Sensual Experimentation

Lord Aizen sat listening to his eighth Espada drone on about an experiment he was about to start. Aizen gave the pink-haired man the most bored expression. He cupped his chin in his hand and leaned on the arm rest of his throne, cocoa eyes showing slight irritation. Szayel continued talking as if he did not notice; most likely he didn't see his creator's lack of interest.

"What is the point of all of this Szayel?" Lord Aizen questioned. "We have no reason to research humans."

"I've just got an unquenchable curiosity about them," Szayel said flipping his coral hair out of his face. "I've already explored every aspect of their anatomy from the inside out. There is one, I suppose I should say, performance that has piqued my interest in how they respond."

"And what act would that be Szayel?" Aizen asked, still not showing any further interest.

"Mating," he said with a miniscule smirk. "I want to study the reactions of humans when mating with another being not of their species."

Aizen sat up slightly at this, now there was something intriguing. So Szayel wanted to study human sex did he and with other beings. He supposed he meant Arancar and maybe Shinigami. Aizen felt himself grow more interested. They just happened to have a human girl at Hueco Mundo; a beautiful, shy, shapely girl. Her grey eyes always held a sense of purity and innocence; how the powerful man longed to snuff it out of her. Of course he had to wait for the right moment like this. They had no reason to do such things, but it would be entertaining to say the least.

Lord Aizen stood and Szayel bowed to him. "I will allow this experiment to proceed and check in to see your results."

"One more request Lord Aizen," Szayel said smoothly. "I will need one Espada and one Shinigami to decipher if there are differences in her responses to sexual activities with partners of different backgrounds."

Aizen thought for a moment. Which Espada should he choose to have intercourse with their little princess? Yammy, Aaroniero, and Baraggan were a definite no. The large Espada Yammy would probably rip her in half by accident, Aaroniero looked like the type to have strange fetishes that would scar her, and Baraggan was just too old. Starrk sounded like a good candidate, but the Primero Espada was too lazy for it. Harribel was not into women. At least that is what he believed, but that didn't matter because he was not pleased by acts such as that. Nnoitra or Grimmjow would kill her with their power and twisted ways of intimacy. Szayel was watching the experiment and Zommari just didn't fit. He would most likely be uninteresting.

"Lord Aizen."

"Ah Ulquiorra," Lord Aizen said smiling while looking over at his Quarto Espada who had just entered the vast throne room. "What is it?"

"I have just fed the girl," he said, his voice relieved of emotion, emerald eyes showing nothing. "She is coming around a little after three months of being here."

"That is good," Lord Aizen said taking a step toward Ulquiorra and running his hand over his own brown locks. "Speaking of the girl, you will assist Szayel in an experiment concerning her."

The dark-haired Espada turned to Szayel. "What is this experiment?"

"Oh it's nothing too hard really," Szayel responded, grinning and adjusting his glasses, amber eyes slanting when a smirk crossed his features. "You just have to perform intercourse with her while I record data on her responses."

Ulquiorra's eyes widened. "You expect me to do what?"

The Fourth Espada couldn't believe what he was hearing. He was expected to...mate with that human trash? Why would Lord Aizen choose him over the others? When he thought about it for a moment, there were numerous reasons why. He was the only one who saw her on a daily basis so she had some sort of an attachment to him and the others just weren't suitable for such a task. Still this was not something Ulquiorra was looking forward to. It was beneath him and degrading that he would have to do such a weak thing as consummation.

"We will start the experiment tomorrow," Lord Aizen spoke. "Gin."

The ex shinigami moved fluidly into the room wearing his strange smile. His lilac colored hair framed his face and although his eyes were closed, he still moved gracefully to his cohort's side. "Yes Aizen?"

He looked at Gin with satisfaction. He and Tousen were the only ones permitted to call him by his name alone even though it wasn't often. They were his loyal accomplices and their trust in him had never wavered. They had been with him from the very beginning from the first experiments Aizen did on the soul reapers to when he deflected, taking the Houygoku from Rukia Kuchiki and leaving the Soul Society. He was quite fond of both of them and realized what great assets they were to furthering his plans. He grasped one of Gin's arms and brought him closer and waved a hand toward Szayel.

"You may now have your wish with Orihime because of research Szayel is conducting about mating between species."

Gin's smile seemed be wider than it usually was while he laced his thin fingers together. "Oh my, I can't wait."

Aizen chuckled before dismissing everyone, waiting to see just what would become of this experiment.

-------------------------------------------------------------------------------------------

Orihime's eyes widened in shock. "I have to... I have to do it for research?"

"Precisely," Ulquiorra responded, his hands shoved in his pockets while he gazed blankly at her. "You will be taken to Szayel's lab tomorrow where he will first examine your body and then you will proceed to have sexual intercourse for his studies."

Orihime's heart was thumping in her chest. She had to have sex for the sake of research and she had to have that creepy Espada Szayel smiling at her while it happened? Plus it would be recorded? She felt more like she was going to be a porn star than helping further Szayel's research. That wasn't even the worst part.

Tears started to form in her eyes. Ulquiorra saw and turned to face her completely. "What has upset you?"

"Ulquiorra," she whispered, struggling to hold back her tears. "I've never done that before. This will be my first time."

"I do not understand," he responded. "Humans take many sexual partners, yes?"

"That is true for some people," she answered looking at the floor, "but not all are like that. I wanted my first time to be with someone I trust. I wanted it to be special, but now I won't have that opportunity."

"You should not worry yourself over petty things such as that," Ulquiorra scoffed. He turned and left for the door, he looked over his shoulder at her. "You will be having intercourse with me and then Gin Ichimaru."

The color drained from her face. She secretly hoped that the Shinigami she had to have sex with was Lord Aizen or even Tousen. Gin freaked her out to no end with his strangely happy smile and always closed eyes. She had a feeling deep in her gut that it would not be an enjoyable experience with him. On the other hand, Ulquiorra would be the one to take her innocence. When she thought about it, he was the only one he would want to do that here. They weren't exactly best friends, but she was closer to him than to anyone else. If Orihime had a choice, she would choose no one. She hadn't even had her first kiss yet! This was skipping all the steps that lead to sex and it really bothered her.

The shocked female watched her keeper exit the room, tucking her dark orange hair behind her ears sadly.

Orihime went over to her bed and lay down on the small mattress. She wrapped her arms around her body and sat thinking hard until she finally drifted off to sleep.

---------------------------------------------------------------------------------------------

Orihime awoke to the sound of her door being opened. She sat up and jade eyes greeted her at her bedside; she smiled a little. She always did whenever she saw him lately. Orihime guessed she was starting to care for him. She gave up trying to say how wrong it was to care about an Espada a while ago. This was her home now so it didn't matter anymore. She would never see her friends again and she didn't have the strength to argue with herself about what was right and wrong.

"Good morning Ulquiorra," she said standing up, smile faltering when she remembered what was going to happen today. She clasped her hands in front of her.

Ulquiorra continued to look at the woman. "Are you ready?" he questioned.

Orihime sighed. "No, but there is nothing I can do about it."

Ulquiorra first brought her to the bathroom quarters to shower, brush her teeth, and comb her hair. As she grasped a comb and prepared to run it through her orange locks, Ulquiorra took it from her; she turned and looked at him with confusion.

"I will comb your hair."

Orihime smiled at him warmly. "Thank you Ulquiorra."

He looked blankly at her. "Do not misunderstand my intentions. This is not out of affection; you must look presentable for Lord Aizen." He combed her hair with all the gentleness of a lamb while her mood sank even lower. Soon after, they were moving through the twisting white corridors of Los Noches until they came to a certain door. It had the word laboratory written across it in dark lettering. Orihime felt dread building inside of her stomach when Ulquiorra opened the door and motioned for her to come in.

She looked around at all the different specimens he had floating in jars. There were all types of chemicals and machinery buzzing inside. A bed was lying in the on the far right of the room and there were lights and a large camera on a stand in front of the bed. Across from the bed was a desk with two chairs there and paperwork was spread out across the desk. Orihime sighed; she really was going to be a porn star...an unpaid, inexperienced porn star.

"Why hello dear. How are you?"

She turned to the pink-haired Espada's voice and tried to smile, but failed. "I'm okay."

"Wonderful." He turned his back to her. "Follow me Orihime."

She did and Ulquiorra walked alongside her. They reached what looked like the soft tables that Orihime remembered sitting on at the doctor's office. Szayel turned to face her when she stopped walking.

"You will need to remove your clothes," Szayel infromed her, keeping his devious smile. "I need to examine your body and see what condition you are in. Also I will need you to answer a few questions for me."

Orihime's hands shook slightly as Ulquiorra moved behind her to unzip her white jacket. She shrugged it off, exposing her chest. Her cheeks flared pink and she covered her breasts with her arms as best she could. Szayel chuckled at her feeble attempt. He reached out and placed her hands at her sides; her face was turning beet red.

"I cannot examine you properly with your arms covering your assets."

Szayel then proceeded to study her breasts. He grasped them and Orihime's breath intake sharpened. The Espada looked at her before brushing his thumbs over rosy nipples. She jolted forward slightly.

"How does that feel Orihime?" he questioned. "I need honest answers. Do not lie because you are feeling ashamed."

Orihime lowered her head slightly. "It feels...nice."

"So for you, your breasts are one of your erogenous zones."

"What is that?" Orihime asked, cocking her head.

"They are parts of the body that provide sexual arousal when stimulated," he answered, lifting one of her arms and pressing his cold fingertips against the side of her breast. "It varies on the person's preference."

Szayel stood straight and fixed his glasses. "Would you be a dear and remove your pants for me?"

Orihime reluctantly took off her shoes and then stepped out of her white pants. The human girl was so embarrassed. These were the first men to see her body completely naked and she truly did not feel comfortable with it. She looked over at Ulquiorra, his eyes were tracing her body and she almost smiled. It seemed he took an interest in her form and if he liked it, she didn't care what anyone else thought. Still, she was a modest girl and standing there in front of men, especially ones that were not her husband, or anything close to it was highly uncomfortable.

Szayel motioned for her to get on the table and she did. He pulled up stirrups on either side of the table, placing each of Orihime's feet into the looped straps. Her face could not get any darker. Here she was sprawled open for this strange man to examine her most feminine parts, a place where no man had ever been before. She hadn't even been to the gynecologists when she was back in the human realm since she wasn't sexually active. Orihime bit back a sob when he placed gloves on his hands and proceeded to prod her and opened her up for his eyes to drink in. He placed a finger at her opening and she shot up to look at him fearfully. He stood and removed his gloves.

"Your hymen is still intact," the scientist said matter-of-factly. "By studying your vagina, I can tell that you have not had intercourse before correct?"

"Yes," she whispered beyond embarrassed.

Szayel smiled happily and quickly walked over to the bed. "This is perfect. I truly wished to have an untouched woman instead of one that had been sexually active and you just happen to be one. How delightful."

He pointed at the bed and Orihime moved to it and sat down, her heart racing in her chest. The Quarto Espada stood next to her, gazing at her momentarily through emerald eyes. Suddenly the door for the lab opened and Orihime wondered if that was Gin. She truly abhorred that she was going to be forced to sleep with him. To her assumption, Gin soon appeared all smiles as usual. Orihime was surprised though to see Lord Aizen standing next to him. She would die if she had to sleep with three guys instead of two.

"Well well my little toy," Gin said while shrugging off his white robes while Orhime. "I'm going to have some fun with you today. Ulquiorra get started already so I can have my enjoyment; I'm already growing impatient."

Ulquiorra looked over at Lord Aizen who nodded shortly, a soft smile on his face. He and Gin took the chairs that were at the desk and moved them a little closer to the bed. Orihime's eyes widened. They were going to be watching with Szayel when Ulquiorra took her? This day couldn't be any worse. She watched as the Fourth Espada removed his jacket, baring his muscled form to her.

"Alright Ulquiorra," Szayel said after starting the camera, turning on the lights, and grabbing his notes. "You will first have to stimulate her. This will arouse her body and it will start to prepare itself for you. When she is ready, her vagina will be pooled with moisture. I'm sure you can take it from there."

"Yes," Ulquiorra answered.

Orihime's spirits fell. It seemed like he only saw this as an order from Lord Aizen, like he wasn't thinking of what it would be like to have sex with her. Of course he had no emotions so she shouldn't be too upset. On top of that, sex didn't seem like something that he was concerned with like most guys. It made sense because he wasn't human though; it was still a little heart breaking nonetheless.

He crawled on the bed on top of her, forcing her to lie back as he leaned closer. Her breath caught as she looked up into his attractive face. She found herself studying him; Ulquiorra looked so sad and the jade streaks on his face reminded her of tears. She felt like she wanted to comfort him. He supposedly did not have emotions, but the one that always shown through his eyes seemed to be sadness. Orihime knew she was most likely just seeing things, but that's what it seemed like to her.

Gingerly,Orihime reached up and placed a hand against his cheek.

Ulquiorra was confused at her gesture. He could sense that she was trying to reach out to him. The Arancar didn't know how to respond to that especially, since he did not care for the action. He didn't need someone to coddle him, but he still found himself leaning into her warm hand. A small smile crossed Orihime's face and sat up to tenderly placed her lips against Ulquiorra's. The stoice male had never done this before, but his instincts were taking over when he felt Orihime's tongue brush across his lips. He opened his mouth and was interested in the feeling of her tongue exploring his mouth. He convinced himself that this was being done in order to stimulate her and perform his task instructed by Lord Aizen.

Ulquiorra felt her small hands drop from his face to his shoulders.

Unexperienced fingertips rubbed them softly and slid down his firm chest. He was not sure why he felt his body was on fire everywhere her little hands touched, but he didn't want the sensation to fade. He was curious about it more than anything. Why was that happening? It never had before when someone else did this, but then again Ulquiorra never allowed anyone to touch him like this before.

Ulquiorra ran a hand down her side curiously when their mouths parted. He grasped her hair gently and pulled her head back. Turning her face a little more, Orihime submitted herself to him which was exactly what he expected. The powerful Espada was superior to her in every way and he was going to show that. The dark-haired male brought his mouth down to her exposed throat and nipped it softly, his other hand reaching up to grasp her breasts and she moaned softly in return.

Ulquiorra looked at her, enjoying the little sounds she was emitting. He had never heard such sounds before and although he didn't show it, they made his body feel strange just like her hands roaming over his body did. He wanted to hear more of those sounds. If she liked his hand on her breasts, he was sure she would like something a little more explicit. He was not fearful or shy to do anything to her.

Moving down creamy skin, his tongue wrapped around her nipple. She gasped and her hands immediately found his ebony hair, twisting themselves in the silky locks. He sucked gently on her pert nipple while tracing a finger around her other breast. Ulquiorra released it and turned his attention to its twin, kissing the underside and licking along it while he trailed a finger down the valley of her breasts.

Orihime moaned gently, his actions warmed her body further. This experience was new to her. She didn't realize how amazing being caressed by another being could be; it was a feeling that was alluring and arousing at the same time. Most feelings of shyness left her and she wanted him to feel what she was feeling. The human tenderly brought his head back up and kissed his thin lips. She ran one hand along his back while the other caressed his Arancar skull. A grunt escaped Ulquiorra's lips and his hand grasped her hip tightly. Orihime brushed his hair behind his ear and leaned forward to lick the shell of it, realizing that it must be one of those zones that Szayel spoke of earlier.

"Woman," he said sharply.

She did not stop her assault and soon after, Ulquiorra pushed her down and sat on his haunches. He spread her smooth legs slowly and placed to fingers against her, rubbing her womanhood in circular motions. He wasn't sure exactly why he got that reaction, but he had been made to watch a video of what he had to do. Ulquiorra found it utterly disgusting, but now that he was participating in it, the Espada understood why humans mated constantly.

Orihime arched off the bed and Ulquiorra pushed her shoulders back down. His fingers worked wonders against her and she found herself letting out another one of those embarrassing sounds. She clenched the bed sheets in her fists tightly, completely forgetting that she had an audience.

"Do you like this Orihime?" Ulquiorra questioned; he pressed his fingers against her harder.

"Yes," she breathed.

Ulquiorra could feel moisture against his fingertips, but did not feel that she was properly prepared. Turning her into a writhing mess was quite different than his usual methods of defeating an enemy; then again she wasn't his enemy. Who exactly was she to him? She had to be nothing. That's what he always saw her as, but now he couldn't explain his strange interest in performing these "acts" with her. Things weren't making much sense.

Ulquiorra got on all fours, brushing a hand over her porcelain thighs, intrigued how soft they were. He kissed one and then moved his head between her thighs.

Orihime arched off the bed once more, her eyes widening. Hands locked tightly in his hair and she panted hard. Ulquiorra swirled his tongue along her inner folds then used it to enter her; she moaned loudly at the intrusion. Ulquiorra took his thumb and rubbed her little bundle of nerves softly while his tongue was squeezed by her internal walls. She had such a unique flavor that he had never tasted before. He wasn't concerned with that, only in making her more submissive to him.

As his other hand wrapped around her thigh, he pulled her legs open farther. Ulquiorra felt satisfaction from how he was able to please this woman. He had never lain with someone before and he had to say he found in quite entertaining. His member was so hard it nearly hurt and it never had done that before, he wanted to be inside her to release the uncomfortable feeling.

Gin watched on, stroking himself through his pants. He never thought Ulquiorra could be so...sexual. It was quite intoxicating watching the silent cold Espada pleasing a woman. Gin found that their moans made him more turned on. Moans were his weakness; they made his body act in ways it normally wouldn't.

The smiling shinigami looked over at Szayel who was diligently taking notes during the performance. With closer inspection, he saw the pink-haired professor had a hard on. He couldn't blame him; the sight was quite erotic. Gin's gaze turned to Lord Aizen. The man's cinnamon eyes were slanted in that seductive way they always were. He was aroused too judging from the tent in his loose pants.

"An interesting sight isn't it Lord Aizen?" Gin questioned, not stopping the motion in his pants. He didn't have any shame around Aizen. They had known each other too long and it didn't bother either of them. They had shared partners even back when they were still in the Seireitei, sometimes even at the same time so there was no modesty although they never touched during their encounters with females.

"It is," Lord Aizen commented, his eyes turning to his follower.

"I'm just a little too in the mood for my own good," Gin whispered while he continued to work his hand over his length, watching Ulquiorra get ready for the main event.

Ulquiorra felt that Orihime was thoroughly prepared when she screamed after her first climax. He reached for his manhood and freed it, placed it at her entrance, and looked at her to let her know he was going to proceed. She nodded tenderly at him.

"You said this was your first time correct?" Ulquiorra questioned.

"Yes," she answered.

"It may hurt."

"I know."

He didn't reply, but slowly inched himself inside of her. Orihime winced at the feeling of being stretched. It wasn't too painful, but it was very uncomfortable. When he reached her barrier he swiftly pushed past it. She yelped in agony and dragged her nails painfully down his back. Ulquiorra did not move for a moment, allowing her to adjust to his size. After a few seconds, he experimentally moved forward slightly; she gasped in ecstasy.

Ulquiorra placed his hands on either side of her and thrust his hips, sliding in and out of her heat. He had to refrain himself from pounding into her like a maniac. He now understood why Aizen chose him over Espada like Grimmjow; that blue-haired maniac would break her in half with his crazy speed and strength.

Looking over, the green-eyed Espada saw that the man with lilac colored hair had his hand down the front of his pants. He was biting his lips and groaning so it wasn't hard to tell what Gin was doing. He took this opportunity to rock into Orihime a little harder. She moaned his name loudly, causing him to jerk into her even harder by accident. Orihime sat up and grasped his hips.

"Can you...do that again?" she asked timidly.

He complied as an answer and slammed into her as hard as he knew she could take it. Her nails ripped into his sides and Ulquiorra listened to her moans during their encounter. It wasn't long before Orihime's walls clenched him tightly and her second orgasm washed over her. Ulquiorra leaned into her shoulder and grunted, releasing inside her. He pulled himself from her and laid down beside the woman. Orihime sat up and threw and arm over his chest, leaning down to kiss his mouth once more.

Gin stood up, his smile remaining while he wiped his hand. "Oh boy, my turn!"
