Smut Warning!

Running as fast as he could, Ichigo nearly faceplanted into a wall. Curses escaped past his lips as he scrambled for balance. The air around him became thick, and the sudden change of spiritual presence in the air made his mind hazy.

What the hell did Mayuri do to him?!

Ichigo groaned as he tried to steady his breaths while running at full speed. He looked up from the ground at his surroundings to find an empty hallway filled with smoke and dust, which made it impossible for him to see where he was going.

"Oi! Seriously?! Are you planning to trap me here forever, you Coward. Show yourself. Damnit!" In an instant, the presence of a figure far behind him appeared.

"Tsk Tsk.. How rude! That's no way to speak to a captain" He could almost hear that irritating smirk from the other end of the room.

Oh, I really wanna kill you now. He thought, his grip on his Zanpaku-to tightened as the urge to attack came, overwhelming his senses. He was tired, frustrated, hungry, dirty, hot, tired of running and hiding.. And most importantly desperate to find an exit to this maze.

This must've been Mayuri's plan! If Kurosaki Ichigo was caught by the mad scientist, it would definitely prove his worth to him and his research.

A cold sweat drenched his skin as the realization settled in on him, making his heart stop. His legs stopped moving, and he felt himself fall face down on the floor, breathing hard.

"Where..— what was that device."

"Well, I'm glad you asked! Because this device can teleport you to another dimension that I created. I call it the Shinkai Dimension."

Ichigo's eyes widened at that. Dimensions? What kind of stupid experiment was Mayuri planning to try out with him? He shuddered to think of the possibilities. This whole thing just got a lot worse than he initially thought.

"Remember, You must run, or else I might catch you!" With those words, Mayuri vanished in a flash of light and It nearly took all of Ichigo's willpower to turn around, sprinting the other way with the man chasing after him.

Fuck, Mayuri was going to be the death of him.

He didn't even know why the man was letting him run for hours in the first place. Mayuri had a reputation for being the most impatient captain, not to mention that half of Ichigo's body felt numb. Despite this, he was somehow able to run as quickly as humanly possible. And, well, Ichigo couldn't care less about the pain. His lungs hurt like crazy because of how fast his heart was beating right now, and he knew that if he didn't keep running and find an escape soon, Mayuri would catch him.

If Ichigo hadn't known better he'd say the guy was having fun. Mayuri was the definition of an eccentric genius; there were always things to learn, experiments to conduct, discoveries to uncover. Mayuri liked it when Ichigo showed curiousity about his experiments.

"You know... I really did not want to do this, but these feelings that I have never felt before are just so addicting that I can't help but want to learn more about them and about you."

His eyes widened once again as the reaper appeared in front of him, and his face collided with the other's chest. Pulling back Mayuri's hand reached out to touch his face, tracing over the Intricate patterns decorating his face. His hand moved down slowly until his fingers found the new cut that he had gave him earlier ."Such a beautiful specimen. All for me." Mayuri murmured as his hand traced the outline of the mark. Ichigo flinched at his touch, but didn't move away. He could never move away from those eyes that promised blood, even if how much he wanted to.

"Mayuri.." Ichigo whispered, his voice hoarse. Mayuri looked up at him, his eyes shining with excitement. "What are you doing?"

"I'm trying to understand you, Kurosaki Ichigo." Mayuri said, his voice soft. Ichigo's heart skipped a beat.

How could he have never realized it before? Mayuri was attracted to him. There were times that he wished that Mayuri would take some initiative to actually acknowledge his feelings towards him..but Mayuri was afraid...of rejection? No. No, that's impossible. The man would never say something without thinking thoroughly through it first.

"I can't— Well I.. " Kurotsuichi stumbled as his mind ran on a tangent. He wasn't usually speechless, but his head swam with thoughts at once, all jumbled together as they attempted to form coherent sentences. Finally, he gathered a bunch of them together and managed to string two words together.

"I'm sorry, I can't.."

Mayuri's eyes darkened and he smiled.

"You don't have a choice."

Ichigo moaned, another thrust sending waves of pleasure rippling throughout his body, causing tremors in every part of his body as he reached an Orgasm.

A loud whine escaped from deep within his throat, echoing against the dark sky.

Loosing his remaining self-control, Mayuri gave his cock an experimental lick before

swallowing him down in one smooth motion.

He heard a strangled moan leave the boy's mouth. The reaction was exquisite. So, perfect, Mayuri thought to himself. It was only fair. After all, Kurosaki Ichigo was one of his favorite subjects, he had spent a considerable amount of time examining him.

A small smile touched his mouth when he felt the young man tense beneath him. His hands gripped the boy tightly as he continued to lick and suck. The sounds coming out from Ichigo were pure bliss, he couldn't contain his happiness. He loved watching him. He loved watching how his muscles tensed and relaxed as he pushed down on the cold concrete. It was intoxicating. He needed more.

Ichigo was a trembling mess underneath him, his breathing erratic. He let out a whimper when Mayuri pulled back and moved down to his neck, licking the sensitive area where Ichigo's pulse pulsated wildly, leaving a trail of love bites all over his neck and collarbones. The older man leaned down and bit Ichigo's shoulder. Ichigo hissed in pain.

"Nggh.. Fuck— You sadist—" He groaned, feeling male thrust inside him. He tried to sit up, but his vision was blurred by a wave of nausea. Why was everything blurry? "Don't try to stand up yet, I still need to experiment on you." Mayuri hummed, looking at him with wide, dark eyes.

"You— Gah, Have you gone mad-" Ichigo panted, a loud whine coming out of him when Mayuri began increasing his pace, going agonizingly deep, eliciting a low groan from the young man under him.

"I'll fuck you until you can't— Move, do you understand? " Mayuri growled against Ichigo pinning him down to the floor as he held both of Ichigo's wrists above his head. He could feel Ichigo's arms shaking and twisted beneath him, his body trembling as the pleasurable sensations coursed through him.

A satisfied smirk tugged at his lips as he continued to watch how the young reaper was struggling to remain concious while trying to resist the urges to lie on the floor and succumb completely to his touches.

Mayuri also let out a few moans of his own. Fuck— Ichigo felt amazing! He didn't think he would ever be able to experience such pleasures as what Ichigo was giving him.

The younger man squirmed again and he knew Ichigo was close to having an orgasm with the way his walls clenched and undulated around him, his legs twitching involuntarily and tears were forming in his eyes while moaning louder. Noticing Ichigo's resistance at releasing, Mayuri grabbed ahold of Ichigo's hips and slammed his cock deep into him, his cock hitting a spot inside Ichigo that he knew would send him into ecstasy.

"Nggh!" Ichigo gasped, throwing his head back as he succumbed to a climax.

Both men panted heavily, their chests rising and falling rapidly.

"... Can we go back now?"

Mayuri grinned. "Who said I was done?"
