I wrote a story. =D
Not all that graphic, but proceed with caution since it still deals with potentially disturbing content.
Byakuya Kuchiki took large, quick strides down the hallway of his manor home. He was heading towards his basement, where a young blond boy who desperately needed to be a taught a lesson about his place in the pecking order was waiting for him. Byakuya's previous attempts at drilling the much-deserved lesson into the younger fellow's head had failed miserably, but not this time. Nobody would be allowed to defy Byakuya for long. This time, the lesson would be drilled into Russell Tringham's head indeed.
...Heh.
When Byakuya reached his large basement, he opened the door so slowly that it creaked. The dark-haired noodle man was very much an imposing figure, a shadow lit only by the bright white light from the corridor behind him, as all the lights in the basement were currently off despite the two (barely) living creatures chained up inside it.
The first was a man in his mid-twenties, naked save for a pair of torn red boxer shorts hanging around his knees. He had long white hair that had glistened once but now was dirty, oily and scraggly for the lack of being washed in several days. Pegasus J. Crawford was asleep at the moment and far from being Byakuya's main concern at the moment. Lying in a stinking pile of his own filth, Pegasus was past the point of needing to be chain up anymore. He couldn't leave Byakuya's locked basement, anyway.
Russell Tringham was. The totally naked boy was currently chained to the wall by his hands, which were latched firmly behind his back, and his legs were spread firmly apart and above his head, thanks to chain attached to the roof. His face was contorted with rage and pain, and the first thing out of his mouth when he saw Byakuya was an uncharacteristic string of swear words.
Well, actually, it was "............," and then the swear words.
"So, Tringham. You thought you could backtalk me, did you? Foolish boy. You thought you could rebel. You thought you could defy me. Nobody defies me. I'm like the IRS and if Kira tries to list Setsuna as a dependent tax deduction, I'm not going to let him because I'm such a fucking asshole. That's fraud or something -- apparently -- and even though it's only a measly few bucks, I'm going to be the world's biggest douche about it."
"At least," Byakuya added, clearing his throat, "that's what I would do if I was the IRS. But I'm not, so my only concern is you." His lips curled into an unpleasant smile; or they would have, at any rate, if he ever smiled, which he didn't. "You must be taught your place, which is... and always will be... quite literally beneath me."
Pegasus was starting to wake up and watching with interest. He's a pervert like that.
Byakuya picked a drill up off the floor and spent a few seconds just admiring it before he turned it on, closing his eyes and making an affectionate, "Ah," noisy at the lovely purring sound it made. Well, not really purring. More like VVVVVVVVVVRRRRROOOOOOOOOOMSKREEEEEEEEEK or something, but you get the idea.
Russell was trying to move but couldn't. He was gasping and muttering incomprehensibly, sweaty with pain and anger and humiliation and fear. "Who do you think you are?! You can't get away with this!"
"Oh, but I can," Byakuya said icily. "I can do anything I want. You, however, cannot. You and your like live only for my satisfaction... to serve me..." He took in a deep breath. With that, he began bring the whirling drill closer and closer to Russell.
Russell began to urinate uncontrollably. "WHAT THE HELL ARE YOU DOING?! GET...STOP..."
The whirring drill came closer, closer, closer... Russell screamed as it drilled through skin and muscle and bone, puncturing straight into the gray matter of his brain. The pain was searing and the blood was hot dripping down his pale white skin. "NO, STOP. I'M SORRY. I... I... I..."
Byakuya's erection grew and grew until it reached its full five-inch length. (Come on, you guys always knew he was overcompensating.) Russell's mouth hung open as he screamed bloodcurdling scream after bloodcurdling scream until he sagged and stopped breathing or moving at all. Byakuya unzipped his jeans (Yes, he's wearing jeans. STFU.), taking his hardened penis out and, as he slowly removed the drill from the bloody gap in Russell's forehead and turned it off, gently setting it down, he slowly began to insert himself into the gray area.
He had no lube, but this is fantasy and we're pretending brains are lube.
"Brutal," Pegasus commented, before he retched.
"Shut up," said Byakuya.
Russell's brain squished as Byakuya began to pound away at the whole in the boy's skull. Oh, he'd drilled his point in, all right. Byakuya moaned softly, feeling the pleasant sensation of Russell's brain molding and contorting and squishing into mush around his penis. It was better, he reflected, than having his penis in Renji or Pegasus. It was even better than the time he had, quite literally, ripped Rukia a new asshole a la goatse and fucked her in it.
There was a blast of white, sticky cum from Byakuya as he let out one final yell and Russell's body sagged to the floor, Byakuya pulling out, his cock bloody with bits of brain clinging to it. Then Bya shoved a dead rat from the corner up Pegasus's ass ("Oooh!" Pegasus cooed) and left the room, zipping up his pants.
