Unable to speak, she simply stared up at him as he tugged a little harder.

"I won't do that though. I'm sure I'm not the only one who would miss this organ. Aizen-sama made it clear that I was to cause no permanent harm to you," he regretfully released her. He looked down at her. She looked even worse than before. On top of how worn she appeared before, her shirt was open and her pants were around her knees. She appeared slightly uncomfortable with being only half dressed…or half naked. One or the other would have been preferable. In spite of her discomfort, she said nothing and waited with unnerving patience for him to proceed. Her breathing started to calm as she sat before him and her eyes were still foggy but they seemed slightly clearer than when he'd first brought her into the training facility.

At that point, it turned into a sort of waiting game. She was waiting, as she knew he wanted her to, for him to proceed. He was trying to hold out to see if she would act first out of impatience. If she had been in better spirits to begin with, she may have been impatient. However, she was rather drained and willing to wait for her next instruction.

After several long minutes, he gave her a very small but pleased smile. "It appears you are learning," he teased.

She could feel the power of the collar on her beginning to wane. "It appears you're enjoying yourself," she teased back only to receive a sharp slap across her cheek.

"Enjoyment is not relevant," he told her as he stood. When he did, he made sure to place a firm foot on the end of the leach as it lay on the ground in front of her, effectively pinning her on her knees.

She gave him as dirty a look as she could manage in spite of how amused she was by him. In response to the look, he grabbed her by the hair and pulled her head back, causing increasing strain on her neck. She made an involuntary sound of discomfort as he forced her to look up at him. He looked into her eyes again and confirmed that they were, in fact, much sharper. That and the slow, steady leveling out of her energy told him that his time was running out. He needed to use what little time he had left to his advantage.

"I don't care how relevant it is…you are enjoying yourself," she managed. "It's okay, you can admit it," she attempted to coax.

He gritted his teeth and pulled even harder. She made another sound of discomfort and considered taunting him again but before she could, he threw her to the ground where she landed with a soft thump. She didn't bother to catch herself, because she knew he'd prefer that, but she couldn't stifle the slight giggle that bubbled up from her slumped form. Her giggle caused him to kick her in the side. He knew she was provoking him, but he didn't care. She needed to learn not to provoke those in charge of her anyway. She gave a heated growl as the pain sent searing shocks through her body.

That sound sent a shiver down his spine and he wasn't sure what to make of that. It wasn't necessarily a dangerous sound, though it sure sounded that way. It was something that made his body warm. He watched in fascination as her body slowly rose and fell with each breath. When he saw a trickle of red blood start to run from the corner of her parted lips, he used his foot to roll her onto her back. The sight of her there, prone on the ground at his feet, was more than he could take and decided then that their lesson for the day was over and it was time to move on to other things.

Taking the end of the leach in one hand, he knelt down on top over her, straddling her hips. He watched her face as he flicked his tongue out to lick the blood away from her lips. She closed her eyes tightly and attempted to suppress a shudder. She wanted to reach her hands up to touch him and to lean into his touches but she somehow kept herself from doing so. Once the blood was gone, he moved, once again, to the hole in her throat. With a grin, he watched her hands tremble and heard her whimper as he ran his tongue along the inner edge. Pleased by her minute but intense reactions, he allowed his sharp teeth to graze the edge. Her back arched and her head tilted back, allowing him better access. He took his free hand and grasped the back of her neck as she lifted off the ground and put two fingers inside the hole to hold her in place. At the feeling, she gave a sharp gasp and her eyes flew open. His nails dug in to keep her from jerking away, causing her to gasp again.

He smirked and pulled away to look into her eyes which were staring back at him, wide and sparkling. Her energy was beginning to stabilize but she wasn't trying to use it. This was the sort of submission that he'd been waiting for. "You've done very well today," he told her as he withdrew, leaving her lying on the cold ground beneath him and between his knees.

Though the look she gave him was heated, he was also quite patient.

"Are you willing to allow me to do as I please with you?" he asked as he traced his fingers over her exposed stomach, watching her muscles twitch beneath her sweat-slicked skin.

"Haven't I already proven that?" she tried not to sound too smart, but she couldn't help it as she felt her power returning.

She had and he was finally willing to reward her for that. Suddenly, he'd flipped her over onto her hands and knees and he was kneeling behind her. Finally, he removed her pants the rest of the way. She made a small mewl of satisfaction when he spread her heat wide open.

"Your body is lewd," he criticized.

"I know," she agreed with a heated sigh.

That wasn't the sort of answer he was expecting but he liked it nonetheless. "I didn't get a good look at you last time," he told her as he pushed her head down to the ground and making her ass stick up further in the air, exposing her to him further.

She willingly accepted his advances. "That's because I didn't let you. I wanted to be able to look in your eyes when you came for me," she told him.

"Is that so?" he sounded slightly impressed.

During this exchange, she was trying her best not to squirm too much or, more likely, push back into the investigative touches that he was allowing her to receive but when he pressed a finger against her swollen clit, she couldn't stifle her outburst.

"Well, your body may be lewd but at least it's honest." He pressed against the nerve again and was rewarded with an even throatier cry. "And if I remember correctly," he paused to flick his tongue out at her dripping wetness, "Mmmm….it is also quite delicious."

"Is that so? Aizen-sama told me that I am a little too bitter for his taste," she remarked, trying to distract herself and keep her composure for as long as she could.

Ulquiorra wasn't sure what to think about that. "That is because he is not one of our kind." He told her before lapping at her slit.

That ended their conversation.
She pressed herself against his teasing mouth and, to her surprise, he stuck his tongue inside her. She'd expect that after such a bold motion, he would either stop her from moving or stop what he was doing entirely. So, it was a pleasant surprise when he began to accommodate her further.

Her taste and scent were almost too much for him to handle and once he really got going on her, it was difficult to pull away but this time it wasn't because she wouldn't let him. He could hardly bring himself to stop when he felt she was about to come for the first time.

She whimpered and tried to push against him again when he pulled away. This time she received a sharp spank, "Don't come before I give you permission to," he ordered her.

"Or what?" she demanded.

"Or nothing. Just don't."

She recognized this as a test of her self control and nodded in agreement. She knew there would be some sort of consequence if she failed but that wasn't something she wanted to think about.

Satisfied with her response, he went back to what he was doing. As he did, she looked down between her legs at what little of him she could actually see, mostly his legs. There was a noticeable change in even this small portion of his appearance that made her smile but didn't help with her self control. He was finally getting hard. She groaned at the sight.

When her gasps began to turn to sighs and moans, she spoke to him again, "Do you mind if I cry out…it just…" she tried through his administrations.

He paused for a second which seemed like an entirety to her before replying, "I'd rather you didn't…but if you must, I will let it go this time." In actuality, he, of course, loved the sound of her crying out for him as he touched her but this would be much more fun and he had the feeling she would make just as much noise either way.

"Nnngh…thank yo-ah…" She went back to focusing on controlling the pressure building inside her and trying not to cry out too much.

He smirked. This was control and he loved it. On top of that, Aizen-sama would be very pleased.

He was being much more gentle than before, taking his time to taste her and search out especially vulnerable spots with his long, rough tongue. When he found one, he made sure to exploit it. When he finally pulled away again, she was trembling and her breath was ragged. Her head was turned to one side, so he could see the strained expression that decorated her features.

"Mmmm…." he made a small, near growl as he ran his hands around her hips and up her back, stopping momentarily at the large number centered between her shoulder blades. When he touched it, it made him shiver. His lips twitched into a slight grin. He was having his way with the most powerful of their kind and he loved every second of it. He leaned down and whispered into her ear, "Do you want me to fuck you?" he asked her in a conversational tone that he knew would drive her crazy.

She looked over her shoulder at him. Her lips were parted and her eyes were glazed with lust but the fog that was present when they began had totally dissipated. "Nnngh…yes….but as soon as you enter me…I'll come," she warned in a raspy voice and watched him for a reaction.

He smirked as he starting removing his shirt. "Perhaps I shouldn't then."

She made a small, involuntary whimper at the thought but didn't outright protest. Her tension was eased when she heard him remove his pants.

"But since you've been so good we might be able to come up with something." Using the leash, he pulled her up to her knees and wrapped his free arm around her waist to steady her. "Give me total control of your body," he commanded.

"You have total control," she told him. "I've had my strength back for some time now but I've chosen to remain restrained."

"You know that's not what I mean. I want to control you like you did me," he elaborated, allowing his lips to ghost over the outer rim of he ear as he spoke, a sharp contrast from the way he was holding her.

She shivered. "But then if I come…you will too. I can barely hold back as it is. Wouldn't that cut your fun a little short?"

He chuckled, "You under estimate my will." Under normal circumstances, she would have been right but Aizen had given him a rather odd present when he returned from his mission. A cock ring. At first he didn't know what it was and when Ichimaru explained it to him, he wasn't sure if he quite understood the point of such a ridiculous object. However, once he gave it some consideration, he realized just how valuable something like that could be…in the right situation. He pushed his hard length between her thighs. She let out a deep moan and threw her head back, exposing her throat to him. Her skin around and under the collar was reddened. He ran his tongue along the fevered skin as he let go of the leach and used that hand to toy with the hole in her throat once again. As he slid between her legs, he could feel her dripping wetness coating his anxious member.

When she didn't respond, he dug his nails into the sensitive inner flesh of her soul chain hole. She let out a sharp cry. "Well?" he growled into the side of her neck.

This was the moment of truth. She had a clear choice to make. Either grant his request or she knew she would not be satisfied. He probably wouldn't either but that fact seemed to bother him less. It would be her ultimate submission to him. It would, of course, be temporary but that didn't matter. The fact that it could and might happen was almost enough in itself.

"Okay…if you think you can handle it…" she taunted. She would give in to his demand but there was something she wanted to do first.

He kept his grip on her tight when he felt her energy begin a controlled surge. At that point, he couldn't tell if she was getting ready to do as he said or if she was powering up to break free. At first it was neither. After a few seconds, the collar near his lips grew hot and shattered. That's when he really felt her energy surge, it was greater than any he'd felt from one of their kind, nearly on par with their masters'. It was a crushing force and he found it difficult to breath as he felt it gather around him.

Slowly, she rolled her head to one side and whispered in his ear, "Breath…or you'll die when I do this," she told him.

He hadn't realized that he'd stopped breathing but as he started again, he found his senses begin their return. Once she could feel his soft breath on her neck again, she concentrated her energy and gave all of it to him. She felt him throb between her legs but he didn't come. He smirked inwardly at his victory as he held her near-limp body in his arms and only noticed how tightly he was holding her when she began to gasp and choke for air. Slowly, he loosened his grip and looked down at her body, licking his lips. As his eyes made their way up to his throat, where his nails had dug into her soul chain hole, he noticed a small trickle of blood.

Upon that sight, he moved his fingers from the hole to her lips. Weakly, she opened her mouth and began licking the blood away. Before she could finish, he pulled away again to lace his fingers in her hair, forcing her to turn and lean back even further. With his new access to the blood trail, he began to carefully lap it up, working his way toward the hole. As he did, she purred, a sound that resonated through both of their bodies.

He slid in and out of her thighs as he cleaned her wound and began messaging her breasts with the hand that had been around her waist. Once the numbness of the energy transfer began to fade away, she began to moan.

When the wound was clean, he pulled way, licking his lips. He, once again, took a short moment to admire her and his effect on her. Just the sight of her was enough to make him appreciate the ring physically obstructing his orgasm. When the sensitive spot on juncture of her shoulder and neck caught his eye, he immediately leaned back down and sunk his teeth into her flesh. She let out a sharp, but heated, cry and he could feel her twitching and dripping over his cock.

He pulled away, fresh blood staining his perfect lips, and looked her in the eye, "I didn't say you could come," he scolded.

She was a little upset that he apparently didn't plan to let her enjoy her post orgasmic daze. "I didn't mean to…" she weakly defended, "But you just…" she couldn't continue. She didn't need to.

He didn't reply. Instead, he moved back to the wound and bit into it again, even harder. Once her blood really began to flow, he withdrew to lap it all away, not wasting a drop. When he was satisfied with the wound, he pushed her back down onto her hands and knees.

Using only her thick juices that coated his cock as lubrication, he thrust into her ass. He didn't stop or slow for her to adjust, simply riding her until she began to moan again. Occasionally, he would reach a hand down to her pussy to get more lubrication for his rough administrations but wouldn't linger there for very long.

Through this, she gritted her teeth and groaned both in pleasure and in pain. Had he been paying more attention to other parts of her body as well, it would have been more pleasurable. Eventually, he did, reaching one hand between her legs to toy with her clit while the other easily held her in place. He pinched the nerve repeatedly until she began to cry out again. "Ahhh-nnngh…ah-it's happening again," she began to tremble.

The thought made his cock twitch and he decided to finally allow her to release. "Go ahead, come for me," he encouraged.

He barely finished his words when he felt her body clamp down on his and another rush of fluid on his hand. As her orgasm subsided, he withdrew and began teasing her pussy with his length once again.

"Do you still want me to fuck you?" he asked knowingly.

She looked over her shoulder at him and nodded, "Yes."

Without hesitation, he plunged his swollen and engorged member inside her and she was right, as soon as he did, she came again. Not that that stopped him. No, it was all the encouragement he needed to slam into her even harder with each subsequent thrust. Her sounds of pleasure filled the training facility once again.

She came three more times like that before he released the ring's clasp and she came a final time as he poured himself insider. As he did, they could feel her energy leaving him and returning to her. They collapsed in a heap on the floor, short of breath and barely conscious.

His mind was reeling as he stared up at the cold stone ceiling. Did that really just happen? She rolled over onto her side to look at him and giggled at his expression. It was the same emotionless one he usually wore but she found it amusing that he would wear it even now.

"I'm tired. Are we done for the day?"

"Apparently, we still need to work on your complaining…but that can wait for our next lesson," he half joked.

She gave a sigh of relief. "Thanks." She stood and began dressing, all the while giving him pensive looks.

"What is it now?" he asked, still content to lie on the cold stone floor.

"Will you walk me back to my quarters?"

He cocked an eyebrow at her request. "Why?" he asked incredulously.

"I'm…not allowed to walk around by myself. Aizen-sama insists that I need an escort outside of my quarters." She quietly explained.

He gave a sigh of resignation as he slowly stood. Weakly, he redressed and walked with her out of the facility. This time, his movements were slower than hers and he was obviously weakened by their encounter. Controlling her energy had put a visible strain on him and he lost consciousness before they were half way to her quarters.

She gave his fallen form a soft smile before tossing him over her shoulder and carrying him the rest of the way.

Once again, she was stopped by Gin. "My, my…what do we have here?"

She bowed carefully, so she wouldn't drop her escort. "Ichimaru-sama, Ulquiorra-san was escorting me back to my quarters after training when he collapsed. I didn't know what else to do so I decided to carry him the rest of the way. I hope that is alright," she prayed.

He gave her an unnerving smile. "It seems he is doing his job quite well so I think this is passable. I see he removed your collar?" he assumed, taking a few slow steps toward her.

She fought the urge to back away from him. "It shattered during our training," she carefully told him. "I broke it…but only because he wanted me to."

"I see. That's very interesting." He thought for a moment. "Give me his eyes," he told her.

She started a little at his request. "His eyes?"

"Don't worry, they will regenerate. Aizen-sama will want them and I was on my way to see him. I will deliver them for you."

She set down his unconscious form and pried open his eyelids, revealing his lifeless green orbs. With her fingers only centimeters from his eye, she hesitated again.

"Go on dear. He does this all the time. Let's not keep Aizen-sama waiting," he encouraged as he leaned over the pair to observe.

She sighed and pulled out one of his eyes, then the other. She watched his lids slide shut as she handed Gin his prize. He gave her an appreciative smile as he slid them into the pocket of his shirt sleeve. "Thank you. Now, be on your way." He continued past the pair and toward Aizen's room.

Once he was gone, she gathered him up once again and finished the walk to her quarters. She laid him on her bed while beginning to draw a bath for them. She was surprised that he hardly stirred when she undressed him and slid him into the bath. Only once he was submerged up to his chin did he show the signs of waking.

"Nnngh," he groaned and brought a hand up to cradle his head. As he gathered his senses, he became concerned. "Why am I wet…and naked…and what happened to my eyes?" he demanded.

She tried to hush him, to ease him but it only seemed to make him more anxious. "Calm down," she told him softly before telling him about what happened after they left the training facility. "I'm sorry. I didn't really want to give him your eyes," she had more to say but he cut her off.

"No, you did very well. I was about to take them to Aizen-sama myself after I brought you back to your quarters." Once she explained the situation, he was much more at ease.

"Why does he need your eyes?" she suddenly asked.

"So he can see what happened," he told her as though she should have already known.

She gave him a startled look that went unappreciated by the man sharing her bathtub. "Why?" was all she could manage.

"What do you mean why? So he can see what sort of progress you are making."

She grew silent for a few moments.

He could sense her apprehension. "Don't worry. I think he will be quite pleased," he told her with the slightest grin.

With that out of the way, she began to bathe them.

"That's really not necessary," he told her, weakly trying to push her away.

"Please, just let me do this. You've been greatly weakened. Rest and regain your strength, let me do this for you," she urged.

Without further fuss, he relaxed and enjoyed her touches in his darkness.
