The Heir's Overwhelming Endowment
"L-Like the boss, that's why...?"
Of course, she hadn't been entirely unprepared—after all, the boss was notorious for his love of women. But even so, the sheer size staring her in the face left Mary flustered.
Still, Mary never lacked for quick thinking. She masked her surprise and wariness, reaching out to wrap her fingers around his cock.
Urk.
Kylun let out a slightly awkward sound at the touch of her hand.
"Sis got a lot of experience?"
"Nope."
"...Huh?"
She'd waltzed into his bedroom so effortlessly, taking the initiative like a pro—he'd assumed she was seasoned. But her flat denial caught him off guard.
"Hmm~"
Mary hummed a little tune as she eyed the young master, offering more details.
"I've hopped into bed with plenty of guys, but my missions are mostly assassinations or sabotage jobs~"
And when it came to honey traps for intel, Mary wasn't the card they played. She could do it if needed, but they preferred assigning her the tougher, riskier ops instead.
"Once I'm in bed with the target? I kill 'em before the main event, and mission accomplished~"
Even as she explained, her mind was flooded with thoughts of the massive thing right in front of her.
Is this... for real?
No matter how she looked at it, the insane girth made her hesitate just a bit.
"Ah, where was I? Sure, I've used my hands and mouth a few times. But this hole? Still brand new."
"Of course, before that, I'd loosen them up and put 'em at ease with my hands and mouth first."
As if to prove her words, she lavished his still-tensed, rigid shaft with fervent strokes.
Sluurp.
It gets even bigger from here...
She marveled in shock as it swelled further in her grasp, even as she coaxed it to life.
Throb!
And then it sprang fully erect in response to her touch.
"Whoa..."
A awkward smile—not her usual composed one—tugged at Mary's lips, even in this situation.
"Young master, you've never heard you're huge?"
"Who would I even show it to?"
"Ahaha~ ...R-Right, yeah."
Her hand, which had been working him so diligently moments ago, now measured the fully engorged length.
Can't even gauge it with one hand...
She'd volunteered despite her own inexperience, but now that it was fully hard, her inadequacy wasn't the issue. If anything, it was too big—enough to intimidate even a non-virgin.
"Ah... Aah~~"
Mary stretched her jaw as wide as she could.
She was skilled enough with her mouth, but this was in a whole different league from what she'd handled before. With no prior experience like this, the panic was real.
Mmph...!
She forced her mouth open wide and slowly engulfed the head.
"Whoaaa..."
Of course, no matter how impressive his cock, he was still a virgin. The sensation of a woman's mouth for the first time was pure bliss—he couldn't help it.
Chuuup...♡
Why the hell is it so big... My jaw hurts.
But for her, it was pure torment.
She worked it diligently, mouth stretched to its limit just to fit.
****
...!
With the glans still in her mouth, Mary froze.
"S-Sis?"
She'd managed to get it in, but swallowing deeper felt impossible.
Won't work from above.
Deciding the bottom might be better, she spat out the head.
Puhaah...!
"W-Well, young master prefers the bottom over mouth anyway, right?"
"Y-Yeah?"
"Let's just do it."
At least her saliva had lubed it up nicely.
This should do it.
She slid down onto the bed, assuming a smooth doggy position. Then she tugged the still-flustered young master down with her, positioning him.
"Here."
She spread her unused, pink folds with both hands. Kylun held his breath, drinking in the sight.
"Enough gawking. Put it in..."
She led as calmly as she could, though a faint tremor betrayed her.
No matter how composed she tried to be, remembering that size made tension inevitable. Who knew leaning against the bed's edge could feel so nerve-wracking?
"H-How...?"
"Just feel around—the hole's there if you look. And usually, you grab the woman's waist."
Despite his magnificent tool, the inexperienced young master followed her lead.
His rough, masculine hands gripped her slender waist.
It's coming soon...
Squelch...♡
"Huuuh...♡"
No technique needed for this cock.
Haaah...♡
Just the tip stretching her insides drew a sloppy moan from Mary. Her body quivered faintly, tipping into orgasmic bliss—better than expected.
Her whole frame twitched in pleasure.
To the clueless, inexperienced Kylun, it just looked like ecstasy.
"Y-You okay?"
"You can tell it's fine just by looking. Young master, shove it deeper...♡ All the way."
"O-Okay."
She barely held back the pleasure-melted expression creeping onto her face.
With an awkward smile, she guided him further.
The moment talk ended, she whipped her head away. Her face twisted into that of a pleasure-addled bitch in heat.
Squelch...♡
Sluuuurp♡
Whoa...♡ It's conquering every inch inside.
The enormous, thick shaft.
Its even thicker head scraping and stretching her virgin walls relentlessly.
"Huuuuh...♡"
The cock that automatically wrung animalistic cries from a woman trying to play it cool.
They weren't even in the same weight class.
Good, so good...♡
Even a woman gunning for the next boss's wife melted under the pleasure.
Sluuuurp...
J-Just a bit more...
Plap.
Hngh♡
It bottomed out.
Where her ass had felt nothing before, now his hard pubic bone pressed firm.
But...
Hmm...?
Something felt weak.
The cock wasn't the problem. But the thrust lacked power.
"S-Sis, it's... all in."
Not the ecstasy she'd anticipated.
She'd expected it to crush her depths, steal her breath with overwhelming pleasure—but it fell short.
Technique matters more after all.
She sifted through the stories she'd heard, separating truth from hype.
"Y-Young master? You can thrust harder."
"H-Harder?"
"Of course~♡"
But pulling back mid-sentence let the head drag teasingly against her walls in reverse—total foul play.
...♡
She clamped her mouth shut, slamming her face into the bed to stifle the sloppy moan that cut her words short.
Tremble tremble...♡
His indifferent withdrawal even had more speed, making her whole body shake as she fought the sounds.
Puhaah...♡
The pent-up heat finally escaped her muffled mouth.
She resumed her guidance, barely.
"Of course. Thrust harder."
"H-How hard?"
"How hard? Hmm..."
If she said "a bit harder," this young master would probably add just the barest effort.
That's not what I want. Nor what any woman would.
She needed real force.
But with a guy who'd overcompensate with pointless gentleness, better to unleash him from the start.
"Full power."
"...Sis?"
"The human body isn't that fragile. Just slam everything you've got right into me."
"Th-That much?"
"Yep."
Mary flashed a relaxed smile, reassuring her first-time lover.
But beneath that composure lurked an instinctive hunger—how good would it feel if he really pounded her?
"O-Okay."
"Hoo, huuuh...♡"
She exhaled raggedly, bracing for the impact.
His grip on her waist tightened.
Here it comes.
Smack!
Hngk♡
Huuuuiiiik...♡
Despite bracing, the pleasure surpassed all expectations—she cried out.
Shiver shiver...♡
Electric jolts exploded from her womb, surging through her body and brain like a shock. Her mind went blank white with ecstasy.
Haaang♡ What the hell is this...♡
Squelch...♡
The cock withdrew again.
"W-Wait, young master—"
Smack!!!
Huuuiiik...♡
Her composed moans and smile shattered.
Unable to control it, she dissolved into messy cries.
Desperate, animalistic howls of pleasure echoed on.
The young master was picking up the rhythm faster than expected, reveling in the thrill of pounding a woman.
