i returned to my parents' house, where my older brother and his wife live, for the first time in several years. my niece momoka, who was still a child when i last saw her, had grown up to be cute and a little more mature. i was asked by my brother and his wife, who were going out, to stay home with momoka. she innocently invited me to play hide-and-seek. i still accompany the childish momoka. momoka hides in various places in the house. i chase after her. when i find momoka hiding in the closet, i see her panties. my heart skipped a beat. momoka is disappointed that she was found, but it's fun in the closet. big brother, come over here too. i entered the secret room closet that she beckoned me into. looking at my growing niece's body at close range, i became horny and couldn't hold it back anymore.
