For some reason, I find it oddly appropriate that this turned out to be a thirteen part series. And who knows, maybe the wonderfully evil plot bunny that made me write this will reappear and force me at cero-point to continue. Regardless, I hope you've enjoyed reading this random bit of smut as much as I've enjoyed writing it.


Ulquiorra sighed and tried to take his few moments of peace to center himself. It wasn't often that he was so totally helpless. He tested the strength of his restraints against his own once again, same result, nothing. The straps that securely fastened his wrists and ankles to the table appeared to be made of a soft leather, a rather unusual item to be found in Heuco Mundo. Briefly, he wondered if Szayel had cured the leather himself or if he just went to the human realm and stole them. Not that it mattered either way because they were definitely reinforced with something and the fact that, on first glance, they appeared so disarming was all the more irritating.

The other thing that bothered him was the fact that Grimmjaw had yet to return. Though he knew it was probably due to the corridor manipulation, he still should have been back by now. Szayel even told him to hurry and he was taking much longer than when he'd told the sixth espada to take his time in changing while he was with that ryoka boy. Not that he really wanted Grimmjaw to see him like this but the unruly teal-haired espada was likely to let him go sooner than anyone else that would enter the facility.

As promised, Szayel returned in a matter of minutes and much less flustered than when he left.

"Well?" Ulquiorra prompted.

"Oh, everything is fine. I fixed the corridors and personally apologized to Aizen-sama. He was surprisingly understanding about the whole situation."

"The whole situation?" Ulquiorra repeated, feeling the blush he'd managed to tame while he was alone quickly returning.

"Well, of course. If I was going to dodge the bullet for irritating Aizen-sama I had to tell him exactly what happened. You know how he is. Only honesty saved my ass." He paused and looked at his two faccion, lifeless on the floor. "Did you have to kill them?

"They refused to release me. I told them what would happen and they chose death."

"Those two were smarter than I thought," he commented, kicking them aside as he made his way back to his subject. "Now…where were we?" He carefully ran his fingers up and down Ulquiorra's shaft, now slick with his own precum.

Ulquiorra growled and moaned at the same time. Those teasing fingers felt too damn good. At the same time, they were only adding to the already intense pressure that had built up in his groin. "Damn it! How much longer are you going to tease me?" he finally asked.

"You want me to make you orgasm?" Szayel asked knowingly.

Ulquiorra hesitated. Of course he did, but he wasn't so desperate as to beg for it…yet.

Szayel didn't wait for an answer before crawling up the foot of the table and wrapping his lips around the head of his comrade's throbbing erection, making a satisfied humming sound as he swirled his tongue around the slit.

Ulquiorra gasped and felt his vision blur. That mouth of his cock shouldn't have felt so ridiculously good. He couldn't think straight and he could feel Szayel's careful hands begin to message his shaft and balls. The pressure was building, building, building. He could feel himself getting closer, closer… "Damn it Szayel, make me cum!" he finally said through gritted teeth.

Szayel looked up at him through hooded, 'as you wish' eyes and began to suck the length into his mouth and then into his throat.

"You are such a fuckin' whore, you know that?" Ulquiorra managed to insult before the head in his lap began to bob up and down. After that, it was just guttural moans and groans that lasted only a few minutes before he felt his body shudder and a sensation similar to cumming but without the release. The cock ring, damn it. In the heat, he'd momentarily forgotten about it.

Szayel withdrew and licked his lips as he watched the forth espada's chest heave with great gasps for air.

"You…bastard…"

"You just said you wanted to orgasm. You didn't say anything about ejaculation," the scientist told him in a 'tisk-tisk' sort of tone.

Enraged, Ulquiorra once again fought against his bindings only to receive the same result as before.

Szayel waited with unnerving patience for the superiorly ranked arancar to wear himself out again before dismounting and continuing to record his findings. "You're temperature's risen again. Even a warmer-blooded individual would be feeling the effects of that by now." He brought his face even with Ulquiorra's erection and made a sound of impressed awe, "Waaa!" he nearly squealed, "Just look at it! It's even more engorged than before. I didn't think that was possible." He was as giddy as a school girl.

Ulquiorra's blush deepened. "Me either," he grumbled as a small portion of his coherence rejoined him. His head was spinning and his cock was throbbing even harder than before. The pain was almost enough to bring a tear to his eye. When it came to sex, Ulquiorra wasn't exactly greedy. One good fuck was all he really looked for, any more than that usually seemed unnecessary and anything close to this was obviously outrageous.

"You are, by far, my best catch yet," he bragged in a husky voice. He was pleased to see Ulquiorra still reacted to the sweet words. This time his lower lip twitched ever so slightly in response.

"How many others have you done this to?"

"Now, that's a rather private matter. Would you like it if I told others about our time spent together," he made it sound like it was some sort of date.

"Tell me and I might not kill you," Ulquiorra's scathing tone returned.

"We both know you won't kill me. Honestly, I didn't expect you to resort to empty threats…at least so soon. Perhaps I will have to make this shorter than I expected…" he waited for his subject's sigh of relief before finishing, "if you're going to break that easily."

"What did you say?" Ulquiorra seethed at the insinuation.

Szayel shrugged and turned away from the table, resting his back against it. He didn't look at the arancar on the table but allowed him a good side-view of his face if he chose to look. "Grimmjaw lasted much longer…but he got the hollow threats on my life out of the way right off the bat," he continued as though he was only speaking to himself. "But that doesn't necessarily mean he'll start bargaining any time soon…" he grumbled in frustration.

"Are you retarded? It's not that I can't take whatever you can dish out. It's that I can't stand to have you doing these…things to me. You are a subordinate and you should behave as such!" Ulquiorra blurted out.

The sudden shouting interrupted Szayel's train of thought. "You're rather loud all of a sudden…are you angry because I was ignoring you? I'm very sorry," he turned with a mischievous grin, "I was just trying to figure out the best way to proceed but, if you're impatient, I guess I'll just have to go with my gut instinct. It rarely fails me but I enjoy taking a moment to reason things out, it brings me great pleasure."

Ulquiorra sudden regretted drawing the scientist's attention back to himself so suddenly but he had to say something. He couldn't just lie there and listen to the eighth insult him like that. He tried to distract him again. "So, who else? Tell me."

Szayel sighed, "You just won't let that go, will you? Out of the espada, the only others I've gotten to examine this closely are Grimmjaw and Norita. I could have had
Yami if I wanted but he's so un-complicated that I didn't think he'd be worth the time and effort. I got really close to Nel once, but Norita ruined that one for me. I've honestly lost track of the lesser hollows that have been on this table. I really need to get one of our more powerful females in here. I'm sure that would prove most interesting. If they are anything like their human counter-parts, as they should be in nearly every physical respect, even one would be most fascinating. Sadly, Haible refuses to lend herself or one of her subordinates to me for even an hour," wined as he began toying with Ulquiorra's nipples once again.

The fair espada shuddered at the feathery soft touches that danced along his upper body, his sense of touch heightened to a ridiculous extreme by the hormones coursing through his veins. "She knows that even if you agree to only keep them here for an hour that it will last much longer than that."

Szayel smiled warmly, "Am I that easy to read?" Of course, he already knew that in these sort of matters, it was difficult for the eighth espada to hide his true nature. "I must say, I thought that getting Norita in here was probably the easiest. Since he has a hole through his brain, it really required very little effort. However, you seemed to just land right in my lap. I must have very good luck." Szayel moved to the head of the table and began playing with Ulquiorra's hair, taking the strands stuck to his face with sweat and brushing them aside. As he did, he took a moment to look down into Ulquiorra's emerald eyes. They were usually so sharp and clear, obviously taking stock of and judging everything they saw. Now they were glazed with lust and he was clearly having difficulty focusing.

Ulquiorra was noticing the same thing and was messing with his perceptions. All he could seem to do was stare back up into those blood-orange eyes as they seemed to bore deep into his thoughts. If he had been just a little more lucid, he would have realized that his actions and words were predictable more because of the state and situation that he'd been forced into than because the scientist had him so completely figured out. That was the moment that Ulquiorra started wishing that he had been drugged. At least then he wouldn't be totally responsible for the ways that his mind and body were betraying him. However, now he seemed to be entranced by his captor. Stockholm Syndrome perhaps? No, because he knew that as soon as he was reunited with his freedom of movement, he would most certainly tear the eighth espada apart. Szayel was right about one thing, he would not kill the researcher…unless he got expressed permission from their master, who would most likely only tolerate a severe beating at the very best.

"You are absolutely stunning," Szayel suddenly said after a long moment of contemplative silence.

Ulquiorra felt his stomach knot-up even more at the sweet words. "Why do you keep talking like that?"

Szayel leaned down and whispered in a husky voice, "I think we both know why…or are you so deep in denial about your own personal preferences that you're not ready to admit what you like and tell me what you want?"

"Why should I tell you what I like or dislike? You're just going to do whatever interests you, regardless," Ulquiorra spat.

"If I know what you like then I won't be as inclined to try other things," he leaned even further forward to tease the outer edge of the hollow at the base of his subject's throat with his mouth.

There was his opening, as wide as he was ever going to get. The eighth espada's throat was mere millimeters from his lips. He didn't even need to think about it. Immediately, he raised his head, his teeth going straight for the windpipe. However, he was only allowed to graze that delicate flesh before his jaw clamped shut on nothing, making a painfully loud clicking sound.

Szayel giggled a little, "You're slow today."

Ulquiorra growled and gnashed his teeth.

"And so is Grimmjaw," he suddenly remembered the sixth, on a mission to retrieve Ulquiorra a fresh uniform.

"You did create quite the labyrinth earlier," the fourth grumbled.

"But I expected him to return shortly after I fixed everything. I thought he would be back by now," he sounded disappointed.

Ulquiorra caught the change in the other arancar's tone and eyed him with even more suspicion than before, if you can believe that is at all possible.

Szayel shrugged and his hands set to work on fastening the only restraint on the table that he left undone in the initial encounter. Normally, it would have gone around an individual's neck. Instead, he laced it through the fourth espada and fastened, making raising his head much more difficult that before. "I was really hoping that you'd be nicer when I bared my throat to you. It was a gesture of trust and you violated that." He sounded genuinely hurt as he crawled up onto the table, not stopping until his face was even with Ulquiorra's erection once again and, without so much as a word, he began licking.

The fourth espada, once again beneath his taller comrade, was now faced with Szayel's only partially erect length, as it began to bulge within his uniform, instead of his milky throat. At first, he was a little disturbed at blatant display of his captor's arousal. Though, he knew he shouldn't have been. He knew even before this encounter just how much Szayel tended to enjoy his experiments. This was just a new and largely unwanted perspective on that thought. Just as that wicked tongue started lapping leisurely at his length, something else occurred to him in the shudder and moan that followed. The researcher was only partially erect while he was still painfully hard. He felt a part of himself grow offended by the fact that Szayel, in spite of all his sweet words, only found this mildly exciting. Somewhere in the back of his mind he wondered, just how much would it take for Szayel to really get into it?

That was as far as he got before the pink-haired espada took the whole of him into his mouth and began to hum.

"Szayel…" Ulquiorra whined.

The scientist made a sound of acknowledgement without stopping his administrations.

"Take that thing off of me," he tried to command but it just wouldn't come out right.

Szayel popped off for a moment to actually speak this time, "Oh, this?" he asked innocently as he twisted the metal ring around the base of Ulquiorra's cock, moving it neither up nor down.

"Yesssss….that! Take it off!"

"Why would I do a thing like that? That doesn't make any sense at all," the pink-haired espada teased.

"It hurts…I need to come," he finally admitted and was rewarded with the sight of Szayel's cock giving the slightest movement as it too became further engorged.

At that Szayel tried to swallow Ulquiorra completely and was largely successful. As he did so, he also reached up a hand to play with his balls. The reaction was so intense, he was sure that Ulquiorra had finally started to let go of his inhibitions. His back arched off the table as he tried to force more of himself into that delicious mouth and he gave a moan so heated that even Szayel blushed at the sound of it.

Before he could really process what was happening to him, Ulquiorra felt himself rushing toward orgasm once. He couldn't believe this was happening again. His breath came in great pants as he squeezed his eyes shut as tight as he could. There was nothing he could do, no resistance left to offer. He felt himself cum hard, even harder than the first time…or the second. Wait, was he at three already today? The very idea made his head spin even faster. But, as predicted, Szayel did not remove the ring, only providing him with a false release which served to make the situation even more desperate.

Before he could think, Szayel had gracefully dismounted and was scratching frantically at his clipboard. As his eyes began to regain their focus, he saw Szayel smiling warmly down at him. "What?" he snarled.

Szayel's fingers wiped something from his cheek before bringing it before his face to see. There was a small drop of moisture. "Do you know what this is? You had your eyes so firmly shut that you actually made yourself cry." He awed, tasting that one before gathering the other two in a small vile.

Once again, Ulquiorra felt rage fill him but he was too high-strung to do anything about it but weakly thrash about while making menacing stares.

The scientist didn't wait for him to stop this time before wrapping his hand around the overly engorged length to begin messaging. Ulquiorra gasped at the contact. Even those careful touches felt as intense as the strongest grip "Damn it," he hissed.

"My jaw's a little sore, I hope this is okay," Szayel informed apologetically.

"Take…it…off…" Ulquiorra managed through gritted teeth.

Szayel ignored him in favor of checking his temperature once again. He made no remarks on it this time but he did stick it back in rather quickly and with much more force than any of the other times.

The fourth espada gave a heated gasp at the intrusion, now even more intrusive than before as it wiggled around and occasionally brushed that sensitive bundle of nerves inside him. It made his vision blur around the edges and body squirm uncontrollably.

Szayel giggled, "I didn't know that you found being penetrated so enjoyable. Here," he removed his hand from Ulquiorra's cock and began licking his fingers, obviously making a show of it. He licked from palm to tip on his index and middle fingers before wrapping his tongue around each one, making sure they were dripping with saliva. "I am sorry for using such crude lubrication…but if I use my famous concoction, you may very well go mad with desire," he informed while withdrawing the thermometer. It was clear how badly he wanted to lube up the fourth with his aphrodisiac oil and just how much self-control it took to repressed that urge.

Ulquiorra's eyes fluttered and rolled as his back arched and his mouth gaped open in a silent moan. Szayel, with no sense of hesitation, only single-minded purpose had stuck his long, slender fingers straight inside him, hitting his prostate with out error.

"If…if not going to…" he found it difficult to speak and when the researcher began to message, rather than just prod, he lost his words.

"If I'm not going to what?" Szayel prompted in a sickeningly sweet voice.

Ulquiorra didn't hear him, or if he did, it didn't register enough for him to form a response. To was too lost in the unyielding sea of sensation that Szayel was providing him. The fourth felt his body moving of his volition, trying to ride the fingers that messaged the overly sensitive spot deep within him.

"This technique his called 'milking the prostate'. Usually, it takes quite a while but with as over stimulated as you are," Szayel didn't get the opportunity to finish his unnecessary explanation before Ulquiorra felt the surge of another orgasm overtake his body, "you should climax with a fair amount of ease." The scientist laughed just a little at just how easy it was. In his past experiments, he had not teased his subject to such a desperate state before attempting the technique. Rather, it had been one of the first things he'd tried in an attempt to see just how much stimulation it would take to force an orgasm in that manner.

Just as Ulquiorra gave the horse cry signaling his false peak, Grimmjaw burst into the facility. He'd been nearly there already but when he heard the strangled sounds that his partner was making, he quickened his pace and arrived just in time to see Ulquiorra trying to come. He was taken aback by the sight. Szayel was hardly touching him, save the fingers lodged inside him, and his erection throbbed untouched in the open, sterile air of the laboratory. His entire body had a rosy flush that looked odd on the porcelain skin of the fourth espada and his entire person held an unprecedented amount of tension. It looked like every muscle in his body was about to tear itself apart. Grimmjaw couldn't help but be taken in by the sight it both captivated and disturbed him. There was one other feeling that he couldn't identify. It was a strange mix of protective pity and defensive anger. Suddenly, he felt guilty for abandoning his comrade to be violated to such an extreme and he needed to do something about it. However, he knew that Ulquiorra's pride would never allow him forgive Grimmjaw for any sort of rescue so he had to do it just right.

All this was lost on the fourth espada who was starting to black out after his third false release. His head rolled from side to side and he was mumbling incoherently as his vision began to fade. He barely felt his comrade withdraw as his consciousness faded. He didn't even notice the arrival of his original lover.

"Ah, Grimmjaw, you've finally returned." Szayel was wiping off his hand as he spoke.

"Yeah," the sixth distractedly replied. As much as he disliked seeing his partner like that, it was enticing just the same. "Are you done with him yet?" he asked as he set the clean uniform on the table next to the one Ulquiorra lay on.

"Nearly. I was hoping you would return sooner. I thought he might like it if you gave him his actual release," Szayel replied thoughtfully.

Grimmjaw was a little surprised by that but didn't argue.

"I'm glad to see you're on board. Help me turn him around so you can get the job done," he instructed as he began to unbind his subject.

The sixth gave a confused look. He saw no reason why moving him was at all necessary for giving him what he so obviously needed.

Szayel sensed his comrade's hesitation. "Come on, before he wakes up. He won't be out for long," he encouraged.

Grimmjaw reluctantly complied, helping Szayel flip the unconscious fourth espada onto his stomach.

When Ulquiorra finally began to stir, he found he was no longer lying on his back but rather on his knees and elbows but still secured to the table. This allowed much more freedom of movement but left him feeling even more vulnerable than before he blacked out. He growled, "What is the meaning of this? Release me!" His entire body ached, especially his cock, which was still painfully constricted. In fact, he quickly realized that it wasn't the change in his position that caused him to wake but the fact that his member hurt so terribly bad.

"Ah, I see you've awoken…" Szayel gave him a disturbingly warm smile, "and your Grimmy is back so we can finish up."

It was only then that he noticed the presence of his lover. "Grimm-ah!" he didn't get to finish the name because he could feel his cock being gently stroked by large callused hands.

The sixth marveled at the way the normally fair-skinned arancar shuddered at the touches. "Let's do this," he stated confidently.

"By all means," Szayel urged as he took a step back to give them some room.

Ulquiorra felt more than saw Grimmjaw climb up onto the table and settle in behind him.

Grimmjaw took a moment to free his erection, which had returned at the sight of his incapacitated and aroused comrade, before sliding into his anxious opening. He groaned at the tight heat, even hotter than he was used to and bent over to cover Ulquiorra's shaking body with his own.

The green-eyed arancar shivered at the feeling of his partner's breath in his ear as he spoke.

"Don't worry. This will all be over soon," Grimmjaw tried to soothe as he ran his fingers through Ulquiorra's sweat-dampened hair.

The fourth espada growled at the kind words. "Just get it over with!"

"I've never seen you this impatient…I rather like it," Grimmjaw teased as he began to thrust into his comrade. Ulquiorra was so hot and responsive that he knew he wouldn't last too long but he would enjoy it while it lasted.

Ulquiorra didn't hear him, being fucked like that was too much for his senses and he couldn't concentrate even if he tried. He only vaguely recognized the sounds of pleasure that echoed through the facility as his own. It was probably better that way because if he could hear them, they would have caused his inhibitions to return.

It didn't take long for either of the arancar on the dissection table to forget about the third in the room who happened to be writing as quickly as he possibly could ever little detail that he observed. This was a goldmine for him and he would be damned if he was going to miss a single thing. He was especially intrigued by the fact that Ulquiorra seemed to have no concern for resisting the sixth instead he was pushing back with what little movement he was allowed with total abandon. He couldn't help thinking that they looked beautiful like that but would never share that thought with either of them.

The feeling of Grimmjaw's tongue tracing the scar on his neck brought him back to reality enough to speak, if only barely, "Grimm…take that thing off me…please," the last word was barely a whisper but he knew it was heard.

Grimmjaw gave the slightest chuckle. "I have a better idea…" He didn't elaborate before he felt Ulquiorra's body convulse with another phantom release, causing him to lose himself inside his partner with a loud groan.

"GOD DAMNIT!!" Ulquiorra yelled in frustration, smacking his head hard against the table.

"Shhh…" Grimmjaw soothed, once again running his fingers through the dark, messy hair of his lover and without another word, he hopped off the table and tackled Szayel.

The scientist yelped in surprise. "Grimmjaw, what are you doing?"

"You are too cruel to your superiors. You should be more careful," he informed, his tone scathing as he bashed the eighth's head against the side of the table, making sure that Ulquiorra could see everything.

Szayel flailed and fought to get away but the grip that Grimmjaw had on him was too strong and he could not break away.

Ulquiorra relished the frantic look on the pink-haired arancar's face.

With Szayel sufficiently stunned, Grimmjaw held on to him with one hand and used his free hand to free his lover.

The fourth espada stretched his limbs leisurely before helping Grimmjaw hoist the eighth onto his own table.

"How do you want him?" Grimmjaw asked with a mischievous glint in his eye.

"On his hands and knees, how he belongs," Ulquiorra answered, fastening the researcher's wrists with the thin leather straps.

Szayel laughed nervously, "What do you plan to do? You can't do anything to me that I haven't already done to myself," he tried to coax.

Ulquiorra scoffed but didn't reply. He simply got back up onto the table. Swiftly, he lifted Szayel's knees, causing him to lose what little balance his position provided and smack his head on the table again, this time causing blood to run freely from his nose. No one said word as Ulquiorra began to fuck him wheelbarrow style.

Szayel wished he could see Ulquiorra as he rode him, betting the expression on the fourth's face would have been priceless. Grimmjaw, however, could see everything and though he wasn't exactly fond of the idea of his lover drilling another into a table, it was the very least that Ulquiorra deserved after all he'd been put through.

"You know, you can take that ring off any time now," Szayel reminded, feeling the dry penetration beginning to get to him and he winced.

"I don't mind it so much now," Ulquiorra's tone was chiding between ragged breaths. He didn't wait too much longer to unclasp the ring at the base of his cock, immediately spilling several orgasm's worth of cum into his receptacle, before dropping the eighth unceremoniously and climbing off the table for the final time. "There's your sample," Ulquiorra spat.

Szayel gave a defeated grumble as he looked down between his legs to see blood and semen running down his thighs.

The fourth was dressed in a matter of moments. "Come on Grimmjaw, let's go."

Grimmjaw nodded and they left together, leaving the scientist strapped to his own table.

Once they were out of the eighth's realm, Ulquiorra stumbled and actually allowed Grimmjaw to catch him without complaint.

"You're a goddamn mess," Grimmjaw needlessly informed as he gathered his partner into his arms.

Ulquiorra fought being picked up but he was so worn that it wasn't much of a fight.

"Stop fussing. Just let me do this," Grimmjaw told him in an even tone before carrying him to his realm to bathe him.

The fourth barely gave a small, "Thank you," followed by a quick peck on the cheek before they fell asleep and slept very soundly together that evening.

Neither gave a second thought to Szayel after they left him. What was done was done and no one could do anything about it but hope that whatever the eighth might have learned could be put to good use.

Szayel, on the other hand, was stuck on his table for quite some time after they left.

Shortly after watching the sixth and the fourth leave, one of Szayel's faccion gathered the courage to enter the laboratory.

"Good, let me go," he ordered as soon as he saw his subordinate.

The faccion hesitated.

"What are you waiting for?"

"Szayel-sama said not to release anyone under any circumstance short of a direct order from Aizen-sama," it reminded.

"You fool! I didn't mean me!" he yelled angrily.

The faccion looked at the tank where his fellow faccion now resided and then back to his master. "I'm sorry!" he squeaked before running out of the lab.

It took another three hours before Szayel could gather enough raietsu to break the bindings.
