The Invincible Son-in-law

The Su Family Sisters and that alluringly beautiful mother-in-law, Peng Yunyan, had long since let Lin Hao open their backdoor.

However, with the sheer number of beauties around Lin Hao, playing with the front was already tough enough, leaving him with no time for the back.

Tonight, it was precisely because he hadn't enjoyed the two sisters for a while that Lin Hao wanted to try something new.

Now that Su Muchen wanted to play as well, why not just go for it?

"Sis, raise your ass up."

Su Muyun actually wanted to help her sister apply the lube.

Though Su Muchen felt a bit worried inside, she couldn't resist the pleasure that the backdoor brought.

Blushing fiercely, she still lifted her ass high, positioning herself in front of Su Muyun.

Su Muyun gazed at her sister's little rosebud, reaching out to stroke her plump butt, her fingers teasing that delicate pink blossom.

At the same time, she grabbed the lube, pouring it directly on her ass, her fingers slowly working it into her sister's rosebud hole.

"Mmm... mmm..."

As soon as the finger slid in, Su Muchen felt an unfamiliar wave of pleasure and started moaning softly.

Lin Hao watched his ex-wife playing with her older sister, not in a rush to jump in; after the rounds of intense action earlier, he needed a break.

After all, the continuous thrusting, both front and back, had put real strain on his waist and leg muscles.

Sitting on the edge of the bathtub, his thick shaft let Su Muchen stroke it as she pleased; he grabbed the lube to help Su Muyun play with her big sister.

Honestly, he'd already fucked all six holes of these sisters, but every time brought a fresh sensation.

Especially since he hadn't played with their backdoor lately—the tightness was at least two or three times what the front could offer.

The two of them worked together—one holding open the rosebud, the other pouring lube. Soon plenty of slickness had seeped in.

Su Muchen felt her rectum cool and icy, working to arch her ass higher, letting the slippery lube slide deeper inside.

Now, all she wanted was that thick shaft inside her. So she opened her mouth wide, took his cock in, and started licking and swallowing.

Lin Hao felt his cock enveloped by her warm, wet mouth, the sensation of tight, slippery pleasure rushing over him. His half-soft shaft surged back to life.

"Mmm mmm mmm... Oh oh... Mmm... mmm mmm..."

Su Muchen tasted him eagerly, letting out sweet sounds of delight.

Su Muyun was having a blast playing with her sister's rosebud, fingers swirling and probing inside, savoring that special kind of tightness.

She wondered if her own backdoor was bigger than her sister's, but Muchen's little rosebud was truly gorgeous—a flower blooming, making it impossible for her to let go.

Lin Hao sat at the edge of the tub, his hand fondling Su Muchen's luscious tits, fingers rolling her tender nipples, clearly wanting to spark off her desire.

His other hand slid between her thighs, fingers spreading her plump pussy lips, plunging into her pussy, working her in and out with skilled strokes.

With all three of her holes filled, Su Muchen found different waves of pleasure crashing together.

Especially the two lower holes—distinct sensations surging through, turning her arousal hotter and hotter.

"Hubby, your little hole is so pretty! It feels soooo good! Later, you gotta fuck her hard—make her cum, make her fly!"

Su Muyun laughed as she spoke.

"Babe, don't worry, I'll definitely make sure sis gets off!"

Lin Hao grinned wide.

"Brother-in-law, later I'll squeeze you to death! Crush your big cock!"

Su Muchen pulled his shaft out of her mouth and gripped it hard in her hand.

"Tsss... take it easy! You'll break it!"

Lin Hao could feel her grip was too strong, making him wince in pain.

"Such a shame Aunt Yun didn't come down. If she had, we'd take turns with you—no way you'd make it out alive!"

Su Muchen grinned wickedly, her eyes twinkling mischief.

Now that Su Dingfang was back, Peng Yunyan couldn't be as blatantly wild with Lin Hao as before.

Honestly, that gorgeous stepmother wanted it just as badly.

But with her husband home, she had to restrain herself—at least a little.

"Sis, you and I alone can drain him dry. No need for Aunt Yun."

Su Muyun chimed in, laughing as she interjected.

"Looks like I haven't properly trained you. Once I'm done with your sister, I'll handle you next!"

Lin Hao spoke as he grabbed a condom, slid it on, then rose to his feet.

Su Muchen switched positions, her hands gripping the edge of the tub, arching her plump ass high.

Lin Hao stood behind her, that thick cock teasing at her tight little back door, rubbing and circling.

Su Muyun jumped in to help, grabbing his cock and guiding it right to her sister's asshole.

Even though Su Muchen had braced herself, the moment the thick head shoved against her ass, a jolt of pain shot through.

But that brief twinge quickly drowned in a wave of swollen pleasure.

Lin Hao's hips pushed forward, and with Su Muyun's help, he slowly pressed into Su Muchen's back entrance.

The wildest, fiercest sensation flooded Lin Hao, making him grit his teeth, barely able to hold back from cumming right then.

Honestly, he hadn't fucked the sisters' asses in so long they'd gotten even tighter.

Lin Hao took a deep breath, his stomach tensing, both hands gripping those full juicy cheeks as he drove his hips in, plunging hard.

Ah—

Su Muchen let out a moan of pure delight, lifting her head, tossing her long silky hair—utterly satisfied.

No doubt about it, that cock was huge. Even with just the tip buried inside, she was overwhelmed by indescribable bliss.

Luckily, after all the lube they'd poured in earlier—and the condom's slickness—it didn't hurt nearly as much.

Lin Hao felt the mature beauty's walls squeezing tight around him, contracting and cradling, working to adjust to his thickness.

The intense swollen pressure and the strange sensation of intrusion tangled together, leaving Su Muchen's scalp tingling from sheer pleasure.

"Relax, sis! Don't be so tense…"

Su Muyun whispered, her fingers tracing circles around her sister's hole, playfully teasing the wrinkled rim.

A shivering, tingling itch made Su Muchen try to let herself loose—but the moment her asshole unclenched, Lin Hao shoved deeper, snatching the opportunity.

This time, Lin Hao lunged forward, burying himself to the hilt, every inch vanishing inside, finally seeming satisfied.

Su Muchen's experience was something else—feeling like her ass had been speared right through, cock rammed all the way up into her belly.

Since the rectum's part of the abdomen, Lin Hao's thrusts felt like he was deep inside her gut.

If you looked closely at the skin just above her lower belly, you'd probably see the outline of his thick cock, bulging inside.

"Fuck, so tight! Feels incredible!"

Lin Hao groaned in rapture, loving how snugly she gripped his shaft.

"Mmm, brother-in-law… you're so deep… ah… don't be so rough… mmm… can't you be gentle…"

Su Muchen whined, a teasing pout in her voice.

"Fine! I'll go slow!"

Lin Hao held her luscious cheeks, slowly drew out his cock, ready to kick things off.
