Among the boys, there is only one girl, and she's 29 years old... with a tantalizingly mature body that arouses the lustful teenage boys! The students get excited peeking at her adult underwear while changing, lust over her form-fitting bloomers during gym class, and when they find out she's an AV actress, they threaten her into forced sex to satisfy their desires. In the end, it all comes out, but she brushes it off and actively seeks out young penises, engaging in a wild orgy with the entire class of boys!
