Beneath the watchful eyes of their deity, the sisters embark on a sacred journey, their bodies trembling with anticipation. The younger sister, her eyes closed, takes her brother's length into her mouth, swirling her tongue around the head, tasting the salt of his pre-cum. The elder sister, her hands guiding her sibling, helps her find a rhythm, their breaths synchronizing. As the brother's moans grow louder, the elder sister urges her sister to take him deeper, to feel him pulse against her tongue. The room echoes with the sounds of their shared ecstasy, a symphony of devotion and desire.
