City of Witches

Chapter 511: A Cooperative Relationship (4)

0% 1.

Siwoo swallowed hard.

Deneb looked delicate and shy, like a wilted lily, her eyes darted away like she was trying hard not to look at him.

Through the slit in her nightgown, he could see the soft curve of her side boob and her slender, deep-set navel.

Her body was curled up like a clueless, innocent girl, completely at odds with what was about to happen.

Her long, lean, all soft curves was anything but innocent.

His little mother-in-law, made of everything that drove men insane, was glowing with an erotic charm that crushed his every expectation.

“.......”

He gripped his cock and gently rubbed it against her lower lips.

The moistness felt from Deneb’s petals clinging to his glans.

The narrow heat between her thighs pulsed against his glans.

“Ah....”

A soft, shaky moan slipped from Deneb’s mouth.

When he looked up, he saw Deneb, who had been avoiding his gaze, briefly meet his eyes before quickly turning her head away.

The bossy, nagging Deneb he knew was gone.

Now, all he saw was a noble young lady, scared and unsure, going through something totally new.

This wasn’t right.

If he kept fumbling like this, they’d end up deep in it—wild, hot sex with no brakes.

His gut warned him; if he didn’t wrap this up fast, things could get out of control.

-Schlick

Her delicate folds, soaked with her juices, opened and gripped the tip of his cock.

“Haaah...!”

Her waist flinched and arched back.

And that was just the head going in.

But it felt hotter than the air on a sweaty summer day, her tightness wrapping around him like a second skin.

At the same time, the pressure was so sharp it felt like he was slipping into a cigar cutter.

She might be wet, but her insides weren’t ready, her body was still tight, that untouched tightness of a virgin not giving way just yet.

Her knees, stuck tight together, finally parted as her face twisted in pain.

Deneb sucked in sharp breaths, clearly hurting.

“M-Mr. Siwoo... ah, it hurts...”

She was lying on her side, legs together—a modified side position.

Due to the structure of the female body, when taking a position where the pelvis narrows, the tightness also increases.

She had likely chosen this stance to minimize exposure, feeling reluctant to spread her legs wide or get on all fours like a dog, but it only made things harder for her.

Siwoo hadn’t even thought about that.

Then again, it’s not like he had much experience going in with barely any foreplay.

Moreover, Deneb’s body wasn’t adequately prepared to take Siwoo’s massive cock from the start.

“Hang on a second.”

“Ah...! Ngh, ahh...! Mr. Siwoo... it really hurts...”

He’d planned to wait and go in slow, but when he saw Deneb’s eyes welling up with tears, he gave up right away.

He couldn’t stand seeing her suffer like that—without another thought, he pulled out.

-Pop!

She’d clamped down so tight, it made a sound like uncorking a bottle when his cock finally sprang free.

“Haa... haa....”

Deneb finally caught her breath, shooting him a resentful glance.

“Ms. Deneb... this isn’t working. Maybe we should try a different position?”

“P-position...?”

“Yes... if you could lie back and spread your legs just a bit...”

“You’re... telling me to get into that kind of vulgar pose?”

Sure enough.

She scolded him immediately.

But she probably wasn’t truly mad.

Deneb always got snippy when she was embarrassed.

“I mean, I thought it was a pretty normal position.”

“But... doing that, Mr. Siwoo... you’ll see everything.”

To worry about such things in the midst of fucking like honeybees—how very Deneb-like.

The mother-in-law still had an air of frustrating propriety about her.

Maybe he should try asking for some foreplay instead?

“If you’re not feeling it yet... maybe I can help you get in the mood. Like last time.”

“You’re not just using this as an excuse to have your fun, right, Mr. Siwoo?”

“Of course not.”

Despite the suspicious question, Deneb’s face froze the moment she heard the words, ‘just like last time.’

After all, one of her most humiliating memories was Siwoo sticking his tongue in her asshole to loosen her up.

“No, that’s... fine. I just need to spread my legs, right?”

“Please.”

“...This is so embarrassing I could die.”

Deneb pouted a little but still obediently spread her legs on top of the cloak-covered bed.

Her long, graceful legs opened up smoothly, like a swan stretching its wings.

And with that, Deneb Gemini’s immaculate pussy, previously hidden by shadows, was revealed in full.

Siwoo couldn’t help feeling a bit awestruck.

Even her pussy carried that same sense of elegance she always had.

The color was unreal—like something you’d only see after heavy Photoshop edits.

Soft, pale flesh formed a smooth mound, tinted with a lively pink that looked like a teasing tongue—no other color dared to invade that sacred space.

Below the plump heart-shaped swell were delicate labia, thin and soft like tulip petals.

A tiny clit, shyly tucked away and barely visible.

It was a perfect mix of clean lines and classy curves.

A refined pussy that somehow looked modern and neat but still seemed like it could melt around a man.

It was mesmerizing—he couldn’t take his eyes off it, like he’d been enchanted.

“...Mr. Siwoo, you’re gonna burn a hole in it staring like that.”

Snapping out of his daze, Siwoo looked down and saw Deneb pouting, clearly annoyed.

Her cheeks were bright red, like she’d held it in and finally had to say something.

“S-Sorry.”

“...It’s fine. It’s not like I didn’t know you were a perv...”

Deneb looked like she was about to launch into a rant, but the second his cock touched her entrance, she fell quiet.

He began to slowly push his hips forward.

“Ah... Ah... Ahh....”

With her legs spread wide, the penetration went more smoothly.

Siwoo’s cock, which had been stopped by her tight entrance before, now slipped into her more easily.

After all, even if it was her first time in the front, Deneb had already taken the tougher route—from behind.

She probably figured out by now how to relax her body properly.

But halfway in, Siwoo felt resistance.

It was her virginity, putting up its final barrier after all those years.

“Ugh....”

“You okay? Want to stop for a sec?”

“N-No... I’m okay... It actually hurts more staying like this. Just... push it in...”

With Deneb’s consent, Siwoo timed it just right waiting until she was fully relaxed, then drove his cock all the way in.

“Kyaa!”

It was a harsh thrust into a pussy still nearly dry, slicked only slightly by her juices.

Deneb jolted up like a deer hit with a shotgun, flailing as she tried to push him off.

But Siwoo leaned forward, pinning her movements down with his body.

If he pulled out now, all of it would’ve been for nothing.

He had to give her body time to adjust, let her tight inner walls get used to his size.

So instead, he gently pulled her shoulders into a hug to calm her down.

“It’s okay... You’re okay.”

“Hng... ugh... uhh...”

Bit by bit, Deneb’s rigid, tense body began to relax, her gritted teeth slowly unclenching.

Maybe her hymen was just naturally thin, but there wasn’t much of a tearing sensation at all.

But as soon as the vaginal mucosa, which had been welcoming the suddenly inserted cock with near-convulsive contractions and relaxations, calmed down...

Siwoo felt like he’d entered a whole new world.

“Haa... haa... hauu....”

Having been intimate with various women, Siwoo knew that just as each person’s appearance differed, so did the sensation inside their vagina.

And judging by how tight her entrance was, he’d expected Deneb’s to be tight and gripping all the way through.

But once he broke through those narrow gates and got deeper inside her, he felt something totally different—an impossibly soft sensation wrapping around his cock.

The hot, melting temperature and the twitching, the vaginal mucosa that felt like it could move anywhere.

Like the inside of a gently roasted marshmallow.

Not loose, not at all.

If anything, it was the perfect wet and snug cunt.

Beyond the tight grip at the entrance that clamped down on the base, even the inner flesh wrapped around Siwoo’s cock without a single gap.

It felt so soft, so sweet, so relaxing, like he could just fall asleep inside her.

Stern as she might seem, Deneb loved her twins more than anyone.

Her deep maternal instinct seemed to show even in the tender flesh inside her.

“Haa... haa... haa....”

Deneb didn’t move an inch, yet her pussy kept twitching around the entrance, rhythmically tightening around his shaft. Her insides softly stroked the tip of his cock like they were flirting with it.

“Are you feeling okay now?”

“Y-yeah, I’m... fine....”

Deneb said in a trembling voice, as if she was extremely embarrassed by this situation.

Well, even though it was an emergency, she was still having sex with the man meant to marry Odile and Odette.

And not just her ass—she’d handed over her pussy to him, too.

A sense of depravity, which she hadn’t even considered during the last verification, now thoroughly soaked Deneb’s heart.

“I think I’m gonna cum soon.”

The pain was shorter than expected, and the unexpectedly sweet pleasure was intense.

Compared to how it felt when he shoved into her ass, like her guts were being pushed up into her throat, this was actually pretty comfortable.

Deneb’s lashes fluttered as she vividly imagined the thick shape filling her up, pressing into her from inside.

Then, the old bed started creaking beneath them.

- Thrust thrust thrust.

“Ngh, mmh... hng...”

Deneb clamped a hand over her mouth, but still let out a string of soft, breathy moans.

Though the body part was different, the fullness she felt was incomparable to the clumsy pleasure of her own masturbation.

The bare skin pressing against hers, the electric thrill of being a noble witch pinned under a man, the raw sensation of their most intimate parts moving together.

It tickled Deneb’s body like a feather.

Deneb had been holding back her moans, but she couldn’t resist the sensation of the head of his cock digging into her depths and rubbing against her womb.

-Squish!

“Aahh...! Mr. Siwoo...!”

Siwoo hadn’t moved that much, but from the beginning, all he’d been thinking about was cumming fast.

He could feel it coming soon, and Deneb’s voice—soft and whimpering—was something she’d never let anyone hear before.

“I’m cumming.”

“A-alright...! Hngh...!”

It wasn’t like the messy, heated sex where you end up all sweaty and cling to each other after pounding away like animals.

His cock still felt everything. He could feel the way Deneb’s bare pussy rippled and pulsed around him, soft and warm.

“Aaah...!”

When she felt his cock swelling up inside her belly, Deneb let out a soft moan.

As the physical and mental pleasure peaked, Siwoo’s hand instinctively grabbed the voluptuous breasts in front of him.

Those tits had been jiggling like pudding through the front of her nightgown, teasing him for a while. Now, they filled his hand completely.

-Spurt, spurt, spurt

“Ah.... Aaah.... Aaah.. .. “

Deneb didn’t even think to stop him. All she could do was feel the thick bursts of cum pouring into her.

She didn’t need to look—her body already knew.

He was cumming inside her.

“Haa....”

It was a spine-tingling, strange kind of orgasm.

When he’d cum in her ass before, it had lined up with her climax, and the orgasm had rocked her. But this time, he barely moved, and the semen spilling into her didn’t do much for her.

She was relieved that she hadn’t shown him her howling like a cat in heat again, but Deneb felt strangely empty.

“Ms. Deneb, it’s almost time...”

“I know... you said the pleasure would come... wait, wha...?????”

Deneb had already started to sense the faint ripples of mana spreading inside her.

She remembered what Siwoo had told her.

That after cumming, along with the mana recharge, a huge pleasure would come.

-Thwack!

Pure mana flooded into her womb, and her back arched into a beautiful bridge as if pulled by a string, something she hadn’t been able to feel properly from insertion to cumming.

Even the inner walls of her pussy, which had been gently cradling Siwoo’s cock, now clenched down hard, milking every last drop from him.

“Big sissss!!!!”

Deneb had sworn she wouldn’t lose control again, but just like before, she ended up calling out for her sister.
