The passionate scene unfolds as the brother-in-law and sister-in-law lock lips, their hips grinding in sync. My wife sits on the brother-in-law's lap, her skirt hiked up, revealing her moist pussy. Her sister joins in, straddling the brother-in-law's chest as they continue their erotic dance. My heart races with jealousy and desire, feeling the tension build between the four of us. Our eyes meet, and I see the lust burning bright in theirs. This forbidden encounter fuels our ardor, making it more intense than ever before. As they take turns riding his hard cock, I can't help but imagine being in his place, feeling the warmth of their bodies wrapped around me.
