My daughter and her husband returned to her parents' house to give birth. A son-in-law who helps his mother-in-law Maiko with housework on behalf of his wife. I injured my finger due to unfamiliar household chores. Maiko reflexively holds her son-in-law's finger to stop the bleeding. - Maiko looks at her son-in-law who is surprised by it and changes to herself. That night, my son-in-law, who couldn't sleep, was looking at his licked fingers in the kitchen. A lightly dressed maiko came there. - A son-in-law who unexpectedly got an erection when he saw Maiko. Maiko is happy that she was excited by herself and buries her face in her son-in-law's crotch.
