After a drinking party, the last train was gone, so I ended up letting my best friend's girlfriend stay at my place. We were both pretty drunk, and the mood turned kinda sexy. Even though I felt bad for my friend, I ended up sleeping with her... Turns out, she got along even better with me than with her boyfriend! The next morning, when my friend came to pick her up, she snuck off with me for another round of sex! At this point, I was seriously into her, and NTR wasn't enough anymore. I decided to break her up with her boyfriend and make her mine.
