Hi there! If you are familiar with my other fic Bully & Bullied, this fic was at first a chapter of B&B, but I decided to turn it into its own fanfic. From now own, I'll use this fic to post smut OtoShie chapters, mostly BDSM ones. Even if this fic is connected to B&B (it remains in the same universe), you don't need to have read B&B to understand it. The only thing you need to know is that Shiena was tired to find snuff porn in her history search so she's trying to try initiating Otoya to something more healthy to satisfy her need for dominance.

ps: In B&B I establish that Otoya is a psychopath and has erotophonophilia (a paraphilia also known as lust murder), so keep that in mind when reading this fic.


Shiena wondered if she had made a terrible mistake. She kept wondering that while Otoya was striping her naked and handcuffing her with leather handcuffs, as well as putting a collar around her neck, but somehow, despite her worries, she had let psychopathic girlfriend do this. After all, the brunette fully consented to this.

"I promise that I'll take that seriously!" Otoya had claimed sooner. "I made a lot of researches, I know fully how it works. I'll be good and respect the rules, so you don't have to worry."

Lying on her bed, fully naked and her hand handcuffed behind her back, Shiena continued to wonder if it was really a good idea to initiate Otoya to BDSM. Sure, since Shiena told her about it, Otoya's behaviour was less erratic, she had stopped to watch suspicious porn, and she was less grumpy. The latter had gone back to her usual easy-going and cheerful persona. But still, was it really safe to trust a serial killer, as well as a psychopath? Absolutely not. But perhaps it was safer than letting the said psychopath who usually got sexual pleasure by killing being more and more sexually frustrated. That was why Shiena was ready to try this, because either way, she wasn't safe. She was already not safe since the day she had agreed to let Otoya live with her and then started to date her. Shiena made that choice while knowing what kind of person Otoya was, and thus she had to accept the consequences of her choices.

Still, she couldn't help but be afraid. Let's not forget that she was currently naked and bound, helpless and completely at the mercy of a psychopathic serial killer who had killed at least 30 people. Anyone would be terrified in her situation, and it was worst since she knew that most of Otoya's victims must have been in a similar situation as her right now. And the worst was, it wasn't the first time Shiena was in a similar situation, and last time it resulted in torture and rape. Really, one had to have a death wish to do something like that. Looked like Shiena had low value for her own life. But right now, it was probably too late to question her life choices.

"Otoya, you...don't forget about the rules. Do you remember the safe words?"

"Um? Oh, it's...'bullying' for slowing down, and 'veggies' to stop, right?"

Shiena chose bullying as her safe word for if she wanted Otoya to slow down without stopping, because she knew that if she feels the need to say that word, it would be because she's uncomfortable. She chose veggies to stop because saying that word was a huge turn off to her, since she hated vegetables.

"Yes. And if I'm not able to talk, I'll snap my finger. Understood?"

"Yep! Don't worry Shiena-chan, you can trust me!"

Somehow, Shiena really doubted those words, but she had the feeling that it may be too late to go back now.

"Well, it's time to begin now. Until now, you no longer have rights. You're now my propriety."

Shiena noticed a sudden change in Otoya's vibe. The latter was still smiling, but she seemed colder, threatening, lustful, almost like a predator, similar to a cat who was about to play with its food. This thought didn't comfort Shiena at all and she even began to shiver in fear.


Otoya already felt some arousal. To see Shiena like that, so helpless and vulnerable, to know that she had all the power over her body, it was truly exciting for Otoya. It was like the brunette's life was in her hands, which was a wonderful feeling. Otoya felt like a snake who had captured an adorable little mouse, she could just strangle her slowly to death and eat her…

"No no, Shiena-chan isn't like all those empty girls with only a pretty face. She has a pure heart, she's an eternal blooming flower. I have to keep her alive and not damage her too much. Otherwise, what would be the point of keeping a flower whose petals are all damaged? It would be such a waste. I just need to play with her gently."

Otoya suddenly noticed that Shiena was shivering. She had seen enough people fearing for their life to know that it was probably why her girlfriend was shaking, which Otoya found strange. Wasn't she the one who wanted to do this? Wasn't BDSM her kink? Well, even if it was, Otoya couldn't blame her to be afraid right now. Even Otoya was surprised that Shiena accepted to do this with her. But she was also happy, because it meant that the brunette most trust and love her. To know that she was attached to her comforted Otoya, she felt that she had more control over Shiena, and that this way, she had more chances to keep her by her side and even possessed her.

And, seeing Shiena was afraid and shivering was quite turned on for Otoya. It made her feel even more powerful, that she was dominating her both mentally and physically.

Otoya removed some of her clothes, only keeping her underwears. She then sat on the bed near Shiena, contemplating her frightened girlfriend with lust and thinking about what she should do.

"Ah, there are so many options in BDSM, what should I do? Whip her? Punish her? Humiliate her? Should I act like a sadist, a dominant, a master? So many choices…"

As she continued to think, Otoya had started to pet Shiena's head softly. When she heard her girlfriend purred under her contact, Otoya finally realized what she should do.

"I get it. I should just act as I always do with Shiena-chan, I should act natural."

Delicately, Otoya grabbed Shiena and brought her on her laps, still keeping her lying. The brunette's head was now resting on Otoya's thighs and she was showing her her back. Otoya continued to stroke Shiena's hair, the feeling of their fluffiness against her skin was quite pleasant, she could feel it on her laps and hand. She then went lower, now stroking Shiena's shoulder softly, then her arm, before she went for her belly. Shiena let out a slight moan, she must be sensitive there. Otoya found that reaction adorable and wanted to see more. She continued to pet Shiena's tummy, which made the latter moaned weakly, as well as wriggling. Otoya concluded that she must be ticklish there.

"How cute ~"

She then put her hand on Shiena's chest, cupping one of her breasts. As usual, Shiena's skin was soft to touch. She gently fondled it and teased her nipple. This time, Shiena moaned a little bit louder. Otoya even noticed that her girlfriend's legs were shaking a little, she was rubbing her thighs together. That sight made Otoya's smile with amusement and satisfaction.

"Aww, she's starting to get aroused, how adorable."

Otoya then removed her hand and began to caress Shiena's upper back instead, beginning with her shoulder blades, to then delicately tracing her spine, going down, then massaging her lower back. Shiena purred in a satisfied way. Otoya continued to caress her there for a couple of seconds, before she finally reach her ass. She suddenly grabbed one of Shiena's butt cheek and skeezed it, which made the brunette uttered a surprised moan that Otoya found pleasing to hear. The serial killer took the time to admire her girlfriend's ass. She had a cute butt, just as soft as the rest of her body, and even more white like porcelaine. Such a perfect white skin, with no mark on it, it was truly a beautiful sight for Otoya, it really excited her…

...so much that she couldn't help but want to see it becoming red like blood.

On that thought, Otoya suddenly slapped Shiena's butt, which caused the latter to let out a surprised, as well as pained, cry.

"O-Otoya!?" Shiena exclaimed with a voice that sounded both shocked and offended.

But Otoya didn't mind Shiena's protest. She glanced at her ass and noticed a slight red mark, the mark of her hand when she slapped her. Otoya found it pretty, she liked to see the handprint on Shiena's butt, a red mark on a perfectly white ass. It was like she had mark her territory, let her signature on her belonging. And she wanted to see more of it.

She flipped Shiena on her belly to have a better access to her butt. But thanks to that, Shiena had now her face lying on Otoya's laps. Otoya could feel her warm breath on her bare skin, near her crotch. The serial killer let out a weak gasp of pleasure. If she let Shiena's face there, she'll most likely get too aroused to control herself. If she wanted to make the pleasure last for a long time, she needed to do something about that. Otoya grabbed Shiena under her her shoulders and dragged a little so it would be now her stomach that was resting on her laps. Otoya put on hand on Shiena's head, patting it, as well as making sure the brunette won't be able to struggle. She then raised her other hand and slapped once again Shiena's ass.

"Ouch!" Shiena complained with a pained voice.

But it didn't stop Otoya at all, on the contrary, hearing Shiena's expressing pain only excited her more. She continued to mercilessly spank her girlfriend's ass, leaving multiple hand marks on her butt.

"Otoya, stop! Please, it hurts…"

Otoya took a brief moment to think about it. She was really enjoying herself right now, but Shiena was asking her to stop...yet, she didn't use any safe words, so the serial killer assumed it was part of the game.

"Um, I'm not feeling like stopping," Otoya replied pitilessly.

And so, she continued to spank her girlfriend with a lot of enthusiasm, putting even more strength in her slaps. Shiena's ass was almost all covered with her handprints, there was no doubt in Otoya's mind about to whom the brunette belonged to. Shiena began to let out some weak sob, but Otoya didn't mind them, thinking that since BDSM was Shiena's kink she must like it. As she continued to spank her, Otoya saw her butt slowly turning red, there was barely any white now. It was almost like she had covered it with blood. It was so arousing, so much that Otoya began to lost her composure. Her other hand stopped petting Shiena's head and went deeper in her hair, almost pulling them, as she continued to spank her with strength.

"P-Please, Otoya...stop...bullying me!"

It took few seconds for Otoya to realize that Shiena used one of her safe words, the one that meant she was uncomfortable with something and wanted to slow down. Upon this realization, Otoya stopped. Not because she felt bad for Shiena, but because she knew her girlfriend would be mad if she continued, which could ruin their relationship. Otoya would have like to continue spanking her, but the pleasure she got as a couple with Shiena worth more than some slaps on the butt. Anyway, Shiena's ass was all red and full of hand marks, which was a satisfying result for Otoya.

Otoya noticed that her girlfriend was still sobbing and had start to shiver again. Delicately, Otoya flipped Shiena, lying her on her back. The brunette had tears in her eyes that had began to flow on her cheeks. Otoya found that teary eyes were pretty on girls, it made their eyes looked like they are sparkling, making them even more beautiful. Shiena was not different from them regarding this point. But right now, Shiena wasn't just sobbing, the muscle of her face when stiff, a clear indicator that she was really in pain. Somehow, Otoya didn't like to see that kind of expression on her face. She liked it though on other girls' face, because those one were just ladies with a pretty face, so seeing their pretty face being twisted by pain was pleasant for Otoya, she felt like she could see their true self that way, see through their mask of beauty. But such a thing was useless with Shiena. The brunette was wearing no mask, her face was already her true self, Otoya could clearly see her pure heart, her eternal beauty, in her eyes. And pain was tainting it.

"Hehe, I might have gone too far, sorry," Otoya said. "No need to cry anymore, because it's not pain that I'll inflict you, but pleasure."

Otoya approached her face from Shiena's and licked her tears, taking the time to taste and savour them. Truly, most fluid from Shiena's taste good, her tears, her blood, her love juice. Then, she gently grabbed her chin and softly kissed her on the lips, before she introduced her tongue inside of her mouth. She then went from her neck and left some soft kisses on her skin, before sucking on her flesh. Shiena let out weak moans of pleasure, and Otoya went for her honeypot. First, she stroked Shiena's thighs, and realized that something wet had flown on them. When she finally touched her pussy, it confirmed Otoya's doubt.

"Haha, Shiena-chan, you're already so wet! You liked to be spanked, don't you? You naughty girl ~"

Shiena immediately blushed in shame and even looked offended.

"N-No! I didn't! It has nothing to do with this…!" Shiena protested, flustered.

"Eh? Then, what's that?" Otoya asked with an innocence expression, showing her wet fingers.

Shiena didn't answer, looking away with an embarrassed expression, which made Otoya smirked with satisfaction.

"Well well, what a pervert you are, Shiena-chan. Getting all wet because you were spanked," Otoya mocked.

"Shut up! I'm not the pervert here, you're the one who gets aroused by spanking me, just as you get off by kil…"

Otoya didn't let her finish her sentence that she shoved her wet fingers inside of Shiena's mouth.

"Tss-tss, bad girl,you're lying. Taste it by yourself, taste how lewd you are. What you're tasting in your mouth is the proof that you're the truth pervert here, getting all excited because you got spanked by a serial killer."

Shiena tried to get her fingers out of her mouth, but Otoya immediately grabbed her jaw and forced her mouth then rubbed her fingers on Shiena's tongue, making sure her girlfriend could taste her own love juice. When her fingers were clean, she removed them, but she still continued to hold her chin.

"See? That's what a masochist naughty girl tastes like…"

"No, that's how a normal aroused pussy taste like," Shiena dared to reply.

"But to be aroused that way after being spanking, it's the proof you are indeed a lewd girl."

"You're wrong, it's because of the way you touched me before…"

Otoya suddenly put her hand on Shiena's mouth, forcing her to shut up. She then reached one again Shiena's sex and began to finger her. The brunette let out some muffled moan. Otoya was rubbing her clit at a fast pace and Shiena's hips were shaking, showing that she would probably not last long.

"Uh, you're still lying. It's not good to lie, you should admire your own perversion. After all, you're the one who is interested in BDSM. Since you are acting like a bad girl, you need to be punished, Shiena-chan ~"

As she said that, Otoya suddenly stopped to touch pussy and laid her on the bed. Her girlfriend glared at her with confusion.

"Why...why did you stop? I was close…," Shiena complained.

"Well, it wouldn't be a punishment if you like it, right?"

Otoya rose up, to go retrieve something in the suitcase full of BDSM accessories. When she found what she was looking for, she went back to Shiena, who was glaring at her with worries, which pleased the serial killer.

"Haha, you look so afraid, how cute. But no need to worry, it's not going to hurt you," Otoya said as she showed to Shiena what she had retrieved.

It was a blindfold. But despite its rather harmless look, Shiena still looked only managed to excite Otoya more.

"What...what are you doing to do it this?" Shiena asked with a shaky voice.

"Eh? Isn't obvious? Blindfold you, duh. Covering up you eyes."

"But...why? What are you doing to do to me...when I won't be able to see?"

Otoya didn't reply to this question, simply smiling, enjoying the fear she could see in Shiena's eyes. She took the time to appreciate that scared look, before she finally blindfolded her girlfriend. Then, Otoya removed her underwears and laid on the bed, next to Shiena. She then grabbed the brunette's waist and brought her on top of her, much to Shiena's confusion.

"O-Otoya, what are you doing-"

"Letting you 'top' me. But, even if you're physically on top of me, you're still the bottom here," Otoya mocked. "As a punishment, you're going to make me come while you're bound and blinded."

"Eh!? How am I supposed to do that…?"

Otoya suddenly grabbed Shiena's chin, then gently stroke her lips.

"Well, you have a mouth, so what about you put it to good use? And I'm sure you can use it to guide yourself. After all, you're a smart girl, I'm sure you can be quite resourceful if you want. And don't go right on my pussy please, take your time. I want to enjoy your naughty self desperately pleasuring me."

Shiena blushed from what appeared to be embarrassment. She then fully laid on Otoya and her face rest on her shoulder. Otoya could feel Shiena's breath on her neck, which was already enough to arouse her. She couldn't way to discover how she will feel when Shiena will actually be doing something.

A shy tongue began to lick Otoya's neck. Shiena really seemed to be trying to determine which part of her girlfriend's body she was near. Without the use of her eyes and hands, the brunette had to rely on other parts of her body. And Otoya knew she would most certainly enjoy the sight of it.

Shiena then reached her collarbones and out of the blue, nibbled them. She wasn't biting her, but the sudden feeling of Shiena's teeth against her skin made Otoya's gasp in surprise. Not that it displeased her, Otoya didn't try to make her girlfriend stop. Somehow, she found Shiena's behaviour adorable, like a kitten trying to bit her. This comparison became more apparent when the brunette began to rub her cheek on Otoya's chest, just like a cat showing its affection. Really, that image was really adorable and even...strangely arousing. She really had the feeling that right now, Shiena was a little fluffy animal, completely under her control, at the mercy of Otoya's desire, and full of affection towards her. The perfect type of partner for someone like Otoya.

Then she realized that Shiena's behaviour was most likely because she was trying to determine which part of Otoya's body she was at. Still, Otoya viewed her as a cute kitten she couldn't wait to play with. She could feel Shiena's soft cheek rubbing against her chest, as well as her fluffy hair that was slightly touching her breasts, and even her nipples. Otoya began to feel a rush of heat between her legs, a jolt of pleasure, followed by a wet sensation. Yep, there was no doubt anymore. She was truly aroused.

Then, as she continued to rub her face on Otoya's chest, Shiena's nose suddenly touched one of the serial killer's nipple. Otoya couldn't help but letting out a slight moan she couldn't repress. A slight smile appeared on Shiena's lips. It looked like she was proud of herself to have made Otoya's moan. Otoya wasn't sure if she liked to see that, but at the same time, a kitten proud of herself to have done something good was kind of cute, and most importantly, made Otoya felt like she was truly controlling her girlfriend.

Shiena then stuck out her tongue and began to lick Otoya's nipple. Otoya never considered herself as sensitive there, she never felt any pleasure by being stimulated there. But this time, it was different. She wasn't being licked by anymore, but by Shiena, her eternal blooming flower, the most beautiful thing to her. Just the thought of this undying beauty licking her, putting effort to please her, it was truly exciting for Otoya. When Shiena suddenly sucked on her nipple, Otoya uttered another moan of pleasure, and felt more jolt of pleasure on her crotch. When Shiena suddenly did the same with her other nipple, Otoya's felt like her clit was pulsating with anticipation. She couldn't resist anymore, she needed to feel Shiena's tongue down there.

Without talking, Otoya made Shiena understood what she wanted by simply slightly pushing her head to make her go lower, but not too fast. Otoya may be really excited, she still didn't want it to be too quick, but neither too slow. She was the type of person who could easily be bored if she lost interest in something, and she didn't want that to happen now.

Following Otoya's silent instruction, Shiena began to go down, but not without leaving a lick from her chest to her belly. It made Otoya shivered a little, more and more hype and excited for what was about to happen. Shiena finally reached her upper body and was now between her girlfriend's brunette did the same she did when she was near Otoya's chest, which was to rub her face. This time, it was against Otoya's thighs. This time, it was hard for Otoya to resist the urge to just grab Shiena's hair and brought her by force on her sex. Somehow, Otoya managed to keep her hands far from her girlfriend. Between her legs, Shiena was still rubbing her face, nibbling sometimes, licking and even leaving some soft kisses. All of this near her sex, but without touching it. But Otoya didn't want to ask her to, to show her how desperate she was. It wouldn't be worthy of a dom to plead her sub, it had to be the opposite. The sub was the one who should desire to please her dom. But still, Otoya was really about to lose control if Shiena didn't go there soon...

It finally happened. She felt a tongue suddenly licking her slit. A shy and nervous tongue. Otoya uttered a weak moan, which seemed to have given some encouragement to Shiena, since she continued to lick her, this time with more assurance. She thoroughly licked Otoya's pussy, licking everywhere, like she didn't want to miss anything. Shiena's fluffy hair brushing against her thighs was ticklishly pleasant, which only made her even more sensitive and turned on.

Then, Shiena's tongue reached the most sensitive area of her pussy: her clit. This time, Otoya couldn't remain silent. She moaned louder and even talked.

"Y-Yes, there. You got the right spot, continue...there," Otoya mumbled between two moans.

Without saying anything, Shiena obeyed, much to Otoya's pleasure. Her girlfriend kept licking her clit with what appeared to be determination, which flattered Otoya. Following her instinct, she couldn't help but pet Shiena's head. Her fluffy hair, so pleasant to stroke, where just too tempting.

"Um yes, yes continue like that, it...it feels great! You're such a good girl, Shiena-chan."

Shiena then sucked on her clit, which was too much for Otoya. She wouldn't be able to last longer, or to keep all her composure. She grabbed Shiena's hair, but not enough to pull them. Just enough to refrain her girlfriend from moving. Until she comes, the other girl wasn't allowed to leave her pussy.

"C-Continue like that, I'm close to...yes, I...I'm gonna come!"

Right after she said that, Otoya felt a strong and pleasant pressure in her pussy, she could feel her muscle stiffed under the powerful orgasm she had, as she moaned without any restraint. As she reached her climax, she slightly scratched Shiena's scalp with her nails. But since the brunette didn't complain, it mustn't have hurt too much.

Otoya's body became limp as she began to pant to catch up her breath. It had been one of the most strong orgasms, if it wasn't the strongest, she even had. It had been as intense as those she had by killing, even better, since the pleasure was both physical and mental. Otoya was able to come with Shiena, but it had never been as strong as right now. It was thanks to her recent climax that Otoya realized that she had been right to keep Shiena alive, because the pleasure she had with her was unique and could last way longer than with any of her victims.

A sudden voice drew Otoya out from her blissful dizziness.

"O-Otoya...was it good?" Shiena nervously asked.

The serial killer opened her eyes and discovered that her girlfriend was still between her legs, her head resting on one of her thighs. Really, this view of a blindfolded and bound Shiena near her sex and blushing was just too arousing, even if Otoya just came. Otoya was far from being over with that BDSM seance, this exciting sight had awoken her inner beast.

Otoya sat up slowly so Shiena's head would still be resting on her thigh.

"Yes, it was wonderful. Thanks Shiena-chan, you did a good job," Otoya said softly as she gently patted her girlfriend's head.

Shiena smiled weakly, and she looked genuinely happy by Otoya's response, which made the latter felt even more flattered. Gosh, the brunette was just too cute right now, lying between her thighs, with her innocence and honestly, so pure…

So much cute that this time, Otoya couldn't help but want to rough her up.

Otoya stretched her hand to reach another accessory she had let near the bed and then, she suddenly grabbed Shiena and flipped her over, to make her lie on her belly. Her girlfriend let out a cry of surprise, not expecting that. Then, Otoya grabbed her hips and forced her to raise it. Shiena had now her chest and face lying on the bed, while her bottom was raised. This way, Otoya could have a full view of her butt and pussy. Otoya's red hand marks were still visible on Shiena's ass, much to her pleasure.

"Otoya!? What...what are you doing?!"

"Well, since you made me come in such a wonderful way, I think it's time that I repay the favour, isn't?" Otoya began to say as she brushed Shiena's slit, which made the latter gasp in pleasure. "And from what I see, you're still quite wet. Did you enjoy that much to eat me out? Just like I said earlier, you're a naughty girl ~"

"Sh-shut up…"

"Uh? How rude. I see that you're also vulgar. That's not good, Shiena-chan. You had been such a good girl but now you're acting as a bad one. Um, what should I do then? You deserve a reward as well as a punishment now. Ah I know. I just have to fuck you senseless."

"What-"

But before Shiena could continue talking, Otoya suddenly forced something inside her mouth and tied it behind her neck. It was a red gag ball, gagging Shiena.

"Shhh. Since you're not using your mouth in a productive way, you are no longer allowed to use it. Anyway, rude girls should remain silent."

Shiena tried to protest, but all that could come out from her mouth was muffled noises. Otoya really liked how a girl sounded while being gagged. Such a pretty melody, especially when she was either screaming, crying or moaning. That was why Otoya almost always gagged her victims at some point, to be able to enjoy what sounded like music to her ears. And also because hearing them begged for their life and ask her to stop usually become annoying to hear after a while. It may be fun at first, but hearing them too long was quite boring and ruining the mood, since it was always the same things they said: "Please stop, don't do that, don't kill, etc...". Otoya much preferred to hear them cry in pain rather than talking.

Otoya glanced at Shiena's hands. The brunette didn't seem to be trying to snap her fingers, which should mean that she was in fact okay with that. Not that Otoya really cared, but she wouldn't want to do something that would make her girlfriend angry at her.

Slowly, Otoya began to rub her index against Shiena's slit. It wasn't enough fast to fully stimulate her, but it was still enough to make her girlfriend uttered some muffled weak moans.

"Well well, but you're liking it. You like to be touched like that as you're bound, gagged and blindfolded uh...you perverted girl."

Shiena shouted behind her gag what was probably insults or protestations, but no word could come out from her mouth, only muffled noises, much to Otoya's satisfaction. She then teased Shiena's clit, but she did it so slowly that there was no way the brunette could feel any real pleasure. To confirm it, Shiena's moans sounded more from pain than pleasure, like it was painful for her to bear with that cruel teasing, like she was craving for real sexual stimulations.

Then, Otoya suddenly moved her fingers faster, and Shiena moaned louder, this time from pleasure. But Otoya didn't continue long, she quickly went back to stimulate her slowly. Then she went faster again for a couple of seconds, and then slow down. The serial killer was making sure that Shiena wouldn't get used to her pace and that she couldn't reach the climax. Not now.

The sound that came out from Shiena's mouth seemed to be a mix of moans and sobs. A truly wonderful sound to hear, and she was still not snapping her fingers. So Otoya felt no obligation to stop this sexual torture, but she was beginning to worry a little bit that Shiena might snap her fingers if she continued too long. Still, Otoya wanted to keep her power over her girlfriend.

"You want to come, don't you? Then, show it to me, show me how desperate you are, how much you want me to make you come. Raise your butt more, so I can see how much you like being touched by me."

Surprisingly, it didn't take long for Shiena to obey and raised her butt higher. She must be really desperate to come, enough to prefer that over her pride. Otoya really felt powerful, like she had total control over her girlfriend's pleasure. It made her even more feel like Shiena belonged to her and that her sexuality was up to Otoya's desire.

"Haha, so lewd. Very well then, I shall make you come, since you're such an obedient girl."

As she said that, Otoya suddenly penetrated Shiena's pussy with two fingers. Shiena's reaction was instantaneous, she let out a strong moan, as her hips began to shake. She was even trying to push her pussy against Otoya's fingers, which made the latter felt proud of herself to be able to make Shiena felt that way. Otoya then laid her chest on her girlfriend's back and smelt her hair, getting intoxicated by her scent, which only made her more excited. She then brushed her fluffy hair away so she could have access to her upper back. Otoya began by kissing Shiena's shoulder blades, then she suddenly bite her. Not enough deep to make her bleed, but enough to leave a mark. The brunette let out a surprised and pain cry, mixed with moans of pleasure since Otoya was still penetrating her. The serial killer really liked how her girlfriend sounded.

Otoya then fondle one of Shiena's breasts and teased her nipple, before pinching it. Once again, Shiena's pained moan was mixed with those of pleasure. Feeling that it was time to finish her, Otoya removed her fingers to go rub her clit at great speed, while still pinching her nipple. Shiena wasn't moaning anymore, she was screaming in pleasure. Then, the brunette's body suddenly became stiff, before immediately felt limp. Otoya understood that her girlfriend must have come. She continued to rub her clit for a moment, but she realized soon that Shiena was barely reacting anymore. Otoya stopped and let Shiena fell on the bed.

Seeing that Shiena was heavily breathing by her nose like she was trying to catch her breath, Otoya removed her gag so she could more easily breath. As soon as she removed the red ball, Shiena took a deep breath, and then mumbled something.

"V...Veggies…"

Otoya froze for a moment when she heard Shiena's safeword. Should she stop? Probably, otherwise Shiena would get pissed off. Anyway, Otoya was also exhausted by her recent orgasm and the energy she put to make Shiena's come.

"Well, it was fun," Otoya thought with a smirk of satisfaction, before she suddenly remembered what came next after a BDSM seance.


Too exhausted, all Shiena managed to say weakly was her safeword to stop, before panting. She was worried that Otoya might not listen to her, but apparently, she did, since she stopped.

Shiena never had such an intense orgasm in her life. But, she wouldn't say that she really liked what happened. She was not really into BDSM, and she was scared during all the time, afraid that Otoya might hurt her or worst, kill her. But despite the fear, she couldn't deny that it was physically pleasant. The mix of so many emotions such as fear, lust, pride, despair, embarassement, as well as sensations like pleasure and pain, had been a quite pleasant mix for her body, it made everything even more intense, it made her more sensitive. So, even if she was neither a masochist or a sub, she still somehow appreciate this BDSM seance, but mostly just for the result.

Suddenly, she heard Otoya left the room. Shiena remained tied up and blindfolded on her bed, too exhausted to wonder where her girlfriend went. After what appeared to be a minute or two, Otoya came back. Then, Shiena felt that her hands were unhandcuffed, much to her relief. She was seriously began to feel pain in her shoulders due to the fact her hands were tied up in her back for so long, in an uncomfortable posture. Then, Shiena felt Otoya's hands gently stroking her shoulders, which surprised Shiena. But, she must admit that after what she went through, it felt good.

"Otoya..is she giving me a massage?" Shiena wondered, before she remembered something. She was relieved to see that Otoya didn't forget about aftercare.

Otoya then proceeded to massage her upper back, which made Shiena purred. After a moment, Shiena felt a cold liquid on her butt, before her girlfriend suddenly stroke her ass. Shiena was still sensitive there due to the rough spanking, almost like it was on fire. She guessed that Otoya must have put a moisturizing cream to relieve the pain. Then, she flipped Shiena on her back and the latter felt some wet and cold cloth on her sex. It was probably meant to ease any potential sore there, since Otoya had been pretty rough there.

Shiena then felt the same liquid being spread on her breasts, probably since Otoya had pinched her nipples. Shiena was really surprised that her girlfriend was acting so nicely, it wasn't like her. Though, with Shiena, Otoya could be sickly soft if she wanted, but Shiena knew that it must be because her girlfriend didn't want to damage her "property".

Since Shiena's hands were free, she was tempted to remove her blindfold, but she didn't dare to, in case it bothered Otoya. Her girlfriend then stroke Shiena's cheek, then her jaw. After she had kept a red ball in her mouth while she was screaming, Shiena must admit that it felt kind of good to have some kind of jaw massage. After a moment, the blindfolded was finally removed.

The first thing she saw was Otoya's sweet smile. Apparently, her girlfriend was enjoying herself, she liked to take care of Shiena somehow. Even if it seemed to be a kind gesture, Shiena knew that there must be a twisted reason why Otoya liked doing that.

Otoya then laid down next to her and covered both of them with a blanket. She then happily snuggled against Shiena with a childish expression. Otoya really looked innocent right now, when in reality she was the complete opposite. But despite knowing that, Shiena's heart was fooled and couldn't help but feeling happy somehow. She even snuggled back, almost forgetting who Otoya truly was.

"So I suppose you liked it," Shiena said.

"Yeah, I loved it! Thanks for initiating me to BDSM, it was such a good idea. I hope I wasn't too rough on you. But since it's your kink, you should be fine, right?"

"Oh, uh, yes, of course! I like BDSM, so I was fine. It's just that I was too exhausted at the end."

Well, it wasn't entirely a lie, without being totally true either. But Shiena was honestly relieved to see that Otoya enjoyed doing this. Maybe she'll really be able to cure her of her murderous desire. Even if Shiena wasn't really into BDSM, she was ready to continue pretending she does and perhaps eventually, she'll truly like it. Anyway, it wasn't like she disliked it either, and she considered that it was the price to pay for dating a psychopath serial killer and making her stop killing innocent people.

"Hey, Shiena-chan. I made a lot of researches about BDSM, especially the different dom/sub relationship, and from what we did today, I think I have found what type of BDSM I'm interested in."

"Oh, really? So...what it is?"

Shiena felt a little bit worried, but she was also curious. What kind of dom Otoya wanted to be? Shiena hoped it wasn't the sadist type, since she didn't like pain. A dominatrix perhaps? But Otoya didn't strike her as the type who wanted to be call mistress, wear a leather suit, or would insult her sub. Otoya was far from being vulgar or rude, but she was a real tease and bully. Or perhaps just the classic dominant…

"Pet play ~" Otoya replied cheerfully, as she took Shiena into her arms to hug her fondly. "Ah, I can't wait to test the leash on you ^^"

Shiena remained speechless. Even if she was surprised at first, Shiena quickly realized that it made sense, given how Otoya acted with her. Really, she knew that she should have expected that.


So, did you like it? Because I enjoyed writing it xD (as well as thinking about OtoShie BDSM scenarios)

Yeah, I'm pretty sure that if Otoya does BDSM, she would most likely be in pet play.
