Otoya so much. She gently grabbed Shiena's chin, pressing on each side of her jaw and forcing her mouth open. Quickly, she shoved a lovely little gag ball into Shiena's mouth and tied it tightly behind her neck. It happened too fast for Shiena to do anything about it except sit there and make cute muffled noises.

"Mmmm, that's better. It really suits you. I didn't know you were a biter, Shiena-chan. That really hurt, you know, you bad girl… I guess I'll just have to punish you~"

Shiena froze and her eyes widened, terrified of what Otoya would do to her. Otoya licked the blood from her injured lip and wiped the rest off with the back of her hand, and then moving to softly pet Shiena's head. She shivered at the contact, and Otoya just loved it. She loved touching her hair- it was just so fluffy and soft. Mhm, just like a tiny little puppy. Her hand sank lower, and she gently brushed her lover's cheek, leaning on her and licking her face clean of any blood. As usual, when it was her own blood it tasted so bitter. She kissed her on the cheek while her hand traced lower and lower. She started by lightly brushing her fingers over Shiena's body, then cupping one of her breasts. Her girlfriend let out a muffled moan that pleased Otoya. She always had such a cute voice.

She started to caress her body knowing that it belonged to her. Shiena was completely and totally hers. She may have a rather plain look, and she was certainly far from being as hot as any of her victims, but Otoya still found her beautiful. She liked to touch her soft and pure skin, to feel her warmth on her hand. She just wanted to play with her now- her sweet and innocent little flower.

Her hand brushed lower still, stroking Shiena's inner thighs and slowly reaching her sex. She started to rub her slit, noticing that she wasn't really wet. Better fix that. With a single finger, she started to tease circles around her clit, which made Shiena utter more weak moans through her gag. Otoya smiled to herself as she went faster, leaning on her girlfriend so she could leave soft kisses on her neck. With her free hand, she fondled one of Shiena's breasts, teasing her nipple with her thumb. She may have small boobs, but they were still soft and fun to play with.

"Mhhhh…"

"Oh? You're starting to like this, aren't you? You naughty, slutty girl. But I've only barely started, just wait until things get real."

Otoya removed her hands and pulled back a little. Looking at her hand, she was satisfied to see cum on her fingers. She licked it up greedily, taking her time to savour the taste of her girlfriend's precious love juice. When her fingers were completely clean, she turned and started rummaging through her collection of toys once more, running her hands over them all in anticipation before finally opting for two of them. A mischievous smile appeared on her lips as she took them and brought her attention back to the girl on the ground in front of her. She took the time to stare at her girlfriend in the eyes. Those brown eyes that never lied, this truthful gaze that was the mirror of Shiena's soul. It was so pretty, so pure- an eternal beauty that will never fade.

It was time to shut them down.

Swiftly, Otoya tied up a firm band of cloth around Shiena's head. Shiena, of course, cried out in surprise, her vision suddenly stolen from her. Otoya admired her handiwork, gazing up and down her naked, bound, gagged and blindfolded girlfriend. Such an erotic sight. There was something especially exciting with the fact Shiena was totally consenting to all of this. She trusted her, she was loyal to her, she belonged to her. Otoya ran a possessive hand up and down Shiena's chest while flipping on a switch for an easily recognizable vibrator Otoya had used on her once before. Otoya grew amused watching Shiena get so nervous at the sound.

"Oh, you remember this, don't you~? If that's the case, you must have a pretty clear idea of what's gonna happen next. Too bad you won't be able to see or say anything, heehee~"

Otoya slowly brought the egg vibrator closer to Shiena, savoring the feeling of watching her girlfriend wriggle helplessly with apprehension. She pressed the toy on Shiena's cheek, eliciting a confused, muffled groan from her. Otoya chuckled to herself, moving the egg down her, over her jaw, past her neck, and along her collarbone. It reminded her when she used to run her scissors all over women's bodies, the blades slowly cutting their skin and letting their blood flow… Even if she kind of missed that, she didn't regret her choice. Playing with Shiena this way was fun too.

When the egg brushed against Shiena's breast, Otoya took her time running it in circles around it, before finally pushing it hard against her nipple. Shiena's reaction was instant- stifled moans pushing forth- while Otoya simply smiled and continued on. She knew that her girlfriend's nipples were particularly sensitive and she never missed an occasion to play with them. She was pleased to see how erect they were. She switched nipples, garnering more moans as both of Shiena's breasts had their share of attention. Shiena had started to rub her knees together feverishly, and Otoya instantly took note. As if they were communicating nonverbally, Otoya understood her request, sinking lower and ghosting along Shiena's belly until she reached her thigh. The tickling vibrations over her body made Shiena shudder in anticipation of what was to come. Otoya stopped before reaching Shiena's sex, her grin only growing wider. She could feel how eager her girlfriend was, how much she was craving to be touched there. Her pussy was dripping cum down her thighs. Otoya decided to satisfy her carnal need and pressed the toy on her clit hard.

Shiena immediately moaned loudly, almost like she was screaming. Ah, music to Otoya's ears. When she pulled the vibrator back, Shiena was gasping deeply. Before she could even catch her breath, Otoya pressed it against her again. After a moment, she released it, and then pushed it in once more. Shiena was twitching and hardily panting through her gag, almost looking like she was in pain. Otoya grinned at the thought and repeated the cycle again, and once more after that- never the same amount of time each round so that Shiena wouldn't get used to it. She was moaning powerfully and quite loudly in spite of the gag.

An idea entered Otoya's mind. Yes, something she could do to make herself pleased like she hadn't ever done with Shiena. In the meantime, she pushed the egg into Shiena's slit- eliciting, of course, another deep moan of satisfaction from her. While she was busy with that, Otoya grabbed a special something from that case of hers- a pair of noise-cancelling headphones. Quickly, she fitted them onto her oh-so-willing girlfriend.

"Shiena-chan, can you hear me?" she asked playfully.

Her girlfriend didn't seem to respond, but Otoya wanted to be sure.

"I'm going to kill you, Shiena," she said coldly.

There was no specific reaction of fear coming from Shiena, and she didn't snap her fingers to show that she wanted to stop, either. Looks like she really was deaf.

Otoya beamed with satisfaction as she rose up and sat on the bed, enjoying the view of Shiena desperately wriggling on the floor while moaning.

This sight was truly arousing. Otoya could feel her own cunt getting wet. She pulled off her shirt and started to fondle her breasts. She groped them and played with her nipples as she continued to watch Shiena on the floor. Her girlfriend was squirming- moaning from pleasure and her legs shaking. It was cute how helpless she was, and above all, it was hot. While she groped herself, her other hand dove lower. She slipped it in her panties and started tenderly rubbing her pussy. Touching her swollen clit forced out gasps and involuntary panting from her. She never felt so excited just by touching herself before. Her sex was all wet and warm right now thanks to Shiena. She continued to masturbate at the sight of her girlfriend shifting around on the floor in such a pitiful yet erotic way. Ah, the things she would like to do to her…

… But what was stopping her? Shiena was at her mercy right now- she couldn't do anything to stop her. Touching herself wasn't enough, no, she needed Shiena. She needed to fuck her.

Otoya rose up, dropping her skirt and panties, and descended upon her girlfriend. She sat close to her, quickly opening Shiena's legs and pressing their pussies together forcefully. Otoya could feel a faint vibration on her sex when she pushed against her, their clits rubbing against each other all the while. Shiena was moaning louder through her gag, exciting Otoya just as much. Shiena was deprived from her senses and her freedom- all she could do now was feel. It made Otoya feel so powerful, and she was taking great pleasure in completely dominating Shiena. It reminded her of when she fucked her victims, whether they wanted it or not, before brutally killing them.

"Shiena, I love this! I feels like I'm raping you! It's just like when I raped all those women! But you… you want this. What a slut you are. It just makes me want to fuck you even harder and utterly violate you! You're mine to take whenever I want- you belong to me. If I want to rape you, I can, if I want to cut you, I can, and if I want to kill you, I can too! Ah, fuck, I love you so much!"

Otoya was moving harder and faster, groping Shiena's all over. Hers, it was all hers. Their clits were hard and giving each other love- their pussies dripping wet and their cum mixing together. Otoya was moaning with no restraint, only focusing on her lustful desire and the wonderful feeling on her sex. Shiena suddenly started convulsing and let out a powerful moan, her muscles all tensing up. Just as quickly as it started, it ended, and she went completely limp. A lovely orgasm, indeed, but it didn't mean Otoya would stop. She wouldn't stop until she came, too. Feeling she was close, she ramped up the pace, feeling the pleasant pressure in her hips growing and growing.

"Mhhhh… Shiena… I-I'm about… to come… oh god- ahhhh!"

Otoya threw forth one last thrust with her hips came, the sweet pleasure of an orgasm overtaking her entire body. She nearly screamed in doing so, her moans strong and loud. Euphoria overtook her- pleasant, relaxing euphoria that made her feel like she could just lay down and instantly fall asleep. But she knew it wasn't over. She sighed and steadied her panting to catch her breath, pulling the vibrator from Shiena's sex and switching it off. Shiena still laid there, unresponsive, though.

A little bit concerned, Otoya softly pulled off Shiena's headphones, untying her blindfold, unlocking her handcuffs and unclipping her gag while she was at it.

"Shiena-chan?"

No response. The brunette was heaving and gasping on the floor, shivering. Well, at least she was clearly physically okay. Otoya slipped her arms under Shiena and rose up, carrying her to bed. She laid close next to her and pulled the blanket over them, gently petting Shiena's head and stroking her hair.

"Shhh, it's okay Shiena-chan. It's over now. You're safe now, with me."

Otoya started caressing Shiena's arms and kissing over her face- but before she could do any more, Shiena turned and wrapped her arms around Otoya's waist, snuggling against her closely.

"O-Otoya… I love you."

It must have felt odd and contradictory to say those words to a serial killer, but yet, she still felt great satisfaction in hearing it and couldn't help but smirk.

"I love you too."

Otoya hugged Shiena tight and rubbed her back, cuddling together with her under the blanket. It was a peaceful and relaxing moment after the intense sex they had. Otoya really enjoyed it, but she knew she may have went too far this time. She made a mental note to give Shiena a bit of a break and work on being particularly soft and kind with her so she can eventually do it again. It was all an investment for her own pleasure.

She heard a soft snore coming from Shiena and gave her one last kiss on her forehead before closing her eyes, falling asleep in turn.

Well, I hope you enjoyed this, and thanks for reading!
