"Mom, hearing Nan Nan's voice gets you all worked up, doesn't it? Sneaking around like this is thrilling, but your son-in-law's feeling a bit neglected again."
Xu Bin planted a kiss on her lips, murmuring softly, "Your son-in-law's a bit worn out, Mom. Can you soothe me now?"
"You little rascal, always full of naughty ideas."
"Mom, I've been holding back all night. If your daughter can't handle me, you're not gonna leave me hanging too, are you?"
Having climaxed three times from his tongue, Shen Ruyu couldn't possibly say no. Despite a fleeting sense of false shame, when Xu Bin gently nudged her head downward, she complied.
Shen Ruyu slid down to her son-in-law's lap, gripping his cock and giving it a few strokes. The scent didn't repulse her; instead, it sent her body into a feverish excitement. Finally, she extended her tongue and began licking her son-in-law's shaft.
There was no disgust, only an intoxicating allure to the scent, brimming with raw masculinity that was impossible to resist.
Recalling scenes from movies she'd watched or the gossip of loose-tongued women, Shen Ruyu, despite her inexperience, licked with audible zeal, free from the awkward fumbling of a naive girl.
Though it was her first time sucking cock, Shen Ruyu carried herself with surprising poise, stealing glances at Xu Bin's reactions as she worked.
Some things seemed to require no experience—as if instinct took over once the blood stirred. Her performance caught Xu Bin off guard, exceeding his expectations.
Shen Ruyu tested the waters, then began sucking his cock, her soft tongue tracing the sensitive ridge of his crown. Her movements were innocent yet seamless.
"Mom, that feels so good!"
"Mom, you've gotta teach Nan Nan a thing or two. She's not nearly as thorough as you."
The flattery, though insincere, delighted the mother-in-law, who started mimicking the motions she'd seen on TV, tentatively taking him deeper.
Xu Bin let out a groan of pleasure, watching his cock slide in and out of his mother-in-law's mouth. The overwhelming desire was beyond words.
Her rosy lips wrapped around his dark shaft—a stunningly provocative sight, made even more so by the fact that it was his mother-in-law kneeling before him. Xu Bin longed to record this, though he wasn't sure who he'd show it to, to boast of this monumental conquest.
Just then, Xu Bin's phone pinged with a message.
Shen Ruyu froze, her eyes darting to Xu Bin with a mix of confusion and anxiety.
"Hubby, don't overwork yourself. Rest early, don't worry about waking me. Come back and sleep in the room, not the living room, or Mom and Big Sis might disturb you."
The tender message made Xu Bin's cock swell even more. Glancing at the stunned beauty beneath him, he whispered, "Mom, it's Nan Nan!"
At those words, Shen Ruyu's delicate frame visibly shuddered.
"Mom, I need to make a call. I'll take the lead now. You know what to do, right? No deep throat, but I'm close to cumming."
Xu Bin struggled to his feet, cradling his mother-in-law's head to keep her lips around his cock as she rose to her knees.
Shen Ruyu felt like she was losing her mind. From this angle, she could see the wedding photo on the nightstand—Yao Baichuan in a gray suit, herself in a daringly modern wedding dress.
She wanted to stop, to refuse. Talking to her daughter while fucking her mother-in-law's mouth was too much—too depraved. Her heart couldn't take it.
But as her emotions churned, Xu Bin, eyes bloodshot with lust, gripped her head and began thrusting into her mouth.
He dialed the phone, putting it on speaker. The first to speak was Xu Bin: "Babe, Mom was asking why I'm wandering around in the middle of the night!"
Shen Ruyu rolled her eyes, discomfort washing over her, but she couldn't speak. She steadied herself, gripping her son-in-law's cock. For the first time, she sucked tightly, enduring each thrust.
"Oh no, Mom texted you? I'm so sorry, hubby, I didn't mean to make her worry."
"It's fine, my bad. I should've told you."
"You were asleep, though. I didn't want to wake you."
"Just some equipment issues. I'm at the internet cafe using their network to troubleshoot. My mistake, really."
As Xu Bin spoke, he licked his lips, staring at his mother-in-law's struggling mouth, unable to resist him. Suddenly, he grabbed her hand and placed it on his balls.
A mature woman was different from a girl. Despite it being her first time, Shen Ruyu, in a daze, began caressing her son-in-law's balls. Her full breasts swayed with each thrust, a breathtaking sight.
"Hubby, I'm sorry. I woke up, didn't see you, and just asked Mom."
"I didn't think she'd go straight to you. Is it messing with your work?"
"You're working so hard, and with the time difference... I'm awful."
"It's Mom's fault for saying so much. I thought you were out with another woman. I'm useless—if you were, I shouldn't ruin your fun."
Yao Nan's genuine guilt poured out, oblivious to the chaotic sounds on the other end.
Her son-in-law's cock plunged deeper into her mouth, the serpentine shaft battering her throat, causing discomfort for the first-time beauty.
Her breathing grew labored, saliva spilling uncontrollably, dripping from her chin and trailing in silvery threads onto her swaying breasts.
"Babe, I'm not out with other women. What're you thinking?"
Xu Bin kept thrusting, gripping her head, gazing down at the stunning mother-in-law kneeling before him, her crimson lips used like a pussy.
She was clearly new to sucking cock but acted practiced, enduring his roughness even when she could barely breathe—a visual feast.
Hearing Yao Nan's gentle voice heightened the thrill for both Xu Bin and Shen Ruyu, who felt unhinged, her body reacting intensely despite the madness.
Xu Bin fucked her mouth harder, his hips bucking, breaths growing heavy and uncontrolled.
"You sound out of breath. What kind of woman would you go for, hubby?"
Yao Nan yawned mid-sentence.
Xu Bin grinned lewdly. "Babe, I saw a chick earlier who looked like Mom—big melons on her chest, just like Mom's."
"If I were picking, I'd go for that type!"
"Ugh, you pervert. I knew you were ogling Mom's chest at home, especially when she skips the bra."
"Hell yeah, I've stripped her naked in my dreams!"
Xu Bin paused as Shen Ruyu, nearly choking, pushed back. After several deep thrusts, the resilient mother-in-law needed a break, though she wouldn't resist unless truly overwhelmed.
She spat out his cock, gasping for air, but her small hand kept stroking, ensuring his pleasure didn't falter.
