My aunt Chisato and my niece Hibiki have been on good terms for a long time. Chisato liked Hibiki even as a woman, so she had mixed feelings when she heard that Hibiki had a boyfriend recently. One day, Hibiki comes to Chisato's house to say that she had a fight with her boyfriend. Chisato kisses the sleeping Hibiki. Hibiki is surprised, but she feels Chisato's kindness. Chisato violently entangles her tongue in such a sound.
