Being introverted and quiet, unable to assert herself and not fitting in with the group, due to her personality, she became a shut-in and stopped going to school. Although she came to school for the first time in a long time due to the teacher's persuasion, in the middle of her conversation with the teacher, her painful memories from the past flashed back and she had a panic attack and vomited. Seeing Koharu Shizuki's unexpected appearance, the teacher's desire rose. He embraced her and gave her a thick vomit kiss with her vomit-covered mouth. "I want to see you vomit more!" and he went from finger irrumatio to phallus irrumatio. Koharu also received intense irrumatio and had a massive vomit! She drooled snot, saliva, and tears while responding. "What you lack is confidence!" and she gradually awakened to irrumatio with the teacher's passionate irrumatio guidance, and she felt the pleasure of her throat being banged. Furthermore, the physical education teacher and class committee also joined in, and they taught Koharu's throat. She attached a mold dildo to the mirror and had a self-vomit explosion while watching her own irrumatio. The continuous irrumatio, irrumatio 4P, and the relentless irrumatio guidance continued.
