Kokoro is withdrawn and quiet, unable to assert herself, and unable to fit in with groups. Due to this personality, bullying and strained relationships, Kokoro has become a recluse and has stopped going to school. Persuaded by her teacher, Kokoro comes to school for the first time in a long time, but in the middle of a conversation with the teacher, a painful memory from the past flashes back and she panics and vomits. The teacher's lust rises up at the sight of Kokoro, which he never expected. He embraces Kokoro and gives her a deep vomit kiss in her vomit-covered mouth. He wants to see her vomit more! He starts with finger irama and then cock irama. Kokoro also receives an intense irama and vomits a lot! She responds with a runny nose, drool, and tears. "What you lack is confidence!" The teacher says in a passionate irama instruction, and Kokoro gradually awakens to irama and enjoys the pleasure of having her throat pounded. In addition, the physical education teacher and the class representative join in and give Kokoro throat instruction. The highlight is the self-vomit ejaculation while watching herself in the mirror with a dildo attached! The nasty irama instruction continues with continuous irama, irama 4P, and more.
