The younger brother continued to thrust his thick penis in and out violently.
His perfect penis moved quickly, all the way to the end with each thrust, and the violent impact made Aunt Lu's plump buttocks tremble violently.
Seeing Aunt Lu's plump buttocks trembling, the younger brother became even more excited, thrusting his penis even faster in and out of Aunt Lu's cunt.
To cooperate with my younger brother, I vigorously kneaded Aunt Lu's full breasts, my erect penis rubbing rapidly between them.
My brother and I had only one goal at that moment—to ignite the lust within Aunt Lu, to make her confront her wanton side, and to abandon the mask of nobility she had worn for so many years.
With my brother's perfect penis thrusting powerfully into her, and with my cooperation, Aunt Lu's lust reached unprecedented heights.
Her full, round buttocks swayed vigorously, responding to my brother's thrusts.
Aunt Lu had only been with two men before: Uncle Lu and Shaoqing.
But with either of them, Aunt Lu dared not fully unleash her desires. With Uncle Lu, it was because she loved him too much and didn't want him to know about her wanton and base side.
With Shaoqing, it was because he was her biological son; deeply ingrained morals made her feel guilty even while enjoying the pleasure, preventing her from fully experiencing it.
But this time, facing my brother, and the brother who had discovered her true nature, she began to try to fully enjoy the pleasure of sex.
If Yin Yin hadn't been there, she would have definitely screamed wildly.
After her brother gave the order, Aunt Lu tightly covered her mouth.
She knew that if she let go now, she would definitely scream uncontrollably, loud enough for Yin Yin to hear.
Her image of a perfect mother would immediately crumble in her daughter's eyes, and she would have no right to discipline her daughter anymore.
My brother and I, knowing her concerns, exchanged a smile and carried her several times to the depths of the woods behind the Martial Alliance.
After landing, my brother wrapped Aunt Lu's legs around his waist, supporting her full buttocks with his hands, and said while fucking her, "My wanton mother-in-law, now that no one's here, you can scream loudly!"
Hearing my brother's words, Aunt Lu, who had been suppressing herself for so long, could no longer hold back. She vigorously twisted her full buttocks and screamed wildly.
"My...good son-in-law, your...big cock...is fucking me...so good! I...love being...fucked by my son-in-law's...big cock! Good son-in-law, I...am willing to let you...fuck me for a lifetime, I...am willing to...be your bitch!"
Aunt Lu shouted with an extremely excited expression.
"You old slut, you're like a saint when you're fucking your husband, but like a prostitute when you're fucking your son-in-law, you're so shameless! I'm going to fuck you to death!"
The younger brother shouted excitedly while fucking.
"Oh~~~~I am a shameless prostitute, I am a prostitute who likes to be fucked by my son-in-law's big cock! Good son-in-law, fuck me to death!" Aunt Lu shouted wildly.
Just as the two were frantically fucking, I looked at Aunt Lu's anus, which was wide open due to the position, swallowed hard, and then came behind her. I grabbed her plump buttocks with both hands and pressed my erect penis against her anus.
After realizing my intention, my brother cooperated and temporarily stopped fucking, while Aunt Lu waited expectantly and nervously for my penis to enter.
"Nephew Tianxiang, be gentle, Aunt's been used like this before!" Aunt Lu said, blushing.
Hearing Aunt Lu's words, my eyes immediately lit up. I slapped her big buttocks hard and said to her with a wicked smile, "You slut, you haven't let your husband fuck your anus in all these years, and now we're deflowering you. Did you deliberately leave your anus for your lover to fuck?"
My words made Aunt Lu's face turn red immediately, but it was truly a red of excitement.
She wiggled her hips, rubbing her anus against my glans, and said, "Yes! I deliberately left my anus for you to fuck! I'm a slut who wants her lover to deflower her!"
As soon as she finished speaking, my erect penis thrust hard into her anus.
"Ah~~~~" A cry of seven parts pain and three parts excitement rang out as my penis entered.
"Auntie, your anus is so tight, so comfortable! It feels so good gripping my penis!" I said, holding her plump buttocks.
"Mmm~~~~ My penis is so powerful, it went all the way into my anus in one go!" Aunt Lu quickly adapted to the pain of losing her virginity in her anus, and then said in a seductive tone.
"Hehe! Now let Auntie try the feeling of being fucked by two penises at the same time!" I said with a wicked smile.
After I finished speaking, my brother and I immediately began thrusting in and out of Aunt Lu's cunt and anus simultaneously. "Slap slap slap slap..." The crisp sounds of flesh colliding echoed through the woods.
"Ah~~~~ So good! Fuck her cunt and anus together, it feels so good!" Aunt Lu cried out loudly, shaking her hips vigorously.
My brother and I, supporting Aunt Lu's plump buttocks, enjoyed the service of her virgin anus, excitedly fucking this beautiful and noble mature woman.
Amidst the sounds of bodies colliding, Aunt Lu continued to moan and scream loudly.
My brother and I, on the other hand, shouted with excitement.
When we finished our lovemaking, my brother and I had both ejaculated three or four times; the morning was almost over.
The three of us lay naked and languidly together, enjoying the afterglow of our release.
"Mother-in-law, do you regret letting your son-in-law fuck you? You're not a virgin anymore!"
My younger brother, with his limp penis between her plump buttocks, asked with a wicked grin, his arms around Aunt Lu from behind.
Hearing his question, Aunt Lu smiled coquettishly, leaning against him, and said, "I regret not letting my good son-in-law fuck me sooner. Being able to let my son-in-law fuck my cunt and asshole is the happiest thing for me! Also, from now on, when there are no outsiders, don't call me 'Mother-in-law,' call me by my name. I'll be your concubine from now on."
Aunt Lu looked at my younger brother tenderly as she spoke.
"And what about me? I'm the man who deflowered your asshole! You'll be my concubine too!" I said, touching Aunt Lu's cunt, still dripping with my brother's and my semen.
"No! If I were your wife, you wouldn't know how many men you'd have to play with me! Even though I've become a slut, I still have to think about the Lu family's reputation! Forget being your concubine, even if I were just a little close to you, everyone would know I'm a shameless slut!"
Aunt Lu immediately said to me.
After hearing Aunt Lu's words, I immediately pouted.
I couldn't do anything about this outcome. Everyone in the underworld knew that my father and I were sluts who liked to be cuckolds.
Any woman from our family was guaranteed to be a whore ridden by a thousand men and fucked by ten thousand.
