Looking for this doujin I read about a month ago. A guy is hired to be a driver for a group of youtubers or some kind of influencers (2 guys, 3 girls). They visit a beach and have a rental home. At night, the driver spies on one guy and girl having sex. The rest of the story is basically just the driver sleeping with the other girls and then eventually getting the girl from the first night to cheat on her boyfriend.
Any help is much appreciated. Hopefully someone can help me find this again.
