Could It Be the Goddess?
Squeeeak.
A strange black light flickered from Morus's right hand. He brought it to his cock, and from there it spread across his entire body before turning transparent.
"What's that?"
Serena's curiosity was piqued by this bizarre trick that lay completely outside her knowledge.
"You don't know? It's contraception magic—Demon King's Army version. Coating the whole body in demonic energy to block pregnancy, and more importantly, a vital means to safely fuck an STD-ridden slut like you who's armed to the teeth with holy power."
Morus shrugged, flaunting his knowledge while simultaneously provoking Serena.
"You fucking bastard!!!"
"...You managed to swear through the magic."
Telling someone they have an STD is an insult that lands hard regardless of gender. And when the target has just been face-fucked, it hits even harder. That provocation made Serena slip and let the word "holy power" escape.
"You fucking—I've never even fucked once in my life, so how the hell would I have an STD, you piece of—!"
"The goddess face-fucked you, didn't she?"
"Ah. Right."
Morus's correction made Serena flinch. She was no longer a virgin. In this eroge world, a non-virgin heroine had fewer rights than a beast.
And while she was chewing on that misery, something suddenly flashed through her mind. She looked straight at Morus.
"Moru—"
Zing.
"Guh! Master."
She had tried to call his name, but the magic around her throat twisted it into "Master" instead. Serena decided to ignore that for now and pressed on.
"You're saying I have an STD?"
"Yeah, well… strictly speaking it's not a disease, just the mutual rejection between holy power and demonic energy. But right now you've got holy power and I've got demonic energy, so from each other's perspective, yeah—it's an STD."
"So it's a magical STD, then?"
"That… would be right?"
Morus could feel the conversation starting to drift into weird territory, but old academic habits made him keep listening.
"But STDs usually come from screwing around or catching them from someone else, right?"
"True."
"I've never stuck anything weird into my own pussy. And… even if it was face-fucking, the only one I've ever done it with is the goddess."
Serena struggled a little over the face-fucking part, but she kept going.
"Uh… uhhh!?"
As he listened, Morus's eyes went wide. If the sex slave's logic held, then the conclusion of that story was—
"Then that means the goddess is the one with the STD, doesn't it!?"
Thud.
At Serena's conclusion, the goblin dropped the jerky it had been greedily chewing and stared at her with the expression of someone who had just witnessed the most shocking thing in the world. Morus wore the exact same face.
SYSTEM ERROR!
SYSTEM ERROR!
The system that had been monitoring Serena's voice also glitched out at the sound of common sense being flipped upside down.
"Well? Am I right or am I—"
Thuuunk!
"Oofuuuuk!"
Serena was crowing in triumph at having reached her answer when something scorching and pillar-thick invaded her cunt, ripping a scream out of her.
"You fucking bitch! My cock's about to die!!! Squeeze that pussy and get it hard again!"
"Kikit… Even monsters don't come up with shit like that. Female, crazy."
Thud! Thud! Thud!
The cultist pumped in pure rage while the monster shook its head like it had completely lost its appetite.
"I'm sooorryy I'm sooorryy! I won't talk back again so please pull it out!!!"
And the holy maiden—no, the holy sex slave—who had just committed an unprecedented blasphemy convulsed as her nervous system short-circuited under the twin assault of the aphrodisiac exploding her brain cells with agony and ecstasy.
It hurts! It feels good! It hurts it hurts it huuurts… wait?
Serena's brain registered the hyper-sensitized nerves as pure pain. But pain is a fatal weakness for any living thing, and the brain has a solution for that.
"Ooooh♡"
Convert the pain into pleasure. And Serena had more than just a brain—she had a cunt.
Possibility of Mental Collapse: 69.74%
As you can see, the cunt was working overtime to protect its user's personality.
Pain-to-Pleasure Conversion: 100%
And it even threw in free service.
Squish♡ Squish♡ Squish♡
With her brain and cunt working in tandem, love juices soon began flooding out of Serena's pussy like a dam had burst. Look closer and there was a little yellow mixed in, but the important part was that all of it served as lubricant, reducing friction between cock and cunt. The smoother pumping only drove Morus's pleasure higher.
"Nngh! You fucking bitch… Your pussy clamps down just as hard as your blasphemy."
Morus was genuinely stunned. Are all women's cunts this tight? he had wondered—but right here, right now, he could swear on the goddess and on corruption itself.
This cunt-bitch's grip was top-tier, beyond anything that could be compared. His male instincts, and even the cock dulled by contraception magic, were screaming it.
Whoosh.
Morus flung off his robe to cool the heat in his body even a little, stripping naked in an instant.
Watching the two bare humans, the goblin felt like it was observing a pig mating with a person.
"Hey. Open your mouth."
"Eheh… mmph."
Slurp, suuuck.
Morus claimed the half-conscious Serena's lips.
Feels so gooood♡ Moreee.
Serena couldn't even process that a man was kissing her; she simply drank in the pleasure the kiss delivered.
Bounce~ Bounce~
Psssh!
As if the excess pleasure couldn't fit inside her body's vessel, Serena's massive breasts heaved violently and sprayed milk.
"Kigit, human! Tits! Give me!"
Seeing Serena spray milk, the goblin went berserk, pointing at her chest and hopping up and down.
"…We have a contract, remember? First round is mine. You can go after."
Morus shoved the contract in its face and refused. The goblin felt the magic circle around its neck start to tighten uncomfortably.
"Kieeeeeek!!! Pussy! Me too pussy!"
"Uhooooh! More, give me more!!!"
And now even Serena, high on drugs and pleasure, was wailing along, making Morus think this was a complete fucking circus.
"And yet somehow I'm still about to cum."
Thinking she was an incredible woman in every possible sense, Morus finally unleashed the load he had been holding at the absolute limit.
Blurt! Blurt!
It erupted with the vigorous force of a virgin's first ejaculation tasting pussy for the first time, but unfortunately the contraception magic blocked it from reaching Serena's womb.
After finishing, Morus pulled his cock free of Serena's pussy. As if reluctant to let him go, her love juices clung to his shaft in long sticky strands.
"Hooo… Not going down at all."
Morus marveled at the situation: under normal circumstances his cock should have wilted, yet it remained painfully erect.
He glanced at Serena, who lay face-down twitching like a dead frog, then unlocked the shackles binding her.
Clack.
"…"
"Tsk."
Even free of the shackles she gave no reaction, so he clicked his tongue, lifted his foot, and put his weight into a kick aimed at her side.
Thud!
"Eheeiiik!!"
Letting out a scream so vulgar even a beast wouldn't make it, Serena snapped back to consciousness. She writhed a few times, then after a moment managed to pull herself together and look around.
"Auuu…"
"Slave. Clean it. With your mouth."
Morus dangled his cum-caked cock in front of her. Serena, briefly back in her right mind, found it so repulsive she averted her eyes.
"Want another shot? And if you bite, you die."
Twitch.
At the word "shot," Serena's body jerked. To preserve her life she abandoned every shred of dignity as a man, trembling as she tried to take the cock into her mouth—only for the foul stench to freeze her with her lips open, unable to descend.
Grab.
Suddenly a massive hand clamped onto the back of Serena's head. Realizing what came next, she frantically tried to pull away, but—
"Wai— mmph!"
Morus's hand mercilessly forced her head down. Serena was made to take the cock into her mouth and endured the urge to vomit from the smell at the absolute limit of her willpower.
Slurrrp! Chuuuup♡
Before long Morus had both hands tangled in Serena's hair, pumping her head up and down.
It was a zero-technique, zero-tongue-work blowjob, but Serena's warm, spit-filled mouth was more than adequate for the job of cleaning.
"Bleeeeh♡"
The cock that pulled free of Serena's mouth gleamed with nothing but her spit, catching the torchlight.
"Well then. Time for round two?"
And so the screams and complaints echoing through the cave did not stop for quite some time.
