Best Friends -4- (Dullahan Warning: Faint of Heart, Block the Illustrations)
I was thinking it might be time to slowly get up when

"Seriously!! Master's cock is all dirty now!!"
"Huh?"
The first one I'd fucked, Dura, had somehow gotten back up already and placed my head on her lap for a lap pillow. Her thighs felt more firm and toned than soft—probably because she used to be a warrior—pressing against the back of my skull.
"The others..."
"Oook...♥"
"Hiiut...♥"
"Gook...♥"
"They're all passed out. Hmph, what a bunch of weaklings."
Dura glanced at the other undeads who couldn't pull themselves together after climaxing, her expression full of disdain.
For a second, I nearly said, You passed out too, but I held my tongue.
"No helping it then♥ Looks like this Dura has to step up and clean Master's cock spotless in their place!!"

-Pop
With that, Dura yanked off her own head. Not figuratively—literally.
Dura was a dullahan, and for aesthetic reasons, I'd kept her head attached up until now. But originally, dullahans had separated heads and bodies. I'd designed her with detachable parts, so it had stayed on fine so far, but she could separate it whenever she wanted.
-Fwoosh!!
"Hehehe♥"
Blue undead fire flared from the cross-section where her head detached, just like any other dullahan. And her severed head grinned with a lewd expression.
It was a grotesque, shocking sight to most, but it didn't faze me much. Guess being undead myself made it no big deal.
"Hehe♥"
Dura set her head, which she held in one hand, down beside my waist and moved her hand.

"Come on, Master, time for some titty feeding♥"
-Stroke
-Slosh
She brushed her hands over her ample tits—not quite as massive as Friss's, but plenty big—pushing her white bikini aside. Her lewd pink areola and nipple peeked out from beneath the thin fabric.

"Here~ suck suck"
-Stroke
She brought the exposed nipple right to my mouth. The stiff peak tempted me.

"Ahmp!!"
"Hehe♥"
A joyful laugh came from her detached head.
"Suck!! Lick!!"
I latched on and sucked her stiff pink nipple.

"Pat pat"
-Stroke stroke
Dura lovingly stroked my head in response. Then,
"Here, Master's personal onahole♥"
With her other hand—the one not petting my head—she grabbed the ponytail of her detached head and brought it to my cock.

"Lick lick"
The head, now close to my cock, stuck out its tongue and started licking the shaft. Where'd that confident look from earlier go? Her head licked away entranced, eyes glazed over.
"Tasty♥ Lick so tasty♥ Suck hehehe♥"
-Slide
Her head, diligently licking away, was soon lifted up by the hand gripping her ponytail. Right to the glans.
-Stroke stroke
"Schlurp schlup!!"
Sucking her mechanically petting body's tits while watching this felt strangely surreal.

"Hahmp!!"
Dura's head engulfed my glans whole.
-Stroke
At the same time, I felt tension in the hand and arm gripping her ponytail. And then,

-Schlup!!
"Mmph!!"
Her arm shoved her head mercilessly down to my pubic bone. My massive cock vanished into her mouth in an instant.

"!!!♥♥"
Her face twisted into an ahegao expression right away—and
-Squirt squirt
wetness dripped from her pussy between her thighs cradling my head.
Wait, how does my whole cock fit in her mouth with her head detached?
The question popped up, but my wicked wisdom supplied the answer right away.
Oh, right, that's how it works.
Not important anyway, so I ignored it.
"Mmph mph!!♥"
Separate from her ahegao head, her hand started moving mechanically again.

-Plunge! Plunge!!
"Schlurp!! Schlup!! Suck!!♥"
Her hand jerked her head up and down furiously, making part of my cock shaft slide in and out of her mouth.
-Drip
My saliva-slick, drenched cock gleamed in the light before vanishing repeatedly.

"Schlup!! Smooch!!♥"
-Plunge!! Plunge!!
-Squish!! Squish!!
It felt just like using a living onahole—the intense, bizarre fellatio continued.
And finally,
"Cumming."
The urge hit, and with my word—
-Plunge!!
"Mmph mph!!♥"
Her hand slammed her head down, shoving my cock all the way in. Moments later—
-Spurt!!
"Mmmph!!♥"
I pumped semen down her throat.

"Mmmph!♥"
-Drip
Obviously, with her head detached from her body, there was no way to swallow, so her cheeks ballooned and semen started leaking from the seal between her lips and my cock.

-Pull
"Mmph!!♥"
Her hand moved again, carefully and slowly lifting her head to pull out my cock while minimizing the leak.

-Drip
Massive amounts of semen began spilling from her mouth.
-Pop
"Pah...♥"
Finally, my cock slipped fully from her mouth, and her hand reattached the head to the fiery neck stump.

-Pop
"Mmph!!♥"
Like assembling a model kit, her head snapped back onto her neck.

-Crunch crunch
It was a bit off-position at first, so she nudged it. Then neck and head fully fused again.

"Gulp!! Gulp!!♥"
Now connected to her stomach, her head started gulping down the semen in her mouth.
-Glug glug
Her throat bobbed, cheeks deflating back to normal. Once they did,
"Pah!!♥"
Dura opened her mouth like taking a breath.

-Drip
Semen still unswallowed coated her tongue, dripping down her chest.
"All good?"

"Hehe, of course!! Lick!!♥"
At my question, Dura flashed a confident yet slutty smile, licking her lips.
"Now, for the next service..."
Her lewd smile cut off mid-sentence.
Because
"Move it, nya!!"
"Kyaa, kya!? Ma'am!?"
Nero, who'd been watching from the corner, shoved Dura aside.
"I've been waiting too long, nya!! Master's cock is Nero's now, nya!!"
"Heh, cute little thing."

"Nyanya meow!!♥"
-Squish squish!!
And so the orgy continued.
"Auu!!"
"Uwe!!"
"Huaah!!"
"Dau!!"
I returned to the central group about five hours after tossing them into the makeshift camp.
"Here are your new family members. Get along."
"Nyanya~"
"Dua!!"
"Huu!!"
"Uuh!!"
"Uhii!!"
Nero greeted the other Living Death casually like old friends, but the other four treated the non-Living Death mid-rank undeads with clear disdain.
Kangjang, Dena, Mari, and Masa appraised the newbies like inspectors.
"These four go under Masa as maids. Lead 'em well."
"Dau!"
At my words, Masa elegantly placed one hand on her chest, lifted her skirt hem slightly with the other, and bowed gracefully.
As mid-rank undeads, the adventurer quartet could get hurt in combat, so they'd handle cleaning, facility maintenance, and assisting the Living Death instead.
This was also the role for the expanding squad of lesser Living Death maids-to-be.
I figured finding corpses for Living Death would naturally yield lesser ones too.
"My cuties evolved, so time to taste those upgraded pussies?"
"Auu!!"
"Uwe!!"
"Huaa~"
"Dau!!"
And so began pussy inspection time.

"Oook!!♥"

"Haaah...♥"

"Ogok...♥"

"Ahut...♥"
"As expected from supreme undeads—their pussy flavor is killer!!"
The four had evolved too, maximizing the best traits of my existing pussies.
Thus, we fully conquered the city in the day since arriving.
"Must you go..."
"Yeah, time to."
Nothing left to gain here. The thick demonic energy lifted my mood, and awakening my heart sword let me freely wield external energy for even greater power here—but goals demanded movement.
"Please don't forget us... our king."
The madam said it with regret.
"I'll call on the promised day. Prep thoroughly till then."
"Yes!"
Bound to me, the ghosts shed their grudge spirit status and could leave the city freely. Battle fodder secured for the Demon King showdown.
Final sex with the madam, a goodbye, and we left the ruined city.
-Fwoosh!!
"Hehe!!"
"Mmph mmph!!♥"
"Mmmph!!♥"
"Mmph mmph mmph!!♥"
"Alright, let's head out again."
[Summoning horses and coachmen]
The Living Death and maids were already aboard the carriage. I headed to the entrance to board.
"Safe driving again."
"Hehe!!"
I requested the coachman and entered the carriage interior.
"Auu~"
"Uwe~"
"Huaa!!"
"Dau!!"
"Nyaa~"
My Living Death had already set a slutty feast for me. As I prepared to enjoy the road orgy—
-Hehe!!
"Hm?"
A mental link from familiar to master conveyed someone addressing me.
"Phantom?"
It was Phantom, the upper-rank ghost undead I'd sent to guard my friends Erika and Kanami.
"Something happen to Erika and Kanami?"
Heat rushed to my head at the thought—
Master!! Master!! Report!! We eliminated the threat to Erika!!
Threat eliminated. No idea the details, but resolved safely. I relaxed.
"But why's your speech like that?"
Phantom usually went "Aaaah... aaaah..." or whatever. And that voice sounded familiar...
-Heehee!!
-Flash!!
The mental link showed not just voice but Phantom's form too.
And there was
"Huh? Uehara Kotono?"

Seigen's lackey, doomed soon, who found me dangling off the cliff and reported to Seigen, dooming me to the abyss. Ninja class bitch.
"Master!! Master!! While saving Erika, we snagged a prime meatbag Master'll love!!"
Her once-brown eyes glowed blood-red, red-framed glasses gone, her usual cold secretary face now wore a wicked, playful grin.
What the hell happened while I was fucking Nero?
...What else? Possession, one of undead's signature tricks.
Next episode side story [Exorcist Ninja Kotono] Stand by!! Or whatever lol
