Chapter 203: In The Mouth...

Luis began thrusting his hips, treating her little mouth as if it were her pussy.

This was the first time Nancy had ever felt so passive.

That sense of powerless submission made her cooperate obediently with her brother-in-law, tightly enveloping the rigid member in her mouth.

"This is amazing, big sister, your mouth feels so good."

Luis let out a beast-like, hoarse growl, his movements growing faster, though he dared not thrust too deep. But then Nancy’s small hand gently caressed the man’s stiff, twitching testicles.

The fairy-like, enchanting sister-in-law’s mouth was being fucked, drawing out uncontrollable moans and whimpers. Saliva dripped down her chin, some even splashing onto her breasts.

This stimulation was immense for Luis. He could no longer hold back, roaring hoarsely, "I’m coming, big sister, keep it tight."

Nancy whimpered nervously and shyly, pushing against Luis. She had already said no to a mouthful, but even though she was willing in her heart and tempted to try, her tsundere nature meant she had to put up a token resistance. This time, to complete the task and feeling the training had laid enough groundwork, Luis wasn’t about to let her go.

He held her weakly struggling head in both hands and thrust vigorously, despite his sister-in-law’s nearly useless pushing.

His vision went dark, his spine began to tremble, and as his testicles throbbed, a wave of pleasure surged from his lower body, traveling along his central nervous system and stimulating every cell in his body. Every cell seemed electrified by dopamine.

The thrill of coming in his celestial sister-in-law’s mouth magnified the pleasure countless times in that moment, making it feel infinitely better than ordinary sex.

"Here it comes..."

Pressed deep into her throat, Nancy frowned in discomfort, her body completely limp.

Then the flesh in her mouth began to pulse. Before she could react, the head swelled almost a full size larger. The slit opened, and scalding hot semen, thick as magma, flooded into her pretty little mouth.

That same little mouth that had once been sarcastic and uttered so many cutting remarks—so beautiful, yet now it knelt beneath his crotch, filled with his cock, stuffed full of his seed.

In that moment, Luis felt as if he had ascended to heaven. The physical ecstasy, coupled with the emotional surge, was amplified beyond measure.

His hands clamped tightly around his sister-in-law’s head, ignoring her feeble struggles as he continued pumping his hips, again and again, emptying every last drop of his cum into her mouth.

Nancy was nearly suffocating, tears welling in her eyes, but under this assault, she could only swallow her brother-in-law’s thick semen unconsciously.

Earlier, during her tentative attempt, she hadn’t felt any resistance at all. Now, even though she was being treated roughly, she wasn’t angry—she could only keep swallowing, already somewhat addicted to his scent.

Gulp after gulp, Nancy looked up at her brother-in-law’s face, twisted in pleasure, and suddenly felt an indescribable sense of accomplishment.

This pervert... still so hard even after coming.

The second time, and he came so much...

Not only was her brother-in-law’s semen thick, but the volume wasn’t any less than the first time. The potent male hormonal scent intoxicated Nancy, her whole body burning, ignoring the discomfort of her first forced oral climax.

"Big sister, you’re amazing!"

After Luis came, his vision darkened and his legs weakened. He collapsed weakly, gasping for air, his body still twitching uncontrollably now and then.

Nancy spat out the cock, licked the semen from the corner of her mouth, and panted heavily, lying down as faint retching sounds escaped her.

"Bastard... you’re going to kill me, I said no cum in my mouth..."

Though she wasn’t the least bit angry, a fairy being defiled had to show some outrage—that was only natural.

Nancy wasn’t like Lily, with her gentle, docile nature...

And she was highly competitive; she didn’t want her brother-in-law to see that not only was she unbothered, but she was somewhat sinking into this rough treatment.

"Sorry, big sister, it felt too good, I couldn’t control it."

"Bastard... my mouth is sore."

Nancy ran into the bathroom with a pained expression. It seemed her panties were soaked through, and she needed to change her pad.

Thoroughly satisfied, Luis didn’t follow her in. Licking his lips, he felt dreamily content. Today, he hadn’t only enjoyed his sister-in-law’s oral service but also the bliss of facial and mouth-filling climax.

For her, this was already pushing boundaries. Of course, Luis’s coercion gave her a plausible excuse to yield, which also helped preserve her little dignity.

He couldn’t push further now.

Luis lit a post-sex cigarette and, after doing this, dismissed the idea of joining her in the shower right then.

Nancy stayed in the bathroom a long time. When she emerged, she was clearly freshly washed, but she’d put that bothersome bathrobe back on.

"Big sister, why are you wearing that again?"

"Nonsense, I’m afraid someone might go back on his word and start misbehaving again."

Blushing deeply, Nancy kicked Luis and said, "You go wash up too."

She was acting furious, so she needed a little coaxing.

Luis lifted her chin for a kiss, but she dodged away disdainfully. He just chuckled and headed into the bathroom to clean up.

When he came out, Nancy was already buried under the covers.

That troublesome bathrobe was tossed aside.

She hid her body under the quilt, revealing only her slender arms and sexy collarbones as she played on her phone.

Seeing Luis emerge bare-assed,

her face reddened, and she snorted, putting on an I’m-furious act. Luis grinned and made to slip into her bed.

Nancy kicked out at him, saying, "Get away, I need to choose pictures."

"Wouldn’t it be better to choose together?"

Luis caught her delicate foot, kissed it, his face still wearing a lecherous grin.

"Stop messing around!"

This time Nancy’s tone was coquettish. Seeing Luis still looking so lust-driven even after two rounds, she felt both secretly pleased and helpless. Gritting her teeth, she said,

"My period’s here and it’s already uncomfortable, and you keep groping me—it just makes it worse."

"If you keep this up, I’ll get my own room to sleep in."

Though she wasn’t truly angry, she said it seriously—a sign of greater intimacy toward him. Luis stopped fooling around, sat on the edge of the bed, lit a cigarette, and teased, "Big sister, are you just not used to someone holding you while you sleep?"

Nancy nodded slightly and said softly, "Your brother-in-law and I have had separate rooms for a long time now. Honestly, it was novel at first, but later I realized it’s just more comfortable sleeping alone."

"That’s true."

Gazing at his divinely beautiful sister-in-law, Luis couldn’t help saying, "Big sister, I want to ask you three questions. Answer them truthfully, and I won’t harass you tonight, okay?"

"Really?"

Nancy looked skeptical.

"Really. I swear—if I’m lying to you, may I never get hard again."

Luis quickly added, "But you have to swear too—everything you tell me will be the truth, no lies."

"Fine!"

Nancy agreed resolutely.

After all, with her period here, being constantly teased and fondled was truly agonizing.

Even if Luis did nothing, just smelling her brother-in-law’s scent and touching his strong body made Nancy feel her desire stirring restlessly.

Luis took a heavy drag of his cigarette and leered, "Big sister, first question—has your husband ever fucked your mouth like this?"

Nancy froze, not expecting Luis’s first question to be so vulgar. Her face flushed crimson, she gritted her teeth, shot him a fierce glare, then lowered her head in thought.

Knowing her competitive nature, Luis immediately provoked, "Big sister, if it’s too embarrassing, you don’t have to say—just don’t lie."
