A GF of mine happened to have a class reunion while I was visiting. Although I was a year ahead, I knew a great deal of them, including this former classmate she had already fucked quite a few times.
She had arranged for me, her, and this guy to have a 3-way experience at the hotel where we were staying at after the event.
We had been there for a good hour or more, and he decided he wanted her to suck him off in his truck.
She came back to our table and told me she was going outside, and would be back in a few minutes, and had the gleam and wink in her eye, and I knew exactly what she was going to do.
I gave her a kiss, told her to have fun, and kissed her again when she returned from pleasuring him.
I could smell his musk, and the unmistakable saltiness of cum. And LOVED it!
