Marc Dorcel's Russian Institute films can be counted on for solid jail-bait action, featuring great-looking Euro talent. With Frank Major/Franck Vicomte taking over for long-running house director Herve Bodilis, this 21st edition takes a fresh look at the format.Anna Polina and Tiffany Doll, surely two of the best Dorcel players over the years, take the central roles: Anna as the academy's headmistress and Tiff as our humble narrator and typically oversexed teen. Kudos to Doll from the git-go, as she remains convincing as a sweet young thing even though she was nearly 29 years old when shooting this one.As the BDSM title implies, Anna is given to inflicting corporal punishment on her femme charges, but director Vicomte is all about sex rather than pain. The mild spanking and habit of sticking panties in the girl's mouth is about as kinky as he gets, though one gal (Lola Taylor) does masturbate with a beer bottle in her pussy during a threesome with roommate Taylor Sands and visiting stud Max Fonda/Kristof Cale.Male cast is quite familiar from an uncountable number of Dorcel appearances, including art teacher Rico Simmons and inspector Renato. Old timer Bruno SX is even tapped for a group sex finale, and Polina provides enough mature sexuality to cover all the bases.
