Q-gasm - When you get off quick and you're like wow that was fast or

When you get off quick and you're like wow that was fast or you just had a quickie and you're still shaking.

I had a Q-gasm so quick I didn't even know what happened.

I had a quickie and my heart was beating like I had just run a marathon.

I got a Q-gasm so fast I thought I had been hit by a truck.
