In a moment of daring, I invite my best friend to join me in the WC, the thrill of potential exposure heightening our senses. She's a vision, her pretty face flushed with excitement as she watches me, perched on the toilet, slowly spreading my legs. The cool tile against my skin contrasts with the warmth between my thighs, her eager eyes taking in every detail. The sound of the lock clicking into place echoes in the small room, sealing our secret.
