In "Buttman's Stretch Class: Detention," ass-obsessed director John Stagliano assigns three of his most alluring, sexually delinquent students to further flex their bodies, orifices and dirty minds. Voluptuous Kelly Divine, perky Jynx Maze and impossibly ass-blessed Alexis Texas return to Mr. Stagliano's classroom - his California beach home - to preen, pose and explore their incredible bodies using big anal toys, vibrators, speculums, clamps, clothespins and lots of imagination.
