A school sex movie by Sumire Mizukawa When she first entered school, Mizukawa was Sakamoto’s homeroom teacher. But Sakamoto’s poor academic performance caused him to be “retained” year after year. Mizukawa had to tutor him privately but still had no results. And between the two of them there was a secret that could not be told to anyone. Sakamoto had a big, strong, solid cock that Mizukawa could not stop thinking about. Her sexual desire was so great that she forced Sakamoto to fuck her over and over again. Whether in the classroom, the bathroom or at his house,… Mizukawa always wanted to drain Sakamoto’s sperm, wanted him to fill her uterus with his sperm. Even right before the graduation exam, Mizukawa still did not forgive him, still wanted him to ejaculate all his sperm inside her. And all of Sakamoto’s knowledge followed the sperm into Mizukawa’s pussy, causing him to be “retained” for another year… The new school year has come, Sakamoto meets his homeroom teacher Mizukawa again, signaling the beginning of another “hard” school year for him…
