Well too bad. Because you will need to pay for that. Stop stroking and roll the dice. I will give you something easy to warm up with.
1-Slap your balls 20 times
2-Slap your dick`s head 20 times
3-Squeze your balls for 3 minutes. Make it hard
4-Stroke as fast as you can while rubbing your crotch for 2 minutes. No cumming!
5-Punch your balls 3 times.
6-Smash your balls 10 times
Are you done? Well roll again! We don`t want it to be too easy, do we? After you did the second task you may continue.
