The Eldest Succubus Breaks
The fifth of the seven succubus sisters, Bibi, slowly regained consciousness.
'Ugh... Huh...? What the hell is going on...?'
Bibi tried to turn her head and look around, but her body refused to obey her commands. It wasn't bound by ropes or chains, yet for some reason, it was frozen solid like stone. Wondering if some magic was suppressing her, she mustered as much mana as she could.
'Wha...? Why is all my mana...'
More shocking than her immobility was the fact that her body was completely drained of mana. Even as the fifth sister among the succubi, she'd lived two or three hundred years. She'd tangled with humans and seen it all, but never once had she experienced her mana being sucked dry like this. It was far more horrifying than she'd ever imagined.
To a demon, mana was life itself. It recovered naturally in tiny amounts, but that was negligible. She had no idea how many men she'd have to drain just to get back to normal. Without it, she was as weak as a regular human—even a fight against an ordinary guy was no sure win.
Only then did fear begin to creep into Bibi's heart.
'What the hell happened? I have no idea!'
She desperately tried to recall. She couldn't even pinpoint when she'd lost consciousness. Her last memory was heading to the Demon King's Castle on the Demon King's orders. There was a human called the Anti-Hero, and she'd been commanded to assist Jerome in awakening him as an incubus.
'Shasha messed up her Sleep spell, so I tried to step in. But for some reason, my magic didn't work either... And then...'
Nothing after that. No sight of her sisters or that Anti-Hero. Well, she couldn't see even if she wanted to—turning her head was impossible. She could only stare at the wall ahead, her mind racing with questions.
Bibi was braced against the wall with both hands, bent at the waist, ass thrust out behind her. Not by choice, of course—she'd woken up like that, locked in place. It was the kind of pose that evoked standing doggy with a man. Bibi preferred pinning guys down and riding them; this was unfamiliar territory.
She had a bit of a sadistic streak. Given the position, she half-expected that guy to mount her from behind any second. As a succubus, it wasn't scary per se... but something felt off, a nagging unease she couldn't shake.
That's when it happened.
Smack! Smack!
"Ahhn! Haaahn...! I'm sorry...! Minwoo-nim...! I... failed to discipline my sisters...! Hnggh...!"
From behind her came the sound of flesh slapping flesh, followed by a woman's scream. It was unmistakably the moan of a bitch drowned in pleasure—anyone could tell.
Bibi instantly recognized the voice: Riri, the eldest of the seven succubus sisters, their big sis. But she couldn't believe it. The Riri she knew never unraveled like that during sex.
Bibi knew Riri's style well. The eldest loved devouring fresh-faced boys just awakening to lust. The thrill of stealing their first time was irresistible, she'd say. So she always took the lead, seducing ignorant lads with her ripe body and soft techniques, playing the mature big sis or even mom.
Yet now, that Riri was flailing helplessly against a human man, panting like a beast in heat. Bibi couldn't see, but the sounds alone made it clear: she was getting dominated.
Bibi recalled Jerome the Incubus Lord's instructions. He'd said the goal was awakening this guy as an incubus, but no need to submit on purpose. If he lacked the talent, he couldn't become one anyway—no succubus could force it. Without aptitude, he'd just get drained dry by them and end up a vegetable. With seven of them, it was a numbers game. Bibi had inwardly mocked him, figuring one submission would be lucky.
But reality was veering off script.
The man's voice rang out.
"Good. Looks like you've finally learned some manners. Make sure to tell your rude little sisters too. Only the Demon King gets to talk down to me."
"Haaah...! Y-Yes...! I'll keep it in mind...!"
"Alright, then. Gotta pamper your sisters one by one now... Time to pull out? You remember the lines I taught you, right?"
As he spoke, Minwoo slapped Riri's ass hard with his palm. Her back arched like a bow, body convulsing.
"Haaaahn!! P-Please...! This lowly lesser demon, Riri...! Haaahn...! Bestow your noble seed upon me, Minwoo-nim...!"
"Yeah...! Etch it deep in that body! My cum isn't for just anyone...!"
Smack! Smack! Smack!
Declaring his release, Minwoo's hips pistoned even fiercer. Bibi, just coming to, didn't know it, but he'd already wrung hundreds of orgasms from Riri over the past hour. The same suggestion he'd used on Ernate and Siola—climaxing with every thrust—was working overtime.
Even after centuries, true orgasms with men were rare for Riri. Guys always tapped out first, before she was satisfied. Sure, mana replenishment was fine, but she'd developed sexual numbness without realizing. Maybe that's why she fixated on boys—mental satisfaction over physical.
Now, Minwoo was forcing a new world on her. Some trick made her body hypersensitive to his touch, moans spilling naturally. She'd feigned respect while inwardly scorning the "pathetic human." But somewhere along the line, she'd come to without warning from a single gesture or thrust.
Unlike with Ernate or Siola, Minwoo had no mercy for succubi. No holding back—he pounded relentlessly, driving Riri to the brink of mental collapse with endless peaks.
She hadn't lasted even an hour before submitting. One more might break her mind for real; primal fear gripped her.
"Cumming...! Take it deep in your womb!"
"Haaaaaaaahn...!"
As Minwoo thrust deep, his cock erupted, flooding her womb. His tip sealed against her cervix, not a drop wasted.
"Hahk...! Haaah...! Th-Thank you...!"
Uttering thanks she'd never dreamed of, Riri blacked out again. This time from sheer pleasure overload, not mana drain. In fact, his cum was probably refilling her.
"Tch, what a letdown... A succubus passing out in under an hour? No stamina."
Minwoo sneered, nudging the limp Riri on the bed with his foot. No response. He clicked his tongue.
Dealing with Riri, Minwoo had pieced together Jerome's intent in sending seven succubi and the magic circle on the floor. The circle was purely for him: temporarily converting stamina to mana like an incubus.
Minwoo had no mana himself, but the glow stick stored plenty. It seemed independent, but was linked to his body and circuits—like how the Demon King used her core. He could wield the absorbed mana through himself.
Jerome didn't know about the hypnosis, though. Even with the circle, he figured seven succubi would be tough. Subduing one was enough for incubus awakening—hence the swarm tactic. Bonus: fresh seed for them too.
But Minwoo had already crushed them all under "etiquette training," sampling one by one. He'd just fully broken the eldest, Riri.
"Now, which bitch next?"
"...!"
His mutter made the remaining six succubi flinch. Like Bibi, they were posed humiliatingly: hands on walls, asses out in a row. A spectacular sight even to Minwoo.
Overflowing stamina from the circle meant no refractory period. Plus, dominating one was slowly demonizing his body—unbeknownst to him.
"Oh yeah, there was that cheeky one strutting in front of me earlier... This one, right?"
Moments later, his hand touched her ass. Terrified, Bibi lost control and wet herself.
