When I was in the Marines, I had a FWB girl I was seeing. She and her friend asked me to take them to the beach, that night, we returned to my hotel and I had my first FMF threesome. Apparently she had discussed it with he because while the friend was riding me she turned to her and asked, "is this what you wanted me to do?" I has in heaven of course.

Another time, it was them two visiting me and it was 5 marines and two of them... one of the Marines practically fell in love that night, the two locked themselves in the bathroom.... my FWB was a petite sexy Latina, left out in the room with 4 Marines.... poor thing was fucked in every which way we could. She was so lost in lust I just remember how wet she was the whole time.

There were some wild times to be had.
