Hi there. Here's a new BDSM OtoShie smut chapter! I hope you'll enjoy ;)

Shiena began to have a second thought. It wasn't the first time she did that, and last time everything went pretty well. But she couldn't help but still be worried.

Otoya smiled gleefully as she slowly undressed Shiena. She looked like a child hyped to unwrap and discover her birthday present. But Shiena knew she was far from being similar to a kid.

Once she was fully naked, Shiena felt a little bit embarrassed. Otoya had already seen her naked lots of time, but it felt embarrassing to be the only one naked, knowing what was going to happen. Otoya gazed at her, her eyes full of lust, which certainly didn't help Shiena to feel more comfortable.

"Looking good, it's almost perfect. Now Shiena-chan, get on all four would you?" Otoya asked cheerfully.

Shiena obeyed. She had too. After all, this was a BDSM session.

Otoya acted decently these days. This is why Shiena accepted to do another BDSM session. But she wasn't fooled either. She knew Otoya only acted nice to have what she wanted, she wasn't sincere. Otoya never does something without expecting something in return. But it didn't really matter to Shiena, as long as she behaved. She just gave Otoya what she wanted to ensure herself that her girlfriend will continue to behave.

On all four, Shiena was waiting in apprehension for what Otoya had planned for her. She couldn't help but be a little bit afraid. BDSM was about trust and mutual understanding. She didn't trust Otoya at all. But she did have trust in her desire to keep their relationship, she knew Otoya wouldn't do something that could ruin it. Well, she hoped she wouldn't. But at least, they do have some kind of mutual understanding. Shiena made a lot of researches to understand better people like Otoya and what they want, and she was sure Otoya was doing her best to know her better too. To manipulate her, obviously. But as long as Shiena was aware of that, she had the feeling she could deal with it.

Otoya was walking around her, like she was enjoying the sight. She then crouched and put something around Shiena's neck. The brunette realized that it was a collar when Otoya tied a leash to it. She then stood up and looked at her happily.

"Perfect!" Otoya exclaimed enthusiastically. "I knew a collar and a leash would look good on you. You always reminded me of an adorable fluffy animal. So cute."

Shiena couldn't help but blush. So that was what Otoya was into. Well, she did admit last session that she had an interest into pet play. Perhaps it was better this way, it seemed less likely to be too rough or violent. Still, it felt humiliating to be treated as an animal, it was degrading and embarrassing. But as long as she was hurt and it pleased Otoya, Shiena was fine with it. Anyway, avoiding getting hurt and satisfying her girlfriend had always been the purpose of those sessions.

"Now come, let's go for a walk," Otoya said cheerfully as she pulled out a little on the leash.

"Uh? A...walk? W-Where?" Shiena asked, worried.

"Ah, don't worry, we'll stay in the apartment. We can't go outside, someone might see me and call the police. Anyway, I much prefer to keep you all for myself, this sight of you only belongs to me ~"

Otoya then looked at her with a threatening expression, still smiling.

"By the way, pet can't talk. So from now one, you're forbidden from talking. You're still allowed to make noise tho. Understood?"

Shiena was about to say yes, until she realized that she wasn't supposed to talk. So she just nodded, which seemed to please Otoya. She then pulled out on the leash again, leading Shiena out of the bedroom. The brunette walked on her hands and knees, trying to let her pride fade away.

Shiena gasped. Walking on all four was more exhausting than she thought. Her knees hurt a little bit. It wasn't comfortable at all to walk on her knees. She stopped walking, trying to catch up her breath. Otoya pulled out on the leash, but Shiena remained motionless.

"Uh? What's going on, Shiena-chan? Too tired to continue?"

Shiena weakly nodded and Otoya sighed.

"Geez, you really don't have any stamina don't you? Fine, I'll get you something."

Right now they were next to the table. Otoya tied up the leash at the table's leg and went to the kitchen. It wasn't what could realistically refrain Shiena from breaking free, but she knew it wasn't the point. Otoya just wanted to feel like she was in control.

She then came back and put something in front of Shiena. It was a bowl full of water.

"Come on, drink. You must be thirsty," Otoya said.

Shiena wondered if it was a joke. Otoya was smiling but there was something in her eyes that made Shiena believed she was serious. She really wanted her to drink in a bowl like she was an animal.

"Curse those psycho serial killers and their weird sexual kinks!" Shiena thought bitterly.

Otoya's gaze was insistent. Shiena felt like she had no choice. And she was indeed thirsty. Shiena swallowed her pride, leaned a little, and started to lap the water in the bowl. It was refreshing, but she would prefer if Otoya wasn't staring at her with a huge grin on her face.

Shiena didn't like the feeling she got from that. It reminded her of the bullying she went through, of those bullies who enjoyed mocking and humiliating her. But somehow, it wasn't entirely the same with Otoya. There wasn't any contempt in her eyes, she was looking at her with lust and desire. So even if she was humiliating her, her reasons were pretty much different from those bullies. She wasn't motivated by dislikes but by love, or whatever twisted feeling Otoya had for her. And somehow, it comforted Shiena. Even if she didn't like doing that, at least she was doing that for someone who appreciated her rather than despising her.

Shiena managed to finish the bowl. Despite her displeasing position, she appreciated being able to drink some water. Otoya then fondly pat her head.

"Good girl! You deserve a little break. How about we watch some TV?"

Shiena nodded with enthusiasm. Anything except going on a walk again. She followed Otoya to the couch in front of the television. Otoya sat, while Shiena climbed on it. Using the leash, Otoya made her fall on her laps. Shiena's head was now resting on Otoya's thighs. Her girlfriend then turned on the TV.

Otoya put some documentary about wild animals. There were wolves hunting for hares. Somehow, Shiena felt she could relate to those hares. She also felt really bad for them when they got eaten by wolves. That was surely not the type of thing she liked to see.

She looked up. Otoya was smiling, deeply focused on the documentary. She really looked like she was enjoying it. Shiena wasn't very surprised.

She then felt Otoya's hand starting to stroke her hair, and then lowered to her body. Her other hand continued to pat her head. As she continued to watch the documentary, Otoya softly stroke Shiena's back, then brushed her ribcage and belly. Shiena let out a slight moan. She was kind of ticklish there. Otoya giggled a little, her eyes still on the TV. Then suddenly, she cupped one of Shiena's breasts with her hand. Shiena moaned, from both surprise and pleasure. Otoya was gently massaging her breast, then lightly pinched her nipple. But it only lasted for a moment. Otoya's hand then went down, stroking her hip, and then suddenly grabbed one of her ass cheeks. Shiena moaned again, and Otoya moved her hand to inner thigh. She was so close to Shiena's sex, the latter felt like she became wet thanks to all the teasing. But Otoya never went there. She simply stroke her thigh, move up, and pet her pubis.

Otoya continued to tease her like that until the documentary was over, still holding the leash. She touched Shiena at various places, some were erogenous, but she never went for her pussy. Shiena was soaked wet right now.

Shiena then noticed that it was warmer where her head was resting. The warm seemed to be coming from Otoya's crotch. Shiena could also smell a strong scent coming from there. Was Otoya wet too?

"Uh, Shiena-chan, what's that?"

She showed her her fingers. They were wet. Shiena realized that she must have been so wet that it dropped on her thighs, which allowed Otoya to discover it. Shiena felt so embarrassed right now, she was blushing in shame.

"Ah, such a mess. You're so dirty now," Otoya reprimanded, barely hiding how happy she was. She then rose up and pulled on the leash, forcing Shiena to get off the couch. "Looks like I have to give you a good bath."

"Good. You're all clean now, you can get out," Otoya said cheerfully.

Shiena was sitting in the bath, in the warm water. She wasn't sure how she felt right now. Otoya had washed and cleaned her like an owner would do with their puppy. Her girlfriend never got in the bath, she simply washed Shiena with care. It made her feel like she was some kind of dirty dog. But, she didn't dislike it. Being washed with so much care did feel good, even if it was kind of weird. Otoya did seem like she enjoyed every second of it.

Shiena got off the bath and Otoya welcomed her with a towel. Her girlfriend gently wiped her dry. Shiena felt a little bit awkward, but she didn't dislike it. Otoya then used a hair dryer to dry Shiena's hair. She then gently brushed her hair and even did her braided pigtails. Shiena kind of like all the little cares Otoya gave her.

"Perfect! Those really suits you well, Shiena-chan. You're cute."

Shiena couldn't help but blush. She couldn't resist Otoya's words, they always managed to get to her heart.

"Now let's go back to the bedroom so we could play together," Otoya said happily.

But before Shiena could go on all four, Otoya suddenly stopped her.

"There's no need for that. You must be tired to walk like that. Let me carry you."

Otoya gently lifted Shiena in her arms and carried her to the bedroom. Shiena didn't know Otoya could be that chivalrous, it made her heart raced a little.

"Play? What is she gonna do? Ask me to go seek the ball or something?" Shiena though. "All she did was treating me like a dog. Is that all she wants to do with me?"

Otoya then put her down on her feet, took something in the drawer, and go sat on the bed, tapping on her laps in an inviting way.

"Come here Shiena-chan, and sat on my laps," Otoya asked with a charming smile.

Shiena blushed again and obeyed. She walked towards her and then sat on her laps. Otoya then opened her legs a little, which made Shiena's spread hers. Otoya then showed her what she had taken from the drawer: a pair of handcuffs with pink fur.

"Shiena-chan, put your hands behind your back," Otoya ordered with a sweet smile.

Shiena obeyed and Otoya handcuffed her hands behind her back. She then gently pat her head.

"Good girl. You had been very obedient today, so you deserve a reward. Would you like that?"

Shiena nodded. She must admit that all that teasing really made her eager to have some actual sexual stimulation.

"If you really want it, you'll have to ask me. But you can't talk human word."

Shiena looked at her, confused. How was she supposed to do that?

"Just meow. I want to hear you meow."

Shiena found it kind of odd. She was wearing a collar and a leash, so why acting like a cat? Though after careful consideration, Shiena preferred it that way. It sounded less embarrassing to meow than bark.

"M-Meow…"

"Again."

"Meow."

"Again!"

"MEOW!"

Otoya giggled. She looked gleeful.

"Shiena-chan is so adorable right now."

Shiena blushed, both from embarrassment and happiness.

"Very well, I shall reward you now."

Otoya gently fondled one of Shiena's breasts, before she started to lick her nipple. With her other hand she cupped the other breast and teased the tip with her thumb.

"..Aahh…" Shiena moaned softly.

Shiena lost her balance and felt like she was falling. But Otoya caught her thanks to the leash and brought her back towards her. Shiena's fell on Otoya who was now holding her. She heard her girlfriend giggled softly.

"You're so sensitive, how cute."

Otoya continued to play and teased her breasts. Shiena then felt her warm breath on her neck, followed by a kick lick. Otoya then nibbled her ear.

"Mmmhh…" Shiena let out.

It felt good. Shiena could feel that she was beginning to be wet again. But she couldn't bear all this teasing anymore, it was almost a torture. She wanted to be touched down there so much, but she couldn't ask for it. She wasn't allowed to talk.

She then felt Otoya's hand stroking her belly, going down. She then stroke her thighs, and brushed her fingertip on her inner thigh, near her crotch. Perhaps Shiena's wish was about to become true. Shiena really hoped so.

"My, my, I can already feel your love juice and I'm not even at the source. Looks like your bath was a waste, you're about to get dirty again," Otoya teased.

Then it finally happened. Otoya's hand reached Shiena's sex. She then started to rub her slit really slowly. But given Shiena's state, it was enough to make her moan from pleasure.

"Well, looks like you were really eager for that. Do you like my fingers that much? Do you want me to go faster?"

Shiena nodded. Otoya smiled with satisfaction.

"Of course you do. Since you have been such a good girl today and you're so honest, I won't make you wait even more. You better be ready!"

Shiena was ready. Her body was ready. This was what she wanted since the moment Otoya started to tease her during the documentary.

Turned out she wasn't as ready as she thought.

She felt a violent jolt of pleasure browsing in all her body when Otoya went faster. Her girlfriend was so rough. She moved her fingers in a circular motion to stimulate her clit, before penetrating her with two fingers. She was thrusting her fingers back and forth at a great pace, before she went back to rub her clit, alternating between those two actions. Shiena let out multiple loud moans of pleasure, which seemed to please Otoya greatly.

"So naughty. Do my fingers feel that good? Then come by them, Shiena-chan!"

Otoya suddenly went even faster. That quick pace was too much for Shiena. She was going to come. But suddenly, Otoya stopped for a moment.

"Maybe not," Otoya teased. "Ah, just kidding!"

Shiena didn't have the time to complain in any way that Otoya suddenly fingered her again, at the same quick pace. This small break had made Shiena's body even more sensitive. The amount of pleasure she was feeling right now was almost painful.

"Come for me!" Otoya ordered with an wild joy as she used the leash to bring Shiena closer to her.

This is exactly what Shiena did. She came with a loud moan of ecstasy. The climax was so strong, it lasted so long. Then Shiena felt her body becoming numb. She was extremely dizzy and felt blissful.

She may not be really into BDSM, but she had to admit that, given the orgasms she had, it worthed it. She panted to catch up her breath, resting in Otoya's arms. She then noticed that her girlfriend was sniffing her hair.

"Ummm, so good...this feels so good. I can't wait anymore, I'm at my limit," Otoya mumbled.

Otoya suddenly raised up, still holding Shiena. She then gently put the brunette down on her feet, and dropped her pants.

Shiena could see some wet substance saying attached to her panty as she removed them. Otoya was soaking wet. She glared at Shiena is a smile full of perversion, her cheeks blushing and her eyes shining with lust.

She then sat back on the bed and opened her legs, giving a full view of her pussy. The lips were swollen and her clit fully expose. She was clearly in great arousal. Shiena wondered how she managed to keep her composure so long in that state. Was she like that since the documentary? It would explain why Shiena was able to smell it earlier.

Otoya waved at her and gave her a kinky smile.

"Shiena-chan, come here. I can't wait any longer, come pleasure me with your month ~"

Shiena didn't make her wait. She got in front of her and knelt between her legs. But as soon as she was there, Otoya put her hand behind her head and pushed her to her sex eagerly. So Shiena didn't lose any more time and started to lick her pussy. Otoya immediately reached by letting out a soft moan.

Shiena licked her pussy up and down with great care, tasting her love juice. She then gave quick licks on her clit, and went back to lick all her slit. She felt Otoya's hand grabbing her hair, without pulling it.

"No teasing with me, just get to the point," Otoya ordered with a threatening voice.

Usually she was fine taking her time, but now she was so eager. It seemed that Otoya was really holding back for too long. Shiena obeyed and started focusing only on her clit. She licked it with care and then sucked on it.

"Mmmh yes, continue like that...ahh…" Otoya moaned.

Shiena started to lick her quicker, still putting all her effort on her clit. Otoya had her two hands on each side of Shiena's head, preventing her for recoiling. Shiena rolled her tongue around her clit and then sucked on it again.

"Y-Yes, that's it, you're doing good...mhh...ahh...I'm gonna come!"

Shiena felt a slight squirt on her face as Otoya let out a strong moan that almost sounded animalistic. Shiena felt her nails digging in her scalp, before she released her head. Otoya fell on the bed, breathing heavily. Shiena understood that she had come and stood up. Her girlfriend had a blissful look on her face and was heavily blushing. Shiena found her cute right now, even though she knew she was a psycho serial killer.

Shiena wondered what she should do. Was it over? Otoya didn't seem like she was about to continue. Shiena went to the bed and climbed on it. She then laid next to her girlfriend. Otoya suddenly climbed fully on the bed too and hugged Shiena, rubbing her cheek against hers like a happy child.

"Shiena-chan, thank you. I liked it. I love you ~"

Shiena felt her heart racing.

"I...I love you too!" Shiena replied, blushing.

She then felt that her hands had been freed. Otoya had removed the handcuffed. She then removed the collar and leash.

"Do you need anything? Are you okay?" Otoya asked.

"I'm fine, thanks. Now I just want to rest...in your arms."

Shiena felt embarrassed by her request. She felt weak. But she wanted some comfort, even if it was from Otoya. And somehow, she feels good when she was close to her. She knew it was fucked up to feel that way towards a serial killer, but she couldn't help it. She was in love.

Otoya smiled happily.

"Of course."

They both went under the blanket and Otoya gently took Shiena in her arms, fondly hugging her. Shiena felt so at ease right now, it was really comfortable.

"Shiena-chan, you were so cute today. Let's do this again another time, okay?"

Shiena didn't have a second thought this time, too happy to be able to please Otoya.

"Sure."

Looks like Shiena got caught in the spider's web. Will she be able to fly away? Meh, probably not. She's doomed xD
