A married woman who has been married for 15 years. She lives a happy life, but her nightlife is almost non-existent, and even the occasional one is never satisfying. When such a married woman goes on a trip with her friend, she lies to her husband and gets on the sleeper train. She entrusts her sensitive body to a man she meets for the first time. Her fingers, tongue, and toys are not enough, so she is violently disturbed by inserting things other than her husband. GG-156 GG156 GG
