Having a standard masturbation session with one big difference, either during, or as you ejaculate (depending on the preference of the individual) you are vomiting or wretching due to illness or forced regurgitation.
I had an amazing sick wank the other day, managed to chunder just as I came it was magic.

When you are sick and you think wanking it will make you feel better. Instead it just makes you feel infinitely worse.
I was sick the other day and I decided that a sick wank it would be a good decision. Man was I wrong. It just gave me a huge headache.
