Narumi and her mother-in-law who are alone for the first time while her husband goes on a company trip. I work on housework to distract the awkward atmosphere ... Beautiful breasts that shake every time you wipe and clean. Ripe and glossy peach butt that goes up and down. The defenseless behavior unknowingly robbed the reason of the breath. Narumi refuses once even though she is pressed for an excited breath. However, I am afraid that a groove will be created between my parents and children.
