Yui, my daughter-in-law, is always cheerful and energetic, diligently caring for me without ever showing any sign of displeasure. Just being around her has gradually lifted my spirits. During the day, we often spend time alone together, and her warmth brings comfort to my heart. One day, she came close to me in a vulnerable state, and I accidentally touched her soft, white breasts. Instead of pushing me away, she blushed shyly and smiled at me. Her response made my manhood stir with excitement for the first time in ages.
