Alluring XXX provocateur Sheena Shaw, an athletic graduate of director John Stagliano’s “Stretch Class,” takes over as instructor, and the filmmaker’s mind- and orifice-expanding series evolves into the rough, girl-girl education of “Sheena School.” Irrepressible Sheena trains four flexible sexual adventurers in the marathon (6 hours 35 minutes) movie, implementing her own gape and gag program for advanced pupils. Sheena’s class is packed with comely, pliable ass; the scenes are long, free form sessions. Limber brunette beauty Mischa Brooks pries the new professor’s elastic anus wide open with both hands and gets her pussy pounded by Sheena’s pink strap-on; Sheena blasts Brooks with a sensational outdoor enema. Tasty Brooklyn Lee studies foot sucking, rim jobs, big anal toys and gaping; she and her teacher deep-throat opposite ends of a double-dildo. Bubbly brat Jada Stevens enjoys tutelage in butt plugs, foot fetish and hot, flowing spit. Voluptuous, blonde BBW Mazzaratie Monica smothers Sheena’s face in floppy tits and big, bodacious butt. The ladies get off on double-toy-penetration and a vibrator. Ms. Shaw subjects her pussy to a graphic, wicked suction device and, throughout, shows off her talented, trained butthole. John loves the exercise of learning and pushing sexual limits. He says, “Shot in Buttman-style, this movie allows me to get beautiful shots and intimate interaction from the girls, but without my chatter. What a relief!” Extreme toys, lesbian body worship/contortion and orgasmic exhibitionism make “Sheena School” a playground of kinky fun from a female perv’s perspective. The student has become the master.
