Yuna-sensei is a stunningly beautiful teacher adored by many students. Every day, I indulge in masturbation fantasizing about her. One day during a listening exercise, I hear her voice through the headphones: "Is your cock getting hard imagining my pussy?" That single line makes my heart race and my senses blur. Despite being in class, a vibrator is attached to my cock in the corner of the classroom, initiating a humiliating session. It feels as though the teacher is treating me like her pet, sending overwhelming excitement through me. I truly believe in my heart that I am Yuna-sensei's pet.
