Yes. It's happened to me. ? Not always but it depends on the person. Sad thing is one never knows when and if it'll happen. I remember the very first time and person it happened to me with. If I was really into the guy I used to love to swallow his cum. At first it happened with the same guy (a classmate in college) and it happened twice in a row so I stopped swallowing him. It's happened several times after that with random guys throughout the years but it's not a sure thing it will happen. I learned best swallow when at home or near a clean bathroom. ?
