I (Kitayama) started dating Miwa, a student I was tutoring. However, her mother, Marina-san, always interrupts us at the most opportune moments... Then, I was called out by Marina-san, and she began to torture my cock, saying, "I will manage your ejaculation!" It seems she thinks I'm not a man worthy of Miwa. I tried my best to endure it, but I was forced to ejaculate against my will multiple times. After that, I continued to be toyed with by Marina-san repeatedly, until I couldn't take it anymore and pushed her down instead...
