She had an affair with her boss during a business trip

Mai Shiomi had a long business trip with her boss. This was a mandatory trip so she had to go even though her boyfriend stopped her. He kept video calling to check on her after learning that the boss and Mai had to share a hotel room due to lack of room. That night, Mai and her boss went to receive guests. She drank a lot of alcohol, so she got drunk and her boss took her back to the hotel room. And then what the boyfriend feared happened, the boss took advantage of the opportunity to fuck Mai all night in pleasure.
