Because they wanted to improve their knowledge to prepare for the upcoming university entrance exam, the young couple invited each other to study together at home. After sitting at the table for a while, it seemed that both of them had forgotten their original purpose. Instead of studying the knowledge in class, they were curious and wanted to explore each other. They learned about sex from each other. Soon after, they had sex. Perhaps this was the most memorable group study session because it opened the door to maturity and understanding of sex that they had never experienced before.
