My tutor, Mina-sensei, is my dad's lover! My mom is attending a tea ceremony class every Saturday, and taking advantage of this opportunity, my dad suggested that Mina-sensei become my tutor so that they could easily have secret encounters! And since then, every time Mina-sensei came to teach me, she would make an excuse to go outside to have sex with my dad! Because it happened many times, I became suspicious and followed sensei to witness them having sex. Not only that, every time my dad ejaculated inside her. With so many incidents, sensei is definitely going to get pregnant! And one time when I spied on them, Mina-sensei also noticed me, but instead of stopping, she deliberately moaned louder. After that, Mina-sensei suggested giving me a handjob to keep this secret.HMN-150 The boy silently watched his father fuck his tutor I agreed, and the inappropriate relationship between the tutor and my dad continued. But in the end, I couldn't take it anymore! I also wanted to have sex with this beautiful and seductive tutor! Waiting for my dad to get tired after sex and go to sleep, I asked Mina-sensei for permission to have sex with her. Mina-sensei agreed but with one condition, I had to be the top student in the upcoming exam...
