One night, while visiting a friend's house, I encountered my friend's older sister, who was drunk and staggering. She seemed barely conscious, and when I secretly touched her, her body felt soft, warm, and dreamlike. Without her noticing, I boldly thrust into her from behind. As my desires escalated, I kept thrusting harder and faster, and gradually, she began to respond. The evolving intimacy between us as she remains in this hazy state is the highlight of this encounter.
