Suicide hotline jerk
When calling into a suicide hotline, you jerk off as you tell the operator your story. As you get more emotional, you increase the speed of you jerking off. For those who are participating in this act, it kills two birds with one stone by relieving stress and having some sexual action.
As I told the operator my sob story, I came closer and closer to cumming, all while telling her about how I wanted to kill myself. The suicide hotline jerk has saved me many many times.
