[MIDA-584] My Naughty Sister-in-Law’s Seductive Smile and Revealing Underwear Drove Me Wild, Her Curvy Body Made Her a Drenched and Desperate Pleasure Seeker!

I was just trying to mind my own business when I caught that devilish grin on Yua’s face, my so-called sister-in-law. She knew exactly what she was doing, leaning over in that schoolgirl uniform with a mischievous glint in her eyes, giving me a full view of her provocative panty shot. The fabric was sheer and teasing, barely covering anything, and I could see every curve of her plump ass through it. My mind went blank, all reason lost as she wiggled those hips, making it impossible to look away. She was playing me like a fool, and I was too turned on to care, my thoughts consumed by the sight of her wet and stained underwear, a clear sign she was just as excited as I was.

Her plump ass was the center of attention, jiggling with every move as she bent over further, shamelessly appealing to me. The embarrassment on her face was a lie—it only fueled the fire, making her grind against the edge of the table until she exploded with excitement. I could hear her soft moans, muffled but desperate, as she rubbed herself through that soaked fabric, turning into a wet and stained bitch right before my eyes. She didn’t need words; her body screamed slut, every inch of her begging for attention, and I was helpless to resist, drawn in by the raw, filthy display of her sisterly tease.

By the end, she was a mess, panting and dripping, her schoolgirl uniform disheveled and her underwear a ruined testament to her lust. She looked up at me with that same devilish grin, now mixed with a satisfied exhaustion, as if to say she’d won this twisted game. My heart raced, still reeling from the sight of her plump ass and the way she’d appealed to me, leaving me craving more of her wicked, sisterly antics. In that moment, nothing else mattered—just the memory of her wet and stained body, a perfect slut who knew how to push every button.
