Jerk or Bust Challenge

Description: I know you love a joi challenge, and today's is going to test your endurance. i want you to stroke, at whatever speed, tightness, intensity that you like...until you hit that point of no return. don't worry, i'll tell you when that it. once we hit that point there is no going back and if you have to stop to keep from cumming prematurely than the ballbbusting will begin...and continue. will this lead you to hold back? or will you throw caution to the wind and indulge in the hedonistic pleasure of pumping until you can't think straight?
