The senior sister, an expert in the art of pleasure, takes her junior's hand, guiding it to her own wet slit. "Feel how slippery you're making me," she purrs, "Now, touch yourself like this." The junior mimics her sister's actions, her fingers tentatively tracing her own folds. The senior watches, her own pleasure mounting as she witness her sibling's awakening. She leans in, her breath hot on her junior's ear, "Let go, let your body take over. Enjoy your first vaginal orgasm, my love."
