The Invincible Son-in-law

Chapter 646: In Youth, Unaware of the Charm of Mature Women

As soon as Su Muchen and Su Muyun, the sisters, saw what was happening, they immediately started stoking their stepmother's desire, reaching out to grab her twin snowy peaks and kneading them.

At the same time, Lin Hao picked up the vibrator and thrust it into Peng Yunyan's Fairy Cave from below, then flicked on the switch.

Bzzzzzz...

The vibrator buzzed, stimulating her secret passage and clit, waves of pleasure crashing in and balancing out Peng Yunyan's pain.

Lin Hao slowly pulled out the big rod, not taking it out all the way, instead smearing more lube over it, hoping it would make her inside feel less tight.

With the lube coating the rod as it pumped in and out repeatedly, it naturally seeped into the intestine, working wonders for smooth thrusts.

Still, Peng Yunyan's tightly closed Ju Men remained fiercely restrictive, and the head of the rod couldn't fully enter, barely a third in at most.

"Ah... so good... so tight... don't take me from behind... ah... do it in front... ah ah ah..."

"No... ah ah... no... it hurts... it really hurts... ah ah ah..."

Peng Yunyan would rather let Lin Hao do her up front a few more times than let him open up her rear pavilion, and couldn't help screaming out.

Lin Hao loved hearing women plead and fight back—those sounds and struggles intensely satisfied his urge to conquer.

So he relentlessly pounded her Ju Men with short thrusts, letting Peng Yunyan's body gradually adjust to his girth.

Peng Yunyan felt herself ripped open again and again, her tightest spot stretched wide, the pain making her tremble all over, her face pale.

"Aunt Yun... so tight... so good... bear with it... I'm coming in..."

Lin Hao couldn't take it anymore. With a powerful thrust of his hips, he rammed the rod deep into her core.

Ah—

Peng Yunyan screamed in agony, craning her neck desperately, eyes wide in shock, tears forming, her mind going blank.

Lin Hao felt the rod slide all the way in, buried inside the mature woman's body, but that tightness at her Ju Men nearly made him feel like she'd snap his cock in half.

Just as she squeezed him hard, Lin Hao almost reached his breaking point; thankfully, he took a deep breath and managed to hold back.

"It hurts... you're ripping me apart... you bastard... you're actually playing with my... asshole..."

Peng Yunyan broke out in a cold sweat, face twisted in pain, cursing him out.

"Aunt Yun, it'll feel amazing soon!" Lin Hao laughed, soothingly.

He withdrew the rod a bit and started grinding it back and forth in short strokes, letting the lube saturate the passage and helping the mature woman adjust to his immense size.

With these back-and-forth thrusts, the pain Peng Yunyan felt somehow transformed into an utterly new pleasure.

The pleasure came from the rod thrusting through her gut—it was nothing like having it in her secret tunnel, not quite as intense, but much more tangible as she felt his cock moving inside her body.

It felt like his rod was spearing right through her, and the sensation struck her as fresh and exciting—the pain didn't seem as bad anymore.

Especially with the vibrator working her in front, the pleasure surged in waves and drowned her entirely.

Su Muchen and Su Muyun kept teasing their stepmom's nipples, making her desire mount higher and higher.

"Lin Hao... move... I think... it doesn't hurt much now..."

Peng Yunyan felt herself get used to his big rod, wanting Lin Hao to go harder.

This time, Lin Hao drew it out all the way, then plunged back in; sure enough, it glided much smoother than before.

Still, the gripping tightness from her Ju Men made Lin Hao feel even better—it was that sweet spot of tight with just enough give, pure heaven without getting injured.

"Aunt Yun, just relax and it won't hurt so much!"

Su Muchen kept working her nipples as she spoke.

Su Muyun chimed in to comfort her, "Yeah, Aunt Yun, just relax. You'll feel good in a minute!"

"You two little brats... helping him do this to me... just wait till I get my hands on you next time..."

Peng Yunyan huffed, reaching over to grab Su Muyun's soft peaks and giving them a rough squeeze.

"Aunt Yun, here I come, brace yourself..."

Lin Hao said, then pulled his ass back, drawing out the rod, and drove his hips forward, thrusting it back in deep.

"I can take it... do it... mm... ah... ah..."

Peng Yunyan bit down hard on her lips, moaning through the pain, fighting to relax her body.

She could feel the big rod—like a red-hot iron bar—driving through her inside, the sensation unfamiliar, a mixture of pain and sharp pleasure.

The feeling was nothing like being taken in her Fairy Cave—much more delicate, tinged with pain, yet some hard-to-explain pleasure flickered around inside her.

The worst part was that Lin Hao kept control of the vibrator in front, doubling the pleasure: from her secret passage and her Ju Men behind, the sensations crisscrossing and whirling together.

Two completely different pleasures raced through her lower body, spreading to every cell until she couldn't even tell which one was stimulating her nerves.

"Ah... so good... mmm... so nice... ah ah... I can feel you inside me..."

Peng Yunyan's arms went limp, her head dropping to the bed, arching her ass up even higher.

Lin Hao had buried his whole length inside his mother-in-law's gut, well-lubricated and squeezed tight, that intoxicating sensation surging from below and filling every cell in his body.

Youths have no idea how wonderful a mature woman is!

Mistakenly taking a maiden for treasure!

Turns out a mature woman's rear pavilion is even tighter than a virgin's first time, it was pure ecstasy for Lin Hao.

Honestly, most couples don't dare to open up that back door at first, but after a decade or more of marriage, all the passion fades away.

If, at that point, the wife would let the husband open the rear pavilion, their sex life would get much happier—and their feelings would be stronger too.

"Aunt Yun, you're so tight, I feel like I'm all the way in your gut!"

Lin Hao voiced what he was thinking, even more excited now.

"Mmm... good son-in-law... fuck me... fuck me to death... ah ah ah... so good..."

Peng Yunyan's eyes rolled back, her mind empty and numb, all instincts focused on savoring the double waves of pleasure.

Su Muyun and Su Muchen heard Aunt Yun calling Lin Hao son-in-law, exchanged a glance, both suddenly flushed with shame.

Especially Su Muyun, the ex-wife, thinking of her ex-husband violently pounding her stepmom's back door right in front of her, made her body burn with incestuous excitement.

"Honey, I want it..." Su Muyun hurriedly stuck her ass out towards him.
