A beautiful swimming instructor named "Mai", who is number one at the sports gym, finds herself unexpectedly assigned to teach a class full of middle-aged men. Frustrated by her lackluster teaching and sexual harassment, the students decide to take matters into their own hands. They gang up on Mai, performing a brutal group revenge fuck. Overwhelmed by the sheer number of cocks surrounding her, Mai cries out in desperation while being pounded relentlessly. Her tight little mouth stretches wide as she takes every inch without complaint. Her pride and dignity are shattered when they rip off her revealing swimsuit, exposing her voluptuous breasts and wet, eager pussy. One after another, the men take turns violating her, filling her up with their hot cum. In the end, exhausted but satisfied, Mai realizes that maybe treating people like this isn't such a good idea... even if you're as irresistible as she is.
