Once he's done with this bitch

Dexter looked at the filth covering her and spewing out of her twitching hole, as she tried keeping a nervous smile; deferring to a primal aura stronger than hers. He told her to lick it up, tugging her head to the puddle of his cum, and while otherwise being unable to be moved by him, she willingly followed along with his crude demands, crawling over and planting her face down in to gulp and sniff at his seed; her bestial urge to conquer telling her to take in this vitality and do all she could to take in more of his warrior spirit to strengthen hers.

*smack*

"I said 'lick it up', not sip, you whore" Dexter chided, following his new interest of seeing if he could make her ass any redder.

She moaned at his aura temporarily rising with his rage, and went to licking the ground with a demonically long tongue, while her thick limbs still twitched, propping her up on all fours.

The refractory rate of a Harem Master barely needed considering as he was back up immediately, but he still felt disgraced to have only this shamelessly uncivilized bitch to use.

He used her stiffly muscled thighs to give himself a thigh-job, but with her body as tensed and jittery as it was, it felt like jerking off between two rocks, and using her ass-cheeks felt too tightly flexed to use at the moment, her pussy was already far over filled from the last couple rounds.

Looking over his options, he concluded 'this demon-bitch doesn't even have a tail, so I'll give her one'.

The Oni then sharply gulped down the seed on her tongue, and felt his cock-head stretch her smallest yet tightest muscle. After a brief moment to wear down her rim, he slid into her ass, making her grit her teeth against her tongue and drool further down the puddle beneath her.

She bent her face down closer to the ground to proportionally raise her ass to him, gnarling out over his cum and rhythmically clenching her already tight asshole; still struggling to fit him pressing mercilessly deeper.

Pounding past her well muscled sphincter and into her intensely warm rectum, Dexter once again felt irritated by sensation of fucking a living statue that could only move on her own and in result of what he made her feel, but so overwhelmingly tough that he couldn't do much to move her with applied ****; the lucky exception being her relatively soft sexy bits that he could pry open with well directed ****.

He kept smacking her ass in vain; only seeing its red tone brighten as if blushing on contact, without adding any of the sadistically inspired pain he wanted. Dexter couldn't reach this titanic bitch's throat in this position and the same could be said about trying to grab her horns again, getting her hair was a solid maybe, but the chain attached to her new collar was suddenly within reach.

He tried yanking her up from the cum puddle, tugging on her chain and ordering her to look behind at him with her pleased smirk; to see him try pillaging another hole off the sheer might of his fuck-stick and aura.

"Fuck, boss keep trying with that ass!" she joked, while tightly clenching around him; causing him to briefly panic at the intense pressure, until he shuffled himself around inside her and used his other hand to pinch at her clit; disrupting some of the challenge she was intentional presenting.

Angered by even the playful act of challenging him, Berserk had more rage to act on and source his strength from, he forcefully pressed all the way in; smacking her thighs with his consistently heavy balls, his push echoing out to the back of her pussy, and bulging out near her gut to the point of the pressure leading to more seed to seep out of her womb.

"How about you use that ass to be a good-whore, and start backing it up bitch!" he commanded, now fucking into her deeply but still not a fan of her being a stationary fleshlight watching herself as open territory be taken despite all her tightness.

Logically, the Oni was already his after he dominated her pussy, yet he wanted more and to take her again just with higher stakes; having her thrust back to crush her more evenly and to be prostrated out her as his bitch. However, even a 'tamed' Oni posed plenty of danger, the hardness of her thighs and rear pounding against him, gut tensing against his bulge inside her; all showing it plainly, but that was just the reason he needed to keep going even harder; she recognized him as a superior pillager to follow for that sake, but her body had yet to fully see itself as the pillaged.

The meaty smacks off of his thighs and the hard thuds off of hers continued to clang, mixing together, heightened by her thicc ass shaking itself as she swung her the two beautifully sculpted boulders with fierce speed, tightly consuming his cock again and again. One *plap* would've been enough to knock a sane man over into reverse cowgirl to passively watch her ass crash down on him, but the passive insubordination of an admitted underling fueled Berserk to focus his grip on her; stretching the walls of her asshole, knocking the against the back of her pussy, and repeatedly flattening her womb as his cockhead bulged past through her gut; stamping down who this Oni's Master was.

"MMm-Boss!" she groaned, trying to meet his gaze despite her own becoming lost from rising pleasure as she gritted down even harder, barely grounding herself by focusing on the sound and weight of his heavy balls platting onto her soft wet cuntlips.

"Please cum in my ass! Attack my rear! It's your tight little fuck-hole trophy, free to the victor to fill again and again!"

"Fill it!!" she shrieked, as her hole clenched hard preventing escape as the pleasure spreading from it overtook her body, with the swell between her abs throbbing and pelting the walls of her colon hard with shots of cum thickly filling her bowels.

The sheer weight sagged against her otherwise toned stomach and the high pressure let him ease his way out; unplugging her densely packed ass and taking the opportunity to paint the back and cheeks of his red anal-fuck toy with the last of his load, to show her feral brain its place even if it's rendered dull enough for her to splash face first into a puddle of cum as she fell limp.

Dexter's dick rested between her still trembling cheeks as he panted out; still sourcing rage at the thought of the system insulting him with such a low-ranked summon.

Said system dinged again.

'10% increase in strength from summon interaction'

'New skill: Echoing **** (Knock-Back)'

Briefly testing his new skill he went one more round with her dazed; still not strong enough to move her body with a push, but after a few thrusts in this stiff but twitchy fleshlight, he felt her cheeks clap from his own strength building up and echoing inside of her; progressively growing to sway her whole body with the side of her head lightly thudding against the ground and creating ripples through his semen.

He felt some accomplishment from this and lost a chunk of Berserk's effect; causing him to be knocked on his ass when hers swayed back harder than he could match.

Gritting his teeth at the all too familiar sense of concrete against his back, he saw another notification from the system.

'Notice: Site of Evil detected; sending coordinates'

Dexter crawled over to pull her dully smiling face out of the cum.

"You've got a place to raid"

Her focus returned greatly and her smile widened.

"Yes Boss, Let's pound them! I pledge you all the loot"
