I'm 14.5cm erect. That makes it 28 points for me.
I will spend:
5 points on mule kicks = 500 per leg
5 points on side leg raises = 500 per leg
15 points on hoola-hoop = 1500 cycles (excersise is important)
3 points on wearing panties = 3 hours (your reward)
Good luck in your punishment. You will come out a better man from this
