[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 (Censored)

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.
