I ended up staying at my brother's house to prepare for exams. However, I couldn't focus on studying because I was too distracted by my sexy sister-in-law. One day, I accidentally saw her underwear and got so excited that I jerked off. Worse yet, she caught me in the act. The next day, I honestly consulted with her. 'I can't forget your underwear and can't concentrate on my exam studies. Please help me,' I said. She was confused... but she put her hand on my hard, erect dick and said, 'Keep this a secret from my husband' as she jerked me off. Although I came, my erection didn't subside; instead, it became even harder, craving my sister-in-law. Before I knew it, I had lost my virginity to her... I felt guilty, the pressure to do well on my exams was immense, and my erect dick showed no signs of calming down. My sister-in-law gently comforted me in this state...
