I discovered my best friend ejaculated inside my lover, now I am ejaculating in his spouse's vagina

I had the most bizarre experience last night. I was hanging out with my best friend, and things took a wild turn when I discovered he had just finished inside my girlfriend. I couldn't believe it, but I was also strangely aroused by the thought of it. I knew I had to act on it. I asked him if I could watch him do it again, and he agreed. We switched things up a bit, and I found myself taking his place, ejaculating inside my girlfriend. The feeling was intense, and I knew I had to continue this taboo journey. I asked my girlfriend if she would mind if I took her to my friend's house and had sex with his wife. She agreed, and we drove over. I met his wife, and we had a steamy session. I couldn't believe I was living out this fantasy. The sight of my friend's sperm inside my girlfriend only made it hotter. I ended up ejaculating inside my friend's wife, completing the circle of lust and desire. It was a wild night, and I can't wait to see what happens next.
