After the drinking party, I missed the last train, so I let my best friend's girlfriend stay at my house. We were both drunk, so we got into a naughty mood. I felt bad for my best friend, but I ended up cuckolding her... Then, my best friend's girlfriend and I had better physical compatibility than I did, and the next morning, she hid from my best friend who came to pick me up and had sex with me again! When this happened, I got serious about it, and I wasn't satisfied with just NTR, so I shifted gears to make her break up with her boyfriend and make her my woman!
