I married a man with a baby boy for two months. Although she was full of her husband, Tomoya's son, Tomoya, was not able to establish a relationship yet. One day, it is requested to help masturbation from Tomoya with too much sexual desire... From the pleasure that she was said to be her mother for the first time, Yura helps her son as a mother. However, Tomoya who did not fit by the ejaculation once in a while was able to help her again and again. At first I was able to go without being able to refuse, but I asked for help from myself.
