You are a student "lưu ban" and a beautiful female teacher

When he first entered school, Mizukawa was Sakamoto's homeroom teacher. However, Sakamoto's academic performance was poor, causing him to be held back year after year. Mizukawa had to tutor him privately but still saw no improvement. And between them was a secret that couldn't be shared with anyone. Sakamoto had a big, strong, firm penis that Mizukawa couldn't stop thinking about. Her sexual desire was intense, and she made Sakamoto have sex with her repeatedly. Whether in the classroom, bathroom, or at his home, Mizukawa always wanted to drain Sakamoto's sperm, wanting him to fill her womb with it.

Even on the eve of the graduation exam, Mizukawa didn't let him off, still wanting him to ejaculate all his sperm inside her. And all of Sakamoto's knowledge, like a stream of sperm, flowed into Mizukawa's vagina, causing him to be held back for another year... The new school year has arrived, and Sakamoto meets his homeroom teacher Mizukawa again, signaling the start of another "tough" academic year for him...
