The famous Russian Institute reopens its doors for a new year dedicated to pleasure and sex education. But who's going to be the wildest this year? A student? Tina the new director? Or Lana... her daughter?

Anya Krey knows that her students are willing to do ANY thing it takes to get extra credit in their classes. Anal penetration, DP threesomes, and even female students engaging in a ball sucking, face-sitting threesome with their professor! Any other headmistress would've slapped these deviant neophytes and their perverted teachers with a reprimand...instead she uses what she knows to get her own sexual gratification from her staff and student body.

With their prim uniforms and angelic faces, you'd think butter wouldn't melt in their mouths. But the students from the Russian Institute never miss an opportunity to let their hair down, and their headmistress has a hard time keeping order in her establishment. To all appearances very serious students, Lexi and Darcia make the most of their "private classes" with a good-looking professor to expand their knowledge of male anatomy. Lilu makes it her duty to catch every man who passes her door - or rather to let herself be caught by them: the little slut invites boys into her room without hesitation, to discover the pleasures of double penetration, even taking the virginity of her best friend Luna's little brother. But don't imagine for a minute that Luna is innocent: she's the filthiest of all! The headmistress was relying on the head monitor to keep Luna in line, but the young woman has other plans and throws herself on the poor man at the beginning of her hour of class detention... Then, when Luna goes too far and leads the best students into her debauchery, introducing naughty Amirah to lesbian sex, the headmistress takes maters into her own hands.... and teaches these spoiled brats what happens when you arouse her appetite all day long!

Excitement rises among the students of the Russian Institute. For the first time, these young women go on a college trip to the countryside and intend to make this trip more sexual than cultural. Head of the troop, Apolonia, will have to be cunning to find a way to satisfy her fantasies. It's out of the question for her to return to the institute without having at least tasted the enjoyable local flavor.
