A sadistic teacher delivers harsh punishments to disobedient students. The first lesson begins with spankings and shaving, followed by tying both hands and attaching large clips to the nipples. Clothespins are clamped all over the body and knocked off with a whip. Forced onto all fours, multiple sausages are shoved into the anus, enduring relentless torment. At night, the student is fully bound naked outdoors, forced to give a blowjob to the master while being urinated on. Back indoors, a nose hook is attached, enduring electric bulb torture as tears stream down the face pleading "It's hot, stop!"—but no mercy is given. The next day, the student is tied to a tower upside down, flogged with a whip, and subjected to a full course of candle wax torture and enemas. For the second lesson, another student receives chest slaps and whipping, bound upside down to a chair, and has tampons pulled out. Fish sausages are shoved into the face, followed by forced urination and defecation. Large clips clamp the nipples, the body is bound in a crucifix position to bamboo, completely helpless. Clothespins cover the body while enduring repeated whip strikes, then tortured with an electric stick, screaming in agony from low-frequency massager electrocution. Finally, anal beads are inserted followed by relentless pounding from an extra-thick dildo, driving the student to climax.
