Ryo is exercising to release the libido that is left over from her husband's long business trip. One day, when her son's friend Kousuke visits, he is captivated by a young and strong meat stick he sees by chance. She couldn't stand it and pushed him. At first, she was squid many times and was delighted, but Kousuke was the owner of an unmatched cock that could not be settled in one or two times. The intense piston that never ends continues without end, and the body begins to scream at the climax that is repeated every day.
