NKKD-153 Take a married woman into the park's restroom during a family drive!

The woman who appears to be virtuous actually has another 'master' behind her husband's back. She feels guilty towards her kind husband, but she is subjected to sexual training by this other master and cannot resist him. Today, while enjoying a family day trip, completely ignoring it all, or perhaps even enjoying it, she receives a call from her master, easily summoned with just one phone call, to the public restroom in the park.
