That JAV

Sumire was invited on a hot spring trip by her son. She had never been to a hot spring since she married her husband, who hates hot springs, so she was very happy. They arrived at a ryokan that looked nice and headed straight for the hot spring. Sumire was enjoying the open-air bath in the refreshing sunlight. A shadow sneaks a peek at her. To her surprise, her son was peeping at her bathing. That night, the son massages his mother to heal her. Whenever he touches his mother's body, he feels as if he is about to burst with secret feelings. Late at night, the mother quietly sighs in her sleep. The son has reached the limit of his patience. He gently turns over his mother's futon and begins to play with her body peeking through her yukata. Mother opens her eyes when she feels something strange on her body. Sumire is startled and tells her son to stop, but he forcibly kisses her. When her son tells her that he likes her as a woman, Sumire wonders if she has to hold back all the time. Sumire can't help but love her son and offers her body to him, telling him he can do whatever he wants...
