Chapter 12: Deep Throat (No Full Sex)
Author’s Note: Apologies for the delay!
I’ve been swamped with university presentations and midterms, so updates were tough…
…Okay, fine, I was playing games. Blame that RPG with weak assassin elements—it’s just too addictive.
But since some of you actually want to read more of this trash, I put down the controller and managed to finish this chapter.
That said, it was a struggle, so some parts might feel off. Feel free to point out typos, improvements, or share your thoughts!

“Nngh…❤️ Mmmph…❤️ Haaah…❤️”
Before she knew it, Saki had pounced on the throbbing, monstrous cock like a dog in heat, drool dripping from her lips.
Up close, her sister’s “thing” was even more terrifying. Jet-black, thicker than Saki’s wrist, and longer than her forearm—it defied human anatomy. The grotesquely swollen glans alone was beyond comprehension.
Yet, the disgust she once felt was gone. Instead, her womb burned, her chest fluttered, and her instincts screamed at her to submit.
She lapped at the shaft, slurping up the sticky precum coating it. The stench—like a fish tank left to rot for months—filled her nostrils, bitter and overwhelming.
(So this is what it tastes like…?)
Porn made it look delicious, but reality was harsh. Yet, as the bitterness faded, a strangely sweet aftertaste lingered—Rin’s unique, intoxicating scent. Against all logic, Saki didn’t hate it.
Squelch.❤️ Splurt.❤️
—In fact, she came just from tasting it.
(No way…❤️ Just from this…?❤️)
Her vision whited out as her body convulsed, her juices splattering audibly onto the floor.
Of course, there was no aphrodisiac in Rin’s cum. Saki’s body was simply that ecstatic to finally consume it.
“Hah…❤️”
Catching her breath only made it worse. The musk of Rin’s cock flooded her senses, stoking the fire in her core.
She nuzzled against it, her face smeared with filth, her silver hair ruined. But she didn’t care—she wanted to be marked.
The heat radiating from Rin’s cock was scalding, like a branding iron. Mixed with the bitter precum was another smell—sour, unmistakably female.
(That’s… her.)
Saki’s expression darkened.
“Nngh…❤️ Mmmph…!❤️”
She licked aggressively, as if reclaiming territory, swallowing every drop with obscene noises.

[Rin’s Perspective.]
Watching her little sister—her precious, adorable sister—debase herself like this was… intoxicating.
Rin had always admired Saki. Her charisma, her ability to make friends effortlessly—it was enviable. But now?
Now, Saki was just a bitch in heat.
Her silver twin-tails, usually a source of pride, were drenched in cum. Her delicate frame, more doll-like than womanly, trembled as she serviced Rin’s cock with slavish devotion.
And her face—god, her face. Those jade eyes, inherited from their mother, were glazed with pleasure. Her tongue lolled out, her expression twisted into something stupidly lewd.
Rin’s cock twitched.
(My sister… looking at me like this…)
The taboo sent a thrill down her spine.
“Nngh…❤️ Lick…❤️”
Saki obeyed, her tongue swirling around the engorged glans, cleaning every crevice. The bitterness no longer fazed her—if anything, it tasted good now.
“Pwah…❤️”
Finally pulling away, Saki panted, her mouth glistening with spit and precum. Rin’s cock, now spotless, stood at full attention—bigger, meaner than last month.
Saki’s breath hitched.
(It’s… growing…?)
Rin smirked.
“Saki.”
“…Huh?❤️”
Gathering the last scraps of her pride, Saki tried to sound defiant. But the lust in her voice was undeniable.
“Suck it.”
“Wha—?! Why should I—”
“Let me rephrase.” Rin leaned in, her voice dripping with malice. “I’m going to fuck your throat. Open wide.”
The sheer audacity should’ve enraged Saki. But instead, her thighs clenched.
(Yes… please…)
Yet, her pride wouldn’t let her say it.
Rin sighed—then shoved her cock forward.
“Mmph!❤️”
The tip slammed against Saki’s lips, forcing them apart.
“Good girl.❤️ Now, open.”
Trembling, Saki obeyed.
—
Even at full stretch, Saki’s mouth couldn’t take more than a quarter of Rin’s girth. Her gag reflex kicked in instantly, tears welling as her throat was stretched beyond limits.
“Ngh—!❤️”
Rin didn’t care.
“Trying to pull away?❤️”
“—❗❗⁉️⁉️”
Schlorp.❤️
With a brutal thrust, Rin buried herself to the hilt.
Saki’s eyes bulged. Her jaw ached. Her airway was gone.
Panicked, she tapped Rin’s hand—mercy, mercy!
“Hah…! Gah…!”
Pulled back just enough to breathe, Saki gasped, her throat raw.
“No breaks.”
“W-Wait—!”
“Glrk!❤️”
Rin pistoned into her, fucking her throat like a fleshlight.
“NghoOOOH!❤️❤️”
Saki’s eyes rolled back, her body convulsing. Drool and precum bubbled from her lips, her face turning crimson.
“Ahh…❤️ Your throat’s perfect.❤️ Deeper.❤️ Bite me, and I’ll kill you.”
(As if she could bite—her jaw was locked wide.)
“Ngh…❤️ Ngh…❤️”
Eighty percent in. Saki’s neck bulged obscenely, her breaths shallow.
(Am I… dying…?❤️)
Yet, her body burned with pleasure.
She could’ve run. But she hadn’t.
Proof? The flood between her thighs.
(That’s right… I want this…)
To be used. Owned.
Even if it killed her.
“…Kufufu.❤️”
Rin’s laugh was icy.
Finally, finally, Saki surrendered.
She knelt, spread her thighs, and begged.
“Fuck me…❤️ Please, Onee-sama…❤️ Use my mouth… my pussy…❤️ Turn me into your cumslut…❤️”
Rin’s grin was predatory.
“Since you asked so nicely…❤️”
With a yank of Saki’s hair, she slammed home.

Author’s Note: I just realized the “handsome guy” in the title hasn’t gotten any screen time. His name’s Kanzaki Kouki (I think?). Once Saki’s arc settles, I’ll focus on him.
This chapter was all about mouth to cock scenes, but I’m planning more intense scenes—nipple piercings, clit piercings, tattoos… though I’m still debating those. Let me know your thoughts!
Also, anal will happen eventually, but it’s not my favorite, so it won’t be a main focus. What do you think?
