A Good Scientist
by: Naraku's Dark Soul

“A good scientist should anticipate….” The hand on Szayel’s cock tightened, sending a thrill through his abused body. “…change. Should know that things aren’t always as they seem,” Mayuri continued with a chuckle, slipping a metal ring over the end of Szayel’s straining erection and forcing the well-lubricated thing down the length of his shaft until it pushed against his balls.

Szayel closed his eyes as the other man began attaching wires to the thing, his hands balled into fists at his sides. Although he was grateful that Mayuri had given him the antidote to the mind-altering drug he had been administered during their battle, he was certainly not happy with the outcome.

It was true Mayuri had stabbed him through with his zanpakutou, but it was really just for show. The drug in his system had also worked as a coagulant, stopping him from bleeding to death while the Shinigami was busy elsewhere. The vile man had come back for him when his work was done, taking Szayel back to Soul Society as a prize specimen. He had been there for weeks now, subjected to every kind of experiment imaginable, and so much more. It seemed this captain was as perverted as Szayel himself, perhaps even more so. Under the thin guise of research, he had taken to performing sexual experiments on the Espada.

Szayel shuddered as the other man placed a long, thick probe against his asshole. It was cold against his sensitive skin, obviously metal, and slick with lube. He almost smirked, imagining what kind of excuse the Shinigami would come up with for this. The other man slid the thing far enough inside that it touched his prostate and stopped, connecting wires from the ring around Szayel’s cock to the end of the metal probe. The slight pressure it exerted made Szayel’s cock twitch, made him ache for release, but he didn‘t show it. His already good poker face had been put to the test many times during his captivity, and despite everything, had rarely failed him.

He almost sighed in relief when Mayuri withdrew, opening his eyes to see the other man attaching the trailing wires to a nearby machine. It was an unimaginable humiliation to be on the receiving end of such treatment, especially when the one doing this to him was a Shinigami. The farther the other man was away from him, the better. If Szayel just ignored him, he could imagine that he was back in his own laboratory in Hueco Mundo, could imagine it was Aizen experimenting on him. The mere thought of his master was enough to cause his cock to jerk in excitement. He rolled his eyes, glad Mayuri was otherwise occupied and did not notice his little slip up.

In all his time in the other scientist’s domain, he had yet to see anyone else. It was most strange, and Szayel had concluded he was not in the other’s main laboratory, but a smaller one, most likely private. It made sense considering the “experiments” Mayuri was performing on him and the fact that he was an Espada. If their places were reversed, Szayel would have done the same. There were no limits to the things one could do to a subject in private.

Szayel flexed his wrists. He had never given it much thought before, but it really was quite tiresome being shackled down. Although he was more aroused than he cared to admit, he could still feel the uncomfortable tightness of the reiatsu resistant cuffs keeping him prisoner. The metal encircling all his major joints was thin, but surprisingly strong. Szayel knew his physical strength was sub-par when compared to his mental acuity, but that hadn’t stopped him from trying to break the bonds with brute force. As expected, and despite his best efforts, they had remained firmly in place, not budging an inch. It was all very frustrating, just lying there, but he had grown accustomed to it over time.

There were a few clicking noises as Mayuri finalized the connections between wire and machine, and then the man was back at Szayel’s side, sliding around until he had a good view of the probe buried deep in Szayel’s ass. “A good scientist should have a high pain threshold. There will always be accidents, and these can cause varying degrees of harm to the body,” he crooned, absentmindedly stroking Szayel’s erection as he fiddled with the probe in his ass, attaching several more wires to it.

Szayel ignored the other man’s inane monologue, as he had for the greater portion of their time together. At first he had been his usual self, all dripping sarcasm and witty comebacks, but the more the man droned on about his views on science, the more disgusted Szayel became. It was as if he thought Szayel a mere lab technician, and was trying to educate him. Szayel was not having it. Mayuri might have been a scientist for longer, but in Szayel’s short time as an Arrancar, he had already surpassed the other man in many ways. If not for a mere miscalculation on his part, their places would have been reversed.

He had not spoken in days, and didn’t intend to start now. It was far more prudent to focus his mental facilities on a useful subject, such as devising a plan for his escape. Because escape he would, and oh, would Mayuri be sorry then.

He was busy planning just that and almost had a feasible idea in mind, when the first jolt of electricity from the probe and cock-ring hit him. His reaction was as involuntary as it was immediate, his back bowing as much as the restraints would allow, a surprised groan tearing free from his dry lips. The sensation was short-lived, however, as Mayuri quickly cut the power.

Szayel found himself panting lightly, perspiration gathering on his otherwise pristine brow as Mayuri scribbled down some notes in the pad of paper he was holding. He had almost calmed himself when the second jolt hit him, cutting short all rational thought. This one lasted longer and as it subsided, Szayel felt something inside of him crack.

Mayuri flicked the switch again and as the electricity passed through his body, Szayel could feel his orgasm building. The world went white as the pressure grew in his skull, pleasure so intense it was almost pain rebounding through his body as the crack inside of himself widened. Sightless eyes opened wide and restraints groaning against the sudden surge in his reiatsu, Szayel exploded, his awareness shattering as his release overtook him.

As his mind cleared, Szayel found himself free of the debilitating, reiatsu-resistant cuffs, found himself standing instead of lying down. One glance at the tentacles in place of his feet was all it took to realize that he had somehow broken the mental barrier keeping himself from the rest of his abilities. Zanpakutou were merely extensions of a person’s powers, so it made sense that under extreme duress his had freed him. It was certainly surprising and required much further study, but at a different time. Szayel knew he must act quickly.

Unfurling his wings, Szayel gave the surprised Shinigami a cold smile, black liquid exploding out of his back as he did so. Although Mayuri was quick, his surprise slowed him enough that he was unable to dodge all of the substance. The vile man grimaced as his copy grew next to him. He reached into his sleeve and pulled out a knife, unsuccessfully trying to injure his clone. He struck at its heart, but was met blade-to-blade with the exact same knife.

Standing nearby, Szayel watched as the two exchanged blows, an amused half-smile on his lips. It was one thing to study data, but quite another to have the experience of fighting yourself firsthand.

“Tsk, tsk. A good scientist should know his limits,” Szayel quipped, pointing at Mayuri as he threw some of the vile man’s earlier “advice” back at him. Szayel had certainly heard enough of that to last a lifetime. He sucked in a breath, letting it out slow. It felt so good to be free, but better yet was the fact that he had the upper hand in this battle. Over the course of his time in Mayuri’s care, he had noticed the other man never had his zanpakutou with him. Szayel assumed it was because of what had happened in Hueco Mundo, but it did not matter. Whatever Mayuri intended, he was significantly less equipped to fight without it.

As Shinigami and clone fought, Szayel was busy contemplating his escape from Soul Society. Although his abilities were above par, he was in the middle of the enemy’s territory. He would have to tread carefully to make it home in one piece. This brought his mind back to his current incarnation. Szayel had no idea if he would be able to revert to his previous form after having his release forced on him in such a manner. Eyes narrowed, Szayel came to a decision. He moved forward, propelling himself at Mayuri. On his command, the copy attacked from the other side.

Mayuri dodged the copy’s attack and moved to engage Szayel, grinning all the while. He slashed out with his knife, cutting Szayel’s arm. It was a shallow wound, but stung nonetheless. Szayel quickly stepped back, the clone coming up behind Mayuri for a surprise attack. As expected, this was only partially successful, Mayuri managing to angle his body so the clone’s knife grazed his shoulder. He turned toward the copy, and Szayel grinned, coming up to wrap his wing around the Shinigami.

Before Szayel could finish, a sharp pain exploded in his chest, and he looked down to find Mayuri’s knife buried in his flesh. Eyes wide, he watched as red crept out from the wound. Behind Mayuri, the copy crumpled to the ground.

“Dead or alive, it doesn’t matter to me,” Mayuri said, chuckling, his hand still on the knife’s hilt. For a moment, Szayel stood frozen, and then his eyes narrowed.

“Wha--,” he gasped and collapsed to the ground. Mayuri’s chuckle turned into full-blown laughter as Szayel twitched on the floor. He took a step forward, ready to finish Szayel off, but the copy grabbed him from behind. His laughter abruptly stopped as one of Szayel’s tentacles wrapped itself around his body. “Just…kidding,” Szayel choked out, his vision fading.

“A good scientist knows experiments can have unpredictable results…” The voice and accompanying laughter did not come out of the body on the floor, but from the tentacle holding Mayuri. The Shinigami’s eyes widened at this, the egg inside of him growing, sapping his strength. He wilted, held up not by his own power, but by that of his clone’s. His stomach quickly expanding, he cursed and tried to reach for the knife buried in the fallen Szayel’s chest, but was unsuccessful. Fingers curled in on themselves and skin clung to bones as muscles atrophied, all nutrients in Mayuri’s body being consumed by the growing Szayel. A gurgling hiss announced his death and Szayel’s rebirth, the Espada pushing his way out of Mayuri’s mouth.

The newly reborn Szayel looked from the corpse back to the faux Mayuri and a manic grin overtook his features, his lips spreading wider than he would have thought possible. It was high time to steal all the asshole’s research. But first, a little revenge. By his own volition, he had chosen to return in his unreleased state. It was just as useful to him as his release.

Szayel moved closer to the dead body and stood above it, feet spread a little as he freed his straining cock from his hakama. It seemed that along with his impressive abilities, he had also acquired Mayuri’s unresolved sexual tension. As if he needed more evidence that the other man found “experimenting” on Szayel arousing.

Szayel pumped his cock with one hand, jerking it harshly until he came hard onto the corpse’s dried face, white jets of his semen landing on the shriveled lips and sunken cheeks of his dead captor. He slumped, sighing in satisfaction as the last jet of his come landed in the eye of the corpse. Off to the side, the Mayuri-who-was-not-Mayuri looked on with dull eyes, and Szayel smiled.
