I had a fine neighbor at an apartment building I lived at a few years ago. Her apartment was right next to mine. Her bedroom was right next to my bedroom. You can hear anything through the walls. She was single, I was single and she was about 22yr old, 5'5" 110lbs blonde hair, big boobs , nice ass...pretty face.... I would invite my "dates" back to my apartment after going out , we would have hot porn style sex. I knew my neighbor would hear us, so i would give it to the girls even harder! I did this for a few months and finally my neighbor started coming up with reasons to come over....borrow a cup of sugar, made a cake had some left, ask me to check her oil...whatever just reasons to start coming over ...I knew she wanted it because I was making the girls scream ....My neighbor KNEW I had to be just doing the girls for sex because she would see it was a different girl every few days , but she didnt care. She heard all the screaming and moaning these girls were doing when we had sex. Now she was practically begging me to do her like that......When you know a hot girl wants you but doesnt come out and tells you, and shes playing these little games trying to get some, its like a sexual dream come true.
By the way, I ended up doing her and she confessed that every time i was having sex with the girls she would listen to us and masturbate.
If you ever get this chance, take it no matter what.
