"Ok lets continue. Since I'm a bit tired of giving you commands right now, you are going to work for yourself on the next task.
"You will stroke your cock for 5 minutes. Choose your speed and how you want to stroke. But you have to do it continuously. You can also massage your balls or nipples. If your hand gets tired switch to the other one, just do not stop to stroke. You may also edge. But if you do you have to wait for the feeling to subside. I then want you to count the seconds you needed to let it go away. After the five minutes you have to stroke your penis one time for every second!"
"Do you understand? Ok, then start!"
"And do not try to trick me I'm watching you."
