Chapter 90: Nee-san’s first time (II) (Patreon)

She released another hot sigh. “Your thing will ravage me even if I refuse.” 

She was correct since my arousal was over the limit now.

“Hehe, you got no choice. Your little brother will claim your virginity.”

I got up on my knees and slid down her sexy panties. Shizuka opened her legs and untangled her lower lips with her index and middle finger, allowing me to easily slide the tip inside.

She winced painfully. I leaned over her and pecked her lips. “Tell me when you can't bear it.”

She revealed a gentle smile and hugged my neck. “Nee-san… is a lot stronger than this. Continue…”

I nodded and entered deeper as slowly as possible, stopping when her face cringed. She was tight and slippery. Her slippery walls gripped my cock as I met some resistance, which might have been her hymen.

This was one of the reasons I liked the missionary position for a woman’s first time. I could stop when she felt too much pain.

I eased a little before slipping further inside, bypassing the seal in the process. Shizuka bit her lips as tears pooled in her eyes. I kissed her again in an attempt to comfort her pain, to which she closed her eyes and wrapped her legs around my waist.

As I ended the kiss, she embraced me with every bit of her strength, squeezing her melons against my chest.

“What—”

She blew a hot sigh on my ear, making me shiver.

“Aa-kun~,” She teased. I could imagine her foolish grin at the moment.

At least she wasn't in pain anymore. 

“You lewd woman. I am gonna mess you up now.”

She licked my earlobe in response. “Kekeke, Aa-kun is more experienced than nee-san. But… nee-san will show why they say a woman in her thirties is the thirstiest one.”

She twisted her body and her walls suddenly clenched my cock, stopping any sort of movement.

“See… Rika taught me some tricks yesterday.”

Tainting Shizuka’s innocence—Rika will pay for it later.

“I am gonna move, okay?”

“Um… Aa-kun, don't hesitate to mess up nee-san’s body.”

I ramped up my movements. Perhaps thanks to her high stats compared to normal people, Shizuka let out moans devoid of any pain, only pure pleasure.

Being pinned under me, she could only cling to me and moan my name as I slowly but surely learned her weak points. Occasionally, she moved her hips to increase the tightness of her pussy.

I wanted to see her lewd, messed up face but she resisted by hugging me harder, rubbing her sweaty body against me.

“Not now… please, nee-san is embarrassed...” She begged.

Sex is not embarrassing, huh?

Woman… I can never understand them even after fucking 102 of them.

“Fine.” I gave up. “You can only be selfish this time.”

“Un. Nee-san will try.”

I took my grudges on her pussy, rapidly attacking her sweet spot. Soon, the heat built up enough to make me groan while Shizuka’s moan became hoarse with her inside twitching, waiting to suck me dry.

“Aa-kun, cum inside~! It’s my, umm, safe day!” She whispered in my ears.

I fulfilled her desire and unleashed my lust inside her womb—a giant load of hot cum.

“Aa-kun’s love… is filling me up,” She said and her hands lost strength.

I took this chance to break free and witness her current expression. Her tongue stuck out, gasping for air. Tears smeared on her red face and her hazel eyes drunk with pleasure was the very definition of ahegao face.

The corners of my lips lifted up in a devilish grin. “Did your brother’s cock send you to Utopia?”

Shock briefly crossed her face before she covered her face. “Y-You broke your promise.”

Supporting myself with one hand, I used the other to peel off her hands to reveal her face. “That expression, any man will be happy to see on his woman’s face after they had sex. It’s basically screaming ‘I am satisfied’. So don’t hide such a lovely expression which boosts my pride.”

She uttered some strange sounds and nodded her head. “You bully…  Why are you hard again? Don’t men go limp after doing it once or twice?”

“Not me, I can shoot all day if it’s with my nee-san.”

She showed a smile looking pleased. “Flattery won’t get you anywhere since I am already yours.”

“Okay, okay. I understand. Can you keep going?”

“I can, no I must satisfy the thing twitching inside me. Nee-san’s pride as a woman is on the line!”

“Idiot, don't think you are the only one. I can grab any of the girls to do it.”

“B-But I am also your woman.”

“You stubborn women.”

“I won’t back down…” She pushed me off and sat up with a sigh. “Let nee-san do the moving for once.”

I glanced at my cock glowing a little stronger than last time. The strange thing was it only glowed when I took a girl’s first time. Not when I had sex with them for the second time.

I laid on my back and Shizuka mounted me. Her entire body shone with sweat, emphasizing her sinful figure.

She placed her butt over my cock and lowered it, taking in the tip and gradually the whole thing inside her tight hole.

“O-Ou…” She gasped, her voice stuck in her throat.

She bent toward me, shoving her boobs in my face. I bit on them while pinching the nipples between my fingers.

Moans of pleasure left her mouth as she twisted her hips, moving back and forth. Her intense thirst was contrary to the fact she was just a virgin minutes ago with an intact hymen.

The sex drive of a woman in her thirties is strong.

I kept toying with her divine boobs while she rode on and on until we came together.

The immoral feeling of cumming inside my blood-related sister made this thing even more satisfying.

She laid on my chest, breathless with my cock inside her.

She hit her limit, I guess.

“Nee-san, you did we—”

*Creak*

“Dear son-in-law~, I have—”

I turned my attention to the door, where Yuriko stood with an enthusiastic smile. However, soon that was replaced with a slack-jawed expression when she looked at our state.

Any mother-in-law will be shocked to see her son-in-law balls deep inside his sister.
