Solved my Neighbor's problem

I live at home with my parents and attend the nearby university. I'm not the greatest student but am doing okay and rank in the middle every time. Our neighbors have their own business and were trying hard to have a child. He is 43 and she is 39 and I'm 24, I don't mix with them all that much. But my parents do and on New Year's Eve 2021 they were at the neighbor's party and at the party the alcohol was flowing, and everyone were overindulging. I hadn't attended the partying as I went out with friends and returned home around 1 in the morning. The lights were on next door and my parents weren't home, so I went to see what was happening. My parents were sitting and were really drunk, and the other guest were either passed out or starting to leave. My father got my mother up and they left, and I was asked to get my mother's favorite dish as she left. So, I went looking and found it in the kitchen covered food scraps. Giving a quick clean after binning the scraps, I returned to the living room, and nobody still there were awake. I heard someone asked for something and went to see what was required. I found our neighbor laying almost totally naked, and her husband passed out on the floor. She wanted him to fuck her, but he was out to it. She didn't recognize me as her neighbor but thought I was her husband. She asked me to fuck her, and I had already gotten a hard-on seeing her naked. I tried to tell her I wasn't her husband, and it didn't register with her. With her really wanting a fucking I decided to fuck her. It didn't take me very long to blow my load inside her and she wanted more, and I recovered my hard-on and fucked again. This time I lasted longer and after she fell asleep and so I went home. My parents were already in bed, and I put her dish on the kitchen table and went to my bed. I got up earlier than my parents and nobody was stirring at the neighbors. I went over to see if anybody was awake yet, no one was and going to the bedroom my neighbors were still where they were when I left earlier. I returned home and started making my breakfast and was eating when my parents came into the kitchen. They had coffee and nothing else. Anyway, several months later at dinner one evening my mother told us, her friend our neighbor was pregnant. She said they had sex on New Year's Eve and now were expecting a child. My mother added the husband had been so drunk he couldn't remember anything of that night. They now have a baby girl and luckily the baby takes after her mother.
