On The Cusp
Chapter 1

Soft skin against silky sheets. Warm air blowing gently overhead from the whirring fan in the corner of the room. The near constant, comforting sound of late-night traffic buzzing along eleven stories below. 

A calloused finger traced lightly up and down his stomach, matching the hard lines of his muscles as he breathed steadily in and out. It was dark in his room, even with the moon shining brightly outside. His eyes followed the faint outline of the finger back and forth as it moved higher up his stomach… then lower… then higher… then lower… then lower… then lower…

That familiar, pleasant tingling began to course through him. He shifted under the sheets, steady breathing turning sharp at the sensations bubbling up within him. A moan passed through clenched teeth as he placed his hand on the one snaking its way between his hairy, muscular thighs now. The skin of the hand was warm and thick and…oddly textured, with slight raised and lowers irregular spots covering it all. The tendons and muscles underneath it flexed as he felt thick fingers wrap around his half hard length, causing another, louder moan to burst from his mouth. 

Things felt even more strange to him now. This wasn’t normal but… he felt good—really good, actually— which seemed to be the only thing that mattered in the moment. But that skin… it was so strange. So alien. He shuddered as he felt a thick finger flick over the tip, smearing sticky precum all around the head of his shaft, his legs twitching and moving back and forth under the sheets. His own grip on the alien hand was now moving further up the broad arm of his strange bedfellow. 

He felt more muscle. More texture. More warmth. He was running his hand up further now, feeling a broad shoulder, massive really. Enormous. That texture beneath his fingers seemed to thicken along with the muscles and skin as his shaft was pumped steadily, that pleasure growing sharper with each movement. Three distinctly thick fingers were wrapped around his member now, tightening and loosening with masterful control as his arousal grew and grew. 

He gasped out and thrust his hips into the alien touch, groaning lewdly as he moved closer to the source of that warmth beside him, until he was right up against it. The body was thick and powerful and… huge. Absolutely dwarfing his own and yet… the pleasure continued to mount. He leaned in and placed a kiss against that strange skin, flicking his tongue out and tasting it. Salty sweat. Musk. A certain masculine, earthy tone he couldn’t quite place. It didn’t matter though because he was thrusting his hips against the skin now, intertwining his legs with the much larger ones of his mysterious lover. 

He was practically screaming now as he shaft was squeezed so perfectly, so wonderfully by those thick fingers. The end was in sight now, his body faltering as he twitched and shuddered in anticipation. He moved his hand from the massive shoulder it had been gripping and found… a similarly textured head atop it. The skin felt softer there, slightly smoother and more akin to his own. He ran his fingers forward and felt a cheek… then a strong jaw… his thumb and forefinger followed the ridges and bumps until he was cupping his lovers face in one hand, his eyes desperate to see any details. 

With rapid fire thrusts, he felt himself begin to lose control as he jackhammered against his giant lover, feeling those thick fingers pumping away at his aching shaft as he was about to give into release. 

The moon seemed to shine brighter and the room filled with its glow as he opened his eyes and saw bright, golden irises staring back at his, familiar eyes surrounded by deep green skin and loving, playful smirk. 

That was all he could process as the dam broke within him and he cried out into the moonlight, his shaft pumping strongly between his legs as he felt—

An alarm buzzed loudly beside Casey’s bed while he jolted away and fumbled beneath his sheets. 

“Shut up… shut up… shut up!” 

He groaned as he threw himself to the side of his bed and slammed his fist down on the incessant plastic box. The buzzing stopped and he sighed with relief. 

Casey leaned back against his pillow, squinting blearily at the early morning sunlight streaming through the tiny window in his room. Slowly, his mind adjusted itself back to reality, shaking off the fleeting images of the dream it’d created. He scrunched up his face, trying to remember more details. For him, even the pleasurable dreams usually had a difficult time sticking around longer than a few minutes before they were lost completely. 

He’d been with someone. Another guy, obviously. That was always the case with his more sexually charged dreams. But it was the same guy again. Same as it always was nowadays. He’d been getting the most amazing handjob and it had ended just as he was about to—

Casey paused for a moment and looked down between his legs before he groaned to himself. 

“Godammit…”

He pulled the covers back, revealing a damp, sticky mess in splotches across his slate gray sheets. The pungent scent of his release filled the air around him instantly and he shook his head slowly.

“Can’t even go one night with clean sheets anymore. What the hell’s wrong with me?” 

Suddenly, his phone buzzed rapidly beside his alarm clock and the screen lit up with a message. He took one more glance at the sheets and huffed before rolling out of bed and standing up slowly, stretching his arms up and yawning softly. With one hand he yanked the sheets off the old queen mattress and tucked them under his arm while the other hand reached for his phone, pulling it from its charging cable as he ambled naked from his small room. 

Blinking sleep from his eyes he glanced down at the screen of his phone and flicked the notification over, scanning the text while he stopped in front of the ancient washer/dryer unit and threw his dirty sheets inside. 

R: hey idiot. get up. don’s got some stuff he needs your help with today after training. experiments in his lab. hopefully you won’t die. then we’re goin out on patrol tonight. and fearless has some sort of new lead or some shit he wants to check out in the warehouse district. I think its pointless but i'd rather have you with me than be stuck searching abandoned buildings with golden boy. lemme know when yer on yer way	

Casey grinned at his phone and tapped a quick reply back as he walked into the bathroom and turned the shower on.

C: be there in an hour. tell don itd better not be anything with that stupid brainwave reader again. thing was so annoying to wear and it didnt even work. also. u want donuts? shops on my way down there. Splinter likes old fashioned right? 	

He hit the send button as the cold water from the shower turned warm then hot within a few seconds. Casey flicked his finger across the screen and turned on a podcast he’d been listening to last night. Something about behind the scenes on the newest superhero movie. He wasn’t all that interested in it but he liked to have some background noise to ignore when he showered. 

The water was scalding now, just the way he liked it. Stepping into the shower, he let the stream cascade down on top of him, warming his body and rapidly steaming up the tiny bathroom. The voices from his phone blended into the background along with the constant stream of water to create an odd sort of white noise. For Casey though, it was the only way he could clear his head. 

Last night had been a blur of training sessions, low-stakes criminal tailing, and a whole lot of waiting around on random rooftops in Chinatown, aching for something to pop up on Donnie’s scanner. The turtles and he had been trying to track down a new supply chain of mutagen that was being funneled into New York City. They’d spotted members of the Foot clan moving shipments in cargo trucks all across Chinatown the past few weeks, but somehow they always seemed to change locations each day. 

They’d managed to get a tracker onto one of the cases before it was loaded onto one of the trucks, but the signal had been lost almost immediately after the doors closed. The Foot were being a lot more careful this time around, so something big must’ve been going on. Something more dangerous than usual. But until he and the turtles could figure out exactly what was happening, nightly patrols focused on simply trying to find the Foot’s new base of operations in the city. If they could find that, then maybe they could stop their operations for good. 

He sighed as he felt himself relax under the heat and steady stream raining down on him. Lifting a shoulder, he rolled it backward completely a few times, feeling several pops and cracks randomly throughout as he rotated it. Fighting the Foot was hard work and despite his own best interests, he’d taken more hits than he’d care to think about. He was young, just 25, and had been in great health until he’d fallen in with the turtles and decided to stick around. 

Now though, he was bruised and toughened, having quickly accrued a lifetime’s worth of battle scars in the course of just a few years. Fighting ninjas and Purple Dragons and mutants almost every night will tend to do that to anyone, and he was just a human. The turtles themselves had even more to show for their efforts, a fact that Raph was always willing to bring up in front of Casey like it was some rite of passage in his eyes. 

Grinning to himself, he slowly began to wash his body methodically. Face, chest, stomach, back, crotch, ass, legs, feet. It was the same every time he took a shower, ever since he’d been a kid, though he took extra care to work around his dick and stomach area. They’d never said anything about it, but he knew the turtles had significantly more sensitive noses than humans did, and the last thing he wanted was any of them to find out he’d woken up covered in jizz. 

That’s not a conversation I wanna have first thing in the morning, he thought to himself as he continued to soak for a few more minutes. 

With a sigh, Casey turned the water off and stepped out of the shower, dripping onto the thick towel on the tiled floor as he leaned over and began to wipe himself down. A few minutes later and he’d brushed his teeth and was dressed as comfortably as he could manage while running low on clean-ish clothing. The black tank top that he’d only worn twice in the last week and a pair of torn but sturdy blue jeans with a belt would have to do for now. Luckily he knew he had a change of clothes at the lair in case he needed any after their night was over. 

Giving one last glance around the apartment, Casey grabbed his phone, wallet, and keys and headed out the door, closing it sharply behind him and locking the deadbolt in one smooth motion. 

As he turned and walked steadily down the cramped hallway and waited for the elevator to arrive, he couldn’t shake the image from his dream, the one part that had managed to stay with him past waking—the one thing that had been plaguing his dreams for the past three years since he’d found the turtles: a pair of golden eyes staring back at his and the feeling of bliss coursing through him. 

He shuddered and rolled his shoulder absentmindedly as he stepped into the small elevator and jabbed at the ground floor button, unable to help the subtly pleasant tingle in his crotch as he adjusted himself slightly while the doors closed. He knew he needed to do something about it soon, needed to either put it to rest or just come clean about it, but today really wasn’t the right time, not with all this new Foot activity they’d been trying to figure out and… he wasn’t sure if that time would ever truly come. Or if he really wanted it to.

As the elevator finally began to descend, Casey closed his eyes and tried to imagine himself in a normal world, a world without mutant turtles, a world without nightly fights with ninjas, and a world without this new, constant questioning of his own sanity…. But that world didn’t exist and it never would. Even if it did, knowing what he knew about himself now, he couldn’t imagine ever truly wanting to live in it. So he’d just have to deal with the one he had, and all the problems he had because of it. 

The elevator dinged at the ground floor as the doors opened up and he took a step out, continuing on through the grimey lobby of the ancient apartment complex he lived in. With a shove against the hard metal of the entrance door, he pushed himself outside and into the early morning sunlight that had painted red and orange colors across the clear blue sky of Brooklyn. He huffed and then started the long walk towards the subway.

It was gonna be a long ass day and an even longer night. 

Just one of many for Casey Jones as of late.
