Only for extreme losers! In this series I'm going to destroy your already non-existent stamina by training you to cum quicker and quicker. This ensures that you will never be able to have sex with any woman, because when I'm done with you, you won't be able to hold your cum for longer then 10 seconds! I will train you through 4 stages to ensure a gradual but certain decline of your stamina. Each stage needs to be repeated five times in a row before being allowed to progress to the next stage. If you fail to cum in the given time you will have to go back to the previous stage. In this stage you have 60 seconds to cum.... but don't start stroking until I command you to....
