Summary: After several long days of work, Ritsuka is sternly told by Jeanne to take a break...but he can't sit around doing nothing! Too antsy to rest, Ritsuka is about to jump back into the job when Robin shows up at his door, determined to make sure he gets the rest he needs 

This is a commission! 

-

Collapsing onto the couch with a loud sigh, Ritsuka wearily scrubbed a hand over his face. His eyes were burning. There was blurry patches that he couldn’t get rid of, no matter how many times he blinked. How long had he been awake? It felt like it had been a whole week but probably wasn’t any more than 24 hours. He groaned quietly, pressing the heels of his hands to his eyes. So tired…he really should try to get some sleep…but his mind was racing. The doujin was almost done – there was only a couple more days worth of work before this immense project had finally been completed. He would still be working on it right now if Alter hadn’t insisted he take a break. Rolling over onto his side, Ritsuka stared at the blank screen of the TV. He closed his eyes for a few moments then opened them again. He rolled over onto his back then his other side. After staring blankly at the back of the couch for a few moments, he sat upright, spun around and dropped down onto his stomach. That position only lasted for a short moment too before he was tossing and turning, struggling to get into a comfortable position.

It very quickly became apparent that relaxing was only a far-off dream. His legs twitched – refusing to be soothed no matter how much he stretched them. There was a straining pulse of pain in his lower back. His fingers with itching, desperate to be wrapped around a pen or mouse once more. Just lying here, knowing that Alter was still working away without him, it was driving him crazy! Thoughts and ideas of how they could tackle the upcoming sections of the doujin whizzed around inside his head. No matter how much he tried to quiet them, it was no use. There was no way he could relax when there was still so much to be done! Jumping to his feet, Ritsuka darted over to the door, determined to convince Alter to let him keep working until they had finished. He would only be able to relax then.

Ritsuka yanked the door open then jumped back with a startled yelp.

“Yo.” Robin lowered the hand he’d obviously been intending to knock on the door with. Tilting his head slightly, he asked, “Are you alright, Master?”

“Y-You scared me.” Ritsuka sighed, pressing a hand to his chest, “What are you doing here, Robin? Is something wrong?”

“Sorry about that.” Robin stepped forward, slipping into the room. He closed the door behind him with his foot, either not noticing or choosing to ignore Ritsuka’s intent to leave, “Nothing is wrong. I just came to check up on you. Alter said she had made you take a break.”

“She did.” Ritsuka replied cautiously. Had Alter sent Robin to make sure he was actually resting? No, she wouldn’t have taken her attention from the doujin long enough to issue an order like that. Alter probably did tell him but Robin was here on his own accord…which meant, if he wasn’t care with his wording, he might be kept away from his work for longer than he wanted. Shifting his weight from one foot to another, Ritsuka carefully continued, “And I’ve taken it so I’m gonna go back to-“

“Hmmm, nope.” Robin offered the hint of a gentle smile, “You’re staying right here with me.”

He reached up to curl a long, thin hand around the back of Ritsuka’s head, pulling him forward at the same time he was leaning down to press their mouths together in a firm kiss. A nimble, talented tongue easily parted his lips, sliding inside to swipe across his own. The taste of sweet wine spread across his tastebuds. Ritsuka gasped softly, instinctively melting into Robin’s touch. A burst of warmth rolled down his throat, soaring through his chest and stomach until it reached his crotch in a pronounced bubbling of excitement. Ah…he knew exactly what Robin was doing…and it was working. When was the last time they’d even kiss, let alone had sex? It must’ve been days now. A gnawing hunger that he’d only barely kept at bay while he was working came roaring in, dominating his every thought. An intense itch spread out from deep inside him, spreading down his legs and up his torso in a wave of needy tingles.

Pulling away from the kiss with a wet gasp, his face burning with scalding heat, Ritsuka whined, “R-Robin, please…!”

The words had barely gotten out of his mouth when Robin grabbed hold of his arm, pulling him over to the couch. In a smooth, graceful movement that made it feel as though they were dancing, Robin spun him around, pushing him down onto the couch. With the same agility, Robin hopped up as well, shifting his weight between Ritsuka’s legs. Harsh pants tumbled out from between Robin’s parted lips. Two bright spots of red blazed in his handsome face. Hazy lust swam in his cerulean gaze. Pushing up to brush a hungry kiss to the corner of his lips, Robin curled his long, slender fingers around the hem of his pants.

“You don’t wanna go slow, do you, Master?” He cooed, peppering little kisses all over his face.

“No-!” Ritsuka gasped, wrapping his arms loosely around Robin’s slender frame, “Please, Robin!”

“Please what, Master?” Robin slipped down, mouthing along the curve of his throat, “Tell me what ya want.”

Flushing even hotter, the tips of his ears burning, Ritsuka choked out, “F-Fuck me…please…”

“Hmm?” Robin straightened up, a teasing smile tugging at the corners of his lips. He expertly tugged open Ritsuka’s pants without taking his smoldering, playful stare away from his face, “Come on, Master. You can do better than that. Tell me…tell me everything you want.”

Panting raggedly, his heart a rapid thrum against his ribcage, Ritsuka swallowed hard against the dryness in his throat, “Ple…Please…Daddy…fuck me…I-I want…” He reached out with a trembling hand to push it between Robin’s thighs, gently rubbing his palm against the hard, twitching bulge. Robin gasped softly, his thin hips bucking forward to grind against Ritsuka’s hand. A bolt of tingles rushed up his arm, ending up as a burst of fireworks inside his chest. Drool poured into his mouth, pooling underneath his tongue. Inside…he wanted this big thing inside-! He wanted it so badly, he didn’t care if he couldn’t return to work for the entire day, “This…please give me this…Daddy…”

Visibly shuddering, his lazy grin growing even wider, Robin purred, “Aye, that’s what I wanted to hear. Now,” he curled his long fingers underneath Ritsuka’s chin, “focus only one me, yeah?”

“Y-Yes…” Ritsuka replied breathlessly, feeling as though he might burst from excitement.

That was all Robin needed to hear to get moving. Wrenching down Ritsuka’s pants, allowing his throbbing erection to bounce free from his soaked underwear, Robin turned his attention to his shirt next, yanking that off as well. He threw all his clothes aside without a second glance, his hungry gaze roaming shamelessly over Ritsuka’s exposed body. Slipping his long, thin hands underneath his trembling legs, he pushed them up until his knees were at his chest. Pulling one hand away, he spat a large wad of saliva onto his palm and smeared the warm fluid across his twitching hole. Ritsuka gasped, his hips rolling.

Robin yanked open the front of his trousers, shoving a hand inside to slide out his fully rigid, dribbling cock. He wasn’t given any time to bask in the gorgeous sight of that amazing cock. With a harsh breath, Robin shifted forward, pressing the tip of his cock to his hole. He bent down to capture Ritsuka’s mouth in a ravenous, possessive kiss. As his tongue was sliding between his lips, Robin slammed his hips forward, driving his thick cock through the tight ring of muscles. Ritsuka squealed loudly, a violent tremble shaking his body. Immense, bursting pleasure coursed up his spine, slamming into his mind with enough strength to completely wipe away his exhaustion and stress. He came from just that sensation alone, thick ropes of white spraying out of his cock. His mind went completely blanked, soaked with a glittering golden fog that drowned out everything else.

That incredible heat sunk deep into him, spreading him open wide. Robin’s hips banged against the curve of his ass. Letting out a sharp breath through his nose, his thin hands curling around the back of Ritsuka’s head, Robin slipped back just a couple inches so that he could see his face as he began to rapidly thrust forward. Crying out raggedly, clutching at Robin’s shirt, Ritsuka trembled and shook underneath his weight, rolling and bucking his hips in time with his thrusts. Robin’s cock shoved in deep, grinding against the underside of his belly. The friction of the prominent veins rubbing along the interior of his ass threatened to completely unravel him. He welcomed it, raising and rolling his hips to urge Robin’s cock in even deeper. Good…good, good, good-! It felt so incredibly good-! Robin’s cock-! He loved Robin’s cock-! More, more, more, more-! He wanted to be fucked until his ass turned inside out-! Until he couldn’t remember the doujin at all-!

“Gods, it feels so-! Good-!” Robin groaned, “So tight-! Haven’t…heh, haven’t even been playing with yourself, huh?”

“I-!” Ritsuka gasped, tears blurring his vision. He pushed up, clumsily kissing Robin’s smooth lips, “Can’t cum-! Unless it’s…you! Need you, Daddy-! Need your cock-! Please-! Please-! More-! More-!”

“Aye,” Robin panted raggedly, a pleased smile stretched across his flushed face, “I’ll give ya everything you want…! Come here, Master…come here and accept my everything.”

“Yes-! Yes-!” Ritsuka squealed gleefully, stars bursting across his vision. “Inside-! Inside-! Daddy, please-! Wreck me-! Fill-! Stuff me full-!”

“Master…Master-!” Robin gasped.

He lunged down to smash their lips together in another desperate kiss. Ramming his hips forward to completely sheathe his cock inside, Robin moaned loudly into his mouth. A harsh shudder shook his thin body. His length swelled up even bigger inside him, stretching him further open. A heavy torrent of thick, sticky cum poured into him, coating the inner walls of his wall. All the breath whooshed out of Ritsuka’s lungs on a loud scream of delight. Hips straining up off the couch, eyes rolling back into his head, Ritsuka came a second time. Brilliant waves of ecstasy crashed over him, soaring through his nerves in a blistering fire of pleasure. There was no pause, no time given to recover – before the last drip of cum had been squeezed out of Robin’s cock, he was wrenching backwards, grabbing Ritsuka by his hips and rolling him over onto his stomach. Slamming his hands down onto the couch on either sides of his head, Robin started roughly bucking his hips again.

Howling lewdly, tongue hanging out of his mouth, Ritsuka used what leverage he could find to slam back against him, shoving his cock in even deeper. Good-! Good-! He…he was…he was being treated so roughly by Robin-! He was being messed up, stirred up so deep inside-! Loud, wet squelching filled up the room. Sweat drenched his trembling body, rolling down his face and back in fat droplets. Holding tightly onto Robin’s arm, gibbering out incoherent squeals of delight, Ritsuka only made it a few thrusts before he was cumming once more, dirtying the couch underneath him. A near constant hum of pleasure had settled into his body, dominating every inch. His skin blazed with heat and tingles. His toes curled tight. This…this was heaven…pinned underneath Robin’s lithe body, filled to the brim with his amazing cock…the only thing that could make this even better was a belly pumped full of his cum but he got the feeling that was a wish that was going to be granted very soon.

“Gods-!” Robin cursed raggedly. Dropping down to rest his weight on top of Ritsuka, Robin curled his arms tight around his trembling form, squeezing him tight to his chest. The rhythm of his thrusts sped up even more, becoming erratic and graceless, “Master-! Master-! Mas-!”

Burying his face into the curve of his shoulder, Robin came again, shallowly pumping his hips as he added another load to the first. Ritsuka wailed loudly, a delirious grin spread across his messy face. Intense heat spread throughout his belly. So much-! There was so much-! This was only two orgasms in but he…he could already feel his stomach beginning to swell. Had Robin been saving up in preparation for something like this? With Robin’s cock consistently buried inside, only a small amount of his previous orgasm had managed to seep out, leaving the majority of both huge loads inside his belly. Ritsuka giggled drunkenly. More…more, more…he wanted even more-! This wasn’t enough-!

Shakily twisting his head around, Ritsuka beamed up at Robin, wiggling his hips enticingly – not that he needed to but it was always so satisfying to watch Robin’s eyes widen and blaze even brighter with roguish lust as he watched the shameless movement, “More…more, please…Daddy!”

Choking out a harsh breath, Robin moved back. He grabbed hold of Ritsuka’s arm, yanking his upper half up off the couch so he was balanced on his knees. Holding him steady, he kept bucking his hips, fucking his sloppy hole with an energy, enthusiasm that made Ritsuka’s head spin. Drool dribbled down his chin, sliding further along the curve of his throat. His weeping cock swung back and forth between his trembling thighs. His butt smooshed against Robin’s pubic bone. The wet slap of their bodies colliding together intermingled with their moans and gasps, the squelches and squishes of Ritsuka’s cock being used, creating a symphony that echoed through his head. Bouncing back and forth on the couch, every inch of his body humming with the powerful ecstasy of being used as his Daddy’s cocksleeve, Ritsuka came twice more, adding even more of a mess to the one he’d already created, before Robin abruptly yanked him further backwards. Plopping down onto his butt, Robin yanked him into his lap, curling his legs around him. This change of position had the profound effect of pushing him even further down onto Robin’s cock. Robin’s thin hands landed on his chest, groping and squeezing his pecs, pinching and rolling his hardened, sensitive nipples between his calloused fingers.

“D-DADDY-!!” Ritsuka wailed, tongue lolling lewdly out of his mouth. Sharp bursts of tingles rushed out across the surface of his skin. His aching cock twitched. His balls buzzed and hummed. It didn’t feel like he could cum anymore but Robin subtly changed the positioning of his thrusts, grazing against a special spot inside him that brought on a blinding flash of white. Throwing his head back, his teeth tightly clenched together, Ritsuka shrieked loudly as watery threads poured from the slit of his cock. Laughing huskily into his ear, Robin’s nimble hand darted down to curl loosely around his soaking wet length, pumping it teasingly.

“W-Wait, pleash-!!” Ritsuka sobbed, weakly grabbing at Robin’s hand, “Too much-! Too much-! Can’t-!”

“We’re not even close to being done, Master.” Robin panted, “I told ya…I’ll give ya my everything. You want that, don’t ya?”

“Yes…Yes-! Yes-!” Ritsuka whined, nodding shakily. It was almost overwhelming but he did…he wanted everything! All of it! “Please…Daddy! Daddy! Give…give me everything!”

Nipping at the shell of his ear, Robin whispered, “Yes, my Master.”

The last beam of sunlight had long faded away to nothingness by the time Robin slipped his softening cock free from Ritsuka’s sloppy, gaping hole. Moaning weakly, a shudder shaking his already violently trembling body, Ritsuka unconsciously clenched his ass, desperate to keep that heat inside for as long as possible. His hazy, unfocused gaze was glued to the prominent swollen curve of his belly. A dizzy smiled touched his lips. This…this was what he could never get enough of…seeing his stomach become so full of Robin’s seed. He was so full…so warm…it was…heaven…

He was exhausted, worn to the bone but wonderfully, blissfully sated. Sleep tugged seductively at his mind, pulling him closer to tipping into the world of dreams. He could barely keep his eyes open. Still, he tried, fighting against the coy fingers curling around his consciousness as he struggled to focus on Robin. Not yet…he didn’t want to be taken from this warmth, this closeness just yet. Robin tucked his flaccid cock back into his trousers, straightening everything back up then turned to him with a warm smile. He stepped forward, bending down to slip an arm underneath Ritsuka’s knees and around his back. With expected ease, he lifted him up off the couch.

“Should we take a bath, Master?” Robin asked quietly, rubbing his cheek against the top of his head.

“Mmm…” Ritsuka hummed agreeably, melting into Robin’s hold.

“Did it feel good, Master?” Robin inquired, using his foot to open the door. He walked down the hallway towards the bathroom, striding confidently in the dense darkness.

“Yes…” Ritsuka breathed, “It felt amazing…”

“Good. I’m glad.” Robin chuckled softly, “While I admire how hard you’re working, please take a little more time for yourself,” he paused for a moment then laughed again, kissing Ritsuka’s temple, “and for me, alright? It’s been torture, holding myself back over these past few days.”

“I-I’m sorry. It’s…it’s been hard for me too.” Ritsuka snuggled even closer to Robin, “I promise, I’ll make more time for both of us from now on.”

“Please do. Now, let’s get you cleaned up, get some food into you then it’s a long night’s rest. Alright?”

“Yes.” Ritsuka was quiet for a moment then asked softly, “Stay with me?”

“Of course, Master. I couldn’t imagine being anywhere else than right here with ya.” Robin flicked on the bathroom light. He smiled down at him, leaning down to press a soft kiss to his lips, “Don’t think I could let ya go anyway. I told you, I’m starved here so I’m gonna take everything I can get before Alter captures ya again. Make sure to spoil me a little, yeah?”

“Yes!” Ritsuka replied happily.
