I lost all my memory after suffering a head injury in a traffic accident. I had no idea who I was or what my past life and experiences had been like. My doctor told me, "With the right amount of shock, your memories might gradually return." One day, a girl came to visit me. She called me "sensei" and acted as if she knew me well. At that moment, the doctor's words flashed through my mind—about needing a shock—and instinctively, I pinned her down. I tore her clothes, sucked her nipples, and frantically groped her body. She resisted fiercely, which was only natural. Yet driven by a strong desire to help me regain my memories, she offered her cooperation. In an instant, she asked, "Can I do it my way then?" and grabbed my cock. As I sucked her nipples, she carefully massaged my penis, slowly building its hardness and stimulating my aroused body. Before long, I was completely erect. "Think I'm ready? I'm all set!" she said, then suddenly opened her mouth wide, engulfing my cock deep into her throat. As she bobbed up and down rapidly—quiquiquiqui—I couldn't withstand the pleasure and erupted inside her mouth. This sensation... I feel like I've experienced it somewhere before. How many more times will I have to join bodies with her before my memories return?
