Outside the door, Wen Ting crouched sneakily behind the frame, her delicate hand covering her mouth in shock, eyes wide as she watched the scene unfold.
When her sister spit out her brother-in-law's cock, then took it back into her mouth, sucking that monstrous rod with a look of pure bliss, Wen Ting was utterly stunned.
In Wen Ting's mind, her sister was a prim, elegant woman obsessed with cleanliness, always reserved and proper.
But what she saw today completely shattered her image of Wen Wan.
The sight of her sister sluttily sucking off her brother-in-law seared into Wen Ting's mind, so thrilling she couldn't bear to blink.
Wen Ting's curiosity was insatiable, and the voyeuristic rush made her desperate to keep watching, even leaning forward, eyes glued to the way her sister's mouth fucked her brother-in-law's cock.
"Could it be… could it really be that sister loves sucking him off… that it feels good… like he said?" Wen Ting's big, watery eyes widened, recalling how her brother-in-law begged for a blowjob, sparking intense curiosity. "Using your mouth… sucking that thing… does it really feel good?! Sister looks like she's enjoying it… That's where he pees… isn't it gross? …But she looks like she loves it! …Is that thing… really that tasty…"
Watching Wen Wan stroke his cock with one hand, sucking and licking it from different angles like she was savoring her favorite childhood lollipop, Wen Ting felt a sudden urge to try it herself.
Back then, when her sister ate lollipops, Wen Ting wanted one too.
Now, seeing her sister eat her brother-in-law's cock, Wen Ting couldn't help wanting a taste…
This shameful thought didn't faze Wen Ting, who'd already given Li Bin a titjob. It even felt… fun.
Just then, Li Bin, lost in his wife's eager blowjob, noticed a figure at the door.
Focusing, he saw Wen Ting secretly watching his wife suck him off.
As Wen Wan deep-throated him, Li Bin shivered with excitement, nearly cumming from the thrill.
Wen Ting didn't seem to notice him, too focused on watching Wen Wan suck his cock, making Li Bin's eyes light up.
Her mother and sister were the best teachers for an innocent girl like Wen Ting.
Originally, Li Bin just wanted a quick blowjob from his wife to get in the mood before fucking his mother-in-law—a sneaky mother-daughter double play.
But Wen Ting's unexpected intrusion into this depraved feast made it even hotter.
"Perfect chance to let Wen Ting learn. Next time I get her to suck me off, she might not resist as much!" Li Bin smirked slyly, pretending not to see Wen Ting, stroking Wen Wan's silky hair and asking lewdly, "Baby, is your husband's cock tasty? Wanna suck this big cock every day? Hmm?"
"Mmm! Want it! Want it every day, can't get enough! Slurp slurp. Mmm!" Wen Wan sucked his cock, shooting him a playful glare, whimpering as she played along.
"Sss! Baby, want your husband to cum in your mouth? Hmm?" Li Bin panted, sneaking a glance at Wen Ting, continuing his filthy teasing.
"Want it! So bad! Mmm! Smack smack. Want you to cum for me! Fill my mouth! Slurp. I love swallowing your cum! Honey! Cum quick! Slurp slurp. Give it to me! Shoot it! Mmm!" To get Li Bin to cum faster and end this tense, thrilling romp, Wen Wan moaned, playing along with his dirty talk.
Wen Ting, watching wide-eyed from her hiding spot, gaped in disbelief, her curiosity and shock about sucking that monstrous cock growing stronger.
"Mmm! Mmm! Slurp slurp. Honey! Happy now? My mouth's so sore!"
After a frantic sucking session, sweat beaded on Wen Wan's forehead. The hot weather and squatting left her tired. Shooting her husband a playful glare, she turned to stretch her sore neck.
Just then, Wen Wan noticed a small head peeking from the doorway.
"Ah!!" Wen Wan screamed, blushing furiously as she stood, glaring at Wen Ting hiding behind the door, scolding, "Wen Ting!! What are you looking at?! You!!"
