Sometimes you will need a firm punishment to motivate and push you, to reach new lows. Other times you need some mental reinforcement. Maybe some longterm rules, to spice up your daily routine?
You will take one step at a time on a adventure down the rabbithole of your deepest desires. With every step you sink in deeper and with every inch sinken, your needs become stronger. Until one day you are bent over. Your ass is dark red and you thank your Master for his firm hand.
