Sarah and Emily are two very mischievous British schoolgirls with far too much free time on their hands. Left alone one afternoon, the two start talking and giggling about spankings they have known. Sarah makes the silly mistake of suggesting Emily would be a wimpy spanker, so Emily sets out to prove she is vastly mistaken! Forcing the girl over her knee, she applies a strict spanking with her hand to her friend's upraised bottom. Some tricky questioning by Emily reveals that Sarah has been stealing and should be punished for real. No longer joking, Emily has Sarah bend over so she can paddle her hard, making her count each stroke and reply with a clear, "Thank you Miss." Any miscounting of stokes by Sarah will start the paddling from the beginning, which soon makes the girl very good at math!! Sarah finds applying both a leather strap and a French Martinet to her naughty friend brings new squeals of pain. Sarah cries, "This is really hurting me!", to which Emily scolds, "hold still girl!". An English style dose of the cane brings Sarah to tears, but the crying doesn't inspire Emily to stop the punishment. Her new idea is to have Sarah lie on a couch, with her legs held high in the air, bringing her bottom into full, rude view. Sarah can only sob, "You are so cruel." Someone sure has a very hot bottom! Sarah finally gets her moment to turn the table on Emily. Demanding Emily take her knickers down, Sarah gleefully exclaims, "You are getting exactly what you've given me, so who's crying now?" Sarah gives Emily the precise discipline she just received, and Emily is soon crying real tears as well. A well punished red bottom is the result, and Sarah gives Emily a gentle hug after her punishment.

Soon hugging leads to petting, and the girls get heavily into some girl on girl kissing and pussy play. They rub cream all over each other's sore, swollen bottom cheeks and are heavily involved with each other when Grandpa walks in! Realizing what the two girls have been up to, Gramps decides to show them what Real corporal punishment was like in his schooldays. Taking each girl in turn over his lap he begins their lesson with a sound OTK spanking, exclaiming "I'll teach you!". School punishments were common in his day and they were not just hand spankings - oh no - the strap and cane were frequently used to raise stinging welts and stripes upon bare bottoms. Grandpa shows he can use them all to the same effect upon grown-up schoolgirl behinds, remarking to them, "Still think it's fun, do you?" The girls have an unusual implement that Grandpa has not seen before - a swishy martinet, which Grandpa brings down with full force across the girls already sore rears. They are both crying buckets, but grandpa doesn't care, he only comments that,"Your cries are music to my ears." Wow, Grandpa is one mean guy! This is a feature length tape of one hour and twenty minutes of fantastic spanking, paddling, strapping, caning and martinet whipping action with girl girl and male spanks female action!!
