This time, it's a filial piety project for grandpa! Riko-chan with her G-cup breasts volunteered to help out the troubled old man who wants to make a woman cum using his cock... Despite her shyness, she uses her expert tongue skills that even men her age can't imitate, making her cum repeatedly! If you take advantage of her kind personality, she'll ride his old cock in a reverse cowgirl position and let him cum inside her!! *This work will be released around September 2024 as part of NHDTB-965 "Respectful Magic Mirror".
