Summary: Continuation of my 'No use crying over a few laid eggs'. The moment he walks into the kitchen to find his Father had already made his coffee, Shouto knew he was in trouble. When he tries to bolt, Enji catches him and states that he can't wait any longer. He needs an incubator now and Shouto is the perfect warm body.

It became immediately obvious that something was wrong the moment he walked downstairs in the morning. Enji was sitting at the kitchen table, staring blankly down into a cup of coffee. Shouto stopped dead in the doorway, his brows knit together. Despite being capable of it, Enji never made his own coffee or his own breakfast. He always made Shouto do it. There was no food to be seen but the coffee was indication enough that something was off. Distantly, Shouto could hear the incubator moaning loudly from the nursery. It’d been a hell of a shock when Enji came home from a scavenge with this new one in tow. He never brought them home – he found them out in the mass expanse of the forest, fucked them, laid his eggs and collected the gold, leaving the once incubators broken and constantly itching for the pleasure of being stuffed full of eggs. Even bigger shock was Enji personally impregnating this new one – he usually used the semen generated by the monster living in his belly. Course, after he monitored the incubation a couple of times, he understood why Enji was so taken with him. He was very cute and the quality of the eggs he produced was far better than any other incubator Enji had found. It only made sense that Enji would want to keep him. Still, seeing someone who used to be a rational person being slowly reduced to a dribbling mess, constantly begging to be stuffed full of eggs, never ceased to make him nauseous. 

“Morning.” Enji said, his voice a low rasp. Something about the distant, distracted he said that one word made his hair stand up on end. Dryness plagued his throat. The rate of his heartbeat picked up drastically. Years of living with this asshole had given him a pretty good indication when it was time to turn tail and run. Right now…the last place he needed to be was right there. 

Taking a careful step back, Shouto responded in a guarded tone, “Good morning. I’ll go check on the eggs. Excuse me.”

Turning sharply on his heel, Shouto made to speed walk his way out of this potential trouble but before he could take a single step, something warm and wet wrapped around his waist. His heart dropped like a stone down into his stomach. A ball of breath lodged in his throat, leaving his lungs empty and burning. No…no, no, that…that wasn’t what he thought it was. Shouto very slowly looked down. A flush of cold raced across the surface of his skin. His heart dramatically skidded to a halt before jumping back to an erratic, off-beat rhythm. It was what he thought it was. One of Enji’s dull pink tentacles was wrapped snugly around his waist. The fluid that coated the muscular mass was already starting to eat through his clothes. Swallowing with considerable difficulty, Shouto jerkily looked over his shoulder at Enji. Scratching idly at the large scar that dominated the side of his face, Enji’s dark gaze flickered over to settle on him. 

“The little one still hasn’t given birth.” Enji said flatly. 

“It’s going to take a few more days. I told you that when you decided to go for highest quality.” Shouto replied, struggling to keep his voice even. 

Enji stared at him silently for a moment before saying something that caused every muscle in Shouto’s body to tighten up, “It will not wait a few more days.”

“Then go find someone.” Shouto said, his lips numb. Run…he needed to run, now. Shakily taking a step away, flinching when the tentacle tightened, he pushed out through clenched teeth, “There should be-“

“There is no time.” Enji said, slowly getting to his feet, large hands braced on the table. Those dark eyes bore into Shouto. His stomach lurched sickeningly. Straightening to his full height, towering over Shouto, the corners of Enji’s lips quirked up in a slight smile. Dozens more of those huge, pink tentacles sprang out of his back, filling up the small kitchen. A spasm of enraged fear howled through him. No…no, this fucker couldn’t possibly be planning on using him?! He…he was his son! Shouto took another step back. The tentacle tightened even further, powerfully squeezing his waist. Holding out a hand, Enji offered a small smile, “This was inevitable, Shouto so don’t struggle. Come here, let me bless you with this pleasure.”

“No. Stay away from me. Don’t touch me!” Shouto snarled, straining against the tentacle. 

Sighing, Enji dropped his hand, the smile fading from his face. Several more of the tentacles sprang forward, wrapping around his legs, arms and torso. Crying out sharply, rage and terror thrumming in his head, Shouto thrashed about, desperate to get free. This fucker couldn’t be serious! He wasn’t a fucking incubator! He wouldn’t let him put those disgusting eggs inside of him! The tentacles easily lifted him up off the floor. Endeavor walked out of the kitchen, heading towards the nursery. The tentacles followed, carrying Shouto behind him. The fluid coating the thick muscles quickly got to work. By the time they reached the nursery, he was naked, his clothes reduced to tatters of fabric that dotted the floor. Panting rapidly, the fear pulsing in his belly grew even stronger at the sight of the incubator writhing on the bed, his belly swollen and round with eggs. He looked up at them hazily with a flushed, lewd expression on his round, freckled face. Whimpering, he held out a trembling hand to Enji, but he ignored him. 

Many of the tentacles slipped away until there were only three – one wrapped around each of his legs and the last curled tightly around his waist, easily holding him aloft. Turning, Enji looked up at him, a strange blaze of near deranged heat burning in those dark eyes. He recognized that look…it was the one he always got when the beast dwelling in his belly demanded for more eggs to be laid. Shouto swallowed hard, his heart a blur of terrified motion. The tentacles roughly yanked his legs open, exposing his crotch and ass. One of the larger tentacles wriggled forward to press its large, bulbous head to his twitching, virgin hole. A hard shudder wracked Shouto’s body. Disgust skittered across his skin, leaving him feeling shaky and squeamish. He couldn’t be serious! He couldn’t mean to actually incubate him! 

Eyes stretched open wide, horror stampeding through his veins, his breath coming quick and erratic, he ground out, “Don’t! Don’t you fucking-“

“Be still.” Enji murmured, placing one of his large hands flat against Shouto’s belly, “You are meant for this. You are meant to join him…to be part of my duo of perfect incubators. No longer will I have to settle for the random fools who stumble across my path. You both will service me well.”

“Fuck you!” Shouto howled, his blunt nails scraping along the smooth surface of the tentacle wrapped around his waist. Not this! He didn’t want to become this fucker’s incubator! He didn’t want to end up like the other one! But no matter how hard he struggled; the tentacles’ hold was unbreakable. If…if he couldn’t break free then he would just have to stay strong while this fucker had his way with him and make a break for it at the earliest opportunity. The tentacle around his waist slid up further, quickly coiling around his stomach, chest and neck – not stopping until the tip was at his mouth, playfully rubbing that despicable liquid against his lips. It curled tight, restricting around his throat, making it difficult to breathe. His body burned with feverish heat. He felt like he might vomit at any moment. Stepping closer, those dark eyes staring intently at his face, Enji leaned forward to press a kiss to his belly. Shuddering, bile bubbling up into his throat, Shouto opened his mouth to deliver another demand that Enji stop this but the tentacle around him abruptly jerked him down just as the tentacle pressed to his hole slammed up, impaling him on its massive length. 

Eyes bulging, mouth twisted in a pronounced, agonized grimace, Shouto tried but failed to hold back a strangled howl. The tentacle wrapped around him curled even tighter, further restricting his airway as it dragged him further down, forcing more and more of the tentacle into his spasming ass. Sharp, burning pain radiated up his spine as he was stretched to his break point. His stomach wailed in protest. Every organ in his body was being jostled about, given no other option than to accommodate the massive intrusion. Full-! He was stuffed so full! His ass…his ass was going to break! Mouth hanging open, struggling to breathe around the agony of being penetrated by something so huge, Shouto was given no time to adjust. Once the tentacle was sunk in so deep, his stomach was bulging out from it’s sheer mass, the other tentacle wrapped around him began to rapidly bounce him on the thick girth, quickly pulling him up then dragging him back down, fucking him violently on the pulsing, sticky length. Enji stood close, watching him being violated with an unblinking, hungry stare. Those eyes on him flamed the shame raging in his belly to burn even more sickly. Gritting his teeth, Shouto welcomed the pain, grateful that, for whatever reason, Enji was treating him differently than the others. The tentacles usually activated the mucus that covered them – creating an aphrodisiac effect that made this instantly pleasurable. 

This…this was good. He could deal with the pain, the shame, the discomfort – it was just something he needed to endure. If this kept up throughout the entire process, he would be alright. He just had to endure this then…he would finally be free of this bastard. No way in hell would he stick around here any longer, being forced to help with this sick process. He would-! Something big nudged against his already stuffed full hole. Shouto’s eyes widened even further. Another one?! He wanted to put in another one?! No…no, he couldn’t! If he did, he would be split in half! His hole couldn’t take anymore! A large, hot hand stroked over the side of his thigh, drawing his attention. Enji had stepped in even closer, the fire burning in his eyes blazing even more brightly. The tentacle wrapped around him abruptly jerked him down hard, forcing in even more of that immense length. A fresh wave of pain rolled through him but, to his horror, it was quickly followed by something else. Something hot and tingly. His cock twitched. Blood began to pour down into the limp organ, prompting it to harden. No…fuck, no! Shouto frantically scrambled to focus on the remnants of the pain of being so forcibly penetrated. It was that alone that could save him! 

“Open up wide, my beautiful little one.” Enji breathed, “Accept all of me.”

“No-!” Shouto gagged, weakly struggling in the tentacles hold. 

Letting out a slow, shuddering breath, Enji reached up to gently cup the sides of Shouto’s head. Dipping down, he pressed a soft kiss to his lips, slipping his tongue out to trace the seam of his mouth. A strange burst of heat erupted in the base of his belly. His steadily hardening cock throbbed. Curling his thick, broad fingers around Shouto’s jaw, holding his head in place, Enji peered into his eyes as the second tentacle shoved up, forcing itself inside alongside the other. A sharp bolt of scalding hot pain shot up his spine as the muscles in his ass were stretched far beyond their limits. His stomach gurgled dangerously. It bulged out even further, becoming almost grotesque in shape. Unable to make a sound, mouth stretched open in a silent scream, Shouto barely registered Enji shoving his tongue between his parted lips. Breaking-! He was breaking! The tentacles were going to kill him! He was going to die! His stomach…his stomach was going to rip! Yet…despite the pain, the certainty that these damn things were going to rip him apart, the shockwaves of heat were becoming steadily stronger. His cock was fully hard. Precum dribbled from the slit. The two tentacles inside of him moved congruently, thrusting in deep, stirring him up, messing him up. The pain…it was slowly being overshadowed by the pleasure. The more the tentacles moved inside him, the more Enji playfully teased his tongue, spreading an intense bitter flavor throughout his mouth, the bigger and bigger the flare of heat burned in the base of his tortured belly. He…he was starting to feel good-! These damned tentacles were starting to make him feel good-! 

“I shouldn’t have waited this long.” Enji murmured against his lips, one large hand sliding down to wrap snugly around Shouto’s length, wrenching a sharp cry from him as his hips weakly bucked forward to drive his throbbing, aching cock through the tight ring of Enji’s hot, calloused fingers. A ripple of pleasure rushed through him, pushing the pain even farther away, “You’re just as beautiful, just as perfect as him. I don’t know why I waited this long but…” Enji chuckled, straightening back up, dragging his tongue over his lips to gather up Shouto’s taste, “no time like the present to rectify a mistake. Come now, my little one – let me show you the depths of this pleasure.”

“No-.” Shouto gasped, “Don’t-!”

A harsh squeal wrenched itself free from his throat when a third tentacle rushed forward to add itself along with the other two. Gurgling, his eyes rolling back into his head, Shouto violently trembled in the tentacles hold as he bounced violently in their grip, fucked so hard, it felt like he was being turned inside out. There was pain, a lot of it but there was even more pleasure. Fuck…fuck, fuck, fuck! His mind was going completely blank. Every inch of him was buzzing with that ecstasy. His stomach, his ass, his body…everything was melting. He was stretched open so wide! He was stuffed so full! His stomach…the three huge tentacles were in his stomach! It felt like they were trying to push completely through him. It…it felt so fucking good! Enji jerked off his throbbing penis in time with the tentacles cruel, rough thrusts, ramping the pleasure up even further. Blood roared in his ears. It…it was getting harder to think straight. This…this was bad. This was really bad! If this kept up, he was going to break! He was going to end up just like the other incubator! He was going to spend the rest of his life having eggs laid in him! He…he didn’t want that-! He didn’t-! 

“Here it comes, my little one.” Enji whispered, brushing the backs of his fingers along the curve of Shouto’s sweaty cheek. “I know your eggs will be beautiful.”

All three of the tentacles slammed in deep. The tentacle wrapped around him yanked him down hard, forcing them in even further. A loud, harsh squeal spilled out of him as the three swelled up even bigger. No-! NO! He didn’t want the eggs! He didn’t want to be an incubator! He didn’t-! The first egg slipped free from the tip of one of the tentacles, landing heavy in his stomach. An immense, devastating wash of pleasure slammed into him, wiping away all the resistance remaining. He came with a humiliatingly high-pitched squeal. With that one came the flood. Dozens of large, smooth, eggs flooded into his belly, causing it to bulge bigger and bigger until the rounded curve was sagging. Tongue hanging out of his mouth, eyes heavy lidded and hazy, Shouto trembled in the tentacles hold. The last remnants of reason struggled to hold firm but were steadily being crushed underneath the amazing ecstasy of those eggs being laid inside him. His stomach-! His stomach was going to burst but he wanted even more! He kept cumming as more and more eggs filled up his belly. The pleasure never stopped – it continued to dominated his nerves until it felt like he was being rewritten. In a way…he was. This was what the monster did…this was what it wanted…to have a willing slave who’d gladly take every egg it had to offer. 

The thought drifted across his foggy mind but produced no fear. Instead, what came from that realization was a mad squeal of glee. More…more, more, more! He wanted even more eggs! He wanted his Daddy to lay even more eggs inside of him! He wanted him to take that big, strong cock and impregnate his eggs! He wanted to lay his Daddy’s eggs! Seeming to sense his thoughts, the tentacles, now having finished laying their eggs, leaving his stomach grossly bulging, heavy and swollen, slipped free from his gaping ass. Shouto whined low in his throat, immediately viciously missing their mass but he didn’t have to mourn for long. The tentacle wrapped around him lowered him down and held him horizontally in front of Enji. Smiling widely, his dark eyes blazing with deranged lust, Enji ripped open the front of his trousers, allowing his massive length to bounce out. Shouto’s eyes widened with excitement. His breath caught. Inside-! He wanted it inside! He wanted to be impregnated by that cock! Clamping down onto Shouto’s hips, Enji lead the bulbous head to his sopping, gaping ass and slammed forward, easily sheathing the entirety of his length inside. 

Howling at the top of his lungs, a delirious smile stretched across his face, Shouto came once again. White splattered all over himself and the tentacle. Good-! Good-! It felt so fucking good-! Daddy’s cock felt so good-! More-! More-! Moaning loudly, Enji roughly thrust into him, pounding into his welcoming hole with enough force to send him jolting forward. His engorged stomach bounced with every impact of their bodies. Squealing, mewling and howling. Shouto shuddered when one of those thick tentacles wiggled into his mouth. A fresh bolt of pleasure raced down his spine, prompting another intense orgasm. Sucking hard on the length, rubbing his tongue against the spongy flesh, he distantly realized that Enji’s thrusts were becoming jagged, erratic. His eyes flew open wide. Cumming?! Was he cumming?! Was he going to cum inside him?! He wanted it! He wanted it so badly! Letting out a growling moan, Enji wrenched Shouto in close, smooshing the plush curves of his ass to his pubic bone. His massive cock swelled up even bigger then, with a shudder and another moan, he came, flooding his insides with a thick flood of scalding hot seed. Screaming around the cock in his mouth, his back arching, jizz pouring out of his cock as he came again. That incredible warmth flowed into his belly, drenching the eggs, which became to grow even bigger as the beautiful seed penetrated them. 

A large, hot hand smoothed over his engorged belly. Letting out a raspy chuckle, Enji murmured, “See? Isn’t this so much better than struggling against me? This is what you are meant for, my little one. Now, you and your new brother will always know this pleasure. You will always be my perfect incubators.”

Enji’s cock slipped free from his sloppy hole. The tentacle in his mouth lovingly rubbed against his throat before sliding out as well. Shouto was carefully laid down onto the bed next to his new brother. Panting heavily, his freckled face flushed, he snuggled close, pressing his forehead to Shouto’s. A large hand brushed through his hair before reaching over to fondly stroke his new brother’s cheek. Sighing happily, his stomach so pleasantly heavy and full, Shouto quickly began to doze off. Enji kissed the corner of his mouth, whispering, “Sleep, my little one. There will be much work to be done when you awake.”

“Yes…” Shouto mumbled, a weak spark of excitement igniting in his chest. From his side, his new brother giggled. A soft, warm palm brushed against his own as his new brother took his hand. Weaving their fingers together, Shouto made no attempt to fight off the exhaustion swamping him. He needed to be fully rested and ready for whatever Enji had planned for him next. After all, he was one of his perfect incubators. That was a lot of responsibility and he was determined to show Enji just how perfect he was.
