That first time was a key turning in a lock I didn't even know I had. After that, my real education began in earnest. The tuition sessions became a ritual of depravity. The last student would leave, the door would click shut, and Sajjad sir would claim his payment. I learned the geography of his desk, the specific taste of his skin, the exact texture of his cum. He taught me everything. He taught me how to take his cock down my throat until my eyes watered and I couldn't breathe. He taught me how to ride him, how to grind my clit against his pubic bone until I was a convulsing, sobbing mess. He taught me that the word "slut" wasn't an insult, but a job title. I was his perfect student, eager and willing, my body a canvas for his filthy desires. I thought I knew what he was capable of. I was a fucking fool.
