From personal experience, there are not to many ladies that can make me cum more than once in 30 min..
Second time is usually with a hand job..
You know who you are sexy...
Ive always had a wank a few hours before for fear of a very short appointment but can you really go again or be told to fuck off i would probally last a hell of alot longer on the second try
My response is, depend on the client and the time, I thing.
