STAR-673 Marina Shiraishi, a 29-year-old high school girl, is the only girl at her boys' school who is found to be an AV actress, and the sexually lustful adolescent boys start violating her to satisfy their sexual desires...

There's only one girl among the boys, and she's only 29 years old... Her lewd, mature body drives the sexually ravenous adolescent boys wild! The students peek at her changing clothes and get excited by her adult underwear, then get turned on by her tight bloomers during gym class, and when they find out she's an adult video star, they threaten her and force her into sex to satisfy their sexual urges. In the end, everyone finds out, but she brazenly goes after the young dicks herself, and has a bukkake orgy with the boys in the class!
