Despite the intense gaze of desperate need directed at me earlier, Grayfia was, as she always was, the cool, controlled, voluptuous beauty of a maid. She excused herself after greeting them and went to check on the work done by the various maids of the estate during her absence. They would likely be chastised for their 'poor' work over the last few days, even if, in his opinion, they did a good job. Grayfia's standards were rather high, after all.
As she left the room, she gave me one last look. Intense desire burned just beneath her gaze; it was almost palpable, but it was unknown to everyone but me. I shuffled around a bit to hide my growing erection at that look. Her eyes shot downward, and it looked like she struggled not to lick her lips, her control wavering for but a moment.
Then she left, and I joined in greeting Rias' parents. After that, the kids and I played around a bit, as usual… but I was on edge the rest of the day.
… and rather horny. Kind of hard not to be when Satan's hot maid wife was visibly lusting after me.
But nothing happened throughout the day. She was as dutiful as always whenever we bumped into each other… even if her gaze lingered on my crotch more and more.
Even when Grayfia called me to the classroom to check on my progress in education nothing happened. She was more serious then… but that intense lust still radiated off of her and was directed at me.
I, of course, passed her little test with flying colors. I honestly would be embarrassed if I failed, given it was made for children. After the test, I may have expected the usual handjob or more, given her palpable lust towards me… but Grayfia shooed me off.
However, as I was about to leave the room, she leaned down and whispered into my ear, "Come back here this evening when your master is put to bed."
I struggled to hide the tent in my pants after that and waited for night to fall… well, what passed for the night in the Underworld, at least. Dinner was delightful as Grayfia cooked for them… and he noticed a theme. It was seafood with plenty of oysters, soft-shelled turtle soup, and a number of other foods I'd never seen before and assumed were Underworld delicacies. But I only assumed they were well-known aphrodisiac foods. Venelana gave saucy looks to Rias' father at the table, and I just ignored that while I feasted. I knew what was to come, so I may as well prepare!
After dinner, I felt the effects of the food strongly as my balls felt like bursting with how much jizz they were producing, and my dick was aching hard and leaking copious precum the rest of the evening. It was difficult to hide, so I told Rias I felt like taking a nap after a big meal. She looked understanding and kept to herself.
Night eventually fell, and I slipped out of Rias' room and back into my classroom. There, Grayfia was waiting for me… on her hands and knees, prostrating.
A certain urge to dominate welled up within me, and it only increased further with Grayfia's words.
"I greet my true Master. This lowly maid submits herself to your tender mercies, whatever they may be~."
My erection nearly ripped through my pajama pants. I quickly ripped off my clothes and stomped my way towards the kneeling maid. My instincts roared to take the maid and rape her full of my children over and over again. I restrained those feelings… for now.
My erection loomed over her, and steady drips of precum landed in front of her prostrated head, staining the carpet. I heard sharp inhales, and Grayfia's body shuddered with each sniff of my pre-nut. Her barely constrained figure jiggled pleasingly with each shudder, and I licked my lips and decided to tease her a bit.
I languidly jerked my cock and milked out dollop after heavy dollop of goblin pre cum. Each drop landed in the growing puddle with a soft *Drip*. The maid shuddered at the smell of goblin pre cum invading her nostrils, and soon I smelled the scent of a bitch in heat.
It was time to start.
I was tempted to speak… but decided against it. I was a goblin, and I'll do as goblins do. I crouched low and roughly grabbed her bangs and yanked her face up. Her face flushed intently at the action. With my free hand, I gripped the steel bar I called a penis and slapped her across the face. My fat purple bellend collided with a wet slap, leaving a stay pube and a wet smear of pre cum on the soft cheek.
I did it again and again.
*Slap!*
*Slap!*
*Slap!*
I slapped and shoved my dick against her face leaving faint imprints of the massive organ on her delicate features. Her arousal couldn't be more apparent as she said, "Thank you for your discipline, Master. I've neglected you for far too long."
I let out a sharp inhale as my own arousal grew at her words. I felt my control slip… and I let it.
With a rough brutish voice, I grunted, "Suck."
The maid obeyed without hesitation. Her hot breath tickled my pulsing glans for a moment before they were engulfed in her hot and slick mouth. Her head bopped in a steady rhythm as she took more and more of my bumpy goblin dick into her mouth. Her tongue swirled around my brutish glans with masterful twirls that sent shocks of pleasure up my spine. All the while, her eyes were gazing into my own, they were full of devotion and lust.
I breathed deeply with lust pulsing in my veins. I needed more. My hands roughly gripped her braids, and I pulled. In an instant, my brutish goblin dick was buried in her throat, and I let out an animalistic groan of pleasure, "Grahah~!"
Her eyes widened for a moment before molten lust filled them as she gagged on my sudden intrusion down her windpipe. I used her braids as handlebars as I began to pump my hips and fuck her pretty face. Drool spilled from her lips as I humped her face wildly. My heavy balls tensed, and I tightened my grip on her braids then, with a mighty yank, I forced my dick completely down her throat and unloaded fat, chunky ropes of goblin cum straight into her stomach.
Her eyes nearly rolled into the back of her head as my heavy testes pulsed and pulsed as they dumped their contents into the Devil's belly. I released my hold on her braids and slid my still-ejaculating dick out of her mouth, and I proceeded to shoot several yellowish ropes of nasty goblin cum all over her face.
Her gloved hands went to her face, and I noticed they weren't the pristine gloves she normally wore but ones spotted with off-white and yellowish stains. Were those gloves one of the ones I nutted on before?
A gloved finger scooped up a thick rope of cum, and she inspected it with a rapturous expression, "Ah~ How I've missed the smell and feel of your wonderfully thick and nasty loads, my Master~!" She purred as she sucked her cum stained gloves.
She moaned in ecstasy as she shoveled any stray ropes of fatty goblin jizz into her mouth. With each chew of my thick nut, she shuddered with pure bliss.
I had to admit, it was a very arousing sight, and I felt my balls churning up an even thicker load in anticipation.
Soon, the lewd maid finished scooping up his belated load, and her eyes looked lustfully at my throbbing erection.
"Let me care for your aching rod, my Master." Her cum-stained gloves wrapped around my dick, and she began to pump her hands.
Her slick gloves jerked my dick forcefully and quickly. Her eyes looked at me eagerly, and I grunted as I felt my balls tense once more. I let out a low groan as I blasted hot ropes of cum all over her face and uniform. Even as I was cumming she didn't stop jerking my dick. The maid was doing her level best to wring out my jizz!
Despite cumming two times in a row, I was still ready for more. It would take more than that to stop a horny goblin!
Once more, I enjoyed the show of Grayfia gathering my load and swallowing it down. The Devil clearly was in ecstasy as she gobbled up my nasty jizz. Her hands sunk into her breasts as she squeezed and groped herself in pure euphoria. Her arousal was so great her fat nipples were visible through the now cum stained fabric. She pinched and squeezed them as if wanting them to spurt milk.
I could help with that!
I lunged and pushed the woman down. I began to rip her uniform apart to get access to her massive tits! Once the pale mammaries were released, I wasted no time in roughly grabbing them and biting down on her thick nipples. I felt my energy invade the fat breasts, and a moment later, thick streams of milk sprayed from them!
Grayfia let out a low moan, "Mhn~ Drink as much as you wish, my Master!"
She didn't need to tell me twice! I roughly groped and sucked her tits with a feral ferocity. The smell of her arousal grew thick in the air as I abused her tits. As I drained her milk tanks, I felt my balls grow heavier and heavier as I instinctually converted the pilfered energy into semen. All the while, I pumped my dick in between the soft slick valley of her breasts.
After drinking my fill, I released her nipples and stood with an absolutely aching vein-riddled erection and heavy, sagging balls. I could feel more and more of my reasoning leave by the second as my churning balls demanded I dump my load.
It was then that Grayfia spread her legs wide and gave me an excellent view of her steamy and gushing cunt, "My dear Master, this needy maid will accept your thick, smelly, potent, and virile seed in this place today~" Her expression grew more and more desperate, "I want you to use me utterly. I beg of you, Master~ use this whorish maid and breed her like an animal~!"
The last of my rationality evaporated, and I let my goblin instincts run wild.
I lept at the spread legs like a feral beast and roughly thrust with wild abandon as I attempted to shove my aching dick into her hot cunt.
"Ah~ here, let me lead you, my Master, ~" Grayfia gently grasped my dick and angled it till the head was just about to slip into her.
The second I felt her hot depths, I slammed my hips into hers. Grayfia's face instantly scrunched up in pleasure, and she moaned, "Ooh! N-not that… Sudden!"
Strength filled my limbs as I lifted her hips up and began to slam myself in and out of her sopping wet folds. With every thrust, I dug deeper into her tight cunt! My heavy balls impacted with loud *Plaps!* at every ferocious thrust.
*Plap!*
*Plap!*
*Plap!*
Echoed loudly in the room as I fucked the maid fast and hard. Her fat tits bounced with every thrust and were an amazing sight. But the most lust-inducing had to be the expression on the maid's face.
It was pure and utter bliss, plain and simple. To see such a face on the normally calm and collected Grayfia was euphoric.
I grunted and groaned like an animal as I pounded into her.
"Y-yes t-this is what I've always wanted~!!" She moaned loudly and freely as she pinched her fat milk leaking nipples.
"Use me more! More, more, more! Treat me like a fuck toy, my Master!!" As she screamed in bliss, I felt her walls tighten and coil around my bumpy wart-covered dick. I wrenched her cunt open despite its attempts to squeeze me in a vice grip, and that simply caused the woman to climax yet again as I pummeled her pussy into compliance.
I squeezed her legs together, and the tightness of her cunt increased further. I groaned as I began to fuck her even more intensely. Her Devil pussy gushed around my invading length over and over, and soon I felt my own peak near. My dick surged in size as my climax was seconds away, and Grayfia shuddered once more and loudly screamed, "Cum inside me, Gobu!! Breed me!!!"
At those words, I couldn't hold back anymore. My body glowed, and I grew in size as a Goblin King took his first conquest.
Grayfia's eyes widened in surprise for just a moment before they rolled into the back of her head as my body wasn't the only thing that grew but my dick as well. My sizable cock nearly doubled in length and girth in an instant spreading her cunt wide and spearing into her deepest spot. Her belly bulged from the sheer size of my dick battering her cunt.
"Oooh- Ooogh~!!!" She screamed as I stretched her more than she'd ever been before.
"Breed!! Slut!! Mine!!!" I growled as the brutish head of my dick battered down the entrance to her womb with no contest, and then I felt my titanic sloshing balls clench tight as I unloaded a monstrously thick torrent of nasty clumped-up goblin jizz into the womb of the Devil whore! Her cunt spasmed and squirted as her biggest orgasm yet rocked her body. The walls of her pussy writhed as they did their best to milk their master's rod with every last drop of potent jizz!
*SPLURRT! SPLORRT! SPLRT~!*
With each massive throb, thick ropes of greasy goblin jizz blasted out of my dick and into Grayfia's swelling womb.
"NGHH~" Grayfia moaned as she regained her bearings… slightly. Her body still spasmed around his fat cock.
Even as my orgasm began to subside, I was still horny. I had lots of pent-up breeding desire and I would not be stopping now!!
"Grah!" I grunted as I began to fuck her once more.
"Oooh~ M-mess me up more, my Master!!" Moaned his breeding slut as he began to pump his hips faster and faster.
He obliged her over and over again. Hours passed as he rutted her and filled her womb with potent, virile goblin jizz.
____________________________________________________________________________________________________
Small fingers pumped into hairless, puffy sex at a forceful, steady pace. Feminine juices gushed from the small swollen pussy, staining the sheets below a small childish frame. Rias Gremory panted with glazed eyes as she moaned into her pillow as she shared the sensation of Gobu rutting Grayfia completely and utterly for the past few hours. Her hips bucked nearly in time with Gobu's as his fat green wart-covered dick plunged Grayfia Nee-chan's hot, wet, and oh-so-tight pussy~
Rias groaned as she felt her sister-in-law's walls tightly grip her phantom penis snuggly. She then moaned into her pillow as she felt her phantom balls tense and dump their load straight into Grayfia's already overstuffed womb.
"T-this i-is the best~!" She moaned as she continued her voyeurism.
__________________________________________________________________________________________________
Grayfia let out a garbled moan as she lay covered and filled with what had to be gallons of thick nasty goblin semen.
…She had finally given in to her sick desires.
And it was everything she had ever wanted.
Gobu had truly and viciously used her. He pried open her servile cunt with his nasty, fat, wart-studded goblin dick and blasted her needy womb with gallons of his thick clumpy yellow goblin semen. She still shuddered at the feeling of those fat warts stirring up the walls of her pussy in ways she never thought possible. The goblin had shown her a new realm of pleasure.
And all it took was acknowledging him as her true Master and betraying Lord Lucifer.
The thought of her betrayal sent hot, sick pleasure through her worn-out form.
She was a twisted, sinful woman… but she was a Devil in the end.
Grayfia rubbed her cum stuffed belly with a blissful expression. Sirzechs may have impregnated her… but it was Gobu who bred her.
She had a sick hope that perhaps some of his potent wrigglers would somehow do the impossible and impregnate her again.
Even if they didn't, she would bear her Master's children one day no matter what. She was his in all ways now, so it was her duty to do so.
__________________________________________________________________________________________________
The rutting pair were unaware of what was taking place within Grayfia's womb. Gobu's goblin semen assaulted the fertilized egg within Grayfia's womb relentlessly. Even if the egg was fertilized, the potent goblin sperm tried to impregnate it anyway.
Normally, the difference in power between Gobu and the infertility of female Devils such as Grayfia would make pregnancy an extremely rare event despite the prodigious virility of goblins.
But there was already an egg waiting for them, and goblin semen was relentless. A Goblin King's sperm will not be denied its first conquest! Trillions upon trillions of potent goblin swimmers were continuously pumped into the Devil's womb, and they battered against the egg… until one slipped through.
The sperm did its best to overwhelm the DNA of the other male… but it lacked the power to do so… completely, at least. The goblin sperm weaved its way into the developing fetus' DNA, and the resulting child will have goblin blood no matter what.
