Pinkiniki's BDSM workshop intensifies as the teacher's own desires ignite. She orders her students to pair off, to explore each other's bodies with the implements she's provided - riding crops, floggers, and leather straps. The room resonates with the sounds of impact and pleasure, as the women submit to their newfound roles. The teacher watches, her own sex pulsing with need, as she imagines the marks she's left on their skin, marking them as her pupils, her spankees, forever.
