A large number of adult videos were stored on the smartphone confiscated from her masturbation-obsessed son. Just to be sure, she checked the contents, and found that the videos only featured mature women of her age. Momo felt a heat tingling deep inside her body when she found out that her son liked mature women. She likes young men. Her son likes mature women. Supply and demand are perfectly matched. The fact that they are mother and daughter is only a trivial issue for Momo, who has an excessive sexual desire.
