START-212 — My Serious Busty Teacher Took Pity On Me For Being Alone On The School Trip And Secretly Gave Me A Handjob. A Record Of The 10 Ejaculations I Had During The Stay. Momona Koibuchi

Koibuchi Momona's first completely subjective work. I was alone on a certain school trip. Momona, my homeroom teacher, was concerned about me, so I decided to go with her. I didn't notice her huge breasts during class, but I couldn't stop staring at them. Our three-day, two-night trip together became a wonderful memory, and we kept it a secret from the other students.
