Chapter 1640: The Mother-in-law Teaches Her Daughter-in-law 3

But now, the greatest incest was unfolding right before her eyes. She watched as Ye Fei buried his penis deep into his own mother’s pussy. In comparison, her own mother was just his mother-in-law, which made it seem even less significant.

Once that awkward feeling dissipated, Liu Yun’er instantly relaxed, only to be filled with excitement by the live sex scene before her. Her eyes were fixed on the incestuous mother and son, eagerly anticipating their performance.

However, after inserting his penis into his mother’s pussy, Ye Fei didn’t thrust quickly as he had done the last time he fucked his mother. Instead, he thrust slowly and intermittently, while burying his head in his mother’s chest to continue suckling.

In this way, even Liu Yun’er, an outsider, felt anxious on behalf of Liu Yiru, not to mention Liu Yiru herself. The son’s suckling and simultaneous fucking excited her, but his lackluster thrusting caused her great discomfort.

She couldn’t help but coo, "Naughty boy, don’t just focus on suckling. Give your mom’s pussy a few hard thrusts with your dick. Mom’s pussy is so itchy!"

"Mmm!" Ye Fei responded with his mouth full of nipple, increasing the speed slightly but still not vigorously.

After a moment, Ye Fei finally drained the milk from his mother’s left breast, released the nipple, and instead of immediately moving to the right one, he pinched the large breast gently, causing white milk to gush out from the nipple.

"Yun’er, come and taste it. Mom’s milk is really delicious," Ye Fei turned to Liu Yun’er, who was watching.

Liu Yun’er was genuinely tempted by Liu Yiru’s breasts, which were the envy of all women, especially now with a few drops of milk clinging to them, making them even more enticing.

But since she wasn’t very familiar with Liu Yiru, she felt shy about tasting her milk and shook her head, saying, "No, thank you. You enjoy it."

"Well, I won’t be polite then," Ye Fei immediately leaned down again, opened his mouth wide, and sucked in about a third of his mother’s right breast, then began to suckle vigorously.

As a result, milk no longer flowed from Liu Yiru’s breast but sprayed directly from the nipple, shooting into her son’s mouth.

The sensation was somewhat painful but mostly pleasurable, a mix that made her almost unbearable, and she couldn’t help but cry out, "You naughty boy, be gentle, oh, but harder!"

Although Liu Yiru’s words were contradictory, even Liu Yun’er, the onlooker, could tell that she wanted her son to suckle more gently but fuck harder. However, Ye Fei seemed to miss the hint entirely, continuing to suckle vigorously while maintaining a leisurely pace with his thrusting.

Under such intense suction, the milk in Liu Yiru’s right breast was soon drained. Ye Fei finally released his mouth with a satisfied smile and said, "Mom, your milk is just so delicious!"

"Are you full?" Liu Yiru looked at her son with a teasing smile.

"Full!" Ye Fei nodded.

Before Ye Fei’s words had even faded, Liu Yiru suddenly lifted her long, sexy legs and wrapped them tightly around his waist. With a forceful twist, she switched positions with her son, pinning him to the bed while she straddled him.

Once on top, Liu Yiru placed her hands on her son’s chest and began to rock her body violently. Her big buttocks swayed left and right, thrust forward and back, and moved up and down rapidly, slapping his lower abdomen with a "slap-slap" sound.

She shouted, "You... disobedient son... only caring... about your own pleasure... suckling so hard... but unwilling... to fuck Mom properly... making Mom... so uncomfortable... now... it’s Mom’s turn... to ride you... to use my... slutty pussy... to milk you dry..."

Watching Liu Yiru’s sexy big buttocks twist like a motor, actively using her pussy to ride her son’s penis, Liu Yun’er was left speechless. She never would have imagined that Liu Yiru, who was truly a goddess-level beauty in both appearance and temperament, could have such a lascivious.

However, it was precisely because of this that Liu Yun’er could imagine just how pleasurable it must be to be fucked like that.

This reminded her of the time when her own mother, despite her strong resistance, eventually lost her mind and became wild under Ye Fei’s big penis.

Thinking of the two mothers’ performances, Liu Yun’er couldn’t help but become even more excited. She instinctively squeezed her legs together and realized that her crotch was already soaked.

Although the sex was very pleasurable, the mother and son did not forget the real purpose of coming to Liu Yun’er’s room. Therefore, Liu Yiru did not hold back, and Ye Fei did not either. They both reached their climax in less than ten minutes.

"Yun’er, Auntie was just too pleased with the sex and acted a bit strangely. I didn’t scare you, did I?" After the climax, Liu Yiru lay limply on her son’s chest and turned to ask Liu Yun’er.

To be honest, at first, Liu Yun’er was indeed a bit frightened by Liu Yiru’s frenzy. But after thinking it through, she no longer found it strange and even envied Liu Yiru for her pleasure. So she shook her head and said, "No, my mom was like that too."

Liu Yiru smiled and said, "It’s not just us. If you two have sex, you’ll be the same. Who can blame it? My son, your husband, has such a big and powerful penis."

"Mmm," Liu Yun’er made a sound quieter than a mosquito’s buzz, blushing and lowering her head. Although she had just witnessed the intense battle between the mother and son, discussing Ye Fei’s penis with Liu Yiru still made her very shy.

At this moment, Ye Fei said, "Mom, my penis has become hard again from your pussy. I want to fuck you again."

"No way. Yun’er has been so understanding and hasn’t stopped us. I can’t keep monopolizing you. It’s time for you to fuck her," Liu Yiru said as she slowly stood up, allowing her son’s big penis to withdraw from her extremely eager, wet pussy.

"Pop"! With a soft sound, Ye Fei’s penis finally came out of the pussy. Liu Yiru’s pussy, no longer blocked by the penis, immediately gushed out a large amount of clear liquid, which all splashed onto her son’s erect penis.

This strange sound made Liu Yun’er, who was lowering her head, look up subconsciously. She saw Ye Fei’s penis, covered in his mother’s juices, glistening under the light, looking quite intimidating. But to her, it was incredibly enticing.

Ye Fei turned his head and looked at Liu Yun’er, smiling and asking, "Yun’er, are you ready to be fucked?"
