If that happens to you with some escorts, I wonder why you chose a title for the thread that generalizes the issue to all of them. Sorry, but the unfair treatment of so many decent and hardworking professionals always annoys me.
Yes, some escorts want to cum in 15' and run away. Some others are clock watchers and will give you exactly what you paid for. Some others will stay with you beyond the agreed time. The last ones become my regular guys.
