The person living in the room across from us was a lustful, promiscuous older sister… The room across from our new place with my wife always had its curtains closed, so I didn't know who lived there. But one day, I saw the resident through a gap in the curtains. The resident was a woman, and she was... masturbating. What luck. Then, the neighbor noticed she was being watched and said, 'I have too much sexual energy; could you help me with it?' I couldn't refuse. From that day on, I spent days having sex with the promiscuous older sister next door.
