Chapter 10 Wall-Butt 3P꞉ The Conclusion*
Edited by: Kanaa-senpai
”This time, I took my position behind the dark-skinned succubus. I withdrew my fingers and pressed my semi-erect shaft against her private sanctum.
As if signaling, “Finally, it’s my turn. Big sister is going to make you feel wonderful,” she began to rub her lush petals against my length. The movement was executed with such finesse—almost as if she were licking me with her tongue—that my rod, which had only been halfway revived, surged into a state of complete erection.
Much like a bee hopelessly drawn to nectar, my member was swallowed whole by her flower.
I drove deeper and deeper into her canal. Upon reaching the absolute depths, I felt a peculiar, fine-grained texture against my glans.
Is this a kazunoko tenjo¹? And it’s actually firm.
In that fleeting moment, I conceded defeat. There was simply no way I could endure such stimulation.
I’ve encountered a standard one before with a popular escort, but this was a different beast entirely. I had never experienced ridges so hard and densely packed. This was, without question, destined to feel incredible.
But men are truly pathetic creatures.
Even in a battle we know is lost, if the battlefield is a bed, we will charge in with a smile. That is the nature of the beast.
Still, even for a second round, it would be humiliating if I couldn’t last a single minute. To pace myself, I began moving my hips slowly while leaning over her, kneading her dark-skinned breasts.
Her chest was noticeably softer than the white succubus’s. As I thrust, I stole a glance; despite her dark skin, her tips were a vivid pink—an erotic contrast that stoked the fire.
While I was savoring her breasts and maintaining a slow rhythm, her tail suddenly coiled around my arm. After pulling my hand away from her chest, the tail whipped around to my rear and delivered a sharp, playful slap.
”Alright, I get it. Let’s settle this, then,” I said.
Accepting the reprimand from this ‘big sister’ who refused to let me stall for the sake of my petty pride, I steeled my resolve and sat up.
I gripped her hips firmly and began to drive back and forth with intent.
Every time I reached the back, a staggering wave of pleasure surged through my entire being.
”Guh… this is… I’m not going to last!” I groaned.
As I struggled to withstand the sensation, she finally made her move. Spreading her wings, she began to flutter them lightly, as if mocking my effort or signaling her own enjoyment.
”You’re way too relaxed, damn it!” I shouted.
Seeing her so unfazed made my endurance act feel foolish, so I abandoned all restraint and began to thrust violently.
Her backside, firmer than that of the white succubus, yielded only slightly before bouncing back against every strike.
Caught between that elastic rear and the supreme stimulation of the ridges deep within her, I reached my limit in an instant.
I lunged over her, pinning her down by her breasts as I drove my hips to the very bottom one last time.
”Nngh, it’s coming!” I cried out.
Glide, glide!
A massive torrent of heat erupted from the tip of my rod.
”Ah… h-hah…”
Flow, flow!
Even as I released, the internal ridges continued to writhe and pulse, refusing to stop their assault on my sensitive tip.
I let out a breathless, silent cry as I was milked of every remaining drop.
Once I was completely spent, her tail began to stroke my backside with a gentle, soothing rhythm.
It was as if she were saying, “You did a good job, little boy.”
Instead of being annoyed at being patronized, I simply accepted the loss and withdrew with a self-deprecating smirk.
”Phew…” I exhaled.

I stepped back and flopped heavily onto the bed. Staring at the two rears presented before me, I reached for the sports drink on the nightstand.
The white traces leaking from both of them were the undeniable proof of my instinctual conquest.
It felt great. But there was still one thing left to do.
Yes—the taste comparison.
I checked the clock; only ten minutes remained.
This would be my third round, but with that dark-skinned succubus around, I wouldn’t run out of time like I did yesterday.
She’s the ultimate pleasure tool. No need for finesse; I just needed to let my instincts take the lead.
I used that logic to bury the sting of being treated like a child and drained the rest of the bottle.
Rising to my feet, I returned to the white succubus and took my place behind her.

Over the next ten minutes, I alternated my thrusts between the two succubi, performing a thorough comparison.
As expected, the dark-skinned one’s canal was unparalleled. Within that final window of time, I managed to release twice more.
As the two rears began to fade from view, still dripping with the evidence of my spree, I felt a deep sense of satisfaction. A 3P really is the pinnacle.
However, a lingering restlessness remained. I felt like I wouldn’t be truly satisfied unless I hit five rounds, so I decided to summon just one more back.
And the one who materialized was…
The dark-skinned succubus, her skin still glistening with the white liquid.
”No way, again!?” I gasped, utterly stunned.
She pointed the tip of her tail toward me and curled it repeatedly in a blatant ‘come hither’ gesture.

Faced with such a direct provocation, I realized this wasn’t going to end with a mere four rounds like last night.
With my desire surging back to life, I threw myself back into a battle I was absolutely destined to lose.
