SW-389 - Playing King's Game with drunk female coworkers: I was the only guy and got ravished

The only male employee on a company trip to a hot spring finds himself at the mercy of his drunk female coworkers. They start a 'King's Game' that forces him into various sexual situations—stripping, kissing, and constant stimulation of his member. He's trapped, surrounded, and pushed to his limits until he eventually ejaculates multiple times.
