Hanasaki Koharu has been married to her husband for three years, but her husband often has to go on business trips for up to a week at a time. While bored, her friend was busy so she sent her son to take care of him for a few days. She met Shota once a few years ago. The boy is quite studious but seems a bit naughty and especially seems to like her breasts... Because Shota is still young, Mako often freely lets him do whatever he wants with her breasts. She also agreed to bathe with him, rubbing his penis when it was erect. And fire near straw also burns for a long time. A sex-starved woman and a breast-loving boy gradually overstepped their boundaries...
