After losing my wife, I lived in solitude until my son and his wife kindly suggested we move into a shared household. Their kindness touched me, especially his wife, Rio, who always cared for me with a warm smile and attentive support. One day, I accidentally witnessed something intimate between Rio and my son. Despite realizing I had seen them, Rio continued caring for me without hesitation, treating me with the same gentle demeanor. She has a strong libido and took control of my body with passionate dominance, bringing me repeatedly to climax without letting me move my hips. Her bold yet tender approach awakened new sensations within me, fulfilling me both emotionally and physically.
